  • Patent number: 7244348
    Abstract: A system and method for treating ballast water within an ocean going vessel by generating hypochlorite for treating the ballast water. The system comprises one or more hypochlorite electrolytic cells in fluid communication with a stream of ballast water. A chlorine analyzer is positioned downstream from the electrolytic cells to determine the chlorine concentration of the treated ballast water. A hydrogen separator is connected to the hypochlorite electrolytic cells for venting hydrogen. In the method of this invention, water is taken aboard the ship for ballast in one port. A treatment stream is separated from the ballast water stream and piped to hypochlorite electrolytic cells. Hypochlorite is generated into the treatment stream and the hydrogen byproduct is separated by the hydrogen separators. The treatment stream is then reintroduced to the ballast water to eliminate marine species and pathogenic bacteria from ballast water.

  • Patent number: 7227742
    Abstract: A system for organizing one or more accessory devices for a personal computer includes a first body structure that houses a first accessory device and an attachment unit detachably attached to the first body structure for attaching and detaching the first body structure mechanically to an outside surface of a personal computer (PC) component. According to the present invention, the attachment unit can be removed from the first body structure and attached to a second body structure that houses a second accessory device so that the second body structure can be attached to the PC component.

  • Patent number: 7169227
    Abstract: A method for making a free-standing, single crystal, aluminum gallium nitride (AlGaN) wafer includes forming a single crystal AlGaN layer directly on a single crystal LiAlO2 substrate using an aluminum halide reactant gas, a gallium halide reactant gas, and removing the single crystal LiAlO2 substrate from the single crystal AlGaN layer to make the free-standing, single crystal AlGaN wafer. Forming the single crystal AlGaN layer may comprise depositing AlGaN by vapor phase epitaxy (VPE) using aluminum and gallium halide reactant gases and a nitrogen-containing reactant gas. The growth of the AlGaN layer using VPE provides commercially acceptable rapid growth rates. In addition, the AlGaN layer can be devoid of carbon throughout. Because the AlGaN layer produced is high quality single crystal, it may have a defect density of less than about 107 cm?2.

  • Patent number: 6943867
    Abstract: A system and method for automatically determining the shipping weight and cost of a plurality of photofinishing items from a service provider without physically weighing the photofinishing order. A computer system receives photofinishing orders from the customers and associates an order ID with respect to each of the photofinishing orders. The orders are filled and sent to a packing station for assembling the photofinishing order. Each order is placed in a shipping package having the order ID thereon in a machine readable format. A reading device reads order ID and obtains information for determining the associated estimated weight for each package. A printer produces a manifest to be used in shipping the plurality of photofinishing orders wherein the manifest provides the estimated weight and cost for each of the orders that is given to the shipping agent for shipment to customers.

  • Patent number: 6829037
    Abstract: A system and method for verifying the validity of a customer order by a service provider. The service provider receives a photofinishing order for at least one photofinishing product. An estimated weight of the photofinishing order is determined based on the known average weight for each of the at least one photofinishing product and package that is containing the product and compared with the actual package containing the photofinishing order. The order is shipped if the difference between the actual weight and the estimated weight is within tolerance.

  • Patent number: 6816365
    Abstract: A laptop computer has a base, which base has a front and rear end. A display screen is mounted on a display screen mounting mechanism for movement between a closed position and a first open position, with the display screen adjacent the rear of the base, and a second open position with the display screen spaced above and forward of the rear of the base. The display screen is pivotally movable in both open positions. A keyboard assembly is mounted on the base for movement between a retracted position and an extended position, and a keyboard mounting mechanism guides the keyboard assembly between the retracted and the extended positions, and lifts the rear of the keyboard assembly when the screen is in the second open position. The mechanisms have cooperating structures to retract the keyboard assembly from the extended position responsive to movement of the display screen mounting mechanism.

  • Patent number: 5526228
    Abstract: A computer system unit which includes an acoustic dampening cooling fan shroud panel mounted on a rear surface thereof. The computer system unit is generally rectangular, encloses an electronic component package and includes a front panel and a pair of generally parallel side panels. An intermediate rear panel, generally parallel to the front panel, mounts one or more cooling fans which draw air through the generally rectangular unit. A cooling fan shroud panel which includes an acoustic noise reduction lining is then mounted to the intermediate rear panel. The cooling fan shroud panel includes an aperture for ventilation which is displaced from the mounting position of the cooling fans such that acoustic noise resultant from cooling fan operation is minimized. The aperture within the cooling fan shroud panel extends into at least one surface thereof which is not parallel to either the side panel or the intermediate rear panel wherein ventilation is substantially unobstructed by adjacent vertical surfaces.
