Patent number: 10109133Abstract: An apparatus, a corresponding method, and value-document processing system for checking value documents that has at least two radiation sources for giving off electromagnetic radiation with which a value document is irradiated, at least one sensor for capturing the electromagnetic radiation emanating from the value document, and generating corresponding sensor signals. The apparatus has an evaluation device configured to derive from the sensor signals corrected sensor signals taking into account at least one spectral property of the electromagnetic radiation of the at least two radiation sources. The sensor signals corrected in this way reproduce the actual reflection or transmission behavior of the value document substantially more precisely than the uncorrected sensor signals. Disturbing remission or transmission artifacts may be attributed to so-called auxiliary emissions of the radiation sources are eliminated or at least reduced.Type: GrantFiled: October 23, 2015Date of Patent: October 23, 2018Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Jörg Frankenberger, Thomas Giering, Wolfgang Rauscher

Patent number: 9418499Abstract: 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: GrantFiled: April 4, 2012Date of Patent: August 16, 2016Assignee: GIESECKE & DEVRIENT GMBHInventors: Wolfgang Rauscher, Jorg Frankenberger

Patent number: 9245400Abstract: 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. A modified operating mode employs at least one other measured value of the sensor for checking the value documents than is determined in the operating mode provided for checking the value documents. In contrast to the hitherto customary function failure of the sensor, the sensor can continue being operated for checking the value documents despite the malfunction.Type: GrantFiled: August 13, 2012Date of Patent: January 26, 2016Assignee: GIESECKE & DEVRIENT GMBHInventors: Jorg Frankenberger, Michael Bloss, Erich Kerst

Patent number: 9171412Abstract: A sensor for checking different features of value documents is arranged to carry out a self-test for testing its functionality. Before the sensor carries out its self-test, at least one of the features that is to be checked by the sensor is selected. It is provided in the self-test that the sensor rates a malfunction ascertained in the self-test differently and reacts to the ascertained malfunction differently in dependence on the selected feature. While a malfunction of the sensor has hitherto always led to a failure of the sensor, the sensor, despite ascertained malfunctions, can nevertheless carry out the check of certain features. It is achieved that the number of function failures of the sensor is reduced through the different reactions of the sensor to the ascertained malfunction in dependence on the feature.Type: GrantFiled: August 13, 2012Date of Patent: October 27, 2015Assignee: GIESECKE & DEVRIENT GMBHInventors: Jorg Frankenberger, Michael Bloss, Erich Kerst

Patent number: 8711339Abstract: A spectral sensor for inspecting value documents, includes an illumination device for illuminating the value document, imaging optics and a detection device. The illumination device contains a plurality of light sources with emission spectra that differ from one another, and which are switched on and off in succession, to illuminate a region of the value document with an illumination sequence consisting of light pulses with different emission spectra. One measured value is detected for each of the light pulses to record the spectral intensity distribution of the detected light. The plurality of light sources cover a section of the near infra-red spectral range and/or a section of the visible spectral range in such a way that the spectral sensor can record a spectral intensity distribution in the section of the near infra-red spectral range and/or in the section of the visible spectral range.Type: GrantFiled: December 16, 2010Date of Patent: April 29, 2014Assignee: Giesecke & Devrient GmbHInventors: Jorg Frankenberger, Wolfgang Deckenbach, Wolfgang Rauscher

Patent number: 8662278Abstract: A sensor for checking value documents, which has an illumination device for illuminating a value document, an imaging optic and a detection device. The illumination device of the sensor contains a multiplicity of light sources arranged side by side, which have emission spectra that differ from each other, and a microlens array with a multiplicity of microlenses. The microlens array and the light-source receiver are arranged so that when each of the light sources is arranged on the light-source receiver there is associated therewith exactly one of the microlenses. The measuring plane of the sensor is so close to a focal point of the imaging optic that the light of the different light sources emitted by the illumination device is largely imaged onto the same illuminated region of the measuring plane.Type: GrantFiled: December 16, 2010Date of Patent: March 4, 2014Assignee: Giesecke & Devrient GmbHInventors: Jorg Frankenberger, Wolfgang Deckenbach

Patent number: 7170080Abstract: A read-out device reads out X-rays stored in phosphor layers. To improve image quality, the read-out device is controlled such that an X-ray of a first body part, e.g. of a limb, stored in a phosphor layer is read out by the read-out device controlled in a first read-out mode, and an X-ray of a second, different body part, e.g. of a thorax, stored in the phosphor layer is read out by the read-out device controlled in a second read-out mode. The scan parameters of the read-out device set in the first read-out mode are different from the scan parameters set in the second read-out mode in at least one scan parameter. The scan parameters include, but are not limited to, the size of the pixels, the intensity and/or the width of a focus range of stimulation light on the phosphor layer, the sampling rate of a detector, and a speed of the phosphor layer in relative movement to the read-out device.Type: GrantFiled: February 9, 2006Date of Patent: January 30, 2007Assignee: Agfa-Gevaert HealthCare GmbHInventors: Robert Fasbender, Clemens Herrmann, Johan Lamotte, Stephan Mair, Horst Scherer, Jörg Frankenberger
