Alternate methods include attaching non-conductive plates to the composite, forming pores within the pressure conduction composite, and inserting a temperature responsive material into a porous composite.Type: GrantFiled: January 26, 2005Date of Patent: July 4, 2006Assignee: QorTek, Inc.Inventors: Bruce Bower, Gareth Knowles

Patent number: 7069641Abstract: The present invention discloses a method for preparing a conductive polymeric composite material having carbon black utilized to a structure for composite materials of a positive temperature coefficient thermistor. The method first provides a metal laminated material comprising a top metal layer and a bottom metal layer, an insulating layer between the top and the bottom metal layer, and a conducting through hole disposed between the top metal layer and the bottom metal layer. A composite electroplating process is then performed to form an composite electroplating layer on the surface of the top metal layer, wherein the composite electroplating layer is a continuous porous structure with a secondary aggregation of carbon black and electroplated metal.Type: GrantFiled: April 25, 2003Date of Patent: July 4, 2006Assignee: Protectronics Technology CorporationInventors: Ren-Haur Hwang, Der-Yang Liu, Chen-Ron Lin

Patent number: 6900610Abstract: The invention is a system for controlling the position of a movable member moved by a prime mover by monitoring the position of the movable member; generating position information based upon this monitoring; and controlling the prime mover based upon the position information by providing a counter force to the movable member substantially equal to an opposing force opposing the movement of the movable member. The invention may include a movable member, such as a ram used for fastening a terminal to a wire; a spring; a DC planetary gear motor for providing a force to the movable member opposing the spring; a position detector, such as an linear voltage displacement transducer, to detect the position of the movable member and generate position information; and a controller, which may include a logic board or microprocessor and memory, for controlling the force from the motor in response to the position information.Type: GrantFiled: May 20, 2003Date of Patent: May 31, 2005Assignee: Tyco Electronics CorporationInventors: Gary L.
