Introduction

Richard J Futch is a notable inventor based in Lawrenceville, GA (US), recognized for his contributions to technology with a total of 9 patents. His work primarily focuses on advancements in network architecture and data transmission.

Latest Patents

One of his latest patents is titled "Clock synchronization in a bidirectional network." This invention presents an architecture that provides high-speed access over frequency-division multiplexed (FDM) channels, allowing the transmission of Ethernet frames and other data across a cable transmission network. The architecture employs downstream and upstream FDM multiplexing techniques to facilitate contemporaneous, parallel communications across multiple frequency channels. It also supports a central concentrator that manages several remote devices, ensuring guaranteed bandwidth through connection-oriented allocations of bi-directional data flows. This architecture can accommodate both symmetrical and asymmetrical bandwidth allocation in either direction, thereby enhancing local network performance.

Another significant patent by Futch is "Transporting upstream data in a passive optical network." This invention addresses upstream data handling in a digital Data Over Cable Service Interface Specification (DOCSIS) passive optical network (DPON). The process involves receiving digitized and serialized DPON upstream packets in a time division multiplexed manner. It includes monitoring the optical network for energy in the upstream path and controlling a bit stuffer to manage the addition of bits based on detected energy. The original payload is then converted from digital to analog and passed to a cable modem termination system (CMTS).
