## Title
Wireless enabled cap for a data-capable device

## Abstract

A housing (e.g., a wearable structure) includes one or more sensors operative to capture sensor data and a plug operative to electrically communicate data (e.g., the sensor data) to another device via a hard wired connection. A wirelessly enabled cap may be removably coupled with the housing and may include: a cavity operative to house the plug; a RF chip disposed within the housing; and one or more antennas electrically coupled with the chip. The chip is operative to wirelessly communicate data (e.g., the sensor data) in accordance with one or more wireless communication protocols (e.g., short-range, long-range, near field). The one or more antennas may form an exterior portion(s) of the housing and/or may be embedded in a portion(s) of the housing. The chip may be passive powered from an external RF source (e.g., an externally generated RF signal electrically coupled with the chip through one or more antennas).

The described techniques may be varied and are not limited to the examples or descriptions provided.
FIG. 1 illustrates an exemplary system of wireless devices including a data-capable band implemented with a wireless enabled cap, according to some examples. Here, system 100 includes data-capable band (hereinafter “band”) 102, cap 104, wireless tag 106, microchip 108, antenna 110, mobile device 112, laptop 114, tablet 116, headset 118 (e.g., worn on a head or an ear of a user 130) and miscellaneous application 120. In some examples, band 102 may be implemented as a data-capable strapband as depicted and/or described in the above mentioned Co-Pending U.S. patent applications, which are incorporated herein by reference in their entirety for all purposes. Microchip 108 may comprise a RF chip, RF circuitry, a chip, a tag, RF tag, a NFC chip, a NFC tag chip, an ASIC, or other device. For example, microchip 108 may comprise a semiconductor die including analog and/or digital circuitry for RF communications according to one or more wireless protocols and/or standards.
For example, band 102 may be implemented as a wearable data capture device, including one or more sensors (e.g., sensor(s) 418 in FIG. 4 and the like), or a sensor array, (e.g., active and/or passive sensors) for capturing sensor data relating to temperature, environment, time, motion, activity, accelerometry, physiology, medical condition, biometric conditions, and the like. In some examples, band 102 may be configured to collect local sensor data using said sensor array, which may include, without limitation, an accelerometer, an altimeter/barometer, a light/infrared (“IR”) sensor, a pulse/heart rate (“HR”) monitor, an audio sensor (e.g., microphone, transducer, or others), a pedometer, a velocimeter, a global positioning system (GPS) receiver, a location-based service sensor (e.g., sensor for determining location within a cellular or micro-cellular network, which may or may not use GPS or other satellite constellations for fixing a position), a motion detection sensor (e.g., a single or multi-axis accelerometer and/or a gyroscope), an environmental sensor, one or more biometric sensors (e.g., heart rate, respiration, body temperature, GSR, EMG, bioimpedance, arousal of the sympathetic nervous system—SNS, etc.), a chemical sensor, an electrical sensor, or mechanical sensor, and the like, installed, integrated, or otherwise implemented on band 102.
In other examples, band 102 also may be configured to capture data from distributed sources (e.g., by communicating with mobile computing devices, other bands 102, mobile communications devices, wireless client devices (e.g., a smartphone or tablet), computers, laptops, tablets, pads, distributed sensors, GPS satellites, or the like) for processing with sensor data. Band 102 may wirelessly transmit sensor data (e.g., motion signals, biometric signals) to external wireless devices and/or wireless systems (e.g., other bands 102, wireless client devices, etc.), and may wirelessly receive data including sensor data from external wireless devices and/or wireless systems (e.g., from other bands 102, wireless client devices, etc.). Processing and/or storage of data (e.g., sensor data) may occur internal to band 102, external to band 102 or both. For example, resource 199 may be an external system that may include or have access to a data storage system 197 (e.g., a hard drive, SSD, RAID, NAS) and a compute engine 198 (e.g., a PC, a server, laptop, tablet, etc.). As another example, device 112 or device 114 may be an external system that may include data storage and computing resources that may be accessed by band 102.
In some examples, one or both of band 102 and cap 104 may be configured to communicate wirelessly 126 with other wireless devices, wireless systems, or applications, including, without limitation, mobile device 112 (e.g., a wireless client device such as a smartphone), laptop 114, tablet or pad 116, headset 118, miscellaneous application 120, one or more other bands 102a, resource 199 (e.g., the Cloud or the Internet), and the like. In some examples, cap 104 and/or band (102, 102a) may wirelessly communicate with other wireless devices or systems using another wireless device (e.g., 112 or 116) as an intermediary transceiver (e.g., a RF relay station), such as wireless communication between band/cap (102, 104) and resource 199 via device 112 using wireless links 126 and 146, or wireless communication between band/cap (102, 104) and band/cap 102a/104 via device 116 using wireless links 126 and 136. In some examples, wireless tag 106 may be implemented as a wireless controller configured to exchange data with said other wireless devices, for example, using short-range communication protocols (e.g., Bluetooth® (BT), Bluetooth® Low Energy (BTLE), ultra wideband, near field communication (NFC), or the like) or longer-range communication protocols (e.g., satellite, mobile broadband (e.g., 5G, 4G, 3G, 2G or the like), other cellular networks, GPS, one or more varieties of IEEE 802.x such as 802.11a/b/g/n (WiFi), WiMAX, other wireless local area network (WLAN), and the like). In some examples, cap 104 may be enabled with near-field communications (NFC) capabilities (e.g., from a NFC chip), and thus may be able to establish a two-way radio communication with another NFC-enabled device through touching the two devices together, or bringing them into close enough proximity to establish an NFC connection (e.g., a few centimeters or other close distance sufficient for establishing an NFC link).
