  • Patent number: 8416834
    Abstract: A technique for wirelessly transmitting management data without cables in a data center is provided. Management data is obtained at a device in the data center. A wireless management data signal is generated from the management data. The wireless management data signal is configured to be transmitted at frequencies matching an ambient electromagnetic noise emitted by the data center, such that the wireless management data signal is masked in the ambient electromagnetic noise emitted by the data center. The wireless management data signal is wirelessly transmitted to another device.

  • Patent number: 8416841
    Abstract: Multiple input multiple output (MIMO) receiver circuitry is described. In one circuit, input circuitry provides a matrix of unresolved symbols received from a plurality of receive antennas. Channel estimation circuitry constructs a plurality of channel matrices including at least two channel matrices corresponding first and second subcarriers, respectively. A preprocessing circuit receives input from the plurality of channel matrices and interleaves retrieved input into an input matrix. A first systolic array includes boundary cells and internal cells. The boundary cells and internal cells are configured to perform triangulation and back-substitution on the input matrix to produce an output matrix. A second systolic array performs right and left multiplication operations and cross-diagonal transpose on the output matrix to produce a weighted matrix.

  • Patent number: 8417367
    Abstract: A manufacturing exception handling system is described for use with a manufacturing execution system that controls a semiconductor manufacturing process. The present invention provides real time information to the user that identifies restrictions that have been placed on the use of entities and inventories in the semiconductor manufacturing process. The present invention also provides real time information to the user that identifies the persons who are authorized to remove the restrictions. The present invention saves the time and effort that would otherwise be required to find out why a restriction existed and who could remove the restriction during the semiconductor manufacturing process.

  • Patent number: 8417858
    Abstract: Embodiments of the present invention provide for an IOC that does not limit each CPU to a particular port. Instead, the IOC may allow each CPU to communicate with all ports. Thus, the IOC can process CPU communications to determine which port to send them to, and send them to the correct port as well as process incoming communications from the ports to determine which CPU to send them to and send these communications to the correct CPU. This may significantly increase the flexibility and efficiency of a storage network.

  • Patent number: 8417758
    Abstract: A method, machine-readable medium, and systolic array for left matrix multiplication of a first matrix and a second matrix are described. The first matrix is a triangular matrix, and a cross-diagonal transpose of the first matrix is loaded into a triangular array of cells in an integrated circuit. A cross-diagonal transpose of the second matrix is input into the triangular array of cells for multiplication with the cross-diagonal transpose of the first matrix to produce an interim result. The interim result is cross-diagonally transposed to provide a left matrix multiplication result, which is stored or otherwise output.

  • Publication number: 20130085351
    Abstract: A tissue analyte measuring device (2) includes a light source (4) structured to emit unpolarized light toward the skin surface of a subject, and a detector assembly (8) configured to receive light reflected the skin surface of the subject and the transcutaneous tissues of the subject, the detector assembly including a polarizing filter (12) and a number of light detector subassemblies (14). The polarizing filter is structured to filter out s-polarized light and pass only p-polarized light to light detector subassemblies. The light source is structured and positioned to emit the unpolarized light in a manner wherein the unpolarized light will exit the measuring device at a predetermined angle with respect to a normal to a light emitting plane of the measuring device, wherein the predetermined angle is an angle (the Brewster's angle) at which only s-polarized light will be reflected by the skin surface when the unpolarized light is incident thereon.

  • Publication number: 20130086413
    Abstract: A method for fast I/O path failure detection and cluster wide failover. The method includes accessing a distributed computer system having a cluster including a plurality of nodes, and experiencing an I/O path failure for a storage device. An I/O failure message is generated in response to the I/O path failure. A cluster wide I/O failure message broadcast to the plurality of nodes that designates a faulted controller. Upon receiving I/O failure responses from the plurality nodes, an I/O queue message is broadcast to the nodes to cause the nodes to queue I/O through the faulted controller and switch to an alternate controller. Upon receiving I/O queue responses from the plurality nodes, an I/O failover commit message is broadcast to the nodes to cause the nodes to commit to a failure and un-queue their I/O.

  • Publication number: 20130083610
    Abstract: A sacrificial memory bank is added to a block of regular banks in a memory to reduce dynamic power consumption of the memory. The sacrificial bank is accessed by a set of bit lines that is substantially shorter than corresponding bit lines extending through all of the regular memory banks. Memory read and write operations, which are addressed to one of the regular banks, are deliberately redirected to the sacrificial bank having the short bit lines. Tracking circuitry identifies the regular bank that was addressed for each location in the sacrificial bank. Data is moved from the sacrificial bank to a regular bank only when a new write operation does not match the bank of the previous write operation. Dynamic power is reduced because locality of reference causes access to the sacrificial bank without having to access a regular bank for most memory read and write operations.

  • Publication number: 20130083932
    Abstract: Various embodiments relate to determining an energy level of one or more sound components from a sound mix. Based on at least one sound mix signal received from a mixing device and at least one component signal received from one or more sound components, at least one signal value of the sound mix signal and at least one signal value of the component signal may be computed. The component signal corresponds to each of the one or more sound components. An energy level of the one or more sound components may be determined based on the sound mix signal value and the component signal value which corresponds to each of the one or more sound components. The energy level of the one or more sound components may be output in order to determine the energy level of each component in the sound mix.

  • Patent number: 8413093
    Abstract: Disclosed is an improved approach for managing, tracking, and querying hierarchical data in layouts. According to some aspects, hierarchical grids are employed utilizing a scheme that organizes physical objects into a set of gradually refined grids that avoids the need to maintain duplicates while enhancing the desirable characteristics of existing schemes, including fast query times, fast data structure initialization and reduced memory footprint. Each grid-cell may be further partitioned into sub-containers to more efficiently provide space pruning during query operations. According to one approach, structures maintained to track existence of objects in a descendent hierarchy.
