Introduction

Hua Liu is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of touch sensing technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and reliability of touch sensing systems.

Latest Patents

One of his latest patents is a touch sensing system that includes a detected capacitor Cm. This system features a transmitting electrode and a receiving electrode arranged at two ends of the detected capacitor Cm. The receiving electrode is connected to a modulation module via a GM module. An excitation signal is input from the transmitting electrode, while the GM module converts the charge transferred to the receiving electrode into a current. This current is then output to the modulation module, which performs integration and modulation to obtain an output parameter characterizing the detected capacitor Cm. This innovation aims to reduce chip area and power consumption while improving the reliability of touch sensing.

Another notable patent is for body position sensing equipment. This device includes a receiving surface designed for positioning at least one human body part. It features multiple capacitive sensor elements within various positioning areas on the receiving surface. A sense circuit compares the capacitance measurements of the sensor elements with threshold capacitance values, generating a signal when proximity of a human body part is detected. An indicator then generates a notification when the position of the human body part corresponds with a location on the receiving surface.
