DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

[0040] Before turning to the figures, which illustrate certain embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.

[0041] Measuring the temperature of a subject (e.g., a human, an animal, etc.) may provide valuable insight while assessing the subject’s health. For example, a thermometer may be used by a user to measure the body temperature of the subject. Further, the thermometer may display the temperature to the user of the thermometer.

[0042] Referring generally to the figures, thermometer devices are disclosed. According to various example embodiments, a thermometer may be configured to measure the subject’s body temperature by measuring an external temperature of the subject. For example, a thermometer may be configured to measure the temperature of the subject’s skin. The thermometer may include a temperature sensor that is configured to measure infrared (IR) radiation being emitted from the subject such that the temperature sensor can measure the subject’s temperature without physically contacting the subject with the thermometer.

[0043] The thermometer devices described herein may further be configured to measure the subject’s body temperature by measuring an internal temperature of the subject. For example, the thermometer devices described herein may include one or more attachments that are configured to be inserted into the subject (e.g., the ear, the mouth, the rectum, the vagina, etc.). For example, the thermometer devices described herein may include a basal attachment configured to be inserted into the subject. The basal attachment may include a tip that is configured to conduct heat from the subject such that the temperature sensor included in the thermometer device is able to measure the temperature of the tip. Further, the basal attachment may include a temperature sensor (e.g., a basal attachment temperature sensor) on or within a body of the basal attachment. In this example embodiment, the temperature sensor included on the basal attachment may communicate temperature readings to the thermometer device that is coupled to the basal attachment.

[0044] The thermometer may include an ear attachment configured to be inserted into the ear subject to detect a temperature within an ear. For example, the ear attachment may include an opening that is configured to allow IR radiation to pass from the inner ear of the subject, through the opening, and towards the temperature sensor such that the subject’s temperature may be measured. In another example, the ear attachment includes a temperature sensor (e.g., an ear attachment temperature sensor) on or within a body of the ear attachment. In this example embodiment, the temperature sensor included on the ear attachment may communicate temperature readings to the thermometer device that is coupled to the ear attachment.

[0045] According to various embodiments, the ear attachment can be used to take a temperature reading from within an ear without being inserted into the ear. It should be appreciated that the ear attachment and the basal attachment are two example attachments, and that the thermometer devices described herein may be used in conjunction with other types of attachments (e.g., a mouth specific oral attachment, a pacifier attachment, a temporal artery attachment, etc.). [0046] According to various example embodiments, a single thermometer device may include one or more attachments described herein such that the thermometer device may be used to measure a subject’s temperature in a variety of locations.

[0047] Referring now to FIGS. 1 and 2, a thermometer device 100 is shown according to an example embodiment. The thermometer device 100 is configured to measure and indicate a temperature (e.g., the temperature of a subject). The thermometer device 100 may be a digital thermometer configured to measure the subject’s temperature using a temperature sensor and display the subject’s temperature via a display device, as is discussed further herein.

[0048] The thermometer device includes a body that extends from a thermometer first end 102 to a thermometer second end 104. The distance between the thermometer first end 102 and the thermometer second end 104 defines a length of the thermometer device 100.

According to various embodiments, the length of the thermometer device 100 may be adjusted. For example, the thermometer device 100 may be configured to translate between a collapsed orientation (e.g., as shown in FIG. 1) and an extended orientation (e.g., as shown in FIG. 2).

[0049] According to various embodiments, changing the orientation of the thermometer device 100 may cause one or more attributes of the thermometer device 100 to change. For example, the thermometer device 100 may power on or power off when the thermometer device 100 transforms from the collapsed orientation to the extended orientation. Further, the thermometer device 100 may power on or power off when the thermometer device 100 transforms from the extended orientation to the collapsed orientation.

[0050] As shown, the thermometer device 100 includes a first portion 110 and a second portion 120. According to various embodiments, the first portion 110 is configured to translate relative to the second portion 120. For example, when the thermometer device 100 transforms from the collapsed position to the extended position, the first portion 110 may translate away from the second portion 120. For example, a third portion 112 may couple the first portion 110 to the second portion 120 such that the first portion 110 and the second portion 120 can translate relative to one another.

