Abstract: The present invention relates to a method for producing an optical recording medium. In the method, on the surface of a recording layer formed by spin-coating a first coating solution containing a photo-isomerizable component, a second coating solution that contains a photo-isomerizable component that can be isomerized by radiation having the same wavelength as radiation used for isomerizing the photo-isomerizable component contained in the recording layer and incapable of dissolving the recording layer is spin-coated to form an intermediate layer. Since the intermediate layer thus formed cannot be dissolved by the first coating solution, a recording layer is further laminated on this layer. Thus, it becomes possible to make the recording layer thicker and also to provide a high-density recording characteristic.

Abstract: A method for processing segmentation tags to generate a block level tag representative of a group of segmentation tags includes identifying a block of the segmentation tags; compiling a block statistic from a plurality of segmentation tags within the block; determining a most predominant segmentation tag and a second most predominant segmentation tag in the plurality of segmentation tags; and generating a block level tag for the block based on the most predominant segmentation tag, the second most predominant segmentation tag and the block statistic.
Abstract: Conversion between different codes can be implemented at high speed by a small device. A code input unit inputs a code. A compatible information reference unit refers to compatible information of each compressed symbol before and after code conversion, which then sends out compatible information data to a compressed symbol conversion unit. The compressed symbol conversion unit converts each of the compressed symbols in the input code data to a form adapted to a code to be converted based on the compatible information data, which then sends out converted code data to a converted code output unit.
Abstract: A process involving heating a mixture of a colorant dispersion, a latex emulsion, and an optional wax dispersion in the presence of a coagulant containing a metal ion, a base, and an organic sequestering agent, and wherein said heating involves a first heating and a second heating, and wherein the second heating is at a higher temperature than the first heating; and wherein said higher temperature is equal to about or above about the Tg of polymer or resin contained in said latex emulsion.
Abstract: In a device of the present invention for allowing signal light to enter a light guide body using an optical fiber, a light guide body, which is constituted by dispersing particles for scattering the signal light in an optical medium, is selected as a light guide path which requires an area where a light diffusing function is performed just after incidence of the signal light. An optical connecting material intervenes between one end of the optical fiber from which the signal light is output and opposed one end surface of a particle dispersing light guide body and a desired diffusing function is obtained.

Abstract: Systems and methods of registration system control are provided that compensate for differences in physical properties of various substrates being transported through the system that impact the displacement of the substrate through a given path. Exemplary systems of the invention include at least one roll pair formed by a first, driven roll and a second roll defining a nip therebetween that is part of the transport path through which a substrate is passed. A prestored lookup table includes empirically- or theoretically-derived compensation factors for plural different kinds of substrates, with each compensation factor being based on physical characteristics of the substrate that impact actual travel length of the substrate along the transport path, such as the substrate's mass per unit area, which has been found to have a strong correlation with a substrate's bending stiffness, which has been found to have a strong correlation with detected deviations in linear travel path.
Abstract: Methods and systems for document image decoding incorporating a Stack algorithm improve document image decoding. The application of the Stack algorithm is iterated to improve decoding. A provisional weight is determined for a partial path to reduce template matching. In addition, semantically equivalent hypotheses are identified to reduce redundant hypotheses.

Abstract: A printer includes a transport path, a processing unit, a plurality of transport abnormality detection, a transport page state judgment unit, and a recovery printing control unit. A paper is continuously transported along the transport path. The transport path is divided into a plurality of transport sections in the middle of the processing unit. The transport abnormality detection units detect transport abnormality of the paper in the transport sections, respectively. The transport page state judgment unit judges state of the paper in each of transport sections. When one of the transport abnormality detection units detects the transport abnormality of the paper in one of the transport sections, the recovery printing control unit sets content of a transported page of the paper present in the one of the transport sections and content of a page following to the transported page as contents to be printed thereafter, and resumes printing.
Abstract: A method for rendering a raster output level determines an image position of a pixel of interest (POI) within an image. An intended raster output level, which corresponds to the POI, is received into a processing device. A final raster input level is determined as a function of the image position and the intended raster output level. The final input level and the image position are transmitted to an output device. An actual raster output level is rendered, via the output device, at a position on an output medium corresponding to the image position. The actual raster output level substantially matches the intended raster output level.

Abstract: A system for graphically displaying data, and for allowing users to interactively analyze said data, particularly with respect to detecting and analyzing any relationships within said data. The invention is particularly suited to analysis of large multi-variate matrix data or two-dimensional data sets that can be stored in a data array. The system includes a visual Data Pane, that is used by an operator to provide a focus+context view into the data. Each data item is initially presented as a small object or region on the operator's screen. In response to an operator signal, the source data value and data type of a source data item in the array is obtained and indirectly represented in the Data Pane image. During a focusing operation the area of interest within the constraints of the Data Pane window is expanded, and related or more detailed data is presented to the user.
Abstract: Electrostatic latent images of a pattern image and an original image are formed on each of a plurality of image carriers. Each image carrier is provided with a developing unit and a transfer unit, and images of a reference color and colors other than the reference color are formed on a continuous sheet of paper. Detectors that detect the pattern images on the continuous sheet are disposed at conveying direction downstream sides of image carriers, and positional offset amounts of the pattern images of the colors other than the reference color are computed. On the basis of a detection of the pattern image of the reference color, a start position of electrostatic latent image formation at each image carrier is determined. Further, the start position is corrected on the basis of a positional offset amount computed at a time of transferring a preceding pattern image.
Abstract: Embodiments of the present invention include a video server that can detect and track the image of a pointing indicator in an input video stream representation of a computer display. The video server checks ordered frames of the video signal and determines movements for a pointing indicator such as a mouse arrow. Certain motions by the pointing indicator, such as lingering over a button or menu item or circling a button or menu item can provoke a control action on the server.
