Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the modalities to a preferred embodiment. Rather, it is intended to cover alternatives, modifications and equivalents as may be included within the spirit and scope of the modalities described as defined by the appended claims.

The following description generally refers to a mechanism that can be used to join at least two properly configured objects. In one embodiment, this can be accomplished without the use of conventional fasteners. Each object may include a bonding feature arranged to provide a magnetic field having appropriate properties. When the bonding features are placed in close proximity to each other, the magnetic fields can interact cooperatively based on their respective properties, resulting in the objects magnetically coming together in a desired and repeatable manner. For example, due at least in part to the cooperative nature of magnetic field interaction, objects can come together in a predetermined position and relative orientation without outside intervention. For example, cooperative magnetic interaction can result in objects self-aligning and self-centering in a desired orientation.

Objects may remain in the magnetically bonded state if and until a release force of sufficient magnitude is applied that exceeds the overall net attractive magnetic force. In some cases, however, it may be desirable to separate objects serially (along the zipper lines) in which case the release force need only be of sufficient magnitude to overcome the net magnetic attractive force of a pair. of magnetic elements at once. Connectors, like mechanical fasteners, are not necessary to join objects together. Furthermore, to prevent undue interference in the magnetic interaction between the magnetic bonding features, at least a portion of the objects in the vicinity of the magnetic resources may be formed of magnetically inactive materials such as plastics or nonferrous metals such as aluminum or non magnetic stainless steel.

Objects can take many shapes and perform many functions. When magnetically bonded together, objects can communicate and interact to form a cooperative system. The cooperative system can perform operations and provide functions that cannot be provided by separate objects individually. In another embodiment, at least one device may be used as an accessory device. The accessory device may be magnetically bonded to at least one electronic device. The accessory device may provide services and functions that may be used to increase the operability of the electronic device (s). For example, the accessory device may take the form of a protective cover that can be magnetically bonded to the electronic device. The protective cover can provide protection for certain aspects (such as a dial) of the electronic device while enhancing the overall look and feel of the electronic device. The magnetic bonding mechanism used to magnetically bond the accessory and the electronic device can ensure that the cover can only bond to the electronic device in a specific orientation. In addition, the magnetic union mechanism can also ensure proper alignment and positioning of the protective cover and the electronic device.

The protective cover may include at least one hinge portion. The hinge portion can be magnetically bonded to the electronic device using a magnetic union feature. The hinge portion may be pivotally connected to a tab that may be placed over a portion of the electronic device to be protected. Protective cover may include electronic circuits or other elements (passive or active) that may cooperate with the electronic elements in the electronic device. As part of this cooperation, signals may be passed between the protective cover and the electronic device that may be used, for example, to modify electronic device operations, electronic circuit operations. ^ and ^ so on.

As an example, the electronic device may include a magnetically sensitive circuit such as a Hall Effect sensor and as such may detect the presence of a magnetic field. The Hall Effect sensor can respond to the presence (or absence) of the magnetic field by generating a signal. The signal can be used to change the operating state of the electronic device. Thus, the protective cover may include a magnetic element, such as a permanent magnet, having a magnetic field that can cause the Hall Effect sensor to generate the signal. The magnetic element can be positioned on the protective cover at a location that triggers the Hall Effect sensor to generate the signal when the cover is placed on or in proximity to a surface of the electronic device. The signal may indicate that the protective cover is in a predefined position relative to the electronic device which may result in a change in the operating state of the electronic device. For example, with the protective cover portion having the magnetic element in close proximity to the Hall Effect sensor, the magnetic field of the magnetic element may cause the Hall Effect sensor to generate a signal. The signal can be used, in turn, to change the operating state to one consistent with the display of the electronic device being fully covered. On the other hand, when the protective cover portion having the magnetic element is removed to the point where the Hall Effect sensor no longer responds to the magnetic field of the magnetic element, then the Hall Effect sensor may generate another signal. The other signal may result in the electronic device entering a different operating state consistent with at least a portion of the display being uncovered and visible.

These and other embodiments are discussed below with reference to Figures 1 - 40. However, those skilled in the art will readily find that the detailed description provided herein with respect to these figures is for explanatory purposes only and should not be interpreted. as limiting. For the remainder of this discussion, a first and second object, each suitably shaped to magnetically bond according to the described embodiments will be described. It should be noted, however, that any number and type of properly configured objects can be magnetically joined together in a precise and repeatable manner. In particular, for simplicity and clarity, for the remainder of this discussion it is assumed that the first object takes the form of an electronic device and in particular a handheld electronic device.

Figure 1 is a simplified block diagram of article 10 and electronic device 12 that may be releasably joined in a desired and repeatable manner. More specifically, article 10 and electronic device 12 may come together in a predetermined position and relative orientation without external intervention and without the use of mechanical fasteners. Article 10 and electronic device 12 may remain joined if and until a release force is applied that overcomes the engagement between them. In some cases, however, it may be desirable to separate article 10 and electronic device 12 serially (along the lines of a zipper) in which case a release force may be applied which may undo the engagement between article 10 and the electronic device 12 around one coupling component at a time. For example, a bonding component may include a suitably associated pair of magnetic elements, one in article 10 and a second in electronic device 12.

The electronic device 12 can take many forms. For example, electronic device 12 may take the form of a portable electronic device. In some examples, the portable electronic device may include housing 15. Housing 15 may surround and provide support for the components of the portable electronic device. The housing 15 may also provide support for at least one large prominent display occupying a substantial portion of a front face of the portable electronic device. The dial can be used to display visual content. Visual content may include still images, visuals, text data as well as graphical data that may include icons used as part of a graphical user interface, or GUI. "In some cases, at least ~ a display portion may be touch sensitive. By touch sensitivity it is intended that during a touch event, an object (such as a finger, pen, and so on) may be placed in contact. with or in proximity to an upper surface of the dial. The specifics of the touch event (location, pressure, duration and so on) can be used to provide information for the portable electronic device for processing. In addition to or in lieu of the information being provided to the portable electronic device, the information may be provided by the portable electronic device in a tactile manner using, for example, haptic triggers. and not by limitation since the electronic device can be widely varied. In one example, the portable electronic device is a computer desktop device such as, for example, the iPad ™ manufactured by Apple Inc. of Cupertino, CA.

Article 10 may be widely varied and may take many forms such as, for example, an electronic device accessory or equipment 12. As an accessory, article 10 may be configured as a cover, a platform, a dock, a hanger, an input / output device and so on. In a particularly useful form, article 10 may take the form of a protective cover which may include an element, such as a flap, which may be positioned over the dial of the portable electronic device. Like electronic device 12, article 10 may also include housing 17 which may surround and provide support for the components of article 10.

Either or both, article 10 and electronic device 12 may include bonding features. For example, article 10 may include coupling system 13 and electronic device 12 may include corresponding coupling system 14. Coupling system 13 may cooperate with corresponding coupling system 14 to join article 10 and the electronic device 12 in a removable manner. When joined together, article 10 and electronic device 12 can operate as a single operating unit. On the other hand, in a separate mode, article 10 and electrode 12 may act separately, and if desired, as two individual parts. Joining systems 13 and 14 may be configured in such a manner that article 10 and electronic device 12 may be joined in a desired and repeatable manner.In other words, joining systems 13 and 14 may repeatedly align article 10 and electronic device 12 together so that they are consistently in a predetermined position at each other. relationship to each other.

Joining capabilities can be widely varied. Joining may be provided by various types of couplings including mechanical, electrical, static, magnetic, frictional and / or the like. In one instance, the union cannot be observed from outside the article and / or the electronic device. For example, the article and device may not include visible external joining features that adversely affect the appearance and impression or ornamental appearance (eg spring closures, latches, etc.), but preferably joining features that they cannot be viewed from outside the article or device and thus do not affect the appearance and impression or ornamental appearance of the article or device. By way of example, the bonding features may be provided by attracting surfaces that do not disturb the external surfaces of the article or device. In one embodiment, at least a portion of the bonding features utilize magnetic attraction to provide some or all of the bonding force.

Joining systems may include one or more joining features. If multiple resources are used, the way they stand can be the same or different. For example, in one implementation, a first joining feature uses a first joining means while a second joining feature uses a second joining means that is different from the first joining means. For example, the first coupling means may use a friction coupling while the second coupling means may use magnetism. In another implementation, a first joining feature uses a first joining means while a second joining feature uses the same or similar joining means. For example, the first and second means of union may be provided by magnets. Although half-union may be similar, it should be noted that the configuration of resources may differ depending on the needs of the system. In addition, any number and configuration of joining means may be used.

In the illustrated embodiment, the joining systems 13 and 14 include,

each of at least one first set of corresponding joint features 13a / 14a and a second set of corresponding joint features 13b / 14b. The coupling facility 13a may cooperate with the corresponding coupling facility 14a to join the article 10 and the electronic device in a removable manner. In a particular implementation, this is accomplished with magnetic attraction. In addition, the bonding feature 13b may cooperate with the corresponding bonding feature 14b to further join article 10 and the electronic device in a removable manner. In a particular implementation, this is accomplished with magnetic attraction. By way of example, bonding features 13a / 14a may be provided in a first location while bonding features 13b / 14b may be provided in a second location.

In a specific example, coupling facility 14a may, in cooperation with coupling facility 13a, secure electronic device 12 in article 10. In another example, coupling facility 13b may secure article 10 of electronic device 12 using joining feature 14b. It should be noted that the joining systems 13 and 14 of this example may be separated or they may cooperate to produce the joining. If they cooperate, the joining features 14a and 14b correspond with or fit with one or more joining features 13a and 13b. In either case, the bonding features in any of these examples may be realized through mechanical, static, suction, magnetic bonding and / or the like.

The placement of joining systems and joining features within joining systems can be widely varied. With respect to the electronic device 12, the joining system 14 may be placed at the front, back, top, bottom and / or sides. The coupling features 14a and 14b may be placed at any location within the coupling system 14. Thus, the coupling features 14a and 14b may be placed anywhere with respect to the housing and / or the dial. In one example, the joining features 14a and 14b may provide engagement along one or more sides of the housing (e.g., top, bottom, left, right). In another example, the coupling features 14a and 14b may provide engagement at the rear of the electronic device 12. In yet another example, the coupling features 14a and 14b may provide engagement at the front (e.g., where, if a dial is located) of the electronic device 12. In some cases, a combination of bonding features may be located in different regions of the electronic device 12, such as on the sides and front. In one embodiment, the bonding system 14 including the bonding features 14a and 14b does not disturb the surfaces of the electronic device 12. Similarly, the bonding system 13 and in particular the bonding features 13a and 13b do not disturb the surfaces of the electronic device. Article 10. According to one embodiment, the union resources may

include magnetic elements. The magnetic elements may be configured to assist in positioning article 10 relative to electronic device 12 in a corresponding arrangement. The magnetic elements may further assist in securing article 10 and electronic device 12 in a corresponding engagement. It should be noted that the engagement of article 10 and electronic device 12 may be reversed by applying an appropriate release force that allows article 10 and electronic device 12 to separate back to individual objects. However, the magnetic elements may allow the article 10 and the electronic device 12 to subsequently return the corresponding coupling without requiring any type of mechanical or other fasteners. In this way, the magnetic elements provide a repeatable and consistent engagement between article 10 and the electronic device 12.

Article 10 and electronic device 12 may further include components 16 and 18 respectively. Components 16 and 18 typically depend on the configuration of article 10 and electronic device 12 and may be, for example, mechanical or structural components used to provide support, or they may be operational / furtonal components that may provide a specific set of components. operations / functions. The components may be dedicated to their respective devices or they may be configured for coupling with aspects of the corresponding article or device (eg wired or wireless). Examples of structural components may include moldings, walls, fasteners, stiffeners, movement mechanisms (hinge), etc. Examples of operating components may include processors, memory, batteries, antennas, circuitry, sensors, displays, inputs, and so on. Depending on their desired configuration, the components may be external (i.e. exposed on the surface) and / or internal (e.g. embedded in the housing).

Figures 2A and 2B are simplified perspective views of article 20 which can be releasably coupled to the electronic device 22 via a magnetic coupling system according to a described embodiment. Article 20 and electronic device 22 may generally correspond to those discussed with respect to Figure 1. In one embodiment, the magnetic union system may be personified as a magnetic surface 24 (shown by dashed or shaded lines) and more. particularly as a magnetic surface 24 on the sides of the electronic device 22. The magnetic surface 24 may provide a magnetic field which may cooperate with a corresponding bonding feature in article 20 when placed in close proximity to each other. The magnetic field can establish a net magnetic attractive force that can pull the article 20 and the electronic device 22 together to the corresponding coupling along the coupling surface 26, as shown in figure 2B.

In other words, the magnetic field provided by the magnetic surface 24 may have properties such that the net magnetic attractive force between the article 20 and the electronic device 22 is substantially perpendicular to the engaging surface 26. Moreover, the field Magnetic force may result in the net magnetic attractive force between article 20 and electronic device 22 being applied uniformly along the coupling surface 2677.No loosening ~ article 20 and electronic device 22, no force-release can be applied in the two objects united in order to overcome the net magnetic attractive force provided by the magnetic union system.

It should also be noted that although only one sidewall is shown, in some cases different sidewalls and possibly a combination of sidewalls may be used depending on the needs of the bonding interface. It should be noted that the use of magnetic union excludes the need for mechanical joints such as fasteners. Moreover, the lack of mechanical joints and the uniformity of the general magnetic attractive force can leave the surfaces of article 20 and electronic device 22 unchanged helping to create a unitary appearance through which article 20 and electronic device 22 can appear as a single, unified entity. Uniformity in appearance can improve the overall aesthetic appeal of both article 20 and electronic device 22. In one embodiment, a magnetic surface can be created.

embedding magnetically attractive elements in the form of the magnetic bonding feature within the sidewalls of the electronic device 22 and / or article 20. That is, the magnetically attractive elements may be arranged within the article 20 and electronic device 22 such as For example, within the housing of the electronic device 22. In this configuration, the housing may be formed of non-magnetic material such as plastic or non-ferrous metal such as aluminum. In this way, the magnetic force lines can be configured to work through the housing walls. The magnetic bonding features do not disturb the physical appearance of the outer surfaces of article 20 and electronic device 22. The magnetically attractive elements in article 20 and electronic device 22 may be arranged to produce magnetic fields that can cooperate with each other to generate a force. magnetic attractor joining article 20 and electronic device 22 together in the corresponding coupling. The magnetic attractive force being configured to generate a magnetic attraction force normal to the coupling surface 26 between the electronic device 22 and article 20.

