Abstract: The present invention relates to a gas generator (10) comprising a body (12) delimiting at least one part of a combustion chamber (20), said part housing a primary pyrotechnic charge (16) adapted to generate gases in the combustion chamber (20) when said charge is initiated in combustion, and a slide valve (60) located outside said body (12) and defining with the latter a second chamber (66) housing a secondary pyrotechnic charge (74) whereof the self-ignition temperature is less than that of the primary pyrotechnic charge (16). A gas flow channel (50) for flowing gas out of the combustion chamber (20) is formed in the body (12). According to the invention, the slide valve (60) blocks this channel when it is in a first position, and under the effect of gases released by said secondary pyrotechnic charge (74), the slide valve is adapted to move to a second position wherein the channel (50) is no longer sealed off, allowing the gases contained in the combustion chamber (20) to flow outwards to the exterior.

Abstract: A tactical device holster (TDH) system is described that is a complete carry and deployment solution allowing for split-second deployment of hand-held non-lethal/lethal deployable devices (HNLDD) by tactical personnel. The TDH system allows tactical personnel to deploy HNLDDs without having to disarm because deployment requires only a single hand, and the TDH system indexes the HNLDD in the proper position for deployment. The TDH system allows the HNLDD to go from secure carry to deployment in under one second while not impeding the deadly force option during deployment. The TDH system keeps the fuze lever of the HNLDD fixed in a pre-specified position. The HNLDD is not altered for use with the TDH system and allows quick insertion of the HNLDD. The TDH system supports numerous HNLDDs and tactical pyrotechnic and incendiary devices, and can be fixed to various tactical clothing, vests, holsters, equipment, and vehicle components.
