Title: Michael E. Lewis: Innovator in Data Rate Shifting and Signal Processing
Introduction
Michael E. Lewis is a notable inventor based in Hartville, OH (US), recognized for his contributions to data communication technologies. With a total of 12 patents to his name, Lewis has made significant advancements in methods for data rate shifting and signal processing.
Latest Patents
Among his latest patents, Lewis has developed a technique for data rate shifting that determines when to change a data rate by analyzing the cause of packet loss. This innovative method distinguishes between collision-mediated packet loss and poor signal-mediated packet loss. By shifting to a lower data rate when poor signals are detected, the technique allows for a comparison of packet loss rates before and after the switch. If the packet loss rate does not improve, the data rate can be adjusted back to a higher rate. This method utilizes a combination of channel response, signal strength, packet loss rate, and throughput to optimize data rate switching.
Another significant patent involves a method and implementation for adaptive symbol decision mapping. This invention aims to reduce signal distortion by establishing decision boundaries for symbol detection. The symbol detector assigns symbols from a received signal to constellations separated by these boundaries. A quality measure implementation assesses the error rate of the symbol detector's output, allowing for adjustments to the decision boundary positions and shapes to minimize errors.
Career Highlights
Throughout his career, Michael E. Lewis has worked with prominent companies such as Cisco Technology, Inc. and Canadian Auto Preservation Inc. His experience in these organizations has contributed to his expertise in data communication and signal processing technologies.
