20080283451 | Device and Method for Checking Banknotes - The invention relates to an apparatus and a method for checking bank notes wherein measuring values of the bank note to be checked are obtained and a classification of the bank note is carried out by evaluation of the measuring values in a plurality of checking steps, whereby the classification distinguishes in particular at least the classification categories, counterfeit, suspect and genuine bank notes, or acceptable or redispensable, and a linkage of a plurality of measuring values is formed at least in one checking step for deciding whether the checked bank note corresponds to a given classification category and this linkage term is compared with a corresponding tolerance range during evaluation. | 11-20-2008 |
20090132195 | Device and Method for Testing Sensors - An apparatus and a method for testing of sensors for documents of value and a pertinent test medium. A test medium ( | 05-21-2009 |
20090245590 | METHOD FOR IDENTIFYING SOILING AND/OR COLOUR FADING IN THE REGION OF COLOUR TRANSITIONS ON DOCUMENTS OF VALUE, AND MEANS FOR CARRYING OUT THE METHOD - In a method for detecting color transitions caused by soiling and/or color wear in at least one portion of a document of value ( | 10-01-2009 |
20110127414 | METHOD FOR CALIBRATING A SENSOR SYSTEM - The invention relates to a method for the calibration of a sensor system. | 06-02-2011 |
20130088712 | APPARATUS FOR CHECKING THE AUTHENTICITY OF VALUE DOCUMENTS - Testing the authenticity of a valuable document, whereby at least one intensity distribution of electromagnetic radiation passing through the valuable document in the dark field is detected in a spatially resolved manner and a spatially resolved dark field characteristic is determined therefrom. The actual authenticity test is then performed by a procedure in which selected test partial regions of the valuable document are assigned respectively to one of a plurality of suspicion classes, an interconnection region is formed from substantially interconnected test partial regions that were assigned to at least one specific suspicion class, and the valuable document, depending on the form and/or position of the interconnection region, is assigned to one of at least two authenticity categories which is linked to the at least one specific suspicion class. | 04-11-2013 |
20130170747 | METHOD FOR CHECKING AN OPTICAL SECURITY FEATURE OF A VALUE DOCUMENT - A method for checking a prescribed optical security feature on a prescribed portion of a value document based on pixel data of pixels of an image of the portion which are associated with places on the portion and render optical properties of the value document at the places. A check is made of whether a first number of those pixels whose pixel data, according to a first prescribed criterion, lie within a first reference region prescribed for the security feature exceeds a first minimum hit value prescribed for the security feature, and whether a first scatter of the pixel data of the pixels exceeds a first minimum scatter value prescribed for the security feature. An authenticity signal is formed which represents an indication of authenticity only when the first number exceeds the first minimum hit value, and the scatter the first minimum scatter value. | 07-04-2013 |
20130272598 | METHOD AND DEVICE FOR EXAMINING THE OPTICAL STATE OF VALUE DOCUMENTS - A method for examining the optical condition of a value document on the basis of a digital image of at least a specified region of the value document, the image comprising pixels, comprises searching the pixels of the digital image are searched for sets of error pixels which are respectively given in that the error pixels fulfill a specified deviation criterion for an impermissible deviation of at least one specified pixel property, and the distance of each error pixel of the respective set from at least one other error pixel of the same set does not exceed a specified distance that is greater than the distance of directly neighboring pixels of the digital image, and a number of sets found during the search and/or a value for at least one property of at least one of the sets found during the search is ascertained. | 10-17-2013 |
20130301086 | METHOD FOR GENERATING A DIGITAL IMAGE OF AT LEAST ONE SECTION OF A VALUE DOCUMENT - A method for generating a digital image of at least a portion of a value document, comprises transporting the portion of the value document in a specified transport direction at a specified speed, capturing pixel regions, and generating capture pixel data allocated to integration intervals. The capture pixel data of at least one of the sequences of capture pixel data are corrected. This reduces the influences of the movement of the value document in the transport direction during the capture of capture pixel data. | 11-14-2013 |
20130317960 | METHOD FOR THE PROCESSING OF BANKNOTES - A method for the processing of bank notes wherein serial numbers of the bank notes to be processed are ascertained and compared with stored serial numbers in order to control the processing of the bank notes, having a specification of several classes which respectively characterize at least one property of bank notes, an association of at least one of the classes with one or several serial numbers in order to associate at least one property with the bank note provided with the respective serial number, a storage of the respective serial number as well as of the associated class or classes, and a control of the processing of the bank notes by means of the stored classes associated with the respective serial numbers. | 11-28-2013 |
20140233829 | Method for Checking the Production Quality of an Optical Security Feature of a Value Document - A method for checking the production quality of a prescribed optical security feature in or on a prescribed portion of a value document on the basis of pixel data of pixels of an image of the prescribed portion which are respectively associated with places in or on the portion and render optical properties of the value document at the places whether a first number or share of those pixels, whose pixel data, according to a first prescribed criterion, lie within a first reference region prescribed for the security feature exceeds a first minimum hit value, and whether a first scatter of the pixel data of those pixels lying within the first reference region for the pixel data according to the first criterion exceeds a first minimum scatter prescribed for the security feature. A quality signal from the check represents an indication of a sufficient printing quality according to certain criteria. | 08-21-2014 |