[0051] As shown, the thermometer device 100 includes an activation device, shown as a power button 130. The power button 130 is configured to power on and/or power off the thermometer device 100. For example, the thermometer device 100 may power on in response to the power button 130 being depressed by a user. According to various embodiments, the thermometer device 100 may include a touch sensor 132 (e.g., a capacitive touch sensor). The touch sensor 132 is configured to detect the touch of a user. The touch sensor 132 may be proximate the power button 130. For example, as shown, the touch sensor 132 surrounds the power button 130. According to various embodiments, the thermometer device 100 may only be powered on or powered off in response to the touch sensor 132 detecting a touch of a user or another conductive object and the power button 130 being depressed. For example, the touch sensor 132 may not detect a touch if a non- conductive object (e.g., a carrying case) contacts the touch sensor 132. Therefore, if the power button 130 is incidentally depressed by a non-conductive object, the thermometer device 100 may not be powered on because the touch sensor 132 did not detect a conductive object (e.g., a finger) at the same time the power button 130 is depressed. Such an arrangement may reduce the chances of incidental powering on or powering off of the thermometer device 100, which may conserve battery power.

[0052] As shown in FIG. 2, the thermometer device 100 includes a charging port 140. For example, the thermometer device 100 may be battery powered (e.g., a lithium ion rechargeable battery). The charging port 140 may be configured to receive a charging cable such that the device may be charged. As shown, the charging port 140 is exposed while the thermometer device 100 is in the extended orientation shown in FIG. 2 and the charging port 140 is concealed while the thermometer device 100 is in the collapsed orientation shown in FIG. 1. According to various embodiments, such an arrangement may enable the thermometer device 100 to be more compact when not charging. Further, this arrangement may protect the charging port 140 from undesirable debris when the thermometer device 100 is in the collapsed orientation.

[0053] Referring now to FIG. 3 A, a front view of the thermometer device 100 is shown. As shown, the thermometer device 100 includes a temperature sensor 136 proximate the thermometer second end 104. The temperature sensor 136 is positioned within an opening 152 in the body of the thermometer device 100. The opening 152 may include a funnel- shaped wall in addition to an aperture near the bottom of the funnel. The temperature sensor 136 may include an IR sensor configured to detect a temperature of a subject through the opening 152 (e.g., through the aperture) without physically contacting the subject. Such an arrangement may allow the thermometer device 100 to be used across multiple subjects without the need to sanitize the thermometer device 100 between subjects because the subjects do not physically contact the thermometer device 100.

[0054] According to various embodiments, the temperature sensor 136 may include an IR filter lens. For example, the IR filter lens may be configured to prevent or reduce indirect IR radiation from being detected by the temperature sensor 136. For example, the IR filter lens may be polarized such that only IR radiation coming directly at the temperature sensor 136 is detected and IR radiation being emitted from outside the desired field of view is not detected by the temperature sensor 136.

[0055] As shown in FIG. 3 A, the thermometer device 100 includes a proximity sensor 138. The proximity sensor 138 is configured to measure a distance between the subject and the proximity sensor 138. According to various embodiments, the thermometer device 100 is configured to alert a user (e.g., via a display screen 142 shown in FIG. 3B) in response to the subject being outside of a desired range of distance from the proximity sensor 138. For example, the temperature sensor 136 may be optimized to detect a temperature when the thermometer device 100 is a predetermined distance from the subject. As such, the proximity sensor 138 may alert the user if the thermometer device 100 is outside of an acceptable range that is determined based on the predetermined distance. Such an arrangement may result in more accurate temperature measurements. According to various embodiments, the proximity sensor 138 is an IR based sensor.

