  • Publication number: 20090008925
    Abstract: A security device for the identification or authentication of goods is described. It comprises a stochastic pattern comprising structures having an average lateral structure size d and arranged such that an image of at least a part of the security device, when treated through 2D Fourier transformation and calculation of a corresponding Power Spectrum Density, may lead to a peak, in a spatial-frequency domain, having a position in this domain correlated to d and a size distribution value w which, when inverted, is correlated to a size distribution of the structures. The value w according to the invention is smaller than 2/d, so that when directing a coherent light beam on at least part of the structures a ring-shaped scattering speckle pattern is formed, on the basis of which d and w may be calculated to implement identification or authentication of the device.

  • Patent number: 7400149
    Abstract: After disconnection from the power supply system, a discharge characteristic of the no-load voltage is recorded automatically by means of a control unit across a discharge resistance during a stage-by-stage discharge cycle from a charged battery which is being operated for the first time on the power supply system. This stage-by-stage discharge cycle is repeated at times which can be defined, in order to record an instantaneous discharge characteristic of the no-load voltage, and an alarm no-load voltage is determined from the instantaneous discharge characteristic of the no-load voltage from a previously defined reserve time and from the final discharge voltage as determined in the first measurement, which alarm no-load voltage represents a measure of the energy which in each case still remains in the battery, and on reaching which during operation on the load, an alarm is produced for the operator of the power supply system.
