    摘要： Already stored uncompressed raster data are selectively compressed before any new raster data can be processed and stored. Both compressed and uncompressed raster data is preferably stored in the same size blocks, and the Raster Objects are preferably divided at Render Swath boundaries. Assuming that the Raster Object data has been or will be compressed by means of a known dither matrix, that dither matrix is used in the compression process to eliminate all but the data essential to reconstruct the dithered image, and the pixels of the original image are preferably successively processed along a predetermined scan path and the resultant linear pixel array is divided into successive runs which may each be encoded such that when those encoded runs are assembled into a replica of the original image and both the original image and the replica image are dithered with the same predetermined dither matrix, the dithered replica image is identical to the dithered original image. The dither-matrix based compression of the raster data is preferably followed by Golomb Rice compression.

    摘要： A system and method for affecting the behavior of the transmitting UART that, in turn, results in an internal state change in the receiving UART. The present invention, upon detecting a PPP packet, flow controls the line, causing the transmitting UART to force a marking condition (that is, all ones) or idle state. This idle state enables the receiving UART to exit sampling mode and receive the remaining incoming data within the PPP packet in byte mode. The receiving UART, when operating in byte mode, automatically accounts for slew.

The micromirror control system also includes a micromirror, communicatively coupled to the stopper plate on a bottom side, and including a reflective top side configured to reflect light. Rotation of the stopper plate about the axis into contact with the micromirror is configured to adjust an orientation of the micromirror. In one aspect, the micromirror control system also includes an actuating device, communicatively coupled to the stopper plate, configured to control the rotation of the stopper plate about the axis. The advantages of the present invention include the ability to finely control translation and rotation of a discretely controlled micromirror.

    摘要： A system and method for accounting for clock slew during autobauding. Upon identifying an AT command and the baud rate of the incoming data stream, the present invention accounts for clock slew in one of two ways, depending upon the baud rate of the incoming data stream. If the baud rate of the incoming data stream is 9600 or greater, the present invention accounts for slew by utilizing a feature associated with ASCII characters and RS-232 protocol, that is the stop bit being nicely framed on both sides by spaces. This feature is used to determine whether negative or positive clock slew exists. If negative clock slew exists and it is determined that negative clock slew falls within a certain threshold, a sample is skipped. If positive clock slew exists and falls within a certain threshold, positive clock slew is converted to negative clock slew by taking an extra sample. Clock slew is accounted for by reconstructing bits from an old sample and a new sample, based on the calculated slew value, to obtain an actual sample that eliminates deleterious effects of clock slew. When the baud rate of the incoming data stream is less than 9600, the present invention accounts for clock slew by taking a middle group of 8 samples from the start bit when multiple groups of 8 samples per bit exist. This is accomplished by searching for the next start bit. Once the next start bit is found, determining which group of 8 samples is a middle sample.

    摘要： A bi-level dithered image is compressed using knowledge of the particular dither matrix used to generate the dithered image from an original high resolution grey-scale image. A lower resolution grey-scale image is substituted for the original high resolution grey-scale image (which may be further compressed with known compression techniques), such that after the two images (after any required decompression) have been dithered by that same dither matrix, the resultant dithered images are the same (lossless compression) or substantially the same (lossy compression). In a preferred embodiment, the lower resolution encoded multi-tone image is based on variable sized blocks of pixels, with the dither matrix being used to determine an optimal size and intensity of each block in the encoded image such that when the lower resolution image is dithered, it is indistinguishable from the dithered original image. Since the encoded image is in effect merely a lower resolution version of the original image with the "blue" noise introduced by the dithering process removed, it can be further compressed by a conventional compression algorithm (such as the "JPEG" algorithm for lossy compression of continuous tone images or the "Ziv/Lempel" algorithm for lossless compression of digital data).