[0056] In various embodiments, the temperature displayed by the thermometer device 100 may depend on both the temperature measured by the temperature sensor 136 and a distance measured by the proximity sensor 138. For example, the thermometer device 100 may receive a first temperature reading from the temperature sensor 136 and adjust the first temperature based on the distance measured by the proximity sensor 138 (e.g., by utilizing a lookup table). The thermometer device 100 then displays a second temperature, different from the first temperature, which is based on the first temperature and the distance measured by the proximity sensor 138.

[0057] Referring now to FIG. 3B, a rear view of the thermometer device 100 is shown. As shown, the thermometer device 100 includes a display screen 142. The display screen 142 is configured to display information to a user of the device, such as a temperature of the

-lo subject, a notification that the thermometer device 100 is too far from the subject, a battery level indicator 144, etc. According to various embodiments, the display screen 142 includes a color screen that is configured to change colors based on one or more measurements. For example, if a measured temperature is below a first threshold, the display screen 142 may change to blue. If a measured temperature is above a second threshold, the display screen 142 may change to red. If a measured temperature is between the first threshold and the second threshold, the display screen 142 may turn to green. Other colors may be exhibited under various conditions according to various embodiments.

[0058] According to various embodiments, the thermometer device 100 is configured to receive one or more user inputs (e.g., via the display screen 142, via a connected external device, etc.). For example, a user may input one or more characteristics of a subject (e.g., name, age, sex, weight, etc.). The thermometer device 100 may alter the output measurements based on the one or more characteristics. Further, the thermometer device 100 may store data, or cause data to be stored on an external device, associated with one or more user profiles. The user profiles may be defined by the one or more characteristics of the subject that are input by the user.

[0059] Referring now to FIG. 4A, an exploded view of the thermometer device 100 is shown. As shown, the thermometer device includes a light 146 configured to be positioned within the body of the thermometer device 100. The light 146 is configured to provide lighting proximate the thermometer second end 104. For example, the light 146 may provide illumination in a direction that the thermometer second end 104 is pointed. The illumination may improve visibility for a user, which may be particularly useful when using the thermometer device 100 with one or more of the attachments described herein. For example, the light 146 may illuminate a subject’s ear when an ear attachment is coupled to the thermometer device and the ear attachment is pointed towards the subject’s ear. According to various embodiments, the light 146 may be powered on in response to an attachment being coupled to the thermometer device 100. Further, the light 146 may be powered off in response to an attachment being decoupled from the thermometer device 100.

[0060] As shown, the thermometer device 100 includes a circuit board 148 configured to facilitate communication between two or more electrical components. For example, the circuit board 148 may couple a processor to a wireless communication circuit that is configured to enable communication (e.g., Bluetooth, Wi-Fi, cellular, etc.) between the thermometer device 100 and one or more external devices (e.g., a cell phone, a central computing system, etc.). The wireless communication circuit may send data from the thermometer device 100 to an external device and receive user inputs from an external device.

[0061] Referring now to FIG. 4B, an exploded view of another thermometer device 200 is shown, according to an example embodiment. The thermometer device 200 may share one or more features with the thermometer device 100 described herein. For example, the thermometer device 200 is shown to include a first portion 210, a second portion 220, a third portion 212, an opening 252 in the body, a proximity sensor 238, a temperature sensor 236, a power button 230, a touch sensor 232, a light 246, a charging port 240, a display 242, and a circuit board 248 that are similar or the same as the corresponding components of the thermometer device 100.

[0062] As shown in FIG. 4B, the thermometer device 200 includes a thermometer coupler, shown as a plurality of magnets 254 (also referred to as thermometer magnets), proximate the opening 252. The plurality of magnets 254 are configured to removably couple the thermometer device 200 to an attachment. For example, an attachment may include corresponding magnets that magnetically couple the attachment to the thermometer device 200. According to various embodiments, the poles of the magnets 254 may be oriented in a specific pattern to ensure proper alignment between the thermometer device 200 and the attachment. For example, if the attachment includes a window for the proximity sensor 238, the poles of the magnets 254 and the poles of the magnets in the attachment may be oriented such that the window in the attachment aligns with the proximity sensor 238 when the attachment is coupled to the thermometer device 200. In some embodiments, the thermometer device 200 may include more or fewer magnets 254 than shown in FIG. 4B, such as only one magnet.

