Abstract: A system and method for synchronizing a receiver of a bit stream to the bit stream include a correlator to remove the PN code modulation and to generate a stream of time sequence values (samples) from the received bits. A plurality of accumulators are included, each accumulator corresponding to an offset in a series of time intervals starting with a first time period. The accumulators add a number of values equal to a number of samples in a bit period. The values added by each accumulator is a set of values starting with the value at the offset corresponding to the accumulator. A plurality of magnitude calculators receives a sum from the corresponding accumulator and calculates a magnitude. A plurality of non-coherent summers are then used to add the magnitudes for each offset in each bit period for all of the received bits.

Abstract: A device has a processor for processing a vertex processing stage, a sub-screen dividing stage and a pixel rendering stage of a three-dimensional (3D) graphics pipeline. The processor includes processing threads which balance the work load of the 3D graphics pipeline by prioritizing processing for the pixel rendering stage over other stages. Each processing thread, operating in parallel and independently, checks a level of tasks in a Task list of sub-screen tasks. If the level is below a threshold value, empty or the sub-screen tasks are all locked, the processing thread loops to the vertex processing stage. Otherwise, the processing thread processes a sub-screen task during the pixel rendering stage.

Abstract: In a transmitter, data segments are transmitted in accordance with a predefined data protocol. The predefined data protocol is modified to define a first segment size and a second segment size. The first segment size represents a minimum segment size that can be transmitted. The second segment size represents a maximum segment size that can be transmitted. A segment is created and transmitted whenever a quantity of time-sensitive information available for transmission allows a segment to be constructed having a segment size between the minimum segment size and the maximum segment size. A segment of any size up to the maximum segment size is also created and transmitted whenever any time-sensitive information is available for transmission and an acknowledgement message is received by the transmitter.

Abstract: The present invention uses the one or more on-line process analyzers that monitor the manufacture of petroleum products, such as gasoline or diesel fuel, to analyze and/or certify that the manufactured product meets regulatory and/or contractual requirements. The analysis is performed by re-introducing a manually or automatically collected sample that is representative of the manufactured product back into the one or more process analyzers. The results obtained for the representative sample from the on-line process analyzers are then used to represent the quality of the manufactured batch of petroleum material to certify that the manufactured batch meets regulatory, specification and/or contractual requirements.

Abstract: A three-dimensional (3D) graphics pipeline which processes pixels of sub-screens in the last stage (pixel rendering) in parallel and independently. The sub-screen tasks are stored in a list in a shared memory. The shared memory is accessed by a plurality of processing threads designated for pixel rendering. The processing threads seize and lock sub-screens tasks in an orderly manner and process the tasks to create the bit map for display on a screen. The tasks are created by dividing a display area having the vertex information superimposed thereon into M×N sub-screen tasks. Based on system profiling, M and N may be varied.

Abstract: A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, data frames are created from audio information by a vocoder and stored in a queue. Prior to storage, some of the data frames are eliminated, or dropped, and are not stored in the queue. In a receiver, data frames are generated from received signals and stored in a queue. Prior to storage in the receiver queue, some of the data frames are dropped. Data frames are dropped either at a single fixed rate, a dual fixed rate, or a variable rate, generally depending on a communication channel latency. By dropping data frames at the transmitter, the receiver, or both, voice latency due to data frame retransmissions is reduced.
