Abstract: A print data processing pipeline (15) for use in a color electrophotographic printer optimizes print quality and minimizes memory usage by separately processing lossy and lossless print data. Lossy print data may include print data for images and lossless print data may include print data for text, line art, and graphics. Partitioning print data into lossy and lossless elements allows application of the print data compression operations optimized for each type of print data. High compression ratios can be achieved on lossy print data by applying visually lossless compression operations designed for the lossy print data. In addition, high compression ratios can be achieved on the lossless print data by applying lossless compression operations designed for the lossless print data. A merge unit (128) combines the lossy and lossless print data streams after decompression to reconstruct the original image using merge data. The merge data is generated in an image processing operation (1) which accounts for the different transparency modes of the page description language print data so that the correct foreground and background placement of objects is maintained. Placement of the color space conversion operation (12) and the halftone operation (14) relative to the merge operation (14), further optimizes the print quality while minimizing memory usage. The print data processing pipeline (15) includes a direct memory access controller (122) which has the capability to allow print data to be selectively directed to the lossy (126) or lossless (127) compressor/decompressor, the color space converter (125), or the merge unit (128). Feedback paths within the print data processing pipeline (15) allow the results of the various operations performed to be returned to the direct memory access controller (122) for further processing or storage in system memory (2,6). Bypass paths in the color space converter (125) and halftone unit (130) allow print data to be selectively directed around these operations. These capabilities allow configuration of the print data processing pipeline (15) to perform a multitude of permutations of print data processing operations optimized for the print data. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To obtain a detection apparatus by which an object in front of a vehicle on a road, especially on a curve road, can be detected in an early stage by computing the approximate line of the connection of all first-scene-originated density edge points and second-scene- originated density edge points on road-system coordinates. SOLUTION: A first scene which is photographed by a first camera 16b contains a precedent vehicle and the like on a vehicle where the apparatus is mounted running lane at a short distance of 10 to 30m, and its resolution is high. In second scenes which are photographed by a second camera 26b and a third camera 36b , the resolution of a road surface and a vehicle at long distances of 30 to 60m and 60 to 90m is high. Positions of density edge points on both photographed scene screens are converted, by coordinate conversion means 100 to 300, into an identical road-system coordinate position in which the horizontal projection line of respective vehicle front and rear axles is regarded as one axle, and a density edge point distribution on the top view of a road surface is obtained.  A line which approximates the connection of all density edge points originated from both scenes of road-system coordinates is computed 100, and the approximate line of an on-road white line from a short distance up to a long distance is obtained. When the approximate line is used as a reference to set a search region in order to detect a preceding vehicle, an object in front of the vehicle on a road, especially on a curve road, can be detected in an early stage.

Abstract: A metal expansion dowel is made up of an axially elongated cylindrically shaped expansion sleeve and an expansion element formed monolithically with the sleeve. The expansion sleeve has a leading end and a trailing end. The sleeve has an opening with the opposite edge surfaces extending in the axial direction converging toward the leading end. The expansion element is located in the opening and is secured to the sleeve by a separable web. The expansion element is wedge-shaped and narrows in the leading end direction. An inwardly projecting stop is formed in the expansion element. When an axial force is directed toward the leading end against the stop, the web is separated from the sleeve and the expansion element is displaced axially toward the leading end of the sleeve moving along the opposite edge surfaces of the opening and widening the sleeve. Due to the converging arrangement of the opposite edge surfaces of the recess, the dowel has a post-expansion characteristic during subsequent axial loading of the expansion sleeve after it is anchored in place.

Abstract: A method of determining the success or failure of the press fitting a workpiece into an object member having a contact end by a linearly-driven plunger is disclosed. In a predetermined stroke range RM of the plunger press fitting the workpiece, thrust information S1 and position information S2 are acquired. The position where the ratio of change of the thrust information S1 with respect to the position information S2 exceeds a predetermined value is detected as an almost press fit end position LLP. The success or failure of the press fitting work is determined according to whether the thrust information S1 is included in a predetermined range of a section from a predetermined determination start position LLH to a determination end position LLQ during the press fitting work. The determination end position LLQ is determined based on the almost press fit end position LLP. The press fitting force is determined at a position nearest to the contact end, thereby making it possible to determine the success or failure of the press fitting work accurately. <IMAGE>
