Abstract: A method and apparatus for checking luminescent value documents, in particular bank notes, with a luminescence sensor. The value document to be checked is irradiated to excite luminescence radiation, and the luminescence radiation emanating from the value document is detected with spectral resolution. Since the value document to be checked is transported past the luminescence sensor in the transport direction and is illuminated with an illumination area which extends in the transport direction, an effective measurement is possible even of value documents that emit very little luminescence radiation.

Abstract: The invention relates to a value document, such as a banknote (1), which includes one or more window zones (2A, 2B) with one for example optically active element each which rotates a polarization plane P0 of polarized light LA, LB, penetrating the window zone by a defined angle. If such value documents are stacked and polarized light penetrates the superimposed window zones, the number of stacked value documents can be determined by way of the overall rotation of the polarization plane PA, PB. The overall nominal value of a stack of banknotes can thus be determined. The window zones can have category-specific rotational characteristics for different categories or nominal values and/or can be disposed in category-specific positions in the valuable document.

Abstract: The invention relates to a printed document of value having at least one authenticity feature in the form of a luminescent substance on the basis of host lattices which are doped with one or a plurality of ions. By suitably doping host lattices with different ions, exchange interactions between clusters of ions occur which can lead to cooperative effects.

Abstract: The invention relates to a printed document of value having an authenticity feature in the form of at least two luminescent substances on the basis of host lattices which are doped with one or a plurality of ions. By systematically changing the host lattices and/or ions of the (nd)3 electron configuration a specific setting of the luminescence properties of luminescent substances is possible, the combination of which permits a multiplicity of complex new authenticity features.

Abstract: The invention relates to an apparatus and method for visually representing measuring values. The present invention starts out from the idea of veiling the visual representation of authenticity data or other measuring values by visually representing not the measuring values themselves, but camouflage data, which are formed by measuring values changed with the help of a mathematical algorithm.

Abstract: The invention relates to a sheet-shaped document of value with luminescent feature substance and the manufacturing and checking of such a document of value. The invention starts out from the idea to provide a sheet-shaped document of value (BN) with a luminescent feature substance (20, 21), which is present all over with low concentration as well as at certain partial areas with higher concentration.

Since dependent on the security category different sensor parameters are made available for the respective checking of the security feature, so as to check the same security feature in different ways, the preparing of forgeries can be prevented particularly reliably.

Abstract: The present invention relates to an apparatus for checking the authenticity of bank notes in unprotected areas. The invention starts out from an apparatus for checking the authenticity of bank notes in unprotected areas, having a sensor assembly containing a light source which produces light of a first wavelength with which the bank notes to be checked are illuminated, whereupon one or more feature substances present in and/or on the bank notes produce light of a second wavelength which is detected by the sensor assembly, and a control device which evaluates data from the sensor assembly about the light of the second wavelength and compares them with reference data to determine the authenticity of the bank notes, wherein structure and operation of sensor assembly and/or control device permit conclusions to be drawn only with difficulty on the feature substance or substances contained in the bank notes.
