The invention relates to a method for detecting a state of wear of a cardiac support system. The method comprises a read-in step and a determination step. During the read-in step, a sensor signal () representing an operating state of the cardiac support system is read in. During the determination step, a wear signal () is determined using the sensor signal () and a comparison rule (). The wear signal () represents the wear condition.

A micromechanical sound transducer system includes a substrate that includes (a) a cavity with a cavity edge area, (b) a front side, and (c) a rear side; a piezoelectric vibrating beam that is elastically suspended on the front side and that extends across the cavity; and, for the piezoelectric vibrating beam, a respective deflection limiting device that is on a front edge area of the respective vibrating beam and that is configured to limit a deflection of the respective vibrating beam to a limiting deflection by causing the respective front edge area of the respective vibrating beam to interact with the cavity edge area or an opposing front edge area of another vibrating beam.

A method for operating an analog-to-digital converter to convert a signal includes calculating a signal parameter in a spectral sub-range of the signal to be converted. The spectral sub-range includes a frequency range of a potential sampling frequency range of the analog-to-digital converter, which does not include frequencies of at least one other sub-range of the sampling frequency range. The method further includes determining a sampling frequency of the analog-to-digital converter by using the signal parameter and operating the analog-to-digital converter using the determined sampling frequency.

A method for processing a signal includes reading in a signal and filtering the signal using a first number of band-pass filters in order to obtain one band-pass filtered signal per band-pass filter. The first number of band-pass filters is configured to each allow distinct frequency ranges of the signal to pass. The method further includes calculating at least one signal parameter each from the plurality of band-pass filtered signals. The method further includes performing analog-to-digital conversion of the plurality of band-pass filtered signals or signals derived therefrom using a plurality of signal parameters such that a second number of analog-to-digital converters used to perform the analog-to-digital conversion is less than the first number of band-pass filters used to filter the signal.
