Engineers develop computerized bionic leg to help amputees walk faster, easier and with better balance

For a brief time, Kerry Finn felt like "The Terminator" or "The Six Million Dollar Man." The 60-year-old retired truck driver from Salt Lake County, Utah, lost his left leg to vascular disease from type 2 diabetes. But last year, he was one of 10 human subjects at the University of Utah to test one of the world's first truly bionic legs, a self-powered prosthetic limb with a computer processor and motorized joints in the ankle and knee that enable an amputee to walk with more power, vigor and better balance.
