New AKA Robotic Prosthetic

So, there's the C-Leg and now another company is coming out with a robotic knee for AKAs (above knee amputees).
Enter the Rheo Knee. Supposedly it measures the speed and force that the walker uses and then adjusts the knee swing in milliseconds. From ScienCentral:

...built-in sensors that can measure how far the knee is bent, as well as the amount of force the user applies to it while walking – a computer chip then analyses user's walk and continually adapts the movement and resistance of the knee accordingly.

I really didn't read any differences with the C-Leg, except that this knee uses magnetorheological fluid instead of oil in the knee joint. But maybe it'll create some competition and the price will go down. Who knows.
