    Abstract: USB ports such as Type-C USB-C ports in a personal computer (PC) or other computing device may be configured in dual-role port (DRP) mode. The DRP mode may provide the ability for a port to switch between providing power to an external device and receiving power from an external power source to the into the computing device. The voltage level received from an external power source is typically higher than the voltage level provided to an external device. When a USB device fails, it may apply the higher voltage level to an external device, which may cause the external device to fail. A voltage sense and device detection circuit which may be used to detect an internal failure and prevent a higher internal voltage to be applied to a USB device.

    Abstract: Techniques for wireless audio device selection are disclosed. In the illustrative embodiment, a compute device uses visual training to recognize headphones worn by a user. When the user puts on the headphones, the compute device may recognize the headphones and automatically route audio output to the headphones. In some embodiments, when selecting from several possible wireless audio output devices, the compute device may determine a distance to each of the wireless audio output devices and select one of the wireless audio output devices based on the distance to the wireless audio output device.

    Abstract: Systems, apparatuses and methods may provide for power adapter technology that includes an adapter plug having a housing, a plurality of contacts positioned within the housing, wherein the plurality of contacts includes one or more configuration channel contacts, and a piezoelectric membrane positioned on an external surface of the housing, wherein the piezoelectric membrane is electrically connected to the one or more configuration channel contacts. Additionally, sink device technology may detect a signal from the piezoelectric membrane of the adapter plug via the configuration channel contact(s), wherein the signal indicates user contact with the adapter plug, and disconnect a bulk capacitor from a receptacle adjacent to the adapter plug in response to a disconnect condition associated with the user contact.

    Abstract: An interface card includes a circuit board, a device mounted on the circuit board, and a PMIC mounted on the circuit board. The PMIC includes a PMIC processor communicatively coupled to a host processor of a host system. The PMIC processor is configured to receive an input voltage signal from a power supply that is external to the interface card. The PMIC processor generates at least one output voltage signal based on the input voltage signal. The at least one output voltage signal is supplied to the device. A power enable signal originating from the host processor is detected. The power enable signal is detected at a GPIO connector of the PMIC. The PMIC processor deactivates generation of the at least one output voltage signal based on the power enable signal.
