  • Patent number: 10002267
    Abstract: A method for checking value documents includes checking a security element having a plurality of magnetic regions, including a high-coercivity magnetic region, optionally a low-coercivity magnetic region and optionally a combined magnetic region which contains the high-coercivity as well as the low-coercivity magnetic material, and optionally a soft-magnetic magnetic region. After the magnetization of all the magnetic regions in a first direction, first magnetic signals of the security element are detected with a first magnetic detector. Subsequently, a second magnetization is performed wherein the low-coercivity magnetic material is remagnetized anti-parallel to the first magnetization, but the high-coercivity magnetic material remains aligned in the first magnetization direction. Second magnetic signals are detected with a second magnetic detector.

  • Patent number: 9910122
    Abstract: The invention relates to a magnetic sensor which is designed for checking value documents, and to a method for calibrating the magnetic sensor. The magnetic sensor has different calibrating parameters for hard-magnetic and soft-magnetic magnetic regions, with which parameters the magnetic sensor can correct the detected magnetic signals of a value document, in order to compensate the magnetic sensor's measurement deviations in dependence on the type of the respectively detected magnetic region. For calibration, the magnetic sensor detects calibration measurement values of a calibration medium which is transported past the sensor. By means of the calibration measurement values the function of the magnetic sensor is tested.

  • Patent number: 9911074
    Abstract: The invention concerns a security element having a magnetic coding consisting of magnetic coding elements. At least one of the magnetic coding elements has a grid-shaped magnetic region which is formed by a plurality of mutually parallel grid strips made of magnetic material which respectively have a magnetic anisotropy. The grid strips lead, through their magnetic anisotropy, to the magnetization direction of the coding element being able to differ from the direction of the applied magnetic field. Since the resultant magnetic signals that the grid-shaped magnetic regions deliver cannot be simulated by conventional magnetic regions, said coding elements increase the anti-forgery security of the security element.

  • Patent number: 9685019
    Abstract: A method or apparatus for examining a security element of a value document involves at least one optical property of the security element influenceable by a magnetic field. The value document is transported through a magnetic field which is inhomogeneous transversely to the transport direction and/or is changed time-dependently. An image of at least one portion of the value document having the security element is captured and image data describing the image are formed. The optical properties of the security element are influenced by the magnetic field, and the image data is checked whether they have a location dependence transverse to the transport direction corresponding to the location dependence of the magnetic field and/or have a location dependence in the transport direction corresponding to the time dependence of the magnetic field.

  • Patent number: 9183421
    Abstract: A testing configuration for testing a security document includes a security element, having a high-coercivity magnetic material and a low-coercivity magnetic material, a device comprising such a test configuration and to a relevant test method. The high- and low- coercivity magnetic materials of the security element are magnetized in a first direction by the interaction of first and second magnet pair units, and subsequently the low-coercivity magnetic material is remagnetized in a second magnetization direction by means of the second magnet pair unit. The magnet pair units are arranged with respect to one another in such a closely adjacent manner along the transport path of the security document that the first magnet field strength is greater than the magnet field strength provided by the first magnet pair unit alone and is greater than the magnet field strength provided by the second magnet pair unit alone.

  • 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: 8695397
    Abstract: The invention relates to a method for calibrating a sensor which is configured for checking value documents. The sensor senses measurement signals of a calibration medium which is transported past the sensor. From the sensed measurement signals there are determined reference data of the calibration medium and there is moreover determined a transport property of the calibration medium, e.g. the transport speed or the transport position of the calibration medium. From the transport property there is ascertained at least one correction value which is employed for correcting the sensed reference data of the calibration medium. After the calibration, the corrected reference data are compared with target data of the calibration medium. Optionally there is then effected an adjustment of the sensor using the corrected reference data.
