[0013] The following disclosure relates to modular sensing components used as part of electronic devices. Modular sensing components can receive various types of user input. Exemplary user inputs include touch input, fingerprint input, panning input, audio input, biometric input, etc. Input received using modular sensing components can be used to control the graphical output of the display of an electronic device. Modular sensing components can be configured as, for example, a power button, keyboard keys, control buttons (e.g., volume control), a home button, a crown, etc.

[0014] Combining multiple components in a modular sensing assembly offers advantages over traditional input mechanisms. These advantages include reduced component redundancy and manufacturing complexity. For example, a modular sensing assembly may include a single sealing member that provides a seal around all components of the modular sensing assembly and / or between the modular sensing assembly and the device housing. This reduces the total number of components required to assemble the electronics, which can lower manufacturing complexity and cost, and minimize device size. As another example, multiple components of a modular sensing assembly can be operatively coupled to a processing unit using one or more common connectors and / or common channels into the internal volume of the device.

[0015] Modular sensing components may be at least partially located within the housing of an electronic device. Exemplary inputs received by the modular sensing components may include touch input, panning input, fingerprint input, audio input, electrocardiogram signals, etc. The modular sensing components may provide one or more outputs. Exemplary outputs provided by the modular sensing components include audio output, tactile output, visual output, etc.

[0016] As discussed in more detail below, modular sensing assemblies may include multiple sensors, sub-assemblies, and / or other components located within the assembly housing. Combining multiple components in a modular sensing assembly offers advantages over traditional input mechanisms. These advantages include reduced device component redundancy and manufacturing complexity. For example, a modular sensing assembly may include a single sealing member that provides a seal around all components of the modular sensing assembly and / or between the modular sensing assembly and the device housing. As another example, multiple components of a modular sensing assembly may be operatively coupled to a processing unit using one or more common connectors and / or common channels into the internal volume of the electronic device.

[0017] The modular sensing assembly described herein may include a sealing member that prevents contaminants from entering the internal volume and / or housing of an electronic device. As used herein, "contaminant" can be used to refer to foreign matter not intended to be present in the internal volume of an electronic device. Exemplary contaminants include liquids such as water, and solid substances such as lint, dust, and food particles. In one embodiment, the sealing member is positioned between one or more components of the modular sensing assembly and one or more surfaces of the housing of the electronic device.

[0018] As used herein, the term "attachment" can be used to refer to the physical fixation, fastening, and / or holding of two or more elements, structures, objects, components, parts, etc., together with each other. As used herein, the term "coupled" can be used to refer to the physical attachment, operation, communication, electrical connection, and / or other interaction between two or more elements, structures, objects, components, parts, etc., together with each other. Therefore, when attached elements are connected to each other, the orientation does not need to be reversed. As used herein, "operably coupled" or "electrically coupled" can be used to refer to two or more devices coupled in any suitable manner (including wired, wireless, or some combination thereof) for operation and / or communication.

[0019] The following text is for reference only. Figures 1A to 4 These and other embodiments are discussed. However, those skilled in the art will readily understand that the detailed descriptions given herein with respect to the accompanying drawings are for illustrative purposes only and should not be construed as limiting.

[0020] Figure 1A A block diagram of an exemplary electronic device 100 that can incorporate a modular sensing component 110 is shown. The electronic device 100 may include a display 122, one or more input devices 124, one or more output devices 126, and the modular sensing component 110. Each component of the electronic device 100 may be operatively coupled to a processing unit 128. The electronic device 100 may include a housing 120. The components of the electronic device 100 may be at least partially located within an internal volume 121 of the housing 120.

[0021] Modular sensing component 110 may be at least partially located within housing 120 of electronic device 100 and may be configured to receive input and / or provide output. Exemplary inputs received by modular sensing component 110 may include touch input, panning input, fingerprint input, audio input, electrocardiogram signal, etc. Exemplary outputs provided by modular sensing component 110 may include audio output, tactile output, visual output, etc. Modular sensing component 110 may be operatively coupled to processing unit 128, for example, via connector 130a.

