  • Patent number: 7107121
    Abstract: A storage system or subsystem, method of locating components in the storage system and program product therefor. Storage system components have fiducial marks identifying component location. A sensor is located at an expected fiducial location and a first pass search for the fiducial is conducted along a search path. A second pass search, if needed, begins at a position located, horizontally, between the first pass start position and the system accessor home location.

  • Patent number: 7107376
    Abstract: Systems and methods for controlling access by a set of agents to a resource, where the agents have corresponding priorities associated with them, and where a monitor associated with the resource controls accesses by the agents to the resource based on the priorities. One embodiment is implemented in a computer system having multiple processors that are connected to a processor bus. The processor bus includes a shaping monitor configured to control access by the processors to the bus. The shaping monitor attempts to distribute the accesses from each of the processors throughout a base period according to priorities assigned to the processors. The shaping monitor allocates slots to the processors in accordance with their relative priorities. Priorities are initially assigned according to the respective bandwidth needs of the processors, but may be modified based upon comparisons of actual to expected accesses to the bus.

  • Patent number: 7103532
    Abstract: An evaluator system accepts input textual messages in unknown languages and assesses which character sets, corresponding to languages, matches that message. Textual messages whose individual characters are encoded in 16 bit Unicode or other universal format are parsed, and character sets which can express each character and the accumulated correspondence is logged. When the character sets against which the message is being tested only provide partial matches, the invention can determine which offers the best fit, including by means of a weighting function. The evaluation technology of the invention can be applied to multipart documents, and to search engines and indices.

  • Patent number: 7099257
    Abstract: Methods are provided for overwriting data in a probe-based data storage device (1) wherein data is represented by the presence and absence of pits formed in a storage surface (4) by a probe of the device. Input data is first coded such that successive bits of a first value in the coded input data are separated by at least one bit of the other value. Overwrite data bits v0, v1, v2, . . . , are generated from the coded input data bits b0, b1, b2, . . . , and the overwrite data bits v0, v1, v2, . . . , are then used to overwrite data on the storage surface (4). According to a first method, the overwrite data bits are generated such that, if a pit represents a bit of said first value in the data storage device (1) then vi={overscore (b)}i?1, for i?1 and v0 has said first value, and if a pit represents a bit of said other value in the data storage device (1) then vi=bi?1 for i?1 and v0 has said other value.

  • Patent number: 7092280
    Abstract: A CMOS static random access memory (SRAM) array with dynamically asymmetric cells, an integrated circuit (IC) chip including the SRAM and a method of accessing data in the SRAM. Each column of cells is connected to a pair of column supply lines supplying power to the column. During each SRAM access, a higher voltage is applied to one column supply line in each pair of the columns being accessed to unbalance cells in the columns being accessed. Unbalanced cells become asymmetric during accesses and the supply imbalance favors the data state being written/read.

  • Patent number: 7089510
    Abstract: A method and program product for optimizing level converter placement in a multi supply integrated circuit. Each level converter is placed at a minimum power point to minimize net power and transitional delay from a first (low) voltage net source through the level converter and to a second (higher) voltage net sink. Then, inefficient level converters are eliminated. Level converters with fanin cones below a selected minimum cone size are deleted and low voltage sources to the deleted level converter reverted. Higher voltage level circuit elements receiving inputs from multiple level converters are replaced with equivalent low voltage circuit elements. Low voltage buffer driving level converters are both replaced by a single said level converter.

  • Patent number: 7089549
    Abstract: Embedded devices typically have an operating system, one or more file-systems, as well as a bootloader and other data components resident in flash memory. During software development and testing, there is frequently a need to selectively update a combination of such images. The described technique organizes the images in the flash memory such that one can speed up the update process by eliminating relocation of existing images. A command-driven update mechanism provides a flexible process—eg, one can upload the images back to a host, one can update the update code itself, etc. A start handshake is used that enables auto-detection of the embedded serial port that is used for the update.

    Abstract: An integrated circuit (IC) including at least one combinational logic path. The combinational logic path includes two types of logic blocks cells that compensate each other for fabrication parameter effects on cell transistors. The two types may be dense cells with field effect transistor (FET) gates on contacted pitch and isolated cells with FET gates on wider than contacted pitch. Dense cell delay changes from the FET gates being printed out of focus are offset by isolated cell delay changes.

  • Patent number: 7071934
    Abstract: A technique, system, and computer program for quickly and efficiently navigating through a comparison of different versions of a file. An abstract representation of the detected differences is provided in a separate navigation window or pane. This abstract representation is shown as one or more bars, which are formatted using one color for segments that are the same and a different color for those segments that are different. This allows the user to see, at a high level, the relative size of differences, the relative position of the differences, and how the differences are distributed throughout the files. The user can navigate through the differences using navigation controls that are synchronized between the navigation window (or pane) and a file comparison window. A novel use of hover help is defined. The navigation window and controls can be used with comparisons of any type of ordered data, such as text, audio, video, etc., and with comparisons of any number of versions of a file.

  • Publication number: 20060120043
    Abstract: An apparatus, system and method for cooling vertically stacked printed circuit boards (PCBs). In one embodiment, a first PCB is disposed within a substantially enclosed lower chamber inside a PCB containment housing. A second PCB is disposed above the first PCB within the housing to define a substantially enclosed upper chamber above the lower chamber. The second PCB includes one or more airflow apertures defined therethrough and providing vertical air flow coupling between the upper and lower chambers. An airflow actuating device is utilized to generate a primary forced airflow within the upper chamber which is substantially parallel to the surface plane of the second PCB. The primary forced airflow further induces a negative air pressure in the upper chamber such that a mixed convection airflow is established between the upper and lower chambers via the second PCB apertures.
