Abstract: A color sensor monitors the output of a color producing process and produces a signal representative of a color produced by the color producing process. The signal can be used as feedback signal to control the process. Occasionally, the color sensor signal includes a component representing a transient error. A system model of the color producing process is used to predict reasonable sensor signals. A comparison of the sensor signal with the predicted sensor signals is used to determine if the sensor signal is reasonable. If the sensor signal is unreasonable, a substitute signal is used as the feedback signal to the control process. The substitute signal can be a predicted sensor signal or a signal based on historical system performance data.

Abstract: An optical waveguide element capable of being coupled with optical fibers at high coupling efficiency is to be provided. Also an optical waveguide element manufacturing method permitting accurate production of such optical waveguide elements is to be provided. The optical waveguide element is provided with a buffer layer formed over a monocrystalline substrate and an optical waveguide layer formed over the buffer layer, and a recess is formed in the buffer layer along the lengthwise direction of the monocrystalline substrate. The optical waveguide layer is provided to fit into this recess to form a channel optical waveguide. Over the upper face of the optical waveguide layer on the light incidence side and the light emission side, a cladding layer whose refractive index is smaller than that of the optical waveguide layer and whose thickness increases towards the end face(s) in a flared shape is provided in the same width as that of the monocrystalline substrate.

Abstract: A xerographic apparatus, a printer, a printer server, and the like processes wavelet domain image data and includes means for receiving the wavelet domain image data representative of an input digital image. The wavelet domain image data may be formatted as a JPEG 2000 compressed file or other wavelet domain file including N levels of wavelet decompositions. An M-level extractor extracts an Mth level wavelet decomposition from the wavelet domain image data where M is <N. The extracted Mth level wavelet decomposition is a low resolution representation of the input digital image. An image enhancement system receives the extracted Mth level wavelet decomposition and derives an enhancement process such as a tone reproduction curve, a sharpness filter, and the like from the extracted Mth level wavelet decomposition. The enhancement process is used to enhance a higher resolution representation of the digital input image.

Abstract: A method of constructing a halftone screen includes selecting a frequency and screen angle of interest. A subcell having spatial vectors which satisfy the selected frequency and screen angle of interest is identified. A supercell comprising an array of the subcells is formed. An integer relationship potentially having numerous solutions exists between the supercell and the subcell. The integer relationship is solved for values of the integers and then tested against the values for the subcell spatial vectors. Although the solution may in some cases be the null set, in many cases there will be numerous solutions. Each resulting solution, if any, is then tested according to any additional constraints or tolerances specified for the particular halftone screen. If any of the resulting supercell solutions satisfies the tests, that supercell may be used to create a halftone screen.

Abstract: Epidemic-style update communications facilities are used in conjunction with multicast update communications facilities in weakly-consistent, replicated data storage systems. Epidemic-style communications handle a wide variety of failures at multiple levels of the system using a single, very robust, but also relatively high-latency mechanism. Multicast communication offers much quicker propagation but less fault tolerance using a different mechanism. The epidemic-style communications and multicast communications, combined for use in weakly consistent replicated database systems obtain a design that offers the benefits of both individual approaches.

Abstract: A method and device for describing a complex color raster image as a collection of objects in a hierarchical and device independent format. The purpose of structured imaging (SI) is to expand the scope of a raster image to a collection of individually manipulable component objects. An SI is a hierarchical description of a single output image raster which may be used as one component of a page in a structured document. Objects contributing to the output raster may originate from text, graphics, other rasters or a combination thereof, and all maintain their heritage for selectability and modification. The SI describes not only the source data but also the image processing operations required for rendering the output raster. SI technology supports re-editability, customization and enhancement, automatic image assembly and high performance imaging. Thus, such a model has implications not only in an image editing and processing arena, but also in the filing and printing services used for image handling.

Abstract: A rotation member driving device and an image forming apparatus using the same are provided. Without enlarging the device and increasing the cost, by reducing a speed variation generated during one rotation of a rotation member such as an image holding member or an intermediate transfer member, the distortion or color misregistration of an image formed on or transferred onto the rotation member is reduced and a high quality image can be formed. In the rotation member driving device for rotating and driving the rotation member for image formation by a gear attached thereto, a relation between a phase of eccentricity of the rotation member and a phase of a cumulative pitch error in a rotation direction of the gear is set so that a variation of a surface speed due to the eccentricity of the rotation member is restrained from appearing on the image.

Also, the above-described colored very fine pixel (Si) is formed by both a first growth core which is formed by increasing the number of colored very fine pixels of a single cluster, and a second growth core which is formed by increasing the number of colored very fine pixels of another single cluster.

Abstract: A process in which participants in different situations define in plural epistemological spaces can be easily accommodated. An epistemological space synthesizing part synthesizes different epistemological spaces to generate a new epistemological space, thereby juxtaposing therein business processes defined in each of the epistemological spaces. An accommodated activity extraction part extracts a combinable activity from the activities of the combined business process. A common resource extraction part extracts a combinable resource (common resource) used or produced by the extracted activity. A pre- and post-activity extraction part extracts pre- and post-activities to be accommodated. A combined business process generation part generates a business process which automatically synthesizes combinable parts from the juxtaposed business processes. An accommodating activity extraction selection part uses information acquired by the accommodation information extraction part to present an accommodating method.

Abstract: A text categorizer classifies a text object into one or more classes. The text categorizer includes a pre-processing module, a knowledge base, and an approximate reasoning module. The pre-processing module performs feature extraction, feature reduction, and fuzzy set generation to represent an unlabelled text object in terms of one or more fuzzy sets. The approximate reasoning module uses a measured degree of match between the one or more fuzzy set and categories represented by fuzzy rules in the knowledge base to assign labels of those categories that satisfy a selected decision making rule.
