  • Patent number: 7717749
    Abstract: A multiport connector which includes a housing having at least two aligned compartments, each compartment being structured and arranged to receive respective plugs. A multilayer printed wiring board separates the two compartments, the printed wiring board having circuit patterns on opposite sides of opposed non-conductive layers and a metal shielding layer intermediate the non-conductive layers. A first plurality of conductive contact fingers is disposed in one of the compartments, the first plurality of fingers having first portions for making electrical contact with one of the plugs and second portions for making contact with the circuit pattern on one of the non-conductive layers of the multilayer printed wiring board.

  • Patent number: 4070052
    Abstract: A resilient or shock-absorbing bumper for vehicle, which bumper is characterized by its simple, low cost and compact construction, and by being free of movable mechanical parts, and, consequently, which does not need any maintenance to preserve its operativeness. This resilient vehicle bumper includes an elongated rigid channel member of U-shape transverse cross-section defining an open side and an opposite side securable to a vehicle, an elongated rubber membrane mounted in the channel member, projecting from the open side thereof, and having transverse internal partitions dividing the membrane into a series of closed cells serially arranged along the channel member, and sand filling alternate cells, while the other cells are empty to allow lateral bulging of the sand-filled cells in the empty cells upon impact against the rubber membrane. Reinforcing bars are embedded longitudinally in the front portion of the rubber membrane.