The magnetic attractive force between magnetic elements corresponding to article 20 and the electronic device 22 may also be applied uniformly along the coupling surface 26. The uniformity of the general magnetic attractive force along the coupling surface 26 may be a result of the uniformity of the separation distance between corresponding magnetic elements in article 20 and electronic device 22. The uniformity may also be a result of the consistency of the magnetic flux density between corresponding magnetic elements in article 20 and electronic device 22. A The uniformity of the liquid magnetic union can be facilitated by the surfaces of article 20 and electronic device 22, each forming a well-matched fit with each other. For example, one surface may be flat or have a concave geometry while the other surface may have a convex geometry as associated. In this way, by firmly adjusting, the separation distance between each of the corresponding magnetic elements in article 20 and electronic device 22 can be reduced to a minimum. Conforming the surface shapes can also improve the overall look and feel of the article 20 and the electronic device 22 by reducing or eliminating the appearance of a joint on the coupling surface 26. This inconsistent quality can provide the illusion of an en- - only when Article 20 and electronic device 22 are joined. In addition to improving overall look and feel, consistency

The separation distance between the magnetic elements can make the bonding force between the article 20 and the electronic device 22 uniform across the coupling surface 26. In this way, the coupling force can be uniformly distributed across the surface. 26, preventing weaknesses, and so on that could otherwise affect the overall integrity of the coupling between article 20 and the electronic device 22.

Figures 3A and 3B are simplified perspective views of article 30 which can be releasably joined to an electronic device 32 via magnetic coupling system 34 and corresponding coupling system 36. It should be noted that this particular embodiment is similar. 2A, 2B, except that the magnetic surfaces previously placed on the sidewalls are now located on one face of the electronic device 32 and, optionally, an opposite face on Article 30. For example, on the In the case of an electronic device including a dial, the magnetic elements of the magnetic union system 34 may be embedded behind the surface of the dial.

Figure 3B shows article 30 and electronic device 32 magically joined together to form cooperating system 38. As part of system 38, electronic device 32 and article 30 can cooperate to provide unavailable resources. by Article 30 or electronic device 32 separately. For example, Article 30 may take the form of a cover that may provide protective features. In one embodiment, the protective cover may be used to support and protect the electronic device 32 while being transported or stored (for example, covering the surface of the dial). Due to the removable nature of the magnetic union between the magnetic union systems 34 and 36, article 30 can be easily separated when the electronic device 32 is to be used and subsequently rejoined when desired.

The placement of the magnetic elements may be such that only certain magnetically sensitive elements within the electronic device 32 are affected by the magnetic field generated by the embedded magnetic elements. For example, a Hall Effect sensor may be used to detect whether or not article 30 is magnetically attached to and covering all or a portion of the display of electronic device 32 using the magnetic field generated by a magnetic element located in article 30. On the other hand On the other hand, a magnetically sensitive element in the electronic device 32 such as a compass having an external magnetic field (ie, such as that provided by the earth) need not be unduly affected by the magnetic field lines generated by the embedded magnetic elements. . Therefore, the magnetic elements may be limited to these locations in the electronic device 32 positioned far from the magnetically sensitive elements such as the compass.

Figures 4A and 4C are simplified perspective views of "Article 40 which can be remotely mocked on the electronic device42 via a magnetic system 44. This embodiment is similar to that shown in Figures 2A, 2B and 3A, 3B in which the magnetic system 44 may include multiple magnetically attractive elements and that article 40 and electronic device 42 generally correspond with those mentioned in the previous figures.For example, a set of magnetically attractive magnetic elements 44a may be placed relative to one side of the article 40 and electronic device 42 while a second set of magnetically attractive elements 44b may be placed relative to a face of article 40 and electronic device 42. As shown in figure 4B, cooperating system 46 may be formed by placing article 40 and electronic device 42 in close proximity to each other such that the magnetic elements 44a on the sides of the article 40 and 42 are attracted magically beyond the magnetic elements 44b located on the face of the electronic device 42 and article 40. The general magnetic attraction generated on the side and face may be sufficient to hold article 40 and the electronic device 42 in one corresponding coupling to form the cooperating system 46.

In one embodiment, as shown in Fig. 4C, the cooperating system 46 is presented in an open configuration in which article 40 is used as a cover for the open and close electronic device 42. That is, article 40 may act as a protective cover of electronic device 42. In this embodiment, article 40 may include gasket 48 that joins along the side of electronic device 42 and tab 50 that joins on the front face. of the electronic device 42 and more particularly on the upper face 52. The upper face 52 may correspond with a display. In one implementation, tab 50 may move relative to joint 48. Movement may be widely varied. In one example, the tab 50 may pivot relative to the joint 48. The pivot may be widely varied. In one example, the pivot may be enabled by a hinge mechanism. In another example, the pivot may be enabled by a fold. In addition, the flap may be rigid, semi-rigid or flexible. Thus, article 40 may form an open configuration where the tab 50 is positioned away from the electronic device 42 (shown 52), and a closed configuration where the tab 50 is positioned adjacent the electronic device 42. (Dial 52 is covered as shown by the closed pattern of FIG. 4B).

In one embodiment, gasket 48 is located only on a

while flap 50 is only located on top face 52. In doing so, the other surfaces of electronic device 42 are left exposed. As a result, the beauty of the electronic device can stand out as the article is merged into the electronic device. In addition, this may leave better access to I / O and connectivity-related functionality (eg, buttons, connectors, etc.).

Although the purpose of the magnetic elements is similar, that is, to attach the article to the electronic device, it should be noted that these mechanisms can vary widely. In some cases, magnetic fields may be configured differently. By way of example, the side-mounted magnetic surface may provide a first magnetic force and the forward facing magnetic surface may provide a second magnetic force that is different from the first magnetic force. This may be due in part to different holding requirements as well as different surface areas, ie available space, and their effect on the internal components of the electronic device. In one example, the side-mounted magnetic surface provides a greater clamping force to secure the article to the electronic device, that is, it is the primary clamping force while the forward-facing magnetic surface is the secondary clamping force. In one example, tab 50 includes multiple sections that are semi-

rigid and bend to each other to make the flap movable and flexible. In one embodiment, the tab 50 may be folded into one or more different configurations and in some cases may be retained at these settings using a magnetic system similar to that described above. These and other embodiments will be described in more detail below. Furthermore, it should be noted that the embodiments described are not limited to coverages and that other configurations may be used including, for example, as an accessory device with a suspending apparatus, as a support mechanism for the electronic device for measuring. improve display display and as a support mechanism for inserting touch events into a touch portion of the display and so on.

The electronic device and article can take many forms. For the remainder of this discussion, the electronic device is described in terms of a portable handheld computing device. Thus, the figure shows a top perspective view of the electronic device 100 according to the described embodiments. The electronic device 100 can process data and more particularly media data such as audio, visuals, images, etc. For example, the electronic device 100 may generally correspond to a device that may function as a smart phone, a music player, a game player, a visual player, a personal digital assistant (PDA), a computer tablet and the like. The electronic device 100 may also be handheld. With regard to being hand held, the electronic device 100 can be held in one hand while being operated by the other hand (ie no reference surface such as a precise desk). Therefore, the electronic device 100 may be held in one hand while operational input commands may be provided by the other hand. Operational input commands may include operating a volume key, a locking key, or entering a touch surface ta! as a touch display device or a touch pad.

Electronic device 100 may include housing 102. In some embodiments, housing 102 may take the form of a one-piece housing formed of any number of materials such as plastic or non-magnetic metal which may be forged, molded or otherwise formed. another shape transformed into a desired shape. In those cases where the electronic device 100 has a metal housing and incorporates radio frequency (RF) -based functionality, a portion of the housing 102 may include transparent materials to the ceramic-atrplastic-and-housing radio 102. be configured to include multiple internal components. For example, housing 102 may include and support various structural and electrical components (including integrated circuit chips) to provide computing operations for electronic device 100. Integrated circuits may take the form of chips, chip assemblies or grinding wheels. modules, any of which may be mounted on the surface of a printed circuit board, or PCB, or other support structure. For example, a main logic board (MLB) may have integrated circuits mounted thereon that may include at least one microprocessor, semiconductor memory (such as FLASH) and various support circuits, and so on. Housing 102 may include aperture 104 for housing internal components and where necessary may be sized to accommodate the display assembly for displaying visual content, the display assembly being covered and protected by the protective layer 106. In some cases, the The dial assembly can be touch sensitive allowing tactile inputs that can be used to provide control signals for the electronic device 100. In some cases, the dial assembly may be a large prominent display area that covers most of the Real estate in front of the electronic device.

The electronic device 100 may include a magnetic bonding system which may be used to magnetically connect the electronic device 100 to at least one other suitably configured object. The magnetic bonding system may include various magnetic bonding features distributed within and in some cases connected to the housing 102. For example, the magnetic bonding system may include first magnetic bonding feature 108 and second magnetic bonding feature 110 different sides of the electronic device 100. In particular, the first magnetic bonding feature 108 may be located in close proximity to the side wall 102a of the housing 102. The second magnetic bonding feature 110 may be located within the opening 104 near of the sidewall 102b of housing 102. In such embodiments where the electronic device Ί00 includes a cover glass dial substantially opening the opening 104, the second bonding feature 110 may be placed below the cover glass.

Placing the first magnetic bonding feature 108 on the sidewall 102a may facilitate the use of the magnetic bonding feature 108 for magnetically joining the electronic device 100 to another suitably configured object such as another electronic device or an accessory device. . Thus, without loss of generality, the first magnetic bonding feature 108 will hereinafter be referred to as the bonding feature of the device 108.

The placement of the second magnetic coupling feature 110, on the other hand, may facilitate the use of the second magnetic coupling feature 110 to secure aspects of another joined device in the electronic device 100 by means of the device coupling feature 108. Thus, the The general bonding between the other device and the electronic device 100 may be firmer than the bonding through the first bonding feature 108 only. Thus, and again without loss of generality, the second joining feature 110 will hereinafter be referred to as a firm joining feature.

Although not expressly shown, it is understood that the various magnetic bonding features of the magnetic bonding system may be located at any appropriate location in the housing 102. For example, magnetic bonding features may be located on a lower surface. housing 102 or along sides 102c and 102d of housing 102. As shown in Figure 6, the joining feature of the device

108 and tight coupling feature 110 may each include one or more magnetic elements. In one example, the bonding feature of device 108 may multiply the magnetically interacting magnetic elements to provide the magnetic field 112 (only a portion of which is shown). In other words, the properties (shape, field strength, and so on) of the magnetic field 112 may be based on the interaction of the magnetic fields generated by each of the magnetic merits, in this manner. The magnitude of the magnetic element can be altered simply by arranging the properties (ie, physical shape, relative size and constituent magnetic polarities) of each of the magnetic elements. For example, each of the magnetic elements may be of varying sizes and may be arranged along a geometric axis. In this way, the magnetic properties of each of the plurality of magnetic elements can act together to establish the general properties of the magnetic field 112.

In some cases, the portion of the magnetic field 112 that is used in the magnetic bond between the bonding feature of device 108 and another device may be enlarged using a magnetic shunt (not shown). The magnetic shunt may be formed from magically active material, such as steel or iron, and be placed in a position that causes magnetic field lines that would otherwise be directed away from the bonding region to be at least partially redirected to the join region. The redirection of magnetic field lines can have the effect of increasing the average magnetic flux density in the joining region.

The bonding feature of device 108 can operate in an active state as well as in the idle state. The magnetic flux density B112 may equal or exceed the magnetic flux density threshold Bjimiar within the outer surface of the housing 102, but not in the idle state. In other words, the magnetic flux density B112 of the magnetic field 112 on an outer surface of the housing 102 is less than the magnetic flux density threshold Bnmiar- The Biimiar magnetic flux density threshold representing a magnetic flux value below which magnetically sensitive devices (such as a magnetic stripe on a credit card) may remain substantially unchanged. Furthermore, the presence of a magnetically active material (such as steel) in the region outside the electronic device 100 will not in itself trigger the bonding feature of the device 108 to transition from the idle state to the active state. "As mentioned above, when the device connector feature 108 is inactive, the magnetic flux density B112 of the magnetic field 112 on the outer surface of the side 102a of the housing 102 is less than the Biimiar magnetic flux density threshold. More particularly with respect to the bonding feature of device 108, the magnetic flux density Bn2 may vary as a function of the distance χ (ie B = Bn2 (X)) of the magnetic elements, so when the bonding feature of the device 112 is inactive, the magnetic flux density B112 (X) can satisfy equation (1) B112 (x = Xo +1) <Biimiar, Equation (1)

where t is the thickness of housing 102 on side 102a and

Xo is the distance from the inside of side 102a to the magnetic elements.

When the bonding feature of device 108 is inactive, any leakage of magnetic flux in the near region outside of electronic device 100 (ie B112 (x> X0 + t)) is low enough that there is little likelihood that magnetically sensitive devices in the near region are adversely affected. However, it should be noted that even in the inactive state, magnetic field 112 can have a flux value of magnet Bi12 (x = X0 + t) that satisfies equation (1) and is still high enough to interact with the field. from another device placed relatively close to it. In this way, the other magnetic union feature appropriately configured on the other device can be used to activate the magnetic union feature of device 108 even though equation (1) is satisfied.

Properties of the magnetic field 112 may include at least field strength, magnetic polarity, and so on. The properties of the magnetic field 112 may be based on the combination of the magnetic fields of each of the magnetic elements included in the magnetic bonding feature 108. The combined magnetic fields may form in the aggregate magnetic field 112. For example, the elements The magnetic fields can be arranged in such a way that the combination of the respective magnetic fields results in the desired magnetic field properties (such as field strength). For example, the combination of an arrangement of the magnetic elements may result in the magnetic field 112 having characteristics (such as polarity and intensity) that are, in most cases, symmetrical about a particular geometric axis (such as a centerline). geometric).

