BACKGROUND

Impact injuries are sustained from impacts of objects against an individual and impact of the individual against objects. Impact injuries include blunt force traumas, punctures, concussion, broken bones, damaged joints, and other medical conditions. Equipment for prevention of impact injuries has existed for many centuries in many forms, including medieval armor and ancient Egyptian helmets.
Prevention of impact injuries has led to the development of modern safety equipment, such as hardhats, batting helmets, football pads, knee-braces, and body armor such as bullet proof vests, etc. Some safety equipment useful for preventing impact injuries is bulky, cumbersome, heavy, and can limit movement. For example, football pads can limit movement and tend to be bulky. Knee or other joint braces can unduly limit range of motion. Body armor tends to be bulky, heavy, and may limit range of motion in some cases.

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
FIG. 1 is a schematic of a system 100 for protecting an individual 102 from injuries such as impacts, punctures wounds, concussion, etc., according to an embodiment. The system 100 includes one or more protective members 104, one or more sensors 106, and at least one controller 108. At least one of the one or more protective members 104, one or more sensors 106, or at least one controller 108 can be supported by a supportive member 110. The supportive member 110 can be worn by the individual 102. The one or more protective members 104 are configured to change from a first state to a second state responsive to direction from the at least one controller 108. In the first state, the protective members 104 can be configured to provide relative flexibility or freedom of movement to one or more of a body part of the individual (e.g., leg, abdomen, etc.) or at least a portion of the supportive member 110 adjacent thereto. In the second state, the protective members 104 can be configured to provide relative inflexibility or rigidity to one or more of the body part of the individual 102 or at least a portion of the supportive member 110 adjacent thereto for enhanced protection of the individual 102 from injuries. In an embodiment, the first state may provide less relative flexibility than the second state. The relative inflexibility state may provide one or more of impact resistance, structural support, or force-dampening effects to a body part of the individual 102 or to the supportive member 110.
The one or more sensors 106 are configured to sense at least one of a potential impact or an actual impact, as described in detail below. The sensed potential impact or actual impact can be relayed from the one or more sensors 106 to the controller 108 as described in detail below. The controller 108 is configured to selectively direct one or more of the protective members to alter from the first state to the second state, vice versa, or some state therebetween, responsive to the sensed impact or potential impact as described in detail below.
In an embodiment, at least a portion of the protective member 104 or the supportive member 110 is configured to conform or be conformable to one or more body regions of the individual 102. For example, the body region of the individual 102 can include an abdominal region, a spinal region, a back region, a thoracic region, an arm, or another portion of the individual 102.
FIG. 2 is a schematic view of a portion of a protective member 204 incorporated in a system 200 for protecting an individual from injuries, according to an embodiment. The protective member 204 can be supported by, for example, being at least partially disposed in, attached to, or incorporated with a supportive member (e.g., supportive member 110 of FIG. 1). The protective member 204 can be supported by the supportive member to at least partially protect the individual wearing the supportive member from injuries that can occur during a hazardous event.
In an embodiment, the supportive member includes an article of clothing, apparel, or gear that supports one or more components of a system (e.g., the system 100 of FIG. 1). For example, the supportive member can be athletic apparel or gear (e.g., football jersey, a rib guard, a hockey girdle, shoulder pads, etc.), and the protective member 204 can be supported by the supportive member to at least partially protect the individual from injuries that can occur during an athletic event. In another example, the supportive member can be apparel or gear that is worn during a potentially hazardous activity. The hazardous activity can be an activity that includes projectiles or other actual or potential impact sources. In particular, the supportive member can be at least a portion of military apparel, policeman's uniform, fireman's uniform, first responder's uniform, construction worker's apparel, paintball apparel, ski apparel, motorcycle safety apparel, tactical gear, or other similar items. In such an example, the protective member 204 can be positioned on the supportive member to protect a portion of the individual that is not protected by the other safety equipment or can be positioned to protect a portion of the individual that is already protected by the other safety equipment. In an embodiment, the supportive member includes supportive gear or appeal. For example, the supportive gear or apparel can include a wrap, a brace, or an athletic supporter. In an embodiment, the supportive member includes a bandage or wound dressing. In an embodiment, the supportive member can include fabric, such as one or more a natural fabric (e.g., cotton, leather, wool, etc.), synthetic fabrics (e.g., nylon, polyester such as neoprene, etc.), or one or more polymers (e.g., a plastic helmet).
The protective member 204 is formed from two or more layers. For example, the protective member 204 includes at least one passive layer 212 and at least one active layer 214 coupled to the passive layer 212. The active layer 214 includes at least one energy-responsive material that changes at least one physical property thereof responsive to at least one stimulus energy 215 being delivered thereto. The protective member 204 further includes at least one energy source 216 that is operably coupled to the active layer 214 and is configured to output and deliver the stimulus energy 215 (e.g., controllably deliver a selected magnitude of the stimulus energy) to the energy-responsive material. In an embodiment, the protective member 204 or the supportive member supporting the protective member 204 can include one or more sensors 206. The sensors 206 can be configured to sense at least one of a potential impact or an actual impact against the individual wearing the supportive member. The protective member 204 can also include at least one controller 208 including control electrical circuitry. The controller 208 can be communicably coupled to one or more components of the protective member 204. The control electrical circuitry can be configured to at least partially control at least some of the components to which the controller 208 is communicably coupled.
The passive layer 212 can include any suitable material. For example, the passive layer 212 can include one or more suitable materials that do not substantially change at least one physical property thereof when the active layer 214 is subjected to the stimulus energy 215 or responsive to receiving or interacting with the stimulus energy 215. In an embodiment, the passive layer 212 can include at least one fabric. For example, the fabric can include one or more of wool, cotton, silk, linen, nylon, spandex, rayon, polyester, acrylic, another natural fabric, or another synthetic fabric. In an embodiment, the passive layer 212 can be configured to provide some form of protection to an individual. For example, the passive layer 212 can include one or more of a foam, Kevlar, Lexan, a carbon fiber composite material, a tear-resistant material, an indentation-resistant material, an impact-resistant material, or a force-dampening material. In an embodiment, the passive layer 212 can be configured to apply the stimulus energy 215 to the active layer 214 (e.g., the passive layer 212 can include the energy source 216). In an embodiment, the passive layer 212 can include one or more water-resistant or waterproof materials (e.g., water-repelling coating, polyethylene, a water-resistant membrane). In an embodiment, the passive layer 212 can substantially be the same as the supportive member 110.
In an embodiment, the passive layer 212 or the active layer 214 can be configured to directly contact at least one body region of an individual. In an embodiment, the passive layer 212 or the active layer 214 can form an exterior or interior layer of the protective member 204. For example, the passive layer 212 can form both an exterior and interior layer such that the passive layer 212 at least partially or completely surrounds the active layer 214, or vice versa. In an embodiment, the passive layer 212 or the active layer 214 can form all or part of athletic apparel or gear. For example, the passive layer 212 or the active layer 214 can define a plurality of perforations, absorb sweat, include one or more logos, numbers, or letters, etc. In an embodiment, the passive layer 212 or the active layer 214 can include a material that stretches or is flexible such that the protective member 204 better conforms or is conformable to at least one body region (e.g., at least one surface of the body region) of the individual and does not inhibit movement of the individual. In an embodiment, the passive layer 212 or the active layer 214 can naturally conform to at least one body region of a specific individual (e.g., specifically designed or manufactured to be worn by the specific individual). For example, the at least one body region of the specific individual can be scanned to sense a topography using any suitable method (e.g., 3D laser scanning), and the passive layer 212 or the active layer 214 is formed (e.g., by 3-dimensional printing) to substantially conform to the at least one body region of the specific individual. In another example, the passive layer 212 or the active layer 214 can be applied to the at least one body region of the specific individual and the passive layer 212 or the active layer 214 can be treated (e.g., heat treated) to substantially conform to the at least one body region of the specific individual. In an embodiment, the passive layer 212 or the active layer 214 can form at least a portion of or be distinct from the supportive member. In an embodiment, the protective member 204 and supportive member are substantially a single unit.
The passive layer 212 and the active layer 214 can be coupled together using any suitable method. For example, the protective member 204 can include at least one of an adhesive, stitches, one or more mechanical fasteners such as rivets, screws, or clamps, or another suitable attachment mechanism that couples the passive layer 212 and the active layer 214 together.
The active layer 214 can include any suitable energy-responsive material that changes at least one physical property thereof responsive to receiving the stimulus energy 215. In an embodiment, the energy-responsive material can be or include at least one of a solid or a fluid (e.g., liquid, gas, or gel). In an embodiment, the energy-responsive material can include at least one of an electrorheological fluid, a magnetorheological fluid, an electroactive polymer, a non-Newtonian fluid, or an auxetic material. In an embodiment, the energy-responsive material can include a piezoelectric material, a ferrofluid, or another suitable material. In an embodiment, the energy-responsive material can include any suitable material that changes (e.g., increases or decreases) at least one of a stiffness thereof, a volume thereof, a cross-sectional area thereof in at least one direction, a density thereof, a viscosity thereof, a shear modulus thereof, an elastic modulus thereof, a yield stress thereof, a density thereof, etc. responsive to the stimulus energy 215. In an embodiment, the active layer 214 can include a material that exhibits a phase change or shape change (e.g., elastic or inelastic deformation) responsive to the stimulus energy 215.