For example, cap 104 may include a wireless or NFC tag, card or chip (hereinafter “tag”) 106, which may be configured to provide stored data, including data stored using microchip 108, using a radio frequency (RF) field. In some examples, wireless tag 106 may include microchip 108 and antenna 110, which may be electrically coupled to (e.g., able to transfer electrical energy or an electrical signal to and from) each other. In some examples, microchip 108 also may be electrically coupled to one or more other components of band 102. In some examples, wireless tag 106 may be implemented as an unpowered NFC tag, which may be powered or activated by coming within a threshold proximity (e.g., a few centimeters or other close distance sufficient for establishing an NFC link) of a powered NFC device (e.g., band 102, mobile device 112, laptop 114, tablet 116, headset 118, miscellaneous application 120, or the like). Once within a threshold proximity of a powered NFC device, wireless tag 106 may take one or more actions including but not limited to provide data, such as a biometric identifier, other identifier, verification information, authentication information, control data to cause an application (e.g., run or operated using mobile device 112, laptop 114, tablet 116, headset 118, miscellaneous application 120, or the like) to open, to pair Bluetooth® devices, to sync Bluetooth® devices, to turn on Bluetooth® or WiFi capabilities in band 102, to accept programming, to accept re-programming, to accept configuration, to accept re-configuration, to accept software updates, to accept operating system (OS) updates, to sync band 102 with an application (e.g., run or operated using mobile device 112, laptop 114, tablet 116, headset 118, miscellaneous application 120, or the like), to modify settings on another device, or the like), or other discreet stored data, to one or more of band 102, mobile device 112, laptop 114, tablet 116, headset 118, resource 199, miscellaneous application 120. In other examples, wireless tag 106 may include other wireless controller circuits. In still other examples, the quantity, type, function, structure, and configuration of the elements shown may be varied and are not limited to the examples provided. In still other examples, the quantity, type, function, structure, and configuration of the elements shown may be varied and are not limited to the examples provided.
In some examples, microchip 108 may be a passive electrical device that may not receive electrical power directly from band 102 or any circuitry or power source(s) in band 102. As one example, microchip 108 may include circuitry to passively receive electrical power from an external source other than circuitry or power sources in the band 102. The external source may be an externally generated RF signal that is electrically coupled with the microchip 108 through an antenna, such as antenna 110, for example. A device having a radio or the like that may generate an RF signal, such as devices 112, 114, 116, or 118 depicted in FIG. 1, a device configured for NFC, a device configured for very short range (e.g., in near field proximity of a wireless client device(s)) RF communication, or other RF/wirelessly enabled device, may be the source of the externally generated RF signal, for example. Microchip 108 may be disposed within the housing and configured to electrically communicate stored data in accordance with one or more short-range wireless communication standards and/or protocols. Energy from the externally generated RF signal may be received by the antenna (e.g., 110) and electrically coupled with microchip 108 as a signal. Circuitry in the microchip 108 may convert the received signal into electrical power to power the microchip 108. A close or very close proximity (e.g., in a near field proximity) between a device that generates the externally generated RF signal and the antenna may be necessary for a received signal strength (e.g., RSSI) at the antenna to be of sufficient power to generate electricity within microchip 108 when the externally generated RF signal is coupled with the antenna. For example, as described above, the microchip (e.g., its antenna 110 or the like) coming within a threshold proximity (e.g., a few centimeters or other close distance sufficient for establishing an NFC link) of a powered NFC device or other device that may generate a RF signal external to the band 102, may cause microchip 108 to be powered up and take one or more actions as described herein. The antenna 110 may comprise a flexible printed circuit (FPC) antenna or may be implemented using a conductive ink as described herein (e.g., see 1230 in FIG. 12). The FPC antenna may include one or more electrically conductive structures and/or patterns formed on a FPC dielectric material or a flux field directional material (FFDM), for example.
In some examples, band 102 may be implemented with cap 104, which may be removably coupled to band 102. As used herein, “coupled” may be used to refer to electrical coupling, physical coupling, or both. For example, cap 104 may be configured to snap onto and off of an end of band 102. In another example, cap 104 may be tethered or leashed (not shown) to band 102 such that it may be uncapped, and still remain coupled to band 102. In some examples, cap 104 may be configured to cover a plug (e.g., plug 212 in FIG. 2, or the like) at an end of band 102. In some examples, cap 104 may include one or more housings and a plate forming a top surface of cap 104, said plate or top surface of cap 104 configured to receive material, for example, as a printed material deposited in the form of a logo, name or other image or text (see, e.g., plate 204 in FIG. 2). In other examples, said plate or top surface of cap 104 may be integrally molded as part of an outer housing of cap 104. In some examples, wireless tag 106 may include microchip 108 and antenna 110. In some examples, microchip 108 may be configured to store at least 128 bytes, and up to 2,000 bytes or more, of data, and may be configured to operate at a frequency of 13.56 MHz or 13.6 MHz according to an NFC standard. In some examples, microchip 108 may be NFC Forum Type 2 tag compliant, NFC Forum Type 4 tag compliant, or the like. Other examples include NFC standards maintained by the NFC Forum of Wakefield, Mass. In still other examples, the quantity, type, function, structure, and configuration of the elements shown may be varied and are not limited to the examples provided.
