Patents by Inventor Gary Van Stephenson

Gary Van Stephenson 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).

  • Patent number: 10957473
    Abstract: A superconducting magnetic energy storage system (SMES). The SMES includes a toroidally wound super conducting magnet having a toroidal magnetic core with a charging winding and a discharging winding. The charging winding and discharging winding are wound on the toroidal magnetic core. The SMES also includes a DC power source, the DC power source operable to provide DC current to the charging winding of the toroidally wound superconducting magnet, and a modulator operably connected to the DC power source and the charging winding, the modulator operable to modulate at least a portion of the DC current applied to the charging winding of the superconducting magnet. The energy is stored in a magnetic field of the superconducting magnet by applying a current to the charging winding of the superconducting magnet, and energy is withdrawn from the magnetic field by a current flowing in the discharging winding.

  • Patent number: 10660785
    Abstract: A garment for long duration waste removal includes, among other things, a containment layer, a containment interface defining a passage, a storage container extending from the containment interface, and a cleansing member routed through the passage, and into the storage container. The cleansing member is moveable relative to the containment layer to remove solid waste. A waste management system for long duration vehicle operations is also disclosed.
