Double amputee walks again due to Bluetooth

Marine Lance Cpl. Joshua Bleill lost both his legs above the knees when a bomb exploded under his Humvee while on patrol in Iraq on October 15, 2006. He has 32 pins in his hip and a 6-inch screw holding his pelvis together. Now, he's starting to walk again with the help of prosthetic legs outfitted with Bluetooth technology more commonly associated with hands-free cell phones. "They're the latest and greatest," Bleill said, referring to his groundbreaking artificial legs.

Bleill, 30, is one of two Iraq war veterans, both double leg amputees, to use the Bluetooth prosthetics. Computer chips in each leg send signals to motors in the artificial joints so the knees and ankles move in a coordinated fashion. Bleill's set of prosthetics have Bluetooth receivers strapped to the ankle area. The Bluetooth device on each leg tells the other leg what it's doing, how it's moving, whether walking, standing or climbing steps, for example. "They mimic each other, so for stride length, for amount of force coming up, going uphill, downhill and such, they can vary speed and then to stop them again," Bleill told CNN from Walter Reed Army Medical Center, where he's undergoing rehab.

Unfortunately he will only have a walk time of about 6 hours but standby time of 3 days on one charge.
And he'll have to regenerate in his alcove at least once a day untill he can assimilate portable regeneration technology.

There is a company in Montreal that also makes a prosthetic leg for above the knee amputees. I don't think they're using BlueTooth, though. It also allows them to run and climb and down stairs stairs without any help.

They should have used short range flux for communication at each joint. Less chance for interference and getting your legs taken over by a cell phone. That or wires. Its great that the guy can walk again, but bluetooth? I smell marketing...
