Abstract
Systems, devices and methods for detecting ground contact with a lower-limb POD. A sensor array for the POD on a first or second body may include two or more sensors in an array that each detect a distance to a respective target on the other of the first or second body. The first and second bodies may move relative to each other thereby changing an offset distance or distances between the two bodies which is detected by the sensors. In some embodiments, the sensors may include Hall Effect sensors that detect distances to respective magnets. Load data based on the detected distances may be generated for control of the POD, such as for stance phase control.
