Patent number: 7618588Abstract: An integrate device includes a heater thermally coupled to a plurality of flow-through tubes to perform thermally-driven chemical reactions. A wire mesh heater is wrapped around each of multiple flow-through tubes, thereby creating a thermal interface between the mesh and the tubes. Each end of the wire mesh is coupled to an electrical contact. The electrical contacts are preferable positioned at an exterior portion of the integrated device to be easily placed in electrical contact with a voltage source. As current passes through the mesh, heat is produced. The heat passes from the mesh to each of the flow-through tubes via the thermal interface. The flow-through tubes can be fluidically coupled to a sample preparation module. The sample preparation module, the flow-through tubes, and the heater can be integrated within a single integrated device that provides automated sample preparation and thermally-driven chemical reactions for a variety of applications.Type: GrantFiled: August 10, 2005Date of Patent: November 17, 2009Assignee: Microfluidic Systems, Inc.Inventors: Chun-Wah (Phil) Lin, Bob Yuan

Patent number: 7607206Abstract: A monolithic, multi-layer heating element forms the high temperature tip of a glow plug assembly. The heating element includes a conductive core which is surrounded by an insulator layer, which in turn supports a resistive layer. An optional conductive jacket can surround the resistive layer. These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die, where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element. The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass. Various finishing operations may be required, following which the heating element is assembled to form a glow plug.Type: GrantFiled: December 29, 2005Date of Patent: October 27, 2009Assignee: Federal Mogul World Wide, Inc.Inventors: William J. Walker, Jr., John W. Hoffman, Jim May
