  • Patent number: 9336640
    Abstract: The invention relates to a security element for securing documents of value. Along the security element a portion of a magnetic coding with first and second coding elements is arranged. The coding elements are arranged along a predetermined direction, wherein the first coding element continuously has along the predetermined direction a first magnetic region with a first coercive field strength and the second coding element has at least one first gap region and one second magnetic region with a second coercive field strength. At least one of the first magnetic regions is directly adjacent to at least one of the second magnetic regions. The sum of the lengths of the directly adjacent first and second magnetic regions amounts to a maximum of 8 mm.

  • Patent number: 9171411
    Abstract: A method for the compensation of disturbances upon magnetic measurements on value documents, in which a sensor having several measuring tracks for generating measurement signals is employed, in which for each value document a specified number of data records is generated, the value document not being captured by at least one of the measuring tracks during the measurement, wherein from the measurement signal of the at least one measuring track there is ascertained a value for the quantity of a disturbance present in the region of the sensor during the measurement on the value document, and a compensation of the deviations of the measurement signals of the measuring tracks capturing the value document, which deviations are caused by the disturbance present during the measurement, is carried out by means of said ascertained value for the quantity of the disturbance.

  • Patent number: 8910869
    Abstract: A method of checking value documents having a security element with a plurality of magnetic areas, including a high-coercivity magnetic area, a low-coercivity magnetic area and a combined magnetic area, which contains both the high-coercivity and the low-coercivity magnetic material. When all magnetic areas have been magnetized in a first direction, second magnetization is performed, which involves only the low-coercivity magnetic material being remagnetized parallel to the first magnetization in the opposite direction, but the high-coercivity magnetic material remaining oriented in the first direction of magnetization. Next, first magnetic signals from the security element are detected using a first magnetic detector, and second magnetic signals are detected using a second magnetic detector. The magnetic signals are used to identify each magnetic area of the security element as a high-coercivity, a low-coercivity or a combined magnetic area.

  • Patent number: 8837804
    Abstract: The invention relates to a method and apparatus for recognizing forged value documents, for example composed forgeries which are assembled from parts of different value documents. In the inventive method, the signal intensity of a measuring signal is determined at a plurality of measuring points on a value document. For one or more selected groups of measuring points which are disposed in particular along certain directions on the value document there are determined gradient values of the signal intensities. The gradient values of a group are subsequently linked to form a connection strength of the group which provides a quantitative statement about the extent to which a large gradient value exists consistently within the particular group. From a relatively great connection strength there can be inferred the presence of a separating line in the area of the selected group of measuring points.

  • Patent number: 8740094
    Abstract: The invention relates to a security element for protecting documents of value, which has magnetic material. A portion of a magnetic coding is arranged on the security element, which coding consists of several magnetic areas and several gap areas. The portion of the magnetic coding is arranged in a predetermined direction along the security element, for example perpendicularly to a transport direction of the security element or document of value through a magnet sensor. Concerning the length of the magnetic areas and of the gap areas of the magnetic coding, certain length conditions are predetermined, which are chosen in dependence on the magnet sensor employed.

  • Patent number: 8511561
    Abstract: Scanning apparatuses for scanning bar codes applied to documents have a reflector arrangement having either a variable reflection element or a light guide system. The reflection element or light guide system serves to deflect the beam path of the electromagnetic radiation emitted by a radiation source or an illumination device in the document plane along a line substantially perpendicular to the feed direction of the document, or to capture it, and to relay it to a detector.

  • Publication number: 20120118961
    Abstract: Value documents including a security element having magnetic material for securing the value documents. Along the security element, for example along a longitudinal direction of the security element, there are disposed one or more magnetic areas and one or more gap areas. The extension of the magnetic areas or the gap areas along the security element is preferably chosen so that the magnetic signals of adjacent magnetization steps interfere constructively with each other when transported past the magnetic sensor.

  • Patent number: 7860293
    Abstract: Forged bank notes are no longer reliably distinguishable from bank note originals (BN) on the basis of their luminescent fibers. According to the invention, the excitation of the fibers to luminescence is effected by means of excitation radiation (S) from the restricted wavelength range from 600 to 640 nm or from 520 to 550 nm, since the forgeries do not luminescence in this range but the originals luminescence red. Detection is therefore effected in the wavelength range from 640 to 700 nm.

  • Patent number: 7829869
    Abstract: The invention relates to a method and an apparatus for recognizing forged documents of value, wherein the documents of value are illuminated with clocked excitation light of a light source. Within the bright phase of the excitation light a first luminescence intensity is detected, within the dark phase a second luminescence intensity. Because of the afterglow of the light pulses there is a residual fluorescence, which distorts the luminescence intensity in the dark phase. By linking the second luminescence intensity with the first luminescence intensity, e.g. by subtracting a scaled first luminescence intensity, a corrected second luminescence intensity is determined, which substantially corresponds to the phosphorescence signal of the document of value.

  • Patent number: 6927571
    Abstract: The invention relates to apparatus for examining magnetic properties of objects, in particular sheet material, such as bank notes (20). The apparatus comprises a magneto-optic layer (10) whose optical properties are influenceable by the magnetic properties of the sheet material (20), a light source (11) for producing light that is coupled into the magneto-optic layer (10), and a detector (13) for detecting light that is transmitted and/or reflected by the magneto-optic layer (10). For reliable examination of the magnetic properties of sheet material it is provided that the direction of propagation of the coupled-in light extends parallel to a base surface (9) of the magneto-optic layer (10). The invention permits the magnetic properties in particular of sheet material with areas emitting very weak magnetic fields to be examined with very high sensitivity and reliability.
