- a combination of the transformed signals and the static characteristics can be displayed.
- the common intention is, in particular, to compare the actual measurement signal with the reference signal state in the context of the pattern recognition, wherein the reference signal is generated or output from information from one or more neighboring spindles a memory can be read. This is done in particular on the basis of specific features which are generated from the signal and combined in a feature tool based on a statement about the similarity of the signals in question.
- control modules 10 have the abovementioned (computational) means in order to evaluate the operating states. These then send the result to the assigned section module 1 1 for further processing.
