Title: The Innovative Mind of Keng-Lon Lei
Introduction
Keng-Lon Lei, an accomplished inventor based in Taipei, Taiwan, has made significant contributions to the field of optical drive technology. With four patents to his name, Lei has developed innovative methods and devices that enhance the performance and stability of optical systems.
Latest Patents
Among his latest patents, the first is a "Method and device for adjusting a control parameter of a servo of an optical drive." This invention introduces a first sinusoidal signal into a control loop of the servo system while employing a band-pass filter to extract a second sinusoidal signal. By comparing the signal parameters of the two sinusoidal signals, Lei's technique identifies gain and phase variations within the control loop, allowing for adjustments that address system instability over prolonged use.
The second patent focuses on a "Method for controlling an optical pickup head upon switching from following mode to seeking mode." In this method, the first lead-lag compensator is disabled and a second is enabled when transitioning modes. The initial operating factor of the second compensator is determined based on previous input and output values, allowing the optical pickup head to actuate smoothly with calculated initial kick force during seeking operations.
