Kuan Choong Shim

Title: Kuan Choong Shim: Encoder and Code-Wheel Inventor.

Introduction

Kuan Choong Shim is an inventor based in Penang, Malaysia. His work includes a patented code-wheel design intended to improve index signals and index-gating margins. Shim is associated with PixArt Imaging Inc.

Latest Patents

Shim is named on one patent, titled “Code Wheel and Encoding System Which Can Improve Index Signal and Index Gating Margin.” The invention describes a code wheel with a signal region that receives light and generates code signals, and an index region that generates a signal representing a complete rotation. The index region includes two regions of different sizes, with the smaller region closer to the signal region. In an encoding system, a processing circuit uses the code and index signals to determine the code wheel’s rotation.

Career Highlights

Shim’s patent work focuses on optical encoding, where light-based signals help determine rotational position. The design’s index-region arrangement is intended to improve the reliability of the index signal and the margin for index gating.

Collaborations

Shim’s listed coworkers include Tze Wei Priscilla Goh and Meng Yee Lim. His association with PixArt Imaging Inc. places his work within a company known for imaging and sensing technologies.

Conclusion

Kuan Choong Shim’s documented contribution is a patented optical encoder design that addresses index-signal generation and rotation detection.
