Publication number: 20030049042Abstract: A corrugating air knife for stripping a sheet from a fusing member. The air knife includes a manifold connected to an air supply source and has an outlet which directs a flow of air across a sheet path adjacent the fuser. The air knife further includes ribs through which air flows to create localized air flows which when directed at the sheet cause it to corrugate as it separates from the fuser. The corrugation increases the beam strength and prevents wrap jams.Type: ApplicationFiled: January 14, 2002Publication date: March 13, 2003Applicant: Xerox CorporationInventor: Gregory V. Bogoshian

Patent number: 6532081Abstract: For blending two color transformation look-up tables, the weights used for combining the tables are designed such that transitions from one look-up table to another are smooth and do not create objectionable artifacts. Building the individual weights includes obtaining the position of a given input point from the input color space, both in the input device and an output device gamut. Weight calculation is obtained by (1) if the input color falls in the intersection of predefined percentages of both the input gamut and the output gamut, then a pictorial LUT is used and the weight is set to 1.0; (2) if the input color falls outside the input and/or output gamut, then a graphics LUT is used and the weight is set to 1.Type: GrantFiled: July 23, 1999Date of Patent: March 11, 2003Assignee: Xerox CorporationInventors: Ann M. Cecchi, Katherine Loj, Clara Cuciurean-Zapan

Patent number: 6532086Abstract: In the known time delay and integration (TDI) color scanner, a different color filter covers each group m of N rows. The spectral sensitivity of each group m of N rows can be improved if some of the photosites in one group are covered by filters from other groups. The TDI color scanner produces a first set of device dependent color signals which may be transformed into a corresponding set of color signals, which may approximate device independent color signals, using a transformation matrix. Typical TDI scanners include photosites arranged in rows divided into groups of rows, and a color filter is associated with each group. However, in the inventive TDI color scanner, each color filter covers more or less than the rows in its corresponding group and some or none of the rows in other groups. The color filters therefore produce a second set of color signals that are linear combinations of the first set of device dependent color signals and are based on a number of rows of each group covered by each filter.Type: GrantFiled: November 19, 1999Date of Patent: March 11, 2003Assignee: Xerox CorporationInventor: Joseph Paul Tallie

Patent number: 6532093Abstract: A micro-optical-electrical-mechanical laser scanner is configured from a silicon-on-insulator substrate having a silicon substrate layer, a buried oxide layer, and a single crystal silicon device layer. A first device layer portion having a micro-mirror fabricated therefrom. A laser is connected to a second device layer portion, and a hinge connects the first device layer portion and the second device layer portion. The hinge is formed with a bimorph material, wherein the bimorph material creates built-in stresses in the hinge. The bimorph hinge moves the released micro-mirror out of the horizontal plane to a position for either directly or indirectly reflecting laser light emitted from the laser.Type: GrantFiled: December 6, 2000Date of Patent: March 11, 2003Assignee: Xerox CorporationInventors: Decai Sun, Michel A.

Patent number: 6530655Abstract: A drip plate design is provided for a solid ink color printer which reliably directs on-demand ink flow and securely retains solidified ink. The drip plate design includes a combination of one or more sized and shaped cutouts and protrusions for anchoring a solidified ink stick when the printer is not in operation and protrusions that impede downward movement of independent portions of an ink stick so that they remain in contact with a heated melt plate long enough to substantially melt, thereby inhibiting the unchecked sliding off of large separated slivers and chunks of ink during melt and delivery.Type: GrantFiled: May 31, 2001Date of Patent: March 11, 2003Assignee: Xerox CorporationInventors: Brent R. Jones, Frederick T. Mattern, Paul T. Sullivan, Bjoern E. Brunner

Publication number: 20030046560Abstract: An encryption/decryption system capable of supplying data only to a user making a request. A computer encrypts data with a common key, encrypts the common key with a public key, and transmits the encrypted data and the encrypted common key. A copy machine receives these data, encrypts challenge data with the public key, and transmits the encrypted challenge data to an IC card. The IC card decrypts the encrypted challenge data with a private key, and feeds the decrypted challenge data back to the copy machine. The copy machine transmits the IC card an encrypted common key of reception data offering decrypted challenge data identical to the original challenge data. The IC card decrypts the encrypted common key and feeds the decrypted common key back to the complex copy machine. The complex copy machine decrypts the encrypted data with the common key.Type: ApplicationFiled: August 29, 2002Publication date: March 6, 2003Applicant: FUJI XEROX CO., LTD.Inventors: Kohshiro Inomata, Yasutoshi Maeda

Publication number: 20030044193Abstract: In a digital printing apparatus, such as a xerographic or ink-jet printer, test marks, such as halftone patches or fiducial marks for image registration, are generated on demand. Coordinates of a desired location of the test mark within an imageable area (such as on a print sheet or on a photoreceptor), as well as a selection of the desired type of test mark, are entered through a user interface. Also entered is data about conditions under which image-quality tests using the test marks are to be performed. Information about the test mark and test conditions is retained as a small number of scalar values. The system enables test methods for a machine to be changed easily, and a basic set of system software can be readily applied to different types of printing hardware.Type: ApplicationFiled: August 28, 2001Publication date: March 6, 2003Applicant: Xerox CorporationInventors: Michael J.

Publication number: 20030046055Abstract: A method factors a functional (i.e., ambiguous) finite state transducer (FST) into a bimachine with a reduced intermediate alphabet. Initially, the method determines an emission matrix corresponding to a factorization of the functional FST. Subsequently, the emission matrix is split into a plurality of emission sub-matrices equal in number to the number of input symbols to reduce the intermediate alphabet. Equal rows of each emission sub-matrix are assigned an identical index value in its corresponding factorization matrix before creating the bimachine.Type: ApplicationFiled: December 18, 2000Publication date: March 6, 2003Applicant: Xerox CorporationInventor: Andre Kempe

Publication number: 20030043416Abstract: In a network-based input scanning system, wherein a sender scanning a hard-copy document at a scanner sends the resulting image data to an electronic mail address, the scanner appends an electronic mail address of the sender in the “From:” space of the electronic mail message. In this way, status messages or other responses to the electronic mail message bearing the image data are directed to the sender's computer, and not only to the scanner itself. The identity of the sender is determined by a network-login step the sender uses to access the scanner.Type: ApplicationFiled: April 2, 2002Publication date: March 6, 2003Applicant: Xerox CorporationInventors: Darrell L.
