Background Technology

[0002] Recently, due to consumer interest in personal health, a variety of personal health monitoring devices are being offered on the market. Recent advancements in the miniaturization of sensors, electronic devices, and power sources have made it possible to provide personal health monitoring devices—also known as "bio-tracking" or "bio-monitoring" devices—in very small sizes that were previously unrealistic.

[0003] These bio-monitoring devices can collect, acquire, and / or provide one or more of the following types of information: heart rate, calories burned, number of floors climbed and / or descended, location and / or direction, altitude, walking speed and / or distance traveled. In the case of wearable computing devices, the front or top surface is typically occupied by a large electronic display, which is often covered by an optically transparent cover made of a specific material (such as glass, polycarbonate, acrylic, etc.). This cover often requires sealing around its perimeter, so the electronic display cover becomes larger than the actual area of ​​the electronic display itself.

[0004] Accordingly, the present disclosure relates to a biosensor electrode integrated into the upper surface of a cover of such a wearable computing device, which provides an increased surface area of ​​the sensor and improved signal quality. By integrating the biosensor electrode into the cover, the user can access the sensor in a more ergonomic manner, allowing the user to contact the small surface with various limbs (palms, fingers, legs, etc.) without requiring high dexterity.

Additionally, the wearable computing device comprises a conductive component that electrically connects the biosensor electrode(s) to the printed circuit board through the electronic display module connector. Additionally, the conductive component defines a low-resistance path.

[0007] Another exemplary aspect of the present disclosure relates to a method for assembling a wearable computing device.

[0013] survey

[0014] In the case of wearable computing devices, the front or top surface is typically occupied by a large electronic display and is often covered by an optically transparent cover made of a specific material (such as glass, polycarbonate, acrylic, etc.). This cover often requires sealing around its perimeter, so the electronic display cover becomes larger than the actual area of ​​the electronic display itself. Accordingly, the present disclosure relates to a biosensor electrode integrated into the top surface of a cover of a wearable computing device to provide increased surface area of ​​the sensor and improved signal quality. By integrating the biosensor electrode into the cover, the user can access the sensor in a more ergonomic manner, allowing the user to contact the small surface with various limbs (palms, fingers, legs, etc.) without requiring high dexterity.

[0015] To activate a biosensor electrode formed on the upper surface of a cover, the sensor needs to be electrically connected to a sensing hub (including a main circuit) located on a system board within a wearable computing device. Accordingly, the present disclosure also relates to an improved conductive component located between the biosensor electrode and the main circuit of a wearable computing device. Accordingly, the present disclosure provides an effective and efficient electrical connection of a conductive component to a printed circuit board or a flexible circuit board and to the main circuit of a wearable computing device via an electronic display module. In particular, the improved conductive component of the present disclosure has low feed-through electrical resistance and does not require additional space. Furthermore, the integrated biosensor electrode facilitates the assembly process without increasing costs or compromising reliability.

[0016] For example, in the embodiments, direct or indirect connections using a conductive foam (such as anisotropic conductive film (ACF) and silver epoxy) and an adhesive may be used. In these embodiments, a physical vapor deposition (PVD) contact pad is positioned on the top surface and interposed between the sensor metal bottom of the cover and the top surface of the electronic display module. Next, a low-resistance conductive foam is placed between the sensor metal bottom and the PVD contact pad to connect the biosensor electrode to the PVD contact pad(s). Additionally, the PVD contact pad on the top surface is connected to a flexible printed circuit (FBC) via an electronic display module connector. The FBC is bonded to the top surface using an adhesive such as ACF by a conventional FPC bonding process. Furthermore, the electronic display module connector is fixed to the device body containing the main circuit.

[0017] In particular, by providing a conductive component between the biosensor electrode and the main circuit of the wearable computing device, for example, a wearable computing device with a compact and robust design can be obtained.

[0018] Now, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings.

[0019] Exemplary devices and systems

[0020] Now, referring to the drawings, FIG. 1 illustrates a perspective view of a wearable computing device (100) according to the present disclosure. In particular, as illustrated, the wearable computing device (100) may be worn on a person's forearm like a wristwatch. Also, as illustrated, the wearable computing device (100) comprises a housing (102) containing an electronic device associated with the wearable computing device (100). Also, as illustrated, the wearable computing device (100) includes one or more buttons (104) and an electronic display (106) accessible and / or viewable through the housing (102). In some embodiments, for example, the button(s) (404) may be implemented to provide a mechanism for activating a heart rate sensor to collect heart rate data. Also, in one embodiment, the electronic display (106) may cover an electronic device package (110) (also referred to herein as an electronic display module connector) that is also housed in the housing (102). Additionally, as illustrated, the wristband (108) can be integrated with the housing (102).