In an embodiment, the active layer 214 can at least substantially only include the energy-responsive material. In an embodiment, the active layer 214 can include the energy-responsive material and at least one passive material (e.g., a material that does not change a physical property thereof responsive to the stimulus energy 215). For example, the energy-responsive material can include a liquid and the active layer 214 can include a reservoir at least partially formed from the passive material. In an embodiment, the active layer 214 can include a composite that includes the energy-responsive material and the passive material. In an embodiment, the passive material can form part of the energy source 216 that is at least partially positioned in or on the active layer 214.
In an embodiment, the energy-responsive material can include a plurality of different energy-responsive materials. For example, the energy-responsive material can include a first energy-responsive material and a second energy-responsive material that is different than the first energy-responsive material. In an embodiment, the first energy-responsive material can change at least one physical property thereof responsive to being subjected to a first stimulus energy, and the second energy-responsive material can change at least one physical property thereof responsive to being subject to a second stimulus energy that is different than the at least one first stimulus energy. In an embodiment, the first and second energy-responsive materials can change at least one physical property thereof responsive to the same stimulus energy.
In an embodiment, the active layer 214 can be configured to be switchable between at least a first and second state. The active layer 214 can be in the first state when the stimulus energy 215 is not actively delivered to the energy-responsive material. The energy-responsive material can exhibit a first physical property when the active layer 214 is in the first state. The active layer 214 can be in the second state when a first stimulus energy is actively delivered to the energy-responsive material. The at least one energy-responsive material can exhibit a second physical property that is different from the first physical property when the active layer 214 is in the second state. In an embodiment, the active layer 214 can be configured to be switchable between the first state, the second state, and at least one additional active state (e.g., a third state) that is different than the first and second states. The active layer 214 can be in the third state when a second stimulus energy is actively delivered to the energy-responsive material. The second stimulus energy can be different from the first stimulus energy. For example, the second stimulus energy can be a different type of stimulus energy than the first stimulus energy (e.g., the first stimulus energy can be a magnetic field and the second stimulus energy can be an electric field), the at least one second stimulus energy can exhibit a different magnitude that the at least one first stimulus, etc. The at least one energy-responsive material can exhibit a third physical property when the active layer 214 is in the third state.
The energy source 216 can include any device configured to subject the active layer 214 to the stimulus energy 215. In an embodiment, the energy source 216 can be configured to output at least one of electrical energy, magnetic energy, mechanical energy, thermal energy, electromagnetic energy, or another suitable type of energy. For example, electrical energy can be an electric field generated from one or more electrodes or one or more electrode pairs. For example, the magnetic energy can be a magnetic field generated from one or more electromagnets or one or more permanent magnets. For example, the mechanical energy can be generated from one or more piezoelectric actuators, one or more shape memory alloy actuators, one or more hydraulic actuators, one or more microelectromechanical systems (MEMS), one or more nanoelectromechanical systems (NEMS), etc.
In an embodiment, the energy source 216 can be directly coupled to the active layer 214. For example, the energy source 216 can be at least partially positioned in or on the active layer 214. In an embodiment, the energy source 216 can be remote from the active layer 214. For example, the energy source 216 can be at least partially positioned in or on the passive layer 212. In an embodiment, the energy source 216 can be spaced from the protective member 204 (e.g., attached to or otherwise supported by a portion of the supportive member).
In an embodiment, the energy source 216 can include a plurality of energy sources. For example, the energy source 216 can include a first energy source and a second energy source that is different from the first energy source. The first energy source can be configured to deliver a first stimulus and the second energy source can be configured to deliver a second stimulus source to the energy-responsive material. For example, the energy-responsive material includes a first and second energy-responsive material that changes at least one physical property thereof responsive to the first and second stimulus energy, respectively. In an embodiment, the energy-responsive material exhibits a first, second, and third physical property that are each different. The energy-responsive material can exhibit the first physical property when no stimulus energy is delivered thereto, the second physical property when the one first stimulus energy is delivered thereto, and a third physical property when the second stimulus energy is delivered thereto. In an embodiment, the at least one energy source 216 can include a single energy source.

In an embodiment, at least one of the sensors 206 is at least partially positioned in or on the protective member 204. In an embodiment, at least one of the sensors 206 is spaced from the protective member 204 and at least partially positioned in or on the supportive member. In an embodiment, at least one of the sensors 206 is spaced from the protective member 204 and the supportive member. For example, at least one of the sensors 206 can be at least partially positioned in a playing field, a stadium, a device that monitors the supportive member (e.g., the central computing unit 1054 of FIG. 10), another structure, or other remote location.
In an embodiment, the sensors 206 can be configured to sense one or more characteristics of at least one of a potential impact source or actual impact source. For example, the sensors 206 can sense a radius of curvature, a color, a roughness, size, a hardness, a density, etc. of the potential impact source or actual impact source. The potential impact source or actual impact source can be another individual, another athlete (e.g., a football player), a projectile (e.g., a ball, falling debris), a surface (e.g., a road, a playing surface, a fence), etc. In an example, an optical sensor can sense a radius of curvature to determine if the impact source includes a sharp edge. In an example, an acoustic sensor can sense a hardness of an impact source.
In an embodiment, the sensors 206 can be configured to sense the actual impact against the protective member 204, the supportive member, or the individual.

The movement of at least a portion of the individual, of the supportive member, of the potential impact source, or of the actual impact source includes at least one of a position, direction of movement, speed, acceleration, deceleration, or direction of acceleration or deceleration of the individual, the supportive member, the potential impact source, or the actual impact source. In an embodiment, the sensors 206 can be configured to sense one or more characteristics of the protective member 204, the supportive member, or the individual. For example, the sensors 206 can be configured to sense the spatial location, heartrate, perspiration, oxygen level, etc. of the individual that can be indicative of a potential impact or an actual impact against the individual. In an embodiment, the sensors 206 are configured to sense a time of day, an activity, a location, etc.

In an embodiment, at least one of the sensors 206 can be configured to sense one or more characteristics of a specific portion of the protective member 204 (e.g., segments 844 a-d of FIGS. 8A-8D), the supportive member, the individual, or a location external therefrom. For example, one of the sensors 206 can be configured to sense a force of an actual impact against a specific portion of the supportive member (e.g., protective member 204). In such an example, the sensors can include a first sensor configured to sense a force against a first selected portion of the supportive member and a second sensor configured to sense a force against a second selected portion of the supportive member distinct from the first selected portion. In an embodiment, at least one of the sensors 206 can be configured to sense one or more characteristics of the entire protective member 204, the entire supportive member, the entire individual, or a relative large location external therefrom.
In an embodiment, the sensors 206 can be communicably coupled to one or more components of the protective member, the supportive member, or a device distinct from the protective member and the supportive member (e.g., the central computing unit 1054 of FIG. 10B). As such, the sensors 206 can transmit the sensed information signals 217 responsive to sensing the characteristics. For example, the sensed information signals 217 can include data encoded therein including the sensed characteristics. In an embodiment, the sensors 206 can sense the characteristics or transmit the sensed information signals 217 responsive to direction from the controller 208.
In an embodiment, the sensors 206 can include a plurality of sensors. For example, the plurality of sensors can include at least a first sensor and a second sensor. In an embodiment, the first and second sensors can be configured to sense the same characteristic. In an embodiment, the first sensor can sense a first characteristic and the second sensor can be configured to sense a second characteristic that is different than the first characteristic. In an embodiment, the first sensor can be coupled to a first location, and the second sensor can be coupled to a second location that is different than the first location. In an embodiment, at least some of the plurality of sensors 206 can be attached together or positioned adjacent to each other to form a sensor array.
The controller 208 can include control electrical circuitry configured to at least partially control the operation of one or more components of the system 200. For example, the controller 208 can include at least one memory storage medium 218 and at least one processor 219 including processing electrical circuitry operably coupled to the at least one memory storage medium 218. The controller can include an interface 221 (e.g., a transceiver). The controller 208 can be configured to determine if the energy source 216 should deliver the stimulus energy 215 to the active layer 214, based at least partially on the one or more sensors 206 sensing at least one of a potential impact or an actual impact of the individual. The controller 208 can be operably coupled (e.g., wirelessly or wiredly communicably coupled) to the energy source 216 and at least some of the sensors 206. The at least one controller 208 can at least partially control the energy source 216 to emit the stimulus energy 215 to the active layer. The controller 208 can at least partially direct the energy source 216 responsive to the sensed potential or actual impact. For example, the controller 208 can direct the energy source 216 to controllably deliver the stimulus energy 215 (e.g., deliver a selected magnitude or intensity of the stimulus energy 215) to the active layer 214 responsive to the potential or actual impact. For instance, the controller 208 can direct the energy source 216 to controllably deliver a relatively low magnitude of the stimulus energy 215 to the active layer 214 responsive to a relatively weak potential or actual impact such that the active layer is not fully activated. In an embodiment, the controller 208 can be configured to direct the energy source 216 to deliver the stimulus energy 215 to a region of the active layer 214 that is at or adjacent to a sensed actual impact or potential impact location. In an embodiment, the controller 208 can direct the energy source 216 to deliver the stimulus energy 215 to the energy-responsive material at one or more selected magnitudes. In an embodiment, the controller 208 can direct the sensors 206 to sense one or more characteristics.
