    Abstract: PROBLEM TO BE SOLVED: To provide a method and system by which a parametric model of a processing operation of a color marking device can quickly be generated. SOLUTION: A PH(piecewise homeomorphism) recalculation step 108 adjusts an apex set with respect to a tetrahedron used altogether by a least square calculation with respect to surrounded data points to generate a consecutive expression of a true transfer function (f), a new apex is calculated to reconfigure the tetrahedron to surround a different set of actual data, a sampling data ground at the apex positions of the tetrahedron newly configured in used to calculate a new f' hat function. Having only to use the apexes of the tetrahedron as sampling data can calculate the new function f' hat with minimum data thereby quickly generating a parametric model.

    Abstract: PROBLEM TO BE SOLVED: To eliminate a system down-time of a machine without any unnecessary costs resulting from too early replacement nor too late replacement by using an improved method for accurately judging and monitoring a fatigue characteristics in a complicated system. SOLUTION: The system comprises a stage of increasing a nominal counter by a nominal count by cycles of a document processing system and a stage of generating a weighted count by multiplying the nominal count by at least one weighting factor. Then, a stage of summing the nominal count and weighted count in one or more supplementary diagnostic counters is provided thereafter. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To perform the fault prediction and diagnosis of an electronic system operated in a network environment. SOLUTION: The operating state of an electronic system 200 such as a printer is transferred from a status information circuit 250 through a link 75 to a diagnostic server 100 as status information. A data collecting circuit 140 transgress the copy of the status information to a data base 170 and a predictive/diagnostic circuit 150. A repair scheduling circuit 165 determines correcting and repairing operation on the basis the status information. The diagnostics server can start the automatic repair sequence of the electronic system 200 by a control signal.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for assessing an end of the life for high frequency service items in a document processing system. SOLUTION: The method comprises the steps of: accepting a system cycle as a nominal count; applying at least one weighting factor to the nominal count to yield at least one weighted count; and monitoring the system for a recovery condition; providing a recovery count in the event of the recovery condition; and summing the one or more weighted counts and the recovery count into a supplemental diagnostic counter.

    Abstract: PROBLEM TO BE SOLVED: To control a process by a printing system without obstructing a printing operation. SOLUTION: A control system uses a printed output image 68 as a continuous data source for control processes. This invention samples a wide range of colors in the image in order to calibrate a processing station and ensure accurate production of color and/or other image quality parameters. An image quality detector 63 examines the color data of a printed image after the image is fused to a copy sheet and compares the appearance of the output image to a desired appearance. When an error exists, the processing station is adjusted and variations and inconsistencies in the printed image are corrected. Also, the detector of this invention moves to different locations as the image is outputted from the printing system and samples a range of image quality parameters in the image.
