  • Patent number: 8377756
    Abstract: In one embodiment, the invention comprises a MOSFET comprising individual MOSFET cells. Each cell comprises a U-shaped well (228) (P type) and two parallel sources (260) (N type) formed within the well. A plurality of source rungs (262) (doped N) connect sources (260) at multiple locations. Regions between two rungs (262) comprise a body (252) (P type). These features are formed on an N-type epitaxial layer (220), which is formed on an N-type substrate (216). A contact (290) extends across and contacts a plurality of source rungs (262) and bodies (252). Gate oxide and a gate contact overlie a leg of a first well and a leg of a second adjacent well, inverting the conductivity responsive to a gate voltage. A MOSFET comprises a plurality of these cells to attain a desired low channel resistance. The cell regions are formed using self-alignment techniques at several states of the fabrication process.

  • Patent number: 7627615
    Abstract: Approach for versioning of documents is described. A version accumulator structure stores one or more version values indicating different versions of a data object. The data object is decomposable into a plurality of nodes. One or more copies of each node of the plurality of nodes are stored, where the one or more copies are associated with non-overlapping version ranges. A first request to perform a change to the data object is received. The first request specifies an effective version value for the change, which involves a particular node. The change is performed based on the effective version value and without making a deep copy of the data object. A second request to retrieve a certain version of the data object is received. The certain version is retrieved based on the version ranges associated with the one or more copies of each node of the plurality of nodes.

  • Patent number: 7412700
    Abstract: Files of software to be installed in a computer are packaged as follows. A source file is prepared to contain at least a declaration of an array of sufficient space to accommodate the files to be packaged. The source file is compiled into an executable file. Thereafter, the array in the executable file is overwritten with data from each file being packaged. Depending on the embodiment, the address of where each file begins in the executable file and each file's name may be stored in the same executable file or in a different file. The stored file names are used to identify an address of a file from its name, when the named file is first accessed. In several embodiments, the operating system loads the executable file as a library that is automatically shared by multiple instances of the application (or by multiple applications), to efficiently use physical memory.

  • Patent number: 7381230
    Abstract: The invention relates to reactor systems and processes for producing synthesis gas. In one embodiment, a reactor comprises a first reaction zone comprising a combustion catalyst, wherein the first reaction zone is operated at conditions sufficient to produce a combustion zone product comprising heat generated by the combustion of a fuel. The reactor further comprises a second reaction zone comprising a partial oxidation catalyst, wherein the second reaction zone is adapted to receive the combustion zone product and a reaction feed comprising a hydrocarbon gas. The second reaction zone is operated at conditions sufficient for partially oxidizing the hydrocarbon gas to a product stream comprising synthesis gas. The heat of combustion is transferred directly to the reaction feed by mixing it in a feed mix region located in the reactor between the first and second reaction zones, in such a manner that the reaction feed does not need preheating prior to entering the partial oxidation zone.

  • Patent number: 7281003
    Abstract: A method and mechanism are provided for accessing data. Values are stored for a set of context attributes associated with a session between a database user and a database server. The database system includes an attribute setting mechanism that selectively restricts access to the set of context attributes based on a policy. During the session, the database server executes a query that contains a reference to one or more of the context attributes. For example, the query may contain a predicate that requires a comparison between a context attribute value and a constant. The database server processes the query based on current values of the one or more of the context attributes referenced in the query. A mechanism is also provided for dynamically attaching predicates to queries, where the predicates are attached based on a policy. For example, the database system detects that a query is issued against a database object.

  • Patent number: 7264716
    Abstract: A membrane filtration manifold for connecting a filter submodule including one or more elongate bundles of semipermeable polymeric fibers is provided. The manifold includes a housing and connecting collar connected with said housing. The collar is adapted to receive and locate the submodule, where the submodule has a connecting sleeve with a locking formation. The submodule can be secured at one end to the collar by a clip adapted to engage both the collar and the locking formation to prevent axial withdrawal of the submodule from the collar. Also disclosed is a membrane filtration apparatus including a filter submodule including one or more elongate bundles of semipermeable polymeric fibers. The apparatus further includes a membrane filtration manifold removably connected at one end of said filter submodule and a basepiece removably connected to the other end of said filter submodule.

  • Publication number: 20060263151
    Abstract: A system and method are disclosed for the treatment of liquid runoff, such as rainfall, irrigation, and waste or produced water, utilizing aboveground, modular, permeable barriers containing reactive media that can immobilize particular solutes of concern, removing them from the liquid runoff. The modular design allows construction of a relatively-uniform barrier, or media volume, that is self-supporting and easily assembled, maintained, modified, and augmented. A permeable reactive barrier constructed according to the present invention provides significant contact between the reactive media and the solutes of concern while allowing the runoff stream to flow through the structure relatively unimpeded.
