Latest Patents
One of Kevin's latest patents is the "Multichannel biphasic signal generator circuit." This circuit includes first and second current control sub-circuits connected in series between a DC supply voltage node and a reference voltage node. Additionally, it features third and fourth current control sub-circuits also connected in series between the same nodes. The circuit incorporates a DC/DC converter with input terminals coupled to load nodes between the current control sub-circuits. It further includes output electrodes, a routing sub-circuit for selectively coupling the output electrodes to the output terminals, and a controller designed to operate the routing sub-circuit and current control sub-circuits to supply biphasic pulses.
Another significant patent is for "Systems and methods for volitional control of jointed mechanical device based on surface electromyography." This system is designed to control a weight-bearing member with at least one powered joint. It includes a velocity reference module that receives myoelectric control signals from a user during a non-weight-bearing mode and generates a velocity reference for the powered joint. The system also features a volitional impedance module that generates a torque control signal for actuating the powered joint based on the velocity reference.
