Patents by Inventor Edward R. Kolbe

Edward R. Kolbe 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).

  • Variable frequency automated capacitive radio frequency (RF) dielectric heating system
    Patent number: 6784405
    Abstract: A food product is heated by maintaining the food product in an AC electrical field generated by an RF signal. As the heating takes place, maximum energy is delivered to the food product using automatic impedance matching to adjust the rate of the process.
    Type: Grant
    Filed: April 24, 2003
    Date of Patent: August 31, 2004
    Assignees: The State of Oregon, acting by and through the State Board of Higher Education on Behalf of Oregon State University
    Inventors: Benjamin A. Flugstad, Qingyue Ling, Edward R. Kolbe, John Henry Wells, Yanyun Zhao, Jae W. Park

  • Capacative dielectric heating system
    Patent number: 6303166
    Abstract: A food product is heated by maintaining the food product in an AC electrical field provided by an RF signal at an RF frequency that matches a Debye resonance frequency or frequencies of one or more components of the food product. As the food product warms, the frequency of the RF signal is automatically adjusted to track changes in the Debye resonance frequency, which shifts in frequency as the temperature rises. Individual regions of the food product can be heated, by the use of grid electrodes, at different rates to assure uniform warming or to achieve a particular desired warming pattern.
