    • A method and system for determining whether a digitized page is intended to be viewed in a first, portrait orientation or in a second, landscape orientation that is rotated with respect to the first orientation. The method includes a first step of examining an image of the digitized page on an image scanline by image scanline basis to detect occurences of graphic elements having heigths, widths, and aspect ratios that are within predetermined limits. The range-defining thresholds are determined to correspond to the expected dimensions of "character-sized" graphic objects. For each detected occurrence, the method determines a spatial relationship of the detected occurrence to other adjacently disposed objects. The method further operates, in accordance with a plurality of the determined spatial relationships, to declare the digitized page to have one of the first format and the second format. The step of determining operates to ascertain an amount of a spatial separation between the detected occurrence and an adjacent object on the same scanline and to an adjacent object on a succeeding scanline. The step of examining includes a step of forming, for each scanline, a list of spans of image pixels each having a predetermined value, and the step of determining a spatial relationship determines, for each span of the list, a distance to a next span on the same scanline, and for a last span of an image object, a distance to a first open span on a succeeding scanline. Each image object has an associated bounding box and a clear pedestal having a width that is a function of the width of the bounding box. The distance to the first span on a succeeding scanline defines a height of the pedestal.

    • A method for compressing and expanding source image representative data is disclosed. The method for compressing rasterized source image representative data comprises the following steps. The rasterized source image representative data is partitioned into a first plurality of sections each containing only blank lines, and a second plurality of sections each containing non-blank image representative data. Each section in the first plurality of sections is represented by a respective blank-line codeword. Each section in the second plurality of sections is further partitioned into a plurality of blocks, each having L lines of P pixels and a pattern. For each partitioned block, one of a plurality V of code vectors, each having L lines of P pixels and a predetermined pattern which most closely matches the pattern of the partitioned block, is selected. Each partitioned block is represented by a respective non-blank codeword representing the selected one of the plurality of code vectors. The compressed image, thus, is represented by successive codewords representing either blank lines or code vectors. The method for expanding the compressed image represented by the successive codewords comprises the following steps. Blank lines are inserted into rasterized reproduced image representative data in response to blank-line codewords. The pattern of the code vector represented by each non-blank codeword is inserted into the rasterized reproduced image representative data in response to each non-blank codeword. A rasterized reproduced image results from this expansion.
    • 公开了一种用于压缩和扩展源图像代表数据的方法。 用于压缩光栅化源图像代表数据的方法包括以下步骤。 光栅化源图像代表数据被分割成仅包含空白行的第一多个部分,以及每个包含非空白图像代表数据的第二多个部分。 第一多个部分中的每个部分由相应的空行代码字表示。 第二多个部分中的每个部分进一步分割成多个块,每个块具有L个P个像素和一个图案。 对于每个分区块,选择多个V个代码矢量中的一个,每个代码矢量具有L个P个像素行和与该分割块的图案最匹配的预定图案。 每个分区块由表示多个代码矢量中选择的一个代码矢量的相应的非空白代码字表示。 因此,压缩图像由表示空白行或代码矢量的连续代码字表示。 用于扩展由连续码字表示的压缩图像的方法包括以下步骤。 响应于空行代码字,空白行被插入到光栅化的再现图像代表数据中。 响应于每个非空白码字,将由每个非空白码字表示的码矢量的图案插入到光栅化再现图像代表数据中。 光栅化的再现图像来自此扩展。

