Patent number: 11043057Abstract: A method for checking of magnetic properties of value documents with the aid of a magnetic sensor comprises a measuring sensor row having a plurality of magneto-sensitive measuring sensor elements, as well as at least one further magneto-sensitive sensor element which is arranged behind the measuring sensor elements and has a greater distance from the transport plane of the value document than the measuring sensor elements. By means of the further sensor elements, correction signals are detected at correction measuring points of the value document, which are disposed on the same measuring line as the measuring points.

Patent number: 10981406Abstract: A security feature for protecting valuable documents, in particular for ensuring the authenticity of valuable documents, comprises a luminescent pigment which has a host lattice doped with a first luminophore and a second luminophore, with an excitation energy of the first luminophore being transferable to the second luminophore. However, in the case of the luminescent pigment according to the invention, the excitation energy is not transferred completely from the first luminophore to the second, but rather only partially. The incomplete transfer of the excitation energy is achieved by selecting suitable amount-of-substance fractions of the first and the second luminophores on the luminescent pigment. As a result of the incomplete transfer of the excitation energy, the luminescent light that is emitted by the luminescent pigment also has, in addition to a luminescence peak of the second luminophore, a luminescence peak of the first luminophore.Type: GrantFiled: December 21, 2011Date of Patent: April 20, 2021Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Johann Kecht, Kai Uwe Stock