[0022] As discussed in more detail below, the modular sensing assembly 110 may include multiple sensors, sub-assemblies, and / or other components located within the assembly housing. Combining multiple components in the modular sensing assembly 110 provides advantages over conventional input mechanisms. These advantages include reduced device component redundancy and manufacturing complexity. For example, the modular sensing assembly 110 may include a single sealing member that provides a seal around all components of the modular sensing assembly 110 and / or between the modular sensing assembly 110 and the housing 120. As another example, multiple components of the modular sensing assembly 110 may be operatively coupled to a processing unit using one or more common connectors and / or common channels into the internal volume 121.

[0023] In various embodiments, the display 122 may be at least partially located within the internal volume 121 of the housing 120. The display 122 provides graphical output, for example, associated with the operating system, user interface, and / or applications of the electronic device 100. In one embodiment, the display 122 includes one or more sensors and is configured as a touch-sensitive display (e.g., single-touch, multi-touch) and / or force-sensitive display to receive input from a user. The display 122 is operatively coupled to the processing unit 128 of the electronic device 100, for example, via a connector 130b. In some cases, the graphical output of the display 122 is visible along at least a portion of the outer surface of the electronic device 100.

[0024] In various embodiments, the graphic output of display 122 is responsive to inputs provided at the display, one or more input devices 124, and / or one or more modular sensing components 110. For example, processing unit 128 may be configured to modify the graphic output of display 122 in response to determining an electrocardiogram, receiving rotation input, receiving translation input, receiving touch input, receiving fingerprint input, receiving audio input, etc. In some cases, the tactile output provided by modular sensing components 110 corresponds to the graphic output of display 122. In some cases, modular sensing components 110 may generate tactile output that is coordinated with changes in the graphic output of display 122. For example, tactile output may be generated simultaneously with or nearly simultaneously with changes in the graphic output of display 122. In some cases, the timing of generating tactile output overlaps with the timing of changes in the graphic output of display 122.

[0025] The display 122 can be implemented using any suitable technology, including but not limited to liquid crystal display (LCD) technology, light-emitting diode (LED) technology, organic light-emitting display (OLED) technology, organic electroluminescent (OEL) technology, or another type of display technology. In some cases, the display 122 is positioned under a cover and can be seen through the cover.

[0026] In a general sense, input device 124 can detect various types of input, and output device 126 can provide various types of output. Modular sensing component 110 can be an example of input device 124. Similarly, modular sensing component 110 can be an example of output device 126. Processing unit 128 can be operatively coupled to input device 124 and output device 126, for example, via connectors 130c and 130d, respectively. Processing unit 128 can receive input signals from these input devices in response to input detected by input device 124. Processing unit 128 can interpret the input signals received from one or more input devices 124 and transmit output signals to one or more output devices 126. The output signals can cause output device 126 to provide one or more outputs. Inputs detected at one or more input devices in input device 124 can be used to control one or more functions of electronic device 100.

[0027] In some cases, one or more output devices 126 may be configured to provide output dependent on or manipulated in response to input detected by one or more input devices 124. The output provided by one or more output devices 126 may also respond to or be initiated by a program or application executed by the processing unit 128 and / or associated accompanying devices. The following is relative to... Figure 4 Examples of suitable processing units, input devices, output devices, and displays are discussed in more detail.

[0028] Figure 1B It shows Figure 1A A block diagram of an exemplary modular sensing component 110 is provided. The modular sensing component 110 may include a touch sensor 140, a fingerprint sensor 142, a translation sensor 144, an audio sensor 146, an electrocardiogram (ECG) electrode 148, and one or more output devices 149. As described above, the components of the modular sensing component 110 may be at least partially located within the component housing 111.

[0029] Touch sensor 140 can be any suitable device for detecting touch input to modular sensing component 110. As used herein, “touch input” can refer to any contact or proximity contact between a user (e.g., a user’s finger) or another object and one or more input surfaces of modular sensing component 110. Touch input can be tapping, pressing, gestures (e.g., swiping), etc.

[0030] Touch sensor 140 can be implemented as a capacitive sensor, resistive sensor, contact sensor, magnetic sensor, optical sensor, ultrasonic sensor, etc. Touch sensor 140 can provide a signal in response to touch input, which can indicate that the touch input occurred, the type of input (e.g., tap, press, gesture, etc.), the location of the input, and / or the magnitude of the input (e.g., force measurement). In some cases, modular sensing assembly 110 includes a cover defining an input surface on the outer surface of the modular sensing assembly, and touch sensor 140 can be positioned under the cover of modular sensing assembly 110 to detect touch input on or near the input surface.

