The only time we use Bluetooth is to yap about in our cars while we’re driving or for transferring photos to and from our computer, but Marine Lance Cpl. Joshua Bleill is using it to help him walk again. The Iraq veteran has dual prosthesis with Bluetooth transmitters on board that sends signals between each motor, which updates each piece of the legs on what the others are doing, how it’s moving, and whether or not they need to make adjustments.
Older models of computer-controlled legs have to be “programmed” via wire by laptop computers before the amputee can use them. Those legs required more movement from the amputee’s remaining thigh muscle to generate motion in the prosthetic leg.
Because of built-in motors, the Bluetooth legs allow Bleill to walk longer before he tires.
“We’ve compared walking several laps in both sets of legs and one, your legs come out burning and tired and these, you know, you sometimes are not even breaking a sweat yet.”
We weren’t kidding when we said it helps him kick ass. “So sometimes the leg kicks harder than I want it to, or farther, and then I start perpetuating, and I start moving faster than I really want to.” [CNN]
