Abstract: Systems and methods for controlling a weight bearing member having at least one powered joint are provided. A system includes a velocity reference module for receiving myoelectric control signals from a user during a non-weight bearing mode for the powered joint and generating a velocity reference for the powered joint based on the myoelectric control signals. The system further includes a volitional impedance module for generating a torque control signal for actuating the powered joint based at least on the velocity reference.

Abstract: A circuit includes first and second current control sub-circuits connected in series between a DC supply voltage node and a reference voltage node and third and fourth current control sub-circuits connected in series between the DC supply voltage node and the reference voltage node. The circuit also includes a DC/DC converter with a first input terminal coupled to the first load node between the first and second current control sub-circuits, a second input terminal coupled to a second load node between the third and fourth current control sub-circuits, a first output terminal, and a second output terminal. The circuit further includes output electrodes, a routing sub-circuit for selectively coupling the output electrodes to the output terminals, and a controller configured for operating the routing sub-circuit and the current control sub-circuits to cause the DC/DC converter to supply biphasic pulses for at least one of the pairs of output electrodes.