[0031] The output provided by the electronic device 100 may be in response to touch input detected by the touch sensor 140. For example, the graphics output provided by the display 122 and / or the audio output provided by the audio output device may be in response to touch input detected by the touch sensor 140.

[0032] The fingerprint sensor 142 can be any suitable device for detecting fingerprint input at the modular sensing component 110. As used herein, "fingerprint input" can refer to any representation of a user's fingerprint, including fingerprint images, fingerprint maps, etc. The processing unit 128 can use the fingerprint input to perform authentication operations at the electronic device 100.

[0033] The fingerprint sensor 142 can be implemented as a capacitive sensor, resistive sensor, contact sensor, magnetic sensor, optical sensor, ultrasonic sensor, camera, etc. The fingerprint sensor 142 can provide a signal in response to fingerprint input, which can contain information related to the fingerprint input. In some cases, the fingerprint sensor 142 can be positioned under the cover of the modular sensing assembly 110 to detect fingerprint input on or near the input surface. The fingerprint sensor 142 can be a region sensor, meaning that the fingerprint sensor 142 does not require a swipe of the user's finger to capture enough fingerprints to uniquely identify the user. The fingerprint sensor 142 can have sufficiently high resolution so that it can be used to uniquely identify an individual using a relatively small segment of the user's fingerprint. In some cases, the width of the input surface is between 2 mm and 5 mm, and the fingerprint sensor 142 can still uniquely identify an individual using the fingerprint captured at the input surface. In some cases, the fingerprint sensor 142 can be a swipe-type fingerprint sensor.

[0034] The output provided by the electronic device 100 may be in response to fingerprint input detected by the fingerprint sensor 142. For example, the graphic output provided by the display 122 and / or the audio output provided by the audio output device may be in response to fingerprint input detected by the fingerprint sensor 142.

[0035] Translation sensor 144 can be any suitable device for detecting translation input at modular sensing assembly 110. As used herein, "translation input" can refer to an input to modular sensing assembly 110 that causes the modular sensing assembly or a portion thereof to move or translate. Translation can include inward and outward translation, lateral translation, and other movements of one or more parts of modular sensing assembly 110 (e.g., a cover). For example, the cover of modular sensing assembly 110 can be pressed down in response to a user pressing on an input surface. Modular sensing assembly 110 or a portion thereof can translate inward in response to a user pressing on an input surface. Translation sensor 144 can detect this as a translation input.

[0036] Translation sensor 144 can be implemented as a physical switch (e.g., a tactile dome switch), a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, an optical sensor, an ultrasonic sensor, etc. Translation sensor 144 can provide a signal in response to a translation input, indicating the occurrence of the translation input, the location of the input, and / or the measurement of the input (e.g., force measurement). In some cases, translation sensor 144 can be positioned under the cover of modular sensing assembly 110 to detect translation input on or near the input surface.

[0037] The output provided by the electronic device 100 may be in response to a translation input detected by the translation sensor 144. For example, the graphics output provided by the display 122 and / or the audio output provided by the audio output device may be in response to a translation input detected by the translation sensor 144.

[0038] The audio sensor 146 can be any suitable device for detecting audio input at the modular sensing component 110. As used herein, “audio input” can refer to any detected or measured sound. For example, the audio sensor 146 can detect sound from the environment surrounding the electronic device 100 for use in voice commands and other device control, recording, noise level detection, voice communication (e.g., telephone calls), etc.

[0039] The audio sensor 146 can be implemented as a microphone or any device used to measure or detect audio signals. The audio sensor 146 can provide a signal corresponding to the audio input to the processing unit 128. In some cases, the audio sensor 146 can be positioned under the cover of the modular sensing assembly 110 to detect audio input through the cover and / or through an opening in the cover.

[0040] The output provided by the electronic device 100 may be in response to an audio input detected using the audio sensor 146. For example, the graphic output provided by the display 122 and / or the audio output provided by the audio output device may be in response to an audio input detected using the audio sensor 146.

