Abstract: Capacitive sensing for device power management is described. In accordance with the described techniques, a device includes one or more capacitive sensors, and a sensor processor communicatively coupled to one or more capacitive sensors. The sensor processor receives a capacitance measurement from the one or more capacitive sensors, and controls power consumption of the device based on whether the capacitance measurement indicates that a human user is handling the device.

Abstract: A portable electronic device includes a status detector and a processor. The status detector is configured to obtain acceleration data from a motion sensor of the portable electronic device. The status detector is further configured to determine, for each acceleration measurement in the acceleration data, whether the acceleration measurement satisfies an acceleration threshold. Responsive to the acceleration measurement satisfying the acceleration threshold, the status detector is configured to increment a first counter. Responsive to the acceleration measurement not satisfying the acceleration threshold, the status detector is configured to selectively increment or refrain from incrementing a second counter. The status detector is further configured to determine whether the portable electronic device is in an on-table or an off-table state based on whichever of the counters reaches a counter threshold.
