  • Publication number: 20150007739
    Abstract: An explosive device using a semiconductor explosion initiator device provides an MOS capacitor formed on a semiconductor substrate and including a silicide layer formed over a doped silicon layer formed over an oxide layer. The oxide layer is formed on an N-well formed in a semiconductor substrate. A voltage source applies a voltage which may be a pulsed voltage, across the MOS capacitor sufficient to cause the avalanche breakdown of the oxide layer and the diffusion of metal from the silicide layer into the doped silicon of the N-well formed in the substrate. The chemical reaction between the metal and the doped silicon causes the generation of a plasma which ignites a pyrotechnic material or ignites or detonates other explosive material in contact with the semiconductor explosion initiator device.

    Abstract: A microelectrical mechanical system (MEMS) microgenerator cell and array is disclosed. The MEMS microgenerator cell of the present invention is effective in the conversion of thermal energy to electrical energy. In accordance with the present invention, an explosive material is loaded into a chamber. A diaphragm seals the chamber, containing a plasma material. The explosive material is subsequently heated to its ignition temperature thereby raising the pressure in the chamber until the diaphragm ruptures. The rupture of the diaphragm results in the flow of plasma out of the chamber. Upon exiting the chamber, the plasma is forced to flow between two parallel rectangular electrodes. A magnetic field is applied in a direction orthogonal to both the plasma flow and the electrodes, thereby generating an electromagnetic field sufficient to a power source for MEMS devices.

  • Patent number: 8166879
    Abstract: An ignition circuit for a detonator is disclosed. The circuit includes an igniter, a transient voltage suppressor (TVS), an energy source and a switch, all electrically connected in series with each other. Current flow through the igniter sufficient to ignite the igniter is prevented until an ignition voltage is applied across the TVS that is equal to or greater than the breakdown voltage of the TVS.

  • Patent number: 8069789
    Abstract: Fire, arm, and disarm signals are typically transmitted to electronic detonators via signal transmission lines. Traditionally, such signal transmission lines include wires wherein one end of each wire is soldered directly to printed circuit boards and/or other signal processing components retained within the shell of a detonator. Other ‘modular’ blasting apparatuses of the prior art provide means to connect signal transmission lines to detonators in the field. Signal transmission line/detonator contacts are susceptible to disruption, particularly when the signal transmission lines are subject to inadvertent tugging or tensile forces at the blast site. The present application discloses an electrical connector that enables secure connection between a signal transmission line and any detonator adapted to receive and optionally process electrical signals from the signal transmission line.
