  • Patent number: 10781099
    Abstract: An underwater hydrogen generator can include a watertight reaction housing enclosing a metering chamber. The metering chamber can have an upper portion that terminates at a piston opening, and a lower portion that merges into a funnel, which can further terminate at a metering opening. The metering chamber can be filled with an acid accelerator, and the watertight reaction void can be partially filled with NaBH4 in solution. The generator can further include a seawater float valve that can be in fluid communication between the external environment, the metering chamber and the void defined by the reaction housing. The float valve, metering chamber and reaction housing can cooperate to generate hydrogen when said generator is submerged, by allowing seawater to contact both the acid accelerator and the NaBH4. The size of the metering opening can determine the rate at which acid accelerator is added to the NaBH4 solution.

  • Publication number: 20200248834
    Abstract: A valve for delivery of fluid between two chambers. The valve includes a plug, force spring that opens the plug, and a base that joins/mates with the inner surface of a chamber. Plug sealing mechanisms seal the plug to the base. Chamber sealing mechanisms seal an inner surface of a chamber bore or conduit. The valve also includes a trigger arm that holds the plug down until the trigger arm is actuated to cause the plug to move and the valve to open. The valve also includes a remotely-actuatable trigger for releasing the trigger arm. A channel permits the transfer of fluid from one side of the plug to the other.

  • Patent number: 10663666
    Abstract: This invention is a method and system for addressing structural weaknesses and geometric differentials introduced to a cable when splicing optic fibers. The apparatus and method utilize structurally integrated layers of protective polymers and bonding materials selected for strength and flexibility relative to their thickness. This results in an apparatus having a minimally increased circumference compared to the cable. The method and apparatus include one or more strengthening layers which allow the repaired cable substantially similar flexibility compared to the cable, but prevent formation of sharp bends or kinks. The strengthening layers also allow the repaired cable a resistance to tension similar to the original cable. The method and apparatus further include an outer layer having a geometric configuration which includes sloped terminating ends designed to prevent the reinforced area of the cable from being damaged by the force of objects or substances in contact with cable.

  • Publication number: 20200103040
    Abstract: A system and method for protecting a lightweight pressure vessel capable of airborne and underwater use. The system includes an enclosure and a gas container that is capable of holding pressurized or liquefied gas in sufficient quantity to increase internal pressure of the pressure vessel, so that the internal pressure of the pressure vessel equals an external pressure of the pressure vessel. The system also includes a pressure relief device coupled to the enclosure. The pressure relief device is configured to release the pressurized or liquefied gas from the pressure vessel when the internal pressure exceeds the external pressure by a predetermined amount. The system also includes a gas supply mechanism coupled to the gas container, the gas supply mechanism being configured to allow gas from the gas container into order to increase the internal pressure of the pressure vessel until the internal pressure equals the external pressure.

  • Patent number: 10569839
    Abstract: A buoy, comprising a body, an inflatable bladder, a bladder cover, a pressure vessel, a variable-volume, gas-filled chamber, a controller, a compressor, and a ballast. The bladder cover surrounds the inflatable bladder. When the inflatable bladder is deflated, the bladder cover is configured to compress the inflatable bladder so as to conform to an exterior contour of the body. The variable-volume, gas-filled chamber provides passive, variable buoyancy to the buoy. The controller is configured to control a transfer of compressible gas between the inflatable bladder and the first pressure vessel. The compressor is configured to remove gas from the inflatable bladder, compress the removed gas, and introduce the compressed gas to the first pressure vessel for storage. The ballast maintains a substantially vertical orientation of the buoy when the buoy is in water.

  • Patent number: 10487980
    Abstract: A pressure clamp for connecting pressure vessel segments and method can include a pair of semi-circular sections, which can be placed around the ends of the segments, so that there is a slight gap between the semi-circular sections. The inner surfaces of the semi-circular sections can be formed with two notches with beveled surfaces. The beveled surfaces can engage corresponding slanted surfaces on the segment ends, to urge the segments towards each other as the clamp is tightened. A pair of jack screws can be threaded through the semi-circular sections so that the jack screws extend slightly outwardly from one of the sections and contact the other section at the beginning of the tightening process, to establish an initial assembly gap. As fasteners tighten the clamp around the segment, the jack screws can be backed out to maintain a uniformly decreasing assembly gap between the semi-circular sections.

  • Patent number: 10461464
    Abstract: A bulkhead penetrator comprising a body having an interior and an exterior. An element having a first pressure is disposed within the body's interior in a first pressure region. An inner penetrator is configured to permit a transfer of the element from the body's interior past the physical boundary to the exterior of the body in a second pressure region having a second pressure, the inner penetrator having an interior surface exposed to the first pressure region and an exterior surface exposed to the second pressure region. An outer penetrator is configured to permit the transfer of the element from the interior of the body past the physical boundary to the exterior of the body in a third pressure region having a third pressure. An inner-outer connector connects the inner penetrator to the outer penetrator. Sealing mechanisms may prevent the transfer of the element from the first pressure region.

  • Patent number: 10338157
    Abstract: A biosignal measuring device that can include at least one Super-conducting Quantum Interference Device (SQUID) array (SQA) of High Temperature Superconducting (HTS) Josephson Junctions (JJs). The HTS JJs operating parameters can be adjusted to establish an anti-peak response for the SQA, that can be at a maximum along a defined response axis, for detection of extremely small biomagnetic fields. For operation, the SQA can be maneuvered around a target area of a stationary subject that is emitting biomagnetic signals using a stand with three degrees of freedom, so that the response axis remains orthogonal to the subject target area. The device can further include a radome with an atomic layer deposition (ALD) window on the radome surface. The radome ALD surface can allow for passage of magnetic signals through the ALD window and radome, while simultaneously preventing passage of infrared radiation therethrough.

  • Publication number: 20180052235
    Abstract: An optical navigation system and method for underwater vehicles. The system is disposed within a pressure housing to protect the system's components from high pressures at depths as great as the ocean's floor. The system includes an optical sensor that takes multiple images, e.g., an ocean floor, through a sensor lens. A light source produces a light beam that is offset from the sensor lens. The light source reflects light directly into the field-of-view of the sensor, e.g., on the ocean floor. Software is stored in memory resident within the housing. The software determines the offset of features between at least two images taken with the sensor. Navigation information derived from these images may include a vehicle's two-dimensional position.

    Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.
