  • Patent number: 8601388
    Abstract: A method of efficiently adjusting a timeline in a time window. An application program displays a window that includes a graphical user interface (GUI), at least a portion of time-based data, a timeline, and a slider bar. If a click and drag occurs while a cursor is over the slider bar, the application moves the slider bar and changes a position of data displayed in the window by an amount corresponding to the movement. The application increases the timeline scale if the slider bar reaches an edge of the timeline. If a click and drag occurs while the cursor is over a handle on an edge of the slider bar, the application resizes the slider bar and adjusts the timeline scale to correspond to the slider bar scale. If additional time-based data is available and is not displayed, the application displays an indicator on a corresponding edge of the timeline.

  • Patent number: 8261312
    Abstract: A streaming file is constructed with a file header section that includes a file header object, a media data file descriptor, and an index descriptor. A hinting index section includes a first level hinting index with a linear organization corresponding to timing tick key values. A second level hinting index has a non-sequential organization corresponding to such timing tick key values. A special mark in the second level hinting index indicates that the first level hinting index must be consulted for a next timing tick key value. Such mark is positioned in the last of a sequential run of timing tick key values associated with its entries. A data section that can be put in a separate file, and it accepts media data blocks associated in sequential runs of timing tick key values as its entries. Thus hinting is provided for a non-sequential media data file.

  • Publication number: 20110301233
    Abstract: Novel polyisoprenylated benzophenone derivatives isolated from the plant Garcinia paucinervis. Among these new compounds, paucinones A-C (Compounds 1-3) contains an unexpected cyclohexane-spiro-tetrahydrofuran moiety. A 1-methylene-3,3-dimethylcyclohexane group never reported before was found in the structure of paucinone D (Compound 4). Structures of these compounds were elucidated with spectroscopic evidence. The relative stereochemistry of 1-4 was determined by NOESY correlations. These compounds a potent ability to activate caspase-3 in HeLa-C3 cells within 72 hours at a low concentration and significant cytotoxicity against HeLa-C3 cells.

  • Patent number: 7986656
    Abstract: A method for inter-network communication between a first and second user. The method includes receiving a first request for a location associated with the second user from a first switching system for a first network in response to a second request. The method processes information associated with the first request and determines a network identifier for a second network related to the location associated with the second user, and sends the first switching system a location message, including the network identifier for the second network. The method includes receiving a third request for routing information associated with the second user from a second switching system for the second network. The method determines a location directory in the second network for the second user and receives the roaming information for the second user from the location directory. The method then sends the roaming information to the second switching system.

  • Patent number: 7890909
    Abstract: An automatic custom block composition tool for composing custom blocks of an integrated circuit (IC) design that may include non-standard library cells. The tool includes program instructions that are executable to create and use a placement control file that includes instructions for use by the custom block composition tool to place the one or more non-standard library cells into the custom block layout. In addition, the program instructions may instantiate a leafcell for each non-standard and each standard library cell included in a netlist. The program instructions may access the placement control file and place each leafcell in a row of the custom block layout according to the placement control file. The program instructions may also pre-route power, clock and critical network signals, and generate a router control file used during remaining routing of the custom block by a conventional router tool.
