An electronic packaging system for a digital data processing system is disclosed. The packaging system includes a multi-layer printed circuit mother-board having a plurality of double-ended pass-through electrical male contacts arranged in a plurality of similar patterns. The patterns of male contacts conform to and mate in electrical contact with the pattern of electrical female contacts of an electrical connector assembly. The electrical connector assembly is comprised of an insulative connect...

An electrically alterable, non-volatile interconnect selectively connects and disconnects microcircuit elements formed on a wafer. The interconnect is formed on the same wafer as the microcircuit elements during the circuit fabrication process to permit electrically controlled reconfiguration of the microcircuit elements on the wafer. This enables wafer scale integration by permitting defective circuit elements to be bypassed and operable, redundant circuits to be substituted for them. MNOS memo...

Circuitry for interconnecting a radio transceiver to a telephone line is disclosed. The circuitry provides controlled access to the telephone system lines from remote radio transceivers by way of a base transmitter-receiver unit which is connected through an impedance matching network to the telephone line. A carrier operated relay responsive to the base receiver unit controls access to the telephone line by means of a time delay relay whereby signals received by the base station are connected t...

An interconnection system for interconnecting a plurality of photovoltaic devices. The photovoltaic devices each have a first and a second side and the interconnect system is located on the second side of the photovoltaic devices. A sheet of dielectric material and a sheet of electrically conductive material are bonded together and positioned so that the dielectric material is next to the photovoltaic devices. A plurality of patterns are formed in the sheet of electrically conductive material. T...

A mounting bracket is carried by an end flange of a first electrical connector and includes projections which slidably engage grooves in a second electrical connector which is supported by the bracket. A hood covers the rear end of the first connector and at least partially covers and embraces the second connector supported by the bracket and includes an internal lateral projection which engages a hook-shaped portion of the bracket. The contact capacity of the first connector is greater than tha...

The electric plug of the present invention including a base plate, a yoke, a case movable over said yoke and a pair of flat contact pins of American type and also a pair of round pins of European type. The flat contact pins are fixed in the base plate of the plug, while the round contact pins are located in that part of the plug consisting essentially of yoke and case. When the case is drawn upwardly over the yoke, the two components can be tilted as a unit about journals in the base plate so as...

Described herein is a system for automatically providing interconnections among a plurality of telephone lines serving a subscriber station all under the control of a remote caller. An incoming call to the system is automatically answered, and the incoming line is then connected to an outgoing line either immediately or in response to tone or pulse dialing signals dialed in by the caller. Upon receipt of dial tone on the outgoing line the caller can dial out a call thereon directly from his remo...

In the fabrication of integrated circuits, step or ridge peak problems in forming via openings through sputtered quartz coatings to underlying metallization are minimized by subdividing the contact portions thereof into a plurality of adjacent line segments, and forming the via opening between the elevations or peaks on the line segments to expose portions thereof for interconnection by higher metallization levels.

A circuit board with connectors along more than one side designed to be stacked with similar boards, having a plurality of electrical contacts to connect to a connector header with resilient contacts, applying a force to the circuit board which is inclined from a central axis whereby the circuit board and the connector header join a tight, reliable compression contact.

Cross connect system for communications conductors comprises a cable connector which is mated with a cross connection connector. The cable connector has double ended terminals extending therethrough which have wire receiving portions on one end and receptacle portions on their other end. The conductors of the cables are electrically connected to the wire receiving portions of the terminals and the receptacle portions of the terminals are in alignment with cavities which extend through the cross ...
