Open the CIPO recordAbstract From the Canadian patent
Control systems and methods are disclosed for processing a time series of signals associated with the movement of a device associated with a limb. The time series of motion signals is filtered such as thorough an autoregressive filter and compared to stored data sets representing a limb-motion event and/or phase. In certain examples a plurality of accelerometers generate the time series of motion signals based at least on acceleration measurements in three orthogonal directions and/or planes. The acceleration measurements may relate to the movement of an artificial limb such as a prosthetic or orthotic device. Upon determining an event and/or phase of limb motion the control system may …