FIG. 2 illustrates a diagram depicting an exemplary wireless enabled cap for a data-capable band, according to some examples. Here, diagram 200 includes cap 202, plate 204, band 206, microchip 208, multi-purpose antenna 210, plug 212 and plug base 214. Like-numbered and named elements may describe the same or substantially similar elements as those shown in other descriptions. In some examples, cap 202 may include an inner housing 216 and an outer housing 218. In some examples, inner housing 216 and outer housing 218 may be integrally molded, for example, to form a single housing. In other examples, they may be molded separately. In some examples inner housing 216 may fit within outer housing 218. In some examples, inner housing 216 may have a cavity (not shown) configured to receive plug 212, and in some examples, plug base 214 as well. In some examples, an end of housings 216 and 218 may have an opening (not shown) leading into said cavity, said opening configured to receive plug 212. In some examples, plug 212 may be coupled to an end of band 206, for example at plug base 214, and be configured to send, receive or otherwise transfer data (e.g., sensor data, identification data, verification data, and the like) to one or more other devices (e.g., mobile device 112, laptop 114, tablet 116, headset 118, miscellaneous application 120 in FIG. 1, and the like) equipped with a socket configured to receive plug 212 and to receive plug 212 for data exchange. In some examples, plug 212 may be implemented as a connector including but not limited to a TRRS-type, TRS-type or TS-type analog audio plug (e.g., 3.5 mm, 2.5 mm or the like), a Universal Serial Bus (USB) type (e.g., micro USB, mini USB, etc.), or other types of analog or digital plugs (e.g., for audio and/or video), which may be used in connection with firmware and software that allow for the transmission of audio tones to send or receive encoded data, which may be performed using a variety of encoded waveforms and protocols, without limitation.
In some examples, cap 202 and plate 204 may be molded using any type of suitable material, including plastics, thermoplastics, thermoplastic elastomers (TPEs), polymers, elastomers, or any other organic or inorganic material. The material may be molded to form 202 and/or 204, for example. In some examples, cap 202 and plate 204 may be integrally molded as a monolithic cap. In some examples, microchip 208 may be mounted on (e.g., using insert molding, other molding techniques, or the like), embedded within, or otherwise disposed on, (hereinafter collectively “disposed on”) any side or surface (e.g., interior or exterior side) of, or within any wall of, inner housing 216 or outer housing 218. In some examples, multi-purpose antenna 210 may be disposed on plate 204, which may be configured to cover, or form a top side and surface of, or otherwise couple with, cap 202. In some examples, multi-purpose antenna 210 may be formed using conductive ink embedded, or disposed, onto plate 204, for example, in the shape of a logo or text (e.g., see 1230 in FIG. 12). In this way, multi-purpose antenna 210 may serve decorative, informative, and data exchange purposes. For example, conductive ink may be used to print a company name, a slogan, a product name, a Trademark, a Service Mark, an image, icon, artwork, ASCII characters, text, other stylized logo, or the like, in one or more colors, with the conductive ink also serving as an antenna. Plate 204 or some other substrate may be made from and electrically non-conductive material including but not limited to plastic, rubber, silicon, glass, a synthetic material, a composite material, Teflon, PVDF, or the like, just to name a few. The conductive ink (e.g., for multi-purpose antenna 210) may be printed, screen printed, sprayed, or otherwise formed or deposited on the plate 204 or substrate. In some examples, multi-purpose antenna 210 may be electrically coupled to (e.g., able to transfer electrical energy or an electrical signal to and from) microchip 208, directly or indirectly. In other examples, an antenna may be implemented elsewhere on cap 202, apart from a logo, either on plate 204 or on a side or surface of cap 202 (see, e.g., antennas 308-312c in FIG. 3, and the like). In still other examples, the quantity, type, function, structure, and configuration of the elements shown may be varied and are not limited to the examples provided.

In some examples, cap 302 may include antenna 308 and microchip 314 disposed on any surface of inner housing 302a. In other examples, antenna 308 and microchip 314 may be disposed on other surfaces (e.g., inner or outer, side or bottom, or the like) of inner housing 302a. In still other examples, antenna 308 and microchip 314 may be embedded into a top side, or other side of inner housing 302a. In other examples, antenna 308 may be inserted or otherwise positioned in an opening of inner housing 302a during a manufacturing step, such as a molding process, for example.

In still other examples, antennas 312a-312c may be disposed on a side of outer housing 306b. In some examples, cap 306 also may include microchip 318, disposed on a side (e.g., inner or outer, side, top or bottom, or the like) of outer housing 306b. In other examples, microchip 318 may be disposed on a side of inner housing 306a. In some examples, antennas 312a-312c may be electrically coupled to microchip 318.

