    摘要: Systems and methods of storing previously transmitted data and using it to reduce bandwidth usage and accelerate future communications are described. By using algorithms to identify long compression history matches, a network device may improve compression efficiently and speed. A network device may also use application specific parsing to improve the length and number of compression history matches. Further, by sharing compression histories, compression history indexes and caches across multiple devices, devices can utilize data previously transmitted to other devices to compress network traffic. Any combination of the systems and methods may be used to efficiently find long matches to stored data, synchronize the storage of previously sent data, and share previously sent data among one or more other devices.

    摘要: A number of pixels are received at a pixel rate that corresponds to a lower data transfer rate. The received pixels are delivered for display on a display device, over an interface that operates at a higher data transfer rate. These pixels are delivered as part of a stream that includes one or more codes that have been inserted between each adjacent pair of pixels so that the pixels in the stream are still delivered at the pixel rate. Other embodiments are also described and claimed.

    摘要: Conventional receiver architectures are based on either frequency/phase tracking or oversampling. Both receiver types typically employ sensitive analog circuits, which create noise, consume power and utilize valuable space in their implementation. The invention adopts a novel approach to phase/frequency tracking that utilizes the edges or zero crossings of the input data waveform to effectively track the remote transmitter clock phase/frequency. This methodology minimizes the use of analog circuitry, thereby reducing the noise domain and the substrate space required for implementation of a tracking device.

    摘要: A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a base having a pair of tangential jet nozzles for generating the self-driven force for the centrifuge. Connected to the base is a centrifuge shell which defines a hollow interior space. A hollow rotor hub having a central axis of rotation is assembled to the base and extends through the hollow interior space. A support plate is positioned within the hollow interior space and, in cooperation with the rotor hub, defines an annular flow exit opening for the circulating liquid. Positioned within the hollow interior space is a separation vane module which is constructed and arranged so as to extend around the rotor hub and positioned so as to be supported by the support plate. The separation vane module includes a plurality of axially-extending and spaced-apart separation vanes.
