ABSTRACT:
The ultrasonic device which is sensitive to a selectably defined range for giving warning to a vehicle operator while backing which indicates visually an obstruction substantially out of range, close to range and within range coupled with an in range audio alarm giving an intermittent tone at a defined pulse rate which rate approaches non-pulsating as the object approaches within 25% of the selected range. A convex reflector of a defined radius in conjunction with angularly upright baffles disposed on the convexity is coupled to the transmitting/receiving transducer to generate an ultrasonic beam which encompasses objects anywhere in the range area adjacent to the vehicle's rear edge.
