Abstract
An ultrasonic detection system for signaling the presence of an object in one of n linear fields in the path of motion of a person or vehicle. Ultrasonic signals are transmitted by transducers. The linear distance in the path of motion is divided into n linear fields. A unique warning signal such as a voice message, informs the operator of the system of the field in which the object is positioned. The operator of the system may select one or any combination of the fields and may alter the length of any or all fields.