[0041] ECG electrodes 148 may be disposed on one or more outer surfaces of the modular sensing assembly 110. A processing unit 128 or other sensing circuitry of the electronic device 100 may monitor the voltage or signal received on the ECG electrodes 148. The electronic device 100 may include one or more additional electrodes positioned on the outer surface of the electronic device, which may be used to provide electrocardiogram functionality to the electronic device.

[0042] In some embodiments, ECG electrode 148 may be disposed (e.g., PVD deposited) on the outer surface of modular sensing assembly 110. ECG electrode 148 may be positioned on the outer surface of a cover of modular sensing assembly 110. The surface may be any transparent, translucent, semi-translucent, or opaque surface made of amorphous solid, glass, crystalline or crystalline material (e.g., sapphire or zirconium oxide), plastic, etc. ECG electrode 148 may be positioned along a portion of the periphery of the cover of modular sensing assembly (e.g., a cover forming an input surface). The periphery of the cover may be curved, and ECG electrode 148 may conform to the curvature of the periphery of the cover. As an example, ECG electrode 148 may define a 180-degree curve along the portion of the periphery of the cover in which it is placed. ECG electrode 148 may at least partially surround a region of the cover that does not contain an ECG electrode. ECG electrode 148 may have a C or U shape and may at least partially surround a portion of the cover where no ECG electrode is present. ECG electrode 148 may extend from the outer surface of the cover around the edge of the cover to a connector beneath the cover (e.g., a connector coupled to the inner surface of the cover). This can improve the ability of the modular sensing assembly 110 to remove contaminants by eliminating the need to pass the connector through a hole in the cover of the electronic device 100 or another component.

[0043] The output provided by the electronic device 100 may be in response to a signal received on the ECG electrode 148. For example, graphic output provided by the display 122 and / or audio output provided by the audio output device may be in response to a signal received on the ECG electrode 148.

[0044] Output device 149 may provide output at modular sensing component 110. Output device 149 may include tactile output device (e.g., tactile actuator) for providing tactile output, audio output device (e.g., speaker) for providing audio output, and / or visual output device (e.g., lamp) for providing visual output.

[0045] As used herein, the terms "haptic output" and "tactile output" can refer to outputs generated by an electronic device that can be perceived by a user's touch. Examples of haptic outputs include vibrations, deflections, and other movements of a device housing, cover, or input device or another device component forming an input surface of the electronic device. In some cases, haptic outputs can provide feedback about input received at a specific location on the electronic device. For example, a haptic output can be provided at modular sensing assembly 110 to provide feedback related to input provided at the modular sensing assembly. In other cases, haptic outputs can provide other types of feedback or information to the user, such as alarms received at the electronic device.

[0046] Modular sensing component 110 may include a ratio relative to Figure 1BThe components shown and described may have more or fewer components. In some cases, a single device or sub-component can provide the functionality described relative to the multiple components mentioned above. For example, a single audio device may be able to detect and provide audio input. As another example, a single sensing device may be able to detect touch input and fingerprint input. Similarly, a single sensing device may be able to detect touch input and translation input.

[0047] Figures 2A to 2C An exemplary electronic watch 200 is shown, including a modular sensing component 210. The electronic watch 200 may have a sensor relative to... Figure 1A and Figure 1B The electronic devices discussed 100 have the same or similar functions and structures. Other devices that may contain the modular sensing components described herein include other wearable electronic devices, other timing devices, other health monitoring or fitness devices, other portable computing devices, mobile phones (including smartphones), tablet computing devices, digital media players, virtual reality devices, audio devices (including earbuds and headphones), etc.

[0048] like Figure 2A As shown, the electronic watch 200 may include a watch body 220 and a watch strap 224. The watch body 220 may include a case 222. The case 222 may contain one or more components of the electronic watch 200 and may define at least a portion of the outer surface of the electronic watch.

[0049] Modular sensing component 210 may be positioned in recess 228 along sidewall 222a of housing 222. Modular sensing component 210 may include cover 212 that defines at least a portion of an input surface 214 forming the outer surface of electronic watch 200. Input surface 214 may include multiple areas for detecting different types of input. For example, such as... Figure 2A As shown, the input surface 214 may include an ECG region 214a capable of detecting ECG signals, a fingerprint sensing region 214b capable of detecting fingerprint input, and an audio sensing region 214c including an opening 216 through which audio signals can be detected. In some cases, the ECG region 214a, the fingerprint sensing region 214b, and / or the audio sensing region 214c may also be a touch sensing region in which touch input can be received.

