Patent ID: 8509755

Claim:
A method for controlling activation of a component on an electronic device, comprising: in a movement processing state, monitoring a motion detection circuit in the electronic device for a movement signal indicating a movement of the electronic device, analyzing the movement signal and if the movement signal matches a profile for an activation movement for the electronic device then activating the component on the electronic device; progressing to a lockstep state from the movement processing state when the movement signal does not match the profile within a timer condition; and in the lockstep state, initially operating the electronic device in a first power state where movement data relating to the movement signal is not provided to a microprocessor in the electronic device; and when the electronic device is expected to be monitoring for receipt of a synchronization signal from a communication network operating the electronic device in a higher power state compared to the first power state, monitoring for the movement signal, providing the movement data to the microprocessor, and when the synchronization signal has been received, placing the electronic device in a second power operating state consuming less power than the first power state.
