  • Patent number: 9594994
    Abstract: The invention relates to a security element applied onto printing substrates (bank notes, securities, product packagings, identity cards/labels or other similar documents) by printing, comprising a unique identifier as primary information visible to the naked eye and secondary information protecting against copying non-visible to the naked eye. The unique identifier is typically a point code. Said secondary information is represented by a structure with the largest dimension of 2 to 40 microns, and due to printing distortions arising when the security element is applied onto a printing substrate, said secondary information is non-reconstructable from the print of the security element and a statistically analyzable inherent feature is associated to it. The invention also relates to a printed matter with such an inventive security element and to a method to check authenticity of a printed matter with the inventive security element in visible light (380-750 nm).

  • Patent number: 9561387
    Abstract: An ambiguity-free optical tracking system (100) includes a position sensor unit (104), a control box (106), a computer (110) and software. The position sensor unit includes two cameras (121 and 122) that track a plurality of individual infra-red reflecting markers (160) affixed on a patient's skin. Coordinates of the cameras in a coordinate system of the cameras are determined as part of a system calibration process by intentionally creating ambiguous markers with two true markers. Using this information, an ambiguity elimination algorithm automatically identifies and eliminates ambiguous markers. A recursive backtracking algorithm builds a one-to-one correspondence between reference markers and markers optically observed during treatment. By utilizing a concept of null markers, the backtracking algorithm deals with missing, misplaced and occluded markers.

    Abstract: A representation of a codeword is decoded by applying a first decoder of the codeword to the representation of the codeword. If applying the first decoder fails to decode the representation of the codeword then a second decoder of the codeword is applied to the representation of the codeword. Preferably, applying the first decoder consumes less power and is faster than applying the second decoder. Data are ported by encoding the data as a codeword, exporting the codeword to a corrupting medium, importing a representation of the codeword, and applying a first decoder to the representation of the codeword. If applying the first decoder fails to decode the representation of the codeword then a second decoder of the codeword is applied to the representation of the codeword.

  • Publication number: 20090242622
    Abstract: An image processing apparatus prints a mark-sensing sheet containing a plurality of entry fields. The image processing apparatus reads the mark-sensing sheet, determines a marked entry field entered by a user among the plurality of entry fields of the mark-sensing sheet, and stores information indicating the determined result. When the image processing apparatus rereads the mark-sensing sheet, the image processing apparatus compares the marked entry field entered by the user and information stored in a memory, thereby detecting the marked entry field that the user additionally enters for revision before rereading.

  • Patent number: 7573616
    Abstract: Methods and apparatus are disclosed for locating an area of interest within a digital image of a form captured by an imaging scanner. Specific examples include methods and apparatus for optical mark reading with a digital imaging scanner. In many of the methods, an image of a response form is captured by a scanner, and target areas for possible responses are located within the image based upon an expected location being adjusted as necessary for certain error-inducing defects in the forms or scanning process. Also disclosed are steps to normalize the darkness values of pixels captured from an optically scanned form.

  • Patent number: 7464875
    Abstract: An image acquiring apparatus capable of processing an image quickly and a method of acquiring the image. The image acquiring apparatus includes an image acquiring unit and a processing unit. The image acquiring unit acquires a source image, converts the source image into a first image data and then outputs the first image data. The processing unit produces a second image data according to the first image data and produces an image parameter according to the second image data. The image parameter executes an image correcting procedure. The size of the second image data is less than the size of the first image data.

  • Patent number: 7407102
    Abstract: An XML processing system for use in a barcode printer apparatus includes a computer system operatively coupled to the barcode printer apparatus. The computer system further includes an XML processor configured to receive, parse, and process an XML input data stream and obtain schema identified in the XML data stream from a schema repository. The XML processor validates the XML data stream based upon the schema obtained. Also included is an XSLT processor configured to obtain a stylesheet identified in the XML data stream from a stylesheet repository. The XSLT processor transforms data in the XML input data stream into transformed XML data based upon the stylesheet obtained. Also, an XSLFO processor formats the transformed XML data into formatted XML data based upon XSLFO instructions contained in the stylesheet. A barcode rendering subsystem then receives the formatted XML data and generates a bit map representative of the bar code label.

  • Patent number: 6991164
    Abstract: A bar code (10) has primary information (46, 48, 50, 51) encoded in one direction (e.g., horizontally) and secondary information (13, 21, 36) encoded in another direction (e.g., vertically) in single (11) or multiple tracks (35) in selected ones of the vertical bars (11) of a bar code (10). Using a non-linear, variable amplitude scanner, all of the bars are scanned in the one direction to obtain all of the primary information and all of those vertical bars having secondary information are scanned in the other direction to obtain all of the secondary information. The one direction which is perpendicular to the vertical bars (11), is determined by first rotating the scan path axis (86, 87) until both start (46) and end (48) code bars are read thereby placing the scan path entirely within the total bar code, and, then, further rotating the scan path (88, 89) to determine the direction of the minimum crossing width (Lsc 80) of the total bar code (10).