[0050] Modular sensing component 210 may be able to receive translation input. For example, a user may press inward on input surface 214 to provide translation input to modular sensing component 210. Cover 212 may translate inward in response to translation input. In some cases, cover 212 may deflect or bend in response to translation input. In some cases, cover 212 may not translate, deflect, or bend in response to translation input. Modular sensing component 210 may include one or more translation sensors to detect translation input.

[0051] ECG region 214a may include ECG electrodes 218 disposed on the outer surface of cover 212. ECG electrodes 218 may be configured to detect ECG signals, for example, from a user's finger placed on the ECG electrodes. The ECG signals can be used to provide electrocardiogram (ECG) functionality for the electronic watch 200. Figure 2A As shown, the ECG electrode 218 can be positioned along a portion of the periphery of the cover 212. The periphery of the cover 212 can be curved, and the ECG electrode 218 can conform to the curvature of the periphery of the cover 212. As an example, the ECG electrode 218 can define a 180-degree curve along the portion of the periphery of the cover 212 in which it is placed, such as... Figure 2A As shown. The ECG electrode 218 may at least partially surround the area of ​​the outer cover excluding the ECG electrode. For example, as Figure 2A As shown, the ECG electrode 218 has a C or U shape and at least partially surrounds a portion of the ECG region 214a where no ECG electrode is present. As discussed in more detail below, the ECG electrode 218 can extend from the outer surface of the cover around the edge of the cover 212 to a connector beneath the cover (e.g., a connector coupled to the inner surface of the cover). This improves the ability of the modular sensing assembly 210 to remove contaminants by eliminating the need for a hole in the cover 212 of the electronic watch 200 or another component.

[0052] ECG electrode 218 can be formed of any suitable material or combination of materials for receiving ECG signals, including metals and other conductive materials. Cover 212 or one or more portions thereof can be formed of a non-conductive material to electrically isolate ECG electrode 218 from other components of the electronic watch 200 to reduce interference and signal noise introduced into the ECG signal. In some cases, modular sensing assembly 210 may include an isolation component disposed between ECG electrode 218 and one or more additional components of the modular sensing assembly to reduce interference and signal noise introduced into the ECG signal.

[0053] Cover 212 can be configured to allow input to be detected by a component of modular sensing assembly 210 positioned beneath the cover. Cover 212 may be formed of or include a non-conductive and / or dielectric material that allows sensing signals (such as capacitive signals, ultrasonic signals, etc.) to pass through the cover. As an example, cover 212 may be formed of sapphire. Cover 212 may be formed of a transparent or translucent material to allow optical sensing signals to pass through the cover. In some cases, structural features of cover 212 allow signals to pass through the cover. For example, the cover may include an opening that allows sensing signals (e.g., optical signals) to pass through the cover.

[0054] In some cases, the electronic watch 200 may include a display cover 226 that faces away from the user's skin when the watch 200 is worn. In some cases, the display cover 226 is mounted to or coupled to a housing 222. The display cover 226 may be positioned over a display (e.g., a display mounted within the housing 222) Figure 1A The display cover 226 is placed above and protects the display 122. The user can see the display through the display cover 226. In some cases, the display cover 226 may be part of a display stack that may include touch-sensing or force-sensing capabilities. The display may be configured to depict the graphical output of the electronic watch 200, and the user may interact with the graphical output (e.g., using a finger, stylus, or other pointer). As an example, the user may select (or otherwise interact with) graphics, icons, etc., presented on the display by touching or pressing (e.g., providing touch input) a graphical location on the display. In some cases, the tactile output provided by the haptic device corresponds to the graphical output of the display and / or input received via the display.

[0055] As used herein, the term "monitor cover" can be used to refer to any transparent, translucent, or semi-transparent surface made of glass, crystalline materials (such as sapphire or zirconium oxide), plastic, etc. Therefore, it should be understood that the term "monitor cover" as used herein includes both amorphous solids and crystalline solids. In some examples, the monitor cover 226 may be a sapphire cover. The monitor cover 226 may also be formed of glass, plastic, or other materials.

