  • Method and ultrasonic sensor for determining the height of objects disposed on a conveying device
    Patent number: 8096183
    Abstract: The present invention relates to a method for determining the height of objects disposed on a conveying device, in which an ultrasonic sensor positioned in a specific relationship to the conveying device repetitively transmits ultrasonic pulses directed toward the conveying device and any objects disposed thereon to be detected, wherein the ultrasonic pulses are then reflected from a surface of the conveying device or from surfaces of the objects to be detected and are detected by the ultrasonic sensor, wherein from the moments of transmission and moments of detection of the ultrasonic pulses, delay times of the ultrasonic pulses are determined and the height of an object surface relative to the surface of the conveying device is determined from the delay times of the ultrasonic pulses reflected from a surface of an object.
