Patent ID: 7786623

Claim:
A cordless electronic device with power management, comprising: an outer surface; a power consumption circuit operable to consume power and for use in the cordless electronic device; a power supply circuit operable to regulate the power from a power source used to power the power consumption circuit; a power control circuit operable to receive an input signal and to place the power consumption circuit in a lower or higher power state upon receipt of the input signal; a presence sensor operable to detect the presence of a user and to provide a presence sensor input signal to the power control circuit to place the power consumption circuit in the higher power state upon detection of the presence of the user; and a motion sensor operable to detect motion of the cordless electronic device, and to provide a motion sensor input signal to the power control circuit to place the power consumption circuit in the higher power state upon the motion detection, wherein the motion sensor is configured to provide the motion sensor input signal to the power control circuit only if the presence sensor detects the user touching the outer surface.
