Title: Bihai Yuan and Cash-Note Anti-Counterfeiting Technology.

Introduction

Bihai Yuan is an inventor associated with Guangdong, China, and GRG Banking Equipment Co., Ltd. His work includes a patent focused on improving the collection of magnetic anti-counterfeiting information from cash notes.

Latest Patents

Yuan is named on one patent, Sampling Method and Sampling Apparatus for Anti-Counterfeiting Information About Cash Note. The invention describes a method and apparatus that use differences between sensor readings to reconstruct the spatially coupled power-frequency component of low-frequency electromagnetic interference. The method then applies common-mode signal elimination to voltage waveform data corresponding to the anti-counterfeiting information. This approach is intended to reduce power-frequency and low-frequency electromagnetic interference affecting magnetic sensors during signal collection. Yuan’s listed patent portfolio includes 1 patent.
