Latest Patents

One of his latest patents is titled "Positional control method and system utilizing same." This invention features a control system and method that includes an integrator coupled with a rate-varying multiplier, operating in parallel with a conventional controller. The integration is rate-variable, which allows the control system to benefit from integral position control while avoiding issues such as integral windup and overshoot. This system demonstrates reduced following and steady-state error, faster settling time, and improved noise tolerance compared to traditional PD and PID controls, particularly in the context of controlling robots. Additionally, the method significantly reduces errors caused by mechanical static friction, known as 'sticktion,' without compromising the system's dynamic performance.

Another notable patent is the "Method and system for automatically determining the position and attitude of a three-dimensional body at a work station." This invention utilizes three cameras that generate non-overlapping planes of image data, capturing a single target point of the body without structured light. The system processes the locations of these target points alongside calibration data to determine the position and attitude of the body relative to the work station. The resultant data is transformed into offset data for peripheral devices, such as robots and programmable controllers, allowing them to adjust their pre-programmed paths accordingly.
