Abstract
A prosthetic or orthotic system including a magnetorheological (MR) damper. The MR damper may be configured to operate in shear mode. In one embodiment, the MR damper includes a rotary MR damper. A controller is configured to operate the damper. A mobile computing device may be adapted to intermittently communicate configuration parameters to the controller. A method of configuring a prosthetic or orthotic system is also disclosed.
Claims12
A method of controlling a prosthetic having a movement damper, comprising:
- measuring at least one characteristic of prosthetic movement;
- calculating a damping value based at least partly on the at least one characteristic;
- applying a filter, wherein the filter receives a calculated current, to filter the damping value based at least partly on input of values of previous damping values to the filter;
- and
- applying the damping value to control resistance of a damper.
