Title: Thomas Hong Chuang: Innovator in Vibration Measurement and Dynamic Balance Correction

Introduction

Thomas Hong Chuang is a notable inventor based in Oklahoma City, OK (US). He holds a total of 8 patents that showcase his contributions to the fields of vibration measurement and dynamic balance correction. His innovative work has significantly impacted various industries, particularly in the manufacturing of disc drives.

Latest Patents

One of his latest patents is a "Vibration measurement apparatus and method." This invention involves an apparatus designed to measure vibration in an article that has a rotating member. A motion-sensitive transducer produces a time domain analog signal in response to the vibration. An analog-to-digital data acquisition member samples the transducer signal and produces a time domain digital signal. A timing sensor detects the instantaneous speed of the rotating member and triggers the data acquisition member to begin sampling when the rotating member is in motion. A processor processes the time domain digital signal, translating it into a frequency domain digital signal and determining the magnitude and phase of the frequency domain digital signal at a frequency associated with the instantaneous speed of the rotating member.

Another significant patent is for "Dynamic balance correction for a disc drive." This method balances a rotary object, such as a disc drive disc pack. A balance correction member is provided as a C-shaped ring formed from a length of wire with a nominally uniform cross-sectional area. The member has a substantially elliptical shape in an uncompressed state. During installation, the amount of imbalance in the disc pack is measured, and a member with an appropriate length is selected and compressed to a substantially circular shape. The compressed member is then placed adjacent to the disc pack, allowing it to expand and compressingly engage an annular recess in the disc pack. This member is preferably installed using an automated dynamic balance correction station as part of a high-volume disc drive manufacturing environment.
