摘要： A system and method for performing threshold stamping are disclosed. First and second threshold values corresponding to first and second pixels may be retrieved from a threshold memory. A plurality of upscaled threshold values may optionally be computed based on the first threshold value and the second threshold value. An (upscaled) threshold value may be updated at each of one or more first register blocks. A binary pixel value may be computed based at least in part on the first updated threshold value. The first updated threshold value may be updated at each of one or more second register blocks. A downscaled threshold value may optionally be computed based on a plurality of second updated threshold values. The downscaled threshold value or second updated threshold value may be damped in a damping circuit, and the damped threshold value may be stored in the threshold memory.

摘要： A cross-crawl chair including a chair frame for supporting a headrest, chair back, chair seat, right and left arm supports, right and left leg supports, and four actuators for moving the supports. The chair also includes a control system which synchronizes the movement of the right arm actuator with the left leg actuator and the movement of the left arm actuator with the right leg actuator so as to provide an “arm and opposing leg” or cross-crawl motion. Further, the electro-mechanical control system controls a speed, a length of time, and a range of the cross-crawl motion.

摘要： Combined input scanner and output scanner has a scanning carriage adapted for scanning movement having a reading head secured thereto for scanning a document to produce a digital image and a printing head secured thereto for relative movement with respect to a copy sheet and electrically connected to the reading head for printing a digital image on a copy sheet. The reading head includes a solid state device with input reading elements and the printing head includes a solid state device with output printing elements which are securely comounted in the same plane to the same planar substrate.

摘要： A combined input scanner and output scanner has a frame assembly, a document transport to transport a document through the scanner in a path in a first direction and, a copy sheet transport to transport a copy sheet through the scanner a document registration means and a copy sheet registration means, the document registration gate including a cover pivotally mounted on the machine for movement between an open and closed position over the document transport path, said cover having at least one document registration gate adjacent its downstream end which extends into the document transport path to register the lead edge of a document when the cover is in the open position, the copy sheet registration means including at least one copy sheet registration gate in the copy sheet transport path to register the lead edge of a copy sheet when said cover is in the open position. The cover has a tab for removing the at least one copy sheet registration gate from the copy sheet transport when the cover is in the closed position over the document transport path.

摘要： A method and system for performing error diffusion is disclosed. An error value for a pixel may be received and used to determine one or more error diffusion values. The error diffusion values may be determined by performing bit shifting of the error value. Truncation of the error diffusion values may result in a difference between the error value and a sum of the error diffusion values. This difference may be compensated for by adding error compensation values to the error diffusion values to yield compensated error diffusion values. The compensated error diffusion values may then be diffused to appropriate destination pixels.
摘要翻译：公开了一种用于执行误差扩散的方法和系统。可以接收像素的误差值并用于确定一个或多个误差扩散值。可以通过执行误差值的位移位来确定误差扩散值。误差扩散值的截断可能导致误差值与误差扩散值之和的差异。可以通过将误差补偿值添加到误差扩散值来补偿该差异，以产生补偿的误差扩散值。然后可以将经补偿的误差扩散值扩散到适当的目标像素。