[0063] Referring now to FIG. 5, a cross sectional view of the thermometer device 100 is shown. As shown, the thermometer device 100 includes a thermometer coupler, shown as a plurality of grooves 154 within the opening 152. The plurality of grooves 154 may be configured to receive a corresponding detent of an attachment to couple the thermometer device 100 to the attachment. According to various embodiments, the grooves 154 include a sensor configured to detect if an attachment is coupled to the thermometer device 100 and/or the type of attachment that is coupled to the thermometer device 100. For example, electrical contacts may be positioned in the grooves 154 and be electrically coupled to the circuit board 148, which may detect the attachment when the detents of the attachment contact the electrical contacts.

[0064] According to various embodiments, the thermometer device 100 may adjust the temperature output displayed based on the type of attachments coupled to the thermometer device 100. For example, the thermometer device 100 may utilize a first lookup table to determine a temperature to display when a basal attachment is used and a second lookup table to determine a temperature to display when an ear attachment is used. Further, the display may indicate which attachment is coupled to the thermometer device 100 in response to detecting the attachment.

[0065] Referring now to FIG. 6, a side view of a basal attachment 600 is shown, according to an example embodiment. The basal attachment 600 includes a basal attachment coupler that is configured to couple with a thermometer coupler of a thermometer device. The basal attachment coupler is shown in FIG. 6 as a plurality of detents 620 (e.g., ball detents, spring plungers, etc.). As shown, the basal attachment 600 extends from a basal attachment first end 602 to a basal attachment second end 604, wherein the basal attachment second end 604 is configured to be received within an opening (e.g., the opening 152, the opening 252, etc.) of a thermometer device. The basal attachment 600 includes a tip 610 proximate the basal attachment first end 602. The tip 610 may be configured to conduct heat when inserted into a subject. The temperature sensor of the thermometer device may then measure the temperature of the tip 610 and display a temperature based on the measured temperature of the tip 610.

[0066] In implementations where the basal attachment 600 is intended to be used in conjunction with a thermometer device having magnets, the basal attachment coupler may include one or more magnets (also referred to as basal attachment magnets) positioned within the basal attachment 600. The plurality of magnets may correspond with a plurality of magnets in a thermometer device (e.g., the plurality of magnets 254 shown in FIG. 4B). According to various embodiments, the poles of the magnets within the basal attachment 600 may be oriented to achieve a desired orientation of the basal attachment 600 while coupled to the thermometer device. For example, the poles of the magnets 254 in the thermometer device 200 may be oriented in a specific pattern to ensure proper alignment between the thermometer device 200 and the basal attachment 600 as is discussed further herein.

[0067] Alternatively or additionally, the basal attachment 600 may include a second temperature sensor. For example, the tip 610 may be thermally coupled to a temperature sensor (e.g., a thermocouple or thermistor) that is located on or within the basal attachment 600 such that the temperature sensor on or within the basal attachment 600 may be used to measure a temperature of the subject and communicate that temperature reading to the thermometer device that is coupled to the basal attachment 600. According to various embodiments, the detents 620 are configured to electrically couple to electrical contacts of the thermometer device 100, 200 so as to provide power to and/or receive data from the temperature sensor within the basal attachment such that the temperature sensor is able to provide temperature measurements to the thermometer device.

[0068] Referring now to FIG. 7, a side view of an ear attachment 700 is shown, according to an example embodiment. The ear attachment 700 is configured to couple with a thermometer coupler of a thermometer device via an ear attachment coupler, shown as detents 720. As shown, the ear attachment 700 extends from an ear attachment first end 702 to an ear attachment second end 704, wherein the ear attachment second end 704 is configured to be received within an opening (e.g., the opening 152, the opening 252, etc.) of a thermometer device. The ear attachment 700 includes an opening 710 proximate the ear attachment first end 702. While the ear attachment 700 is coupled to a thermometer device, the opening 710 aligns with the temperature sensor such that IR radiation can pass through the opening 710 and can be measured by the temperature sensor while the material surrounding the opening 710 blocks unwanted IR radiation from reaching the temperature sensor.

