All these products are designed and made by China.
One of the interesting products on display is a small satellite used for the Olympic Games called Beijing No. 1. Its sensor3 measures 4 meters and it is considered as one with the highest resolution among all transmission type micro satellites made in China. The satellite can send 32-meter-long spectrums and can cover an area of 600 kilometers. It has the largest width among the same type of satellites produced in the world. The satellite was launched into space in 2005 and can work in space for at least 5 years. It will be used to monitor some key areas in Beijing. It is said that the satellite can pinpoint4 any place to monitor whenever it wants. It is also the first small satellite that is made for the Olympic Games.
Another novelty exhibited is a device that can distinguish human faces. The inventor of the device, Ma Xin, a Ph.D at the Chinese Academy of Sciences, said that the new device will make it impossible for criminal suspects to disguise themselves among the crowd. The new device will be installed in the Olympic stadiums and gyms, Olympic Village, and athletes apartments.
