Patent number: 12384190Abstract: A value document with a carrier element and a foil element arranged in a partial region of the carrier element. The carrier element has, at least in the partial region, a luminescence marker which is adapted to give off luminescence radiation which has at least a first wavelength and a second wavelength in each case in the infrared spectral region. The foil element has a reflection layer and a spectral selection layer. The selection layer is arranged between the carrier element and the reflection layer. The reflection layer is configured to reflect infrared radiation and the selection layer is configured to spectrally selectively inhibit transmission of infrared radiation. The inhibition of the transmission of the first wavelength and the inhibition of the transmission of the second wavelength differ by at least 10%.Type: GrantFiled: June 2, 2021Date of Patent: August 12, 2025Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Henning Geiseler, Thomas D.

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
