Abstract: The present invention relates to improved personal flotation devices and their methods of use. Advantageously, the devices and methods of the invention eliminate the need for a pyrotechnical firing mechanism, and compared to current devices, are less apt to be spontaneously activated by deterioration that is caused by storage in a humid environment or the passage of time. Instead, the devices and methods of use of the present invention incorporate electronic circuitry to activate automatic operation.

Abstract: A liquid-sensitive actuator for actuating a displacement responsive device, such as an inflator for a flotation device. The actuator comprises a sensing member within a housing which expands upon contact with a liquid entering the housing through an inlet. Expansion of the sensing member imparts displacement to the device and thereby causes its actuation. In the case of a flotation device, actuation may involve displacement of a trigger member to cause discharge of gas from a cartridge to deploy an inflatable cell. The sensing member may comprise a dried, compressed natural sponge member which expands rapidly and forcefully when immersed in water to actuate the device. A cover is provided for the housing which is movable between a latched, closed position substantially sealing the liquid inlet and an open position to permit entry of liquid into the housing. When the cover is in the closed position, the sensing member is physically immobilized to prevent premature activation of the actuator.