On the other hand, the magnetic elements may be arranged in such a way that the combination of the magnetic fields of the magnetic elements may result in the magnetic field 112 having at least one property that is antisymmetric around the centerline. For example, a magnetic element on one side of the centerline may be positioned with an upwardly pointing north magnetic pole while a corresponding magnetic element on the other side of the centerline may be arranged with the upwardly pointing south magnetic pole. Therefore, the magnetic properties of the magnetic field 112 may be adjusted in any way deemed appropriate to provide a desired corresponding engagement. For example, the magnetic properties of the magnetic field 112 may be modified by arranging the magnetic elements in such a way that the magnetic field 112 can interact cooperatively with another magnetic field (from another magnetic union system, for example). The cooperative interaction between the two magnetic fields can result in the two objects being magnetically joined together in a well-defined, precise and repeatable manner.

The properties of the magnetic field 112 may be stable. By stable it is intended that the properties of the magnetic field may remain essentially unchanged for a prolonged period of time. Therefore, a stable version of magnetic field 112 can be created using magnetic elements having properties that are essentially constant (or nearly constant) over an extended period of time or at least any changes in one component are offset by a corresponding change in another component. . The magnetic elements may be physically arranged in a fixed or at least substantially fixed configuration with respect to the other magnetic elements: For example, each of the magnetic elements may have fixed sizes and polarities arranged in a specific order relative to each other providing the properties. desired (shape, intensity, polarity, etc.)

Therefore, depending on the properties and nature of the magnetic elements, the shape of the magnetic field 112 may remain substantially unchanged over the extended time period (such as the expected operating time of the electronic device 100). ).

In some modalities, however, the properties of the

Magnetic power 112 may be varied by modifying a magnetic or other physical property of at least one of the magnetic elements. When at least one magnetic element has magnetic properties (for example, a polarity or field strength) that can be modified, the resulting magnetic field can also be modified. Thus, in some embodiments, at least one of the magnetic elements may be characterized as having dynamic magnetic properties. By dynamics it is planned that at least one magnetic property, such as polarity, can be modified. Thus, the properties of the magnetic field of the resulting magnetic field may also vary. The resulting magnetic field, in turn, can alter the magnetic characteristics of magnetic field 112 which, in turn, can alter how the magnetic union system causes objects to magnetically unite (alignment, orientation, centering, and so on). on). An electromagnet is an example of such a magnetic element whose magnetic properties can be modified as desired. Other examples include a malleable non-magnetic substrate impregnated with magnetic dopant (such as magnetite). In this way, the malleable substrate may be formed into a physical form that may affect the nature of the magnetic field produced by the magnetic doping material.

Referring now to the other aspects of the magnetic bonding system, the tight bonding feature 110 may include one or more of the magnetic elements 116r When a plurality of magnetic elements is used, the arrangement of the plurality of magnetic elements 116 may be widely varied and may interact. magnetically with a cooperating feature on another device. In one embodiment, the plurality of magnetic elements 116 associated with the firm feature 110 may help to secure at least a portion of another otherwise bonded device to the electronic device 100 by means of the bonding feature of the device 108.

At least some of the plurality of magnetic elements 116 may have a fixed size and polarity (along the lines of a single bar magnet) while the other of the plurality of magnetic elements 116 may have varying magnetic properties (such as as an electromagnet) while still another can be formed to provide specific magnetic characteristics. For example, at least one of the plurality of magnetic elements 116 may be positioned and formed (if necessary) to interact with a magnetically responsive circuitry included in the other device. Therefore, the magnetically responsive circuit may respond to the presence (or absence) of a particular magnetic element (s) of the firm feature 110. An example of the magnetically responsive circuit is described above. Hall Effect sensor 118. It should be noted that the magnetic field generated by the

Magnetic devices 116 should not extend far enough that magnetically sensitive circuits within electronic device 100 (such as Hall Effect sensor 118) are adversely affected. This is particularly important since the magnetic field is not generally contained within the housing 102 since at least a portion of the magnetic field must extend toward direção in order to interact with the magnetically active portion of the other devices. Therefore, the magnetic field at {x: y} must be limited in extent to avoid magnetically sensitive circuits, such as Hall Effect sensor 118 and compass 120. In a particular implementation, the magnetic elements of the

The joining feature of the device 108 may be grouped into distinct magnetic regions. Thus, the magnetic fields of the magnetic regions may overlap to form the magnetic field 112. The magnetic regions may include various magnetic elements which may be arranged into groups represented by magnetic elements 126 and 128. By grouping the magnetic element in separate magnetic regions, the ability of the magnetic union system to provide a magnetic field having desired characteristics can be substantially improved. The magnetic elements 126 and 128 may interact to form the magnetic field 112. In one embodiment, the interaction may take the form of the combination of magnetic properties of each of the magnetic elements 126 and 128. In some cases, the arrangement of the elements The magnetic fields 126 and 128 may be interrelated to provide the magnetic field 112 with desired characteristics. For example, the magnetic elements 126 and 128 may be arranged in such relative fashion to each other that the magnetic field 112 is antisymmetrical (or symmetrical) around a horizontal axis of the magnetic bonding feature 108. In another embodiment, the cam The magnetic field 112 may be antisymmetrical (or symmetrical) around a vertical axis of the bonding feature 108. In yet another embodiment, the magnetic field 112 may be antisymmetrical (or symmetrical) both horizontally and vertically. Figure 7A shows the electronic device 100 in close proximity.

with object 200 having the magnetic union feature 202. The magnetic union feature 202 of object 200 may include magnetic elements, each generating an individual magnetic field which may interact with the other to form a resultant magnetic field in the array. The resulting magnetic field can have magnetic characteristics (such as field strength and shape) that can interact with the magnetic field 112 of the electronic device 100 to join the electronic device 100 and the object 200 in a well-defined, precise manner. and repeatable without mechanical fasteners and without requiring external assistance. It should be noted that the magnetic field 208 may be approximately 2500 Gauss while the magnetic field 112 may be in the order of approximately 1400 Gauss when the bonding feature of device 108 is inactive. Ιλ

CTOC & JET 2OCTpocfe take many forms including accessory, peripheral, electronic device or the like. In one embodiment, the object 200 may take the form of an electronic device along the lines of the electronic device 100. Thus, the electronic device 100 and electronic device 200 may be magnetically joined together using the bonding feature of the electronic device. device 108 and magnetic bonding feature 202 to form a cooperative electronic system. The cooperative electronic system may be one in which the electronics in the electronic device 100 and corresponding electronics in the electronic device 200 cooperate with one another to perform functions that cannot be performed by either electronic device separately. In one embodiment, the information may be passed between the electronic devices 100 and 200.

More specifically, the magnetic bonding feature 202 may include at least the magnetic elements 204 and 206, each of which can generate cooperating magnetic fields to provide the magnetic field 208 (only a portion of which is shown). The properties of the magnetic field 208 may be based on the interaction of each of the plurality of the magnetic elements 204 and 206. Thus, the magnetic field 208 may have properties based on the physicalayout, relative size and magnetic polarities constituting each of the plurality of the magnetic elements. magnetic elements 204 and 206. For example, magnetic elements 204 and 206 may be arranged along a center line and have overlapping magnetic properties to provide magnetic field 208 with desired properties. The magnetic flux density B2os of magnetic field 208 of object 200 may vary as a function of the distance χ (ie, B = B2o8 (x)) of magnetic elements 204 and 206.

When object 200 takes the form of an electronic device, such as electronic device 100, then the magnetic flux density B2OS satisfies equation (1). However, when object 200 takes the form of an accessory device, then unlike the magnetic flux density B112 of the electronic device 100, which satisfies equation (1), the density of the magnetic device B2Oe (X) ^ accessory-200 can satisfy equation (2).

B2Os (x = Xi + s)> Biimiar Equation (2)

where s is the thickness of housing 212 on side 212a and X1 is the interior separation distance.

In this way, accessory device 200 can magically interact with electronic device 100 more removed from electronic device 100 than would otherwise be possible. Therefore, the accessory device 200 may be placed close to, but not necessarily contiguous with, the electronic device 100 so that the electronic device 100 and object 200 magnetically bond in a well-defined, predictable and repeatable manner.

In addition to the magnetic bonding feature 202, the accessory device 200 may further include the magnetic bonding feature 216 which may be used to interact with the tight bonding feature 110. The magnetic bonding feature 216 may include a variety of magnetically components. active. Some of the magnetic elements may take the form of magnetic elements arranged to interact cooperatively with corresponding magnetic elements in the tightly coupled feature 110. The other of the magnetic element may be more passive in nature in that they provide a mechanism for completing the magnetic element. magnetic circuit with magnetically active elements in the firm bond feature 110. An example of a magnetically passive element is a ferromagnetic material, such as iron or steel, which can interact with a magnetic element actively providing an associated magnetic field. In this way, the ferromagnetic material can interact with the magnetic field to complete a magnetic circuit between the passive element in the bonding feature 216 and the active element in the tight bonding feature 110.

Figure 7B shows that accessory device 200 can be used to provide support functions and services for electronic device 100. By allowing a portion of magnetic field 208 having magnetic flux density B2os satisfying equation (2 ) extends into the "region" 2147 ~ to the magnetically attractive force between the means of device 108 and the bonding feature of the accessory 202 can be created where the net attractive force Fits the equation (3a ) and equation (3b) r net ~ (Ltotai) ■ B2 / μ0 Equation (3a)

B / Bo = f (Xsep) Equation (3b)

where Ltotai is the total surface area of the magnetic elements B is the total magnetic flux density (B2o8 + B112) xsep is the separation distance between the magnetic elements B0 is the magnetic flux density at the surface of the regions

magnetic.

The net magnetic attraction force Fnet due to the interaction of magnetic field 208 and magnetic field 112, the bonding feature 202 can be used to activate the bonding feature of device 108. Moreover, when the bonding feature of device 108 is activated, the density of magnetic flux B112 now satisfies equation (4).

B1 i2 (x = X0 + t)> Biimiar Equation (4)

in the active state.

This increase in the magnetic flux density B112 in region 214 may result in a substantial increase in the Fiquid net magnetic attractive force between the accessory device 200 and the electronic device 100. In addition, since the Fiquid net attractive force varies with the density. of the total magnetic flux B (B20s + B112) and the flux density B in general may vary inversely with the separation distance (ie equation 3 (b)) as the electronic device 100 and the accessory device 200 approach each other. and the separation distance Xsep decreases to a limiting value consistent with the physical contact of the electronic device 100 and accessory device 200, the increase in the net attractive force Fiquida can increase markedly over a relatively short time duration. This pronounced increase in the net attractive force Fiiquida can cause devices to quickly snap into what may be referred to as "snap-in" as shown in Figure 7C showing cooperating system 300 in the form of magnetically bonded electronic device 100 in accessory device 200 It is to be noted that in a representative embodiment, the magnetic elements in the coupling facility of the device 108 may be N52 type magnets whereas the magnetic elements in the coupling feature 216 may be magnets. of type N35.

In addition, the net magnetic attractive force may be from about 10 newtons to at least 20 newtons where it may require approximately 3 newtons to activate the bonding feature of device 108.

The general Fluid magnetic attractive force between device 100 and device 200 on the coupling surface 218 can be derived as the sum of all net magnetic attractive forces Fneti for all actively coupled magnetic elements. In other words, the net magnetic attractive force generates! Fliquid satisfies equation (5).

Fnet = Equation (5)

where Fnets is the net magnetic attractive force for each of the η components. In one embodiment, the net magnetic attractive force Fneti is substantially perpendicular to that portion of the engagement surface 218 intercepted by the magnetic field 112 and magnetic field 208.

In order to ensure that the general Fluid magnetic bonding force is uniform across the engaging surface between the device 100 and the device 200, the separation distances between each corresponding magnetic element in the bonding features 108 and 202 are well controlled. The separation distance can be well controlled, for example by forming the magnetic elements to match the shape of the devices. For example, if the device 100 has a keyed (curved) housing, the magnetic elements in the device 100 may be formed to equalize the recessed shape. Further, the magnetic elements may be formed in such a way that the magnetic vectors of the corresponding magnetic elements align. In this way, the magnitude and direction of the net magnetic attractive force can be controlled as desired.

One result of the alignment of the magnetic vectors is that the direction of the net magnetic force between each magnetic element can be well controlled. In addition, by reducing the separation distance between corresponding magnetic elements to a minimum, the net attractive magnetic force Fneti between each magnetic element can be maximized.

In addition, by maintaining a substantially uniform separation distance between the various magnetic elements, a correspondingly uniform magnetic bonding force can be provided along the engaging surface 218. Moreover, by properly adjusting the corresponding magnetic vectors, Fluid can be applied normally to the coupling surface.

In addition to minimizing the separation distance between corresponding magnetic elements, the magnetic flux density between the corresponding magnetic elements can be increased by using magnetic shunts. A magnetic shunt formed of magnetically active material, such as iron or steel, may be placed on or near a magnetic element having the effect of directing the magnetic flux lines in a desired direction. Thus, for example, magnetic flux lines that would otherwise propagate in a direction away from a corresponding magnetic element may be partially redirected to a desired direction, such as to a region of magnetic union between the devices, thereby increasing the density of the general magnetic flux. Therefore, increasing the density of the available magnetic flux between the magnetic elements can result in a substantial increase in the net magnetic attractive force. Fig. 8A shows one embodiment of bonding feature 110.

In particular, the coupling facility 110 may be part of the housing 102. In particular, the coupling facility may include magnetic elements 402 which may be mounted on the edge 404 of the housing 102. The magnetic elements 402 may be widely varied. For example, magnetic elements 402 may be spatially arranged as an edge formation 404 to be used for joining and securing at least a portion of an accessory device in a particular aspect of the electronic device ΤΟΌ. For example, when the accessory device adopts the shape of a flap, the magnetic elements 402 may be used to magnetically secure the tab on the electronic device 100 to cover at least a portion of a dial. The size and shape of the formation can also be widely varied. In the embodiment shown in Fig. 8A, the formation may be rectangular and sized to encompass a substantial portion of edge 404.