In an embodiment, the controller 208 can be at least partially positioned in or on the protective member 204. In an embodiment, the controller 208 can be distinct from the protective member 204 and at least partially positioned in or on the supportive member. In an embodiment, the controller 208 can be spaced from the protective member 204 and the supportive member.
In an embodiment, the at least one controller 208 can include a plurality of controllers, each operably coupled to at least one of the sensors 206. For example, each of the plurality of controllers can be operably coupled to at least one of the sensors 206, (e.g., sensors of a distinct region). In another example, each of the plurality of controllers can be configured to determine if a distinct region of the protective member 204 is experiencing at least one of an actual impact or potential impact. For instance, each of the plurality of controllers can be associated with the distinct region of the protective member 204. Each of the plurality of controllers can be configured to direct the energy source 216 to deliver the stimulus energy 215 to the distinct region of the protective member 204. For example, the energy source 216 can include a plurality of energy sources, and each of the plurality of energy sources can be configured to deliver a stimulus energy 215 to a distinct region of the protective member 204. In an embodiment, each of the plurality of controllers can be configured to communicate with other controllers of the plurality of controllers.
In an embodiment, the plurality of controllers can include at least one primary controller and at least one secondary controller. The primary controller can be configured to control the operation of the secondary controller. For example, the supportive member 210 can include a plurality of segments (e.g., segments 844 a, 844 b, 844 c, or 844 d of FIGS. 8A-8D). The at least one secondary controller can include a plurality of secondary controllers and at least some of the plurality of segments can include at least one of the plurality of secondary controllers disposed therein or thereon. The primary controller can relay instructions to one or more of the secondary controllers and the secondary controllers can at least partially control the operation of the segments responsive to receiving the instructions from the primary controller. In another example, the primary controller can be remote from the supportive member (e.g., CCU 1054 of FIG. 10B).
The memory storage medium 218 can be physically disposed in the controller 208 or separate from and communicably coupled to the controller 208. The at least one memory storage medium 218 can include any non-transitory memory storage medium, such as a hard-disk drive, a solid state memory device, a flash drive, or the like. The at least one memory storage medium 218 can include one or more of program instructions for the at least one processor 219, data from the one or more sensors 206 (e.g., present or previous sensed motion characteristics such as potential impacts, actual impacts, or forces associated therewith), threshold values for one or more forces or characteristics sensed by the one or more sensors 206, a history of the protective member 204 (e.g., deployment or stimulation history of each protective member 204, current status of the protective garment system, etc.), a history of potential or actual impacts against the protective member (e.g., potential or actual impacts against the protective member 204, potential or actual impacts against a region of the protective member 204, or potential or actual impacts against one or more segments of the protective member 204), look-up tables corresponding to any of the proceeding, one or more databases, or system diagnostic statuses (e.g., current and past statuses, or readiness states of any components of the system).
The at least one processor 219 can be operably coupled to the at least one memory storage medium 218 via the connection 222. The at least one connection 222 can be a wireless connection or a hardwired connection. The at least one processor 219 is configured to access and read the memory storage medium 218. The at least one processor 219 is configured to receive sensor data indicating a potential or actual impact. The at least one processor is configured to direct the energy source 216 to deliver the stimulus energy 215 to the active layer 214.
The at least one processor 219 is configured to determine if the energy source 216 should deliver the stimulus energy 215 to the active layer 214, at least partially based on one or more characteristics sensed by the one or more sensors 206. For example, the one or more sensors 206 can sense one or more objects within a specific proximity of the system 200, protective member 204, or the individual, and the processor 219 can determine if the proximity is below a threshold value for safety. The threshold value can include an impact threshold level (e.g., a selected likelihood that a potential impact will impact the supportive member, the potential or actual impact will impact the supportive member at or above a selected force or pressure) or an injury threshold level (e.g., a selected likelihood that the potential or actual impact will cause injury, a selected likelihood that the potential or actual impact will cause a selected injury, etc.). In an embodiment, the one or more sensors 206 can sense a velocity of the one or more objects (e.g., the ground or a person) relative to the individual, the protective member 204, or one or more sensors 206, and determine if the velocity is indicative of a potential impact therewith. In an embodiment, the one or more sensors 206 can be configured to sense a force or pressure applied thereto, and, responsive to the sensed force, the processor 219 can be configured to determine if an actual or potential impact is taking place. For example, one or more sensors 206 can be configured to sense a pressure applied thereto, and the processor can determine if the pressure is indicative of a force capable of injuring an individual, such as by comparing the measured force to a threshold force stored in the memory. The threshold levels (e.g., the impact threshold levels) can be set for any condition, such as the amount of pressure applied or potentially applied thereto, size of object impacting or potentially impacting the supportive member system, velocity of object impacting or potentially impacting the supportive member system, orientation of one or more portions of the supportive members system such as twisting, falling, or bending, an amount of time spent on an activity, a number of previous impacts against the supportive member system, or combinations thereof. The threshold value can be set by the individual, a medical professional, a manufacturer, the controller, or other persons. In an embodiment, the threshold level can include a deployment threshold level that indicates when the controller 208 directs the energy source 216 to deliver the stimulus energy 215 to the active layer 214 (e.g., when the impact will exceed the impact threshold level). In an embodiment, the threshold level can include an injury threshold level that indicates when an actual impact source likely injured the individual.
The processor 219 can compare the sensed characteristics, such as velocity, pressure, proximity, etc., to one or more threshold values to determine that an actual or potential impact is taking place. Responsive to a sensed characteristic (e.g., force, pressure, velocity, proximity, etc.) being beyond the corresponding threshold value, the processor 219 can be configured to direct the energy source 216 to deliver (or stop delivering) the stimulus energy 215 to the active layer 214 to change the active layer from a first state to a second state, or vice versa. For example, the processor 219 directs the energy source 216 to cease delivering or deliver less of the stimulus energy 215 to the active layer when the processor 219 determines that the actual or potential impact is relatively small (e.g., the actual or potential impact exhibits a relatively low force, pressure, etc.) such that the actual or potential impact is below an impact threshold. In another example, the processor 219 directs the energy source 216 to commence delivering or deliver more of the stimulus energy 215 to the active layer when the processor 219 determines that the actual or potential impact is relatively large (e.g., the actual or potential impact exhibits a relatively large force, pressure, etc.) such that the actual or potential impact is above an impact threshold. In an embodiment, the at least one processor 219 can be configured to determine if a potential impact or actual impact is taking place based on a combination of any of the sensed characteristics disclosed herein.
The processor 219 can be configured to determine if a threshold level has been met or exceeded by a differential of one or more sensed characteristics sensed at adjacent sensors of the one or more sensors 206. For example, only a single sensor 206 in a plurality of sensors 206 indicating a specific amount of pressure in a specific region of a protective member 204 can indicate a puncture wound is likely as compared to the same pressure spread out over a larger surface area. Responsive thereto, the processor 219 can direct the energy source 216 to deliver the stimulus energy 215 to the active layer 214 to cause an increase in at least one of the viscosity, hardness, yield strength, ultimate tensile strength, Young's modulus, shear modulus, etc. of the active layer 214 to prevent puncture or blunt force injury. In an embodiment, a threshold level can include a level of pressure applied over a surface area whereby the threshold level corresponds to a force indicative of a possible puncture that would result from a relatively sharp object. In an embodiment, from sensor data from the plurality of sensors 206, the processor 219 can be configured to determine a level of acceleration or deceleration indicative of a force capable of breaking bone of the individual, or a motion and directions thereof (e.g., twisting or bending) indicative of a force capable of damaging a body part of the individual. Suitable threshold levels can be stored in the memory storage medium 218.
The processor 219 can be configured to set or adjust one or more threshold levels (e.g., an impact threshold level) based at least partially on one or more of a velocity of at least one body part of the individual, one or more physiological attributes of the individual (e.g., weight, height, age, health, etc.), a location of the individual within an area (e.g., if the individual is within a playing field), a location of the individual with respect to one or more objects, a time of day, an elapsed time (e.g., the time the individual has been playing or if the individual has been playing for a pre-determined amount of time), a history of impacts to at least a portion of the supportive member or protective member 204 (e.g., a portion housing the sensor sensing current conditions), a history of deployment of the protective member (e.g., to the same portion housing the sensor sensing current conditions), a velocity of the individual (e.g., how fast is a football player running), or an activity level of the individual. That is, the processor 219 can be configured to adjust the threshold levels to compensate for velocity of a person, size of a person wearing the protective garment system, proximity of the individual to adjacent objects, or any other criteria. For example, the processor 219 can decrease the threshold level when the individual has been playing for a relatively long time or when the individual has been subjected to impacts (e.g., selected number of impacts).
