  • Patent number: 9533744
    Abstract: A lightweight, rugged and easy-to-carry beach bag is well suited to serve a primary function as a tote for containing and transporting items useful during an excursion to a beach or other waterside location—items such as towels, swimwear, swimgear, sunscreen, snacks, drinks, reading material and the like. Should an emergency arise necessitating a rescue of a person in peril of drowning, the bag's contents are jettisoned, enabling a quick collapse of the bag as a chain of hinged flotation elements that form an upstanding sidewall of the bag folds in an orderly manner so the bag forms a compact, substantially flat flotation device well suited to serve a secondary function of keeping afloat the person in peril who forcefully grasps the flotation device so a rescuer can tow the person toward shore by pulling on a lengthy tether securely connected to the flotation device.

  • Patent number: 9194969
    Abstract: Disclosed are methods and systems for using tension feedback from steerable deflectors to adjust vessel turn time. In one example, a maximum tension for a second steerable first towed on a first side of the survey vessel may be determined. A radius of a turn of the vessel at a preselected speed may further be selected such that the tension on the first steerable deflector is less than the maximum tension. The vessel may be turned while moving at the preselected speed, wherein the turning of the vessel has the selected radius. Tension may be measured on the first steerable deflector during the step of turning the vessel.

  • Patent number: 4822309
    Abstract: The invention comprises generally square buoyant cushions. A separate fabric skirt is attached to each side of each cushion. Each skirt has fastening means so the skirts on one cushion can be fastened to the skirts on another cushion. If the cushions are stacked one on top of another, and the skirts of the stacked cushions are connected together, the skirts are sufficiently long so the buoyant compartment formed by the facing surfaces of the cushions and the connected skirts of the cushions will have sufficient volume for storing emergency supplies. In another configuration the skirts on the cushions can be connected together in side by side relationship to form a chain of buoyant cushions or a raft which can support a number of people so they will not drift apart in the water.

  • Patent number: 4657516
    Abstract: A life preserver device which is constructed with an inflatable inner bag located inside an inflatable outer bag, with the device being deployed in the back of a seat in an aircraft. When extremely rough turbulance is encountered or a crash landing is envisioned, pressurized air is supplied to the inner bag through a break-away tube, causing the inner bag to inflate, expanding the outer bag around it from the back of the seat to act as an impact cushion. Following a landing in the water, the device may be removed from the seat by breaking the break-away tube and causing the device to deflate, put on by the passenger, and the inflatable outer bag reinflated by a gas cylinder prior to exiting the aircraft into the water.