[0069] In implementations where the ear attachment 700 is intended to be used in conjunction with a thermometer device having magnets, the ear attachment coupler may include one or more magnets (also referred to as ear attachment magnets) positioned within the ear attachment 700. The plurality of magnets may correspond with a plurality of magnets in a thermometer device (e.g., the plurality of magnets 254 shown in FIG. 4B). According to various embodiments, the poles of the magnets within the ear attachment 700 may be orientated to achieve a desired orientation of the ear attachment 700 while coupled to the thermometer device. For example, the poles of the magnets 254 in the thermometer device 200 may be orientated in a specific pattern to ensure proper alignment between the thermometer device 200 and the ear attachment 700 as is discussed further herein.

[0070] Referring now to FIGS. 8 and 9, perspective views of the basal attachment 600 and thermometer device 100 are shown, according to an example embodiment. As shown, the basal attachment 600 can be coupled to the thermometer device 100 while the thermometer is in the expanded orientation (see FIG. 8) and the collapsed orientation (see FIG. 9).

[0071] Referring now to FIGS. 10-12, perspective views of the ear attachment 700 and thermometer device 100 are shown, according to an example embodiment. As shown, the ear attachment 700 can be coupled to the thermometer device 100 while the thermometer is in the expanded orientation (see FIG. 10) and the collapsed orientation (see FIGS. 11 and 12).

[0072] Referring now to FIGS. 13 and 14, cross sectional views of the basal attachment 600 being coupled to the thermometer device 100 are shown, according to an example embodiment. As shown, the detents 620 of the basal attachment 600 are received within the groove 154 in the opening 152 to couple the basal attachment 600 to the thermometer device 100. It should be appreciated that the ear attachment 700 may be coupled to the thermometer device 100 in a similar manner.

[0073] Referring now to FIGS. 15 and 16, a thermometer device 300 is shown according to an example embodiment. The thermometer device 300 may be substantially similar to the thermometer device 100, except as shown and described herein. The reference numbers of the component parts of the thermometer device 300 correspond to the reference numbers of the component parts of the thermometer device 100 with two hundred added to each reference number. For example, the thermometer device 300 includes an activation device, shown as a power button 330 corresponding to the power button 130 of the thermometer device 300. Like the thermometer device 100 the thermometer device may be configured to translate between a collapsed orientation (e.g., as shown in FIG. 16) and an extended orientation (not shown but similar to the configuration of the thermometer device 100 as shown in FIG. 1). The thermometer device 300 includes a temperature sensor 336, which may include an IR sensor configured to detect a temperature of a subject without physically contacting the subject. [0074] The thermometer device 300 includes an opening 352 through which the temperature sensor 336 may detect a temperature. The thermometer device 300 includes a funnel 351 defining the opening 352 as well as a funnel wall 353 (also referred to herein as an opening wall) shaped to receive an attachment (e.g., a basal attachment or an ear attachment as described herein. The thermometer device 300 may not include grooves 154 as included in the thermometer device 100. Instead, the attachments configured to couple to the thermometer device 300 may include surfaces with shapes complementary to the surface of the funnel wall 353, such that when an attachment is inserted into the opening 352, the attachment surface may couple to the funnel wall 353 by friction.

[0075] Alternatively or additionally, one or more magnets 363 may be used to retain the attachment to the funnel 351. The thermometer device 300 may include electrical contacts 355 that contact a corresponding contact on an attachment to detect the attachment. The electrical contacts 355 may be shaped and positioned so as to be flush with the funnel wall 353. The thermometer device 300 may determine the type of attachment coupled thereto based on detecting the attachment via the electrical contacts 355. The one or more magnets 363 may be positioned and oriented to align the electrical contacts of the attachments with the electrical contacts 355.

