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.

Balfour Stewart

Born 1 Nov 1828; died 19 Dec 1887 at age 59. Scottish meteorologist and geophysicist who studied terrestrial magnetism and radiant heat. His researches on radiant heat contributed to foundation of spectrum analysis. He was the first to discover that bodies radiate and absorb energy of the same wavelength. In meteorology, he pioneered in ionospheric science, making a special study of terrestrial magnetism. He proposed (1882) that the daily variation in the Earth's magnetic field could be due to air currents in the upper atmosphere, which act as conductors and generate electrical currents as they pass through the Earth's magnetic field. He also investigated sunspots. In 1887, he suffered a stroke while crossing to spend Christmas at his estate in Ireland and died soon after at the age of 59.«
