SELF-TESTING FUNCTIONAL CHARACTERISTICS OF ULTRASONIC SENSORS |
摘要 |
Functional characteristics of an ultrasonic element are self-tested by, in various embodiments, causing the ultrasonic element to emit an ultrasonic signal; detecting the emitted ultrasonic signal substantially simultaneously with its emission; and verifying proper operation of the ultrasonic element based on comparison between a detected ultrasonic signal parameter and a reference parameter. |