Figure 8B shows a plurality of magnetic elements 410 that may be incorporated into an accessory device as part of the bonding feature 216. Some, but not all of the plurality of magnetic elements 410 may correspond with the magnetic elements 402 and be used for magnetically bonding. accessory 200 in the electronic device 100. In another embodiment, all or most of the plurality of magnetic elements 410 may be used to secure portions of the accessory device 200 to form other support structures which may be used in conjunction with each other. the electronic device 100. In one embodiment, the magnetic element 414 may be used to activate a magnetically sensitive circuit, such as the Hall Effect sensor 118.

Figures 9A - 9C show a representative magnetic bonding feature 500 according to a described embodiment. The magnetic bonding feature 500 may correspond, for example, to the bonding feature of the device 108 shown in FIG. 6 and FIGS. 7A - 7C. In the idle state, the magnetic elements within the magnetic bonding feature 500 may be positioned away from the housing 102 to minimize magnetic field lines propagating through 102. On the other hand, in the active state, the magnetic elements may move to the housing 102 in order to increase the number of magnetic field lines that propagate through housing 102, thereby satisfying equation (2).

The manner in which magnetic elements move can be widely varied. For example, magnetic elements may rotate, pivot, translate, slide or the like. In one example, the magnetic elements may be positioned within a channel that allows the magnetic elements to slide from the first position corresponding to the inactive state to a second position corresponding to the active state.

In the particular embodiment shown in FIGS. 9A-9C, the bonding feature 500 may include the magnetic element 502 having magnetic properties which may remain stable over a period of time. For example, it may be desired that the properties of the magnetic union remain stable through the expected operating duration of the electronic device 100. Thus, the magnetic field formed by the interaction of the magnetic fields of each of the magnets will also remain. stable. The stability of the magnetic field can result in a very repeatable joining process. This repeatability is particularly useful when the electronic device 100 undergoes numerous and repeated joining (joining / separating) cycles with other properly configured objects such as the accessory device 200 which requires consistently accurate placement.

In the representative embodiment shown, the magnetic element 502 may take many forms. For example, magnetic element 502 may take the form of several magnets arranged in a specific order and configuration having stable magnetic properties (such as polarity and intrinsic magnetic intensity). However, in order to satisfy equation (1) when magnetic bonding feature 500 is inactive, magnetic element 502 must remain at least a distance χ = (x0 + t) from outside housing 102. In other words In order to satisfy equation (1), the dimensions of the bonding feature of device 500 need to consider at least the magnetic properties and physical layout of the magnetic element 502.

In this way, the magnetic element 502 can be attached to the retention mechanism 504 arranged to exert the retention force. Retention · The retention force Fretention can be used to retain the magnetic element 502 in a position within the bonding feature of the device. 500 resulting in little or no leakage of the magnetic flux outside the TOO electronic device (ie, equation (1) ~ is satisfied) when device 500 recursion is not idle. In one embodiment, the retention mechanism 504 may take the form of a spring arranged to provide the retention force Fretention according to equation (6): Fretention = κ. Δχ Equation (6)

where κ is the spring constant of the retention mechanism 504 and Δχ is the spring displacement from equilibrium. For example, Figure 9B shows representative magnetic bonding feature 500 in an active state. By the proper configuration of the magnetic element 502 and those in the accessory bonding feature 204, the magnetic interaction resulting from the magnetic field of the magnetic element 502 and that generated by the accessory bonding feature 204 can create a net attractive magnetic force at least as large as that is required to activate the magnetic bonding feature 500. In other words, the net attractive magnetic force can be at least as great as that of the Fact activation force that satisfies equation (7), thereby exceeding the retention force. causing the magnetic element 502 to move from the inactive position (ie χ = 0) to the active position (ie χ = x0), Fact> Fretention (Δχ = x0) Equation (7).

However, only another magnetic union feature that generates

A magnetic field having properties that "match" the magnetic field properties of the magnetic element 502 may activate the magnetic bonding feature 500. Therefore, as shown in Figure 9C, the presence of the object 506 formed of the magnetically active material (such as located on the outer surface of housing 102 (ie, χ = X0 + t) cannot activate magnetic bonding feature 500. More specifically, in one embodiment, the net magnetic attractive force generated between object 506 and the Magnetic bonding feature 500 is less than 2 NT1 while the Fact activation force can be in the order of approximately 3 NT. More specifically, in order to transition from the idle state to the

active, the magnetic force created between magnetic element 502 and object 506 must be greater than the activation force Fact · However, since the magnetic flux density of the magnetic field generating magnetic element 502 on the outer surface of housing 102 is lower than Bnary, any magnetic force generated between object 506 and magnetic element 502 is substantially smaller than Fretero and therefore fails to satisfy equation (7). Therefore, magnetic element 502 remains fixed in place at approximately X = O and magnetic bonding feature 500 cannot transition from idle to active state.

It should be noted that the spring can be widely varied. For example, it may vary depending on the type of movement. Examples include tension, compression, twisting, sheets and the like. In a particular implementation, leaf springs are used.

It should also be noted that in some embodiments, the magnetic element 502 may be fixed in such a way that no spring is required. In these embodiments, although equation (1) may not be satisfied, it may nevertheless be a practical disposition.

Fig. 10 shows an embodiment of the bonding feature of the device 600 according to one embodiment of the present invention. Bonding feature 600 may correspond with member 208 in FIG. 6 and FIGS. 7A-7C. This embodiment is similar to the embodiment shown in Figures 9A - 9C, except that instead of a single mechanism, multiple mechanisms and more particularly a pair of mechanisms in the form of magnetic element 602 and magnetic element 604 are used. In particular, Figure 10 shows the bonding feature of device 600 in the active state. More specifically, the spring 606 joined to the magnetic element 602 and the spring 608 joined to the magnetic element 604 are each extended by the distance Δχ.

In this system, the two mechanisms cooperate to form the magnetic field. They can move independently or they can be connected and move as a unit. Spring forces and magnetic forces may vary. For example, the system may be symmetrical or asymmetrical. The arrangement of the magnetic elements may be similar or different. Again being symmetrical or asymmetrical. Configuration may depend on system needs. The magnetic union system can adopt many enhancements, one of which provides a repeatable and precise magnetic union mechanism that can be used to join multiple properly configured objects.

Figures 11A-11B show a specific implementation of the

device coupling feature 108 in the form of device coupling feature 700 according to one embodiment. The bonding feature of the device may correspond with the element 108 shown in Fig. 6 and Figs. 7A - 7C. In some cases, the device 700 bonding feature may be used.

together with the springs 606 and 608 as shown in figure 10. As shown in figure 11A, the coupling feature of the device 700. In particular,

The bonding feature of device 700 is shown in idle state having magnetic elements in the form of magnetic assembly 702 which may be contained within a housing. In this way, a retention mechanism

(not shown) bonded to magnet assembly 702 can exert associated retention force Fretention · Retention force Fretention can be used to hold magnet assembly 702 in a position consistent with the bonding capability of device 700 being in inactive state (that is, satisfying equation (1)).

Magnetic assembly 702 may each include individual magnets.

wow. In the embodiment described, the individual magnets may be arranged in a structure in which the polarities of the magnets may be oriented to form a coded magnetic structure. The encoded magnetic structure may be formed of a sequence of magnetic polarities and in some

Magnetic intensity cases. In other words, the sequence of magnetic polarities can be represented, for example, as {+1, +1, -1, +1, -

1 τ 1, -1, -1}. For this particular example, "+1" indicates the direction and intensity of the magnet. Therefore, a positive "+" sign may indicate that the corresponding magnet is aligned having a magnetic vector in a particular direction.

However, a negative sign '-' may indicate a magnetic vector in the opposite direction and '1' indicates the intensity of a unit magnet.

When a plurality of magnets of the same polarity are placed

each next to each other, the magnetic fields of each of the plurality of magnets may combine, such that the plurality of magnets may be considered equivalent to a single magnet, the only magnet having the combined properties of the plurality of magnets. For example, the coded magnetic sequence {+1, +1, -1, +1, -1, +1, -1, -1} representing eight individual magnets can be considered equivalent with the coded magnetic sequence {+2 , -1, +1, -1, +1, -2} personified as a formation of six individual magnets. In one embodiment, the magnets in a first and last position may have the same magnetic intensity as the other magnets in the formation, twice their respective size. On the other hand, the magnets in the first and last position may be about the same size as the other magnets, but twice the magnetic intensity of the other magnets. In any case, equivalence of magnetic properties can provide a more compact coded sequence of magnets. The smaller size can help reduce weight as well as preserve the amount of valuable internal real estate needed to house the magnetic bonding feature. In addition, since magnetic flux density is directly related to this area through which magnetic field lines propagate, when the area through which a given magnetic flux propagates decreases, the resulting magnetic flux density increases.

In one embodiment, the magnet assembly 702 may include individual magnets 712a, 712b, and 712c having relative sizes of 2L, 1L, and 1L, respectively, where "L" represents a unit length. It should be noted that as discussed above, a magnet having a relative size of "2L" may be embodied as a single magnet having a physical length of "2L", two side by side magnets, each having a length of "1L". with the magnetic poles aligned with each other, or a magnet of unit length L having twice the magnetic intensity of the other magnets. Thus, for the remainder of this discussion, with respect to the terms 2L and 1L, "L" may represent a unit length and the relative intensity of the magnet may be represented by the associated digit. For example, a magnet having a Theoretical Magnetic Intensity of-uT ', but a L-Compressto' may be considered equivalent to a magnet having a relative intensity of '2' and a length of '1L'. Both relative magnetic intensity and orientation can be used to form the encoded magnetic structure.

For example, magnet 712a may have an overall length of approximately twice that of magnets 712b or 712c. On the other hand, magnet 712a may be the same length as magnets 712b and 712c, but have an inherent magnetic intensity twice that of magnets 712b and 712c. In yet another embodiment, magnet 712a may be an equivalent magnet formed of two (or more) constituent magnets having their respective polarities aligned.

In one embodiment, magnets 712a, b, c may be separated from each other by a predetermined distance. For example, in an implementation, the magnets may be spaced equidistant from each other. This spacing is naturally based on the desired magnetic properties of the generated magnetic field. In another embodiment, these magnets having anti-aligned polarities may be magnetically joined together. In this way, the magnetic bond formed between the adjacent magnets can be used to maintain the sequence integrity of the magnets in the magnetic assembly. However, these magnets having aligned polarities need to be held together by an externally applied force to overcome the repulsive magnetic force generated between the two aligned magnets.

In addition to size and placement, the magnetic polarities of magnets 712a, b, c can be selected based on the desired properties of the generated magnetic field. In the embodiment shown, however, the magnetic elements are magnetically coupled to each other end-to-end, thereby reducing the amount of space required and increasing the density of the magnetic flux by reducing the general region in which the magnetic field lines are propagated. .

In particular, the magnetic array 702 may have a specific magnetic polarity pattern set in which each of the magnets 712a, b and c are oriented "in such a way that their N or S" "pots" are aligned (or For example, the magnets in magnetic assembly 702 may be arranged to form the first encoded magnetic structure {+1, -1, +1} in which the magnetic poles of magnets 712a, b, c are aligned according to the first magnetic polarity standard (P1, P2, P1} by which it is intended that the magnetic pole of magnet 712a will be anti-aligned with magnet 712b, which in turn is anti-aligned with magnet 712c.

Magnetic assembly 702 may also include individual magnets 714a, b, c and have relative sizes of 1L, 1L and 2L, respectively. In addition, magnets 714a, b, c may be arranged to have their respective magnetic poles aligned according to the second magnetic polarity pattern {P2, P1, P2} which is the inverse (or complement) of the first pattern. of magnetic polarity {P1, P2, P1}. In terms of the encoded magnetic structure, magnets 714a, b, c can be aligned according to the second encoded magnetic sequence {-1, +1, -1} which is the inverse or complement of the first structure. magnetic encoded {+1, -1, +1}. This antisymmetric relationship between magnets 712a, b, c and 714a, b, c provides a magnetic field that is antisymmetric with respect to the centerline 716. Figures 11A and 11B also show a specific implementation.

accessory coupling feature 800 which may, for example, correspond to element 202 shown in FIG. 6 and FIGS. 7A-7C. Magnetic assemblies 802 may include various magnetic elements. The magnetic elements may be arranged in such a way that the combined magnetic field equals the magnetic field of the magnetic assembly 702.

The 802 magnet assembly may include 802a, 802b, and 802c magnets, each being approximately the same size as the corresponding magnet 712a, 712b, and 712c in the 702 magnet assembly. However, in order to maximize the net attraction force Fnet and driving the magnetic interaction between the magnetic fields to the desired equilibrium, magnets 802a, b, c are aligned based on the second magnetic polarity pattern {P2, P1, P2}. Magnetic assembly 802 may also include magnets 804a, 804b and üU4c, each being approximately the same size as corresponding magnets 714a, 714b and 714c. In addition, according to the general objective of the magnetic interaction between the magnetic fields for equilibrium in the desired device configuration, magnets 804a, b, c can be aligned according to the first magnetic polarity pattern { P1, P2, P1}.

Figure 11B shows the bonding feature of device 700 in the active state due to the magnetic interaction between the magnetic assemblies 702 and 802. In particular, as long as the arrangement of the magnetic elements between the bonding feature 700 and these in the feature accessory bond 800 "equals", then the magnetic interaction between the magnetic fields can induce the movement of the magnetic assemblies 702 from the inactive state (ie, χ = 0) to the active state (that is, χ = x0).

Figure 12 illustrates a sequence of shifting positions relative to the magnetic structure of the magnetic assembly 702 and the complementary magnet structure of the magnetic assembly 802. The magnetic assembly 702 is shown as encoded with the encoded magnetic sequence {+2, - 1, +1, -1, +1, -2}. Magnetic array 802 is shown as encoded with the complementary encoded magnetic sequence {-2, +1, -1, +1, -1, +2}. For this example, the magnets may have the same or substantially the same magnetic field strength (or amplitude) as for the purpose of this example is provided a unit of 1 (where A = attraction, R = repulsion, A = -R, A = 1, R = -1). In this example, the magnetic assemblies 702 and 802 are moved relative to each other by "1L" in length at a time (note that the antisymmetry around the 716 axis of the encoded magnetic sequence allows the results of a shift to reflect the results of a right shift, so only a right shift is shown).

