Latest Patents

Phong Vu Nguyen Dao holds a patent for an invention titled "Adaptive removal of resonance-induced noise." This patent describes a method for removing noise from the digitized output of a sensor that is subject to undesired resonance. The invention is particularly valuable as it operates effectively even when the resonant frequency is unknown or drifts. The technology employs a very narrow notch filter that is recursive (IIR), ensuring low phase delay, which is crucial for applications in closed-loop control systems.

Career Highlights

Throughout his career, Phong Vu Nguyen Dao has demonstrated a commitment to advancing sensor technology. His work has led to the development of a tunable FIR filter that tracks the resonance intended for removal by the IIR filter. This innovative tuning process minimizes the output of the FIR filter, aligning the notch frequency with the resonant frequency. The adaptive tuning parameter is suitably scaled and biased, enhancing the effectiveness of the IIR filter.

Collaborations

Phong Vu Nguyen Dao has collaborated with esteemed colleagues, including Michael Alan Soderstrand and Stanley A White. Their combined expertise has contributed to the successful development and implementation of innovative noise reduction solutions.

Conclusion

In summary, Phong Vu Nguyen Dao is a pioneering inventor whose work in adaptive noise removal has the potential to significantly enhance sensor technology. His innovative approaches and collaborations reflect his dedication to improving the performance of closed-loop control systems.
