20110127331 | PHASE LOCKED IR ENCODING FOR PEENED 2D BARCODES - A system reveals a 2D barcode in a document. A 2D barcode generator selects the placement and at least one colorant combination of an image and at least one colorant combination for a 2D barcode on a document, where the at least one colorant combination of the image and the 2D barcode form a metameric pair. A print system receives data from the 2D barcode generator and places the image and the 2D barcode on the document. A light source selected or tuned to a wavelength corresponding to the colorant combinations utilized by the print system reveals the 2D barcode placed thereon. A decoding element decodes and extracts data from the revealed 2D barcode. | 06-02-2011 |
20110260392 | HORIZONTAL SENSOR AND VARIABLE PATTERN FOR DETECTING VERTICAL STACKER POSITION - This invention provides an effective and inexpensive stacker tray assembly apparatus and method for determining an elevator stacker tray location in the assembly. A sensor is attached to the stacker tray so that it is in sensing proximity to a continuous variable slanted shape marker. The marker has measurables therein where the measurables decrease in measurement as they proceed from a bottom of the marker to an upper portion of the marker. The sensor is substantially shorter than a length of the movable elevator stacker tray travel. | 10-27-2011 |

The method may include detecting an amount of a continuously variable sloped shape marker, determining a position of the adjustable feeder tray side guide of a feeder tray based on the detected amount of the continuously variable sloped shape marker, and outputting the determined position of the adjustable feeder tray side guide of a feeder tray to a user interface of the image production device. | 07-19-2012 |
20120218608 | IR SPECIALTY IMAGING METHODS AND SYSTEMS - Disclosed are methods and systems of printing an image encoded with an IR watermark on a substrate. According to an exemplary method, an effective gamut is used to render the image, wherein the effective gamut is formed by the intersection of a first and second gamut associated with producing a constant IR response. | 08-30-2012 |
20120261592 | CLEAR OVERCOAT COMPOSITIONS AND METHODS FOR USING AND DETECTING THE SAME - Present embodiments generally relate to a novel clear or colorless overcoat composition that may be used for overcoating, for example, ink based images and xerographic images. The overcoat composition, which may be used as a base for a clear solid ink, comprises one or more ultraviolet (UV) absorbing additives. Also included in the present embodiments is a method for using and detecting the overcoat composition in connection with a substrate, for example, a substrate that includes printed images thereon. | 10-18-2012 |
20130083303 | Multi-Level Imaging Using Single-Pass Imaging System Having Spatial Light Modulator and Anamorphic Projection Optics - An imaging system utilizes an anamorphic optical system to concentrate a two-dimensional modulated light field in a process direction such that a one-dimensional scan line image extending in a cross-process direction is generated on an imaging surface. The modulated light field is generated by directing homogeneous light onto light modulating elements arranged in a two-dimensional array. The array is configured using a scan line image data group made up of pixel image data portions. An associated group of the light modulating elements aligned in the process direction is configured by each pixel image data portion. When a pixel value is “partially on” (i.e., between “fully on” and “fully off”), the light modulating elements of the associated group are configured such that modulating elements located in the center of each group are activated, and elements located on the upper and lower ends of each group are deactivated. | 04-04-2013 |
20130088600 | MULTI-RESOLUTION VIDEO ANALYSIS AND KEY FEATURE PRESERVING VIDEO REDUCTION STRATEGY FOR (REAL-TIME) VEHICLE TRACKING AND SPEED ENFORCEMENT SYSTEMS - Systems and methods are disclosed that include a video-based analysis system that detects, tracks and archives vehicles in video stream data at multiple resolutions. The system includes an image capturing device that captures video stream data having video at a first high resolution. A vehicle detection module detects at least one vehicle within the video. A vehicle analysis module is configured to analyze the video and to extract one or more key vehicle features from the video to enable identification of a vehicle of interest (VOI) according to a set of predetermined criteria. A subsampling module creates a reduced resolution video stream in a second subsampled resolution that is lower than the first high resolution while maintaining the one or more extracted key features within the reduced resolution video stream in the first high resolution, and archives the reduced resolution video stream into a video database. | 04-11-2013 |
20130208121 | TRAFFIC CAMERA DIAGNOSTICS VIA TEST TARGETS - A method, system, and computer-usable tangible storage device for traffic camera diagnostics via strategic use of moving test targets are disclosed. The disclosed embodiments can comprise four modules: Moving test target management module, Moving test target detection and identification module, Image/video feature extraction module, and Sensor characterization and diagnostics module. A first test vehicle can travel periodically through traffic camera(s) of interest. The traffic camera(s) would then identify these test vehicles via matching of license plate numbers and then identify test targets in video frames through pattern matching or barcode reading. The identified test targets are then analyzed to extract image and video features that can be used for sensor characterization, sensor health assessment, and sensor diagnostics. The disclosed embodiments provide for a non-traffic-stop (i.e., non-traffic-interruption) traffic camera diagnostics. | 08-15-2013 |
20130208304 | Reflex-Type Digital Offset Printing System With Serially Arranged Single-Pass, Single-Color Imaging Systems - A reflex-type digital offset printing system includes four single-pass, single-color digital imaging systems arranged along a print medium feed path, and an image server that utilizes a positional clock to implicitly synchronize the imaging systems with the movement of a print medium along the feed path such that single-color (e.g., black, cyan, magenta, or yellow) image portions can be successively superimposed to produce a full color image. Each single-color digital imaging system utilizes a digital micromirror device and an anamorphic imaging system to generate a high energy, one-dimensional modulated line image that selectively evaporates fountain solution from an imaging cylinder before ink material is applied. Each imaging system utilizes a sensor that sends a respective drum position signal to the image server, and the image server utilizes the drum position signals to synchronize the single-color printing operations with the position of the printing medium. | 08-15-2013 |
20140022603 | VARIABLE DATA IMAGE WATERMARKING USING INFRARED SEQUENCE STRUCTURES IN BLACK SEPARATION - An image watermarking method includes a color transform on RGB image data to derive CMYK image data that define a constant K image. Variable infrared (IR) mark data defining an IR mark are received and a sparse two-dimensional pattern of black pixels is defined that corresponds to the variable IR data, e.g., using Gold codes or pseudorandom binary sequences. A watermarked black separation K″ is defined by embedding the sparse two-dimensional pattern into the constant K black separation K′ while maintaining local average levels. A watermarked image includes the watermarked black separation K″ in combination with the CMY separations of the constant K image. A decoding process includes using an IR microscope fitted with IR LEDs and an IR pass filter to capture an IR image, which is subjected to exposure correction, thresholding, and dilation operations to extract the two-dimensional pattern for subsequent correlation processing. | 01-23-2014 |
