ABSTRACT:
An ultrasonic anti-collision detection and warning system adapted to be attached to a corner for warning objects approaching an intersection. The invention comprises first ultrasonic detection means having a first ultrasonic emitter which periodically emits an ultrasonic pulse at a first frequency within a first field of range, and a first ultrasonic sensor which detects an echo of said ultrasonic pulse emitted at said first frequency; second ultrasonic detection means having a second ultrasonic emitter which periodically emits an ultrasonic pulse at a second frequency within a second field of range, and a second ultrasonic sensor which detects an echo of said ultrasonic pulse emitted at said second frequency; a flexible connecting means for connecting said first and second ultrasonic detection around said corner; processor means for determining when an object enters said first field of range based upon the time of an echo received by said first sensor means, said processor means further determining when an object enters said second field of range based upon the time of an echo received by said second sensor means, said processor outputting a signal when objects simultaneously enter said first and second fields of range; and warning means responsive to said signal for outputting a warning signal in said first and second fields of range.
