Method for detection of ballistocardiogenic or respiratory-caused movements of person on motor vehicle seat, involves designing sensor as ballistographic sensor for detection of ballistocardiogenic or respiratory-caused movements of person

摘要

The method involves designing a sensor (21) as a ballistographic sensor for detection of ballistocardiogenic or respiratory-caused movements of a person (20), where the sensor emits a ballistographic signal. Another sensor (22) generates a vibration signal as noise reference for the ballistographic signal, where the ballistographically formed sensor is used as latter sensor, which is arranged in a vehicle seat (10) isolated from the vibrations against the person. An algorithm is used for minimizing noise signals of the ballistographic signals by using the vibration signal. An independent claim is included for a measuring arrangement for a vehicle seat of a motor vehicle for monitoring of heart beat or heart rate or respiratory or respiration rate, for fatigue detection and for detecting seat occupancy.
