A voice bus on a computer backplane provides point-to-point connection between a plurality of slots on the backplane to a particular slot. Connection from the plurality of slots is provided by third connectors which lie between first and second connectors defining the slots. Connection to the particular slot is via its respective second connector. In particular, the computer backplane is physically and electrically compatible with the IEEE standard 1014-1987 defining the VMEbus. The presence of the third connector is compatible with the VMEbus standard both electrically and physically.

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.
