Abstract:
Sensing circuitry of a first electronic device can be configured to sense a signal transmitted by the second, external electronic device contacting and coupling through the body of the user. The first electronic device can be configured to detect the contact while receiving data from the second device, and determine whether the signal transmitted by the external device corresponds an “intentional touch,” or corresponds to a signal coupling between a different body part and the external device or through a different signal pathway (e.g., electromagnetically, through the air, etc.).
Abstract:
A personal electronic device can include a main printed circuit board having disposed thereon a processing unit, one or more auxiliary circuits coupled to the main printed circuit board by one or more corresponding flexible printed circuits and one or more temperature sensors disposed on one of the flexible printed circuits. A processing unit of the portable electronic device can be configured to monitor the one or more temperature sensors, provide a warning in response to a monitored temperature exceeding a first threshold, and to cause a shutdown of at least a portion of the personal electronic device in response to the monitored temperature exceeding a second threshold. The temperature sensors can be negative temperature coefficient resistors.
Abstract:
A first device such as a wristwatch may include a front face at which a display is disposed and a rear face at which a rear housing wall is mounted. Antenna structures may overlap the rear housing wall and may be operable to transmit and receive relatively high frequency signals through the rear housing wall to a communication with a second device such as a wireless power transmitting device for the wristwatch. The second device may also include antenna structures that overlap a top surface housing. Respective sets of magnetic structures may be provided in the first and second devices to align the two devices and to form a reliable wireless communication link between the two devices. The first and second devices may include respective antenna arrays that include pairs of antenna elements that are selectively used to form a reliable wireless communication link.
Abstract:
Methods and systems for facilitating health research by utilizing one or more wearable sensor devices with a research mode are provided herein. Systems include a wearable sensor device that can pair with a first portable computing device of a user and a second computing device of a researcher in a first and second pairing, respectively. The wearable sensor device obtains one or more health parameters of a user. In one aspect, the wearable sensor device communicates research related and non-research related health information to the first computing device via the first pairing link and communicates only research related health information to the second computing device via the second pairing link. Methods for pairing one or more wearable sensor devices with one or more research computing devices and switching between operating modes to provide additional research related features are also provided.

Abstract:
Systems, methods, and devices are provided to sense unauthorized use of a vehicle. For example, an electronic device may include sensors to detect an operational parameter of a bicycle and communications circuitry to couple the electronic device to a second electronic device associated with user of the bicycle according to authorization information. Control circuitry may determine when the bicycle is in operation based at least in part on the detected operational parameter, identify whether the second electronic device is substantially within a communicative proximity of the electronic device when the bicycle is in operation, and generate an alert indicating unauthorized operation when the second electronic device is not identified as substantially within the communicative proximity of the electronic device.

An electronic device can include a housing, a back cover, a structural member, and a sensing circuit. The housing can at least partially define an internal volume of the electronic device and the back cover can define at least a portion of the internal volume and be connected to the housing. The structural member can be disposed against the back cover and at least partially within the internal volume, the structural member including an electronic component. The sensing circuit can be disposed in the internal volume and electrically coupled to the electronic component. The sensing circuit can detect an amount of charge of the electronic component as part of a user proximity sensor of the electronic device.