For each relative alignment, the number of repelling magnets plus the number of attracting magnets are calculated, where each alignment has a total force according to a function of the magnetic force based on the magnetic field intensities of the magnets. In other words, the "total magnetic torque between the first and second frog structures" can be determined as the sum from left to right along the structure of the individual forces at each magnet position, of each magnet or pair of magnets interacting with their directly opposite magnet in the opposite magnet structure. Where only one magnet exists, the corresponding magnet is zero and the force is zero. Where two magnets exist, the force is R for poles equal or A for opposite poles for each unit magnet.

The total magnetic force can be calculated for each of the figures and shown with each figure along with the relative change value. Thus, the use of a specific coded magnetic sequence {+2, - 1, +1, -1, +1, -2} may result in the net magnetic attractive force Fnet ranging from -3 (ie 3R). to +8 (ie + 8A) where the peak occurs when magnetic assemblies 702 and 802 are aligned such that their respective codes are also aligned. It should be noted that the free net magnetic force of the peak can range from -3 to +4. As such, the net magnetic force can cause magnetic assemblies 702 to usually repeat unless they are aligned, such that each of their magnets is correlated with a complementary magnet (that is, a south pole of the magnet aligns with another north pole of the magnet or vice versa). In other words, magnetic assemblies 702 and 802 correlate highly when they are aligned so that they substantially reflect each other.

It should also be noted that when the magnetic assemblies 702 and 802 are 180 ° out of phase (ie somewhat similar as the misalignment of top to bottom also referred to as upside down) the net magnetic force generated can be of the order of 8R. It is therefore highly unlikely that devices being magnetically bonded together using magnetic assemblies 702 and 802 will be joined upside down.

Figure 13 illustrates the graph 900 of the Fluid (L) function. The Leak function (L) describes the Net magnetic force Fluid as a function of the shift (L) of the change shown in Figure 12 for magnet structures encoded in magnetic assembly 702 and magnetic assembly 802. It should be noted that the symmetrical nature of magnetic structures encoded in the magnetic assemblies 702 and 802 around the 716 center line proves that the Fuquida (L) function is also antisymmetric around the 716 centerline. Thus, the results of figure 12 can be marked on the right side of the 716 and reflected around the 716 centerline to fill the left side of chart 900.

As shown in Fig. 13, the Fluid (L) function has a global maximum value when the magnetic assemblies 702 and 802 correlate in a position corresponding to the centerline 716. In other words, the Fluid function (L = 0) reaches a maximum (i.e. 8A) when all magnetic elements in magnetic assemblies 702 and 802 having opposite polarities align. Any other configuration (that is, Fuchida (L ^ O) results in the Net Fluid magnetic force being less than the global maximum value (8A). It should also be noted, however, that the Fluid function (L) has at least minus two local maximum values (ie, Fluid (L = ± 3)) that allows for a weak union between magnetic assemblies 702 and 802. However, a strong durable union can only occur when the magnetic bonding feature of device 700 associated with the magnetic assembly 702 is properly activated, so by establishing the activation force FAct that satisfies equation (8), a "false activation" of the magnetic bonding feature of device 700 or a weak union between the magnetic assemblies 702 and 802 can be avoided.

Flaccid (L = local maximum) <FAct ^ Fliquid (L = global maximum) Equation (8).

It should also be noted that the activation force FAct is

related to retention force Fretention through equation (6). Thus, equation (6) and equation (8) in view of the Fluid function (L) can be used to determine an appropriate value for spring constant k.

Figures 14 and 15 show other modalities where the

Magnetic instruments can be arranged vertically and horizontally. In addition, the magnetic elements may be sized to have polarities that also extend both horizontally and vertically. For example, arrangement 1000 shows two lines of magnetic elements where each magnetic element extends height H in the vertical direction. In the arrangement shown, each vertically disposed magnetic element has the same magnetic polarity forming the equivalent magnetic structure 1002. In other words, both array 1000 and array 1002 can both be characterized as having the coded magnetic sequence {+ 2, - 2 + 2 -2 + 2, 2}.

Figure 15 shows a top view of the magnetic formation configured as a two-dimensional coded magnetic sequence 1004 according to the described embodiments. The two-dimensional coded magnetic sequence 1004 can be used to extend the combined magnetic field over an area that extends in both χ and y directions. This extended area may result in an overall increase in the area available to propagate magnetic field lines which may result in an increase in magnetic flux and a proportional increase in net magnetic attractive force. In addition to providing an improved magnetic union, the two-dimensional encoded magnetic sequence 1004 can approximate non-integer values of magnetic properties such as magnetic intensity. For example, with the magnetic array 1004, the magnetic fields of the various components may combine to approximate the encoded magnetic sequence {+ 1.5, -1.5, + 1.5, -1.5, + 1.5. , -1.5}. In addition, a two-dimensional coded magnetic sequence 1004 can assist in providing vertical alignment as well as horizontal alignment. For the remainder of this discussion, various modalities of

Accessory 200 are discussed.

In one embodiment, the accessory device 200 may include various protective elements that may be used to protect certain aspects of the electronic device 100. For example, the accessory device 200 may take the form of a protective cover. The protective cover may include a flap hingedly connected to a hinge assembly. The hinge assembly can be coupled in turn to the electronic device 100 by means of accessory coupling feature 202. In this way, the flap portion can be used as a protective cover to protect aspects of the device. 100, such as a dial. The flap may be formed of various materials such as plastic, cloth and so on. The flap may be segmented in such a way that a flap segment may be raised to expose a corresponding portion of the dial. The tab may also include a functional element that may cooperate with a corresponding functional element in the electronic device 100. Thus, manipulation of the tab may result in a change in the operation of the electronic device 100.

The flap may include magnetic material that may be used to activate a magnetically sensitive circuit in the electronic device 100 based, for example, on the Hall Effect. The magnetically sensitive circuit can respond by generating a signal that can be used in turn to change the operating state of the electronic device 100. Since the cover can be easily attached directly to the tablet-free device housing, the cover may essentially match the shape of the electronic device 100. In this way, the cover will not detract from or otherwise obscure the appearance and impression of the electronic device 100.

In one embodiment, the accessory device 200 may be used to enhance the overall functionality of the electronic device 100. For example, the accessory device 200 may be configured to act as a suspending apparatus. When magnetically bonded to the electronic device 100, the accessory device 200 can be used to suspend the electronic device 100. In this way, the electronic device 100 can be used as a display for displaying visual content such as art, movies. , photos, and so on on a wall or suspended from a ceiling. As a hanging device, accessory device 200 may be used to suspend electronic device 100 from a wall or ceiling. The electronic device 100 can be easily removed by simply exerting sufficient release force to overcome the attractive magnetic force Kíqlhda · The accessory device 200 pocfe can be left tto-iagar and be used to re-connect the electronic device 100 ( or other device) at a later time.

In one embodiment, the accessory device 200 may also take the form of a clamping mechanism for joining objects which are not themselves equipped to magnetically bond to the electronic device 100. For example, the accessory device 200 may be configured to carry a pen or other such input device. The pen can be used to provide input to the electronic device. In some cases, accessory device 200 may provide a signal to electronic device 100 indicating the presence of the pen. The signal may cause the electronic device 100 to enter a pen recognition state, for example. More particularly, when the accessory device 200 is magnetically bonded to the electronic device 100, the electronic device 100 may activate the pen input state in order to recognize pen type inputs. When the accessory device 200 is removed, the electronic device 100 may disable the pen input state. In this way, the pen can be conveniently attached / detached from the electronic device 100 when required. Accessory device 200 may take the form of a stand

which can be used to increase the functionality of the electronic device 100. For example, the accessory device 200 can be configured to act as a dial platform on which an electronic device 100 display can be viewed at a comfortable viewing angle ta! as 75 °. In other words, when placed on a horizontal surface, such as a table or desk, the accessory device 200 may support the electronic device 100 in such a way that the visual content shown on the dial can be viewed at approximately a viewing angle of approximately 75 °. The accessory device 200 may also take the form of a

support that can be used to increase the functionality of the electronic device 100 in a keyboard state. In the keyboard state, the zuu accessory device can be used to display a touch screen at an angle that is ergonomically suitable. In this way, touch input events can be applied (on a virtual keyboard, for example) to a keyboard. angle that does not overload the user's wrist, hands, arms, etc.

The remainder of this discussion will describe particular embodiments of devices that may use the magnetic union system. In particular, Figure 16A and Figure 16B show the electronic device 100 shown in terms of the tablet device 1100 and the accessory device 200 is shown as the cover assembly 1200, each in top views in perspective. These elements may generally correspond to any of these previously mentioned. In particular, Figures 16A and 16B show two perspective views of flatbed device 1100 and cover assembly 1200 in the open configuration. For example, Figure 16A shows the bonding feature of the device 108 included in the tablet device 1100 and its relationship to the tablet device 1100. Figure 16B, on the other hand, is the view shown in figure 16A is rotated approximately 180 ° to provide a second view of the joint feature 202 and its relationship to the cover assembly 1200.

The tablet 1100 can take the form of a tablet computing device, such as the iPad ™ manufactured by Apple Inc. of Cupertino, CA. Referring now to Figure 16A, the tablet device 1100 may include the housing 1102 which may surround and support the bonding feature of the device 108. In order not to interfere with the magnetic field generated by the bonding feature of the device 108, by at least that portion of housing 1102 closest to the bonding feature of device 108 may be formed of any number of non-magnetic materials, such as plastic or non-magnetic metal, such as aluminum. The housing 1102 may also internally engage and support various structural and electrical components (including integrated circuit pads and other circuit assemblies) to provide computing operations for the 1100 digitizing tablet device. The housing 1102 may include the opening 1104 for placing the internal components and may be sized to accommodate a suitable display assembly or system for providing a user with at least visual content such as through a dial. In some cases, the dial assembly may include touch capabilities providing the user with the ability to produce tactile inputs on the tablet device 1100 using touch inputs. The display assembly may be formed of several layers including a higher layer taking the form of clear cover glass 1106 formed of polycarbonate or other suitable plastic or highly polished glass. Using highly polished glass, the cover glass 1106 can adopt the cover glass form 1106 substantially filling the opening 1104.

Although not shown, the dial glass underlying the 1106 cover glass can be used to display images using any suitable display technology such as LCD, LED, OLED, electronics or e-inks, and so on. The dial assembly can be placed and secured within the cavity using a variety of mechanisms. In one embodiment, the dial assembly is fitted into the cavity. It can be placed flush with the adjacent portion of the housing. This way, the display can display visual content that may include visual, still images, as well as icons such as the graphical user interface (GUI) that can provide information to the user (eg text, objects, graphics). , as well as receive input provided by the user. In some cases, displayed icons may be moved by a user to a more convenient location on the display.

In some embodiments, a face mask may be applied to or incorporated into or under the cover glass 1106. The face mask may be used to accentuate an unmasked portion of the face used to display visual content and can be used to make the binding feature of device 108 and the binding feature 110 less obvious. The digitized tablet device may include several ports that can be used to pass information between the tablet device 1100 and the external environment. In particular, data port 1108 can facilitate data transfer and power while speakers 1110 can be used to produce audio content. Home button 1112 can be used to provide an input signal that can be used by a processor included in the 1100 tablet device. The processor can use home button signal 1112 to change the operating state of the tablet device. 1100. For example, the home button 1112 can be used to restore a currently active page displayed by the display assembly.

In one embodiment, the accessory device 200 may take the form of the cover assembly 1200. The cover assembly 1200 may have a look and feel that complements those of the tablet 1100 by adding to the overall look and feel of the tablet device. 1100. The cover assembly 1200 is shown in Figures 16A and 16B joined to the tablet device 1100 in an open configuration in which the cover glass 1106 is fully visible. Cover assembly 1200 may include flap 1202. In one embodiment, flap 1202 may be of a size and shape according to the cover glass 1106. Flap 1202 may be pivotally connected to accessory coupling feature 202 by means of a hinge assembly (not shown). The magnetic bonding force between the bonding feature 202 and the bonding feature of the device 108 may hold the cover assembly 1200 and the tablet device 1100 in an appropriate orientation and placement opposite the cover 1202 and cover glass 1106. By proper orientation, it is intended that the cover assembly 1200 can only properly attach to the flatbed device 1100 with the tab 1202 and cover glass 1106 aligned in a corresponding engagement. The corresponding arrangement between cover glass 1106 and flap 1202 is such that flap 1202 substantially covers all cover glass 1106 when flap 1202 is brought into contact with cover glass ΤΤ06 as shown in Figure 17A below.

Figures 17A and 17B show cover assembly 1200 and tablet device 1100 magnetically joined together. Figure 17A shows a closed configuration in which cover glass 1106 is fully covered by and in contact with tab 1202. Cover assembly 1200 may pivot around the hinge assembly 1204 of the closed configuration of figure 17A for an open configuration. of figure 17B. In the closed configuration, the inner layer 1206 of the cover assembly 1200 may be in direct contact with the cover glass 1106. In one embodiment, the inner layer 1206 may be formed of material that can passively clean the cover glass 1106. Passive cleaning by the inner layer 1206 of the cover glass 1106 may be accomplished by moving these portions of the inner layer 1206 in contact with the cover glass 1106. In a particular embodiment, the inner layer 1206 may be formed of a composite material. microfiber.

In order to transition from the closed to the open configuration, the Wiring release force can be applied to tab 1202. The Füberation release force can overcome the attractive magnetic force between coupling feature 216 on tab 1202 and coupling feature 110 on For this reason, cover assembly 1200 can be attached to the tablet device 1100 until the Füberation release force is applied to tab 1202. In this way, tab 1202 can be used to protect the cover glass 1106. For example, the cover assembly 1200 may be magnetically bonded to the tablet device 1100. The tab 1202 may then be placed over and magnetically fastened to the cover glass 1106 by the magnetic interaction between the features. 1102 and 216. The tab 1202 can be separated from the cover glass 1106 by applying the Füberation release force directly to the tab 1202. A f release budget Füberation can overcome the magnetic attraction between magnetic union features 110 and 216. Therefore, flap 1202 can then move away from the glass of unobstructed cover 1106.

