System and method for activating an electronic device

摘要

The invention provides a system and method for activating an electronic device from a low power state. In the system, an activation circuit for an electronic device is provided. The circuit comprises: a motion sensor circuit; an input device; and a monitoring circuit connected to the input device. The monitoring circuit provides power to the input device when the motion sensor circuit detects a notable movement of the device and selectively generates an activation signal used to activate the electronic device to a higher power state in response to receiving a notable signal received from the input device.