[0056] The watch strap 224 can be used to attach the electronic watch 200 to a user, another device, a retaining mechanism, etc. The housing 222 may include structures for attaching the watch strap 224 to the watch body 220. In some cases, these structures may include elongated recesses or openings through which the ends of the watch strap 224 can be inserted and attached to the watch body 220. In other cases (not shown), the structures may include recesses (e.g., pits or depressions) in the housing 222 that receive the end of a spring pin that attaches to or passes through the end of the watch strap to attach the strap to the watch body.

[0057] Figure 2B A partial exploded view of an exemplary electronic watch 200 is shown. Figure 2B Exemplary components of the modular sensing assembly 210 and a cross-sectional portion of the housing 222 are shown. The modular sensing assembly 210 may include a cover assembly 250, a decorative member 260, a sensing sub-assembly 270, a button sub-assembly 280, translation sensors 292a, 292b, and a retaining bracket 294. The components of the modular sensing assembly 210 may be coupled together and / or coupled to the housing 222 using one or more fasteners (e.g., fasteners 296a, 296b).

[0058] Modular sensing component 210 can be disposed in the recess along the side wall 222a of housing 222, as shown below relative to Figure 2C A more detailed description follows. Sidewall 222a may define one or more channels 290a, 290b that extend through the sidewall and into the internal volume of the electronic watch 200. Channels 290a, 290b may facilitate the attachment of the modular sensing assembly 210 to the housing 222, as described below relative to... Figure 2C For more detailed description. Additionally, channels 290a and 290b can facilitate signal transmission from the modular sensing component to the internal volume of the electronic watch 200 (e.g., using a connector that operatively couples components of the modular sensing component 210 to the processing unit or other circuitry of the electronic watch 200).

[0059] like Figure 2B As shown, the cover 212 of the modular sensing assembly 210 may be part of a cover assembly including a membrane 256, an ECG electrode 218, and an ECG connector 258. The ECG electrode 218 may extend from the outer surface of the cover 212 around the edge of the cover to the connector 258 beneath the cover. The connector 258 may be coupled to the inner surface of the cover 212 and may extend through channels 290a, 290b into the internal volume of the electronic watch 200 (e.g., to the processing unit or other circuitry of the electronic watch 200). This provides an unobstructed signal path for ECG signals from the ECG electrode 218 to the processing unit while electrically isolating the signals from the housing and the touch sensor. The ECG electrode 218 and the associated circuitry may be shielded to operate at a frequency different from that of the touch sensor 272 and / or other components of the modular sensing assembly 210, or otherwise configured to reduce parasitic effects with the touch sensor 272 and / or other components of the modular sensing assembly 210.

[0060] The sensing sub-assembly 270 may be positioned below the cover 212 and may include a touch sensor 272 and an audio sensor 274. The touch sensor 272 can detect touch input on the input surface 214 of the cover 212. (As described above relative to...) Figure 1BThe touch sensor 272 discussed can be implemented as a capacitive sensor, resistive sensor, contact sensor, magnetic sensor, optical sensor, ultrasonic sensor, etc. In some cases, the touch sensor 272 is also a fingerprint sensor for detecting fingerprint input on the input surface 214. For example, the touch sensor 272 can be a capacitive sensor configured to detect both touch input and fingerprint input on the input surface. The fingerprint sensor can be implemented as a capacitive sensor, resistive sensor, contact sensor, magnetic sensor, optical sensor, ultrasonic sensor, camera, etc. In some cases, the modular sensing assembly 210 may include a touch sensor and a fingerprint sensor as separate components.

[0061] An audio sensor 274 may be positioned below an opening 216 in the cover 212 and may be configured to detect audio input. A membrane 256 may be positioned below an opening 216 in the cover 212 to prevent contaminants from entering the modular button assembly and / or the internal volume of the electronic watch 200 via the opening 216. The membrane may at least partially transmit sound waves, allowing the audio sensor 274 to detect audio input. The membrane 256 may be formed of any suitable material that at least partially transmits sound waves and forms a barrier to exclude contaminants.

