  • Method for ordering image spaces to search for object surfaces
    Patent number: 6400846
    Abstract: A method determines a surface of an object in a sequence of images. The method begins by estimating a boundary of the object in each image of the sequence using motion information of adjacent images of the sequence. Then, portions of each image of the sequence are ordered to produce an ordered sequence of images. The ordered portions are exterior to the estimated object boundary. Edges in each ordered image are filtered using the motion information, and each ordered image of the sequence is searched to locate the filtered edges to form a new boundary outside the estimated boundary. The filtering and searching are repeated, while projecting the new object boundaries over the sequence of images, until the new object boundaries converges to a surface of the object.

  • Time division switching system
    Patent number: 4412322
    Abstract: A time division multiplex (TDM) switching network is disclosed in which at least part of the network comprises a space switching portion (TMS) and in which the need for duplication of the space switching portion, and like methods of achieving network reliability, is eliminated. Data from an incoming channel is partitioned into successive blocks, a prescribed number of which form a set of blocks. The blocks are of predetermined size. Each of the blocks of a set is switched via different paths of the space portion of the network. A single network fault can therefore cause the loss of only one block of data in a set. This loss can be made insignificant in the case of data representing telephone conversations. For data not representing telephone conversations, error checking and correcting information is added to the set before transmission through the space portion of the network and errors occurring during transmission are corrected thereafter.

  • Server for executing client operation calls, having a dispatcher, worker tasks, dispatcher shared memory area and worker control block with a task memory for each worker task and dispatcher/worker task semaphore communication
    Patent number: 5617570
    Abstract: A server for executing operation calls by a client, including a dispatcher, a plurality of worker tasks, and a dispatcher shared memory area and worker control block for each worker task. Each operation call provided from a client is a sequence or one or more remote procedure call requests and each includes a packed buffer containing parameters. The dispatcher receives a buffer directly into the dispatcher shared memory space of the worker task selected to execute the remote procedure call request, sets the semaphore and sends a request acceptance response. The selected worker task unpacks the buffer into its memory space, executes the request, places the results into a packed buffer in its dispatcher shared memory area and sends a remote procedure call to the dispatcher. The dispatcher executes a remote procedure call to the client and sends the result buffer directly from the shared memory area.

  • Space-Time Precoding and Associated Feedback Generation Methods in Multiple Antenna Systems
    Publication number: 20110268215
    Abstract: A quantized multi-rank beamforming scheme for multiple-antenna systems such as a multiple-input-multiple-output (MIMO) wireless downlink. User equipment (UE) estimates downlink channel and transmit power and determines rank and power allocations. A quantized beamforming matrix is then determined by the UE using successive beamforming. The UE also determines channel quality indices (CQI) which it feeds-back to the wireless downlink base station along with the index of the quantized beamforming matrix. The base station uses the CQI information to select a UE for scheduling of downlink transmission and the quantized beamforming matrix index received from the selected UE to beamform the downlink transmission to the UE. Base station overhead and is minimized while providing near-optimal performance given the constraints of a limited feed-back channel and computational complexity of the UE.

  • Log based data architecture for a transactional message queuing system
    Patent number: 6353834
    Abstract: A message queuing system is provided that saves and stores messages and their state in an efficient single file on a single disk to enable rapid recovery from server failures. The single disk, single file storage system into which messages and their states are stored eliminates writes to three different disks, the data disk, the index structure disk and the log disk. The single disk, single file storage is made possible by clustering all information together in a contiguous space on the same disk. The result is that all writes are contained in one sweeping motion of the write head in which the write head moves only in one direction and only once to find the area where it needs to start writing messages and their states are stored.
