Title: Innovations of Inventor Chen-Yi Chang
Introduction
Chen-Yi Chang is a notable inventor based in Taichung, Taiwan. He has made significant contributions to the field of technology, particularly in yield analysis and energy-saving functionalities for small cells. With a total of 4 patents, his work reflects a commitment to advancing technological solutions.
Latest Patents
One of Chen-Yi Chang's latest patents focuses on generating root cause candidates for yield analysis. This invention relates to techniques for yield analysis that identify points of interest in a layout design. Regions of interest are then determined for these points, and properties are extracted to analyze diagnosis reports of failing devices. This process aids in identifying probable root causes of failures.
Another significant patent addresses energy-saving functionality for small cells in E-UTRA and E-UTRAN. This invention provides an apparatus and method for small cell energy saving. It includes a novel aspect where a switch-off-request is broadcasted by the small cell when a low-load condition is detected. The small cells enter a frozen state upon receiving this request, preventing them from switching off. Additionally, the small cell requests measurement reports from user equipment (UEs) to gather information about neighboring IDs and traffic load, which is then included in the switch-off-request message.
