20090094198 | METHOD AND SYSTEM FOR IDENTIFICATION OF REPEAT PRINT JOBS USING OBJECT LEVEL HASH TABLES - A method and system for identifying print jobs that are repeats of a previously completed job utilizing an object level hash table. Received print jobs can be parsed into meaningful classes of objects and a table of hash values can be computed for objects in each class and for each print job. A synopsis comprising the table of hash values can be retained in a database along with the job specific settings. A newly encountered job can be then declared as a repeat of a previous job based on the hashes for the new job that match the hash values for the previous job stored in the database. The classes of objects are readily determinable in common document formats used for print job submission, such as PDF. | 04-09-2009 |
20100060942 | ENCODING MESSAGE DATA IN A COVER CONTONE IMAGE VIA HALFTONE DOT ORIENTATION - What is disclosed is a novel system and method for encoding/decoding data in a cover contone image via halftone dot orientation modulation. Arrays of halftone threshold values are used to determine a desired orientation, e.g. 0/90°±45° for a given single data value of the original message to be embedded. Message data is embedded as a function of halftone dot orientation. Detection modeling of the print-scan process enables the determination of dot orientation from the image scan via statistically motivated image moments. A probabilistic model of the print-scan channel conditions received moments on input orientation. Density values of the received moments are used to determine dot orientation for each halftone cell. The embedded data is retrieved based on the determined orientations. The present method is applicable to areas of data embedding, document security, and the like. | 03-11-2010 |

20100085605 | LOSSLESS COMPRESSION OF COLOR LOOK-UP TABLE VIA HIERARCHICAL DIFFERENTIAL ENCODING OR CELLULAR INTERPOLATIVE PREDICTION - A color look-up table (CLUT) is compressed in a lossless manner. The CLUT includes nodes that convert values of a first color space to corresponding values of a second color space. The CLUT is received in a serialized node-by-node manner. For each of some of the nodes the following is performed in the order in which the nodes are received in the serialized node-by-node manner. First, a difference value is determined that represents compression of a value of the node, in accordance with a hierarchical differential encoding approach or in accordance with a cellular interpolative prediction approach. Second, the difference value is stored in lieu of the value of the node being stored, to compress the value of the node in the lossless manner. | 04-08-2010 |
20100282851 | METHOD FOR ENCODING AND DECODING DATA IN A COLOR BARCODE PATTERN - 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. | 11-11-2010 |

20120150381 | In-Car Service Interval Adjustment Device - Disclosed is a device and method for providing service interval notifications to a vehicle operator, and to incorporate relevant vehicle operating conditions which most directly impact the longevity of engine lubrication and other wear prone components of vehicles. Wear prone conditions which are determined include city driving, frequency of “cold” starts, frequency of “winter” “cold” starts, and high load high grade travel. The device and method utilize as a primary input a location aware sensor device and as a secondary input a source for the ambient temperature either retrieved from an Internet source or a local ambient temperature sensor. No direct vehicle sensor is utilized for the service interval adjustment performed by the device and method. | 06-14-2012 |
20120197484 | System and Method for Tracking Vehicle Mileage with Mobile Devices - Disclosed is a system for tracking vehicle locations and accumulating mileage for said vehicles by detecting intervals when said vehicles are in proximity to mobile devices and utilizing the location aware sensors of said mobile devices to determine vehicle locations. Proximity between mobile devices and vehicles is determined by short range data communication identification. Multiple vehicles and drivers may thus be tracked for trip, interval, or overall mileage traveled. | 08-02-2012 |

20140282949 | System and Method for Account Access - The longstanding problems of user password management and security, and user authentication are addressed. Disclosed is a system and method for providing a means for a user to identify themselves with configurable levels of authentication in order to receive limited access or services while protecting user privacy. As a user inputs information related to their identity into an interface, the system searches an indexed database which may include both registered users and/or unregistered customers indexed from disparate data sources. The system presents the user matching results from the search in an obscured form from which the user selects and authenticates his or her identity. Unregistered users identified during the process may be automatically registered in certain embodiments, or no account may be needed in other embodiments | 09-18-2014 |
