Abstract: The present disclosure provides a system and method using a charge collection antenna in a wearable device to collect charge variation based on a user's jawbone and muscle motion. The collected charge variation may be used to determine an on-body status of the wearable device. For example, in wireless earbuds, information acquired from a charge collection antenna may be used to determine whether the earbud is worn in-ear by the user. The collected charge variation may also be used to detect jaw motion by the user.

Abstract: The technology provides for a power line communication system capable of providing data from a first device to a second device over a power line. The first device may include a set of contacts and a second device may include a second set of contacts. The second set of contacts may be adapted to electronically engage with the first set of contacts of the first device to form at least a power and ground lines connection. Circuitry within the first device and the second device may include circuitry for providing data over the power line connection between the first device and the second device. The circuitry may comprise a power line, a ground line, a transmitter line carrying data signals, a capacitor coupling the transmitter line to the power line at a connection point, and a receiver comprising two field effect transistors.

Abstract: A cavity printed circuit board (PCB) that allows electronic components with different dimensions disposed therein is provided. A cavity with a desired dimension is formed in the cavity PCB where the electronic components may be mounted and soldered therein. The cavity formed in the cavity PCB may also provide additional flexibility regarding placements and locations where the electronic components may be disposed in the 3D vertical stacking and packaging of the IC devices so as to provide alternatives of using different types of wiring or interconnection structures or fine-pitch connection lines among the electronic components.

Abstract: The present disclosure provides systems and methods for activating a general purpose input/out (“GPIO”) pin. The system may include a control device, agency device, and a controlled device. The agency device may be part of the controlled device or it may be a separate device. The agency device may receive a communication signal transmitted from the control device. The agency device may count the number of pulses during a certain period of time to determine a GPIO pin to trigger on the controlled device.
