摘要： A character generator with multidirectional scan and variable line and character (or symbol) size capability. Universality is implemented by producing a serial binary stram which can be used to print or display in any of eight combinations of scan direction and progression, that is, for scan direction left to right, or vice versa, progressing up or down, or scan direction top to bottom or vice versa, progressing left or right. In formatting the serial binary stream, a font is accessed (for basic symbol definition), which selectively provides for orthogonal scans of the symbol definitions. Variable line size is implemented by terminating a symbol row (or line) based on a predetermined size criteria regardless of the comparable font dimension and "filling" up to the line size to the extent the corresponding font dimension is less than the predetermined size criteria. Variable character (or symbol) size is implemented by independently multiplying the effect of a symbol definition by selected (integral) factors, in orthogonal directions. The general architecture includes a font table (for symbol definition), an address/escape (A/E) table, defining symbol size for comparison with line size parameters, a character position escape (CPE) table to define a leading character or symbol on each line and a page buffer (PB) memory defining the characters (symbols) in the document and their relationship with other characters (symbols). Access to the CPE table allows access to the PB, from there to the A/E table and from there to the font allows extraction of selected and appropriate portions of the symbol definition to make up the binary system.
摘要翻译：具有多向扫描和可变行和字符（或符号）大小功能的字符生成器。普遍性是通过产生串行二进制跨层实现的，可以用于打印或显示扫描方向和进展的八种组合中的任何一种，即扫描方向从左到右，反之亦然，向上或向下或扫描方向从上到下，反之亦然，向左或向右进行。在格式化串行二进制流时，访问字体（用于基本符号定义），其选择性地提供符号定义的正交扫描。可变线尺寸通过基于预定尺寸标准终止符号行（或线）而实现，而不管可比较的字体尺寸如何，并且在相应的字体尺寸小于预定尺寸标准的范围内“填充”直到线尺寸。通过在正交方向上独立地将符号定义的效果乘以所选（积分）因子来实现可变字符（或符号）大小。一般架构包括字体表（用于符号定义），地址/转义（A / E）表，定义用于与行大小参数进行比较的符号大小，用于定义前导字符或符号的字符位置转义（CPE）表每个行和页面缓冲区（PB）存储器定义文档中的字符（符号）及其与其他字符（符号）的关系。访问CPE表允许访问PB，从那里到A / E表，从那里到字体允许提取符号定义的选定和适当的部分，以构成二进制系统。

摘要： Resource master and slave combinations operating from separate local clocks asynchronously even though there may be wide speed variations among the devices, eliminating the need to synchronize the trailing edges of generated control signals with the local clock so as to free access to the resource as soon as possible without introducing timing or logic hazards.

摘要： A detoxification process for rendering three-dimensional objects formed by solid freeform fabrication techniques biocompatible for use in long-term dermal contact applications. The process nullifies cytotoxins normally present in objects formed by solid freeform fabrication techniques rendering such techniques as viable for the production of biocompatible devices such as stents, artery valve components, bone implant supports, pacemaker shells, surgical tools, and the like. In one embodiment, a custom hearing aid shell is produced by stereolithography from an acrylate photopolymer resin that was detoxified for long-term dermal contact application. The detoxification process makes three-dimensional objects created by solid freeform fabrication techniques available for products requiring biocompatibility.

摘要： An output interface allows a user circuit to access data for multiple objects in an interleaved fashion. Status information is provided to guarantee data availability before each transfer sequence is started. An identifier is provided for each object. Each identifier, after data transfer has ended, may be subsequently reused to identify a different object. The interface provides the ability to retrieve all data in an object or to cancel the object before reaching the end and discarding the unretrieved data. The objects are provided to the appropriate processing mechanisms within the printer to implement a printing task. These objects correspond to images and text to be printed on a page. Object data is temporarily stored in limited data memory of the memory system and object headers are stored in header memory before transfer via the output interface. Each object to be printed has an object header and may, or may not, have associated object data.

摘要： The present invention includes a method of transferring data when some of the data is masked. A mask table is provided to a storage device where it is duplicated and stored with the duplicate. The duplicate data is compared to the original data for a data protection function. A mask index counter and mask bit counter maintain provide values for specific data that are to be processed. The counters are programmable so that if a transfer error occurs, counter values for the next data after the previously transferred good data is calculated and loaded therein. The present invention also has the capability not to transfer the last requested sector if that sector is masked. The present invention evaluates whether a stop count value equals a stop threshold value when a sector is identified as being masked. The stop count value is incremented for each sector that is read from the first storage device, regardless of whether that sector is to be transferred or masked. The stop threshold value is the total number of sectors to be transferred. If the stop count value equals the stop threshold value and the sector is masked (or not), a flag is generated to stop the transfer of that last masked sector.
摘要翻译：本发明包括当一些数据被屏蔽时传送数据的方法。掩模台被提供给存储设备，在该存储设备中它被复制并与副本一起存储。将重复数据与数据保护功能的原始数据进行比较。掩码索引计数器和掩码位计数器维护为要处理的特定数据提供值。计数器是可编程的，以便如果发生传输错误，则计算并加载先前传输好的数据之后的下一个数据的计数器值。如果该扇区被屏蔽，本发明还具有不传送最后请求扇区的能力。本发明评估当扇区被识别为被屏蔽时，停止计数值是否等于停止阈值。对于从第一存储设备读取的每个扇区，停止计数值递增，而不管该扇区是传输还是被屏蔽。停止阈值是要传送的扇区总数。如果停止计数值等于停止阈值并且扇区被屏蔽（否则），则生成标志以停止该最后一个屏蔽扇区的传送。

摘要： Clipping individual rows or columns of pels from patterns stored as pels is accomplished by passing quads of pels through a clipper before rotation is effected. Integral numbers of quads are clipped by skipping their address when reading from the pattern store or inhibiting their transfer. This permits more detailed pages to be composed for printing.

摘要： A method and apparatus for signal phase alignment. A pulse is produced and a reference clock signal having a first frequency with one or more clock edges is produced. An alignment clock signal is generated having the first frequency aligned with the pulse. The first frequency of the alignment clock signal is then realigned with the pulse. The alignment clock signal is generated using the pulse and aligning one of the clock edges of the reference clock signal with the pulse edge. The alignment clock signal is realigned using a plurality of delayed clock signals based on the reference clock signal. Each of the delayed clock signals has one or more edges. The plurality of delayed clock signals are latched based on the pulse and the delayed clock signal having an edge nearest to the pulse is selected.

摘要： Priority levels and bump values are assigned to requestors for access to a system resource. When access requests are received, arbitration of the requests is made in accordance with the assigned priorities, bump values, and the received access requests. If a high priority level access request is granted, then the same request will be held off for a successive number of requests as set by the bump values. In cases where the access is required for more than one request/grant cycle, the priority level access can be retained as long as required.
