  • Patent number: 6529182
    Abstract: A circuit for controlling current flow though an LED backlight network, comprising a PWM circuit for receiving an input DC voltage (Vsource) and in response generating a chopped output voltage (Vsw), a filter for smoothing the output voltage (Vsw) resulting in a DC output voltage (Vout) for application to a first terminal of the LED backlight network. A resistance (Rcp) is connected between ground and a second terminal of the LED backlight network so as to create a node voltage (Vref) connected to a feedback input of the PWM circuit. In operation, the PWM circuit maintains a constant controlled current through the LED backlight network by regulating Vout in accordance with the node voltage (Vref).

  • Patent number: 6523270
    Abstract: An apparatus for use with a source of light including a first orientation device that includes a latitude scale, a latitude pointer rotatable about a first axis relative to the latitude scale, and a platform configured to support an architectural model. The platform is mounted on the latitude pointer such that rotation of the pointer about the first axis produces a corresponding change in the position of the platform relative to the latitude scale. The apparatus also includes a second orientation device that includes a time scale and a time pointer rotatable about a second axis relative to the time scale. The first orientation device is mounted on the time pointer such that rotation of the time pointer about the second axis produces a corresponding change in the position of the platform relative to the time scale without changing the position of the platform relative to the latitude scale.

  • Patent number: 6524664
    Abstract: A method for highly hydrophilifying the surface of an article by photoexcitation of a semiconductor photocatalyst and maintaining the hydrophilicity is disclosed. A layer containing a photocatalyst is formed on a substrate. Onto the surface of the layer are fixed a hydroxyl group upon photoexcitation of the photocatalyst and a physically adsorbed water molecule in the vicinity of the hydroxyl group upon photoexcitation of the photocatalyst. Thus, the surface is highly hydrophilified. Further, this surface, simultaneously with the hydrophilification, exhibits higher hydrophobicity.

  • Patent number: 6526408
    Abstract: A system and method for data record summarization and exception testing is provided in which a data viewer program forms a logical pipe for processing and presenting data records from an input data record source to summarization and exception testing programs. The data viewer program creates a virtual data record stored in the processor memory of the system, which is then presented directly to the summarization and exception testing programs for processing. By providing this logical pipe between the input data record source and the processing programs, the present invention eliminates the need for intermediate storage files on disk memory, and also greatly increases the processing efficiency of the system. The system also includes a summarization program that is capable of directly summarizing the virtual data records piped into it from the data viewer program, thus eliminating the need for a time-consuming sorting process prior to summarization.

  • Patent number: 6523030
    Abstract: The present invention is a method for operating a computer system to minimize the number of disk storage access operations used in creating an inverted database. This method divides a database into several smaller subdatabases. The documents of the subdatabases are decomposed into subdocuments. A postings list for each subdatabase is then created in which all the terms for the subdatabase are associated with the identity of each subdocument of the subdatabase in which the terms occur. The resulting postings lists for the subdatabases are then merged. The merge process sorts the postings of the subdatabases and merges common terms. The non-common terms are merged after the common terms. The process of sorting the postings list and then merging the common terms followed by the non-common terms minimizes the number of disk storage access operations required for creating the inverted database from a series of inverted subdatabases.

  • Patent number: 6513856
    Abstract: In a tarp system used to cover an open container such as a truck, the tarp being connected on one longitudinal edge to a roll bar, an improved mechanism for assisting movement of the roll bar comprises one or more constant force springs, each spring attached at one end to a longitudinal side of the container and at the other end to a reel mounted on the roll bar. When the roll bar is at one side of the container, the tarp is rolled around the roll bar and the constant force springs are extended. As the bar rolls across to the opposite side, the tarp is unrolled to cover the container opening, and the constant force springs wind into a coil around the reel.

  • Patent number: RE38064
    Abstract: A mobile metal building forming machine forms panels of predetermined length from a coil of flat metal and then the formed panels are continuously crimped on their side edges for strength and are selectively curved by crimping the bottom of the panel. The crimping and curvature are automatically controlled so that building panels with vertical walls and an arched roof may be formed. A moveable crimping roll is automatically portioned to control the curvature and the roll is chain driven so that it may be moved without affecting its rotational drive.
