METHOD AND APPARATUS FOR STAGED APPROACH TRANSIENT RF DETECTION AND SENSOR POWER SAVING

摘要

A method includes receiving a first signal from an antenna of a device and at least one internal device signal in a low-energy consumption path, detecting a peak in at least one of the first signal and the at least one internal device signal, and activating a higher energy consumption path to analyze the first signal when the detected peak is not in one of the at least one internal device signal.