[0076] In some examples, heat from a user’s hand may affect the temperature measurements taken by the temperature sensor 336. The thermometer device 300 includes a heat dissipation collar 357 surrounding the temperature sensor 336. The heat dissipation collar 357 may conduct heat from a user’s hand or from various electrical components of the thermometer device (e.g., resistors, LEDs, etc.) around the temperature sensor 336, allowing the heat to dissipate away from the temperature sensor 336. This may allow the temperature sensor 336 to take more accurate temperature measurements. The heat dissipation collar 357 may also help to equalize the temperature around the temperature sensor 336, reducing temperature gradients proximate the temperature sensor 336. For example, in a thermometer device without a heat dissipation collar 357, a user’s finger may heat up an adjacent side of the temperature sensor 336, while the opposite side of the sensor may not heat up as much. Reducing the temperature difference across the temperature sensor 336 may improve the accuracy of the temperature measurements. The heat dissipation collar 337 may be made of a material with a relatively high thermal conductivity (e.g., a higher thermal conductivity than the second portion 120 of the body), such as copper or brass.

[0077] As shown, the thermometer device 300 includes a temperature sensor circuit board 359 to which the temperature sensor 336 is coupled. The temperature sensor circuit board 359 is electrically and communicatively coupled to the circuit board 348, such that the temperature measurements taken by the temperature sensor 336 can be communicated to a controller included in the circuit board 348. The controller, which may include at least one memory storing instructions and at least one processor configured to execute the instructions, may receive the temperature measurements from the temperature sensor 336, may determine a temperature detected and may cause a display screen (e.g., similar to the display screen 142) to display the determined temperature.

[0078] As shown, the thermometer device 300 includes a coupler member 361 coupled to the funnel 351. One or more fasteners 363 (e.g., screws) couple the temperature sensor circuit board 359 to the coupler member 361 and the funnel 351. The coupler member 361 may include pockets that receive and retain the magnets 363. The coupler member 361 may also have a funnel temperature sensor 365 (also referred to herein as an opening temperature sensor) coupled thereto. In some examples, the measurements of the temperature sensor 336 may be affected by the temperature of the funnel 351. For example, when the thermometer device 300 is used without an attachment, the temperature sensor 336 may detect both the body of a subject at which the thermometer device is pointed and a portion of the funnel wall 353. The temperature of the funnel wall 353 may thus affect the temperature measurements of the temperature sensor 336, which may result in an inaccurate measurement of the body temperature of the subject.

[0079] The funnel temperature sensor 365 may be configured to directly detect the temperature of the funnel 351. The measurements taken by the funnel temperature sensor 365 may be communicated to the controller of the circuit board 348, which may take into account the temperature of the funnel when determining the temperature to display. For example, when the funnel temperature sensor 365 indicates that the funnel 351 is relatively hot, the controller may determine that the temperature measurement taken by the temperature sensor 336 is higher than the actual body temperature of the subject (e.g., because the temperature of the funnel 351 is affecting the measurements of the temperature sensor 336). The controller may reduce the determined temperature of the body and cause the reduced temperature to be displayed. The funnel temperature sensor 365 may be, for example, a thermistor or thermocouple and may be partially surrounded by a foam material. The foam material may insulate the funnel temperature sensor 365 from the outside of the thermometer device 300, such that the funnel temperature sensor 365 detects only or primarily the temperature of the funnel 351.

[0080] Referring now to FIG. 17, a side view of a basal attachment 800 is shown, according to an example embodiment. The basal attachment 800 may be substantially similar to the basal attachment 600, except as shown and described herein. The reference numbers of the component parts of the basal attachment 800 correspond to the reference numbers of the component parts of the basal attachment 600 with two hundred added to each reference number. For example, the basal attachment 800 includes a tip 810 corresponding to the tip 610 of the basal attachment 600. As shown, the basal attachment 800 includes a basal temperature sensor 811 (e.g., a thermistor or thermocouple) positioned in the tip 810. The basal temperature sensor 811 is configured to detect the temperature of a cavity into which the basal attachment 800 is inserted.

