  • Geographic information system
    Patent number: 7725529
    Abstract: Disclosed is a geographic information system which comprises a multithreading client and a multithreading server cluster. The multithreading client includes at least one user interface, at least one client coordinator, map data, at least one map manager, at least one client-side spatial analyzer, at least one cache manager, at least one data requester, and at least one information communicator. The multithreading server cluster includes: at least one servlet, at least one image accessor, at least one map configuration mechanism; at least one data storage access mechanism, at least one data source manager, and at least one server-side spatial manager.

  • ATM layer device
    Patent number: 5889778
    Abstract: An ATM layer device for interfacing between a physical layer device and an ATM switch, which includes means for prepending and postpending of switch routing information to cells destined to enter the switch and for removing such information from cells having left the switch
    Type: Grant

  • Integrated user network interface device
    Patent number: 5568486
    Abstract: A method of interfacing between a non-continuous stream of cells of data and a continuous stream of frames of data, which includes transforming an incoming non-continuous cell stream into a continuous transmitted stream by inserting idle or non-assigned cells into the data stream during idle periods. The cells in the continuous stream are then mapped sequentially and contiguously onto the payload portions of frames. The frames are then transmitted synchronously.

  • Vibration-resistant battery having individually supported storage cells
    Patent number: 5389460
    Abstract: A battery (20) includes a battery container (22), a base (30) attached to the interior of the wall (24) of the battery container (22), a compliant first weld ring (32) extending to a first side of the base (30), and a compliant second weld ring (34) extending to a second side of the base (30). A first electrochemical storage cell stack (36) is supported on a core (42) extending from the first weld ring (32), and a second electrochemical storage cell stack (38) is supported on a separate core (42) extending from the second weld ring (34). Each of the storage cell stacks (36,38) includes a set of storage cells (40) and a gas screen (68) between each of the storage cells (40). The gas screens (68) are dimensioned to extend outwardly to contact the wall (24) of the battery container (22), thereby serving to damp vibrations in the storage cell stack (36, 38 ).