FIG. 5 illustrates an exemplary computing platform suitable for a data-capable band implemented with a wireless enabled cap, according to some examples. In some examples, computing platform 500 may be used to implement computer programs, applications, methods, processes, algorithms, or other software to perform the above-described techniques. Computing platform 500 includes a bus 502 or other communication mechanism for communicating information and/or signals, which interconnects subsystems and devices, such as one or more processors 504, system memory 506 (e.g., RAM, Flash, etc.), storage device 508 (e.g., ROM, etc.), a communication interface 513 (e.g., an Ethernet and/or wireless controller, a Bluetooth controller, etc.) to facilitate communications via a port on communication link 521 to communicate, for example, with a computing device, including mobile computing and/or communication devices with processors and/or wireless communication (e.g., 126, 136, 146) with one or more wireless devices/systems, and an NFC tag 510, including antenna 512 and NFC chip 514, to facilitate direct communication with an NFC-enabled device. Processor 504 may be implemented with one or more central processing units (“CPUs”), such as those manufactured by Intel® Corporation, or one or more virtual processors, as well as any combination of CPUs and virtual processors. Computing platform 500 exchanges data representing inputs and outputs via input-and-output (I/O) devices 501, including, but not limited to, keyboards, mice, touch pad, audio inputs (e.g., speech-to-text devices), user interfaces, displays, monitors, cursors, gesture recognition, image capture device (e.g., video and/or still camera), proximity detection sensors, touch-sensitive displays, touch-screen, LCD, OLED, LED, or other types of displays, speakers, microphones, media players and other I/O-related devices.
According to some examples, computing platform 500 performs specific operations by processor 504 executing one or more sequences of one or more instructions stored in system memory 506 (e.g., a non-transitory computer readable medium such as Flash memory or the like), and computing platform 500 may be implemented in a client-server arrangement, peer-to-peer arrangement, or as any mobile computing device, including smart phones and the like. Such instructions or data may be read into system memory 506 from another non-transitory computer readable medium, such as storage device 508. In some examples, hard-wired circuitry may be used in place of or in combination with software instructions for implementation. Instructions may be embedded in software or firmware. The term “computer readable medium” refers to any non-transitory medium that participates in providing instructions to processor 504 for execution. Such a medium may take many forms, including but not limited to, non-volatile media and volatile media. Non-volatile media includes, for example, optical or magnetic disks and the like. Volatile media includes dynamic memory, such as system memory 506.
Common forms of non-transitory computer readable media may include, for example, floppy disk, flexible disk, hard disk drive (HDD), solid state disk (SSD), magnetic tape, any other magnetic medium, CD-ROM, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, RAM, PROM, EPROM, Flash Memory, FLASH-EPROM, any other memory chip or cartridge, or any other medium from which a computer may read. Instructions may further be transmitted or received using a transmission medium. The term “transmission medium” may include any tangible or intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible medium to facilitate communication of such instructions. Transmission media includes coaxial cables, copper wire, and fiber optics, including wires that comprise bus 502 for transmitting a computer data signal.
In some examples, execution of the sequences of instructions may be performed by computing platform 500. According to some examples, computing platform 500 may be coupled by communication link 521 (e.g., a wired network, such as LAN, PSTN, or any wireless network) to any other processor to perform the sequence of instructions in coordination with (or asynchronous to) one another. Computing platform 500 may transmit and receive messages, data, and instructions, including program code (e.g., application code) through communication link 521 and communication interface 513. Received program code may be executed by processor 504 as it is received, and/or stored in memory 506 or other non-volatile storage for later execution.
In the example shown, system memory 506 may include various modules that include executable instructions to implement functionalities described herein. As depicted in FIGS. 1-4 herein, the structures and/or functions of any of the above-described features may be implemented in software, hardware, firmware, circuitry, or any combination thereof. Note that the structures and constituent elements above, as well as their functionality, may be aggregated or combined with one or more other structures or elements. Alternatively, the elements and their functionality may be subdivided into constituent sub-elements, if any. As software, at least some of the above-described techniques may be implemented using various types of programming or formatting languages, frameworks, syntax, applications, protocols, objects, or techniques. For example, at least one of the elements depicted in FIG. 4 may represent one or more algorithms. Or, at least one of the elements may represent a portion of logic including a portion of hardware configured to provide constituent structures and/or functionalities.
As hardware and/or firmware, the above-described structures and techniques may be implemented using various types of programming or integrated circuit design languages, including but not limited to hardware description languages, such as any register transfer language (“RTL”) configured to design field-programmable gate arrays (“FPGAs”), application-specific integrated circuits (“ASICs”), multi-chip modules, digital circuitry, analog circuitry, mixed-analog-digital circuitry, radio frequency (RF) circuitry, or any other type of integrated circuit. At least one of the elements in FIG. 4 may be implemented in one or more computing devices that include one or more circuits, and thus may represent one or more components of hardware. Or, at least one of the elements may represent a portion of logic including a portion of circuit configured to provide constituent structures and/or functionalities.
According to some embodiments, the term “circuit” may refer, for example, to any system including a number of components through which current flows to perform one or more functions, the components including discrete and complex components. Examples of discrete components include transistors, resistors, capacitors, inductors, diodes, and the like, and examples of complex components include memory, processors, analog circuits, digital circuits, and the like, including field-programmable gate arrays (“FPGAs”), application-specific integrated circuits (“ASICs”). Therefore, a circuit may include a system of electronic components and logic components (e.g., logic configured to execute instructions, such that a group of executable instructions of an algorithm, for example, and, thus, is a component of a circuit). According to some embodiments, the term “module” may refer, for example, to an algorithm or a portion thereof, and/or logic implemented in either hardware circuitry or software, or a combination thereof (e.g., a module may be implemented as a circuit). In some embodiments, algorithms and/or the memory in which the algorithms are stored are “components” of a circuit. Thus, the term “circuit” may also refer, for example, to a system of components, including algorithms. These may be varied and are not limited to the examples or descriptions provided.
