Title: Weiguo Zhao and Ultrasound Echo Measurement

Introduction

Weiguo Zhao is an inventor associated with China Jiliang University in Hangzhou, China. His patent work addresses the measurement of ultrasound echo signals, with a focus on improving the accuracy of time-of-flight calculations.

Latest Patents

Zhao is associated with 1 patent: “Methods for Measuring Times-of-Flight of Ultrasound Echo Signals.” The invention describes capturing an ultrasound echo signal, then denoising and reconstructing it using an empirical wavelet transform. It uses reconstructed and reference echo peak values, along with a characteristic-peak positioning algorithm, to identify an echo characteristic point. A measurement algorithm then determines the signal’s time-of-flight from that point. The disclosed approach aims to improve measurement accuracy through relatively simple calculations.

Career Highlights

Zhao’s listed patent reflects work in measurement technology and signal processing. It applies signal reconstruction and peak identification to a practical challenge in ultrasound time-of-flight measurement.
