Abstract From the Canadian patent

A robotic exoskeleton (101, 102, 103, 104) and a control system (115) for driving the robotic exoskeleton, including a method for making and using the robotic exoskeleton and its control system (115). The robotic exoskeleton has sensors (111, 112, 113, 114) embedded in it which provide feedback to the control system. Feedback is used from the motion of the legs themselves as , they deviate from a normal gait, to provide corrective pressure and guidance. The position versus time is sensed and compared to a normal gait profile. Various normal profiles are obtained based on studies of the population for age, weight, height and other variables.

Why it's free to use

  • Filed August 21, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 21, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 21, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
