  • Patent number: 6912641
    Abstract: A distributed memory computing environment is structured with an invariant memory page pool. The environment includes a device, a memory, a hard disk, and an operating system running on the device. A device ID lookup table and a Memory Block ID Lookup Table are stored in memory. Copies of memory pages and their look up tables are stored on the hard disk. If the operating system is shut down, at subsequent system start-up, memory is divided according to the same divisions seen on the memory page copies saved in configuration files.

  • Patent number: 6872006
    Abstract: A new apparatus for facilitating connections between fiber optic cables. A fiber optic cable assembly having a retainer ring, a spring, and clip attaches a fiber optic cable to an ITA or receiver connector housing. An alignment sleeve assembly having an alignment sleeve housing, and alignment sleeve, and a clip attaches between the faces of a receiver module and an ITA module when they are mated. The receiver or ITA module includes a module support bracket and spring assembly for separating the travel and force required for mating the fiber optic cables from the force and travel required for mating a receiver and ITA.

  • Patent number: 6785674
    Abstract: A method and system for creating and searching a central linked list comprising a parent node which is situated at the center of a plurality of child nodes. Each child node has two double linked list pointers. One pointer points to the next child node, and the other pointer points to the parent node. Thus, matched data obtained at several child nodes moves immediately back to the parent simultaneously. The parent node contains the memory address and name of central linked list, a description of central linked list, and a description of the relationship between other parent nodes, as well as the relationship between each child node to its specific parent node. Each child node contains a node address, an attribute comprised of some or all of the stored data field and a link to the full data content that may reside on a file or in a database. Memory storage of the structure information is stored in system memory, such as, RAM.