[0062] The sensing sub-assembly 270 may also include one or more connectors 276 that operatively couple the touch sensor 272 and the audio sensor 274 to the processing unit or other circuitry of the electronic watch 200. The connectors 276 may extend through channels 290a, 290b into the internal volume of the electronic watch 200.

[0063] Decorative member 260 may extend at least partially around the periphery of cover 212, and may at least partially surround cover 212, touch sensor 272, and audio sensor 274. As discussed in more detail below, decorative member 260 may form part of the component housing of the modular sensing assembly.

[0064] The button subassembly 280 may include a sealing member 282, a button retainer 284, and a button member 288. The button member 288 may be positioned within an opening formed by the sealing member 282 and / or the button retainer 284. The button retainer 284 may at least partially surround the button member 288, and the sealing member 282 may extend around the button retainer 284. As shown below relative to... Figure 2C In more detail, the button component 288 can transmit the force applied to the cover 212 to the translation sensors 292a, 292b to identify translation input.

[0065] The sealing member 282 may be a compressible gasket that forms a seal between the housing 222 and the modular sensing assembly 210. For example, such as Figure 2CAs shown, the sealing member 282 can be positioned along the inner surface of the recess 228. The sealing member 282 can extend into the internal volume around one or more channels 290a, 290b to prevent contaminants from entering the internal volume via the channels. The sealing member 282 can have a shape that allows it to compress or otherwise deform in response to translation of the cover 212, the decorative member 260, or other components of the modular sensing assembly 210. In some cases, the sealing member 282 is co-molded with the button holder 284 to simplify the assembly process of the modular sensing assembly 210.

[0066] Translation sensors 292a and 292b can be configured as any suitable device for detecting translation input at the modular sensing assembly 210. Each translation sensor 292a and 292b can be implemented as a physical switch (e.g., a tactile dome switch), a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, an optical sensor, an ultrasonic sensor, etc. Translation sensors 292a and 292b can provide a signal in response to a translation input, which can indicate the occurrence of the translation input, the location of the input, and / or the measurement of the input (e.g., force measurement).

[0067] The retaining bracket 294 can be positioned along the inner surface of the sidewall 222a. The retaining bracket 294, together with fasteners 296a, 296b, can be used to couple components of the modular sensing assembly 210 together. The button retainer 284 may include a coupling mechanism that allows the fasteners to couple the button subassembly 280 to the retaining bracket 294. For example, the button retainer 284 may include female threaded connectors 286a, 286b configured to engage with the threaded fasteners 296a, 296b.

[0068] Retaining bracket 294 and fasteners 296a, 296b can be used to secure the modular sensing assembly 210 to the housing 222. Coupling the retaining bracket 294 to the button retainer 284 can secure the modular sensing assembly 210 to the housing 222.

[0069] In some cases, the modular sensing assembly 210 may include a housing formed of one or more components. The housing may at least partially surround and / or enclose the various components of the modular sensing assembly 210, and allow the modular sensing assembly 210 to reduce the number of necessary sealing members. For example, components of a sensing subassembly may be at least partially surrounded by the housing. The housing may be formed from one or more of a cover 212, a decorative member 260, a sealing member 282, a button retainer 284, and a retaining bracket 294.

[0070] Figure 2C The section cut along line A-–A is shown. Figure 2AA cross-sectional view of an exemplary electronic watch 200. As described above, the modular sensing component 210 may be disposed in the recess 228 along the sidewall 222a of the housing 222.

[0071] Modular sensing component 210 can receive translation input that causes cover 212 to translate or otherwise move. (Go to...) Figure 2C A translation input applied to input surface 214 can cause cover 212 to translate downward toward translation sensors 292a, 292b. Button member 288 can be positioned between cover 212 and translation sensors 292a, 292b, and can be configured to translate in response to a translation input on the input surface that causes cover 212 to translate. Button member 288 can transmit the force applied to cover 212 to translation sensors 292a, 292b to recognize the translation input.

