Title: **Innovative Contributions of Howard W. Johnson**
Introduction
Howard W. Johnson, an accomplished inventor based in Sunnyvale, CA, is recognized for his impactful advancements in data transmission technologies. With a portfolio of 12 patents, he has made significant contributions to the field, particularly in encoding and decoding methods for digital data transmission.
Latest Patents
Among Johnson's latest patents is the "Encoding/detection method for digital data transmitter with a signal." This invention introduces an innovative approach to encoding a signal that encompasses at least two different positive and negative levels. Each symbol, representing two binary bits, is encoded within a symbol period. This method ensures that during each symbol period, the encoded signal transitions between levels of opposite polarity, eliminating any DC component and shifting the frequency spectrum away from lower frequencies.
Another noteworthy patent is the "Method and apparatus for synchronized transmission of data between a." This patent details a process whereby binary data is transmitted to a network physical layer from a media access controller as a series of multibit nibbles. The data is encoded into a multi-level data stream and distributed among several transmission channels, effectively reducing the signal frequency necessary to transmit the data. At the receiver end, this multi-level signal is translated back into a binary data stream, with transmission frequencies synchronized with the nibble transfer rate.
Career Highlights
Throughout his career, Howard W. Johnson has contributed his expertise to renowned companies such as Echelon Corporation and 3Com Corporation. His work in these organizations has played a pivotal role in the development of innovative technologies in data transmission.
