ABSTRACT:
An electrical pulse generator comprising a closed magnetic circuit made up of permeable iron and permanent magnet material having a cup-shaped portion, a central rod shaped portion extending upwardly from the inside bottom of the cup portion and a generally flat disc-shaped removable keeper making contact with the cup-shaped portion and the upper end of the rod-shaped portion, an electric coil wound on a portion of said magnetic circuit such that on movement of the keeper away from the rest of the structure an electrical voltage pulse is generated in the coil, mechanical means such that on activation by a predetermined level of shock severity it forces the keeper away from the rest of the structure. In the preferred embodiment the keeper is at least two portions, the first of which is forced from the assembly by a first level of shock severity and the second portion by a second level of shock severity, the magnetic structure acts as its own inertial mass and is mounted in bearings in a cylindrical housing, with the bearings being in the form of continuous coil springs positioned in the annular space between the magnetic structure and the housing.
