Dong TU 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).

  • Mechanoluminescent material, coating containing mechanoluminescent material, mechanoluminescent substance and method for producing mechanoluminescent material
    Patent number: 11225603
    Abstract: The purpose of the present invention is to provide a mechanoluminescent material which can be exhibit brighter luminescence compared to traditional SAO mechanoluminescent material even with respect to small strains and which has a relatively high mechanoluminescent capability even when left to stand for a long period of time after excitation. Provided is a strontium aluminate mechanoluminescent material containing Zr ions, characterized in that the Zr ions are contained in a reduced state, the content of the Zr ions is 10 mol % or less, and in a thermoluminescence measurement, one or more luminescence peaks are observed at a temperature of 100° C. or higher.

  • Pattern based audio searching method and system
    Patent number: 10671666
    Abstract: A pattern based audio searching method includes labeling a plurality of source audio data based on patterns to obtain audio label sequences of the source audio data; obtaining, with a processing device, an audio label sequence of target audio data; determining matching degree between the target audio data and the source audio data according to a predetermined matching rule based on the audio label sequence of the target audio data and the audio label sequences of the source audio data; and outputting source audio data having matching degree higher than a predetermined matching threshold as a search result.
