Patent number: 8083228Abstract: According to aspects illustrated herein, a method, a system, and a printmaking device for performing closed loop lateral and skew control of a sheet is provided. The printmaking device includes a feed path, printing module, and sheet registration system. First, the feed path moves the sheet in a process direction past the lateral sensor. Next, the sheet is registered by measuring a lateral position of one side edge of the sheet at a fixed reference using the lateral sensor and determining a lateral position error of the sheet using the lateral position measurement. After that, a sheet angular velocity is calculated based on the lateral position error using the registration controller. Then, the lateral position error is corrected using the at least one pair of registration nips to adjust the sheet by applying the sheet angular velocity to the sheet.Type: GrantFiled: December 28, 2009Date of Patent: December 27, 2011Assignee: Xerox CorporationInventors: Joannes N.

Patent number: 8086059Abstract: Sub-raster registration errors are compensated for through non-redundant overwriting. Data from adjacent rasters is written to a particular output raster so that the adjacent rasters share an influence at a point actually written to by a rendering device, thereby compensating for a sub-raster component of a registration error associated with writing to the particular point. If two writing passes per raster are used and the writing passes have equal influence (e.g., are written with equal power), then writing data from a first raster during a first pass and writing data from a second raster adjacent to the first raster during a second pass compensates for a sub-raster registration error of half a raster spacing. If two writing passes are associated with different influence (e.g., are written with ? and ? power respectively) and/or if additional writing passes are used, then addition sub-raster positions can be compensated for or emulated.Type: GrantFiled: November 30, 2007Date of Patent: December 27, 2011Assignee: Xerox CorporationInventors: Jess R. Gentner, Robert P. Loce

Patent number: 8086745Abstract: System and method for graphical user authentication using compact collages of regions of images. Image corpus is constructed by selecting similar quality images and filtering to further homogenize image quality. Regions are detected within the images and scored according to similarity and neighborhood information. Regions with lower scores provide less information about other regions and are more secure secrets. During enrollment, user selects secret images; decoy images are chosen by the system accordingly. Regions from secret images are selected as secrets according to the scoring of regions and regions from decoy images are selected as decoys. A collage is formed with secrets and decoys. Compact rendering enhances security and is suitable for small displays of mobile devices. Several rounds of challenge, requiring identification of secrets, are presented to the user. User is authenticated if a certain number of correct identifications of secrets within a number of rounds are achieved.Type: GrantFiled: August 29, 2008Date of Patent: December 27, 2011Assignee: Fuji Xerox Co., LtdInventors: Bee Yian Liew, Trista Chen, Volker Roth
