The Stark Hand
It is anartificial hand which is specially designed for NASA. It moves easily and works like an electronic hand. The story behind the invention is like this:
A boy named Dave Vogt, when born, does not have his left hand by nature. A scientist named Stark created an electronic hand for him and the hand has three knuckles (Which have a joint of a finger when the fist is closed).
These knuckles can be bent according to the wish of the Vogt and he may catch the things easily. Interesting thing is that the Vogt may open all of his fingers freely by the moment of his shoulder that triggers a lever to extract. This artificial hand is really magical, because the Vogt may grip an egg with politeness and as well as drag a heavy chair.
When Vogt used this hand a ball was thrown towards him, he caught the ball with his artificial hand and certified that he is no more disabled and may do his work like a normal person.
A company named Edison Nation helps the inventors to develop their ideas by selecting the electronic hand for commercial production.
Dynamic Eye Sunglasses
When a doctor Chris Mullin used to go to his laboratory 35 miles away from his house, the sunrays directly hit his eyes. The high penetrating rays cause headaches and give him trouble to see properly. Thus he decided to make a sunglass that may block the sun rays and protect his eyes. In 2002 he got a chance to work on his idea.
As lens material, he used a liquid crystal. The liquid crystal doesnâ??t give any obstruction to see through as a sunglass lens. Then he added a sensor on the bridge of the nose which finds limelight and gives a signal to a microcontroller attached nearby.
The microcontroller reacts and gives instruction to the liquid-crystal lens to produce a 6 mm black square in front of the eyes to block the limelight. Surprisingly the square moves with the glass wearer to block the source of limelight at all the angles, but still gives a gap on the surroundings to let see properly.
Mullin is now developing an elastically plastic-based LCD, so that the product may be lighter and damage proof to sell in the market on a commercial scale.
The U.S Air Force has appreciated Mullin work and has funded his project. Now he is working on developing a sunglass for soldiers & fighter pilots. Mullin claims that troops may go in high-noon sun onto the other place without any harm in illumination.
The sight of the sunglass wearer will not be damaged. They may be able to see at the very moment after walking into the sun. The scientist doctor makes a plan to sell the idea to any of the big manufacturers of sunglasses, so that they produce this Dynamic Eye shades commercially.