[0081] The basal temperature sensor 811 may be coupled to one or more of the detents 820 by wires 813 (shown in FIGS. 19 and 20). Power may be supplied from the body of the thermometer device 300 (e.g., from a battery or external power source) to the detents 820 (and thereby to the basal temperature sensor 811) via the electrical contacts 355. The basal temperature sensor 811 may take temperature measurements and communicate the measurements to the controller of the circuit board 358 via the detents 820 and the electrical contacts 355. These measurements, either alone or in combination with measurements from the funnel temperature sensor 365 and/or the temperature sensor 336, may be used by the controller to determine the body temperature of the subject. The basal attachment 800 may include magnets positioned adjacent the basal attachment second end 804, which may magnetically couple the basal attachment 800 to the magnets 363 in the body of the thermometer device 300.

[0082] Referring now to FIG. 18, a side view of an ear attachment 900 is shown, according to an example embodiment. The ear attachment 900 may be substantially similar to the ear attachment 700, except as shown and described herein. The reference numbers of the component parts of the ear attachment 900 correspond to the reference numbers of the component parts of the ear attachment 700 with two hundred added to each reference number. For example, the ear attachment 900 includes an opening 910 corresponding the opening 710 of the ear attachment 700. As shown, the ear attachment 900 includes an ear temperature sensor 911 (e.g., an IR sensor) positioned adjacent the ear attachment first end 902. The ear temperature sensor 911 may function substantially similarly to the temperature sensor 336. For example, IR radiation may pass through the opening 910 in the ear attachment 900 and be detected by the ear temperature sensor 911 to measure the temperature of an ear into which the ear attachment 900 is inserted.

[0083] The ear temperature sensor 911 may be electrically and communicatively coupled to the detents 920, for example, via wires or a circuit board, and the detents 920 may couple to the electrical contacts 355. Power may be supplied from the body of the thermometer device 300 (e.g., from a battery or external power source) to the detents 920 (and thereby to the ear temperature sensor 911) via the electrical contacts 355. The ear temperature sensor 911 may take temperature measurements and communicate the measurements to the controller of the circuit board 358 via the detents 920 and the electrical contacts 355. These measurements, either alone or in combination with measurements from the funnel temperature sensor 365 and/or the temperature sensor 336, may be used by the controller to determine the body temperature of the subject. The ear attachment 900 may include magnets positioned adjacent the ear attachment second end 904, which may magnetically couple the ear attachment 900 to the magnets 363 in the body of the thermometer device 300.

[0084] Referring now to FIGS. 19 and 20, cross sectional views of the basal attachment 800 being coupled to the thermometer device 300 are shown, according to an example embodiment. As shown, the basal attachment second end 804 is received within the opening 352 of the body of the thermometer device 300. As discussed above, the opening 352 may not include grooves into which the detents 820 may extend. Instead, the electrical contacts 354 may be flush with the funnel wall 353, and the detents 820 may contact the electrical contacts 354 to form an electrical connection but may not mechanically couple the basal attachment 800 to the thermometer device 300. The basal attachment 800 may instead be magnetically coupled to the thermometer device 300 by the magnets 363. For example, the basal attachment 800 may be made from or include magnetically permeable materials that are attracted to the magnets 363, or the basal attachment may itself have magnets that magnetically couple to the magnets 363. Alternatively or additionally, friction between the basal attachment 800 and the funnel wall 353 may hold the basal attachment 800 in place within the opening 352. It should be appreciated that the ear attachment 900 may be coupled to the thermometer device 300 in a similar manner.

