Abstract: A method and apparatus for positioning paper in a feed path by providing continuous feedback of copy sheet registration parameters is disclosed. More specifically, the present invention is directed to a system which compares measured sheet registration information with an ideal value stored in a microprocessor. These measured registration parameters are averaged and pertinent information is fed back to the control system of the copy sheet registration device. The information that has been fed back is then used to adjust the orientation of subsequent copy sheets, thereby allowing for ideal placement of the copy sheet onto the photoreceptor for successful transfer of a developed image.

Abstract: A method for maintaining the uniqueness of user entered data in a system for processing machine readable forms. Use of such a method in a system for processing machine readable forms facilitates forms reuse by creating keyword objects for new instances of user entered data, thus avoiding the creation of duplicate data. When user entered data is encountered in a machine readable form, the user entered data is compared to keyword objects of previously encountered user entered data. If no match is found, a new keyword object is created for the user entered data. Otherwise, it is assumed that the user entered data is a copy of previously entered data.

Abstract: A circuit for rotating a digital image through any angle at the rate of one pixel per clock period. First, the circuit divides the image to be rotated into blocks which can be rotated without pause once each is started. Then a nearest neighbor calculating circuit is used to determine the value of each rotated pixel in the block. The circuit is divided and pipelined so that each part can produce its output in one clock cycle. The nearest neighbor calculation is done in two sections of the circuit, and other sections of the circuit set up initial conditions or provide for transitions from one rotated scan line, or block, to the next.

Abstract: This invention discloses a method of correcting the measurement of the amount of light reflected by a document that is being processed by a digital image acquisition apparatus. A typical image acquisition apparatus measures the amount of light reflected from the surface of the original document and sets a corresponding set of electrical signals to a printing or storage module. Image acquisition usually requires illuminating the original document with a reflecting cavity, which causes the measurement of the amount of light present on the surface of the document to become distorted. The method disclosed by the present invention corrects this phenomenon by calculating the amount of light that reaches the surface of the original document by being reflected from the illumination system and the surrounding cavity. This allows the measured reflectance to be corrected, and the true reflectance to be used for subsequent output or storage.

Abstract: A low cost, modular, top adjustable slitter/perforator accessory for a machine that feeds paper to an output station is disclosed. The slitter/perforator is positioned just prior to the output station and when actuated places desired combinations of slits and/or perforations in paper passing through it. The accessory allows infinite location adjustments of slits and/or perforations along the width of paper by an operator while the machine continues to transport the paper. The slitter/perforator is automatically shut off when paper is directed to the machine's finisher.

Abstract: A photodiode sensor for use as a pixel element of a sensor array includes the sensor area segmented into a plurality of discrete portions. Each discrete portion has a distinctive responsiveness to incident illumination, either with regard to capacitance or sensitivity. The portions are in common communication with a data line for generating a sum charged output representative of the illumination on the cumulative sensor portions. Since the dynamic range of the cumulative discrete portions is greater than any single one sensor portion, a wider dynamic range for sensor operability is achieved.

Abstract: A system and method digitally scans a document using a high reflectance mode and a low reflectance mode. Initially, a platen cover provides a low reflectance background around the document and the scanner scans the low reflectance background and document to determine an edge of the document or to retrieve other image characteristics of the document. Subsequently, the platen cover changes so as to provide a high reflectance background around the document. The scanner then scans the high reflectance background and the document and produces digital image data relating to an image on the document.

Abstract: A projective display system includes a light source, a display surface, and a two dimensional light modulator array in an optical path between the light source and the display surface. The two dimensional light modulator array has a plurality of light modulators arranged in rows to modulate light from the light source, with at least one row being susceptible to failure. To compensate for any failed rows, an optical element redirects modulated light from presenting a first row of virtual pixels on the display surface to substantially occupy a second row of virtual pixels on the display surface. In conjunction with various image processing techniques for deblurring, this permits partial or complete correction for faulty rows of light modulators.

Abstract: A workspace management section collects resources related to a job and manages them as a workspace separately from resource management of a primary resource management section. The workspace has resource administration information as job relevant information, area information on a display screen, a base image, etc. A program can define the area information together with areas on the screen. A workspace display section superposes icons corresponding to the resources on the base image for display. The icons can be moved by a resource placement section. When an icon is moved to a different area, a job support processing execution section executes a program defined corresponding to the area to which the icon is moved, whereby different meanings can be imparted to the same resource depending on the area in which the corresponding icon is placed.
