Patent Description:
This application is also related to <CIT>, to <CIT>, and to <CIT>.

Wearable devices can be generally characterized as body-worn and/or body-associated devices. Capacitive sensing approaches find use in wearable devices as a means of user input. Typically, a surface, such as an enclosure or housing, of the wearable device is made touch-sensitive via capacitive sensing for purposes of receiving user input.

The use of a large, touch-sensitive casing, however, minimizes the space available on the surface/exterior of the device to accommodate other aspects of device operation, such as, for example, an antenna. Antennas are a typical feature/requirement of wearable devices for wireless communication with external devices. While one solution could be to internalize the antenna into the body of the device, a conductive housing can substantially block/hinder the wireless signal from the antenna.

There is hence an unmet need to improve use of the conductive housing of a wearable device for different aspects of device operation.

<CIT> teachings involve an electronic device that may have electrical components such as sensors. A sensor may have sensor circuitry that gathers sensor data using a conductive structure. The sensor may be a touch sensor that uses the conductive structure to form a capacitive touch sensor electrode or may be a fingerprint sensor that uses the conductive structure with a fingerprint electrode array to handle fingerprint sensor signals. Near field communications circuitry may be included in an electronic device. When operated in a sensor mode, the sensor circuitry may use the conductive structure to gather a fingerprint or other sensor data. When operated in near field communications mode, the near field communications circuitry can use the conductive structure to transmit and receive capacitively coupled or inductively coupled near field communications signals. A fingerprint sensor may have optical structures that communicate with external equipment.

<CIT> discloses an adaptive band-pass filter for a wireless receiver that comprises a band-pass filter associated with the receiver, the band-pass filter configured to selectively filter the received signal, and a switch responsive to a control signal, the switch configured to control the band-pass filter based on a level of the received signal.

<CIT> discloses a processor-based personal electronic device (such as a smartphone) that is programmed to automatically respond to data sent by various sensors from which the user's activity may be inferred. One or more of the sensors may be worn by the user and remote from the device. A wireless communication link may be used by the device to obtain remote sensor data. Data from on-board sensors in the device - such as motion sensors, location sensors, and the like - may also be used to deduce the user's current activity.

<CIT> discloses a portable electronic device that includes a first housing, a second housing to the first housing, a circuit board, a display module, a touch panel, a near filed communication (NFC) module, and a NFC antenna. The circuit board, the display module, the touch panel, the NFC module and the NFC antenna are orderly mounted in a space between the first housing and the second housing. The NFC antenna is set around the touch panel or at one side of the touch panel or the NFC module.

In some embodiments, the housing can be operated in the first configuration by conductively coupling the housing to a capacitive touch circuit or a radio frequency (RF) transmission circuit and conductively isolating the housing from the other of the capacitive touch circuit or the RF circuit. In some embodiments, the housing can be operated in the second configuration by conductively coupling the housing to a capacitive touch circuit or a radio frequency (RF) transmission circuit and conductively isolating the housing from the other of the capacitive touch circuit or the RF circuit.

In some embodiments, the method <NUM> further includes transmitting via a communication channel (e.g., the communication link <NUM> in <FIG>), a first control signal to the second circuit to attain the first configuration, and transmitting, via the communication channel, a second control signal to the first circuit to attain the second configuration. In some embodiments, the communication channel includes the control circuit, and is formed between the first circuit and the second circuit.

In some embodiments, the control signal is a continuous signal and the operating the housing in the first configuration includes maintaining the first configuration for a duration of the first control signal. In some embodiments, the housing can be operated in the first configuration for a predetermined duration after a signal pulse is transmitted via the communication channel. The signal pulse is at least a part of the first control signal. In some embodiments, the housing can be operated in the first configuration until a second control signal is transmitted via the communication channel.

In some embodiments, the method also consists of receiving fitness data from one or more sensors. The fitness data is associated with a user.

In this manner, the conductive housing of a device can be configured for multiple purposes. Enabling different configurations for housing reduces form factor while optimizing the use of the housing.

The device <NUM>, or <NUM>, or <NUM>, or <NUM> can be in communication with other devices (not shown) via a communication link (not shown) and/or via a network. The communication link can be any suitable means for wireless communication between the devices and other devices, including capacitive, magnetic, optical, acoustic, and/or the like. The communication link can include bidirectional communication and, in some embodiments, any or all communications may be secured (e.g., encrypted) or unsecured, as suitable and as is known in the art.

In some embodiments, the device can be characterized as generally described in <CIT>. In some embodiments, the device is configured for proximity based data transfer of fitness data to another device, as disclosed in <CIT>. In some embodiments, the one or more housings described herein can be used to provide connectivity between a power source and one of the device components/ electronic circuits, as disclosed in <CIT>. In some embodiments, the portion of the housing configured for multiplex use can be different from the portion of the housing that provides connectivity with device components/electronic circuits as described in '<NUM> application.

Some embodiments described herein can relate to a kit including the device. In some embodiments, the kit can include one or more holders for the device. As an example, a kit can include the device, and further include one or more accessories for holding the device such as a necklace, a wrist strap, a belt, a clip, a clasp, and/or the like.

Some embodiments described herein relate to a computer storage product with a non-transitory computer-readable medium (also referred to as a non-transitory processor-readable medium) having instructions or computer code thereon for performing various computer-implemented operations. The computer-readable medium (or processor-readable medium) is non-transitory in the sense that it does not include transitory propagating signals (e.g., a propagating electromagnetic wave carrying information on a transmission medium such as space or a cable). The media and computer code (also referred to herein as code) may be those designed and constructed for the specific purpose or purposes. Examples of non-transitory computer-readable media include, but are not limited to: flash memory, magnetic storage media such as hard disks, optical storage media such as Compact Disc/Digital Video Discs (CD/DVDs). Compact Disc-Read Only Memories (CD-ROMs), magneto-optical storage media such as optical disks, carrier wave signal processing modules, and hardware devices that are specially configured to store and execute program code, such as Application-Specific Integrated Circuits (ASICs), Programmable Logic Devices (PLDs), Read-Only Memory (ROM) and Random-Access Memory (RAM) devices.

Examples of computer code include, but are not limited to, micro-code or micro-instructions, machine instructions, such as produced by a compiler, code used to produce a web service, and files containing higher-level instructions that are executed by a computer using an interpreter. For example, embodiments may be implemented using Java, C++, or other programming languages and/or other development tools.
