Abstract: An electrical connector in sheet form or the like which has a low through resistance in a volume between opposing surface contacts on opposite sides or surfaces of the sheet and provides a substantially higher isolation resistance in all volumes thereof between a contact on the surface of the sheet which is at a distance (isolation distance) greater than about the thickness of the sheet from any of the first of the above mentioned contacts. A circuit board or sheet of homogeneous material having one or more circuit elements adhering to a surface thereof, said sheet providing a low through resistance path between each circuit element and opposed and aligned contacts positioned in surface contact with the opposite side of the sheet while providing a high isolation resistance between out of alignment contacts positioned on the opposite side of the sheet and between contacts positioned on the same side of the sheet positioned an isolation distance from said circuit elements. The circuit board with a circuit pattern is shown in various applications, such as keyboard or watch.

Abstract: The treadle assembly of the present invention comprises one or more lightweight flexible circuits completely sealed within an envelope of resilient elastomeric material. This treadle is thus more resistant to water, wear, road salt, and other environmental factors than conventional treadle assemblies. 2214P

Abstract: TITLE: OVERVOLTAGE PROTECTION The overload protection material of this invention comprises a plastic preferably an elastomer, e.g. silicone rubber, homogeneously and highly loaded with silicon carbide particles (powder) and a lesser amount of a Group IV B element-carbide particles (powder). The material is preferably form stable and is placed (across) a semiconductor junction or between electrodes of a device to be protected so that when high voltage surges appear across the junction or device to be protected the material breaks down (conducts) before the junction or device is destroyed. The material is bidirectionally conductive in its voltage threshold characteristic and repeatedly recovers unlike a fuse so that it provides continuous high voltage over-voltage (e.g. surge) protection.
