Patent number: 9088109Abstract: An electrical connector assembly for suppressing a back electromotive force (“EMF”) spike originating from an electromagnetic device is provided. The electrical connector assembly includes a pin-side electrical connector coupled to the electromagnetic device. In one example, the pin-side electrical connector has a diode opening surrounded by an insulating material. The electrical connector assembly further includes a socket-side electrical connector for mechanically mating with and electrically coupling to the pin-side electrical connector. The socket-side electrical connector includes a suppression diode for suppressing the back EMF spike from the electromagnetic device. The suppression diode is positioned within the diode opening when the socket-side electrical connector is mechanically mated with and electrically coupled to the pin-side electrical connector.Type: GrantFiled: April 29, 2013Date of Patent: July 21, 2015Assignee: CURTISS-WRIGHT FLOW CONTROL SERVICE CORPORATIONInventors: David Lynn Little, Gary Joseph Elam

Patent number: 9028273Abstract: An electrical connector assembly for providing an environmental shield includes a bushing adapter configured to sealingly engage a bushing assembly accommodating a first electrical conductor. The bushing adapter further includes a first bore extending longitudinally therethrough to receive the first electrical conductor. An end fitting includes a second bore extending longitudinally therethrough to receive a second electrical conductor, and the end fitting is configured to sealingly engage the bushing adapter such that the first and second bores cooperate to define a main bore. A flowable dielectric material occupies substantially all empty space within the main bore, and at least one fill hole is in fluid communication with the main bore and configured to receive the flowable dielectric material. A method of assembling the electrical connector assembly is also provided.Type: GrantFiled: June 24, 2013Date of Patent: May 12, 2015Assignee: Curtiss-Wright Flow Control Service CorporationInventors: Alan Stephen Smith, Gary Joseph Elam

Patent number: 8574007Abstract: An electrical connector assembly is provided having an electromagnetic interference shield. The electrical connector assembly includes a backshell having a backshell bore and a shielding ferrule positioned within the backshell bore to provide an electromagnetic interference shield. The shielding ferrule includes an outer ferrule portion arranged circumferentially around an internal ferrule bore, and a shielding adapter received within the backshell bore of the backshell. The shielding adapter includes a cable extending longitudinally through the shielding adapter and the internal ferrule bore, the shielding adapter engaging the shielding ferrule such that axial movement of the shielding adapter towards the shielding ferrule radially compresses the shielding ferrule onto the cable. The shielding ferrule provides a substantially 360° electromagnetic interference shield around the cable.Type: GrantFiled: April 6, 2012Date of Patent: November 5, 2013Assignee: Curtiss-Wright Flow Control Service CorporationInventors: Alan Stephen Smith, Gary Joseph Elam

Publication number: 20070279276Abstract: System for dynamically tracking a position of a target with an antenna in a communication system. The system includes an antenna system (410) configured for generating a sum and difference antenna pattern (201-1, 201-2). A sum RF channel (401) is coupled to a sum channel output of the antenna system. A difference RF channel (402) is coupled to a difference channel output of the antenna system. An RF coupler (422-1) is provided that has a first input coupled to the sum RF channel and a second input coupled to the RF difference channel. One or more coupling control devices (418-1, 418-2) selectively vary an effective coupling value as between the difference channel and the sum channel. An antenna tracking error signal is generated at an output of the coupler.Type: ApplicationFiled: May 31, 2006Publication date: December 6, 2007Applicant: HARRIS CORPORATIONInventors: James K. Conn, James B. Offner, Larry P. Serulneck, Earl B. Knick, Ron Hash, Ying-Ming Lee, Pete Denney, Joseph A. Elam, Brian A. Smith

Patent number: 6856216Abstract: A phase shift control voltage distribution scheme for a phased array utilizing voltage-proportional phase shift devices employs a digital-to-analog converter that supplies respectively different analog voltages to a sample-and-hold switch network coupled to analog voltage control inputs of the plurality of voltage-proportional phase shift devices. In order to impart a phase shift control voltage to one or more phase shift elements of the array, a control unit supplies a prescribed combination of a digital control code to the digital-to-analog converter and a switch control code to sample-and-hold switches of the switch network.Type: GrantFiled: October 6, 2003Date of Patent: February 15, 2005Assignee: Harris CorporationInventors: Ralph Trosa, Robert W.
