Patents by Inventor John Bourg

John Bourg 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).

  • Pulsed low frequency EPR spectrometer and imager
    Patent number: 5502386
    Abstract: An EPR imager and spectrometer includes pulse generating system for generating broadband pulses having an RF carrier frequency that is not highly absorbed by biological samples. The pulse generating system includes up and down chirp convertors for frequency modulating a carrier frequency pulse and compressing the frequency modulated pulse to form a broadband excitation pulse of high energy. Such a machine could form the basis of a clinical imaging device capable of high sensitivity to free radical species in human patients.
    Type: Grant
    Filed: November 15, 1994
    Date of Patent: March 26, 1996
    Assignee: The United States of America as represented by the Department of Health and Human Services
    Inventors: John Bourg, James Mitchell, Mark Mirotznik, Bradley Roth, Sankaran Subramanian, Murali Cherukuri, Paul G. Zablocky, Thomas J. Pohida, Paul D. Smith, Walter S. Friauf, Rolf G. Tschudin
