Title: Richard Brown and Redundant Controller Synchronization

Introduction

Richard Brown is an inventor based in Murrysville, Pennsylvania. His patent work addresses reliable operation in process control systems, particularly the synchronization of redundant controllers to support a smooth transition when a primary controller fails.

Latest Patents

Brown is associated with 1 patent: “Method for Redundant Controller Synchronization for Bump-less Failover During Normal and Program Mismatch Conditions.” The invention describes sending synchronization messages from a primary controller to a backup controller whenever a control area executes. These messages convey process-area state information needed to keep the controllers synchronized.

The patent also addresses failover when the controllers’ control areas do not match during reconfiguration downloads. In that situation, the backup controller can determine state information from other process-control network data and can be initialized at startup despite the mismatch. The approach is intended to support bump-less failover while maintaining process-control functions.

Career Highlights

Brown is associated with Emerson Process Management Power & Water Solutions, Inc. His patent reflects work on controller redundancy, synchronization, and continuity in process-control environments.

Collaborations

Conclusion

Richard Brown’s patent focuses on keeping redundant process controllers synchronized and enabling reliable failover, including when their configurations temporarily differ.
