Patent number: 8805033Abstract: This document relates to systems and method for latent fingerprint detection using specular reflection (glare). An exemplary system may include a light source alignment portion configured to align a light source at an illumination angle relative to a sample surface such that the light source illuminates a sample surface so that the surface produces specular reflection. The system may also include a specular reflection discriminator that directs the produced specular reflection to an optical detector aligned relative to said sample surface at an alignment angle that is substantially equal to an angle of reflection of the produced specular reflection. Preferably, the directed specular reflection does not saturate the optical detector; and the optical detector captures the specular reflection from the sample surface and generates image data using essentially only the specular reflection.Type: GrantFiled: November 2, 2011Date of Patent: August 12, 2014Assignee: Lockheed Martin CorporationInventors: Edward Miesak, V.

Method for separating worn bank notes from a quantity of bank notes in bank note processing machines
Patent number: 8797516Abstract: A method is proposed for separating worn bank notes from a quantity of bank notes in bank note processing machines. A target rate cunfit,0 of bank notes to be separated is prescribed. The bank notes are assessed one after the other. In the process they are counted. Further, the value of at least one physical parameter of each bank note affected by wear is measured during the assessment. The measured value, or a value derived therefrom, of each bank note is compared with a threshold value during the assessment. If the threshold value is exceeded, the bank note in question is separated during the assessment. The separated bank notes are counted during the assessment. The threshold value is adapted after assessing each bank note or after a fixed prescribed number m>>n of bank notes by feedback control. The control parameter is the rate cunfit,i of the bank notes separated up to said bank note, and the set parameter is the threshold value.Type: GrantFiled: May 28, 2010Date of Patent: August 5, 2014Assignee: Beb Industrie-Elektronik AGInventor: Armin Stockli -

Publication number: 20140204366Abstract: A sensor for checking value documents is arranged to carry out a self-test for testing its functionality. The sensor in the self-test reacts to at least one malfunction that is ascertained during the self-test and hinders the check of the value documents by the sensor automatically employing for checking the value documents, instead of the operating mode provided for checking the value documents.

Patent number: 8780206Abstract: The present invention provides a method and system for imaging documents such as bank notes. The method comprises passing a document past an image sensor such as a line scan camera while sequentially illuminating the document using multi-mode illumination. Two or more light sources are used, each one producing a different mode of illumination. A lookup table divides documents into discrete successive sections (i.e. scan lines) and specifies a mode of illumination (e.g., color, azimuth, reflective, transmissive) for each section of a document during imaging. As the document passes the image sensor, the light sources are activated according to the sequence specified in the lookup table, producing an interleaved, multi-mode image of the document.Type: GrantFiled: November 25, 2008Date of Patent: July 15, 2014Assignee: De La Rue North America Inc.Inventor: Ronald Bruce Blair

Publication number: 20140125968Abstract: The invention relates to a method for checking value documents by which the similarity of the intensity spectrum of a value document to be checked to a reference spectrum can be tested. To check the similarity of the intensity spectrum recorded from the value document to be checked to the reference spectrum, not the recorded intensity spectrum itself is compared with the reference spectrum, but rather a corrected intensity spectrum adapted to the reference spectrum, which arises from the recorded intensity spectrum by a linear correction. The correction parameters of the linear correction function are ascertained by adapting the linearly corrected intensity spectrum to the reference spectrum. Through the adapting it is achieved that fluctuations of the recorded intensity spectrum that are due to measuring technology are compensated at least partly.Type: ApplicationFiled: April 4, 2012Publication date: May 8, 2014Applicant: GIESECKE & DEVRIENT GMBHInventors: Wolfgang Rauscher, Jorg Frankenberger

Patent number: 8531652Abstract: A counterfeit detection apparatus is formed as a desktop currency detector which has a slim configuration and a small footprint on the order of about 175 mm×100 mm. The desktop counterfeit detector provides white light that can shine from below a currency bill that is placed on its translucent cover and also provides and overhead UV lamp which is situated approximately 30 mm above the translucent light table. The detector also provides a compartment for a counterfeit detector pen which contains a special ink formulation that can apply a color changing test mark to a currency bill to test its reaction with the paper to determine its genuineness. Thus, the detector provides a three-test opportunity to check the genuineness of a currency bill by white light, UV light and a specially formulated ink suitable for checking the paper stock.Type: GrantFiled: April 8, 2011Date of Patent: September 10, 2013Assignee: Dri-Mark ProductsInventors: Dwight Haas, Mark Dobbs, Jeffrey Kelsoe

Patent number: 8514379Abstract: A document processing system includes an input receptacle for receiving documents. A transport mechanism receives the documents from the input receptacle and transports the documents past an image scanner and a discrimination unit. An output receptacle receives the documents from the transport mechanism after being transported past the full image scanner and the discrimination unit. The image scanner operates to obtain images of the documents and further operates to obtain images of selected portions of the documents, and further can obtain information contained in the selected portions. The discrimination unit operates to determine document authenticity. A system controller directs the flow of documents over the transport mechanism.Type: GrantFiled: December 11, 2009Date of Patent: August 20, 2013Assignee: Cummins-Allison Corp.Inventors: John E. Jones, Paul A. Jones, William J. Jones, Douglas U. Mennie