In order to maintain a good magnetic union between flap 1202 and magnetic bonding feature 110, flap 1202 may include various magnetic elements. Some of the magnetic elements in tab 1202 may interact with corresponding magnetic elements in magnetic bonding feature 110. The net magnetic attractive force generated between the magnetic elements may be strong enough to prevent inadvertent release of tab 1202 from cover glass 1106. during normal handling. The net magnetic attractive force, however, can be surpassed by the release force.

Figure 18 shows a top view of a specific embodiment of cover assembly 1200 in the form of segmented cover assembly 1300. Segmented cover assembly 1300 may include body 1302. Body 1302 may have a size and shape according to with the cover glass 1106 of the tablet 1100. The body 1302 may be formed from a single piece of folding or flexible material. The body 1302 may also be divided into segments separated from each other by a folding region. In this way the segments can be bent with respect to one another in the folding regions. In one embodiment, body 1302 may be formed of layers of material joined together forming a laminated structure. Each layer may take the form of a single piece of material which may have a size and shape in accordance with body 1302. Each layer may also have a size and shape which correspond to only a portion of body 1302. For example, A layer of rigid or semi-rigid material of approximately the same size and shape as a segment may be joined to or otherwise associated with the segment. In another example, a layer of rigid or semi-rigid material having a size and shape according to body 1302 may be used to provide segmented cover assembly 1300 as an assembly with a resilient foundation. It should be noted that the layers may each be formed of materials having desired properties. For example, a layer of segmented cover assembly 1300 that contacts delicate surfaces, such as glass, may be formed of a soft material that will ruin or otherwise damage the delicate surface. In another embodiment, a material such as microfiber may be used that can passively clean the delicate surface. On the other hand, a layer exposed to the external environment may be formed of a more robust and durable material such as plastic or leather.

In a specific embodiment, segmented body 1302 may be

be divided into several segments 1304 - 1310 interspersed with thinner foldable portions 1312. Each of segments 1304 - 1310 may include one or more inserts disposed therein. By way of example, the segments may include a cavity region where the inserts are placed or alternatively the inserts may be embedded in the segments (e.g. insert molding). If cavities are used, the cavity region may have a size and shape to accommodate the corresponding inserts. The inserts may have various shapes, but are more typically shaped to match the overall appearance of segmented body 1302 (e.g., rectangular). The inserts may be used to provide structural support for the segmented body 1302. That is, the inserts may provide hardness to the cover assembly. In some cases, the inserts may be cited as hardeners. As such, the cover assembly is relatively rigid, except along the thinner foldable regions that do not include the inserts (e.g., allows folding) making the segmented cover assembly 1300 more robust and easier to handle. . In one embodiment, segments 1304, 1306, and 1310 may be related to segment 1308 in size in the ratio of approximately 0.72 to 1 meaning segments 1304, 1306, and 1310 are sized in width to be approximately 72% of width. 1308. In this way, a triangle having appropriate angles can be formed (ie approximately 75% for the dial pad and approximately 11% for the pad pad discussed below).

Segments 1306, 1308, and 1310 may include inserts 1314, 1316, and 1318, respectively (shown as dotted lines). The inserts 1314-1318 may be formed of rigid or semi-rigid material by adding resilience to the body 1302. Examples of materials that may be used include plastics, fiberglass, carbon fiber composites, metals and so on. Segment 1304 may include insert 1320 also formed of resilient material, such as plastic, but also arranged to accommodate magnetic elements 1322, some of which may interact with magnetic elements in tablet device 1100 and more specifically joining feature 110.

Because of the ability of the segmented body 1302 to bend and more particularly the various segments to bend relative to each other, most of the magnetic elements 1322 can be used to interact magnetically with the magnetically active insert 1324 embedded in insert 1318. By magnetic bonding From both the active insert 1324 and the magnetic elements 1322, various support structures may be formed, some of which may be triangular in shape. Triangular support structures may assist in the use of the tablet device 1100. For example, a triangular support structure may be used to support the tablet device 1100 in such a way that visual content may be presented at an angle. approximately 75 ° from the horizontal. However, in order to be able to properly fold segmented coverage 1300, segment 1308 may be sized to be slightly larger than segments 1304, 1306, and 1310 (which are generally the same size). In this way, segments can form a triangle having two equal sides and a third longer side, the triangle having an interior angle of approximately 75 °.

An attempt to form at least one support structure

The triangular shape may include folding of segment 1304 with respect to segments 1306 - 1310 in such a way that most of the magnetic elements 1322 embedded in insert 1320 magnetically attract magnetically active insert 1324. Thus segment 1304 and segment 1310 may be magnetically joined forming a triangular support structure having the appropriate dimensions. The triangular support structure can be used as a platform on which the HOO tablet device can be placed such that the visual content can be displayed at approximately 75 °. In another example, the segmented cover 1300 may be folded to form a triangular support structure that may be used as a keyboard support. The segmented cover 1300 may also be folded to form a triangular support structure that may be used to suspend the flatbed device 1100 from a horizontal support part (such as a ceiling) or a support part. vertical (such as a wall).

Cover assembly 1300 may pivotally join to accessory coupling feature 202 by means of a hinge assembly. The hinge assembly may provide one or more pivots to allow the cover to fold over the device while the cover assembly is attached to the device through the magnets. In the embodiment illustrated, the hinge assembly may include first hinge portion (also referred to as first end ear) 1328 and a second hinge (or second end ear) portion 1330 disposed opposite the first end ear. The first end-ear 1328 may be rigidly connected to the second end-ear 1330 by means of the connecting rod 1332 (shown in dotted line form) incorporated into a tubular portion of the segmented body 1302. The longitudinal geometrical axis of the connecting rod 1332 may be act as pivot line 1333 around which the segmented body can pivot relative to the hinge assembly. The connecting rod 1332 may be formed of metal or plastic strong enough to rigidly support the cover assembly 1300 as well as any objects such as the tablet device 1100 magnetically bonded to the magnetic bonding feature 202. .

In order to prevent metal to metal contact, the first end ears 1328 and the second end ears 1330 may each have protective layers 1336 and 1338 respectively joined thereto. Protective layers (also referred to as shock absorbers) 1336 and 1338 may prevent direct contact between first end ear 1328 and second end ear 1330 with housing 1102. This is particularly important when end ears 1328, 1330 "and housing 1102 are formed of metal.The presence of dampers 1336 and 1338 may prevent metal to metal contact between the end ears and housing 1102, thereby eliminating the chance of substantial wear and tear at the contact point may degrade the overall look and feel of the 1100 tablet device.

In order to maintain their protective qualities, the 1336 and 1338 dampers may be formed of material that is resilient, durable, and resists disfiguring the exterior surface finish of the 1100 tablet device. This is particularly important due to the close tolerances required for a good magnetic bonding and the number of bonding cycles expected during the operating life of the 1100 tablet device. In this way, the dampers 1336 and 1338 can be formed of soft plastic, cloth or paper that can be attached to the end ears using any proper adhesive. It should also be noted that in some cases the dampers may be removed and replaced with new dampers as needed.

The first end ear 1328 and the second end ear 1330 may be magnetically connected to the electronic device by extending the hinge 1340 which is configured to pivot relative to the end ears. The hinge can be made using hinge columns 1342 (a portion of which may be exposed). The hinge columns 1342 may rotatably secure the hinge extension 1340 to both the first end ear 1328 and the second end ear 1330. The hinge extension 1304 may include magnetic elements. The magnetic elements may be arranged to magnetically join the extension of the hinge 1340 into a magnetic union feature having an associated arrangement of magnetic elements in the electronic device. In order to secure the magnetic elements in place within the hinge extension 1340, hinge columns 1342 may be used to secure the magnetic elements located at both ends of the hinge extension 1340 reducing the likelihood that the magnetic elements will not overflow. ~ H340 of the hinge move continuously having the potential to disrupt the magnetic union between the extension of the hinge 1340 and the magnetic union feature in the electronic device.

In order to ensure that there is no interference between the elements

In the magnetic hinge extension 1340 and the corresponding magnetic elements in the electronic device, the hinge extension 1340 may be formed of magnetically inactive material, such as plastic or non-magnetic metal, such as aluminum. When the extension of the hinge 1340 is formed of magnetically inactive metal, such as aluminum, metal-to-metal contact between the extension of the hinge 1340 and the housing 1102 of the electronic device 1100 may be prevented by the use of the protective layer 1344. The protective layer 1344 may be applied to the surface of the hinge extension 1340 facing the housing 1102 when the hinge extension 1340 and the electronic device 1100 are magnetically joined together. Protective layer 1344 (also referred to as label 1344) may be formed of many materials that will not ruin the finish of housing 1102. Such materials may include, for example, paper, cloth, plastic and so on. Figures 19A and 19B show a more detailed view of the

two embodiments of hinge extension 1340. More specifically, Figure 19A shows hinge extension mode 1400 where magnetically inert spacers are used to separate and secure the magnetic elements. In particular, the extension of the hinge 1400 may surround and support the magnetic elements 1402 used by the magnetic bonding feature 202 to magnetically join the segmented cover assembly 1300 to the tablet device 1100. The magnetic elements 1402 may be arranged. in a specific configuration that equals matching magnetic elements in the device 108 bonding feature on the tablet device 1100. In this way, the segmented cover assembly 1300 and the tablet device 1100 can be joined precisely and repeatedly. In order to maintain the repeatable magnetic coupling over an extended period of time, the magnetic elements 1402 may remain in a stable configuration. In other words, the magnetic elements 1402 in the extension of the hinge 1400 must remain in their relative positions and polarities in front of the corresponding magnetic elements in the magnetic tablet system 1100 for an extended period of time, this is particularly important. when repeated joining cycles are expected to occur over an expected operating life of cover assembly 1300 and / or tablet 1100.

Therefore, to ensure the integrity of the magnetic coupling over the course of many bonding cycles, the configuration of the magnetic elements 1402 may remain essentially fixed with respect to each other and the corresponding magnetic elements in the bonding feature of the device. 108. Therefore, in order to ensure that the physical outlet of the magnetic elements 1402 remains essentially fixed, filler 1404 may be inserted between the various magnetic elements to the extent of the hinge 1400. Filler 1404 may be be non-magnetic material such as plastic. The filler 1404 may be formed to fit tightly into the gaps between the magnetic elements. In this way, the magnetic elements 1402 remain in a fixed and stable configuration for an extended period of time.

On the other hand, Figure 19B shows another embodiment of the hinge extension 1340 in the form of the hinge extension 1410 which utilizes the mutual magnetic attraction between the physically adjoining magnetic elements to hold the magnetic elements in place. This reduces the number of component parts. In addition, due to the reduced area absorbed by the magnetic elements 1402, the corresponding magnetic flux density may be increased. However, end caps 1412 may be used to secure these magnetic elements located at either end of the hinge extension 1410. End caps 1412 may be required to overcome a liquid magnetic repulsive twist when the magnetic elements at either end of the extension. of hinge 1410 have aligned polarities. In addition to the end caps 1412, an alternative embodiment may provide the centrally located spacer 1414. The centrally located spacer 1414 may be formed of magnetically inert material and may be used to secure the magnetic elements 1402 in place.

Figure 19C shows that portion of the hinge extension 1340 forming part of the engaging surface when the segmented cover assembly 1300 is magnetically bonded to the flatbed device 1100. In particular, label 1344 is shown attached to the hinge extension. 1340 using adhesive such as glue. It should be noted that label 1344 is arranged to match the shape of that portion of housing 1102 which also forms part of the engaging surface. In this way, the separation distance between corresponding magnetic elements can be minimized.

Figure 20A shows a representative side view of magnetically segmented cover assembly 1300 on digitizer device 1100. Figure 20B shows representative cross-sectional views of segmented cover assembly 1300 / digitizer table 1100 along line AA shown in Figure 18. Figure 20B shows a covered configuration and Figure 20C shows a folded back configuration that fully exposes the protective layer 1106 of the tablet device 1100.

Figure 21A shows a sectional side view 1500 of the extension of the magnetically joined hinge 1340 in the housing 1102 having a curved shape. In such an embodiment, the housing 1102 may have a curved shape and is formed of non-magnetic material such as aluminum. The magnetic element 1502 may be incorporated into the coupling feature of the device 108 on the flatbed device 1102. In some embodiments, to prevent metal to metal contact, in those embodiments in which the magnetic element 1502 is metal, a protective film may be attached to a coupling surface of the magnetic element 1502 which prevents the magnetic element 1502 from contacting directly. The protective film may be thin enough to be neglected when considering the force of the coupling. between corresponding magnetic elements. The protective film may be unnecessary if the magnetic element 1502 is not formed of metal or if that portion of the housing 1102 that contacts the magnetic element 1502 is not metal.

The magnetic element 1502 may interact magnetically with the corresponding magnetic element 1504 to the extent of hinge 1340. The magnetic element 1504 may have a thickness of approximately 2 mm. The magnetic interaction can create the net fluid magnetic attractive force by satisfying equation (3a) in which the separation distance Xsep is approximately equal to the total thickness t of housing 1102 and thickness "I" of label 1344. The thickness "I "may be on the order of approximately 0.2 mm. Therefore, in order to minimize the separation distance xsep (and thereby increase Fluid), the magnetic element 1502 may be formed to equalize with the inner surface 1506 of the housing 1102. In addition, the label 1344 and the magnetic element 1504 may be each be formed to suit the outer surface 1508 of the housing 1102. In this way, the distance between the magnetic element 1502 and the magnetic element 1504 can be reduced to approximately the thickness t of housing 1102 and the thickness I of the label. 1344.

