Title: Wei Liang Keith Nguyen and Optical Noise Reduction in Sensor Systems.

Introduction

Wei Liang Keith Nguyen is an inventor associated with Singapore. His patent work addresses optical noise reduction in ranging, proximity, and image sensors, with an approach designed to improve the reliability of optical measurements.

Latest Patents

Nguyen is associated with 1 patent: “Retroreflective Mechanisms on Optical Ranging, Proximity, and Image Sensors to Reduce Optical Noise from Unwanted Sources.” The invention describes an electronic sensor system with a housing cap that has separate transmission and receiving openings. An optical source sends ranging radiation through the transmission opening toward a target, while a receiver detects radiation reflected from that target through the receiving opening. A retroreflective mechanism on the housing cap redirects unwanted optical noise toward its source and away from the receiver. The system can then determine properties of the target from the received ranging radiation.

Career Highlights

Nguyen is associated with STMicroelectronics International N.V. His patent reflects work on sensor design and the management of unwanted light, which can interfere with optical ranging and proximity measurements.

Collaborations

Nguyen’s listed coworker is Jelah Nieva Caceres. The patent’s technical approach combines optical transmission, reception, and retroreflection to help distinguish useful signals from unwanted optical noise.

Conclusion

Wei Liang Keith Nguyen’s patent focuses on reducing optical interference in sensor systems by redirecting unwanted light away from the receiver, supporting more dependable measurements of target properties.
