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.

Carl Wilhelm Scheele

Died 21 May 1786 at age 43 (born 9 Dec 1742). (also Karl) Swedish chemist who discovered oxygen in 1772. Scheele, a keen experimenter, worked in difficult and often hazardous conditions. In his only book, Chemical Observations and Experiments on Air and Fire (1777), he stated that the atmosphere is composed of two gases, one supporting combustion, which he named "fire air" (oxygen), and the other preventing it, which he named "vitiated air" (nitrogen). Due to delay in his publication, he lost priority to Priestley's discovery of oxygen in 1774. Scheele discovered many substances, such as chlorine (1774), manganese (1774), tungsten (1781), molybdenum (1782), glycerol, hydrocyanic (prussic) acid, citric acid, hydrogen sulphide and hydrogen fluoride. He also discovered a process resembling pasteurization.
