Abstract: A insulation displacement connector (IDC) patch panel includes a circuit (PC) board with interdigitated capacitance for balancing out inherent capacitance found within IDCs of the panel. Unwanted cross-talk signals are reduced as a consequence.

Abstract: A connector jack having a body with a receptacle to receive a plug, a circuit board, and contact tines extending within the receptacle. Each tine has an end attached to the circuit board and a free end, and is moved in response to contact by a corresponding one of the plug contacts in a first direction as the plug is inserted into the receptacle. The jack includes resilient spring members extending within the receptacle, each positioned adjacent to a corresponding one of the tines to be engaged thereby when moved in the direction by the corresponding plug contact as the plug is inserted into the receptacle, and apply a supplemental force to increase contact force and tine resiliency. A tine contact portion has a pair of lateral members that receive a spring engagement portion therebetween and has a recess in which the spring engagement portion is positioned.

The jack also includes a plurality of resilient spring members extending within the receptacle, each positioned adjacent to a corresponding one of the tines to be engaged thereby when moved in the first direction by the corresponding plug contact as the plug is inserted into the receptacle, and apply a supplemental force thereon to increase contact force and tine resiliency.

Abstract: A compensating jack connector includes a printed circuit (PC) board with wire trace layers for reducing unwanted crosstalk originating in wire pairs including those found within a conventional communication plug coupled to the compensating jack connector. Some embodiments of the PC board of the compensating jack connector include layers having inter-digitated capacitance to form compensative capacitive coupling and multi-point compensative coupling and inductance to form inductive coupling to reduce the unwanted crosstalk. Pairs of wire traces are so oriented in some of the PC board layers to couple inductance between one pair of wire traces with inductance between another pair of wire traces to contribute in reduction of unwanted crosstalk. Some embodiments of multi-point compensative coupling position inter-digitated capacitance at different time delay distances from origination points of unwanted crosstalk and having different polarities to contribute in reduction of unwanted crosstalk.

Abstract: A modular higher density communications coupling system including a universal platform for supporting multiple connectors from a single outlet hole is disclosed. The platform includes a main body member having a registration ridge extending forward of the main body member for extending into a standard sized outlet hole. A pair of apertures adjacent to each other extend through the main body member and are generally surrounded by the registration ridge. A pair of connector housings are attachable to the rear of the platform in alignment with the apertures for housing connectors. A pair of retaining members on two sides of the apertures hold the connector housings in position. A pair of support members extend rearwardly from the main body of the platform on the other two sides of the apertures. A termination plate is mounted in the support members, the termination plate having a plurality of electrical couplings for connecting the wire from a wall to the connector.

Abstract: Easily removable conformable coatings having a controlled thickness with a predetermined minimum value are obtained by the application of a composition comprising a mixture of a viscous carrier material and small particles of a second material by any known method. When both the carrier material and the particulate material mixed therewith are selected to have high dielectric constants, the mixture may be used to obtain coatings suitable for protection of circuit boards supporting high impedance electrical circuits. A mixture of a commercially available grease, e.g., Amoco RYKON (TM), with glass microspheres comprising up to 50% of the volume and preferably in the size range 3-5 mils, provides excellent dielectric conformal coatings for high impedance circuit boards. By contrast, by selecting both the viscous carrier material and the particulate matter mixed therein to have high conductivity, electrically conductive coatings for particularized users may likewise be obtained according to this invention.

Abstract: In a temperature measurement system using a thermocouple connected to a pair of circuit wires coupled to a voltmeter for providing an output reading, an isothermal block (48) formed of alumina ceramic contains a series of openings (58-66) in linear juxtaposition. Metal connectors (68) located in two of the openings to interconnect the thermocouple and printed circuit wires of a circuit board (52) establish a reference junction. A temperature sensor (50), preferably a transistor, in a third opening measures the temperature of the isothermal block (48) to compensate the output reading for error created by the reference junction. The connectors (68) are in resilient contact with the interior wall of the isothermal block (48) to maintain good heat conductivity between the connectors and the temperature sensor (50). Portions of the connectors (68) extending outside the isothermal block (48) retain the isothermal block (48) to the circuit board (52).
