Sathya Motupally 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).

  • Electrochemical cells and systems
    Patent number: 7332238
    Abstract: An electrochemical cell or cell system includes an air mover, such as a fan, and one or more pressure-sensitive mechanisms, such as a slit valve, that allow air to enter or to exit the cell or system.
    Type: Grant
    Filed: September 6, 2002
    Date of Patent: February 19, 2008
    Assignee: The Gillette Company
    Inventors: Sathya Motupally, Jonathan O'Neill
  • Batteries and battery systems
    Publication number: 20060204835
    Abstract: A non-hermetically sealed, electrochemical power source, includes a first electrode, a second electrode, a separator between the first electrode and the second electrode, and a membrane in fluid communication with an environment external to the battery. The second electrode is between the separator and the membrane. The membrane includes a first portion having a different property, e.g., density, porosity, mass transport resistance, thickness, or gas permeability, than a second portion of the membrane. Methods of designing an electrochemical cell cartridge are also disclosed.
    Type: Application
