Patents by Inventor Kenneth C. Syracuse

Kenneth C. Syracuse 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).

  • Lithium/carbon monofluoride (Li/CF) electrochemical cell projection model
    Patent number: 7068036
    Abstract: A model for estimating the discharge profile of a Li/CFx cell is described. The model uses as inputs the load at which the cell is subjected to and the planar surface area to estimate current density. Then, current density is used to estimate cell voltage at each 2% depth-of-discharge.
    Type: Grant

    Inventors: Kenneth C. Syracuse, Esther S. Takeuchi
  • Fuel gauge for an alkali metal electrochemical cell
    Patent number: 6377850
    Abstract: A “fuel gauge” for a pulse dischargeable alkali metal/solid cathode cell is described. The rate of voltage recovery is used to determine the state of charge of the cell. Voltage recovery includes recovery from one load to a second, lighter load, or a loaded condition to OCV. The present invention is particularly useful as an end-of-life indicator for a Li/CFx cell powering an implantable medical device.

  • Alternate fuel gauge for an alkali metal electrochemical cell
    Patent number: 6166524
    Abstract: A "fuel gauge" for a pulse dischargeable alkali metal/solid cathode cell is described. The rate of voltage recovery is used to determine the state of charge of the cell. Voltage recovery includes recovery from one load to a second, lighter load, or a loaded condition to OCV. The present invention is particularly useful as an end-of-life indicator for a Li/CF.sub.x cell powering an implantable medical device.
