  • Patent number: 7677507
    Abstract: A fixture is provided for a bag rack. The fixture has a wire frame with two mounting plates on it for mounting the fixture to two alternative locations on a bag rack. Two fixtures are mounted to each bag rack. Each fixture includes multiple rows of posts, with two posts in each row. Handles for a reusable bag are extended over arms on the bag rack and below the posts on the fixtures to keep the reusable bag open during filling.

  • Publication number: 20070045960
    Abstract: A gaming device stand including a back plate partially supported by a ground engaging surface and a cabinet having lower, upper, left and right panels. The upper panel has a surface for supporting the underside of a gaming device. The lower panel is cantilevered from the back plate and forms a clearance with the a ground engaging surface. The clearance is configured to accommodate the lower portions, e.g. feet and lower legs, of an individual playing the gaming device.

  • Publication number: 20060044046
    Abstract: A gate drive circuit capable of providing both positive and negative drive from a DC power supply is presented. The circuit includes an isolator stage, a driver stage, an optional tuning stage, an offset stage, a shaping stage, and a switching stage, each electrically coupled in the order described. The isolator stage provides electrical isolation from signal level circuitry. The driver stage boosts the power within the signal from the isolator stage. The tuning stage slows rising and falling edges along the signal from driver. The offset stage shifts the unipolar gate drive signal from the tuning stage into the negative voltage range. The shaping stage modifies the signal from the offset stage so as to ensure squared transitions. The switching stage enables voltage control. The described circuit is applicable to electronics utilizing a variety of voltage controlled switching devices.

  • Publication number: 20060044856
    Abstract: A high-frequency switch circuit is presented. The invention includes a pair of switches, a pair of inductors, and a pair of diodes. Inductors are electrically connected in series between the switches which are thereafter electrically coupled to a power source. Switches are electrically connected to gate drivers so as to control and coordinate the cycling of switches between ON and OFF states. Inductors are also electrically connected to an output thereby communicating a voltage waveform thereto. In some embodiments, it may be desired to electrically connect the inductors to an output circuit to further modify the waveform. Diodes are likewise electrically connected about the switches and inductors. The present invention is applicable to a variety of circuits having a totem pole arrangement of switches sequentially cycled ON and OFF, examples including but not limited to half-bridge, full-bridge, and hybrid configurations.
