An inflatable flotation device including two panels extending from a body an inflatable bladder. The two panels and the body may be closed to enclose the inflatable bladder with the two panels attached to each other using magnets. When the inflatable bladder is inflated, the magnets separate from each other and the two panels open up to expose the inflatable bladder and allow further inflation.

A personal survival system for use in water includes an inflatable chamber (9) and in inflation system (31) operable to inflate the inflatable chamber (9), wherein the inflation system (31) is mounted separately from and remotely from the inflatable chamber (9). Also disclosed are: a survival system for use in water includes an inflatable chamber including an inner layer and an outer layer, wherein the inner layer is separate from the outer layer; an inflation control system for use with an in-water survival system, the inflation control system comprises a selectively sealable chamber configured to contain water-triggered automatic inflation device of the survival system; and a personal survival system including an inflatable bladder and a moulded cover constructed from a flexible polymer.

A hinged floatation device in which the two end portions of one elongate floatation panel are pivotably attached to the two end portions of another elongate floatation panel such that the floatation panels can be pivoted with respect to each other from a compact storage and carrying positioned, where one panel lies substantially flat against the other, to various deployed positions in which the two panels bow outwardly away from each other for sitting in the device while floating, laying on the device while floating, or floating in a vertical position with the device positioned around the user's torso.

The inventive concept discloses an inflatable life preserver device compacted within a wristband, in a convenient, minimally-sized form that operates simply by pulling of at least one rip-cord attached within the wristband. A floating plastic sac internal to the wristband is then deployed, and produces immediate mixing of water and internally contained, powdered acidic and alkaline substances. When the two types of substances are combined with a minute quantity of the water flowing into the plastic sac, a chemical reaction is created within the plastic sac. This condition generates, in the preferred embodiment, carbon dioxide gas. The entirety of the deployed plastic sac remains attached to the wristband. In this manner, the float device is inflated, providing substantial buoyancy, enabling the wearer to stay afloat in an emergency situation.

A life-saving device, including: a buoyancy bag including a cavity; a wearable member including a housing; a controller including a single-chip microcomputer, a battery, a flip-flop, and an integrated circuit board; a gas generator including an input electrode terminal and a gas outlet. The single-chip microcomputer includes a plurality of pins and is disposed on the integrated circuit board; the battery, the flip-flop, and the input electrode terminal of the gas generator are respectively connected to the plurality of pins through the integrated circuit board; the housing includes a first chamber, and the battery, the single-chip microcomputer, and the integrated circuit board are disposed in the first chamber; the cavity of the buoyancy bag communicates with the gas outlet; and the buoyancy bag is deflated when in nonuse for convenience of storage, and inflated with gas produced by the gas generator to expand in an emergency.

A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

A marker and recovery device comprising: an enclosure adapted to be secured to a wearer; a bladder configured to fit within the enclosure in an uninflated state, the bladder comprising: an elongate tube; a first upper tube fluidly connected to the elongate tube at a first end of the elongate tube; and a second upper tube fluidly connected to the elongate tube at a second end of the elongate tube; and an inflation mechanism to inflate the bladder to extend the bladder from the uninflated state to a deployed state in which the first upper tube and second upper tube join to form a handle portion at the end of the elongate tube.
