The idea is to incorporate a microphone in the side view mirror in a car to pick up the horn frequencies of vehicles following the car.
Sometimes, when the door windows are up, and music is playing, it becomes difficult to hear the horn. The microphone gets activated when the window glasses are up and sends the signal to a vibratory pad on the steering, which will alert the driver about another vehicle following.
He has many other ideas as well like a remote that takes energy from TV light or any other natural/artificial source of light, and a luggage carrier on the top of automobiles with a rotatory base so that one needs just to rotate the carrier to pick up any luggage on any side.
He is 2010 IGNITE Award recipient and the patent (3058-MUM-2010) for his invention is filed by NIF.
