20110196650 | DUAL CROSS BEAM SENSOR SYSTEM AND METHOD FOR MEASURING LEAD EDGE AND/OR TRAIL EDGE MEDIA CURL - A system and method for measuring a lead edge and/or a trail edge media curl utilizing a dual cross beam sensor. The dual cross beam sensor includes one or more pairs of emitters (e.g., a pair to two pairs of emitters) and one or more detectors positioned sequentially in a media path so that a media passes via dual cross beams. Timing data with respect to the media can be measured as the media crosses via the dual cross beam sensor from a leading edge and/or trailing edge. A true instantaneous media speed and a curl height (i.e., media tip height or media curvature) can be simultaneously calculated from the timing data associated with the lead edge/trail edge with respect to each single cross beams of the dual cross beam sensor. An average curl height can be then calculated to enhance the accuracy of the media curl measurement. | 08-11-2011 |
20110228282 | METHOD AND SYSTEM FOR CALIBRATING A MULTIPLE-BEAM CURVATURE/FLATNESS SENSOR - A method and system for calibrating a multiple-beam curvature/flatness sensor in order to provide an accurate media curvature/flatness measurement. One or more flat media sheets are passed through a multiple-beam media curvature/flatness sensor and the timing data associated with the lead edge/trail edge crossing each beam associated with the multiple beam curvature/flatness sensor is used for the calibration of the curvature/flatness sensor system. The unknown variables in the media curvature/flatness equation which takes into consideration of the manufacture and assembly errors of the sensor as well as the media deflection due to gravity can be determined and eliminated in order to obtain a calibrated media curvature/flatness equation. The calibrated media curvature/flatness equation can further be applied in the curvature/flatness measurement in order to achieve accurate measurement results. | 09-22-2011 |
20110234724 | CORRUGATED PRE-CURLER FOR MEDIA HOLD-DOWN TRANSPORT - A system for maintaining depth of focus in an ink jet printer between a series of print heads and corrugated media includes a vacuum transport in combination with a heating element positioned upstream of the series of print heads in order to help the vacuum transport acquire the corrugated media and seal edges of the corrugated media against a platen. | 09-29-2011 |
20110315031 | WEB PRINTING SYSTEMS HAVING SYSTEM RESONANCE TUNER - A method and apparatus herein supply one or more media characteristics of a continuous media material (such as printing media) being supplied to rollers of an apparatus (such as a printing apparatus). The method and apparatus adjust the position of at least one of the rollers/shafts, relative to other rollers/shafts, based on the media characteristics to cause the media material to exhibit a target resonance frequency when being processed through the rollers. The method and apparatus can also identify excitation frequencies of vibrations produced by the apparatus as the apparatus feeds the continuous media material along the rollers and set the target resonance frequency at a value that is different from the excitation frequencies to prevent the apparatus from exciting the continuous media material at or near a resonant frequency of the processing system transporting the continuous media material. | 12-29-2011 |
20120059617 | Iterative Learning Control for Motion Error Reduction - An apparatus for reducing registration errors in a media handling device. The apparatus including an image-bearing member having sheets individually pass across the image-bearing member. Each sheet pass corresponds to one of a series of iterations between the image-bearing member and the sheets. The image-bearing member is operatively coupled to a controller for regulation motion of the image-bearing member. The controller receives input signals representing at least one measured disturbance. Each disturbance being defined by a pattern of image-bearing member movement away from and substantially returning to a reference state of motion. A repetition of the pattern being coincident with at least one of the iterations, wherein based on the measured disturbance, the reference state and an indication associated with when the pattern will repeat, a modified signal is generated for the actuator to adjust the image-bearing member motion in coordination with the indication. | 03-08-2012 |
20120301186 | WEB FEED SYSTEM HAVING COMPENSATION ROLL - An apparatus includes a photoreceptor belt, a fixed transfer roller positioned on the inside of the photoreceptor belt, and a movable transfer roller positioned on the outside of the photoreceptor belt. The fixed transfer roller and the movable transfer roller are positioned to form a nip, and the photoreceptor belt and a web of print media are positioned in the nip. Also, a support roller and a compensation roller contact the web of print media. The support roller is positioned between the compensation roller and the nip. A physical link is connected to the support roller and the compensation roller. The physical link moves the support roller and the compensation roller so as to keep a constant tension on the web of print media. | 11-29-2012 |

20140122032 | METHODS, SYSTEMS AND PROCESSOR-READABLE MEDIA FOR OPTIMIZING INTELLIGENT TRANSPORTATION SYSTEM STRATEGIES UTILIZING SYSTEMATIC GENETIC ALGORITHMS - Methods, systems and processor-readable media for modeling and optimizing multiple ITS (Intelligent Transportation System) strategies utilizing a systematic genetic algorithm. A traffic simulation model can be configured in conjunction with a genetic algorithm based optimization engine for optimizing the transportation models. An origin-destination matrix that minimizes discrepancies between a simulated and an observed link traffic count can be estimated by considering a road network and a traffic count with respect to a region. A driver behavior can then be determined utilizing the origin-destination matrix via calibration so that the simulation model can replicate a freeway traffic flow in the region. An optimal parameter with respect to the ITS strategies can be determined to optimize a set goal with respect to a given constraint. Such an approach meets a level of service (LOS) metric as well as a revenue target under the applied ITS strategies. | 05-01-2014 |
