Abstract:
1. An impulse cartridge system including: a housing comprising a plurality of cavities; a plurality of squib cups, each squib cup containing an electrically activatable charge, said squib cups comprising a first and second surface, the first surface being expandable upon receiving a first amount of force from activation of the electrically activatable charge, expansion of the squib cup providing sealing of an interface between the first surface and a wall of an adjacent one of said plurality of cavities thereto, the first surface configured to maintain its sealing integrity up to a third amount of force generated by the electrically activatable charge, the second surface deforming or structurally failing when experiencing a second amount of force generated by the electrically activatable charge, the third amount of force being greater than the second amount of force and the second amount of force being greater than the first amount of force; two electrical input contacts; and circuitry that selectively transmits energy from the input contacts to the electrically activatable charges, the circuitry configured to apply energy to a first charge of the electrically activatable charges independently of application of energy to a second charge of the activatable charges, the circuitry operating consistently regardless of the polarity of the energy applied to the electrical input contacts.
