Abstract: A life preserving device is shown having a body portion with a pair of floating sections which extend in opposite directions from a centrally located fold. Each of the floating sections has an aperture adapted to receive a wearer's head. The floating sections are foldable together along the central fold for use by a single wearer with the single wearer's head passing through both of the apertures. The floating sections are foldable apart for use by two wearers with each of the wearer's heads passing through a selected one of the apertures. A pressure sensing switch is shown for use with the life preserving device. The pressure sensing switch includes a pressure sensing membrane which is affixed to the body and which is responsive to an increase in inflation pressure within the floating section of the body to complete and actuate an electrical circuit. The electrical circuit can be used to power a radio transmitter to transmit a distress signal.

Abstract: A personal flotation assistance device includes a housing having an open end, a cover pivotally movable from a first position closing the open end and a second position opening that end, a container of pressurized fluid having a frangible membrane, a pin for puncturing the membrane, an expandable envelope disposed in an initially collapsed condition, and a gear assembly connecting the cover and pin. User manipulation of the cover to move the same from its first to its second position causes pin movement both rotationally about its axis and translationally along that axis into membrane puncturing abutment, thereby releasing the pressurized fluid for inflating the envelope to provide the user with flotation assistance. Cover movement to its second from its first position additionally serves to clear the housing open end thus enabling expansion of the inflating envelope outwardly from the housing interior.
