Patent ID: 7753750

Claim:
An electrically powered buoyancy and velocity of movement controllable life preserving vest and transport system, comprising: a life preserving vest including a top portion having an upper opening for receiving the head and neck of a wearer of the vest with a forward facing front portion and a rear facing rear portion of the vest releasably securable to enclose an upper portion of the body of the vest wearer while forming an open bottom for receiving a lower portion of the vest wearer; the forward facing front portion of the vest including (i) a centrally located vertically extending compartment containing a vertically extending propulsion unit oriented to generate a vertical lifting force on the vest wearer when the vest is in a vertical orientation and a forward horizontal propelling force on the vest wearer when the vest is in a horizontal orientation and (ii) a floatation unit including a floatation chamber extending vertically and laterally within the vest on opposite sides of and planar with the vertically extending compartment and the vertically extending propulsion unit contained therein to exert balanced upward forces on the vest wearer to add needed buoyancy to the vest wearer; and the forward facing front portion of the vest supporting user controllable means for controlling the buoyancy of the floatation unit and user controllable means for controlling the propulsion forces generated by the propulsion unit.
