First Claim
Patent Images
1. A controlling method used in an ultra-sound sensor, the method comprising:
- measuring a distance between an obstacle and the ultra-sound sensor;
determining whether the distance is smaller than a distance threshold; and
stepping down a driving voltage of the ultra-sound sensor if the distance is smaller than the distance threshold.
