摘要： A device comprises a reactive semiconductor bridge including a conductive metal, a reactive material, and an overcoat. When a high current passes through the reactive semiconductor bridge, the conductive metal vaporizes into a high temperature plasma. The reactive material is coupled to the conductive metal such that the conductive metal experiences an exothermic reaction to the plasma. When the conductive metal turns to plasma, the overcoat material absorbs at least a part of the exothermic reaction of the reactive material and breaks into a plurality of particles that are propelled away from the bridge. A gap is disposed between the overcoat and a membrane, and an explosive material couples to the membrane. The plurality of particles crosses the gap and penetrates the membrane to ignite the explosive material in response to being propelled away from the bridge.

摘要： The networked electronic ordnance system connects a number of pyrotechnic devices to a bus controller using lighter and less voluminous cabling, in a more efficient network architecture, than previously possible. Each pyrotechnic device contains an initiator, which includes a pyrotechnic assembly and an electronics assembly. One or more pyrotechnic devices each contain a logic device having a unique identifier. The pyrotechnic devices are individually controlled by the bus controller by addressing the unique identifier of each logic device. Each pyrotechnic device preferably includes an energy reserve capacitor which stores firing energy upon arming. Both digital and analog fire control conditions are provided before an armed pyrotechnic device can be fired. A plurality of initiators and/or other components of the system may be packaged together on a single substrate and networked together via that substrate.

摘要： A semiconductor bridge igniter device (10) having integral voltage anti-fuse protection provides an electric circuit including a firing leg and, optionally, a monitor leg. The firing leg comprises semiconductor pads (14a, 14b) separated and connected by a bridge (14c) and having metallized lands (16a, 16b) disposed over the pads (14a, 14b) so that an electrical potential applied across the metallized lands (16a, 16b) will cause sufficient current to flow through the firing leg of the electric circuit to release energy at the bridge (14c). A dielectric layer (15) is interposed within the firing leg and has a breakdown voltage equal to a selected threshold voltage (V.sub.th) and therefore provides protection against the device functioning at voltages below the threshold voltage (V.sub.th). A continuity monitor leg of the electric circuit is comprised of either a fusible link (34) or a resistor (36) disposed in parallel to the firing leg.

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.
