A man who lost his hand 17 years ago has been given the sense of touch through a brain-controlled robotic prosthetic.Keven Walgamott, whose arm was amputated below the elbow after an accident, can now feel 119 different touch sensations through the prosthetic as if it were his own limb.He is able to distinguish between large, small, soft and hard objects when blindfolded, and handle delicate objects such as grapes and eggs. Everyday tasks such as putting on his wedding ring, peeling a banana or hol stanley tazas ding a mobile phone are no stanley cup w possible. The most amazing thing for me is what the team was able to do, said Walgamott. [They] take a bunch of mechanical pieces and provide, through a computer, not only the ability to move all fingers and grasp things but be able to feel again. The prosthetic hand and wrist has been in development for 15 years. Electrodes were implanted in the remaining part of his arm, allowing communication between the prosthetic hand and his brain. The hand can move in six directions and is equipped with 19 sensors that detect touch and positioning.The arrays interpret the signals Walgamotts brain sends to his arm nerves, and a computer outside the body translates these into digital information, which then instructs the prosthetic to move as the wearer intends.

Yet he walks free. As media reports have pointed out, body cameras devices may not help prosecute police officers 鈥?many episodes of apparent brutality are captured on camera, but charges against officers are infrequent. Still, some say the devices should not be dismissed. There are a lot of good reasons to think the technology could be a win-win, said Jay Stanley, a senior policy analyst at the American Civil Liberties Union. The organisation is known for its right-to-privacy advocacy, but Stanley comes down on the side of the cameras. He argues they could make police more accountable to the public, if the technology is done right . And that may be a big if, he said.Towns from Massachusetts to California have looked into purchasing the point-of-view cameras. Ypsilanti, Michigan, population 19,000, is buying the cameras.
