  • Patent number: 11582878
    Abstract: A visual display stand is shown and described. The display stand comprises a thin aluminum member that slopes downward and away from a display to which it is attached to a horizontal base section that rests on a support surface. The horizontal base is spaced apart from the screen in a direction away from the rear of the display. A rear support member is also provided but is concealed from view when looking at the screen side of the display. As a result, when the stand is attached to display and viewed from the front, it gives a gravity defying appearance because it appears that the weight of the monitor should cause the stand to tip over. Alternatively, the second member may be removed, and the display may rest against a wall.

  • Patent number: 11149760
    Abstract: An improved pistonless cylinder, including both single acting and double acting configurations, based on an Aramid fiber reinforced elastomer tubular which is highly stiff in radial direction against radial expansion and elastic in axial extension, so as to form a completely sealed, extendable and retractable pressure chamber and to be able to perform as well as, or better than, most of the conventional hydraulic cylinders in terms of load bearing capacities, maximum stroke distances and service durability. This improved cylinder employs no piston, piston rod, sealing seals or oil based hydraulic fluid, and utilizes non-metal materials to construct the majority of the parts for its extendable and retractable pressure chamber; therefore, this new cylinder can achieve significant weight and fabrication cost reduction. In addition, this new pistonless cylinder uses ordinary liquids, e.g.

  • Publication number: 20190331047
    Abstract: A vehicle throttle locking circuit and method are provided. A control unit receives detection voltages from a pedal sensor and, when a clamping actuation signal is ON, digital clamping voltages are gradually reduced according to the detection voltages. A D/A conversion unit converts the digital clamping voltages to analog clamping voltages. A variable voltage clamping unit clamps the detection voltages according to the analog clamping voltages. The gradual reduction of the digital clamping voltages are stopped when the detection voltages are already clamped at an idle condition so that the pedal is effectively locked at the idle condition. As such, the present invention not only provides anti-theft function, but also avoids traffic accident and hazard to the safety of the driver or passers due to the vehicle's sudden loss of power.

  • Publication number: 20180283093
    Abstract: A fixing device includes a main body; a first coupling member disposed on the main body for coupling to the upper rail; a second coupling member disposed on the main body for coupling to the cover plate. The second coupling member includes an engagement projection, which includes a base fitted into and slidable inside a slide groove. The slide groove is disposed on a surface of the main body facing the cover plate. The second coupling member further includes a bump protruding from the base and inserted into a groove in the slide groove, and the bump is movable between grooves along a first direction. The bump can move in the groove in a first direction and is stopped from moving in a second direction opposite to the first direction. Two ends of the engagement projection are different in configuration to specify the first direction.

  • Publication number: 20180261442
    Abstract: A high voltage RF power supply capable of supplying a varying amplitude RF signal at a fixed frequency to the electrodes of a mass spectrometer analyzer. The RF generator provides a high voltage, low current signal capable of changing its amplitude in response to an input drive signal. The RF generator circuitry comprises separate positive and negative driver channels interfaced to a class AB amplifier circuit. The separate positive and negative channels drive a pair of current amplifiers with the final output stage comprising an air-core step-up transformer. The RF generator achieves efficiency and stability with a minimum of electronics hardware while incorporating the use of a simplified RF feedback circuit. The RF generator may be used with a variety of mass spectrometer analyzers, particularly those of miniaturized or portable application.

  • Patent number: 9919778
    Abstract: Conventional ship launching airbags are made of several layers of rubber and fiber meshes bonded together by vulcanization. With the existing fabrication process, an airbag is strong in standing heavy pressure at its surfaces, but weak against the cutting by sharp edges of metal debris or oyster shells. An airbag's functional failure during a field operation can cause not only stoppage, but also explosion, hence a serious safety hazard. To overcome such structural weakness, a new type of airbags with anti-cutting capability is disclosed in which a conventional ship launching airbag is covered with a layer of anti-cutting armor made of steel cord ply sheets, a standard off-the-shelf product for the making of tires, embedded at the surface of the airbag's main body.

  • Publication number: 20180023265
    Abstract: An oil storage, loading and offloading system includes a submerged oil storage tank with multiple vertically placed flexible containers. The system directly connects to the topsides of an offshore oil production platform above water to assist oil loading and offloading operations. During loading, oil is pumped in and stored inside flexible containers, which are expanded to displace equivalent amount of water out of the oil storage tank; during offloading, oil is pumped out from flexible containers and the reduced volume of each contracted container is then filled in by the equivalent amount of water from the surroundings There is no physical contact between water and oil. The submerged tank on-bottom weight has a limited variation during the loading and offloading operations. This disclosed system can be utilized for fixed offshore platforms, especially for shallow water marginal field developments, and for deepwater floating platforms such as SPAR and semi-submersible (SEMI) structures.
