Abstract: An emergency vehicle flotation system has bladder(s) attached in a compressed state on a vehicle. An inflation initiating component comprising a selected one or more of a submersion sensor attached to the vehicle to detect water pressure indicative of submersion of the vehicle and a user interface device. Selectable force gas generator(s) (SFGGs) have one gas-generating propellant cells that are individually fired. The SFGG(s) have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate the bladder(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the one or more SFGGs. The controller enables the emergency vehicle flotation system to receive an inflation signal from the inflation initiating component, and to fire a selected number of the more than one gas-generating propellant cells to at least partially inflate the bladder(s).

Abstract: An adaptive force vehicle airbag (AFVA) system includes airbag(s) stowed in a compressed state within an interior of a vehicle. An impact sensor detects a change in motion of the vehicle indicative of a collision. Selectable force gas generator(s) (SFGGs) gas-generating propellant cells that are individually fired. The SFGGs have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate at least one of the airbag(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the SFGGs. The controller enables the AFVA system to: (i) receive an inflation signal from the impact sensor; and (ii) fire a selected number of the gas-generating propellant cells to at least partially inflate the at least one airbag.
