    摘要： The computer-implemented method for tracking the distribution of company documents carrying a graphical information added to the documents e.g. a company logo or a confidential indication comprises the steps of generating modifications of the original of the graphical information, associating each graphical information modification to a different one of a plurality of potential distribution channels for the company documents, inserting the modified graphical information in a document whose distribution has to be monitored, by rendering the graphical information in accordance with its respective modification upon generating the document by a source which is part of the respective distribution channel, comparing the graphical information of a distributed document or copy thereof with the modified versions of the graphical information for detecting the source of the distribution channel used for distributing the distributed document.

    摘要： The invention is based on the concept that by the use of radiation with a polyfrequent effective spectrum to analyse the object, a beam hardening or centre of gravity displacement of the spectrum means that the effectively active absorption coefficient or the effective active reflection coefficient of the material of the object and in particular the ratio of two coefficients to different radiation spectra is no longer specific to the material but depends on the thickness. According to the invention, this factor is taken into account to obtain a precise classification of the material of the object. To achieve this, in addition to the ratio of the absorption or reflection coefficients, one of the intensity values that is determined during the irradiation is used with the aid of reference data for the assignment to one of a plurality of predetermined materials.

    摘要： The aim of the invention is to dispense with the previous procedure, i.e. interpolation at the filter coefficients and the amplification value in order to obtain interpolated values for the intermediate audio values starting from the support points. Coding containing fewer audible artifacts can be obtained by using the performance limit derived from the masking threshold, preferably from the area below the square sum of the masking threshold, for each support point, i.e. for each parameterization that is to be transmitted, instead of interpolating the amplification value, and then performing interpolation between said performance limits of adjacent support points, e.g. linear interpolation. An amplification value can then be calculated from the determined intermediate performance threshold value at the coder end and the decoder end in such a way that the quantizing noise which is caused by quantizing and whose frequency is constant before post-filtering is done at the decoder end, lies below the performance limit or corresponds thereto following post-filtering.
