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.

Barbed wire

In 1873, farmer Joseph F. Glidden applied for a patent on barbed wire. The barbs were cut from sheet metal and were inserted between two wires which were twisted considerably more than with today's common design. This product would transform the West. Before this innovation, settlers on the treeless plains had no easy way to fence livestock away from cropland, and ranchers had no way to prevent their herds from roaming far and wide. Glidden's barbed wire opened the plains to large-scale farming, and closed the open range, bringing the era of the cowboy and the round-up to an end. Glidden eventually received five patents and is generally considered the inventor of barbed wire.Image: detail from patent application diagram.