FIG. 6 illustrates an exemplary flow for transmitting an instruction to perform an action using a wireless enabled cap, according to some examples. Here, flow 600 begins with receiving, by a wireless enabled cap, a wireless signal using a multi-purpose antenna (602). In some examples, said wireless signal may be a RF signal. In some examples, wireless enabled cap may include one or more housings, and a wireless tag or controller, as described herein. For example, said wireless enabled cap may include an NFC tag having a microchip and an antenna. In some examples, said multi-purpose antenna may be implemented to serve multiple functions, including sending and receiving radio signals, as well as decorative or informative functions, where the antenna is formed using electrically conductive ink, as described herein. Once a wireless signal is received, an instruction may be generated using circuitry implemented in the wireless enabled cap (604). In some examples, such circuitry may be implemented as a wireless-to-wired converter. In some examples, said circuitry may be implemented as part of an NFC tag. In some examples, the instruction may be responsive to an NFC signal from another NFC-enabled device. For example, the instruction may include data associated with a biometric identifier, other identifier, verification information, authentication information, control data, or other stored data. In some examples, the instruction also may include logic configured to perform one or more functions, for example, to cause an application to open, to generate a pairing between Bluetooth® devices, to sync Bluetooth® devices, to turn on Bluetooth® or WiFi capabilities in a band, to sync a band with an application on another device, to modify settings on a band or another device, or the like. The instruction may be transmitted using a communication channel, the instruction configured to cause a device to perform an action (606). In some examples, the communication channel may be a wired communication channel, for example, using one or more contacts configured to couple to an audio plug or a circuit implemented in a band. In other examples, the communication channel may be wireless, for example, using a short-range communication protocol, as described herein. In other examples, the above-described process may be varied in steps, order, function, processes, or other aspects, and is not limited to those shown and described.
Here, in flow 600, at the stage 602, the receiving the wireless signal by the wireless cap using the multipurpose antenna (e.g., 110) may include the wireless signal coupling with the antenna to generate a signal that is electrically coupled with the microchip 108 to cause the microchip 108 (e.g., the passively powered microchip) to be powered by the signal while the signal is persistent, as was described above. The electrical power generated by the wireless signal coupling with the antenna may operate to power the microchip 108 to generate the instruction using circuitry at the stage 604 and/or transmit the instruction at the stage 606.
Attention is now directed to FIGS. 7A and 7B were partial cross-sectional views 700a and 700b, respectively, of a data-capable device 702 (e.g., a wearable structure such as a data-capable band, wearable device, a smart watch, etc.) and a wireless enabled cap 704 connected with the device 702 (band 702 hereinafter) are depicted. In some examples, wireless enabled cap 704 may include additional structure and/or components than those described above for wireless enabled cap 104. In other examples, wireless enabled cap 704 may exclude structure and/or components described above for wireless enabled cap 104. A chassis 760 of the data-capable band 702 may be configured to connect at least a portion of the band 702 with a body portion 701 (depicted in cross-section) of a user (not shown). Body portion 701 may include but is not limited to an arm, a leg, a wrist, a neck, an ankle, abdomen, torso, a calf, a thigh, triceps, or bicep, for example. Data-capable band 702 may be donned on body portion 701 using a variety of methods including but not limited to wrapping or flexing band 702 around a partial and/or full circumference of the body portion 701, strapping band 702 to the body portion 701, just to name a few. Interior portions of chassis 760 may include structures denoted generally as 761 that may include but are not limited to electronic systems (e.g., in FIGS. 4 and 5), circuitry, sensors, power sources, and structure that allows band 702 to retain its shape when donned by a user. Band 702 is a non-limiting example of a device 702 that may be coupled with a wirelessly enabled cap, such as caps 104, 704, and other caps described herein, and the present application is not limited to the examples of devices depicted herein.
Cap 704 is depicted mounted to the band 702. Mounting may be accomplished by inserting plug 212 into a cavity 720 of cap 704. Cap 704 may include one or more structures (e.g., 811) configured to retain the cap 704 on the plug as will be described below in reference to FIGS. 8A-8B. For example, the structures may be configured to grip plug base 214 with a force (e.g., a friction force) that retains the cap on the band 702, but also allows for the cap 704 to be removed when necessary. Plug 212 may be electrically coupled with one or more systems and/or circuitry in band 702 using a connector portion 708. Cap 704 may comprise a variety of materials including but not limited to electrically conductive materials, electrically non-conductive materials, plastics, metals, metal alloys, composites, etc. As one example, cap 704 may include a first material 733 having cavity 720 formed therein to receive plug 212 and having another cavity 740 (depicted inside dashed line) formed therein to receive tag 106 and/or microchip 108 denoted as chip 750, a second material 731 that may surround at least a portion of the first material 733, and an antenna 730 which may be positioned between the first 733 and second 731 materials. Antenna 730 (e.g., antenna 110) may be routed around one or more surfaces of the first material 733 and may be coupled with electrical nodes on chip 750 using soldering, crimping, surface mounting, etc. Antenna 730 may be formed from a variety of materials including but not limited to a flexible printed circuit board, a flexible electrically conductive substrate, an electrically conductive substrate, for example. The first material 733, the second material 731 or both may be made from electrically non-conductive materials, such as plastics, rubber, composites, synthetics, organic and/or inorganic materials, or other materials. Material selection for 731 and/or 733 may be based on materials that will not impair (e.g., substantially attenuate or block) RF signals from being transmitted and/or received by antenna 730. Cap 704 may optionally include a structure 735 that may be coupled with the second material 731 (e.g., by glue, adhesives, fastener, etc.). Structure 735 may have a functional purpose (e.g., as an antenna), an esthetic purpose (e.g., a brand logo, to add color(s), a fashionable design, etc.) or both. Orientation of cap 704 relative to band 702 when mounted on the band 702 may be application dependent and is not limited to the examples depicted in FIGS. 7A-7B. Furthermore, arrangement of the other components of cap 704 (e.g., 730, 750, 740, 720, 735, etc.) may be application dependent and is not limited to the examples depicted in FIGS. 7A-7B.
