  • Patent number: 9162800
    Abstract: A device includes a pressure container, a pressure reducer, and a valve. The pressure container contains a liquid container deformable under pressure. The pressure reducer provides a liquid which bears with a first (e.g., lower) pressure against a first connector of the pressure reducer and with a second (e.g., higher) pressure at a second connector of the pressure reducer. The first connector is connectable to the liquid container, and the second connector is accessible from outside the pressure container. Due to the pressure reducer, liquid from the liquid container can be provided with a second pressure at the second connector. The valve adds a gas to at least part of the interior space of the pressure container remaining after receipt of the liquid container, the gas having an overpressure, such that a liquid in the liquid container bears with the first pressure against the first connector.

  • Patent number: 8834069
    Abstract: A buoyancy compensation apparatus for underwater use by a SCUBA diver, includes a pressurized air source, a buoyancy vest including air chambers and a pressure regulating unit. The pressure regulating unit includes a chamber in communication with the vest air chambers and the pressurized air source. The pressure regulating unit also includes a normally closed air injection valve and a normally closed relief valve. The wall of the pressure regulating unit chamber includes a flexible portion that flexes inwardly when outside water pressure exceeds the pressure in the vest air chambers, which, in turn, opens the air injection valve. The relief valve opens when air pressure in the vest air chambers exceeds outside water pressure. The air injection and relief valves respond faster than the walls of the buoyancy vest air chambers so that the volume of the vest air chambers remain generally constant even as the diver changes depth.

  • Publication number: 20090280705
    Abstract: Method and system for detecting danger of drowning for a person in water. The method may comprise: determining whether the person is located in the water, measuring the pulse of the person, determining the position of the person, monitoring the capacity of an energy source on the person, transferring data from the person to a receiver on exceeding a boundary value of a pre-determined parameter, a gas chamber on the person is filled with gas and thereby buoyancy is generated, as well as optionally activating an alarm in the receiver. The method may further comprise measuring breathing frequency of the person, measuring pressure at the water depth of the person, measuring body position of the person, and comparing boundary value data and generated data to each other in an evaluation/signal unit as well as when the gas chamber is filled with gas and/or the alarm is activated.

  • Publication number: 20090061707
    Abstract: A portable personal self-operating life tube is disclosed, in which when a user is drowned in water due to a marine disaster or a fire and sinking of a ship, it automatically operates, so the user can save his life by just wearing the tube, and the tube is able to keep a user's a body temperature until a rescue comes after the tube is expanded along with the above features, and a life tube can be easily used without a particular care by improving the problems found in a conventional art in which a user feels bad when wearing a life tube since a conventional life equipment is not customized, and it is not portable and is not easy to use.

  • Patent number: 7458751
    Abstract: An active control releasable ballast system for dive equipment is disclosed which in one embodiment includes a removable pocket that is secured with a side release buckle within a fixed pocket. The buckle is required to be opened before the weight contained in the pocket can be dropped or given to another individual in or out of the water. Thus, the release of the weights is a conscious and deliberate act.

  • Publication number: 20080258968
    Abstract: The present invention relates to a salvage system for a life jacket capable of enabling quick rescue of a victim by quickly finding a victim wearing the life jacket using an artificial satellite and displaying an electronic map provided with the position of the victim and the image of the victim on a screen in real time, when a marine accident or an aircraft accident occurs, and more specifically, to the life jacket, with a marine position tracking terminal attached thereto, which transmits and receives radio signals to and from a GPS satellite and a relay satellite to track the position of the victim, and allowing greater buoyancy to be generated in the head and the chest regions on the surface of the water, when wearing it.

    Abstract: There is described herein apparatus for providing buoyancy and/or facilitating rescue of a person or object. The apparatus includes a tubular sleeve for securing the apparatus around at least a portion of a person or an object wherein longitudinal extension of the sleeve causes the diameter of the sleeve to contract radially to grip the person or object or a portion thereof and wherein longitudinal compression of the sleeve causes the diameter of the sleeve to expand. The apparatus may further include attachment means coupled to the tubular sleeve for attaching the apparatus to rescue equipment and/or for providing a handle and/or at least one flotation means coupled to the tubular sleeve.

  • Publication number: 20080188149
    Abstract: Personal flotation devices (PFD's), also known as life jackets, swim vests, etc., including various structures which promote an increased flow of air within the PFD thereby conveying warm, moisture laden air away from the wearer, and allowing at least some ambient air to reach the skin or outer clothing of the wearer. Either or both of at least two modes are provided for fluid passage or “venting.” One fluid passage mode is in directions parallel to an inner side (i.e. “lateral”), with fluid passages being defined by structures such as projections or within various three-dimensional permeable materials, such as spacer fabric. Another fluid passage mode is through an aperture in a buoyant intermediate layer. Depending upon the particular design, a blend or combination of these two modes is achieved.

  • Patent number: 7267509
    Abstract: A wrist mounted inflatable floatation device to provide temporary floatation support for a swimmer, boater, wader, or other person who is in the water. A wrist mounted floatation device is conveniently worn when someone is in the water or on a boat. It is attached to the wrist by a wrist strap which is adjusted for a snug fit around wrists of a variety of sizes. Mounted on said wrist strap is a deflated and folded inflatable bladder. Also mounted on said wrist strap are means for inflating said inflatable bladder when need for a floatation device presents itself to a user. The means can be high-tech gas storage devices, such as carbon nanotubes or chemicals, that when triggered produce a chemical reaction to produce either a gas or a gas filled polymer material, or a simple inflation tube and check valve, which allows a user to manually inflate the bladder. The bladder is attached to the wrist strap by a cord. When inflated, the bladder detaches from the wrist but remains attached to the wrist by the cord.
