    • Methods of guard-banding, methods of dynamic guard-banding, and related apparatus for real time image-data processing are described. In one embodiment, at least one image-processing pipeline variance is measured. Responsive to measuring the image-processing pipeline variance, a guard band is imposed around a processing parameter of the image-processing pipeline. In another embodiment, a first parameter relating to processing time of a predetermined amount of data through an image-processing pipeline is determined. A second parameter relating to processing time of the predetermined amount of data through the image-processing pipeline is determined. The second parameter is related to the first parameter. The first and second parameters are compared, and responsive thereto, a guard band is imposed on at least a portion of the processing which takes place in the image-processing pipeline. In preferred embodiments, the guard bands are adjustable dynamically or on-the-fly.

    • An imaging device and method enable the freeing of memory during a punt (print overrun) avoidance operation and during a duplexing operation for enhanced page throughput. Specifically, if a first race condition threshold is met, being indicative of an estimated need to pre-rasterize a band from a page of image data for punt avoidance, and if after pre-rasterization it is determined pre-rasterization is not actually needed for punt avoidance, then the pre-rasterized band is evaluated relative to its display list for memory savings purposes for improved page throughput performance. Similarly, if a duplex condition threshold is met, being indicative of a band being part of a first side of a duplex page being processed and of an estimated need to save memory for processing of the second side of the duplex page, then the band is pre-rasterized and evaluated relative to its display list for memory savings purposes for improved duplex page throughput performance. If neither the race condition threshold nor duplex condition threshold is met, but an increased general memory savings condition threshold is met for the band, then the band is pre-rasterized for memory savings purposes.

    • Methods of providing page protection in digital printing systems having multiple output devices are described. In one embodiment, first and second output devices are provided and have different time constraints for processing predetermined amounts of data which will ultimately be printed on a print medium. One of the time constraints is selected to provide a selected time constraint, and at least one predetermined amount of data is tested against the selected time constraint to determine whether the selected time constraint is satisfied. If the selected time constraint is not satisfied, the predetermined amount of data is transformed into a state which is more likely to satisfy the selected time constraint. In another embodiment, a first processing time constraint of a first output device is determined. The first processing time constraint impacts the manner in which a predetermined amount of data is processed into a printed image. A second processing time constraint of a second output device is determined. The second processing time constraint impacts the manner in which the predetermined amount of data is processed into a printed image. The first and second processing time constraints are compared and responsive to the comparison, the processing time constraint having a lesser magnitude is selected to provide a selected processing time constraint.

    • An imaging device and method optimize memory usage during a print overrun avoidance operation by employing selected compression schemes upon page bands while ensuring that required decompression times of the bands are met for subsequent rendering purposes. A preferred method includes compressing a band from a page of image data and, if an estimated decompression time for the compressed band does not satisfy a race-the-laser threshold for subsequent video imaging, then decompressing the band and measuring an actual decompression time. If the actual decompression time satisfies the race-the-laser threshold, then the method includes keeping the compressed band for subsequent video imaging. On the other hand, if the actual decompression time does not satisfy the race-the-laser threshold, then the band is re-compressed using an alternate compression scheme and re-evaluated similar to the originally compressed band to determine whether the recompressed band's decompression time will satisfy the race-the-laser threshold.
    • 成像设备和方法通过在页面频带上采用选定的压缩方案来优化在打印超限避免操作期间的存储器使用,同时确保满足所需频带的解压缩时间以用于后续渲染目的。 优选的方法包括从图像数据的页面压缩频带,并且如果压缩频带的估计的解压缩时间不满足后续视频成像的激光激光阈值,则解压缩频带并测量实际的解压缩时间。 如果实际的解压缩时间满足激光激光阈值,则该方法包括保持压缩频带用于随后的视频成像。 另一方面,如果实际的解压缩时间不满足竞赛激光阈值,则使用替代压缩方案重新压缩频带,并且重新评估类似于原始压缩频带的频带,以确定再压缩频带的解压缩 时间将满足激光门槛。

    • A machine for manufacturing triaxial fabrics, primarily of the type disclosed and claimed in U.S. Pat. No. Re. 28,155, comprises a vertically oriented warp yarn supply means based upon a horizontally disposed rotating creel, on which is preferably mounted a plurality of beams each supplying a plurality of warp yarn ends. Guide holders travelling on a cam-shaped track compensate for warp yarn path length changes so as to maintain path lengths from creel to weaving means relatively constant independent of angular position of an individual warp yarn in the course of the weaving process. Preferably, a multiplicity of such guides are combined on a single trolley carrier several of which are mounted at spaced intervals on the cam-shaped track, the movement of which is co-ordinated with the rotational movement of the warp yarn supply creel. Tension is maintained in the warp yarn supply by a multiplicity of individual roller guides mounted on spring arms which bend slightly to maintain tension in each warp yarn as the weaving shed is made and unmade.
