Remote control electrical device

Abstract

Abstract A remote control transmitter (3), which can be switched at a push button (4) and is held in the hand (2) of a user, of the remote control of an electric apparatus (1) generates radiation fields (5, 6) of differently identified carrier waves (7, 8) of different direction. The received field strength of the carrier waves (7, 8) received at a receiving element (14) of the remote control device are measured and from these control signals are formed in a direction detector which identify the angular deviation (Alpha) of the pointer direction (9) of the remote control transmitter (3) from a direction (13) on an optically visible marking element (12) and by this means call up operating commands for controlling the electrical apparatus (1) from a command memory via a command selector. In this manner, an electrical apparatus can be remotely controlled with great variety of operations by means of certain rotational movements of a remote control transmitter directed towards the electrical apparatus from the wrist without observation of the remote control transmitter exclusively by observing the remote-controllable electrical apparatus or a display (11) of this apparatus. <IMAGE>
