Abstract: A method for revocable token identifiers may be employed in a shared storage environment. An access server may generate access tokens and include revocable token identifiers previously obtained from storage devices. When clients present access tokens to storage devices during storage requests, storage devices may check the validity of access tokens by verifying that the revocable token identifiers were previously issued to the access server. An access server may request that the storage device revoke revocable token identifiers. Storage devices may deny any future storage requests including revoked token identifiers. Additionally, an access token may include instructions specifying operations for a storage device to perform in conjunction with a storage request. A trusted server may issue grantor tokens granting permissions for access servers to use when issuing access tokens. An access server may then include such a grantor token in access tokens that it generates and issues to clients.

Abstract: A method and mechanism for managing access to a plurality of registers in a processing device are contemplated. A processing device includes multiple nodes coupled to a ring bus, each of which include one or more registers which may be accessed by processes executing within the device. Also coupled to the ring bus is a ring control unit which is configured to initiate transactions targeted to nodes on the ring bus. Each of the nodes are configured receive and process bus transaction with a fixed latency whether or not the first transaction is targeted to the receiving node. The ring control unit is configured to periodically convey idle transactions on the ring bus in order to allow nodes responding to indeterminate transactions to gain access to the bus.

Abstract: One embodiment of the present invention provides a system that uses directional weighting functions while computing optical flow for an image through belief propagation. The system operates by computing local velocity estimates for points in the image. The system also computes directional weighting functions for points in the image, wherein the directional weighting functions facilitate propagating information in a manner which can vary with direction. The system subsequently uses these directional weighting functions during a belief propagation process, which propagates the local velocity estimates between points in the image, and which computes an optical flow field for points in the image.

Abstract: System and method for displaying signals. First user input requesting display of a first signal is received, e.g., to a graphical user interface (GUI) comprised in a signal analysis function development environment, and the first signal programmatically analyzed in response to the first user input. A display tool operable to display the first signal is programmatically determined based on said analyzing, and the first signal displayed in the display tool, e.g., a data type of the first signal is determined, e.g., integer, floating point, Boolean, or user-defined data in a time-domain, frequency-domain, or spatial-domain, and the display tool programmatically determined based on the determined data type, e.g., via a loop-up table, where the display tool comprises an indicator operable to display the signal data. The signal comprises signal data, e.g., signal plot data, where the display tool comprises a graph, or tabular data, where the display tool comprises a table.

Abstract: The invention relates to a device for tensioning a threaded rod (1). The inventive device comprises: an actuator (5) which can exert an axial force; and a tie rod (6) which transmits the axial force from the actuator (5) towards a threaded end (1b) of the rod (1b), said tie rod (6) comprising at least two jaws (31) which can move radially between a closed position, in which the tie rod (6) is engaged with a threaded end (1b) of the rod (1), and an open position in which the jaws (31) are disengaged from the threaded rod (1b). Moreover, said device comprises a locking element (45) which can move between a jaw (31) opening position and a jaw (31) closing position.

Abstract: A calibration unit and technique for calibrating A/D systems (e.g., data acquisition devices) using a pulse-width modulation (PWM) circuit to reduce nonlinearity. The calibration unit may be coupled to an analog-to-digital module (ADM) of the A/D system. The PWM circuit may generate a calibration signal with intentional ripple, which may exercise a region of a transfer curve of the ADM to reduce local nonlinearities in measurements associated with the calibration of the system. Pulse trains of varying frequency and duty cycle may be generated to sweep the PWM circuit through an ADM range and to calculate an ADM linearity correction function, which may be used to perform gain and offset correction with respect to a best-fit line through an ADM transfer curve to reduce large signal nonlinearities. The PWM circuit may include a resistor divider circuit including a plurality of taps to calibrate small input ranges.

Abstract: Processes for the preparation of nanopalladium (0) catalysts are disclosed. In some embodiments, the nanopalladium (0) catalysts may be reusable. In some embodiments, the nanopalladium (0) catalysts may be heterogeneous. Nanopalladium (0) catalysts may be employed for preparing coupling products by C—C bond formation through reaction of haloarenes in the presence of base. Haloarenes used in the coupling reaction may include chloroarenes that are typically unreactive. The use of heterogeneous nanopalladium catalyst may preclude the presence of trace amounts of palladium in the final coupling product.

The information includes information characterizing quiesce capabilities and split characteristics for the logical storage object. That information is transmitted to a processor and is used to characterize the logical storage object.

Abstract: Methods and systems to bridge storage management software are provided. A first storage management application communicates with a host and performs an analysis of a storage environment associated with the host. The first storage management application uses the analysis to determine if a storage resource interface is controlled by a second storage management application, and if so a plugin application is accessed by the first storage management application to permit the second storage management application to perform a storage management operation on behalf of the host. In one embodiment, the analysis is updated by the first storage management application upon receiving results from second storage management application, where the results reflect the processing of the storage management operation by the second storage management application.

In one embodiment, an FPGA in a motion control device may be configured to perform the trajectory generation, interpolation, and control in parallel. Performing trajectory generation, interpolation, and control in parallel on an FPGA may increase the efficiency of the motion control application.

Abstract: The securing of a telephone link between the two subscriber sets is established on the basis of encryption keys transmitted over the service channel (D) of the ISDN network whether the link be established on the switched telephone network (PSTN) or on the Internet network (NSTN). A server verifies the identifiers of the subscriber taps (PA1, PA2) and stores the encryption keys.
