Patent number: 8047447Abstract: What is disclosed is a system and method for encoding and decoding data in a color barcode pattern using dot orientation and color separability. The spectral (wavelength) characteristics of the CMY colorants, commonly used in digital printing, and those of RGB sensors are exploited to achieve high capacity data embedding rates in color barcodes. The present method embeds independent data in two different printer colorant channels using dot orientation modulation. In the print end, dots of two colorants occupy the same spatial region. At the detector end, by using the complementary sensor channels to estimate the colorant channels, data is recovered in each colorant channel. The method approximately doubles the capacity of encoding methods based upon a single colorant channel and enables embedding rates which match or exceed that of other hardcopy barcodes known in the arts. The method is robust against inter-separation misregistration with a small symbol error rate.Type: GrantFiled: May 6, 2009Date of Patent: November 1, 2011Assignee: Xerox CorporationInventors: Orhan Bulan, Vishal Monga, Gaurav Sharma

Publication number: 20110260283Abstract: An electronic device, such as a thin-film transistor, includes a substrate and a dielectric layer formed from a dielectric composition. The dielectric composition includes a dielectric material, a crosslinking agent, and an infrared absorbing agent. In particular embodiments, the dielectric material comprises a lower-k dielectric material and a higher-k dielectric polymer. When deposited, the lower-k dielectric material and the higher-k dielectric material form separate phases. The infrared absorbing agent allows the dielectric composition to attain a temperature that is significantly greater than the temperature attained by the substrate during curing. This difference in temperature allows the dielectric layer to be cured at relatively high temperatures and/or shorter time periods, permitting the selection of lower-cost substrate materials that would otherwise be deformed by the curing of the dielectric layer.Type: ApplicationFiled: April 27, 2010Publication date: October 27, 2011Applicant: XEROX CORPORATIONInventors: Yiliang Wu, Ping Liu, Anthony James Wigglesworth, Nan-Xing Hu

Publication number: 20110264920Abstract: Systems and methods provide for a symmetric homomorphic encryption based protocol supporting communication, storage, retrieval, and computation on encrypted data stored off-site. The system may include a private, trusted network which uses aggregators to encrypt raw data that is sent to a third party for storage and processing, including computations that can be performed on the encrypted data. A client on a private or public network may request computations on the encrypted data, and the results may then be sent to the client for decryption or further computations. The third party aids in computation of statistical information and logical queries on the encrypted data, but is not able to decrypt the data on its own. The protocol provides a means for a third party to aid in computations on sensitive data without learning anything about those data values.Type: ApplicationFiled: April 27, 2010Publication date: October 27, 2011Applicant: FUJI XEROX CO., LTD.Inventors: Eleanor RIEFFEL, Jacob Biehl, Maribeth Back

Publication number: 20110262659Abstract: Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a first surface of a porous substrate with radiation emitted by at least one flash lamp. The radiation flash heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the first surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate from the first surface.Type: ApplicationFiled: April 21, 2010Publication date: October 27, 2011Applicant: XEROX CORPORATIONInventors: Gerald A.
