Patents by Inventor John Kropf

John Kropf 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).

  • Publication number: 20090249973
    Abstract: A networked guideway transit system uses permanent magnet repulsion with induction-based repulsion within the networked guideway transport system, which can levitate passively with motion. Magnetic levitation technology is used to replace wheels as the primary means of vehicle suspension. The networked guideway transit system uses the permanent magnets to provide primary lift and uses electrodynamic repulsion to create centering forces at most operational speeds while integrating linear motor functions with the electrodynamic centering function. Further, the networked guideway transit system uses no moving parts in the guideways, which enhances reliability in the guideways.
