  • Patent number: 7565359
    Abstract: An custom page server is provided with user preferences organized into templates stored in compact data structures and the live data used to fill the templates stored local to the page server which is handing user requests for custom pages. One process is executed on the page server for every request. The process is provided a user template for the user making the request, where the user template is either generated from user preferences or retrieved from a cache of recently used user templates. Each user process is provided access to a large region of shared memory which contains all of the live data needed to fill any user template. Typically, the pages served are news pages, giving the user a custom selection of stock quotes, news headlines, sports scores, weather, and the like. With the live data stored in a local, shared memory, any custom page can be built within the page server, eliminating the need to make requests from other servers for portions of the live data.

  • Publication number: 20090137376
    Abstract: A centrifuge is employed to continuously remove particulates from a fluid. In one embodiment, the centrifuge removes small particles of soot from lubricating oil of diesel engines. The fluid is introduced into the centrifuge through a distribution rotor so that vortexes are not propagated in the fluid. Laminar flow of the fluid down the sides of the outer rotor may contribute to the soot-removal effectiveness of the centrifuge.

  • Publication number: 20080277727
    Abstract: An electrostatic protection circuit has a transistor for pumping charge into the substrate and a transistor, including a parasitic transistor, for removing charge from the substrate and tabs. The circuit is enclosed by barrier that prevents the migration of charge from the region of the transistors. The added charge in the region of the parasitic transistor, resulting from the increased charge in the region of the parasitic transistor, increases the flow of current between electrodes of the transistor, thereby removing the electrostatic charge more efficiently. removing the electrostatic charge more efficiently.

  • Patent number: 7434355
    Abstract: An inflatable docking station for a Mars roving vehicle (Mars rover) provides a recharging station as well as a storage facility for the Mars rover during adverse environmental conditions. The docking station/garage allows for extended operational life for the Mars Rover, allows for the Mars rover to operate at the polar regions of Mars, where extreme cold conditions restrict rover operation, and provides for a warmer habitat for the Mars rover. Conventional planetary roving vehicles only be deployed from the warmer equator region of the planet surface. However, these roving vehicles may never explore the polar regions because the roving vehicle may not have enough stored power. The docking station/garage provides a remote outpost for, among other things, storing and recharging the Mars Rover to allow it to reach more remote areas.

  • Publication number: 20080210891
    Abstract: The invention relates to the handling of radioactive material. For instance, a radiation shield of the invention may include a body having a cavity therein for receiving radioactive material. An opening to the cavity may be defined in the body. A base may be releasably attachable to the body (generally toward the opening) to at least partially enclose the radioactive material in the cavity. In the case that the radiation shield includes a plurality of interchangeable bases, one of the bases may have at least one of a shorter length and a lighter weight than another of the bases. The base(s) may be designed to enclose more than one size and/or shape of container in the cavity. The base(s) may include a hand grip to facilitate manual gripping of the radiation shield. The base(s) may include a guard to reduce exposure to radiation from manual handling of the radiation shield.

  • Publication number: 20080173592
    Abstract: A centrifuge is employed to continuously remove particulates from a fluid. In one embodiment, the centrifuge removes small particles of soot from lubricating oil of large diesel engines. The fluid in introduced into the centrifuge through an inducer so that vortexes are not propagated in the fluid. Flow constrainers and flow straighteners maintain laminar flow of the fluid as it passes axially through the centrifuge. An exducer decelerates the fluid prior to its exit from the centrifuge. The exducer thus contributes to maintaining laminar flow conditions. Laminar flow may contribute to the soot-removal effectiveness of the centrifuge.

  • Publication number: 20080038341
    Abstract: Dipeptidylpeptidase IV inhibitor (herein referred to as DPP-IV) that may be 98.5-100% pure is a high-dose drug capable of being directly compressed with specific excipients into sold form dosage forms, such as tablets and capsules having desired, hardness, disintegrating ability and acceptable dissolution characteristics. DPP-IV is not inherently compressible and thus presents formulation problems. Excipients used in the formulation enhance the flow and compaction properties of the drug and tableting mix. Optimal flow contributes to uniform die fill and weight control. The binder used ensures sufficient cohesive properties that allow DPP-IV to be compressed using the direct compression method. The tablets produced provide an acceptable in vitro dissolution profile.
