Title: The Innovative Mind of Chi-Hung Wu
Introduction
Chi-Hung Wu, an accomplished inventor based in Hsinchu, Taiwan, is known for his significant contributions to the field of light-emitting devices and sampling rate determination methods. With two notable patents to his name, Wu continues to push the boundaries of innovation in technology.
Latest Patents
Chi-Hung Wu has recently developed two groundbreaking patents. The first, titled "Light-emitting device manufacturing method," outlines a novel approach to manufacturing light-emitting devices. This method includes steps for providing an as-cut wafer that features an irregularly uneven surface with surface roughness greater than 0.5 micrometers. The subsequent formation of a light-emitting stack on this uneven surface is achieved through an epitaxial growth method, resulting in a stack with an upper surface roughness of less than 0.2 nanometers. This innovative approach eliminates the need for any patterning or roughing process between the initial wafer preparation and the light-emitting stack formation.
The second patent focuses on a "Method for determining sampling rate and device therefor." This invention provides a comprehensive method for determining sampling rates by analyzing input signals, specifically SPDIF. It involves obtaining multiple values based on bi-phase clock frequencies of the input signal and system frequency, allowing for the calculation of weighted averages. By assessing differences between these averages, the method provides a rapid determination of the sampling rate, reducing the risk of errors and conserving memory.
