  • Patent number: 11105003
    Abstract: A water electrolysis device comprises an ion exchange membrane electrolytic cell. The ion exchange membrane electrolytic cell includes an ion exchange membrane, a cathode chamber, an anode chamber, a hydrogen output tube, and an oxygen output tube. An anode is configured in the anode chamber, and a cathode is configured in the cathode chamber. The ion exchange membrane is configured between the anode chamber and the anode chamber. The hydrogen output tube is coupled to the cathode chamber, and the oxygen output tube is coupled to the anode chamber. When water is electrolyzed by the ion exchange membrane electrolytic cell, oxygen is generated by the anode and then exported through the oxygen output tube, and hydrogen is generated by the cathode and then exported through the hydrogen output tube. The hydrogen and the oxygen are exported from the same side of the ion exchange membrane electrolytic cell.

  • Patent number: 8275493
    Abstract: A system and method are provided for launching and recovering an unmanned, water-born vehicle (UWBV) from a mother ship. The UWBV mimics the behavior of dolphins and is positioned ahead of the ship in preparation for bow riding. The UWBV uses a guidance system to position and keep in the bow wave. A high-frequency (HF) sonar transceiver array aboard the ship computes and sends course corrections to maintain the UWBV within the bow wave. The frequency range of the HF array can be 100 kHz or higher due to the short distance between the ship and the UWBV. Accordingly, the HF array can have a small aperture allowing for accurate bearing resolution. Course corrections can be sent on a near-continuous basis such that changes in thrust and rudder angle can be minimized to allow for accurate control of the UWBV.

  • Patent number: 6914342
    Abstract: An engine control unit enablement circuit is disclosed that selectively closes a conductive path between a chargeable electrical energy source and electronics of an engine/motor. An engine position sensor provides feedback as to the rotational position of a rotating component of an engine to the enablement circuit. When the rotating component, e.g. crankshaft or flywheel, is rotating, the enablement circuit closes the conductive path and allows the transference of electrical energy from the energy source to the engine and motor electronics. Conversely, when feedback is received indicative of non-rotation of the rotating component, the enablement circuit opens the conductive path. As such, energy stored in the energy source remains stored. With a subsequent detection of rotation of the rotating component, the conductive is closed and the stored energy is allowed to pass to the engine and motor electronics thereby allowing faster powering of the engine and motor electronics.

    Abstract: A method for calculating parameters about an axisymmetric body in a cavity is provided. The user provides data describing the body, a cavity estimate, and convergence tolerances. Boundary element panels are distributed along the body and the estimated cavity. Matrices are initialized for each panel using disturbance potentials and boundary values. Disturbance potential matrices are formulated for each panel using disturbance potential equations and boundary conditions. The initialized matrices and the formulated matrices are solved for each boundary panel to obtain panel sources, dipoles and cavitation numbers. Forces and velocities are computed giving velocity and drag components. The cavity shape is updated by moving each panel in accordance with the calculated values. The method then tests for convergence against a tolerance, and iterates until convergence is achieved. Upon completion, parameters of interest and the cavity shape are provided.

  • Patent number: 6726515
    Abstract: The invention is directed to dead bolt receiver lock that is installed in a boat between the transom and the clamp that mounts an outboard motor to the boat. The dead bolt prevents the unauthorized removal of the outboard motor from the boat. To this end, there is used a dead bolt having at end thereof a rounded head and a another end thereof a threaded end. At the threaded end there mounted a fastening which receives a locking cylinder operated by a key to lock the dead bolt in a locked position to prevent the dead bolt receiver to be removed from the transom clamp combination to prevent any unauthorized removal of the outboard motor from the boat.

  • Patent number: 6672917
    Abstract: A process for forming an improved anodizing film on the surface of an aluminum alloy material. The film is impregnated with an amorphous substance which fills pores formed in the film during its growth. If the film has a flaw reaching the aluminum alloy material, the amorphous substance and aluminum form a layer of passivity which restrains the corrosion of the aluminum alloy material.
