Title: Patrick K. Kelly: Inventor in Full-Duplex Communication Systems
Introduction
Patrick K. Kelly is an inventor associated with Toney, Alabama, and Motorola Corporation. His patent work addresses speakerphone technology and the control of full-duplex communication systems.
Latest Patents
Kelly is credited with 1 patent: “Method and Apparatus for Controlling a Full-Duplex Communication System.” The invention uses automatic gain control (AGC) in talk mode and applies the inverse of the gain factor to the received signal, helping avoid the need to adapt acoustic echo-canceller coefficients as volume changes. It also adjusts energy thresholds to distinguish talk, double-talk, and listen modes, and varies loop gain to help maintain system stability.
Career Highlights
Kelly’s listed patent reflects work on managing audio levels, echo cancellation, and stability in speakerphone systems. The available information associates his work with Motorola Corporation.
Collaborations
John E. Lane and Robert Victor Holland are identified as Kelly’s coworkers.
Conclusion
Patrick K. Kelly’s patent describes techniques for improving gain control, mode detection, and loop stability in full-duplex speakerphone communication systems.