[0072] Translation of the button component 288 can actuate one or both of the translation sensors 292a and 292b. In some cases, the button component 288 can move in a rocking motion to press one of the translation sensors 292a and 292b based on the position of the translation input. For example, a translation input on a first region of the cover 212 (e.g., the cover relative to...) Figure 2C The left side of the button component can be pressed down, thereby actuating the translation sensor 292a. Similarly, the translation input on the second region of the cover 212 (e.g., the cover relative to the left side) can also be pressed down, thereby actuating the translation sensor 292a. Figure 2C The right side of the button component can press down the second end (e.g., the right end), thereby actuating the translation sensor 292b. The button component 288 can be positioned along a portion 222b of the housing or another part of the electronic watch 200 to facilitate the rocking motion of the button component.

[0073] Channels 290a and 290b facilitate attachment of the modular sensing assembly 210 to the housing 222. For example, a retaining bracket 294 may be positioned along the inner surface of the sidewall 222a, and fasteners 296a and 296b may pass through channels 290a and 290b and couple other components of the modular sensing assembly 210 to the retaining bracket 294. Coupling components of the modular sensing assembly 210 to the retaining bracket 294 secures the modular sensing assembly 210 to the housing 222.

[0074] Figures 3A to 3C An exemplary electronic watch 300 including a modular sensing component 310 is shown. The exemplary electronic watch 300 may be similar to other electronic devices discussed herein (e.g., electronic devices 100, 200) and may include similar structure and / or functionality. Figure 3AAs shown, the electronic watch 300 may include a modular sensing assembly 310 positioned in a recess 328a along a sidewall 322a of the housing 322. The modular sensing assembly 310 may include a cover 312 that defines at least a portion of an input surface 314 forming the outer surface of the electronic watch 300. The cover 316 may include an opening, for example, for detecting audio input.

[0075] The electronic watch 300 may include at least one input or selection device operable by a user of the electronic watch, such as a crown, scroll wheel, knob, dial, button, etc. The electronic watch 300 may include a crown 318 positioned along a sidewall 322a. The crown 318 may be configured to receive rotation input and / or translation input. The graphic output of the display of the electronic watch 300 may respond to input received at the crown 318 and / or the modular sensing component 310.

[0078] The button component 388 can be movably coupled to the housing 322, such that the button component 388 can translate in response to a translation input to the cover 312. The button component can be aligned with a channel 390c in the sidewall 322a, which is aligned with a translation sensor 392. When the button component 388 translates in response to the translation input, it can actuate the translation sensor 392. In some cases, components of the modular sensing assembly 310 do not move in response to the translation input, and the translation sensor 392 detects a force applied to the cover 312.

[0079] Figure 3C The section cut along the B-–B line is shown. Figure 3A A cross-sectional view of an exemplary electronic watch 300. As described above, the modular sensing component 310 may be disposed in the recess 328 along the sidewall 322a of the housing 322.

The crown body 318a may be attached to or coupled to the shaft and may be accessible to a user outside the housing 322.

[0082] The crown body 318a may be user-rotatable and user-operable (e.g., rotated, pressed) to rotate or translate the shaft 318b. The shaft 318b may be mechanically, electrically, magnetically, and / or optically coupled to components within the housing 322. User manipulation of the crown body 318a and the shaft 318b may be used to manipulate or select various elements displayed on the display, adjust the speaker volume, turn the watch 300 on or off, etc. The crown body 318a may be operatively coupled to circuitry (e.g., a processing unit) within the housing 322, but electrically isolated from the housing 322. The crown 318a may include conductive electrodes for measuring ECG or other health-related measurements.

[0083] The retaining bracket 394 can be positioned along the inner surface of the sidewall 322a. The retaining bracket 394, together with fasteners 396a and 396b, can be used to couple components of the modular sensing assembly 310 together. The button retainer 384 may include a coupling mechanism for coupling the button subassembly 380 to the retaining bracket 394 using fasteners 396a and 396b. For example, the button retainer 384 may include female threaded connectors 386a and 386b configured to engage threadedly with fasteners 396a and 396b via channels 390a and 390e. The button member 388 may include a coupling mechanism for coupling the button member 388 to the housing 322. For example, the button member 388 may include female threaded connectors 387a and 387b configured to engage threadedly with fasteners 397a and 397b via channels 390b and 390d.

[0084] Retaining bracket 394 and fasteners 396a, 396b can be used to secure the modular sensing assembly 310 to the housing 322. Coupling the retaining bracket 394 to the button retainer 384 can secure the modular sensing assembly 310 to the housing 322.