[0021] Now, referring to FIGS. 2 through 7, various drawings of a housing (102) of a wearable computing device (100) according to the present disclosure are illustrated. Specifically, FIG. 2 illustrates a plan view of one embodiment of the housing (102) according to the present disclosure. FIG. 3 illustrates a side view of one embodiment of the housing (102) according to the present disclosure. FIG. 4 illustrates an exploded side view of one embodiment of the housing (102) according to the present disclosure. FIG. 5 illustrates a transparent perspective view of one embodiment of the housing (102) according to the present disclosure. FIG. 6 illustrates a transparent plan view of one embodiment of the housing (102) according to the present disclosure. FIG. 7 illustrates a transparent perspective view of one embodiment of the housing (102) according to the present disclosure. FIG. 8 illustrates a rear view of one embodiment of an electronic device package (110) inside the housing (102) according to the present disclosure.

[0022] Additionally, as roughly illustrated in FIGS. 2 through 7, the housing (102) includes an outer cover (112) that defines the outermost upper surface (114) and the outer periphery (116). For example, in an embodiment, the outer cover (112) may be composed of glass, polycarbonate, acrylic, etc. Accordingly, particularly as illustrated in FIG. 7, the internal volume (118) is defined at least partially by the inner surface (120) of the outer cover. Additionally, as illustrated in FIGS. 5 and 7, the wearable computing device (100) may also include a seal (115) arranged along the outer periphery (116) of the outer cover (112). Accordingly, in this embodiment, as illustrated in FIG. 7, the internal volume (118) is defined by the inner surface (120) of the outer cover (112) and the inner edge (117) of the seal (115). Accordingly, as illustrated, the electronic display (106) and the electronic display module connector (110) can be arranged within an internal volume (118) as further described herein.

[0023] Additionally, as illustrated in FIGS. 2 through 7, the wearable computing device (100) further comprises at least one biosensor electrode, such as a first biosensor electrode (122) and a second biosensor electrode (124), which is positioned on the outermost upper surface (114) of the outer cover (112) and wraps around one or more side edges of the outer cover (112) relative to the internal volume (118) (e.g., see FIG. 7). Thus, as illustrated, in an embodiment, the wearable computing device (100) may comprise two sensor electrodes (122, 124) arranged in pairs. In such an embodiment, the two sensor electrodes (122, 124) may have an overlapping space over a display area.

[0024] For example, as illustrated in FIG. 7, in one embodiment, the biosensor electrode(s) (122, 124) wrap around the side edge of the outer cover (112) and the inner edge (117) of the seal (115) up to the inner volume (118). Additionally, in this embodiment, as schematically illustrated in FIG. 2 through 7, the first and second biosensor electrodes (122, 124) may also be spaced apart by one or more gaps (126). More specifically, as illustrated in FIG. 2, the first and second biosensor electrodes (122, 124) may be spaced apart through a plurality of gaps (126) on both sides of the outer cover (112). In other words, as illustrated, the two sensor electrodes (122, 124) may have a space in between to avoid the printed circuit board bonding area.

[0025] Additionally, as illustrated in FIG. 8, the wearable computing device (100) includes a printed circuit board (128) arranged within an internal volume (118), i.e., on the back surface of an electronic display (106). Accordingly, in one embodiment, as illustrated in FIG. 8 and FIG. 12, the first and second biosensor electrodes (122, 124) are arranged on both sides of the printed circuit board (128). Alternatively, as illustrated in FIG. 18, the first and second biosensor electrodes (122, 124) are arranged on the same side of the printed circuit board (128). Also, in certain embodiments, the biosensor electrode(s) (122, 124) described herein may each include a physical vapor deposition (PVD) sensor pad. Additionally, in one embodiment, the biosensor electrode(s) (122, 124) described herein may include an electrocardiogram (ECG) sensor, an electrodermal activity (EDA) sensor, or any other suitable sensor type.

[0026] Accordingly, the biosensor electrode(s) (122, 124) described herein may be connected via an inter-media material to an electronic display module connector (110) which may include a computing system configured to operate a wearable computing device (100). In particular, as illustrated in FIG. 9, a block diagram of an exemplary computing system (150) according to an exemplary embodiment of the present disclosure is illustrated. Also, as illustrated, in one embodiment, the computing system (150) includes a user computing device (152), a server computing system (160), and a training computing system (170) coupled to communicate via a network (180). Thus, in an embodiment, a component of the user computing device (152) may be part of the wearable computing device (100).

