Shang-Tai Yeh

Shang-Tai Yeh is a renowned inventor and patent holder from Taipei, Taiwan with a total of 100 patents. He is constantly pushing the boundaries of technology and his latest patents are definitely indicative of that.

His latest work consists of a stylus that is capable of transmitting electrical signals carrying pressure information, which is perfect for artists and graphic designers. This stylus comprises a first component with variable impedance reflecting a pressure, a second component with fixed impedance, and a conductive tip section that transmits electrical signals composed of the first and second signals simultaneously.

Furthermore, Yeh has also invented a touch-sensitive processing apparatus, system, and operating method thereof for receiving electrical signals carrying pressure information transmitted from a first stylus. This invention is groundbreaking, as through it, users can despread the electrical signals and calculate the pressure information based on a first signal strength ratio of a first part of the received electrical signal and a second part of the received electrical signal.

Yeh has worked with some of the biggest companies in the world, including EGALAX and EMPIA TECHNOLOGY INC., where he likely provided valuable insight and contributed to their engineering and manufacturing operations. Additionally, he has collaborated with some influential colleagues, such as Chin-Fu Chang and Shun-Lung Ho, who are also prominent figures in the technology industry.

Overall, Shang-Tai Yeh's contributions have made a significant impact in the field of stylus development and touch-sensitive processing apparatuses. It will be exciting to see what other innovative inventions he will come up with in the future.
