Abstract
A system for locating an object, particularly a remote control, has a transmitter and a receiver, wherein the receiver has circuitry implementing power saving features. The receiver includes circuitry for turning off portions of the circuitry not essential for performing the current task. The receiver additionally only activates the wireless signal receiver portion of the circuitry periodically for short periods of time. The time of activation represents a small fraction of the operational time if the wireless signal receiver portion were to remain activated continuously.
