  • 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.

  • Publication number: 20170369142
    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.

  • Publication number: 20170336027
    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: 9061739
    Abstract: A self-stabilizing buoy and deployment methods can include a main body and a cage that can be attached to the main body. A ballast can be slidably positioned within the cage so that the ballast moves from within said cage to outside of the cage when the buoy is deployed. The cage can be formed with at least one slot. The buoy can include a locking mechanism to fix the ballast at the distal end of cage after deployment, which can include a locking head that can be fixed to the ballast and inserted into the slot, and at least one flexible cantilevered arm that can extend from the cage into the slot at its distal end. As the buoy is deployed, the weight of the ballast can be sufficient to urge the locking head past the cantilevered arm to fix and lock the ballast during buoy deployment.

  • Publication number: 20150160415
    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.

  • Patent number: 8866319
    Abstract: A pair of reverse-scissoring arms are configured to be rotatable and reverse-scissorable about a common central axis point. A volume expandable and volume contractible truck is operably disposed at each of the distal ends of the reverse-scissoring arms. Actuation of the arms simultaneously expands one of the trucks, increasing its volume, while contracting the other of the trucks, decreasing its volume. Operably coupled to each of the reverse-scissoring arms is an energy-supplied electric motor-generator. Energization of the motors actuates the arms, whereas actuation of the arms without energization of the motors generates electrical power in the motors. When submersed in liquid, the simultaneous expansion and contraction of the volume in the trucks generates positive and negative buoyancy, respectively, enhancing the dynamics of the truck expansion/contraction motion and the reverse scissorable arm actuation.

  • Patent number: 8771634
    Abstract: The present subject matter provides heat management while generating hydrogen gas from a hydride achieved by coupling a hydride with a hydrate. The present subject matter unexpectedly provides improved methods so that the heat released by the hydride during hydrolysis is accurately balanced by the heat absorbed by the hydrate as the hydrate undergoes a phase transition to a less hydrated or to an anhydrous form. Examples of heat-moderated hydrogen generating systems are provided, and include, among others: NaBH4/Na2SO4.10H2O, NaBH4/CoSO4.7H2O, and NaBH4/FeSO4.7H2O. The subject matter provides a methodology for determining the correct proportions of hydride/hydrate to use in preparing a hydrogen generator capable of operating at a nearly constant temperature at or near a phase transition temperature of the hydrate or at a higher temperature that is still within a desired temperature range, such as, for example, 30-90° C.

  • Patent number: 8567744
    Abstract: A reusable device for detachably mounting an object to a platform includes a breakaway plate that is mounted to the object and a mounting bracket that is fixed to the platform. The breakaway plate is formed with a circumferential groove, and an o-ring is placed in the groove. A tooth ring having a slight gap is positioned over the o-ring. As a retaining ring is placed over the o-ring and tooth ring and fastened to the mounting bracket, the tooth ring compresses, which causes the o-ring to compress and engage the tooth ring at a breakaway force of the object. When an applied force that is greater than the breakaway force is applied to the object, the o-ring pops out to separate the object and platform. The o-ring durometer is chosen according to the magnitude of breakaway force that is desired by the user.
