Yeong Jun 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: 11815520
    Abstract: This application relates to a movable apparatus for collecting and analyzing specimens. In one aspect, the movable apparatus includes a transport means configured to be moved independently and to maintain negative pressure therein by a negative pressure module, and a specimen collecting device arranged in the transport means and configured to collect a specimen under remote control by inserting a specimen collecting member into the nasal cavity of a testee who enters the transport means. The apparatus may also include a specimen transport device arranged in the transport means and configured to transport the specimen collecting member under remote control that has collected the specimen in one direction, and a specimen analysis device arranged in the transport means and configured to extract the specimen from the specimen collecting member that has been transported by the specimen transport device under remote control and to analyze the specimen.
