Latest Patents

One of Bushey's latest patents is the "Linear actuator control structure." This control system is designed for a linear actuator that utilizes an electric motor drawing a variable current level during operation. The system includes a current level sensor that determines the operational current level of the actuator, along with a controller that generates a drive signal and a force request signal representative of the desired current level. The drive signal remains constant during a predetermined time interval, while a current limiting component minimizes the motor's current level based on a comparison between the force request signal and the desired current level.

Another significant patent is the "Back EMF actuator control." This control system estimates the approximate relative position of an electric linear actuator on a surface maintenance machine. It includes devices for selectively coupling the electric motor to the power source, measuring or estimating the current and voltage, and estimating the motor speed. The system integrates the motor speed over time to determine the approximate position of the linear actuator.