[0027] In particular, as illustrated, the user computing device (152) includes one or more processors (154) and memory (155). The one or more processors (154) may be any suitable processing device (e.g., processor core, microprocessor, ASIC, FPGA, controller, microcontroller, etc.) and may be a single processor or a plurality of processors that can be connected and operated. The memory (155) may include one or more non-transient computer-readable storage media such as RAM, ROM, EEPROM, EPROM, flash memory device, magnetic disk, etc. and combinations thereof. The memory (155) may store data (156) and instructions (157) that are executed by the processor (154) to cause the user computing device (152) to perform an operation.

[0028] In some embodiments, the user computing device (152) may store or include one or more models (158). For example, in an embodiment, the model(s) (158) may be or include various machine learning models, such as a neural network (deep neural network (DNN)) or other types of machine learning models including non-linear models and / or linear models. The neural network may include a feedforward neural network (FFNN), a regression neural network (RNN) (e.g., a long short-term memory regression neural network (LSTM-RNN)), a convolutional neural network (CNN), or other types of neural networks.

[0029] Accordingly, in some embodiments, the model(s) (158) may be received from the server computing system (160) via the network (180), stored in the user computing device memory (155), and then used or otherwise implemented by the processor(s) (154). Additionally or alternatively, one or more models (168) may be included in the server computing system (160) that communicates with the user computing device (152) according to a client-server relationship, or otherwise stored and implemented by said server computing system. Thus, the model(s) (158) may be stored and implemented in the user computing device (152) and / or the model(s) (168) may be stored and implemented in the server computing system (160).

[0030] The user computing device (152) may also include one or more user input components (159) that receive user input. For example, the user input component (159) may be a touch-sensing component (e.g., a touch-sensing display screen or a touchpad) that detects a touch of a user input object (e.g., a finger or a stylus). The touch-sensing component may serve to implement a virtual keyboard. Other exemplary user input components include a microphone, a traditional keyboard, or other means that enable the user to provide user input.

[0031] The server computing system (160) may be any type of computing device, such as a personal computing device (e.g., a laptop or desktop), a mobile computing device (e.g., a smartphone or tablet), a gaming console or controller, a wearable computing device, an embedded computing device, or any other type of computing device. Additionally, as illustrated, the server computing system (160) includes one or more processors (162) and memory (164). The processor(s) (162) may be any suitable processing device (e.g., a processor core, a microprocessor, an ASIC, an FPGA, a controller, a microcontroller, etc.) and may be a single processor or a plurality of processors that can be connected and operated. The memory (164) may include one or more non-transient computer-readable storage media, such as RAM, ROM, EEPROM, EPROM, a flash memory device, a magnetic disk, etc., and combinations thereof. The memory (164) can store data (165) and commands (166) that are executed by the processor (162) to cause the server computing system (160) to perform operations.

[0032] In some embodiments, the server computing system (160) includes one or more server computing devices or is otherwise implemented by one or more server computing devices. If the server computing system (160) includes multiple server computing devices, these server computing devices may operate according to a serial computing architecture, a parallel computing architecture, or some combination thereof.

[0033] As described above, the server computing system (160) may store or otherwise contain one or more models (168). For example, the model(s) (168) may be various machine learning models or otherwise contain them. Examples of machine learning models include neural networks or other multilayer nonlinear models. Examples of neural networks include feedforward neural networks, deep neural networks, regression neural networks, and convolutional neural networks.

[0034] A user computing device (152) and / or a server computing system (160) can train a model (158 and / or 168) through interaction with a training computing system (170) that is communicably connected via a network (180). The training computing system (170) may be separate from the server computing system (160) or may be part of the server computing system (160).

[0035] The training computing system (170) includes one or more processors (172) and memory (174). The processor(s) (172) may be any suitable processing device (e.g., processor core, microprocessor, ASIC, FPGA, controller, microcontroller, etc.) and may be a single processor or a plurality of processors that can be connected and operated. The memory (174) may include one or more non-transient computer-readable storage media such as RAM, ROM, EEPROM, EPROM, flash memory device, magnetic disk, etc. and combinations thereof. The memory (174) may store data (175) and instructions (176) that are executed by the processor (172) to cause the training computing system (170) to perform an operation. In some embodiments, the training computing system (170) includes one or more server computing devices or is otherwise implemented by one or more server computing devices. The training computing system (170) may also include a model trainer (177) that trains a machine learning model (158 and / or 168) stored in a user computing device (152) and / or a server computing system (160) using various training or learning techniques. In particular, in the embodiment, the model trainer (177) may train the model (158 and / or 168) based on a set of training data (178).

[0036] A model trainer (177) includes computer logic used to provide desired functions. The model trainer (177) may be implemented as hardware, firmware, and / or software that controls a general-purpose processor. For example, in some embodiments, the model trainer (177) includes a program file that is stored in a storage device, loaded into memory, and executed by one or more processors. In other embodiments, the model trainer (177) includes one or more computer-executable instruction sets stored in a computer-readable storage medium of a type such as RAM, a hard disk, or an optical or magnetic medium.

