The helmet used by the U.S. military has changed dramatically over the years.In World War I, the M1917/M1917A1 helmets,They were replaced in 1941 by the M-1 "steel pot," the standard-issue helmet in World War II, the Korean conflict and throughout the Vietnam War. By the 1980s, U.S. military helmets had evolved into a one-piece structure composed of multiple layers of Kevlar  29 ballistic fiber. The helmet of the near future, however, may contain something more than extra protection from flying shrapnel. An Arizona State University researcher, working under a grant from the U.S. Defense Advanced Research Projects Agency (DARPA), is trying to develop a military helmet equipped with technology to regulate soldiers' brains. The technology is transcranial pulsed ultrasound, which delivers high-frequency sound waves to specific regions of the brain. Under the influence of these sound waves, neurons send impulses to their targets, exerting control over them. On the ba

More than you'd think! In 1908 Henry Ford’s foreman, William Klann, visited a slaughterhouse seeing the ‘disassembly line’. He cleverly uses the same principles in reverse to create an ‘assembly’ line for the building of cars. The idea is to have the parts flow on a line to the workers who are stationary, rather than have the workers travel to each  station to complete the cars. Henry Ford's perfection of the assembly line in 1913, allows what used to take 12.5 man hours to be reduced to 1 hour and 33 minutes. This allows Ford to make cars faster and cheaper than ever before, producing vehicles that were affordable enough to make motor car travel a possibility for everyone, not just the wealthy.

Scientists are one step closer to completing robotic arms that are controlled by the brain. A device that would allow paralyzed people to use their thoughts to move robotic limbs fluidly and realistically is now one step closer to reality. A team of scientists from Harvard, MIT and Massachusetts General Hospital led by Ziv Williams have found two groups of cells in one area of the monkey brain th at allow the animals to remember a sequence of two movements at once. The team was then able to program a computer to interpret those brain patterns, in turn moving a cursor on a screen in the planned sequence. The development is an improvement over current brain-machine interfaces, which focus on translating a single thought into a single movement in an external device.