Chip 750 may comprise a wireless component such as a NFC chip, NFC tag, or the like. For example, chip 750 may comprise a NTAG203 NFC chip or other device for use in a NFC enabled device, such as cap (104, 704, 904). Chip 750 may conform to a protocol or standard such as that of the NFC Forum or other NFC standards for wireless devices. Chip 750 may be an ASIC that is custom designed for an application specific NFC device. Dimensions for chip 750 will be application specific; however, a typical die (e.g., from a semiconductor wafer) for chip 750 may be about 5 mm or less on a side (e.g., 2 mm by 2 mm or less). Accordingly, a cavity (e.g., 740, 940) in which the chip 750 is mounted in cap (104, 704, 904) may be dimensioned accordingly to accommodate mounting of the chip 750 in the cavity or other structure in the cap (104, 704, 904) that receives the chip 750. Chip 750 may comprise one of the above described chips (e.g., 108, 208, 318, 408, or 514) for a wireless NFC tag (e.g., 510, 404, or 106). The cap 704 when mounted or otherwise connected with a device, such as band 702 (see FIG. 7A) for example, may wirelessly communicate (e.g., 126, 136) with other wireless devices, wireless client devices, smartphone, tablets, pads, wireless networks (e.g., WiFi, WiMAX, one or more varieties of IEEE 802.x, Bluetooth, Bluetooth Low Energy, NFC, or others, etc.).
FIGS. 8A and 8B depict profile 800a and cross-sectional 800b views, respectively of another example of wireless enabled cap 704. In FIG. 8A, an entrance end of cap 704 may include one or more structures 811 configured to engage plug 212 (e.g., grip plug base 214) when plug 212 is inserted into cavity 720. A back surface 720b of cavity 720 may be operative to prevent mechanical and/or electrical contact between plug (212, 912) and chip 750 and/or antenna 730. Antenna 730 (depicted in dashed outline) may be positioned below second material 731 and between first material 733 or embedded in first material 731 as is depicted in greater detail in FIGS. 8B and 8C. Antenna 730 may be routed over and/or between one or more surfaces of materials 733 and/or 731. For example, antenna 730 may be routed over a first portion of first material 733 and over a second portion of first material 733, with the second portion positioning the antenna 730 for electrical connection with chip 750 in cavity 740. Here, antenna 730 may be bent or folded over an edge 821 of the first material 730 to position a portion of antenna 730 on the second portion of the first material 733. Second material 731 may include a cavity 841 configured to receive a portion of structure 735. Structure 735 may include indicia 835 that may be functional, esthetic or both. For example, indicia 835 may be a logo, a trademark, artwork, instructions, an image, a name, initials, a nick name, a monogram, a model number, a serial number, etc., just to name a few. Materials for 731 may include but are not limited to an electrically conductive substrate, an electrically conductive flexible substrate, metal, metal alloys, a plastic substrate having electrically conductive structures, FPCB, and polyimide, for example.
In FIG. 8C, two examples of configurations (800c and 800d) of antenna 730 embedded in the first material 731 of cap 704 are depicted. Configuration 800d depicts several different example configurations for the antenna embedded in cap 704 as will be described below. In configuration 800c, antenna 730 may be embedded in first material 731 and may span along top and side portions of the first material 731. In configuration 800d, antenna 730 may be embedded in first material 731 and may span along a top portion of the first material 731 (e.g., see antenna 730 which may be embedded in top portion of material 1131 in configuration 1100a of FIG. 11). Alternatively, in configuration 800d, antenna 730 may be embedded in first material 731 and may span along another portion of the first material 731, such as a side portion as depicted by a vertical position of an antenna 730a along the side portion (e.g., see antenna 730a which may be embedded in side portion of material 1131 in configuration 1100a of FIG. 11), in contrast to the horizontal position of the antenna 730 along the top portion in configuration 800d. 
In some examples, antenna 730 may be embedded in the structure 735 as depicted by antenna 730b. In yet other examples, antenna 730 may be embedded in the first material (e.g., 730 and/or 730a) and may also be embedded in the structure 735 as depicted by antenna 730b in configuration 800d (e.g., see antennas 730, 730a, 730b which may be embedded in materials 1131 and/or 1135 in configuration 1100a of FIG. 11). Antennas (730, 730a, 730b, 730c) may be electrically coupled with chip 750 using any suitable means including soldering, crimping, direct contact of their respective nodes, etc. Materials for 731 and/or 735 may be selected for properties consistent with reliable RF signal transmission and/or reception for antennas (730, 730a, 730b, 730c).
