  • Patent number: 10267002
    Abstract: In its various embodiments the claimed water current shield may be used to improve safety for a diver and/or a remotely operated vehicle (ROV) by lowering the water current shield with a crane with the louvers initially in a first position to allow water current to flow through the louvers, positioning the water current shield with hold-back rigging from an up-current side of the subsea work site, adjusting an open or closed characteristic of the louvers if drag from the water current needs to be reduced around the subsea work site, and closing the louvers to protect an object proximate the water current shield from the water current, thereby shielding divers and/or ROVs from water currents at an underwater work site. The water current shield generally comprises a frame; a predetermined set of louver assemblies operatively connected to the frame, where each louver assembly comprises one or more selectably movable louvers; and a louver mover operatively connected to each selectably movable louver.

  • Patent number: 9702337
    Abstract: A power generating apparatus using flowing water for rotating a shaft. Blades are mounted at a certain distance apart from each other on two straight sections of a chain. When the blades are immersed in water, water passes through the blades in the first straight section and then passes through the blades in the second straight section. The blades are caught on a stopper provided on the chain to be maintained in an oblique line. Direction adjusting devices are on curved sections. The oblique directions of the blades are in mutual opposition. The energy from the flow speed of water is changed into circulating power of the chain by the blades. The sprockets are driven by the chain (111), and drive rotating shafts.

    Abstract: The system includes a support structure with upstream and downstream pulleys rotatably supported thereby and with cables following circuits around each of the upstream and downstream pulleys. Prime movers, such as in the form of sail members, are attached to the cable. These prime movers have surfaces which are more perpendicular to the flowing water when on a downstream leg of the cable circuit than when on an upstream leg thereof. The prime movers are configured to rotate as they pass about the downstream pulley and upstream pulley to optimize their orientation to minimize drag when following the upstream leg of the circuit and to maximize surface area against which the flowing water acts when following the downstream leg of the cable circuit. Power is outputted from the system through action of the cable upon a power output such as an electric generator coupled to one of the pulleys.

    Abstract: A low-profile apparatus for converting water current into electricity. Fabric scoops are spaced along a continuous belt and, when submerged in a current of moving water, are pushed by the current thereby causing the continuous belt to move. The current pushes the fabric scoops downstream and then fold closed as the fabric scoops are rotated out of the water and travel back upstream. The moving continuous belt is used to turn an electric generator, which causes the apparatus to produce electrical energy. The apparatus includes one or more floats to support the continuous belt, electric generator, and other components of the apparatus. The apparatus can be moored or anchored in a variety of locations where there is moving water or currents. The apparatus maintains a low profile by using fabric scoops that collapse and fold flat when not submerged thereby reducing wind resistance and visible surface area above the waterline.

  • Patent number: 7645115
    Abstract: A linear fluid impulse engine enables efficient conversion of the kinetic energy of large volume flows of fluid at low velocity into useful work. The linear fluid impulse engine uses symmetrically curved blades that are mounted to continuous power transmission belts that revolve on a pair of axles. The blades move in substantially linear paths on both the upstream and downstream sides of the inter-axle plane, which extends between the axes of the shafts. A linear cascade of stationary mid-plane guidevanes, located between the two sets of moving blade cascades, acts as a row of nozzles, accelerating the fluid so that it interacts with the downstream blade cascade with the proper velocity characteristics of an impulse device. Water entering the upstream blade cascade may be accelerated by stationary guidevanes to enable impulse operation.

  • Patent number: 6948911
    Abstract: A water torque converter for extracting energy from the reciprocal motion of water beneath waves in a body of water comprising an open frame on which is mounted a rigid sail. The rigid sail is guidingly moved from one end of the frame to the opposite end of the frame by the reciprocal motion of the water. An elongated driving member is connected through a multi-clutch mechanism to the sail. This elongated driving member is also connected to an output shaft. The reciprocal movement of the sail results in the output shaft to be rotationally driven in one direction.

  • Patent number: 6920684
    Abstract: The fixed layers of all magnetoresistive elements that are formed on the same substrate are magnetized in the same direction. Chips including magnetoresistive elements are cut out individually from the substrate. A magnetic sensor is assembled by combining cut-out chips together with consideration given to the magnetization directions of the fixed layers of the magnetoresistive elements in the chips. In this manner, the fixed layers of the magnetoresistive elements are magnetized by a sufficiently strong magnetic field for magnetization, whereby an output signal having a large absolute value is obtained from the magnetoresistive elements.

  • Patent number: 6817180
    Abstract: The invention discloses a portable hydroelectric apparatus which converts the kinetic energy of water caused by gravity into electrical energy. This conversion is accomplished without the presence of a river or stream. A new type of buoyancy motor is disclosed which is formed as a U-tube erected vertically. One leg and the curved portion at the bottom are filled with a series of separate air-filled tanks. The other leg is filled with water, with a suitable seal at the bottom of the leg through which are made to jut 1½ tanks so the seal prevents water from leaking downward into the air space of the curved portion of the U-tube. Suitable means prevent the water column in the one leg from pushing the series of tanks out of the U-tube. The leading as well as the succeeding tanks behind it are made buoyant in sequence. In rising through the water-filled leg of the U-tube water is pushed through a nozzle which is made to operate hydroelectric devices.

  • Patent number: 6355988
    Abstract: A water lift generator system for generating electricity by a water system propelled by the force of water cycling through the system. A multi-chamber water lift system includes an down cycle converting the potential energy of water traveling downward through a down tube and out a nozzle or spout turned tangential to the main chamber to cause the chamber to rotate. The rotation of the system runs an up—cycle having several tee shaped tubes which operate to lift water from one chamber to the next higher chamber. The topmost chamber has an additional tee tube connecting the inner chamber with the down tube to complete the cycle. A water supply may be provided at the base of the machine to provide a closed cycle.

  • Patent number: 5865426
    Abstract: A human power amplifier includes an end-effector which is grasped by a human operator and applied to a load. The end-effector is suspended, via a rope, from a take-up pulley, winch or drum which is driven by an actuator to lift or lower the load. The end-effector includes a force sensor which measures the vertical force imposed on the end-effector by the operator and delivers a signal to a controller. The controller and actuator are structured in such a way that a predetermined percentage of the force necessary to lift or lower the load is applied by the actuator, with the remaining force being supplied by the operator. The load thus feels lighter to the operator, but the operator does not lose the sense of lifting against both the gravitation and inertial forces originating in the load. The operator has direct contact with the load (through the end-effector) there need be no switches, valves, keyboards, teach pendents, or pushbuttons in the human power amplifier to control the lifting speed of the load.
