Abstract: A radio frequency attenuating connector includes a secondary coil (57) connected to a load (67a), an electromagnetic shield (61) enclosing the secondary coil and the load, a primary coil (55), a coupler (41) for detachably coupling the primary coil and the secondary coil, an integrated circuit (63) including a square wave oscillator producing complementary output signals, and first and second switching devices (105, 107). The first switching device (105) is responsive to one of the complementary output signals for causing a current to flow in one direction through at least a portion of the primary coil during a first half cycle of oscillation, and the second switching device (107) is responsive to another of the complementary output signals for causing a current to flow in an opposite direction through at least a portion of the primary coil. The integrated circuit has an enable feature and includes additional protection circuitry (91) for enhancing the safety of the radio frequency attenuating connector.

Abstract: An air bag initiator including a main body (2) and squib (3). The squib (3) includes a charge (7) mounted in a charge holder (5), a header (6) press fitted onto the charge holder (5) and a cup (4) welded to the header (6). The squib (3) also includes first and second lead pins and a bridgewire (10). A cap (11) snap fits onto the main body (2) and holds the squib (3) in place during subsequent assembly operations. Ferrite beads (12) for frequency attenuation and potting material are located in a cavity of main body (2). The first lead is mounted off center in a bore passing through the header (6) to allow bridgewires of different lengths to be used with the same header design. The cup (4) includes a depression to maintain a single explosive powder charge (7) under pressure and in contact with the bridgewire (10). An outer cup can be welded to the housing and an insulating cup can be provided between the cup of the squib (3) and the outer cup to provide enhanced hermetic sealing of the charge (7) and prevent current from passing between the cups.
