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.

Abstract: The invention relates to a method for providing hypertext data through a hypertext server on a portable data carrier for a terminal connected to the portable data carrier, and to an accordingly adapted portable data carrier. The hypertext server receives a hypertext query of the terminal and thereupon provides hypertext data relating to the hypertext query. The hypertext server then sends the provided hypertext data as a hypertext response to the terminal. The method is characterized in that upon the providing of the hypertext data at least one hyperlink contained in the hypertext data is checked and the checked hyperlink is contained in the hypertext response.

Abstract: The present invention relates to a dewatering screen for manufacturing paper having multi-level watermarks, having a carrier mold (54) that exhibits, in a fractional region, a multi-level relief (30) in the form of the watermark to be produced. According to the present invention, it is provided that the multi-level relief is formed by an injection-molded, perforated (40) watermark insert (30).
