GPS Already Exist on 1930

Long before people understand by a guide device in the car sort of global positioning system (GPS), a product called Iter Avto already made in Spain in 1930. Don’t imagine the sophisticated like in-car devices that rely on satellites such as made Alpine (1981) or Etrak (1983), orbe asked to designate the road with our voices (the latter is recognized even make trouble). Iter Avto much simpler, just rely on the paper roll as a walking map.

Iter Avto actually more like a map in the form of a roller which moves with the motion of the car. Map rotates in the middle, like a screen. Then the principle of rotation similar to the speedometer which moves rely on the wheels. Iter Avto was placed just as people today put a global positioning system (GPS), which is in the middle under the dash.

A roll of paper illustrated the path and name of the dots and then pinned in it. Its use depends on the location that is being addressed. If the user wants go to London for example, they must install a roll of special maps of London. If you move, have to change reels.

The existence of any Avto Iter is unclear, the producer and creator names like lost by time.

However, if we talk "who the first time made", the guide on the road already made similar in England, even 10 years earlier or the range of 1920. The device, called Plus Fours Route finder is even more simple. Shaped like a wristwatch. The principle works the same as the Iter Avto, using the roll map. But the moving is manual by playing round with your fingers.

Magic Cloak For Tank

Scientists at BAE Systems, Sweden, working on the development of a magic cloak for tank. However, this cloak is not as disappear cloak like Harry Potter's cloak, but for the needs of camouflage military vehicles.

Later, this device will be able to protect the tank from heat-seeking rocket attacks that often chase. Research project named Adaptive this will be tested in the next two years.

Military invisibility cloaks are composed of hexagonal-shaped pieces of metal for an adult's palm. These pieces of metal can be heated or cooled quickly to camouflage buildings, ships, or low-flying helicopters. To envelop a small tank, it takes about 1,000 pieces of metal.

The device is equipped with a scanner to "read" the environment. Then scan patterns reproduced on a metal panel in the hexagonal shaped hull tank (or other objects). Furthermore, the infrared image is displayed to allow tanks blend with the surrounding environment and make the enemies see it as a car or even a cow.

According to Peter Sjolund, head of research, this technology works like a thermal screen. Besides bringing a collection of images that have been stored, the device can also take pictures that fit with the surrounding environment if necessary. Further development could be even more sophisticated.
