Patent ID: 6843694

Claim:
A personal flotation device for providing passive protection while in water comprising: a containment vessel including therein a device activation means in communication with a controller means and device powering means, said controller means communicatively linked to pressure sensing means, said pressure sensing means being operatively linked to at least one mechanical actuator means, said mechanical actuator means being constructed and arranged to cooperate with a valve structure constructed and arranged for release of pressurized gas from said vessel; and at least one inflatable body in fluid communication with said valve structure for receipt of said pressurized gas; said pressure sensing means being constructed and arranged for cooperation with said controller means wherein release of said pressurized gas is prevented until nominal safety parameters including a combination of specific depth of submersion and specific time of submersion have simultaneously been exceeded; said nominal safety parameters further include sensing of a specific type of motion; whereby said device provides passive flotation safety to a wearer while in the water.