    • Disclosed are methods and apparatus for interfacing a central processor (12) (CP) and a IO controller (30) (IOC) to a main memory (40). A CP and a IO write buffer each include a pair of memory input data registers, located in a pair of Memory Data Unit (MDU) integrated circuits (38a, 38b), and also two memory address registers, a previous memory address register, and an address comparator, located in a Memory Address Unit (MAU) (36). These registers, in conjunction with associated control logic, are used to buffer CP and IO write addresses and data to the main memory. If both address registers have a pending write, the last loaded address register is checked for a match against the current write address using the previous address register and the comparator. A match results in the combination of the previous write data and the current write data into one pending write, using write merge circuitry within the MDUs. IO read operations are performed by first loading the MDU read data registers with read data from memory locations specified by a quad-word aligned address in the first IO address register, followed by an incremented quad-word aligned address in the second IO address register. The transfer is then begun and all incoming IO read addresses are checked for a current quad-word compare. If an incoming quad-word aligned IO read address is not equal to the content of the IO previous address register, a memory read request is generated using the incremented address, and the MDU read data registers are advanced. A feature of this invention is that no specific addresses are used, and a knowledge of a transfer width (byte, word, etc.) is not required to determine memory operation types.
    • 公开了用于将中央处理器(12)(CP)和IO控制器(30)(IOC)连接到主存储器(40)的方法和装置。 CP和IO写缓冲器各自包括位于一对存储器数据单元(MDU)集成电路(38a,38b)中的一对存储器输入数据寄存器,以及两个存储器地址寄存器,前一存储器地址寄存器和 地址比较器,位于存储器地址单元(MAU)(36)中。 这些寄存器结合相关的控制逻辑,用于将CP和IO写入地址和数据缓冲到主存储器。 如果两个地址寄存器都有待处理的写入,则使用先前的地址寄存器和比较器,检查最后加载的地址寄存器与当前写入地址的匹配。 使用MDU内的写入合并电路,匹配导致先前的写入数据和当前的写入数据组合成一个挂起的写入。 通过首先将第一个IO地址寄存器中的四字对齐地址指定的存储单元的读取数据加载到MDU读取数据寄存器中,然后在第二个IO地址寄存器中加载四字对齐的地址,从而执行IO读取操作。 然后开始传输,并检查所有输入的IO读取地址以获得当前的四字比较。 如果输入的四字对齐IO读地址不等于IO先前地址寄存器的内容,则使用增加的地址生成存储器读请求,并且MDU读数据寄存器被提前。 本发明的一个特征是没有使用特定的地址,并且不需要知道传输宽度(字节,字等)来确定存储器操作类型。

    • Apparatus and method for communicating between a plurality of devices on an electrical network (bus) that supports the Small Computer Systems Interface (SCSI) standard as described in American National Standards Institute (ANSI) SCSI-1 Specification X3T9.2 Rev. 17B. To communicate via the SCSI bus, bus controlling circuitry in a first device and counterpart circuitry in a second coupled device must conform to the SCSI standard which allows a particular SCSI bus to be one of two electrically different but functionally equivalent formats: single-ended or differential. To permit a device to communicate through either a single-ended or a differential SCSI bus, small adapter cards are used with a compatible SCSI bus controller board to communicate over either format SCSI bus. The adapter cards come in two different types to allow single-ended or differential communication, respectively. The adapter cards are an inexpensive and easy way to adapt a device's SCSI bus control circuitry selectively to either a single-ended or differential SCSI bus.

    • A method enables a dithered representation of an image to be converted to a continuous tone representation of the image. This undithering method compares the regions of dithered representation with sections of dither patterns to determine an appropriate continuous tone representation from which the dithered image could have resulted. When the continuous tone representation is found the region is converted into a continuous tone representation. This procedure may be spatially iterated on a pixel by pixel basis until all of the initial representation of the image is converted into a continuous tone representation. The procedure may also be modified to account for line art. Furthermore, the procedure may be applied to produce adjustments in the size of the picture including miniaturizations and enlargements of the original image. In accordance with this application, dithered portions of the original image are redithered in a manner to produce an alternative size output image. Similarly line art portions of the original image are treated as grey scale values and redithered to produce the alternative size representations of the line art.

    • A connector provides alignment between an electro-optic device and an optical fiber of an optical fiber cable. The connector employs a holding member for removably retaining the working end of the optical fiber and an electro-optic device aligned with each other for communication therebetween. The holding member has a cavity in one side wall in which the device is removably retained, and a channel, from an opposite side wall to the base of the cavity, in which the optical fiber is positioned. The channel is of varying diameter, and includes a cavity facing end having a diameter which is sufficient to accommodate the optical fiber but which is smaller than the outer diameter optical fiber cable. The cavity facing end of the channel ensures alignment of the optical fiber with the device retained in the cavity. A clamp member comprising spreadable prongs secures the optical fiber cable in position in the larger diameter region of the channel of the holding member. The clamp member and holding member cooperate together to form a single connector unit which is easily accommodated on a circuit board and secureable thereto.
