Sameer Hemmady 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).

  • Apparatus and method to distinguish nominally identical objects through wave fingerprints apparatus and method to distinguish nominally identical objects through wave fingerprints
    Patent number: 8624605
    Abstract: The present invention exploits extreme sensitivity to initial conditions in ray-chaotic enclosures to create a method to distinguish nominally identical objects through their unique “wave fingerprints.” The fingerprint can be measured through transmission of a pulsed microwave signal as a function of carrier frequency and time. When internal components are re-arranged, the Electromagnetic Fingerprints (EMF) changes in significant ways. The EMF can be detected by direct injection measurements of the enclosure or through remote measurement.
