Stephen J. Lukasik 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).

  • Molecular separators, concentrators, and detectors preparatory to sensor operation, and methods of minimizing false positives in sensor operations
    Patent number: 8444921
    Abstract: As an elegant solution for minimizing false positives returned by a sensor tuned to an analyte molecule, filters constructed of carbon nanotubes are positioned relative to the sensor to limit the sensor to being exposed to molecules within a defined range of sizes, with too-big molecules being excluded from reaching the sensor by one filter, and too-small molecules being pumped out through another, finer filter before the sensor is operated.
    Type: Grant
    Filed: April 6, 2012
    Date of Patent: May 21, 2013
    Assignee: Advanced Concepts and Technologies International, L.L.C.
    Inventor: Stephen J. Lukasik
