Ignition and delay circuit

摘要

An ignition and delay circuit of an ammunition unit for time controlled delay of the initiation of an electric blasting cap. The ignition and delay circuit includes a piezo electric device generating electrical energy when hitting a target. An energy storing device stores the energy generated by the piezo electric device. A delay device supplied by the energy storing device and controlling the initiation of the electric blasting cap. A programmable micro processor is provided supplied by the energy storing device and arranged to control the delay of the initiation in dependence of at least the type of ammunition in question.
