Abstract: An ignition circuit (200) includes: an igniter (210) having first (211) and second (212) terminals; a first diode (225) electrically connected in series with the igniter at the first terminal; a second diode (230) electrically connected in series with the igniter at the second terminal. The first and second diodes each have an anode terminal (226, 231) and a cathode terminal (227, 232), wherein like terminals of the first and second diodes are electrically connected to the igniter, thereby defining proximal terminals and distal terminals. A capacitor (235) is electrically connected across the distal terminals and connectable in parallel with a series-connected energy source (215) and switch (220). The energy source and a switch are electrically connectable across the distal terminals via test lead wires. Current flow through the igniter sufficient to ignite the igniter is prevented until an ignition voltage is applied to the distal terminals that is equal to or greater than the reverse breakdown voltage of the first diode or the second diode.

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.

Abstract: The invention relates to a device for triggering an airbag comprising a control device, a triggering means for triggering the airbag and comprising electric lines that connect the control device to the triggering means, whereby a coil for attenuating high-frequency interference currents is connected in the electric lines which, in turn, induces interference currents into the electric lines as a result of an external magnetic alternating field. In order to attenuate the induced interference currents resulting from an external magnetic alternating field of the coil, a compensating coil is connected in the electric lines and is arranged in the surrounding area of the coil in such a way that the amount of current induced in the compensating coil is equal to that of the interference current induced in the coil by the external field, and both interference currents cancel one another out.

Abstract: A time delay gas generator for missiles, characterized by very long shelf life and accurately-determined time delay. Time delay powder (42, 43, 44) is layered at high pressure, and causes heating of a metal disc (51) at the end of a time delay interval that is accurately known. Such heating ignites an output charge (51) to generate gas, the gas breaking a closure (52) and performing a function in the missile.
