  • Patent number: 8378212
    Abstract: An electrical feed-through assembly and method of making an electrical feed-through assembly provide an electrical feed-through assembly that can survive exposure in a high pressure liquid, for example, seawater at least 9000 psi, for substantial periods of time, for example, twenty years, without substantial leakage of the high pressure liquid into or through the electrical feed-through assembly.

  • Patent number: 8071878
    Abstract: A display assembly for a portable terminal inhibits the penetration of foreign matter from an exterior environment into the interior of the portable terminal. The display assembly includes a display for mounting in an open-faced compartment enclosed by a bottom/top cover plate. A resilient seal component of the display assembly is positioned between the display and the compartment, the seal component including a body including a base portion connected to a top portion by side portions for defining an interior channel for engaging the sides of the display, once received therein. A top portion of the seal component is adapted for overlapping a portion of the top surface of the display and the base portion for overlapping at least a portion of the bottom surface of the display.

  • Patent number: 6570090
    Abstract: In order to be able to produce an electrically conductive, positive connection between an end electrode of a gas-filled discharge path and a lead more simply in fabrication-oriented terms, the raised terminal region, which is provided at the end electrode, is provided with a blind hole into which the one end of the lead is introduced and joined thereat to the terminal region with a laser welding.

  • Patent number: 6465729
    Abstract: A method for producing an electrical feedthru wherein a thin liquid conductive film is deposited into a shallow trough of an insulating machinable substrate. The conductive film and substrate are fired and then the resulting bound composite is ground flush with the adjacent surface of the insulating machinable substrate. The surface cohesion of the fired composite, and the resulting high quality surface finish of the grinding operation, combined with an elastomeric seal, create low leakage barriers capable of supporting a pressure differential while allowing isolated electrical conduction across a pressure or vacuum envelope. The method produces a space saving feedthru which allows a high signal line density in a limited space, is relatively simple to assemble, allows for disassembly rework, can be ‘designed into’ unique geometries of varied applications, and which has a single O-ring sealing across all traces.
