  • Publication number: 20120048612
    Abstract: A composite gasket for sealing and EMI shielding is provided. The gasket has a resilient conductive mesh sheet embedded with an elastomer gel layer. The conductive mesh is corrugated to provide a series of repeating waveforms, providing the gasket with a lower deflection force, better corrosion resistance, and a higher EMI shielding capability. A second elastomer can be used around the edge portions of the gasket for improved abrasion resistance and increased tensile strength. A fiberglass sheet can be incorporated in the mesh for added reinforcement and support. The gaskets of the invention can be used on external aircraft components, such as external aircraft antenna mounts.

  • Patent number: 8114204
    Abstract: The present invention provides a system and method for transmitting information between a device within a housing to a second device, preferably a test or monitoring unit, outside of the housing. There are numerous issues associated with transferring information from within a sealed housing to an external device. In some cases, the use of wires inside the housing may be impractical, due to internal conditions, such as fluid flow, pressure or temperature. In one embodiment, the antenna of the external RF reading device is electrically connected to the dome of the housing. In another embodiment, the device within the housing is electrically connected to a housing component. In another embodiment, the gasket is used to pass information from within the housing to an external device.

  • Patent number: 7791902
    Abstract: A system for protecting electronic components to be disposed inside a computer housing comprising a gliding connector aligner for disposing inside the housing. The aligner has a central flat surface to be disposed over electronic components and a plurality of appendages with at least one nub each disposed at an opposing end to that of the central surface. The appendages are substantially perpendicular to the flat surface. An EMC gasket is also provided around the housing. The gasket in one embodiment has a plurality of portions with each portion having a central support line from which a plurality of complementary spring fingers emanates. The portions are connected to one another via a tab such that said gasket can be stretched around all housing corners such that said spring fingers from different portions are placed in a substantially perpendicular direction to one another.

    Abstract: A gasket for an electronic device for providing shielding against electromagnetic interference. The gasket is intended to be mounted between a first structural part and a second structural part of the electronic device. The gasket comprises conductive sealant paste and a carrier structure on which the sealant paste rests. The conductive sealant paste rests on the carrier structure as sealant paste areas such that the sealant paste areas are at apertures comprised by the carrier structure that perforate the carrier structure, being supported on the carrier structure and thus generating galvanic connections through said sealant paste areas at the apertures perforating the carrier structure from a first side of the carrier structure to a second side of the carrier structure.