In order to further improve the net attractive magnetic force Flux between the magnetic elements 1502 and 1504, the magnetic shunt 1510 may be glued to and surround that portion of the magnetic element 1504 facing away from the housing 1102. The magnetic shunt 1510 may be formed of magnetically active material such as steel or iron. Magnetically active material can redirect magnetic flux lines that would otherwise be directed away from magnetic element 1502 to housing 1102, thereby increasing the density of BTOtal total magnetic flux between magnetic element 1502 and element 1504 resulting in a proportional increase in the net magnetic attractive force. Fluid- Magnetic shunt 1510 can be glued in turn to the T5T2 housing of the T340 hinge extension. It should be noted that in order to ensure that only label 1344 contacts outer surface 1508 of housing 1102 (to avoid metal to metal contact), label 1344 is designed (ie protrudes) from housing 1512 of the hinge extension 1340 for approximately the distance "d". Nominally, the distance d may be on the order of approximately 0.1 mm.

Since the net magnetic force Fl depends in part on the separation distance between the cooperating magnetic elements, the overall integrity of the magnetic union between the magnetic union system on the 1100 tablet device and the magnetic elements on the hinge extension. 1340 may be affected by the actual separation distance between the cooperating magnetic elements as well as the consistency of the separation distance along the length L of the hinge extension 1340. In order to provide a highly correlated magnetic attractive force along of the hinge extension 1340, the separation distances between the magnetic elements in the hinge extension 1340 and those of the magnetic union system in the tablet device 1100 are well controlled.

Figure 21B shows a sectional view 1550 of the extent of the magnetically joined hinge 1340 in housing 1102 having a flat surface. In this arrangement, label 1344 and magnet 1554 may each conform to the flat shape of housing 1102.

In order to ensure the consistency of the net magnetic attractive force along the length L of the hinge extension 1340, the hinge extension components 1340 can be assembled using the artifact 1600 shown in section in figure 22A and in perspective view. perspective in figure 22B. Artifact 1600 may have surface 1602 which conforms to the shape of the outer surface of housing 1102. In order to mount the extension of hinge 1340 in a manner that ensures consistent magnetic attractive force along the length L of the extension of hinge 1340 (as well as providing an aesthetically pleasing appearance), label 1344 may be temporarily bonded to surface 1602 of artifact 1600. Provided that surface IbOii substantially conforms to the shape of outer surface 1508, label 1344 shall have a shape that also conforms to the shape of the outer surface 1508. In one embodiment, a partial vacuum may be created within the artifact 1600 which causes the label 1344 to bond to the surface 1602 under suction. In this way, the extension of the assembled hinge can be separated from the surface 1602 simply by removing the partial vacuum.

After label 1344 is affixed to surface 1602 of artifact 1600, magnetic element 1504 may be placed in direct contact with and bonded to label 1344 using any suitable adhesive. In order to reduce the separation distance as much as possible, the magnetic element 1504 may be shaped to conform to both labels 1344 and surface 1602. In this way, the shaping of both label 1344 and the magnetic element 1504 ensures a minimum separation distance between the magnetic elements 1506 and 1502. The magnetic element 1504 can then be glued to the magnetic shunt 1510 formed of magnetically active materials such as steel to focus the magnetic flux to the magnetic element 1502. Metal shunt 1510 can then be wrapped by and glued to the hinge extension housing 1512 leaving approximately d = 0.1 mm of label 1344 protruding from housing 1512.

In addition to providing protection for the digitizing tablet device 1100, segmented cover assembly 1300 can be manipulated to form useful support structures. Thus, Figures 23 to 26 show useful arrangements of the cover assembly 1300 according to the embodiments described.

For example, as shown in Figure 23, segmented cover assembly 1300 may be folded such that the magnetically active portion of insert 1324 magnetically interacts with magnetic elements 1322. It should be noted that the magnetic force used to maintain the Triangular support structure 1700 is approximately in the range of 5 - 10 newtons (NT). In this way, the triangular support structure 1700 can be prevented from opening inadvertently. Triangular support structure 1700 may be formed to be used in many ways to enlarge the tablet device 1100. For example, triangular support structure 1700 may be used to support the tablet device 1100 in such a way that the Touch surface 1702 is positioned relative to a support surface at an ergonomically advantageous angle. Thus, using the 1702 touch surface can be a pleasant user experience. This is particularly relevant in those situations where the touch surface is used over an extended period of time. For example, a virtual keyboard may be displayed on the touch surface 1702. The virtual keyboard may be used to enter data into the 1100 tablet device. By using the triangular support frame 1700 to support the 1100 tablet device At the ergonomically pleasing angle, the detrimental effects of repetitive motions can be reduced or even eliminated.

Figures 24A and 24B show another folded implementation of segmented cover assembly 1300 in which the three-dimensional support frame 1700 may be used to support the tablet device 1100 in a viewing state. By viewing state it is planned that visual content (visual aids, still life, animation, etc.) can be presented at a pleasant angle to the viewer approximately 75 ° from the horizontal. In this "rest" state, visual content can be displayed for easy viewing. A visible area of the 1100 tablet device can be displayed at an angle of approximately 75 ° that has been found to be within a range of viewing angles considered optimal for a good viewing experience.

Figures 25A-25B show segmented cover assembly 1300 folded into various suspension embodiments. By suspension embodiments, it is envisioned that by folding the segmented cover assembly 1300 into a suitable triangular shape, the flatbed device ΤΤ0Ό may be suspended from above as shown in the form of the suspension 1900. The suspension 1900 may be used to suspend the tablet device 1100 from above. For example, the hanger 1900 may be suspended directly from the ceiling using a support piece such as a rod. The suspender 1900 can be created by simply folding the segmented cover assembly 1300 in a first direction until embedded magnets 1322 magically engage the magnetically active insert 1324 which can be formed of steel or iron. The magnetic circuit formed by engaging the embedded magnets 1322 and magnetically active insert 1324 may provide sufficient support to safely suspend the tablet device 1100 from any horizontally aligned support structure.

Figure 25B shows suspender embodiments suitable for suspending tablet device 1100 from a vertically aligned support structure such as a wall. In particular, the hanger 1910 may be mechanically attached to a wall or other vertical support structure. The suspender 1910 may then be used to suspend the tablet device 1100 along the lines of a wall crimping. In this way, the tablet device 1100 can be used to display visual content along the lines of a visual display for visual content, or wall hanging for still images such as photos, art, and so on.

Figures 26A-26B show the arrangement 2000 where the triangular support structure 1700 may be used as a handle. Again by folding the segmented cover assembly 1300, such that segmented portions interact to form the triangular support structure that can be used as a handle. As such, the flatbed device 1100 can be held as one would hold a viewing book. The body of the segmented cover assembly 1300 may provide convenient securing aspects that may be used to more securely hold the triangular support structure 1700 when being used to hold the tablet device 1100 as a book. In such cases where the 1TUQ digitizer tablet device includes image capture devices such as a 2002 front-facing camera and 2004 rear-facing camera, visual content can be presented by the 1100 tablet device. , the triangular support structure 1700 may be used as a carrier along the lines of a camera grip. As such, the triangular support structure 1700 can provide a convenient and effective mechanism to assist in the image capture process. For example, when used for capturing images, the tablet device 1100 can be securely held by means of the triangular support structure 1700 and the rear-facing camera 2004 can be pointed at an object. The image of the object may then be presented by the tablet device 1100 in the display shown in figure 25B. In this way, both the 2002 front-facing camera and / or the 2204 rear-facing camera can be used to capture still images or video just as in a video conversation or simply watching a video presentation. As part of a video conversation, a video chat participant can easily continue a video conversation while using the 1700 triangular stand to hold the tablet device 1100. Figures 27A - 27C show the 2100 configuration of the set

1300 and flatbed device 1100 illustrating what is referred to as a lurking operating mode of the flatbed device 1100. More particularly, when segment 1304 is lifted from the glass cover 1106, sensors in the device 1100 can detect that segment 1304 and only that segment has been lifted from glass layer 1106. Once detected, the tablet device 1100 can activate only the exposed portion 2102 of the display. For example, the tablet device 1100 may use a Hall Effect sensor to detect that segment 1304 has been lifted from the glass cover 1106. Additional sensors, such as optical sensors, can then detect whether only segment 1304 was raised or if additional segments were raised. "As shown in figure 27B1 when the flatbed device 1100 determines that only segment 1304 is lifted, then the flatbed device 1100 can change the operating state to the" peek "state in which only the exposed portion 2102 of the dial actively displays visual content in the form of icons 2104. Therefore, information in the form of visual content such as time of day, notes, and so on can be displayed for viewing in only that visible portion. After the sensors detect that segment 1304 has been placed back on the glass layer 1106, the digitizer 1100 may return to the previous operating state as a standby state. An icon arranged to respond to a touch is displayed, so that portion of a touch layer corresponding with the visible portion of the dial can also be activated. In addition, as shown in figure 27C, when segments

As additional features are lifted from the cover glass 1106 to further expose the second portion 2106 of the cover glass 1106, the second portion 2106 of the dial may be activated. This way, in "extended" peek mode, additional visual information such as icons 2108 can be displayed on the activated display portions. It should be noted that as the segments are lifted from the cover glass 1106, additional segments of the dial may be activated. In this way, an extended mode of respect can be provided.

Alternatively, the tablet device 1100 can respond to signals from the Hall Effect sensors (s) by simply energizing the display when the tab is moved away from the display and turning off (standby) when the display is covered by the tab. In one embodiment, a subset of magnetic elements 1322 may be used in conjunction with corresponding magnetic elements 402 in coupling facility 110 to secure the cover assembly 1300 on the flatbed scanning device 1100 on the cover glass 1106. In addition, At least magnet 1326 may be used to magnetically activate the sensitive circuit 404. For example, when the segmented cover 1300 is placed over the digitizing tablet device 1100 on the cover glass 1106, the magnetic field of the magnet 1326 can be detected by magnetically sensitive circuit 404 which may take the form of a Hall Effect sensor. Magnetic field detection may cause the Hall Effect sensor 118 to generate a signal that may result in a change in the operating state of the 1100 tablet device.

For example, when Hall Effect sensor 118 detects that segmented cover 1300 is in contact with cover glass 1106 indicating that the display is not visible, then the signal sent by Hall Effect sensor 118 may be interpreted by a on the tablet device 1100 to change the current operating state to the standby state. On the other hand, when segment 1304 is lifted from cover glass 1106, Hall Effect sensor 118 may respond to the removal of magnetic field from magnetic 1326 by sending another signal to the processor. The processor can interpret this signal again by changing the current operating state. The change may include changing the operating state from standby to an active state. In another embodiment, the processor may interpret the signal sent by the Hall Effect sensor 118 in conjunction with other sensors by changing the operating state of the tablet device 1100 to the peek mode in which only that portion of the display exposed by the survey. of segment 1304 is enabled and capable of displaying visual content and / or receiving (or sending) tactile inputs.

In some cases, when segment 1306 is lifted from the glass

1106 at the same time that Hall Effect sensor 118 indicates that segment 1304 is also raised, the presence of sensors in addition to Hall Effect sensor 118 may cause the processor to enter an extended peek mode on the which additional display features corresponding with the additional exposed portion of the display are also enabled. For example, if the tablet device 1100 includes other sensors (such as optical sensors) that can detect the presence of a particular segment, then Hall Effect sensor signals 118 in combination with other sensor signals can provide an indication for It is the processor that a particular portion or portions of the display assembly are currently visible and can thus be enabled to display visual content.

Figure 28A shows cover assembly 2200 according to a particular embodiment. Cover assembly 2200 may include segmented cover 2202 joined to pivot assembly 2204 shown in an exploded view. The pivot assembly 2204 may include end ears 2206 and 2208 pivotally connected to each other by extending the hinge 2210 and connecting rod 2212 (which may be enclosed within the sleeve 2214 which may be attached to or enclosed within). segmented coverage 2202 and not seen). In this way, at least two pivot lines 2216 and 2218 may be provided for pivotally moving end ears 2206 and 2208, hinge extension 2210 and connecting rod 2212. For example, hinge extension 2210 (and end ears 2206 and 2208) may rotate around pivot line 2216, while connecting rod 2212 (and end ears 2206 and 2208) may rotate around pivot line 2218. It should be noted that connecting rod 2212 and hinge extension 2210 can articulate independently of each other. Articulation may occur at the same time or at different times, providing the pivoting assembly 2204 with at least four independent axial directions of rotation.

In order to prevent metal to metal contact when the hinge extension 2210 is magnetically coupled to the graphics tablet 1100, the label 2220 may be affixed to an external surface of the hinge extension 2210 and dampers 2222 may be affixed to a surface. end ears 2206 and 2208. Label 2220 and mortar 2222 may be formed of material that can repeatedly contact housing 102 without ruining or otherwise damaging the appearance of housing 102. Thus, label 2220 and dampers 2222 may be formed of paper, cloth, plastic and adhered to the STTOTfa-C hinge extension 2210 and end pieces 22Ü6 and 2208 using an adhesive such as glue. In some cases, the adhesive may have properties that provide for easy replacement of label 2220 and / or shock absorbers 2222 when required.

Figure 28B shows an assembled embodiment of the pivot assembly.

2204 showing the pivot line 2216 around which the end ears 2206, 2208 and connecting rod 2212 (on sleeve 2214) can rotate in two axial directions (ie, clockwise and counterclockwise). It should be noted that the end ears 2206, 2208 and the hinge extension 2210 can rotate in two axial directions (ie, clockwise and counterclockwise) with respect to the pivot line 2218. In this way, the end ears 2206 and 2208 can rotate around pivot line 2216 and pivot line 2218 with a total of four axial directions.

Figure 28C shows the extension of the hinge 2210 illustrating in more detail the end pins 2224 and 2226 that can be used to mount the extension of the hinge 2210 to the end ear 2206 and end ear 2208, respectively. Although not visible in this figure, end pins 2224 and 2226 can still be used in conjunction with internal plugs to secure the end unit magnetic elements incorporated within the hinge extension 2210. This is particularly useful in such situations where the magnetic sequence The coding of the magnetic elements incorporated within the extension of the hinge 2210 causes the end unit magnetic elements to magnetically repel the adjacent neighboring magnetic element. Figure 28D shows an exploded view of the extension of the fold.

