Abstract
This invention relates to a new and useful system and method of ultrasonic detection for use on in the monitoring of the danger zone of a vehicle. The system comprises at least one sensor, an analog and digital integrated circuit, a power driver and a microprocessor. The microprocessor is programmed to control the sensors, to receive a plurality of signals from the sensors, establish and store an initial reference image, monitor a second plurality of signals received from a continuous scan of the sensors, establish a data set for the second plurality of signals, compare the data set with the initial reference image and return an alarm output if a variation is detected.
