Abstract
Disclosed is a detonation initiator that can form part of a demolition assembly. The detonation initiator can include a linear actuator assembly having a core with a permanent magnet disposed with respect to a coil, and a firing pin coupled to the core and disposed along a longitudinal axis of the linear actuator assembly. A capacitor can be used to store electrical energy derived from an electrical pulse received by the detonation initiator. An electrical circuit can be used to monitor the charge on the capacitor and to discharge the capacitor through the coil of the linear actuator assembly to propel the core along the longitudinal axis of the linear actuator assembly when the charge on the capacitor reaches a charge threshold.

A detonation initiator comprising:
- a linear actuator assembly having a core with a permanent magnet disposed with respect to a coil, and a firing pin coupled to the core and disposed along a longitudinal axis of the linear actuator assembly;
- a capacitor for storing electrical energy derived from an electrical pulse received by the detonation initiator;
- and
- an electrical circuit for monitoring charge on the capacitor and discharging the capacitor through the coil of the linear actuator assembly to propel the core along the longitudinal axis of the linear actuator assembly when the charge on the capacitor reaches a charge threshold, wherein the electrical circuit includes a digital logic gate to monitor the charge on the capacitor, the digital logic gate configured as a comparitor to compare a representation of the charge of the capacitor with a reference voltage established from the electrical pulse used to charge the capacitor and wherein all operational power for the electrical circuit is derived from the electrical pulse.
