摘要： According to various implementations, a vehicle pyrotechnic initiator assembly includes an initiator that includes at least one electrode pin and a validation device in electrical communication with the at least one electrode pin. The validation device provides validation information about at least a portion of the initiator assembly and/or a safety device in which the initiator assembly is installed. The validation information may include a date associated with an expiration of the initiator assembly and/or the safety device. The validation information may also or alternatively include a manufacturer identity associated with a manufacturer of the initiator assembly and/or safety device. In some implementations, the validation device includes an electrical circuit and/or memory that stores the validation information. For example, the validation device may include an ASIC chip.

摘要： An initiator including a housing adapted to be received in an igniter or rocket motor, at least one charge at a distal end of the housing, an electro-explosive device behind the charge for detonating the charge when subject to a voltage HV, and a pressure bulkhead behind the electro-explosive device. An electronic subsystem in the housing is connected to the electro-explosive device through the bulkhead and includes a lead for providing the voltage HV to the electro-explosive device to initiate it, and a switch in the lead which does not conduct if errant voltages are present on the lead to prevent initiation of the electro-explosive device until the correct voltage HV is present.

摘要： A pressure switch is provided to arm a munition's fuze mechanism upon launch. The switch operation is based upon extreme gas pressures experienced during launch of the munition. The switch includes a piston contained in a housing. The piston translates due to launch pressures. The piston translation then causes a copper puck component to contact nearby electrical stab pins, to close a circuit. The closed circuit is then used to electrically arm the fuze mechanism.

摘要： Provided among other things are reactive energetic material systems used for conductors in detonators for increased efficiencies. According to an embodiment, a detonator may include: a conductor including at least two constituents including (i) an electrically conductive constituent, and (ii) an electrically non-conductive constituent, that when subjected to sufficient electrical energy, result in an exothermic reaction; and a flyer plate having a non-conductive surface in contact with said conductor. When the sufficient electrical energy is supplied to said conductor, rapid heating and vaporization of at least a portion of the conductor occurs so as to explosively drive at least a portion of the flyer plate away from said conductor. In an embodiment, a multilayer conductor may be formed of alternating layers of at least one electrically conductive layer, and at least one electrically non-conductive layer, that when subjected to sufficient electrical energy, result in an exothermic reaction.

摘要： A remote pyrotechnic ignition system includes a power supply for producing an electrical current in a transmitting induction coil to induce an electrical current in a receiving induction coil for igniting a pyrotechnic device. Thus, a wireless ignition communication section allows pyrotechnic mortars to be reused and substantially reduces set-up time by eliminating the wiring of fireworks normally required for a pyrotechnic production. Optionally, a capacitor is charged by the power source via a charging circuit and discharged via a firing circuit to produce the electric current in the transmitting coil in a pulse. The capacitor provides a two-stage firing safety feature. An electronic control device such as a circuit board may be mounted on the pyrotechnic device for controlling ignition of the pyrotechnic device and is especially useful in controlling ignition sequencing and overall ignition timing of a lift charge and burst charge of the pyrotechnic device.

摘要： An ignition circuit for a detonator is disclosed. The circuit includes; an igniter having a first terminal and an opposing second terminal, a first diode electrically connected in series with the igniter at the first terminal, and a second diode electrically connected in series with the igniter at the second terminal. The first and second diodes each have an anode terminal and a cathode terminal, wherein like terminals of the first and second diodes are electrically connected to the igniter, thereby defining proximal terminals proximate the igniter and distal terminals on an opposing side of each respective diode. An energy source and a switch are electrically connected in series with each other, and are electrically connected across the distal terminals. 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.

摘要： A pretensioner for a vehicle occupant safety restraint has an outer casing that contains a gas generant. An igniter has igniter material disposed within an igniter housing. A pair of electrodes are connected to the igniter material. A grounding path connector link electrically connects the igniter housing to a grounding path. The connector link may be formed by springs connecting the outer case to the grounding electrode and an interference fit connecting the igniter housing to the outer case. The link forms a low resistance path to short circuit undesirable static charges in the unit that would otherwise tend to cause unintentional activation of the pretensioner.

摘要： An electro-explosive device has two serpentine resistors fabricated on a thermally conductive substrate with the resistors being interconnected by a central bridge element. The resistance of the bridge element is much lower than that of the serpentine resistors and the serpentine resistors have a much larger surface area to volume ratio. A layer of zirconium is placed on the bridge element and explodes into a plasma along with the bridge element in order to ignite a pyrotechnic compound. The resistance of the bridge element increases with temperature whereby the bridge element receives more of the energy from the applied signal as the temperature increases. The EED is insensitive to coupled RF energy and to an electrostatic discharge since most of the energy from these stray signals is directed to the serpentine resistors and not to the bridge element. In another embodiment, two of the resistors are metal-oxide phase variable resistances and a third resistor is formed from a bowtie-shaped layer of zirconium. The resistances through the metal-oxide phase layers decrease with signal intensity whereby the zirconium can receive most of the energy from a high intensity firing signal. A shunting element, which may be placed across an EED, has a bowtie-shaped conductive layer formed on a substrate. The conductive layer explodes in a plasma above a certain signal intensity. The shunting element may comprise another type of device, such as a diode, capacitor, etc.
