Dominique Lucienne Pfleger 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).

  • Controller for a continuously variable transmission
    Patent number: 6677685
    Abstract: A clamp pressure controller for a variable ratio belt drive system for a generator is provided. The controller monitors the voltage at the output of the generator. If this falls the controller increases the clamp pressure so as to prepare the drive system for the additional torque/force it will be required to transmit. The increase in clamp pressure is rapid so as to prevent belt slip from occurring.
    Type: Grant

  • Belt clamp force controller
    Publication number: 20020013188
    Abstract: A belt clamp force regulator is provided for controlling the clamp force exerted on a drive belt in a continuously variable transmission. The regulator seeks to maintain a clamp force greater than that required to transmit the mechanical load consistent with the output of the generator. This ensures that the belt will not slip. However, the controller reduces belt clamp when it can so as to improve the service life of the belt.
