Abstract: An electrical connector system for providing low-loss, long-life electrical connection over many repeated coupling/uncoupling cycles. The connector utilizes ribbon contacts flexibly deformable in one axis to make electrical connection, substantially without sliding and compression friction during coupling and uncoupling. The connector comprises a receptacle and a plug, the plug housed within a shell. The plug is inserted almost fully into the receptacle before electrical or mechanical connection is made between corresponding contacts. A cam disposed in the shell flexes a contact mounting blade on the receptacle at the end of insertion, to bring the contact of the receptacle into electrical connection with the corresponding contact of the plug.

Abstract: A touch activated controller generates UP/DOWN control signals in response to movement of a human finger (or other comparable contact) along a control surface thereof. The UP information is derived from movement of the finger in one direction and the DOWN information is derived from movement in a substantially opposite direction. This system generates a sequence of control signals in one or the other of the two directions. In addition, when the finger is removed from the device the output remains in its last previous state or condition existing before removing the finger. Thus, the logic of the system is sensitive substantially to motion and direction of movement so that the logic of the operation of the device closely resembles the motion of a thumbwheel control. Merely placing a finger on the surface of thumbwheel or on the surface of the disclosed device generates no change in the position of the thumbwheel or the output of the device herein.
