A squib assembly for a non-electric initiator of an anti-personnel obstacle breaching system includes a housing configured to connect to the igniter of a rocket motor of the anti-personnel obstacle breaching system, a slider assembly slidably contained within the housing and configured to connect to a shock tube of the non-electric initiator, and a pyrotechnic element disposed within the housing. Upon activation of the non-electric initiator, the squib assembly is configured to mechanically puncture a base of a initiator sleeve of the rocket motor and to thermally initiate ignition of the rocket motor.

Non-electric initiator system

A remote detonator system is provided. The remote detonator system includes a receiver and a transmitter. The receiver includes a transducer configured to receive an ultrasonic acoustic signal. The transducer is electrically coupled to a first controller, the first controller having a processor responsive to executable computer instructions for detonating a charge in response to the transducer receiving the ultrasonic acoustic signal. A transmitter is provided having a transmitter configured to selectively emit the ultrasonic acoustic signal in response to an actuation by an operator.

Signal encrypted digital detonator system

Percussive signal transmission tubes, of contrasting color, are joined along adjacent longitudinally extending portions by an adhesive bead of polymeric material. The tubes can be separated in the field and are provided on spools without any sheath. A small diameter (0.10 inch) tube can be used to reduce the size of the spool, or increase the length of tubing wound on the spool. An apparatus for assembling the product is also disclosed.

Redundant signal transmission system and development method

Redundant signal transmission system and deployment means

An in-line initiator and firing device assembly includes a shock tube assembly. An in-line initiator is provided for initiating a shock wave along the shock tube assembly, and includes an end sleeve having a bore extending between input and output ends. At least a portion of a surface defining the bore toward the output end of the end sleeve is threaded for threadably receiving and forming threads on an outer surface of the input end of the shock tube assembly. A first retaining device is associated with the end sleeve for receiving a shock wave triggering device and securing the triggering device to the input end of the end sleeve. A firing device assembly is activated by a shock wave transmitted through the shock tube assembly. The firing device includes a barrel having a bore extending between input and output ends. The input end of the barrel communicates with the output end of the shock tube assembly and the output end communicates with a firing device. A firing pin piston is movably disposed within the bore of the barrel, and defines a cavity communicating with the input end of the barrel for storing a propellant charge to be initiated by shock waves transmitted from the shock tube assembly. A second retaining device is associated with the barrel for coupling the firing device to the barrel.
