Compact, wearable, inflatable flotation

    New inflatable floatation device will be about the size of a mobile phone, and will be quickly inflated to provide support to exhausted swimmers.
    The device will be small enough to be strapped to the waist or gear. Pulling the trigger will cause the canister of compressed air to fill the tube, which will be bright yellow to make spotting by rescuers easier. The device will be attached to the user by a tether, and can be deflated and reused.