In an embodiment, the processor 219 can be configured to search a history of the system 200 to determine when or where the energy source 216 delivered the stimulus energy 215 to the active layer 214. For example, the processor 219 can note a region where multiple impacts have taken place (as determined from multiple deliveries of the energy source) and direct the energy source 216 to deliver the stimulus energy 215 to the active layer 214 (e.g., a distinct region of the active layer 214) to provide added protection from repetitive impacts to the individual in that region.
As discussed above, the controller 208 can include the interface 221. The interface 221 can be configured to communicate with an entity. The entity can include one or more of the individual wearing the supportive member, a user (e.g. medical personnel, physical trainers, coaches, commanding officers, etc.), a computer, a tablet, a mobile computing device (e.g., smart phone), a remote control, etc. The interface 221 can include a screen, an input device, or relay (e.g., transceiver). For example, the interface 221 can relay sensed information signals 217 from the sensors 206 to the processor 219 or memory storage medium 218, and can relay control signals 224 to the energy source 216. In an embodiment, the sensed information signals 217 and control signals 224 can be relayed directly between the processor 219 and sensors 206, the energy source 216, or another component of the system 200. Such sensed information signals 217 or the control signals 224 can be transmitted and received via a wireless connection (e.g., Wi-Fi, infrared, Bluetooth, etc.) or a hardwired connection.
In an embodiment, the interface 221 can include a user interface 225 configured to inform a user or the individual information relating to the system. The user interface 225 can include one or more output devices such as a screen, audio (e.g., chimes), visual (e.g., LED lights) or haptic (e.g., vibration mechanism) indicator and one or more input devices (such as a keyboard, buttons, levers, switches, or dials). The user interface 225 can include a desktop computer, a laptop computer, a tablet computer, a mobile computing device (e.g., smart phone) (e.g., smart phone), a watch, or a remote control. The user interface 225 can be configured to output information to the user and accept input from the user. For example, the user interface 225 can be configured to output or communicate to a user (e.g., individual wearer, medical professional, coach etc.) one or more of previous impacts against the individual, a deployment history of the plurality of inflatable members, sensed motion characteristics, a readiness status of one or more portions of the protective garment system, program instructions, or threshold levels of force applied to the individual. The interface 221 and user interface 225 can be configured to receive one or more of input, instructions, or programming from one or more of the individual, the user, a mobile computing device (e.g., smart phone), a tablet, or a computer device.
In an embodiment, the controller 208 can receive one or more inputs from the user interface 225 that the controller 208 can correlate to an actual or potential impact against the supportive member, the protective member 204, or the individual. For example, the user interface 225 can be operably coupled to or integrated with control electrical circuitry of the controller 208 and can receive one or more inputs directly from the individual wearing the supportive member or from other individuals (e.g., observers, such as coaches, trainers, medical staff, etc.). In an embodiment, the controller 208 can correlate the one or more inputs into a potential or actual impact, and responsive to which the controller 208 can generate one or more signals that can be sent to the energy source 216 to deliver stimulus energy 215 to the active layer 214.
The input can be sent via any suitable input device (e.g., the user interface 225 can include or be connected to one or more of a user, a computing device, a tablet, a mobile computing device (e.g., a smart phone), or a remote control). For example, a personal electronic device (e.g., personal electronic device of the individual) can be operably coupled at the user interface 225 and can send one or more signals or inputs to the controller 208. Additionally or alternatively, one or more buttons, a keyboard, or any other suitable device can be operably coupled to the controller 208 and can send one or more signals thereto.
The protective member 204 can include at least one power source 226 configured to supply electrical power to one or more components of the protective member 204 or the protective garment system. For example, the power source 226 can be operably coupled to at least one of the sensors 206, the controller 208, the energy source 216, another component of the protective member 204, or another component of the system 200. For example, the power source 226 can be disposed in the protective member 204, the controller 208, or another component of the system 200.
In an embodiment, the power source 226 can include a device configured to store power (e.g., electrical power) therein. For example, the power source 226 can include at least one battery (e.g., microbattery) or at least one capacitor. In an embodiment, the power source 226 can include a device that can generate electrical power. For example, the power source 226 can include a fuel cell, an energy harvester, or a transducer. The energy harvester can include any device configured to generate electricity from the environment thereabout, such as solar cells, thermoelectric generators, or piezoelectric generators. In an embodiment, the power source 226 can include a device that is rechargeable. In an embodiment, the power source 226 is replaceable. In an embodiment, the power source 226 is not replaceable or is not rechargeable.
In an embodiment, the power source 226 is at least partially positioned in or on the protective member 204. In an embodiment, the power source 226 is distinct from the protective member 204 and is at least partially positioned in or on the supportive member
In an embodiment, the at least one power source 226 includes a plurality of power sources 226, such as a first power source and a second power source. In an embodiment, the first and second power sources can be substantially the same. In an embodiment, the first and second power sources can be different. For example, the first power source can include a device configured to store energy therein and the second power source can include a device that can generate electricity. In such an example, the second power source can be coupled to the first power source such that the second power source charges the first power source. In an embodiment, the first power source is coupled to a first component (e.g., a first segment) of the protective member 204 and the second power source is coupled to a second component (e.g., a second segment) of the protective member 204 that is different than the first component.
FIG. 3A is a partial cross-sectional view of a protective member 304, according to an embodiment. Except as otherwise described herein, the protective member 304 and its materials, components, or elements can be similar to or the same as the protective member 204 (FIG. 2) and its respective materials, components, or elements. For example, the protective member 304 can be a cross-sectional view of the protective member 204. The protective member 304 or its materials, components, or elements can be used in any of the protective member, supportive member, or system embodiments disclosed herein.
The protective member 304 includes at least one passive layer 312 and at least one active layer 314 coupled to the passive layer 312. The active layer 314 can include an energy-responsive material 332 that changes at least one physical property thereof responsive to at least one electrical stimulus energy. The protective member 304 also includes the at least one energy source 316. The energy source 316 includes at least one electrical energy source 327 configured to deliver the electrical stimulus energy (e.g., electric field) to the energy-responsive material 332. For example, the electrical energy source 327 can include a single electrode, a plurality of electrodes, or one or more pairs of electrodes (e.g., a single pair of electrodes or a plurality of pairs of electrodes) operably coupled to a voltage supply. In the illustrated embodiment, the electrical energy source 327 includes a first electrode 328 and a second electrode 330.
In an embodiment, at least a portion of the energy source 316 is at least partially positioned in or on the passive or active layer 312, 314. For example, the electrical energy source 327 partially forms the passive or active layer 312, 314. In an embodiment, at least a portion of the electrical energy source 327 is distinct from the passive and active layers 312, 314. For example, at least a portion of the electrical energy source 327 can be positioned between the passive and active layers 312, 314, positioned adjacent to (e.g., attached to) a surface of the passive layer 312 spaced from the active layer 314, positioned adjacent to (e.g., attached to) a surface of the active layer 314 spaced from the passive layer 312, spaced from the passive and active layers 312, 314 (e.g., attached to a supportive member that includes the protective member 304), etc.
In an embodiment, the active layer 314 can include one or more at least substantially fluid tight regions 331 configured to store the energy-responsive material. For example, the energy-responsive material 332 can include a fluid. In an embodiment, the active layer 314 can include at least one wall that at least partially defines the at least substantially fluid tight region 331. The at least one wall can be at least partially formed from the electrical energy source 327 (e.g., the first and second electrodes 328, 330) or a separate container. In an embodiment, the at least substantially fluid tight region 331 can include a bundle of fibers (e.g., woven fabric) that are or are not at least partially enclosed by at least one wall. The bundle of fibers can be configured to maintain the energy-responsive material 332 therein via capillary forces. In an embodiment, the at least substantially fluid tight region 331 can exhibit a thickness t that is less than 3 mm, less than 1 mm, less than 0.5, or less than 0.1 mm to reduce the weight of the protective member 304. The energy-responsive material 332 can at least partially fill (e.g., completely fill) the at least substantially fluid tight region 331.
In an embodiment, the energy-responsive material 332 includes at least one electrorheological fluid. The electrorheological fluid can include any suitable electrorheological fluid. For example, the electrorheological fluid can include at least a liquid phase and a solid phase. In an embodiment, the liquid and solid phases can exhibit substantially similar densities to prevent the solid phase from precipitating out of the liquid phase. In an embodiment, the solid phase includes nanoparticles to prevent the solid phase from precipitating out of the liquid phase. In an embodiment, the solid phase includes microparticles. In an embodiment, the electrorheological fluid includes a surfactant or other chemical that prevents the solid phase from precipitating out of the liquid phase. In an embodiment, the liquid phase is an oil, such as silicone oil. In an embodiment, the solid phase includes dielectric particles. In an embodiment, the solid phase includes a conductor coated in an insulator.
In operation, the energy source 316 can switch the electrorheological fluid between at least a first state and a second state. In the first state (e.g., inactive state), the electrorheological fluid exhibits a first physical property. The electrorheological fluid can exhibit the first physical property when the electrical energy source 327 does not apply the electrical stimulus energy to the electrorheological fluid. As such, the first physical property can be the natural viscosity, shear modulus, elastic modulus, yield stress, etc. of the electrorheological fluid because the solid phase is randomly dispersed in the liquid phase.
