A wireless telephony system comprising a base station and at least one portable device. The base station employs a ratio frequency (RF) receiver and an optical transmitter. The portable device employs an optical receiver and an RF transmitter.

Hybrid telephony communication system

A miniature electro-mechanical transducer uses a body of elastomeric material composed of alternate layers of flexible dielectric material and flexible conductive material. The ends of the layers form opposite surfaces. An actuating member moves against one surface and the other surface contacts two spaced electrodes. The arrangement is such that a progressively increasing number of layers of conductive material are brought into an electrically parallel circuit between the electrodes.
