Latest Patents

Chih Long Dai holds a patent for a "Long seek control system and method in an optical storage device." This patent includes a reference velocity mapping unit that obtains a reference velocity when the dual actuator is moved by the residual track count. It features a velocity estimator that outputs an estimated velocity and obtains a sled control effort by subtracting the estimated velocity from the reference velocity. Additionally, an electrical damper receives the sled control effort and the displacement of the dual actuator to output a damping control effort to the fine actuator, thereby reducing the vibration of the fine actuator during long seek operations. The reference velocity mapping unit utilizes a reference velocity curve to describe the mapping relation between the residual track count and the reference velocity, which includes a linear part and several quadratic parts with different quadratic functions. Chih Long Dai has 1 patent to his name.