In the second state (e.g., active state), the electrorheological fluid exhibits a second physical property. The electrorheological fluid may exhibit the second physical property when the electrical energy source 327 applies at least one electrical stimulus energy to the electrorheological fluid. The electrical stimulus energy can include an electric field. Not to be bound by theory, the electrical stimulus energy can cause the solid phase to align therewith. As such, the second physical property can be the increased viscosity, increased shear modulus, increased elastic modulus, increased yield stress, etc. of the electrorheological fluid. As such, the second physical property of the electrorheological fluid can cause the electrorheological fluid to better absorb energy from an impact against the protective member 304 (e.g., increase the force dampening thereof); increase the impact-, indentation-, and tear-resistance thereof; etc. In an embodiment, increasing the magnitude of the electrical stimulus energy delivered to the electrorheological fluid can further increase or decrease the change in the physical property of the electrorheological fluid (e.g., further increase the viscosity thereof). The electrorheological fluid can switch between the second state to the first state by ceasing to deliver the at least one stimulus energy to the electrorheological fluid.
In an embodiment, the at least one energy-responsive material 332 can include at least one electroactive polymer. The electroactive polymer can include any suitable electroactive polymer. For example, the electroactive polymer can include an electric electroactive polymer, an ionic electroactive polymer, a non-ionic electroactive polymer (e.g., a polyvinyl alcohol based polymer), carbon nanotubes, or a conductive polymer. An electric electroactive polymer can include ferroelectric polymers (e.g., poly(vinylidene fluoride), dielectric electroactive polymers, electrostrictive graft elastomers, electro-viscoeleastic elastomers, electrostrictive paper, or liquid crystal elastomer materials. An ionic electroactive polymer includes ionic polymer gels or ionomeric polymer-metal composites (e.g., Nation® (perfluorosulphonate manufactured by Du Pont), Flemion® (perfluorocaboxylate manufactured by Asahi Glass). Conductive polymers include polypyrrole, poly(p-phenylene vinylene), polyaniline, polythiophenes, polyaniline, poly(3,4-ethylenedixythiophene), or poly(3,4-ethylenedioxypyrrole.
In operation, the electrical energy source 327 can switch the electroactive polymer between at least a first state and a second state in substantially the same manner as the electrorheological fluid. For example, in the first state, the electroactive polymer exhibits a first physical property when the electrical energy source 327 does not apply the electrical stimulus energy to the electroactive polymer. As such, the first physical property can be the natural volume, cross-sectional area, density, porosity, shape, etc. of the electroactive polymer. FIG. 3A illustrates the electroactive polymer in the first state.
In the second state (e.g., active phase), the electroactive polymer exhibits a second physical property when the electrical energy source 327 applies the electrical stimulus energy to the electroactive polymer. FIGS. 3B-3D are cross-sectional views of the protective member 304 shown in FIG. 3A while the electroactive polymer thereof is in the second state.
Referring to FIG. 3B, in an embodiment, the electroactive polymer can controllably increase its volume or cross-sectional area responsive to the electrical stimulus energy is delivered thereto. The electroactive polymer can also controllably decrease the density or change the shape thereof. In such an embodiment, the electroactive polymer can be a polymer gel. The second physical property can cause the electroactive polymer to exhibit improved force dampening (e.g., decrease the deceleration of the impact force thereby decreasing the force applied to an individual), better conform to at least one body region of the individual thereby causing the force to be distributed against a larger surface area of the individual, etc.
Referring to FIG. 3C, in an embodiment, the electroactive polymer can controllably decrease its volume or cross-sectional area responsive to the electrical stimulus energy is delivered thereto. The electroactive polymer can also controllably increase the density or change the shape thereof. In such an embodiment, the electroactive polymer can be a dielectric electroactive polymer. The second physical property of the electroactive polymer can cause the electroactive polymer to increase the impact, indentation, and tear resistance thereof, etc.
Referring to FIG. 3D, in an embodiment, the electroactive polymer can controllably change the shape thereof (e.g., elastically or inelastically deform), responsive to the electrical stimulus energy is delivered thereto. In such an embodiment, the electroactive polymer can be an ionic polymer-metal composite. The second physical property can cause the electroactive polymer to exhibit one or more improved force dampening, to better conform to at least one body region of the individual and thereby cause the force to be distributed against a larger surface area of the individual, increase the impact-resistance thereof, increase the indentation-resistance thereof, or increase the tear-resistance thereof, etc.
In an embodiment, increasing the magnitude of the electrical stimulus energy delivered to the electroactive polymer can further increase or decrease the change in the physical property of the electroactive polymer. For example, referring to FIG. 3B, increasing the electrical stimulus energy delivered to the electroactive polymer can cause the electroactive polymer to further increase the volume, thereof. For example, referring to FIG. 3C, increasing the electrical stimulus energy delivered to the electroactive polymer can cause the electroactive polymer to further decrease the volume of the electroactive polymer, etc. For example, referring to FIG. 3D, increasing the electrical stimulus energy delivered to the electroactive polymer can cause the electroactive polymer to further change the shape of the electroactive polymer, etc.
FIG. 4 is a partial cross-sectional view of a protective member 404, according to an embodiment. Except as otherwise described herein, the protective member 404 and its materials, components, or elements can be similar to or the same as the protective member 204, 304 (FIGS. 2-3D) and their respective materials, components, or elements. For example, the protective member 404 can be a cross-sectional view of the protective member 204. The protective member 404 or its materials, components, or elements can be used in any of the protective member, supportive member, or system embodiments disclosed herein.
The protective member 404 includes at least one passive layer 412 and at least one active layer 414 coupled to the passive layer 412. The active layer 414 can include at least one energy-responsive material 432 that changes at least one property thereof responsive to at least one magnetic stimulus energy (e.g., magnetic field), such as a magnetorheological fluid. The protective member 404 can also include the at least one energy source 416. The at least one energy source 416 includes at least one magnetic field source 434 configured to deliver the magnetic stimulus energy to the energy-responsive material 432. The at least one magnetic field source 434 can include a single magnet or a plurality of magnets. In an embodiment, the at least one magnetic field source 434 includes at least one electromagnet include a plurality of coils 436 that generate a magnetic field when a current is passed therethrough from an current supply or at least one permanent magnet.
The magnetic field source 434 can be similar to the electrical energy source 327 (FIG. 3A). For example, the magnetic field source 434 can be at least partially positioned in or on the passive or active layer 412, 414; distinct from the passive and active layers 412, 414; spaced from the passive and active layers 412, 414; or attached to a supportive member that includes the protective member 404. In another example, the active layer 414 can form an at least substantially fluid tight region 431. The region 431 can be at least partially defined by at least one wall 433 and the magnetic field source 434 can form at least a portion, be attached to, or remote from the wall 433. In another example, the region 431 can include a bundle of fibers can be configured to maintain the magnetorheological fluids therein via capillary forces.
In an embodiment, the magnetorheological fluid includes at least a solid phase and a liquid phase. The solid phase can include a plurality of ferromagnetic particles, such as iron particles. In an embodiment, the solid phase can include at least one of micro-ferromagnetic particles having an average grain size of about 1 μm to about 100 μm (e.g., about 1 μm to about 10 μm, 3 μm to 20 μm, about 1 μm to about 3 μm) or nano-ferromagnetic particles having an average grain size less than about 1 μm. In an embodiment, a mixture of the micro-ferromagnetic particles with the nano-ferromagnetic particles can inhibit the solid phase from precipitating out of the liquid phase. In an embodiment, the ferromagnetic particles can include spherical particles that inhibit the solid phase from precipitating out of the liquid phase. In an embodiment, the ferromagnetic particles can include elongated particles that increase the effect the magnetic stimulus energy has on the magnetorheological fluid. In an embodiment, the solid phase can be about 10% to about 80% of the total volume of the magnetorheological fluid (e.g., about 10% to about 20%, about 20% to about 40%, about 40% to about 50%). The liquid phase can include any suitable liquid, such as water or oil. In an embodiment, the magnetorheological fluid can also include a surfactant to prevent the solid phase from precipitating out of the liquid phase.
In operation, similar to the protective member 304 (FIG. 3A), the magnetic field source 434 can switch the magnetorheological fluid between at least a first state and a second state. In the first state (e.g., inactive state), the magnetorheological fluid exhibits a first physical property because the magnetic field source 434 does not apply the magnetic stimulus energy to the energy-responsive material 432. In the second state (e.g., active state), the magnetorheological fluid exhibits a second physical property because the energy source 416 applies the magnetic stimulus energy to the magnetorheological fluid. Not to be bound by theory, the magnetic stimulus energy can cause the solid phase to align therewith. As such, the second physical property can be the increased viscosity, increased shear modulus, increased elastic modulus, increased yield stress, etc. of the energy-responsive material 432. As such, the second physical property of the energy-responsive material 432 can cause the energy-responsive material 432 to exhibit one or more of improved force dampening, increase the impact-resistance thereof, increase the indentation-resistance thereof, or increase the tear-resistance thereof, etc. In an embodiment, increasing the magnitude of the magnetic stimulus energy delivered to the magnetorheological fluid can further increase or decrease the change in the physical property of the magnetorheological fluid (e.g., further increase the viscosity thereof). In an embodiment, the magnetic energy source 434 can switch the magnetorheological fluid from the second state to the first state by ceasing to deliver the magnetic stimulus energy to the magnetorheological fluid.
