  • Method and arrangement for generating a dot matrix imprint with control using random output and probability
    Patent number: 7804620
    Abstract: In a method and arrangement for generation of an imprint with a printing device operating according to a dot matrix principle (in particular an inkjet principle), a dot pattern is provided for the imprint, with which the printing device image points corresponding to the provided dot pattern on a substrate. For at least one first image point a probability with which the image point is generated is provided. Whether this image point is actually generated on the substrate is determined in a decision step using a random generator and the probability. The image point is generated (or not) in a subsequent step dependent on the result of the decision step.

  • Print image with print elements having different security levels assigned thereto, and an apparatus and storage medium for producing such a print image
    Patent number: 6698953
    Abstract: A print image, such as for a franking apparatus, is composed of a number of elements to which different security levels are assigned. In a storage medium, and in a franking apparatus containing such a storage medium, for the print image, the image data are stored in a manner allocated to respectively different security levels.

  • Method and apparatus for examining coins
    Patent number: 5361886
    Abstract: In a method and an apparatus for examining the genuineness and the value of coins using inductive and opto-electronic devices, the coin diameter, the minting and the nature of the material are determined and evaluated within a test cycle, in which the coin is taken up, centered, clamped and turned through 360.degree.. The coin diameter is ascertained and checked by way of the angle of twist between two disks, which are disposed so that they can be twisted relatively to one another. The apparatus ensures an accurately centered and vibrationless clamping of the coin for an opto-electronic scanning and the inductive identification of the material.
