ABSTRACT:
An all-weather digital distance measuring and signalling system for a vehicle specifically intended for accurately measuring distances of obstructions, such as behind a truck as it is being backed up. An array of transducer devices having independent sending and receiving capabilities are mounted on a support frame, such as a rear bumper. A pulsed signal emanating from a transistor amplifier circuit is timed as it is converted to an ultrasonic wave signal by each transducer device, simultaneously emitted and received by said transducer devices, and returned as a pulsed signal. Said signal being returned after bouncing back from an obstruction and the time of said return being converted into a distance value by digital converter circuitry. Said digital converter circuitry in turn sends said signal to a digital display device. In addition to displaying a digital read-out, said display device emits a periodic beeping sound and flasher tied to the signal and increasing in speed until a distance of 1.9 feet is acquired, at which time the beeper becomes a solid tone.
