Title: Michael C Fischer: Innovator in Electronic Device Technology

Introduction

Michael C Fischer is a prominent inventor based in Palo Alto, CA (US). He has made significant contributions to the field of electronic devices, holding a total of 16 patents. His work focuses on enhancing the performance and functionality of portable electronic devices.

Latest Patents

Among his latest patents are innovations such as a portable electronic device stand and methods for harmonic correction in phase-locked loops. The latter addresses the effects of harmonic disturbances in a phase-locked loop by employing harmonic correction techniques. This correction can be continuously present in the loop or activated once the loop achieves phase lock. Disturbances within the loop bandwidth are mitigated using additional integrating poles or resonant filters, while disturbances outside the bandwidth are corrected with low pass or notch filters. Additionally, a canceling signal may be generated to serve as a feedforward signal, utilizing a repetitive control scheme that employs filtered versions of residual errors from previous media rotations.
