CAPTEUR ULTRASONORE AYANT UN DISPOSITIF D'EMISSION ET UN DISPOSITIF DE RECEPTION D'ONDE ULTRASONORE |
摘要 |
<p>An ultrasonic sensor for detecting an object includes: a substrate; a transmission device for transmitting an ultrasonic wave; a plurality of reception devices for receiving the ultrasonic wave; and a circuit for processing received ultrasonic waves, which are received by the reception devices after the ultrasonic wave transmitted from the transmission device is reflected by the object. The transmission device and the reception devices are integrated into the substrate. The dimensions of the sensor are minimized, and detection accuracy of the sensor is improved.</p> |
