Abstract: A continuous braid structure has one or more first braid sections, each having a respective single flat braid or a respective single tubular braid. A plurality of second braid sections each have at least two flat braids with a gap between them. The second braid sections alternate with the one or more first braid sections. The adjacent first and second braid sections are continuous with each other. A length of material extends through the respective gap of at least one of the one or more second braid sections, so the length of material crosses one or more times between a first side of the continuous braid and a second side of the continuous braid.

Abstract: A braider comprises a plurality of horngears. The horngears can be arranged for forming at least two closed paths for braiding. Each horngear has a driving gear and a hornplate. Each horngear can be selectably operated in a first mode, to rotate with the driving gear, and in a second mode, in which the driving gear rotates, but the hornplate does not. Bobbin carriers are positioned on some of the horngears. A track is configurable in: a first flat braiding mode with the carriers arranged on the horngears, so that there is one or more separate closed path for forming a first flat braid configuration; and a second flat braiding mode for forming a second flat braid configuration different from the first flat braid configuration. A switch is provided for changing a configuration of the track between the first and second flat braiding modes.

Abstract: An exemplary device implementation includes: a manager that is capable of monitoring a process for preparing a page for printing; and a print engine that is capable of printing the page after the process for preparing the page for printing is complete; wherein the device is adapted to temporally overlap the process for preparing the page for printing with preparation of the print engine for printing. An exemplary method implementation includes actions of: beginning processing of a page of a printing job; providing at least one command to a print engine responsive to at least one time remaining estimate for the processing of the page of the printing job prior to completion of the processing of the page of the printing job; and changing a state of the print engine responsive to the providing of the at least one command to the print engine.

Abstract: A braider has a track for guiding 4N bobbin carriers and 4N horngears, where N is an integer greater than one. The horngears each have four horns for forming at least two paths. The bobbin carriers are positioned on the horngears in a tubular braiding mode with the track and horngears configured to provide two paths intersecting each other, to form a tubular braid section. The bobbin carriers are positioned on the horngears in a flat braiding mode, with the track and horngears configured so that there are N separate closed paths that do not intersect each other, to form a flat braid section. The braider is switched between the tubular and flat braiding modes while N of the horngears are free of contact with the bobbin carriers, to form a continuous braid having at least one tubular braid section and at least one flat braid section.

Abstract: 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.

Abstract: A print unit prints pages of a print job in a different page order than the logical page order, but outputs the print job in a logical page order. A control system repetitively selects one or more portions of the print job from a memory device. Each of the one or more portions is selected out-of-logical page order for supply to the print unit to satisfy printing in the different page order. Each of the one or more portions when selected from the memory device, are temporarily stored in location(s) of a print-ready memory until no longer needed for supply to the print unit, at which time the control system releases the location(s) to be able to receive new data. “Memory out” conditions are also avoided by immediately releasing all objects associated with collated printing before completion of the collated print job, if memory is insufficient to complete the job.

Abstract: 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.

Abstract: 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.

Abstract: An imaging device and method provide a binding of complexity indicia to bands of a page being composed for video imaging. The indicia enable memory management tasks to be performed on the bands while the page is waiting in the page pipe to be imaged. Advantageously, the memory management tasks are performed without waiting for any already composed page to finish imaging. Accordingly, page throughput of a multi-page print job is improved. In one embodiment, the indicia includes at least one data element that is indicative of the band being safe for being acted upon by the memory management tasks. In an alternate embodiment, the indicia includes a data element that is indicative of a complexity of the band for being video imaged, and a further data element that is indicative of an incremental complexity of the band relative to a given memory management task that may be performed.

Abstract: An imaging device and method provide memory management tasks on page data in memory upon detecting a status of the memory during the composing of a current page and without waiting for an already composed page to finish imaging. As such, page throughput of a multi-page print job is improved. The status of the memory detected includes a memory allocation fault and a free memory status threshold. The memory management tasks include compressing the data in the memory, relocating the data, and/or compressing and relocating the data. Optionally, the compressing and relocating includes using a memory fragmentation avoidance technique. The data in the memory on which the memory management tasks are performed includes raster patches, video bands, vector bands, fonts, and patterns either on the page currently being composed for imaging and/or on pages that are already composed and waiting to be imaged.
