Mounted on the rear number plate and automatically activated in reverse gear, two 'ultrasonic' sensors can detect obstacles up to 100 cm behind the car.
Coupled with the use of electromagnetic and 'ultrasonic' detectors, excavations to find utilities could be faster and safer.
Warwick also hopes to wire himself up to a 'ultrasonic' sensor, used by robots to navigate around objects, to give himself a bat-like sixth sense.
A wave sensor with canted 'ultrasonic' beams also measures wave direction.
Occupancy sensors come in two basic types: infrared and 'ultrasonic' .
The team bombarded this liquid with sound waves tuned to 'ultrasonic' frequencies that caused wide variations in pressure in the fluid.