[0085] Referring now to FIG. 21, a schematic view of a temperature measurement system 1000 is shown according to an example embodiment. As shown, the temperature measurement system 1000 includes the thermometer device 300 and at least one of the basal attachment 800 or the ear attachment 900. In other examples, the temperature measurement system 1000 may include the thermometer device 100 or the thermometer device 200, and/or may include the basal attachment 600 or the ear attachment 700 but may otherwise be substantially similar. As shown, the thermometer device 300 includes a display screen 342, a temperature sensor 336, a funnel temperature sensor 365, a proximity sensor 338, and a circuit board 348, as discussed above. The thermometer device may include additional components not shown in FIG. 21 (e.g., a power button 330, a light 346, etc.) The circuit board 348 includes a controller 371 that is communicatively coupled to the display screen 342, the temperature sensor 336, the funnel temperature sensor 365, and the proximity sensor 338.

[0086] The controller 371 includes at least one memory 373 and at least one processor 375. The at least one memory 373 stores instructions that, when executed by the at least one processor 375, cause the at least one processor 375 to execute the functions of the thermometer device 300. For example, when no attachment is coupled to the thermometer device 300, the controller 371 may be configured to receive temperature measurements from the temperature sensor 336 and the funnel temperature sensor 365. The at least one processor 375 may determine, based on the received temperature measurements and the instructions stored in the at least one memory 373, a body temperature of a subject at which the thermometer device 300 is pointed.

[0087] For example, the controller 371 may receive a first measurement from the temperature sensor 336, a second measurement from the funnel temperature sensor 365, and a distance measurement from the proximity sensor 338. The at least one processor 375 may adjust the first temperature measurement based on the second temperature measurement and/or the distance measurement to determine the body temperature of the subject. Thus, the body temperature of the subject may be determined based on both the first temperature measurement and the second temperature measurement and may also be based on the detected distance to the subject. For example, an increase in the distance measurement from the proximity sensor 338 may cause the first temperature measurement from the temperature sensor 336 to be lower than the real body temperature of the subject. An increase in the temperature of the funnel 351, as detected by the funnel proximity sensor 365, may cause the first temperature measurement from the temperature sensor 336 to be higher than the real body temperature of the subject.

[0088] The processor 375 may thus correct for both the distance from the subject and the temperature of the funnel 351. The at least one memory 373 may include lookup tables and/or formulas for determining the body temperature based on the measurements from the various sensors 336, 338, 365. Upon determining the body temperature of the subject, the controller 371 may send a signal to the display screen 342 causing the determined body temperature to be displayed.

[0089] The controller 371 may be communicatively coupled to the electrical contacts 355, which may releasably couple to the electrical contacts of an attachment, such as the detents 820 of the basal attachment 800 or the detents 920 of the ear attachment 900. The controller 371 may determine a type of the attachment based on a signal from the electrical contacts 355. For example, when the basal attachment 800 is coupled to the thermometer device 300, the controller 371 may receive a first signal, and when the ear attachment 900 is coupled to the thermometer device 300, the controller 371 may receive a different signal. The detents 820, 920 may be respectively communicatively coupled to the basal temperature sensor 811 and the ear temperature sensor 911, such that the controller may receive temperature measurements from the basal temperature sensor 811 or the ear temperature sensor 911 when the respective attachment 800, 900 is coupled to the thermometer device 300.

[0090] In some examples, the controller 371 may determine the body temperature of the subject based only on the measurements from the basal temperature sensor 811 or the ear temperature sensor 911. In other examples, the controller 371 may determine the body temperature of the subject based on the measurement from the basal temperature sensor 811 or the ear temperature sensor 911 in combination with measurements from the other sensors 336, 338, 365. As discussed above, upon determining the body temperature of the subject, the controller 371 may send a signal to the display screen 342 causing the determined body temperature to be displayed [0091] Because the thermometer devices 100, 200, 300 can be used with multiple different attachments, or without any attachments, a subject’s temperature may be measured in a number of different locations, each of which may have one or more benefits. For example, measuring the subject’s temperature without contacting the subject may be faster and/or more sanitary than other methods. However, using a basal attachment or an ear attachment may provide more accurate results in certain situations.