2210 according to the methods described. Magnetic elements 2228 may be configured as a coded magnetic structure in which individual magnetic elements may be arranged to a specific pattern of magnetic polarity, intensity, size, and so forth. In the embodiment shown, these close magnets having anti-aligned polarity can rely on their mutual magnetic attraction to maintain their position with the encoded magnetic structure. However, magnetic elements placed close together having aligned magnetic polarity may require an external force to overcome the mutual magnetic repulsive force in order to maintain their position within the encoded magnetic structure. For example, magnetic elements 2228-1 and 2228-2 may each be formed of two magnets having aligned magnetic poles. In this situation, each of the two magnets that make up the magnetic element 2228-1 (and 2228-2), for example, will have magnetic poles that align and thus generate a net magnetic repulsive force between them. Therefore, an externally applied restriction can be applied using, for example, buffers 2232-1 and 2232-2 respectively. The magnetic attractive force provided by magnets 2228-3 and 2228-4 (which are anti-aligned with respect to magnets 2228-1 and 2228-2, respectively) can help stabilize the encoded magnetic structure enclosed within the extension of the hinge. 2210. The spacer 2234 formed of magnetically inert material may be used to provide additional physical integrity to the encoded magnetic structure formed by the magnetic elements 2228.

In order to improve the overall net magnetic attractive force, the magnetic derivation 2236 formed of the magnetically active material such as steel may be adhesively bonded to one rear end of the magnetic elements 2228. The placement of the rear end of the derivation 2236 can help redirect magnetic field lines that would otherwise propagate away from the engaging surface between the hinge extension 2210 and housing 1102. By diverting the magnetic field lines back to the engaging surface, the The magnetic flux density provided by the magnetic elements 2228 on the coupling surface may be increased proportionally resulting in an increased net magnetic attractive force between the magnetic elements 2228 and the corresponding magnetic components within the housing 1102.

As previously discussed, label 2220 may be adhesively bonded to magnetic elements 2228 (and spacer 2234, if present) which in turn may be adhesively bonded to magnetic shunt 2236. Magnetic shunt 2236 may be adhesively bonded to the opening 2238 in the extension of the hinge 2210 leaving the label 2220 projected for approximately a distance "d" which may be in the order of approximately 0.1 - 0.2 mm preventing metal to metal contact between the extension of the hinge 2210 and the housing 1102.

Note that in keyboard layout and keyboard layout

For example, the hinge extension 2210 may experience a shear force due to placing the tablet device 1100 on a support surface at an angle. The shear force may be counteracted by the net magnetic attractive force generated between the extension of the hinge 2210 and the bonding feature of the tablet device 1100.

Figure 29 shows an exploded view of the segmented cover 2202. The bottom layer 2250 may come into direct contact with a protected surface, such as a cover glass for a dial. The bottom layer 2250 may be formed of a material that can passively clean the protected surface. The material may be, for example, a microfiber material. The bottom layer 2250 may be joined to the reinforcing layer 2252 formed of resilient material, such as plastic. Reinforcement layer 2252 may in turn be adhesively bonded to inserts 2254 to form a laminate structure including adhesive layer 2256, laminate 2258 and insert 2254. Some of the inserts 2254 may accommodate inline components. For example, insert 2254-1 may accommodate magnets 2260, some of which may cooperate with the corresponding bonding feature 110 embedded in the tablet device 1100 to secure the segmented cover 2202 in the tablet device 1100. At least one 2260-1 magnet may be positioned and sized to interact with a magnetically sensitive circuit (such as a Hall Effect sensor) embedded within the 1100 tablet device. It should be noted that although some of the 2260 magnets specifically allocated to interact only with bonding feature 110, substantially all magnets 2260 can magnetically interact with the magnetically active plate 2262 embedded in segment 2254-2 used to form various triangular support structuresT1 Thus, a strong magnetic force can be generated by providing a stable foundation for the triangular support structure.

An additional laminate structure may be formed of adhesive layer (s) 2256, laminate material 2258 and upper layer 2264. In some embodiments, an intermediate layer of material may be provided having an interlaced structure which may be assist in bonding the topsheet 2264. The topsheet 2264 can be formed of many materials such as plastic, leather and so on while preserving the overall look and feel of the 1100 tablet device. In order to provide additional structural support , the topsheet 2264 may have edges reinforced by reinforcing bars 2266 which may be formed of plastic or other rigid or semi-rigid material.

Figure 30 shows a partial sectional view of the segmented cover 2200 shown in figure 29 placed in position on the cover layer 1106 of the flatbed device 1100. Of particular note is the relative positioning of magnet 2260-1 and Hall Effect sensor 118. Thus, when segmented sheath 2200 is placed over sheath layer 1106, the magnetic field of magnet 2260-1 can interact with the Hali 118 sensor that can respond by generating a signal. The signal may be processed in turn in such a way that the operating state of the tablet device 1100 may change according to the presence of the cover 2200. On the other hand, the removal of the cover 2200 may cause the operating state reverts to the previous operating state or other operating state such as lookup mode. It should be noted that the magnetic field density between the magnetic element 2260-1 and the Hall Effect sensor 118 can be in the order of approximately 500 Gauss. However, in such embodiments where the cover 2202 is moved to the rear of the housing 1102, the magnetic flux density in the Hall Effect sensor 118 may be in the order of approximately 5 Gauss.

Fig. 31A shows the cross-sectional view of the active hinge extension 22 extensão0 with device 2300 bonding feature incorporated in the tablet device 1100. In particular, magnetic bonding feature 2300 includes at least magnetic element 2302. forming a magnetic circuit with magnetic element 2228 (which is part of the encoded magnetic structure incorporated in the hinge extension 2210). Magnetic shunt 2304 can be used to redirect magnetic field lines that propagate from magnetic element 2302 in a different direction from magnetic element 2228. In this way, the magnetic flux density on the coupling surface 2306 can be proportionally increased, thereby increasing the net magnetic attractive force. The magnetic coupling feature 2300 can be incorporated into cylinder 2308 in housing 1102 sized to accommodate both magnetic element 2302 and lead 2304. In the embodiment described, the cylinder 2308 may provide support for magnetic element 2302 and shunt 2304. cylinder 2308 may also direct movement of magnetic element 2302 and shunt 2304 when magnetic bonding feature 2300 transits between active and inactive states.

In order to ensure that the fluid net attractive force is applied substantially normal to the engagement surface 2306, the magnetization of the magnetic element 2228 and magnet element 2302 can be configured such that their respective magnetization vectors Μ align substantially. Highly. By magnetization it is intended that magnets can be manufactured having magnetic domains that are substantially aligned in the same direction. By aligning the magnetization vectors M1 and M2 of the magnetic element 2302 and the magnetic element 2228, respectively, the liquid magnetic force may be generated substantially normal to the coupling surface 2306.

Figure 31B shows the magnetic bonding feature 2300 in an inactive state. When in idle state, the magnetic bonding feature 2300 is located at least a distance X0 from the outer surface of housing 1102 to satisfy equation (1). Therefore, cylinder 2308 must be capable of accommodating the movement of magnetic element 2302 and derivation 2304 from x = 0 ~ n idle incremented to approximately x = X0 in the active state.

Fig. 32 shows a representation of one embodiment of the coupling feature of device 108 in the form of coupling feature 2400. In particular, coupling 2400 may include magnetic elements 2402 / shunt 2404 joined to leaf spring 2406. Leaf spring 2406 can be attached directly to junction 2404 by means of fasteners 2408 and end supports 2410 by means of fasteners 2412. End supports 2410 may be joined into a support structure such as a housing to provide support for the coupling feature 2400. In one embodiment, alignment columns 2414 may be used during mounting to provide alignment for both end brackets 2410 and leaf spring 2406. Figure 33 shows a close view of the frame interface support 2410 / leaf spring 2406. Figure 34 shows a flow chart detailing a 2500 process

according to the described modalities. The process can begin at 2502 by providing a first magnetic union feature encoded in an inactive state. At 2504, using a second magnetic union feature to activate the first coded magnetic union feature. At 2506, causing the interaction of a magnetic field of the first activated magnetic union feature with a magnetic field of the second magnetic union feature. In 2508, generating a net magnetic union force according to the interaction of the magnetic fields. In 2510, magnetically connecting the first and second magnetic bonding features according to the net magnetic bonding force.

Fig. 35 shows a flow chart detailing process 2600 according to the embodiments described. Process 2600 may begin at 2602 by providing an encoded magnetic union feature in an inactive state. In the idle state, the magnetic flux density at a predetermined distance for magnetic elements in the encoded magnetic union feature is less than a threshold value. At 2604, an external magnetic field is received in the encoded magnetic union feature. In 2606, if it is determined that the external mayretic canipu - corresponds with the magnetic elements that correlate with the magnetic elements in the encoded magnetic union feature, then in 2608, the encoded magnetic union feature is activated. otherwise, process 2600 ends.

Figure 36 shows a flowchart detailing process 2700.

according to the described modalities. Process 2700 may begin at 2702 by placing an electronic device having a first and an accessory having second coded magnetic union features in close proximity to one another. At 2704, if the magnetic elements in the first and second coded magnetic union features correlate, then at 2706, the first coded magnetic union feature is activated. When the first coded magnetic union feature is activated, then the magnetic flux density of a magnetic field generated by the first coded magnetic union feature increases to a value above a threshold. The interaction of the magnetic field between the magnetic elements in the first and second magnetic union features causes the electronic device and the accessory to magnetically unite in 2708.

Figure 37 shows a flowchart detailing a lurking process 2800 according to the embodiments described. Process 2800 can start at 2802 by determining if a first portion of a dial is uncovered. By discovery it is intended that the visual content presented in the first portion can be viewed. When it is determined that the first portion of the dial is uncovered, then in 2804, only that portion of the dial that has been found to be uncovered can display visual content. In other words, a set of icons or other visual content may be displayed on the uncovered portion of the display, where the rest of the display may remain blank or off. Next at 2806, visual content is displayed by the activated portion of the display. Next in 2808, a determination is made whether a second portion of the dial is uncovered, the second portion being different from the first portion. When it is determined that the second portion of the display is uncovered, then a second portion of the display is activated at 2810. Visual content is then displayed at the second portion at 2812.

Fig. 38 shows a flowchart detailing the process 2900 for forming a magnetic stack incorporated into the hinge extension 1340 according to the described embodiments. The 2900 process for forming the magnetic stack incorporated in the hinge extension 1340 may begin in 2902 by providing an artifact. The artifact having a shape in accordance with the outer shape of the housing which defines the electronic device over which the hinge extension will magnetically join. The artifact may also be connected to a vacuum source which may subsequently be used to secure a protective film by 2904. The protective film may be used to provide protection against metal-to-metal contact between the hinge extension and the housing of the electronic device. The protective film (also cited as a label) may be formed of resilient material and have a length consistent with that of the hinge extension. After the label has been affixed to the artifact using a vacuum, the label takes the shape of the artifact outline and thus the housing shape of the electronic device.

In 2906, a magnet is attached to the label on a first surface formed to conform to the artifact (and housing). In one embodiment, the label and magnet may be glued together using adhesive. In another embodiment, the label may have a glue-impregnated adhesive inner layer that may bond the label on the magnet with the cure. In 2908, a magnetic lead is glued to the magnet and label assembly. The magnetic shunt may be formed of magnetically active material such as steel. The magnetic shunt may interact with these lines of the magnet's magnetic field initially directed away from the engaging surface between the housing and the hinge extension. The magnetic shunt may interact with the magnetic field lines by redirecting at least some of the magnetic field lines in one direction to the magnet and the coupling surface. The redirected magnetic field lines can increase the density of the magnetic flux at the coupling surface, thus forming a magnetic force trapped between the magnetic elements in the electronic device and the extension. of the hinge.

At 2910, a hinge extension housing can be glued to the magnetic shunt. The hinge extension housing can be used to support and protect the magnetic elements used to magnetically attach the hinge extension to the electronic device. It should be noted that upon joining the hinge extension housing, the label is projected from the hinge extension housing so that the label is designed to project a distance "d" from the hinge extension housing. Thus, there is no contact between the metal hinge extension housing and the metal housing of the electronic device.

Fig. 39 shows a flowchart detailing the process 3000 for determining a configuration of the magnetic elements in a magnetic stack used in a magnetic bonding system according to the described embodiments. Process 3000 begins at 3002 by providing a first plurality of magnetic elements according to a first configuration. At 3004, a second plurality of magnetic elements according to a second configuration is provided. By first and second configurations, what is planned is that the first and second pluralities of magnetic elements may be arranged in any manner deemed appropriate. For example, the first and second configurations may relate to a physical size, a magnetic polarity, a magnetic intensity, a relative position relative to other magnetic elements, and so on. Next, at 3006, a net magnetic force is created in one embodiment by positioning each of the first and second pluralities of magnetic elements with respect to each other. In doing so, these corresponding magnetic elements having the same polarity will generate a negative (repulsive) magnetic force while these corresponding magnetic elements having opposite polarities will generate a positive (attractive) magnetic force. At 3008, the total net magnetic force value for each corresponding first and second plurality of magnetic elements is determined. As mentioned above, since some magnetic elements can generate a negative magnetic force while others a positive magnetic force for the same position, the total value of the net magnetic force can be positive, negative or zero (indicating that positive and negative magnetic fields cancel out not producing the overall net magnetic force).

By 3010, the difference between a global maximum net total magnetic force and the first local maximum net total magnetic force is determined. For example, as shown in Figure 13, the global maximum corresponds to a total net magnetic force of approximately 8A ("A" being a unitary magnetic attractive force where "8A" is equivalent to "+8" where "+" indicates attractive force). In addition, a first local maximum net total value is approximately 4A and a second local maximum net total value is approximately 1A. In order to avoid "false activation" that may result in weak magnetic attraction, the difference between the global maximum net total magnetic force and the first local maximum net total magnetic force may indicate a probability that the bonding system magnetic will balance on the global maximum net total magnetic force (representing the strongest net magnetic attraction) and the first local maximum net total magnetic force (representing a weak net magnetic attraction).

Therefore, if at 3012 the difference is acceptable (meaning that the global maximum is the probable equilibrium point), then process 3000 stops, otherwise the configuration of the magnetic elements is changed at 3014 and control is passed. directly to 3006 for further evaluation.
