Latest Patents

Mickleson's latest patents include innovative systems designed to enhance the performance of information detection devices. One of his key inventions is the "Dithered Focusing System," which is a servo control system that maintains an information detection device, such as a light beam, at the optimum focused position above an information track. This system retrieves the maximum amount of reflected radiation from an information track, such as a spiral recording track on a videodisc. The invention features an optical system, a piezoelectric dither element, a dither oscillator, and circuitry for deriving an intermediate signal indicative of the dither's effect on the detected signal. Additionally, it includes phase comparison circuitry for generating an error signal and a movable lens assembly that accurately focuses the light beam on the information track.

Another significant patent is the "Dithered Center Tracking System," which also serves as a servo control system. This system is designed to keep an information detection device, like a light beam, centered on a moving information track. Similar to his previous invention, it incorporates an optical system, a piezoelectric dither element, and circuitry for deriving an intermediate signal. The phase comparison circuitry in this system generates a known error signal, ensuring precise tracking of the light beam on the information track.