FIG. 5 is a partial cross-sectional view of a protective member 504, according to an embodiment. Except as otherwise described herein, the protective member 504 and its materials, components, or elements can be similar to or the same as the protective members 204, 304, 404 (FIG. 2-4) and their respective materials, components, or elements. The protective member 504 or its materials, components, or elements can be used in any of the protective member, supportive member, or system embodiments disclosed herein.
The protective member 504 includes at least one passive layer 512 and at least one active layer 514 coupled to the passive layer 512. The active layer 514 includes at least one non-Newtonian fluid. In an embodiment, the non-Newtonian fluid can include at least one of a shear thickening fluid, a shear thinning fluid, a rheopectic fluid, or a thixotropic fluid. In an embodiment, the non-Newtonian fluid can include any fluid that changes at least one of a viscosity thereof when a mechanical energy is applied thereto. The protective member 504 further includes at least one energy source 516 configured to deliver mechanical energy to the non-Newtonian fluid. For example, the energy source 516 can include at least one mechanical actuator 537.
The mechanical actuator 537 can include any device configured to provide at mechanical energy to the non-Newtonian fluid. For example, the mechanical actuator 537 includes at least one piezoelectric actuator configured to deliver vibrational energy to the non-Newtonian fluid. In another example, the mechanical actuator 537 includes a mixer, such as a magnetic mixer, configured to provide mixing (e.g., turbulence) to the non-Newtonian fluid. In another example, the mechanical actuator 537 includes a MEMS or NEMS device configured to deliver mechanical energy to the non-Newtonian fluid. In another example, the mechanical actuator 537 can include a device configured to deliver a shear stress to the non-Newtonian fluid.
Similar to the active layer 314 (FIG. 3A), the active layer 514 can include one or more at least substantially fluid tight regions 531 configured to store the non-Newtonian fluids. For example, the active layer 514 includes at least one wall 533 that at least partially defines the region 531. The mechanical actuator 537 can be at least partially disposed in the region 531, at least partially disposed in or incorporated into the wall 533, attached to the wall 533, or spaced from the region 531 and the wall 533. In an embodiment, the region 531 can include a bundle of fibers can be configured to maintain the non-Newtonian fluids therein using capillary forces
In operation, similar to the protective member 304 (FIG. 3A), the mechanical actuator 537 can switch the non-Newtonian fluid between at least a first state and a second state. In the first state (e.g., inactive state), the non-Newtonian fluid exhibits a first physical property because the mechanical actuator 537 does not deliver the mechanical stimulus energy thereto. In the second state (e.g., active state), the non-Newtonian fluid exhibits a second physical property because the mechanical actuator 537 delivers the mechanical stimulus energy thereto. In an embodiment, the second physical property can be an increased viscosity, an increased shear modulus, an increased elastic modulus, an increased yield stress, etc. (e.g., shear-thickening fluid, rheopectic fluid). In an embodiment, the second physical property can be a decreased viscosity, a decreased shear modulus, a decreased elastic modulus, a decreased yield stress, etc. (e.g., shear-thinning fluid, thixotropic fluid). As such, the second physical property can cause the active layer 514 to exhibit one or more of better force dampening, increase the impact resistance thereof, increase the indentation resistance thereof, increase the tear resistance thereof, cause the protective member 504 to better form to at least one body region on an individual, etc. In an embodiment, increasing the magnitude of the mechanical stimulus energy delivered to the non-Newtonian fluid can further increase or decrease the change in the physical property of the non-Newtonian fluid (e.g., further increase the viscosity thereof). In an embodiment, the mechanical actuator 537 can switch the non-Newtonian fluid between the second state to the first state by ceasing to deliver the mechanical stimulus energy thereto.
FIG. 6A is a partial cross-sectional view of a protective member 604, according to an embodiment. Except as otherwise described herein, the protective member 604 and its materials, components, or elements can be similar to or the same as the protective members 204, 304, 404, and 504 (FIGS. 3-5) and their respective materials, components, or elements. For example, the protective member 604 can be a cross-sectional view of the protective member 204. The protective member 604 or its materials, components, or elements can be used in any of the protective member, supportive member, or system embodiments disclosed herein.
The protective member 604 includes at least one passive layer 612 and at least one active layer 614 coupled to the passive layer 612. The active layer 614 includes at least one energy-responsive material 632 that is configured to change one physical property thereof responsive to at least one mechanical stimulus energy. The energy-responsive material 632 can include one or more auxetic materials, such as one or more auxetic fibers. The protective member 604 can also include at least one energy source 616 configured to deliver the mechanical stimulus energy to the energy-responsive material 632. For example, the energy source 616 can include at least one mechanical actuator 637.
The auxetic material can include any material that exhibits a negative Poisson's ratio. For example, the auxetic material can include any material that, when stretched in a first direction (e.g., length-wise direction), extends in one or more second directions (e.g., width-wise direction). For example, the auxetic material can include any material that, when compressed in a first direction (e.g., length-wise direction), compresses in one or more second directions (e.g., width-wise direction). In an embodiment, the auxetic material can include any suitable structure that provides the auxetic material the negative Poisson's ratio. For example, the structure can include at least one of a macrostructure, a microstructure, a nanostructure, or a molecular structure. For example, the structure can include at least one of a reentrant structure, a rotating structure, a hinged structure, or another suitable structure. The auxetic material can be formed from a polymer (e.g., polyurethane foam, polyethylene foam), a composite (e.g., anisotropic composites), metals, or another suitable material.
The energy source 616 can include any mechanical actuator 637 that causes the auxetic material to expand, contract, vibrate, or otherwise impart at least one mechanical stimulus to the energy-responsive material 632. For example, the energy source 616 can include the same or similar devices as the mechanical actuator 537 (e.g., FIG. 5). In another example, the mechanical actuator 637 can include a device that applies a tensile stress or a compressive stress to the auxetic material, such as a piezoelectric or shape memory actuator that is physically attached or otherwise coupled to the auxetic material. In an embodiment, at least a portion of the mechanical actuator 637 is at least partially positioned in or on the active layer 614. As such, the mechanical actuator 637 can directly apply the mechanical stimulus energy to the energy-responsive material 632. In an embodiment, at least a portion of the mechanical actuator 637 can be at least partially positioned in or on the passive layer 612. In an embodiment, at least a portion of the mechanical actuator 637 can be spaced from the active layer 614 and the passive layer 612. As such, the mechanical actuator 637 can indirectly deliver the stimulus energy to the energy-responsive material.
In operation, the mechanical actuator 637 can switch the energy-responsive material 632 between at least two of a first, second, or third state. In the first state (e.g., inactive state), the energy-responsive material 632 exhibits a first physical property because the mechanical actuator 637 does not apply the mechanical stimulus energy to the auxetic material. As such, the first physical property can be the natural volume, density, cross-sectional area, shape, porosity, etc. of the energy-responsive material 632.
In the second state (e.g., first active state), the energy-responsive material 632 exhibits a second physical property because the mechanical actuator 637 applies a first mechanical stimulus to the energy-responsive material 632. FIG. 6B is a cross-sectional view of the energy-responsive material 632 in the second state, according to an embodiment. The first mechanical stimulus energy can cause the energy-responsive material 632 to expand in at least one direction. As such, the second physical property can be an increased volume, decreased density, increased cross-sectional area, modified shape, increased porosity, etc. of the energy-responsive material 632. As such, the second physical property can cause the active layer 614 to exhibit better force dampening, better conformation to at least one body region of the individual thereby causing the force to be distributed against a larger surface area of the individual, etc. In an embodiment, increasing the magnitude of the mechanical stimulus energy delivered to the auxetic material can further increase or decrease the change in the physical property of the auxetic material (e.g., further increase the volume thereof). The mechanical actuator 637 can switch the auxetic material from the second state to the first state by ceasing to deliver the first mechanical stimulus energy thereto.
In the third state (e.g., second active state), the energy-responsive material 632 exhibits a third physical property because the mechanical actuator 637 delivers a second mechanical stimulus energy to thereto. FIG. 6C is a cross-sectional view of the energy-responsive material 632 in the third state, according to an embodiment. The second mechanical stimulus energy can cause the auxetic material to contract in at least one direction. As such, the third physical property can be a decreased volume, increased density, decreased cross-sectional area, modified shape, decreased porosity, etc. of the auxetic material. As such, the third physical property can cause the active layer 614 to increase one or more of the impact, indentation, or tear resistance thereof, etc. In an embodiment, increasing the magnitude of the mechanical stimulus energy delivered to the auxetic material can further increase or decrease the change in the physical property of the auxetic material (e.g., further decrease the volume thereof). The mechanical actuator 637 can switch the energy-responsive material 632 from the third state to the first state by ceasing to deliver the second mechanical stimulus to the auxetic material. The mechanical actuator 637 can switch the auxetic material from the third state to the second state by delivering the first mechanical stimulus energy to the auxetic material instead of the first mechanical stimulus energy, or vice versa.
