Patents by Inventor Yun-Fan CHANG

Yun-Fan CHANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10159459
    Abstract: A sound localization system includes a multi-mic sound collector and a computing device. The multi-mic sound collector includes a carrier and a plurality of sound receivers removably attached to the sound receivers. The computing device includes a data communicator, a synchronizer, and a processor. The data communicator receives preprocessed audio data from the multi-mic sound collector. The synchronizer synchronizes the preprocessed audio data. The processor analyzes the synchronized audio data to identify and localize a target audio feature. A sound localization method of the sound localization system is also provided. The present invention facilitates monitoring of the functioning or physiological signs of a monitored subject and allows early detection and diagnosis of abnormalities or diseases.

  • Patent number: 9687208
    Abstract: A system for recognizing physiological sound comprises a receiving module, a feature extracting module, a classifier, and a comparing module. A method for recognizing physiological sound comprises receiving a physiological sound by the receiving module; extracting at least one feature from the physiological sound by the feature extraction module; classifying the at least one feature to identify at least one category by a classifier; and comparing the at least one category with a normal physiological sound and/or an abnormal physiological sound by the comparing module for evaluating a risk of disease. The method and system for recognizing physiological sound can precisely identify the specific physiological sound and exclude the noise.
