Renzo DeMeo 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 methods for making spectroscopic measurements of cathode fall in fluorescent lamps
    Publication number: 20060279221
    Abstract: Apparatus and methods are disclosed for measuring cathode fall within a fluorescent lamp that contains an electrode and a gas. A level of cathode fall associated with the electrode may be identified based on an intensity and wavelength of radiation emitted by the gas.
    Type: Application
    Filed: August 21, 2006
    Publication date: December 14, 2006
    Inventors: John Waymouth, Robert Nachtrieb, Farheen Khan, Mark Hartfield, Mark Taipale, Renzo DeMeo, Russell MacAdam

  • Apparatus and methods for making capacitive measurements of cathode fall in fluorescent lamps
    Publication number: 20060122795
    Abstract: Apparatus and methods for measuring cathode fall in fluorescent lamps are disclosed. Together with measurements of cathode temperature, such measurements of cathode fall may inform a determination of cathode heater voltage as a function of discharge current (i.e., a cathode-heating-profile) that avoids both sputtering and excess-evaporation.
