Abstract: A solid ink feed system for a printer includes a longitudinal feed channel having a feed direction, and an insertion key plate having a key plate opening through it to provide access in an insertion direction into the feed channel. The insertion direction is different from the feed direction. The key plate opening has an insertion opening perimeter that includes two lateral opening perimeter segments and a transverse opening perimeter segment. The transverse opening perimeter segment intersects at least one of the lateral opening perimeter segments at an angle other than 180°. The insertion opening perimeter includes a first nonlinear key element on one lateral perimeter segment, a second nonlinear key element on a second lateral perimeter segment, and a third nonlinear key element on the transverse perimeter segment. An ink stick for the solid ink feed system includes an ink stick body having a perimeter shape that substantially matches the insertion opening perimeter.

Abstract: Techniques that allow the operations of a program to be intercepted and intervened with are known. These techniques are restricted by the same limited view of the program's data that is currently available at a base level of an object or method. Some aspects need access to more information about the program's data of one or more objects than is available at the base level. An aspect of aspect-oriented programming systems, methods and environments examines the results of a computation at one stage. That aspect affects only subsequent stages of the computation, so that no circularity exists. Custom flow analyses, whether local or global, can also be performed at each stage to propagate non-local information. “Macro” style programming can be reduced or avoided, as programming can be facilitated in terms of manipulating the results of various computational stages instead of in terms of manipulating blocks of code.

Abstract: An imager circuit includes an array of pixels, each pixel including a sensor (photodiode) connected to an input terminal of a comparator. The comparators of each pixel row have output terminals connected to a latch. A counter generates a sequence of digital values that are transmitted to a digital-to-analog converter (DAC) and to the latch of each row. The DAC generates a ramp voltage that is transmitted to a second input terminal of each pixel's comparator. The comparators of a selected pixel column are enabled to generate output signals when the ramp voltage equals each pixel's voltage, causing the associated latches to capture the current digital values. The comparators are formed such that each pixel row shares a cascode mirror circuit that detects differential currents in data line pairs connected to each pixel in that row.

Abstract: A method and a system for separating an image signal into a set of image planes are disclosed. The system comprises a way to perform resolution conversion from low resolution to high resolution binary images either for synthetic or scanned imagery by using template matching with pattern replacement. More specifically, the invention applies resolution conversion to the selector plane of mixed raster content images. For selector planes in which edges are encoded (vs. region classification), template matching/pattern replacement works well, and does not affect halftoned regions, as they are not encoded in this image.

Abstract: Disclosed are an image processing device and an image processing method capable of generating a high-resolution color image of a fine gray scale from image data of a small information amount by using a small memory capacity. A character graphics image of high resolution generated by a character rasterizing block is converted by a conversion block to image data in which color information of one color is assigned per group of pixels, and tag information indicating whether the color information is used or not is added with respect to the multiple pixels to which the color information is assigned. By the tag information, while maintaining the high resolution, a fine gray scale can be assured. An image decoding block which has received such image data decodes the image data into a color image of output resolution by assigning the color information to the position indicated by the tag information.

Abstract: A system and method for the halftoning of gray scale images by utilizing a pixel-by-pixel comparison of the image against an anisotropic stochastic screen is disclosed.

Abstract: An image processing method generates a halftone image by forming a halftone dot represented by a set of one or plural output dots corresponding to an intensity of an input image signal while making a part of the dots constituting the halftone dot to be an actual non-output dot so as to reduce an amount of a coloring material of a halftone-dot portion. The image processing method includes holding in a predetermined storage medium halftone-dot profile data for forming the halftone dot corresponding to the intensity of the image signal and gap-size profile data representing a size of a set of the non-output dot; and generating the halftone dot comprising a gap having a size based on the gap-size profile data, a size of the halftone dot being based on the halftone-dot profile data.

Abstract: A method electronically modifies a compiled executable file, the compiled executable file including a plurality of data elements by compiling source code to created a compiled executable file having a first data structure corresponding to the source code such that the first data structure is realized each time the source code is compiled; rearranging locations of a predetermined number of data elements within the first compiled executable file to create a compiled executable file having a second data structure; and editing address data within the compiled executable file in accordance with the rearranged locations to generate a compiled executable file having a unique second data structure that functions a same way as a compiled executable file having a first data structure. This unique second data structure creates an essentially indelible mark on the software file while maintaining its functionality.

Abstract: A media separator, that cooperates with a media pick to form a nip in a feed path of a media handling apparatus, supports a separation pad that includes first and second friction regions for movement relative to the media separator, against a bias force, in a feed direction of a sheet of media through the nip. The first and second friction regions selectively engage the sheet of media passing through the nip with a retard/separation force determined by the bias force, to retard and control a feeding operation of the sheet of media through the nip, and to feed plural sheets of media through the nip one at a time.

Abstract: For an automatic image diagnosis, toned images or residual toner existing on the photoconductive surface of a photoreceptor may be scanned with light energy provided by the raster scanning system. The light energy, which may be reflected from the photoreceptor surface, may be disturbed due to scattering/absorption in toned or damaged surface regions. The light energy may be directed to image sensors to obtain a spatial image map of the photoreceptor surface in conjunction with pixel clock information present for the raster scanning system. The evaluation may be made based on the spatial image map. Diagnostic and maintenance may then be applied to correct the defect and/or adjust a tone level for a latent image formed on the photoreceptor surface.
