DETONATOR SYSTEM HAVING LINEAR ACTUATOR

摘要

Disclosed is a detonation initiator (14) that can form part of a demolition assembly (10). The detonation initiator can include a linear actuator assembly (44) having a core (58) with a permanent magnet (60) disposed with respect to a coil (42), and a firing pin (50) coupled to the core and disposed along a longitudinal axis of the linear actuator assembly. A capacitor (40) can be used to store electrical energy derived from an electrical pulse received by the detonation initiator. An electrical circuit (38) 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.
