Patent number: 11830329Abstract: A method for testing a value document having a luminescence feature involves guiding the value document past a test sensor in a transport direction. A scanning sequence occurs that repeats itself multiple times upon guiding the value document past the test sensor. The method involves irradiating a test region of the test sensor such that the test radiation is arranged to be remitted by the value document at least partially in a detection spectral range of the test sensor. Excitation radiation is arranged to cause an emission radiation of the luminescence feature in the detection spectral range. The method further involves scanning at least one location-dependent remission spectral value in the test region in the first irradiation phase, irradiating the test region only with the excitation radiation in a second irradiation phase, and scanning at least one location-dependent emission spectral value in the test region after the first irradiation phase.Type: GrantFiled: December 21, 2016Date of Patent: November 28, 2023Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Erich Kerst, Thomas Happ

Patent number: 11823522Abstract: The present invention relates to a method, a sensor, a sensor unit and a bank-note processing machine for checking the completeness and/or authenticity of value documents. A value document comprises at least one machine-readable feature substance in at the least two locations. According to the method, the value document is excited at least locally at measuring locations. Furthermore, a feature intensity with respect to the machine-readable feature substance is captured location-resolved at several different locations of the value document. The location-based feature intensities are classified location-based with the help of a threshold value. Furthermore, location-based limits of a location distribution to be expected of the machine-readable feature substance are determined. Finally, a location-based distribution of the classified feature intensities is assessed.Type: GrantFiled: December 21, 2016Date of Patent: November 21, 2023Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Wolfgang Rauscher, Erich Kerst, Thomas Happ

Publication number: 20230274599Abstract: A sensor and a method for checking value documents are provided, each having a luminescent sheet-like substrate and a luminescent feature applied to a partial surface of the substrate, and to a value document processing apparatus. From the spectral vectors obtained for a plurality of measurement points and characterizing the intensity of the luminescent radiation of the value document detected in at least two spectral ranges, substrate intensity values and feature intensity values are determined, based on which a pure substrate mask is determined, which contains only those measurement points which reliably lie outside the feature. From the spectral vectors of the measurement points contained in the pure substrate mask, a mean substrate vector is determined, based on which corrected substrate intensity values and corrected feature intensity values and/or a spectral signature of the substrate and/or of the feature are or is, respectively, determined from the spectral vectors.Type: ApplicationFiled: July 8, 2021Publication date: August 31, 2023Inventors: Wolfgang RAUSCHER, Wolfgang DECKENBACH, Julia DANHOF, Thomas HAPP
