Abstract
A pair of transducer units and a transmission line extend the operational range of an infrared remote control device that normally operates electrical or electromechanical apparatus such as a television channel selector. One transducer converts electrical signals into an infrared radiation pattern and is located adjacent the apparatus. The other transducer is located at any desired remote location linked by wire to the first transducer, and converts into electrical signals the infrared radiation pattern produced by the infrared remote control device. The first transducer includes an emitter in the form of an infrared light emitting diode, and the second transducer includes a sensor in the form of a photo diode. In certain applications, the transducers utilize the existing television cable.
