  • Method and system for calibrating a structure-borne sound-sensitive acceleration sensor and method for correcting the measuring signals of a structure-borne sound-sensitive acceleration signal
    Patent number: 11812215
    Abstract: A method for calibrating a structure-borne sound-sensitive acceleration sensor with the aid of at least one microphone. For this purpose, the acceleration sensor is situated in an intended position on the body of a user. Furthermore, at least one acceleration sensor signal and at least one microphone signal are detected, the at least one acceleration sensor signal and the at least one microphone signal being synchronized and having been caused by a vocalization of the user. A frequency analysis of the acceleration sensor signal and a frequency analysis of the microphone signal are carried out. A frequency-dependent correction function for correcting the transmission function of the acceleration sensor is ascertained on the basis of the frequency analyses of the acceleration sensor signal and the microphone signal.

  • Method for operating a micromechanical inertial sensor
    Patent number: 11536742
    Abstract: A method for operating a micromechanical inertial sensor, including: translating an acceleration into a deflection of two detection electrodes that are displaced in opposite directions; ascertaining a difference in the spacing of the two detection electrodes; converting the difference in the spacing into an acceleration value using a scaling factor; and applying a linearization process to the acceleration value.