[0037] The network (180) may be any type of communication network, such as a local area network (e.g., intranet), a wide area network (e.g., the Internet), or a combination of several such networks, and may include any number of wired or wireless links. Generally, communication through the network (180) may be performed via any type of wired and / or wireless connection using various communication protocols (e.g., TCP / IP, HTTP, SMTP, FTP), encoding or format (e.g., HTML, XML), and / or protection schemes (e.g., VPN, secure HTTP, SSL).

[0038] Now, referring to FIGS. 10 through 20, the wearable computing device (100) of the present disclosure further comprises a conductive component (130) that electrically connects biosensor electrode(s) (122, 124) to a printed circuit board (128) through an electronic display module connector (110). In particular, the conductive component (130) described herein provides a low resistance path (e.g., less than about 50 ohms, particularly less than 10 ohms).

[0039] More specifically, as illustrated in FIGS. 10 through 17, the conductive component (130) is a double-sided conductive foam (132) or tape. In one embodiment, for example and particularly as illustrated in FIGS. 10, 11 and 14, the double-sided conductive foam (132) or tape may be interposed between the bottom surface (138) of the outer cover (112) and the top surface (140) of the electronic display (106). In such an embodiment, particularly as illustrated in FIG. 14. The signal path indicated by the arrow (123) passes through the electronic display (106) first and then through the printed circuit board (128). Thus, as illustrated in FIGS. 10, 11 and 14. In a specific embodiment, the electronic display (106) may be connected through the printed circuit board (128) by anisotropic conductive film (ACF) bonding. The ACF bonding used here generally refers to a lead-free, environmentally friendly adhesive interconnect film system or paste that can be used to create electrical and mechanical connections. Additionally, as illustrated, the conductive line(s) (142) and conductive component (130) connected to the biosensor electrode(s) (122, 124) are connected to a printed circuit board (128) to transmit a detection signal to an electronic device package (110).

[0040] In an alternative embodiment, as illustrated in FIGS. 15 through 17, a double-sided conductive foam (132) or tape may be placed on the upper surface (121) of a printed circuit board (128). In this embodiment, as illustrated, the electronic display (106) becomes part of the printed circuit board (128) (i.e., its upper surface). Thus, particularly as illustrated in FIG. 17, the double-sided conductive foam (132) or tape is configured to be placed on the upper surface (121) of the printed circuit board (128) (e.g., on the wing-side upper surface of the electronic display (106). In this embodiment, particularly as illustrated in FIG. 17, the signal path indicated by the arrow (125) proceeds through the electronic display (106) and directly through the printed circuit board (128).

[0041] Alternatively, as illustrated in FIGS. 19 and 20, the conductive component (130) is a double-sided conductive tape (134) or film. In this embodiment, as illustrated, the conductive tape (134) or film may be directly attached to the biosensor electrode(s) (122, 124) to electrically connect the biosensor electrode(s) (122, 124) to a printed circuit board (128). More specifically, as illustrated, the biosensor electrode(s) (122, 124) wrap around the side edge of the outer cover (112) up to the inner volume (118) so that the first end of the conductive tape (134) or film is fixed to the end of the biosensor electrode(s) (122, 124) and the opposite end of the conductive tape (134) or film is fixed directly to the printed circuit board (128) (or to a conductive component in direct contact with the printed circuit board (128). Additionally, in this embodiment, the conductive component (130) may include a separate conductive tape or a single conductive tape having two conductive lines.

[0042] Now, referring to FIG. 21, the conductive component (130) is an ACF (anisotropic conductive film or paste) bonding (135). In this embodiment, for example, the ACF bonding (135) may be directly attached to the biosensor electrode(s) (122, 124) to electrically connect the biosensor electrode(s) (122, 124) to a printed circuit board (128). In this embodiment, the ACF bonding (135) may be used alone or in combination with a conductive tape (134) or film that provides additional support. Thus, in this embodiment, as shown in step (1), the ACF bonding (135) may be connected to the biosensor electrode(s) (122, 124) located on a hard glass surface. As shown in step (2), an electronic display (106) may be laminated on top of the ACF bonding (135). Additionally, as shown in step (3), the ACF bonding (135) can be connected to the printed circuit board (128) or any suitable location that can ultimately be electrically connected to the printed circuit board (128). Such connection can be completed, for example, using soldering, connectors, springs, fasteners, etc.

[0043] In another embodiment, as illustrated in FIGS. 22 and 23, the conductive component (130) is a conductive adhesive (136) through direct contact, such as silver epoxy. In another embodiment, the conductive component (130) may be a single-sided conductive tape, a single-sided conductive foam, an anisotropic conductive film, or a combination thereof.
