Title: Innovations by Yun-Fan Chang

Introduction

Yun-Fan Chang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of sound technology, holding two patents that showcase his innovative approach to sound localization and physiological sound recognition.

Latest Patents

Chang's latest patents include a "Multi-mic sound collector and system and method for sound localization." This invention features a sound localization system that comprises a multi-mic sound collector and a computing device. The multi-mic sound collector consists of a carrier and multiple sound receivers that can be attached and removed. The computing device is equipped with a data communicator, a synchronizer, and a processor. The data communicator receives preprocessed audio data from the sound collector, while the synchronizer ensures that the audio data is synchronized. The processor then analyzes this data to identify and localize target audio features. This invention is particularly beneficial for monitoring physiological signs and allows for early detection and diagnosis of abnormalities or diseases.

Another significant patent by Chang is the "Method and system for recognizing physiological sound." This system includes a receiving module, a feature extracting module, a classifier, and a comparing module. The method involves receiving a physiological sound, extracting features from it, classifying these features, and comparing them with normal or abnormal physiological sounds to evaluate disease risk. This innovation enables precise identification of specific physiological sounds while filtering out noise.
