    Abstract: An apparatus for correcting an input signal is configured for receiving the input signal, the received input signal comprising a series of input values. The apparatus is configured for matching a series of template values to the series of input values by warping the series of template values and the series of input values relatively to each other so as to assign one or more template values to one or more input values, wherein the series of template values represents an approximation of a noise signal that is expected to be comprised in the input signal. The apparatus is configured for obtaining a series of corrected input values based on a mismatch between the input values and their respective assigned template values. The apparatus is configured for providing a corrected signal based on the series of corrected input values.

    Abstract: An apparatus for analysing the particulate matter content of an aerosol includes an aerosol chamber configured to receive an aerosol, the particulate matter content of which should be analysed, at least one ultrasonic generator configured to produce ultrasonic waves in the aerosol received in the aerosol chamber, an ultrasonic detector configured to detect ultrasonic waves produced by the at least one ultrasonic generator in the aerosol, and an evaluator having a data exchange communication link with the ultrasonic detector and configured to ascertain the matter content on the basis of signals output by the ultrasonic detector. The ultrasonic generator and the ultrasonic detector are positioned relative to one another such that a path length to be traversed by ultrasonic waves between the ultrasonic generator and the ultrasonic detector is less than 1 cm.

    Abstract: A photoacoustic sensor comprises an emitter for emitting electromagnetic radiation at a first wavelength and electromagnetic radiation at a second wavelength, wherein the first wavelength is for photoacoustically detecting particulate matter in a measurement cavity and the second wavelength is for photoacoustically detecting the particulate matter and at least one target gas in the measurement cavity. The photoacoustic sensor further comprises an acoustic transducer for transducing a first acoustic signal into a first sensor signal depending on an interaction of the electromagnetic radiation at the first wavelength and the particulate matter, and for transducing a second acoustic signal into a second sensor signal depending on an interaction of the electromagnetic radiation at the second wavelength with the particulate matter and the at least one target gas.

    Abstract: In accordance with an embodiment, a microelectromechanical transducer includes a displaceable membrane having an undulated section comprising at least one undulation trough and at least one undulation peak and a plurality of piezoelectric unit cells. At least one piezoelectric unit cell is provided in each case in at least one undulation trough and at least one undulation peak, where each piezoelectric unit cell has a piezoelectric layer and at least one electrode in electrical contact with the piezoelectric layer. The membrane may be formed as a planar component having a substantially larger extent in a first and a second spatial direction, which are orthogonal to one another, than in a third spatial direction, which is orthogonal to the first and the second spatial direction and defines an axial direction of the membrane.

    Abstract: A MEMS device includes a MEMS sound transducer, and control circuitry. The control circuitry includes a supply signal provider for providing a high-level supply signal and read-out circuitry for receiving an output signal from the MEMS sound transducer, and a switching arrangement for selectively connecting the MEMS sound transducer to the supply signal provider, and for selectively connecting the MEMS sound transducer to the read-out circuitry based on a control signal. The control circuitry provides the control signal having an ultrasonic actuation pattern to the switching arrangement during a first condition TX of the control signal, wherein the ultrasonic actuation pattern of the control signal triggers the switching arrangement for alternately coupling the high-level supply signal to the MEMS sound transducer.
