The system comprises a micro controller which comprises a main controlling unit, a driving signal generating unit, a signal receiving unit, and a residual vibration detecting unit. The driving signal generating unit is controlled by the main controlling unit so as to transmit a first sensor driving signal to the ultrasonic sensor, thereby making the sensing head to output an ultrasonic wave. In case of the transmission of the first sensor driving signal is stopped, the residual vibration detecting unit is enabled to apply a residual vibration measuring process to the ultrasonic sensor. Consequently, according to a residual vibration signal received from the residual vibration detecting unit, the main controlling unit is able to judge whether there is at least one foreign body attached on the surface of the sensing head."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Superficial foreign bodies detecting system for ultrasonic sensor","description":"A superficial foreign bodies detecting system for ultrasonic sensor is disclosed.
