Title: Guanhua Cao: Innovator in Noise Suppression and Object Classification

Introduction

Guanhua Cao is a prominent inventor based in Shanghai, China. He has made significant contributions to the fields of noise suppression and object classification through his innovative patents. With a total of 2 patents, Cao continues to push the boundaries of technology.

Latest Patents

Cao's latest patents include a system for short-term noise suppression. This processing system is designed to drive a transmitter electrode with a repetitive multi-burst pattern. The pattern consists of a first multitude of bursts of a sensing waveform and a second multitude that repeats the first. The system is capable of receiving a resulting signal from a receiver electrode and identifying segments least affected by noise. This identification coincides with bursts in the first and second multitude of bursts. Additionally, the system decodes the resulting signal using the identified segment.

Another notable patent focuses on object classification under low-power scan conditions. This method involves performing a first low-power scan to detect an input object in a sensing region. It determines whether the object is of interest and, if so, performs a high-power scan. If the object is deemed of no interest, a second low-power scan is conducted.
