  • 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.

    Abstract: A multi-chambered torque personal flotation device for corrective turning action of a weighted individual. The multi-chambered device is capable of being adjusted to provide a wide range of buoyancy as might be needed under differing degrees of ballistic protection. An eccentric mobile buoyant system complements a massive displacement required to float the armored victim by providing the energy required to reliably initiate corrective turning action, regardless of the gear worn, position of water entry, or state of consciousness of the wearer. In the event the conscious victim desires to shed the body armor, a series of quick release members allow the victim to shed their ballistics vest while retaining their life jacket. The integrated life jacket upon separation from the heavily ballasted body armor continues to provide reliable airway protection.

  • Publication number: 20040052585
    Abstract: The invention relates to diving apparatus (2) comprising a pump (4) that is actuated by muscular force. Diving apparatus (2) of this type is considered to be particularly dangerous, which prevents its widespread use. The aim of the invention is to improve on the disadvantages of diving apparatus of this type to such an extent that diving with such apparatus is made safer and the user is able to react appropriately to unforeseen circumstances. To achieve this, the diving weights (14) are fastened to the fresh-air tank (3) by means of surface zip fasteners (15), the traction element (6) lying between the pump (4) and the limbs, to which it is attached, has a quick-release device (19), the float is surrounded by a net, the float has a seat located below the surface of the water and each of the straps (20), which are used to fasten the fresh-air tank (3) to the diver (1), has at least one quick fastener (21), which can be opened easily by the diver (1).

  • Patent number: 6666623
    Abstract: A buoyancy control device includes a buoyancy compensator to be worn by a scuba diver, a compressed air tank, a depth or pressure gauge and a valve connecting the buoyancy compensator and compressed air tank for releasing air into and out of the buoyancy compensator. A microprocessor is connected to the depth gauge and the valve for controlling the amount of air in the buoyancy compensator in response to the depth of the diver. In addition, the microprocessor is programed for automatically controlling the rate of ascent of a diver under normal conditions and for a faster rate of ascent under emergency conditions. The device also includes an override function which allows a second diver to override the normal rate of ascent and to initiate the faster rate of ascent in an emergency.

  • Patent number: 6527479
    Abstract: A water safety and survival system is disclosed that provides a multi-chambered personal flotation device and break away counterweight that provides a heads-up righting moment that reliably positions a scuba diver's airway out of the water when at the surface, and provides for a comfortable heads down position during the dive. The break away counterweight stows the ballast needed to heel the diver into a heads up position in an inactive state. Once released, the counterweight drops away and becomes capable of actively rolling the diver's face out of the water into the heads up position. The counterweight is preferably utilized in conjunction with a buoyancy compensator that further provides for rotation of the diver into a heads up orientation, and that can provide buoyancy compensation for the counterweight.
