Title: **Innovator Spotlight: Chaw-Wu Tseng**
Introduction
Chaw-Wu Tseng is a noteworthy inventor based in San Jose, California. He has made significant contributions to the field of engineering with a total of five patents to his name. His innovations primarily focus on the technology surrounding hard disk drives and their performance characteristics.
Latest Patents
One of Chaw-Wu Tseng's latest inventions is the "Head Stack Latch Assembly." This patent discloses a Load-Unload (LUL) hard disk drive that includes a disk base equipped with a spindle motor. This motor rotates disks to create at least one active disk surface. The head stack assembly, pivotably coupled to the disk base, engages an actuator latch designed for parking the sliders safely. The actuator latch incorporates a latch beam connected through a pivot to the disk base, and a boss that limits the stroke of latch motion in response to rotary non-operational shock.
Another significant patent is his "Method for Predicting Vibrational Characteristics of Rotating Structures." This method involves analyzing the vibrational features of rotating devices like hard disk drives and jet engines, which are attached to flexible supports via bearings. The approach entails discretizing both the rotating device and the support, calculating natural frequencies of their elastic vibration modes, and employing modal analysis to predict the vibrational response accurately. This analytical method is vital for designing devices with optimized vibrational characteristics.
