  • Patent number: 8390979
    Abstract: A blasting control system includes a detonator module, and a blasting machine interface configured for serial communication between a blasting machine and the detonator module. The detonator module includes a detonator, a unique electronic ID, a switch configured to enable/disable the detonator in response to verification of the unique electronic ID, a communication device configured for communication with the blasting machine interface, and a processor responsive to instructions from the communication device. The blasting machine interface includes an I/O device, a communication device, and a processor responsive to the I/O device and the communication device. Upon verification of the unique electronic ID via communication from a user via the blasting machine interface, a state of the switch associated with the detonator is placed in an unlocked mode so as to enable activation of the associated detonator upon a fire signal from the blasting machine via the blasting machine interface.

  • Patent number: 7992494
    Abstract: 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.

  • Patent number: 5516971
    Abstract: An improved non-pyrolytic disposal process for nitrocellulose-based explosives and rocket propellants is disclosed. Explosive and propellant particles are digested by contact of the particles with an aqueous solution containing from about 5 to 20% by weight caustic (NaOH) maintained at a temperature of about 50.degree. C. to 100.degree. C. and under conditions of agitation until digestion is essentially complete. The resulting by product contains a mixture of depleted caustic and a water soluble sludge which can be disposed of or further processed. The process minimizes environmental concerns brought about by the open burning of high energy materials.
