Abstract: An improved connector for terminating flexible parallel conductors in which a male part has a length of distal surface about which an end of a flexible group of parallel conductors is bent. The male part, with the group of parallel conductors bent thereabout is inserted into a female part having a closed slot therein and a plurality of contacts along one of the walls thereof. Upon mating of the two connector parts, the contacts of the female part electrically engages respective ones of the parallel conductors. Various means are provided for keeping the conductors aligned during the mating action and latch members on both male and female parts cooperate to releasably secure the two parts together.

Abstract: A variable capacitance dual pressure sensor for sensing the pressure levels of a pair of fluids independently comprises an enclosure having a top wall and a bottom wall, and a substrate of dielectric material having a first major surface facing the top wall and a second major surface facing the bottom wall. A first electrode is affixed to a portion of the first major surface and a second electrode is affixed to a portion of the second major surface. A first flexible electrically conductive diaphragm is sealed to the first major surface of the substrate and is spaced from the first electrode to form therewith the plates of a first capacitor and a second flexible electrically conductive diaphragm is sealed to the second major surface of the substrate and is spaced from the second electrode to form therewith the plates of a second capacitor. The first and second diaphragms are electrically coupled together to form a common connection.

Abstract: A capacitance-to-voltage transformation circuit for providing an output voltage proportional to capacitive variations includes a variable capacitor, a reference voltage source, and circuit means for charging the variable capacitor to the reference potential. A switch means alternately connects the variable capacitor to the charging means and to ground at a cyclical rate determined by an oscillator clock. An impedance means coupled between the charging and switch means, develops a voltage drop thereacross of a magnitude directly proportional to capacitance variations of the variable capacitor.In accordance with another aspect of the invention, the circuit includes a compensating means for nullifying any fixed capacitance component of the variable capacitor.
