His innovative work has the potential to impact various industries, particularly in the realm of assistive technologies.
Latest Patents
Among his latest patents, Leonard has developed a drive mechanism designed for driving one or a plurality of displaceable elements around a closed path, such as a circle. This mechanism utilizes a linear induction actuator, which is associated with means for constraining the displaceable elements to move in the closed path. A capacitive feedback control system is employed to determine the position of the elements around the path and to control the windings of the linear induction actuator based on an error signal generated from this system. Additionally, his invention encompasses an open path drive mechanism featuring multiple linear induction actuators and a capacitive feedback control system. Leonard's work also includes hybrid linear induction motors that utilize sets of arcuate linear induction actuators around the rim of a reaction member, which drives an output shaft of the motor.