Moving on to FIGS. 9A-9C where front profile 900a, back profile 900b, and cross-sectional 900c views of a wireless enabled cap 904 including an antenna 930 positioned on an exterior portion of the wireless enabled cap 904 are depicted. In some examples, wireless enabled cap 904 may include additional structure and/or components than those described above for wireless enabled cap 104 and/or 704. In other examples, wireless enabled cap 904 may exclude structure and/or components described above for wireless enabled cap 104 and/or 704. A first material 933 may serve as a foundation (e.g., a mandrel or preform) upon which the antenna 930 may be disposed. For example, first material 933 may include arcuate surfaces 941 and antenna 930 may be conformally coupled with one or more surfaces of the first material 933 such that antenna 930 conformally covers the one or more surfaces. The first material 933 may include the cavity 730 through which plug 212 may be inserted 921 to mount the cap 904 to the band (102, 202, 702). Antenna 930 may be made from a flexible material, such as a flexible printed circuit board material, a flexible electrically conductive material, or other suitable materials. Antenna 930 may be made from an inflexible material that is shaped (e.g., by pressing, stamping, machining, rolling, or other machine processes) to conform to a shape of first material 933. In the back side view of FIG. 9B, a portion of antenna 930 may be positioned on a back surface 933b of material 933 to allow that portion of antenna 930 to be electrically coupled with chip 740 in a cavity 940, as depicted in FIG. 9C. The back surface 933b may include a groove, indentation, recess, depression, or the like, denoted as 933g, in which the portion of antenna 930 may be disposed in when positioned on the back surface 933b. 
Antenna 930 may include a structure 951 operative to receive the chip 750. Structure 951 may be formed from the same material as antenna 930 or may be made from a different material (e.g., an electrically insulating material) that is connected with antenna 930. Structure 951 may be operative to align chip 750 and antenna 930 with each other to facilitate electrical connection (e.g., via soldering, etc.) of electrically conductive nodes on chip 750 with electrically conductive nodes on antenna 930. For example, the nodes may comprise pads, bumps, balls, or other electrically conductive structures. Structure 951 may be configured to fit inside cavity 940 when antenna 930 is positioned on first material 933. In FIG. 9C, the cavity 720 through which plug 212 may be inserted 921 to mount the cap 904 to the band (102, 202, 702) may be configured to receive a plug, connector, or the like having a different configuration than plug 212, such as a male or female USB connector or plug for example. As one example, a male micro USB plug 912 may be inserted 921 into cavity 720 to mount the cap 904 to the band (102, 202, 702). First material 933 may be formed to include the cavity 720 having a shape configured to receive a profile of the plug 912. Suitable electrical connections with circuitry and systems in band (102, 202, 702) may be made by electrically coupling node 912c of plug 912 with the circuitry and/or systems using wire, PCB traces, busses, or other types of electrically conductive structures. Other types of plugs and/or connectors may be used and the foregoing are non-limiting examples.
Attention is now directed to FIG. 10A where a profile view of an antenna structure 930 for a wireless enabled cap 904 is depicted. Here, antenna 930 may be formed from a flexible electrically conductive substrate such as a flexible printed circuit board (FPCB), where all or a portion of the substrate may be electrically conductive. The substrate for antenna 930 may be cut, punched, sawed, cast or otherwise formed to the desired shape. As described above in reference to FIGS. 9B and 9C, a portion of antenna 930 (denoted as 1030 in FIG. 10A) may be positioned on a back surface 933b of material 933 and may include the cavity 940 and structures 951 for mounting or otherwise positioning the chip 750 relative to antenna 930 to facilitate electrical coupling between nodes on the chip and nodes on the antenna 930 (see FIG. 10B). Antenna 930 may include portions 1041 that are arcuate and/or include bends, folds, or non-planar shapes or contours, for example.
FIG. 10B depicts a cross-sectional profile view of the antenna structure 930 for a wireless enabled cap 904 and illustrates in greater detail the portion 1030 and its associated structure 951 and cavity 940 in which chip 750 is disposed. Structures 951 may be made from the same or different materials than antenna 930 and may be formed in a material of the antenna 930 or may be separately formed and mounted to the antenna 930 using adhesives, fasteners, glue, welds, etc., just to name a few.
FIG. 10C depicts a plurality of different views of an antenna structure 930 for a wireless enabled cap 904. The various shapes for antenna 930 may be formed by pressing, stamping, machining, rolling, vacuum forming, heating, or other machine processes. FIG. 10D depicts a plan view of an electrically conductive substrate that may be used as a starting material for an antenna structure 930 for a wireless enabled cap 904. Here, the starting material may comprise a substrate or sheet of an electrically conductive material (e.g., stainless steel or other metal and metal alloys) that is formed to a desired shape such as that depicted in the plan view of FIG. 10D, and then the above mentioned processes may be used to fashion the antenna 930 into its desired final shape. As describe above, first material 933 may serve as a mandrel or preform over which the antenna may be formed. In some examples, the starting material may not include the structures 951, and those structures may be later added as described above. In other examples, the starting material may not necessarily be an electrically conductive material or only portions of the starting material may be electrically conductive, such as the traces on a PCB or flexible PC board. The starting material may be an electrically non-conductive material or substrate (e.g., plastic, glass, dielectric material) upon which an electrically conductive material is applied or otherwise deposited or formed (e.g., via printing silk screening, screen printing, etc.) to create an electrically conductive medium for antenna 930, such as electrically conductive inks, paints, dyes, particles, graphene, nano-particles, for example.
