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.
Others, like the tiger moth, hear the bat and emit a jamming signal in the ultrasonic frequency spectrum.
A wave sensor with canted ultrasonic beams also measures wave direction.
Researchers theorize that there could be an evolutionary explanation for the frog's ultrasonic hearing.
She successfully destroyed two dozen hostile ghosts with ultrasonic sound waves and laser grids.
Static and dynamic obstacle detection is supplemented by an array of ultrasonic sensors.
Then, using an electronic compass and ultrasonic sensors, it cuts the area about 10 times, ensuring a minimum of missed patches.
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.
Once the blade struck something, it would vibrate at an ultrasonic frequency, making the gash even bigger.