While the energy-responsive materials disclosed herein are mainly disclosed as being at least one of an electrorheological fluid, an electroactive polymer, a magnetorheological fluid, a non-Newtonian fluid, or an auxetic material, it is understood that any suitable energy-responsive material that includes a material that changes at least one property thereof responsive to at least one stimulus energy can be used. For example, the energy-responsive material can include an energy-responsive material that changes at least one property thereof responsive to at least one of thermal energy, electromagnetic energy, or another suitable type of energy.
The protective members disclosed herein can include more than just two layers. FIG. 7 is a cross-sectional schematic view of a portion of a protective member 704 that includes three layers, according to an embodiment. Except as otherwise described herein, the protective member 704 and its materials, components, or elements can be similar to or the same as the protective members 204, 304, 404, 504, 604 (FIGS. 2-6C) and their respective materials, components, or elements. The protective member 704 or its materials, components, or elements can be used in any of the protective member, supportive member, or system embodiments disclosed herein.
The protective member 704 includes a first layer 738, a second layer 740 coupled to the first layer 738, and a third layer 742 spaced from the first layer 738 and coupled to the second layer 740. In an embodiment, the first layer 738 can be closer to an individual wearing a supportive member that includes the protective member 704 than the third layer 742. In an embodiment, at least one of (e.g., at least two of) the first, second, or third layers 738, 740, and 742 can be any of the active layers disclosed herein and the remaining first, second, or third layers 738, 740, 742 can be any of the passive layers disclosed herein.
Forming the protective member 704 from three layers can increase the designability and functionality of the protective member 704. In an embodiment, the first and third layers 738 and 742 can be passive layers and the second layer 740 can be an active layer. For example, the first layer 738 can be a passive layer configured to improve the comfort of the protective member 704, the second layer 740 can be an active layer configured to improve the force dampening of the protective member 704, and the third layer 742 can include a passive layer configured to improve the tear-, impact-, or indentation-resistance of the protective member (e.g., the third layer 742 includes Kevlar). In another example, the first layer 738 and the third layer 742 can be electrodes configured to deliver at least one electrical energy to the second layer 740. In another example, the first layer 738 and the third layer 742 can be configured to appear as normal clothing thereby hiding the presence of the second layer 740.
In an embodiment, at least two of the first, second, or third layers 738, 740, 742 can be active layers. For example, one of the active layers can be configured to prevent injury from a relatively blunt impact source (e.g., improved force dampening, better conform to at least one body region of an individual) while the other active layer can be configured to prevent injury from a relatively sharp impact source (e.g., improved tear-, impact-, indentation-resistance).
While only three layers are illustrated, it is understood that the protective member 704 can include additional layers. For example, the protective member 704 can include 4, 5, 6, 7, 8, 9, 10, or more than 10 layers, depending on the embodiment. It is also understood that active layers and the passive layers can be distributed in the protective member 704 in any suitable arrangement. For example, an active or passive layer can be the layer most proximate the individual. In another example, an active or passive layer can be the layer most remote from the individual. In another example, a passive layer can be directly coupled to two active layers, one active layer and another passive layer, or two other passive layers. In another example, an active layer can be directly coupled to two passive layers, one passive layer and another active layer, or two other active layers. In another example, the protective member 704 can have the same number of active and passive layers, more passive layers than active layers, or more active layers than passive layers.
In an embodiment, any of the protective members disclosed herein can be formed from a single unit. In an embodiment, any of the protective members disclosed herein can be formed from a plurality of segments instead of a single unit. FIG. 8A is a top view of a protective member 804 a that includes a plurality of segments 844 a, according to an embodiment. Except as otherwise described herein, the protective member 804 a and its materials, components, or elements can be similar to or the same as the protective members 204, 304, 404, 504, 604, 704 (FIGS. 3-7) and their respective materials, components, or elements. The protective member 804 a or its materials, components, or elements can be used in any of the protective member, supportive member, or system embodiments disclosed herein.
The protective member 804 a includes at least one active layer and at least one passive layer. One or more of the at least one active layer or the at least one passive layer can be formed from a plurality of segments 844 a. In the illustrated embodiment, at least a top layer 846 a (e.g., an exterior or interior surface) of the protective member 804 a is formed from the segments 844 a. For example, the segments 844 a only form the top layer 846 a. In another example, the segments 844 a form the top layer 846 a and one or more additional layers of the protective member 804 a. In an embodiment, the plurality of segments 844 a form one or more layers of the protective member 804 a that are each distinct from the top layer 846 a. In an embodiment, at least one of the segments 844 a can be replaceable. For example, at least one of the segments 844 a can be detached from the rest of the protective member 804 a after the segment 844 a is activated or damaged. A replacement segment can be added to the protective member 804 a to replace the segment 844 a that is removed from the protective member 804 a.
The segments 844 a are positioned such that at least some of the segments 844 a are positioned at least substantially proximate to (e.g., contact) an immediately adjacent segment 844 a. In an embodiment, at least some of the segments 844 a can each exhibit one or more shapes or one or more sizes, and together are arranged to form a substantially continuous layer. For example, the substantially continuous layer can have substantially no gaps between each of the segments 844 a when the continuous layer is not bent, twisted, stretched, or otherwise deformed. In an embodiment, at least some of the segments 844 a can each exhibit one or more shapes or one or more sizes, or are arranged so as to form a discontinuous layer (e.g., at least some of the segments 844 a define gaps therebetween). For example, each of at least some of the segments 844 a can exhibit a generally octagonal shape and when consolidated, they define generally rectangular gaps therebetween. In an embodiment, each of the plurality of segments 844 a can exhibit at least one of a generally circular shape, a generally elliptical shape, a generally triangular shape, a generally rectangular shape, a generally pentagonal shape, a generally hexagonal shape, a generally octagonal shape, a generally polygonal shape, or any other suitable shape. For example, each of the plurality of segments 844 a can exhibit a generally triangular shape and some of the plurality of segments 844 a can be reversed relative to the remaining segments 844 a to form a generally triangular grid-like pattern. In an embodiment, the plurality of segments 844 a can be arranged to form at least one of a generally circular shape, a generally elliptical shape, a generally triangular shape, a generally rectangular shape, a generally pentagonal shape, a generally hexagonal shape, a generally octagonal shape, another suitable polygonal shape, or any other suitable shape. In an embodiment, at least some of the segments 844 a comprise distinct units. In an embodiment, at least some of the segments 844 a each exhibit one or more shapes or one or more sizes, or are arranged so as increase flexibility of protective member 804 a. For example, the plurality of segments 844 a can include at least one first segment and at least one second segment, wherein the first segment exhibits a shape or size that is different than the second segment.
In an embodiment, the segments 844 a can additionally form part of a passive layer. In such an embodiment, the flexibility of protective member 804 a can be improved, the protective member 804 a can better conform to at least one body region of an individual, etc., compared to a protective member that includes a passive layer that is not formed from a plurality of segments.
In an embodiment, the segments 844 a can form at least a portion of an active layer. In such an embodiment, one or more of the segments 844 a each includes an energy-responsive material, and each of the one or more segments 844 a can be selectively activated. For example, an impact source may impact or may be predicted to impact a selected portion of the protective member 804 a. In such an example, only the segments 844 a that are at or near the actual impact or predicted impact location are activated. Activating only a portion of the segments 844 a can improve the efficiency of (e.g., decrease energy used by) the protective member 804 a. Similarly, activating only a portion of the plurality of segments 844 a can increase the flexibility of the portions of the protective members that are not activated. Additionally, forming an active layer with the plurality of segments 844 a can add redundancies into the protective member 804 a. For example, if one of the segments 844 a is unable to activate (e.g., damaged), other segments 844 a thereabout can activate. In an embodiment, each of the segments 844 a can include at least two layers (e.g., at least one passive layer and at least one active layer).
In an embodiment, at least two of the segments 844 a can be communicably coupled together. For example, a first segment can sense one or more characteristics and communicate the sensed characteristics to a second segment. In another example, a controller 808 a can be disposed in or on a first segment and the controller 808 a can be configured to communicate with and at least partially control a second segment (e.g., the second segment does not include a controller). Each of the segments 844 a that are communicably coupled together can be wiredly or wirelessly communicably coupled together, can each include a transceiver (e.g., a receiver or a transmitter), etc.
At least one of the segments 844 a can be communicably coupled to and at least partially controlled by at least one controller 808. For example, the controller 808 can be communicably coupled to and at least partially control one or more components of just one of, at least some of, or all of the segments 844 a. The controller 808 can be similar to or the same as the controller 208 (FIG. 2). For example, the controller 808 can be at least partially positioned in or on, spaced from, or distinct from the protective member 804 a. For instance, the controller 808 can be at least partially positioned in or on at least one of the segments 844 a. In an embodiment each of the segments 844 a is coupled to and at least partially controlled by a distinct controller 808.
