Evan Stuart Johnston 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).

  • Respiratory air temperature and pressure sensor
    Patent number: 8147420
    Abstract: An apparatus and method can be configured to detect respiratory air temperature information and respiratory air pressure information from a patient using a first piezoelectric film and a second piezoelectric film, wherein at least a portion of the second piezoelectric film overlaps at least a portion of the first piezoelectric film. In an example, the first and second piezoelectric films can be sized and shaped to be disposed on an upper lip of a subject. In certain examples, the first piezoelectric film can include a non-overlap portion exposed to nasal respiration, and the second piezoelectric film can include a non-overlap portion exposed to oral respiration.
    Type: Grant