Referring now to FIG. 11 where a profile view of a wireless enabled cap 704 including a RF isolation structure 1150 is depicted. Here, in example 1100, a RF isolation structure 1150 may be positioned in a cavity 1130 formed in a material 1131 of cap 704. The RF isolation structure 1150 may include a cavity 1120 formed therein and operative to receive at least a portion of the plug 212 or 912 by insertion 1121 of the plug into the cavity 1120, for example. For example, if plug 212 comprises a TRS, TRRS, a 2.5 mm audio plug or a 3.5 mm audio plug, then the cavity 1120, and optionally cavity 1130, may be sized accordingly to allow insertion of the plug 212. Similarly, cavity 1120, and optionally cavity 1130, may be sized accordingly to allow insertion of other types of plugs, such as the plug 912 (e.g., USB, micro USB, mini USB, Lightning® plug, RJ-45 plug, etc.), for example.
RF isolation structure 1150 may comprise a ferrite coil, a ferrite core, tape wound core, or other type of RF isolation devices (e.g., made from high magnetic permeability and low electrical conductivity materials) operative to isolate antenna 730 and/or improve RF performance of the antenna 930 and/or chip 750. In some examples, metallic structures (e.g., plugs 212, 912) or other structures in close proximity of antenna 730 may interfere with RF signal reception by antenna 730. For example, in FIG. 11, antenna 730, depicted in dashed line, may be positioned below (e.g., see 730 in FIGS. 8A and 8B) or embedded in a first material 1131 and/or embedded in a material 1135 (e.g., see embedded antennas 730, 730a, 730b in configurations 800c and 880d of FIG. 8C). An antenna 730c may be positioned on the material 1135 as depicted in example 1100a of FIG. 11. Antenna 730c may comprise an electrically conductive material connected with material 1135 or applied/deposited/formed on material 1135 (e.g., using a conductive ink or the like). RF isolation structure 1150 may isolate one or more antennas (e.g., 730, 730a, 730b) from other structures such as a second material 1135 that may be functional or non-functional, and/or the plug (212, 912), for example. Second material 1135 may be made from a different material than first material 1131. Second material 1135 may be electrically conductive or electrically non-conductive. As one example, the second material may comprise a plastic or other electrically non-conductive material and may be used for an esthetic purpose or include indicia, a logo, a trademark, artwork, instructions, an image, a name, initials, a nick name, a monogram, a model number, a serial number, etc., just to name a few. In other examples, second material may be selected to provide RF isolation of antenna 730. The cap 704 may have a different shape and/or configuration than depicted in the non-limiting example of FIG. 11. In other examples, structure 1135 may be made from a material suitable for embedding the antenna (e.g., antenna 730b) in the structure 1135 as depicted in example configuration 1100a. In FIGS. 8A-11, the cap 704 when mounted or otherwise connected with a device, such as band 702 (see FIG. 7A) for example, may wirelessly communicate (e.g., 126, 136) with other wireless devices, wireless client devices, smartphone, tablets, pads, wireless networks (e.g., WiFi, WiMAX, one or more varieties of IEEE 802.x, Bluetooth, Bluetooth Low Energy, NFC, or others, etc.).
Attention is now directed to FIG. 12 where examples 1200a-1200d depict an antenna 1230 that may be printed, deposited, screen printed, silk screened, or otherwise formed on an electrically non-conductive structure or surface, such as material 1235, for example, using an electrically conductive ink, paste, dye, plastic, or other suitable materials. In example 1200a, a surface 1235s of material 1235 may have a logo or other design formed on it using any number of processes, such as those described above. The logo antenna 1230 may be electrically coupled with chip 750 (not shown) using any suitable electrically conductive structure such as wire, conductive traces, etc. In example 1200b, material 1235 may be coupled (e.g., using glue, press fitting, adhesive, fastener, welding, etc.) with material 1231 to form cap 704, which may be operative to wirelessly communicate (126, 136) as described above.
In example 1200c, cap 704 may include the logo antenna 1230, another antenna 1230a, or both. Antenna 1230a may be a flexible PC board, or some other electrically conductive substrate that is electrically coupled with chip 750 (not shown) and positioned on a structure 1241, for example. Either one or both of the antennas 1230, 1230a, may be used for the aforementioned wireless communications (126, 136). In example 1200d, the components of example 1200c may be coupled to form cap 704. Other embedded and/or non-embedded antennas (not shown) may be included in the cap 704 depicted in examples 1200a-1200d, such as those depicted in FIGS. 8A-9C and 11, for example. Antenna 1230 need not be a logo and may comprise any form or design that may be printed or otherwise formed on material 1235. Antenna 1230 may comprise a plurality of separate antennas or discrete antennas that are formed on 1235, with each antenna electrically coupled with chip 750. In other examples, a sub-set of the plurality of separate antennas or discrete antennas that comprise 730 are electrically coupled with chip 750. The housing of the cap as described herein may be a body or other structure operative to be gripped by the fingers or digits of a user's hand to facilitate mounting and un-mounting of the cap from the plug (e.g., 212, 912) of the device (e.g., 702). The housing of the cap as described herein may include structures operative to facilitate gripping of the cap by the user, such as silicone, ridges, grooves, knurling, or other materials or structures that may provide grip, traction, etc.
