Abstract: A method and apparatus to provision a plurality of server blades from a modular server system with operating system software is described.

Abstract: A motor that includes a stator that contains a first winding and a second winding driven by alternating currents. The rotor is arranged to rotate relative to the stator and contains a third winding and a fourth winding for generating a magnetic field with an amplitude and a phase angle relative to the alternating currents in the first and second windings of the stator. The motor includes a circuit in communication with the third and fourth windings for controlling the phase angle of the magnetic field and generating a rotating magnetic field that is in phase-lock with the alternating currents in the first and second windings of the stator. The motor also includes a control circuit and a comparator. The control circuit has an angular position feedback device for measuring the phase of the stator and the angular position and velocity of the rotor.

Abstract: A computer telephony interface (CTI) applications computer interfaces to a Internet telephony system which utilizes, preferably, the session initiation protocol (SIP). In one preferred technique, an additional pass through server is added to connect end users to their associated SIP proxy server, and to connect a CTI applications computer to the system.

Abstract: A method and apparatus to perform sample rate conversion using multiple Multiply-Accumulate (MAC) units are described.

Abstract: Displaying characters on a dot-matrix display includes characters for display on a display device and an array of pixel boxes for displaying the characters, where each of the characters is justified against one side of the pixel box included in the array of pixel boxes and occupies a standard width of four pixels in the pixel box.

Abstract: A technique is provided for breaking a stalled condition or livelock in a processor having a replay queue. A livelock or stalled condition is detected. One or more instructions are temporarily stored in a replay queue. A release or break in the livelock or stalled condition is detected, and the instructions are then unloaded from the replay queue for replay or re-execution. For a multi-threaded processor, a stall is detected in one of the threads. Instructions of the stalled thread are temporarily stored in a replay queue, except the oldest instruction of the stalled thread which is allowed to replay or re-execute. This allows other threads to have access to execution and replay resources. Eventually, the oldest instruction will execute and retire, which breaks or releases the stalled thread. The instructions stored in the replay queue are then unloaded from the replay queue.

Abstract: In an echo cancellation system, an echo canceler has an echo channel signal input, a reference channel signal input and a control output, the two inputs being uncorrelated, and a delay buffer has an input for a reference channel signal, an output in communication with reference channel signal input and a control input in communication with the control output from the echo canceler.

Abstract: A table-driven, integer-based method for approximating down sampling of wave data is disclosed. This method provides an efficient approximation of the desired down sampled wave data without a significant impact to overall system performance. Integer calculations are exploited by: (1) multiplying all values of ti by a large enough value to include all significant portions of the decimal value; (2) making all values of &Dgr;t integer values; and (3) using integer arithmetic for most calculations of &Dgr;t and ti. The following static integer tables assist in the final calculations: (1) T[ ], where each element contains the value of ti divided by &Dgr;t and multiplied by a large enough value, M, to place all significant decimal values to the left of the decimal; and (2) D[ ], where each element contains the number of samples of San to drop before arriving at a useable San and San+1 pair.

Abstract: In an example embodiment, an interface is provided between a software application and a hardware device transferring data between the software application and a network. The interface posts a request from the software application and, in response to a first polling inquiry received from the software application, determines whether or not an event signal corresponding to the request has been provided to it from the hardware device. The interface carries out a rearm routine if an event signal has not been provided at the time of the polling inquiry. A second polling inquiry is made by the software application after the interface is rearmed and the interface determines whether or not an event signal has been provided to it by the hardware device. The interface then carries out a wait routine which waits for the event signal if an event signal was not provided at the time of the second polling inquiry.

Abstract: Briefly, in accordance with one embodiment of the invention, a method of reducing flicker in a video image sequence includes the following. Successive video images are temporally filtered. The filter length is adjusted so as to reduce the amount of filtering across temporal discontinuities in the video image sequence. Briefly, in accordance with another embodiment of the invention, a method of reducing flicker in a video image sequence includes the following. Successive video images are temporally filtered. The filter length is dynamically adjusted.

Abstract: Briefly, in accordance with one embodiment of the invention, a circuit includes: a DC-to-DC converter. The DC-to-DC converter includes a plurality of ripple regulator DC-to-DC converter circuits. The plurality of circuits are coupled so that the output signals produced by each of the ripple regulator DC-to-DC converter circuits is out of phase with respect to the other of the ripple regulator DC-to-DC converter circuits.
