Ultrasonic sensing array system and method

Abstract

A system and method for detecting leaks in substantially closed objects, such as automobiles, airplanes, tanks, and other vehicles, using an ultrasonic transmitter and an array of ultrasonic sensors or receivers positioned or mounted on a frame. As the objects are passed through the frame, ultrasonic amplitude readings obtained from the sensors are processed to determine if they are representative of a defective or leaking object. The position of the leak may be determined by examining the readings from individual sensors. The system is particularly well-adapted for use in detecting defects and leaks in automobiles on an assembly line without interrupting the assembly process or damaging the automobile.
