Publication number: 20110078191Abstract: A method and an apparatus for training a handwritten document categorizer are disclosed. For each category in a set into which handwritten documents are to be categorized, discriminative words are identified from the OCR output of a training set of typed documents labeled by category. A group of keywords is established including some of the discriminative words identified for each category. Samples of each of the keywords in the group are synthesized using a plurality of different type fonts. A keyword model is then generated for each keyword, parameters of the model being estimated, at least initially, based on features extracted from the synthesized samples. Keyword statistics for each of a set of scanned handwritten documents labeled by category are generated by applying the generated keyword models to word images extracted from the scanned handwritten documents. The categorizer is trained with the keyword statistics and respective handwritten document labels.Type: ApplicationFiled: September 28, 2009Publication date: March 31, 2011Applicant: Xerox CorporationInventors: Francois RAGNET, Florent C.

Patent number: 7917049Abstract: A control method for monitoring the cleaning performance of a single or multiple blade xerographic cleaning subsystem includes looking at the photoreceptor post-cleaner with a full width array sensor and adjusting the blade load on the photoreceptor to the minimum required to maintain effective cleaning. Blade load is adjusted using a stepper motor. Monitoring of cleaning failures can be done during non-print time, when a toner patch is developed to evaluate cleaning. Re-adjustment is needed periodically since environmental stresses can change, and the blade ages due to set and wear. Two toner patches at the ends of the blade with two stepper motors can be used to assure the same load from end to end.Type: GrantFiled: June 10, 2008Date of Patent: March 29, 2011Assignee: Xerox CorporationInventors: Bruce E Thayer, Richard W Seyfried

Patent number: 7914000Abstract: A method and system for performing sheet registration are disclosed. Output values for a sheet may be identified within a reference frame. A difference between each output value and a corresponding desired output value may be determined. Input values may be determined based on at least the differences. State feedback values may be determined based on information received from one or more sensors. Jerk values may be determined for multiple drive rolls based on the input values and the state feedback values. A desired angular velocity for each drive roll may be determined based on the corresponding jerk value. A motor voltage may be determined for each drive roll that tracks an observed angular velocity value to the desired angular velocity value. The jerk values may create a linear differential relationship between the input values and the output values. The steps may be performed multiple times.Type: GrantFiled: June 6, 2007Date of Patent: March 29, 2011Assignee: Xerox CorporationInventor: Jack Gaynor Elliot
