Small discoveries of science also bring huge changes in our lives. In this era of science, research is being done every day, many things are being discovered. Some inventions directly change our way of life, and some invention indirectly affects us. Today we will know about some inventions.
- The control of the sensor that controls the machine
The US armored helmet has changed greatly over the years. In the First World War, the M1917 / M1917A1 helmets used by US troops were known as "Dabway" or "Dispun", which protected the soldiers' head. During the Second World War in 1941, the helmet was replaced by the M-1 "steel pot" helmet. In the 1980s US Helicopter Helmet was further improved by the Kevlar 29 missile fiber. The helmet used in the future may have more protection and convenience.
Currently a group of Arizona State University researchers is trying to build a helmet for US military under the US Defense Advanced Research Projects Agency, which will be able to control the minds of the soldiers through sound waves. It will have many effects on the battlefield. Using a controller, the army can stimulate some parts of the brain by stimulating ultra sound pulse timely. Besides, they can also use it for release of stress, and may even be able to forget pain, which does not have to use anti-drug medicines.
- Pencil from the paper
According to the United States Clean Air Council's survey, United States has 21 million metric tons of paper business each year, and an average of £ 175 is required for each American. So, consciously writing the recycling program of various offices for the use of paper, "please think before you print".
So three inventors of China have discovered a new type of device, which will make the paper a pencil. When some papers are inserted through a hole in the machine, the device will then turn it into a pencil. The device has some glue and some leads. This gum adds a pencil to the lead pencil, and the machine will draw a beautiful pencil on the other side. This will prevent the waste of paper and the money to buy a pencil or pen will also be saved.
- Humans fly in the sky
Have you ever wanted to fly in the sky like a bird? Such people may be few, whose life does not want to fly like a bird's wings once. To satisfy that desire, a team of researchers is thinking of inventing a flying suite, which is very similar to a bird's wings.
Like bats, mammals and people have many similarities in some areas, so fans like bats like feathers are useful for people to fly. Like a suite, this device has two fan, flexible and rigid components that users will need during the flight. When landing down from top to bottom, the user needs to adopt a little strategy. He has to do something like gravity, or walk down the bicycle or use the rollerblading technique. But the question is, will it really work?