In an embodiment, the at least one controller 808 can include a plurality of controllers 808 that operate at least partially independently from each other. For example, at least some of the controllers 808 can be communicably coupled together. In particular, each of the controllers 808 that are communicably coupled together can include a transceiver (e.g., in the interface 221 of FIG. 2) that enables the controllers to receive or transmit one or more signals therebetween. The signals can include at least one of one or more operational instructions, one or more information signals, one or more sensed information signals (e.g., a signal indicating deployment of an adjacent segment 844 a), one or more control signals (e.g., one of the controllers 808 can at least partially control the operation of another controller 808), one or more programs, etc. In another example, one of the controllers 808 can be communicably coupled to and at least partially control the operation of at least one of the segments 844 a. In another example, one of the segments 844 a can be communicably coupled to and at least partially controlled by at least one of the controller 808. In another example, at least some of the segments 844 a can include at least one of the controllers 808 at least partially positioned therein. For instance, a controller 808 can at least partially control the operation of the segment 844 a that includes the controller 808 or at least one segment 844 a distinct from the segment 844 a that includes the controller 808.
In an embodiment, at least one of the segments 844 a can include at least one energy source 816 at least partially positioned therein or communicably coupled and spaced therefrom. The energy source 816 can be configured to deliver at least one stimulus energy to an energy-responsive material of the segment 844 a that includes the energy source 816 or at least one segment 844 a that is distinct from the segment 844 a that includes the energy source 816. For example, the energy source 816 that is disposed in or on a segment 844 a can be configured to deliver at least one stimulus energy to an energy-responsive material of the same segment 844 a responsive to a dedicated controller 808 that is also disposed in or on the same segment 844 a.
In an embodiment, at least one of the segments 844 a can include at least one power source 826 at least partially positioned therein or communicably coupled and spaced therefrom. The power source 826 can be configured to deliver energy to one or more components of the segment 844 a that includes the power source 826 or at least one segment 844 a that does not include the power source 826.
In an embodiment, at least one of the segments 844 a can include one or more sensors 806 at least partially positioned therein or spaced therefrom. The sensors 806 can sense one or more characteristics associated with at least one of the segments 844 a (e.g., the segment 844 a that includes the sensor 806). For example, the sensors 806 can sense impact against or one or more potential impact sources proximate to the segment 844 a. The sensors 806 can transmit one or more sensed information signals to one or more controllers 808, for example a dedicated controller 808 of the same segment 844 a. In an embodiment each segment 844 a includes an energy-responsive material, at least one dedicated controller 808, and at least one dedicated sensor 806.
In an embodiment, at least one of the segments 844 a can be configured to be a unit that acts independently of the other segments 844 a (“independent segment”). For example, the independent segment can include one or more dedicated sensors 806, a dedicated energy source 816, a dedicated power source 826, or at least one dedicated controller 808 at least partially disposed therein or thereon. For instance, the dedicated controller 808 can direct the dedicated energy source 816 to activate the energy-responsive material of the independent segment responsive to the dedicated sensors 806 sensing an actual or potential impact against the independent segment. In an embodiment, a plurality of independent segments (e.g., at least some of or all of the segments 844 a) can each be configured to be a unit that acts independently of the other segments 844 a. In such an embodiment, the plurality of independent segments can form at least a portion of the protective member 804 a.

For instance, the user interface 1025 can indicate if one or more protective members 1004 b of at least one of the supportive members 1010 b, 1010 b′, 1010 b″ are functioning or if one or more of the protective members 1004 b, 1004 b′, 1004 b″ are not functioning properly (e.g., need repair, a power source requires charging, etc.).
In an embodiment, the CCU 1054 can provide one or more recommendations based on a threshold having been met or exceeded. In an embodiment, the CCU 1054 can provide one or more recommendations that an individual wearing at least one of the supportive members 1010 b, 1010 b′, 1010 b″ should be removed to a safe location, removed from an athletic event, or medical assistance may be required. The one or more recommendations can be based on whether one or more threshold levels (e.g., an injury threshold level or an impact threshold level) have been met or exceeded. The threshold level can be a selected likelihood that an individual wearing at least one of the supportive members 1010 b, 1010 b′, 1010 b″ was injured from an actual impact or a potential impact (e.g., the CCU 1054 provides the one or more recommendations before the actual impact). The CCU 1054 can determine that at least one threshold level has been met or exceeded based on the sensed information signals received by the CCU 1054 from the sensors 1006. The sensed information signals can include any of the characteristics disclosed herein, such as a force applied to at least one of the supportive members 1010 b, 1010 b′, 1010 b″, a radius of curvature of the impact source, a motion (e.g., speed, direction, location, acceleration, deceleration) of at least one of the supportive members 1010 b, one or more sensed characteristics of an individual (e.g., heartrate), etc.
In an embodiment, the threshold level can be a selected likelihood that an actual impact punctured an individual wearing at least one of the supportive members 1010 b, 1010 b′, 1010 b″. For example, the threshold level can be determined based on at least the force of the impact and the radius of curvature of the impact source. In an embodiment, the threshold level can be the likelihood that an actual impact broke or fractured a bone of an individual wearing at least one of the supportive members 1010 b, 1010 b′, 1010 b″. For example, the threshold level can be determined based on at least a location on the individual that is impacted and a force applied to the location. In an embodiment, the threshold level can be the likelihood that an actual impact damaged a body part (e.g., ruptured spleen, concussion, fractured a joint, contusion, etc.) of an individual wearing at least one of the supportive members 1010 b, 1010 b′, 1010 b″. For example, the threshold level can be determined based on at least a location on the individual that is impacted and a force applied to the location.
The threshold level can be when an actual impact has a likelihood of less than 1%, 1%, 2%, 3%, 4%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 60%, 70%, 75%, 80%, 90%, 95%, or about 100% of causing an injury, including ranges between any of the percentages. In an embodiment, the threshold level is predetermined and is stored on a memory storage medium (e.g., memory storage medium 218 in FIG. 2) of the CCU 1054. In an embodiment, the threshold level is determined based on information stored on the memory storage medium. For example, the threshold level can be determined at least partially based on an individual's medical history. In an embodiment, the threshold level can vary. For example, an impact that can cause a severe injury to an individual can have a lower threshold level (e.g., lower likelihood of injury) than an impact that can cause a minor injury. In another example, the threshold level may vary based on a time of day, an activity of an individual wearing at least one of the supportive members 1010 b, 1010 b′, 1010 b″, etc.
In an embodiment, the CCU 1054 can provide one or more recommendations that at least a portion of at least one of the supportive members 1010 b, 1010 b′, 1010 b″ (e.g., a segment of at least one of the supportive members 1010 b, 1010 b′, 1010 b″) needs to be replaced. The one or more recommendations can be based on whether one or more impact threshold levels have been met or exceeded. The CCU 1054 can determine that at least one impact threshold level has been met or exceeded based on the sensed information signals received by the CCU 1054 from the sensors 1006. The sensed information signals can include any of the characteristics disclosed herein, such as a force applied to at least one of the supportive members 1010 b, 1010 b′, 1010 b″, the number of times at least a portion of the supportive member 1010 b, 1010 b′, 1010 b″ has deployed, or the length of time the supportive members 1010 b, 1010 b′, 1010 b″ has been in use.
In an embodiment, a threshold level is predetermined and is stored on the memory storage medium 1018. In an embodiment, the threshold level is determined based on information stored on the memory storage medium 1018. For example, the threshold level can be determined at least partially based on an individual's medical history. In an embodiment, the threshold level can vary. For example, an impact that can cause or lead to a severe injury to an individual can have a lower threshold level (e.g., lower likelihood of injury) than an impact that can cause a minor injury. In another example, the threshold level may vary based on a time of day, an activity of an individual wearing the supportive member 1010 b, 1010 b′, 1010 b″, etc.
In an embodiment, at least one of the supportive members 1010 b, 1010 b′, 1010 b″ can be configured to determine a threshold level and to alert an individual wearing the supportive member 1010 b, 1010 b′, 1010 b″ that the threshold level has been met or exceeded. For example, at least one controller of the supportive member 1010 b, 1010 b′, 1010 b″ can be configured to determine whether the threshold level has been met or exceeded at least partially based on one or more sensed information signals received by the controller. The supportive member 1010 b, 1010 b′, 1010 b″ can include a user interface configured to alert the individual or another entity when the threshold level has been met or exceeded. For example, the device can include a speaker that emits a sound when the threshold level has been met or exceeded. In such an embodiment, the CCU 1054 can be omitted.
Furthermore, in an embodiment, any of the controllers (e.g., controller 1008) or sensors 1006 can transmit information or data to one or more data storage devices or systems that can be associated with or can include medical records (e.g., medical records of the individual wearing the supportive member(s)). For example, the controller can store or transmit data related to the number and severity of impacts received by an individual (e.g., impact force imparted onto the individual, impact energy absorbed by the individual, location(s) of impact(s), etc.). In an embodiment, the medical records of the individual can be associated with or can receive information related to the impact(s) to assess effects of the impact(s) on the health of the individual, to assess whether the individual may need to seek medical attention, etc.

In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent that, based upon the teachings herein, changes and modifications can be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. In general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims can contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). Virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
With respect to the appended claims, any recited operations therein can generally be performed in any order. Examples of such alternate orderings can include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. With respect to context, even terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
While various aspects and embodiments have been disclosed herein, the various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
