Back-Up Sensor

Inventor of the automobile back-up Sensor -
I bet you think it was Ford, maybe GM, how about Chrysler? No, then how about Mercedes Benz?
No, not at all, it was a Chinese farmer!
Most of the newest cars have a Back-Up Sensor that warns the driver before the rear bumper actually comes in contact with something. Most people probably think that this valuable feature came out of the minds of great engineers, but it was recently disclosed that the concept was first developed by a Chinese farmer. His invention was simple and effective. It emits a high-pitched squeal when the vehicle backs into something.

Edison patent

In 1888, Thomas A. Edision, with co-inventor Ezra T. Gilliland were granted a patent for "Railway Signaling" (U.S. No. 384,830). The invention related to signalling systems for communicating between stations and moving trains by induction from the telegraph wires to the roofs of the cars. In such a system, transmitters were vibrators operated by keys to send signals upon the line, and receivers were telephone receivers connected to the ground. The patent was for an innovation to increase the quickness, rapidity and clearness of the vibrations. By making the transmitted vibrations as short and distinct as possible, they may be more clearly reproduced at the receiver.
