Patents by Inventor David Edwin Kirtley

David Edwin Kirtley 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: 20230041682
    Abstract: Examples of advanced fuel cycles for fusion reactors are described. Examples include fuel cycles for use in field reverse configuration (FRC) plasma reactors. In some examples, reaction gases may be removed from a fusion reactor between pulses (e.g. plasmoid collisions). In some examples, a D-3He reaction is performed, with the 3He provided from decay of byproducts of previous reactions (e.g. tritium).

  • Patent number: 11442117
    Abstract: A system includes a control device and a magnetic device coupled to the control device. The magnetic device is configured to inductively couple to a treatment target including one or more cells exposed to an agent, and includes one or more magnetic coils. The control device and the magnetic device are collectively configured to generate and apply a transient magnetic field to the treatment target to induce an electric field and porate the one or more cells and to permit the agent to enter the one or more cells.

  • Patent number: 10760552
    Abstract: Systems and methods establish plasma in a rotating magnetic field. An exemplary embodiment is a plasma thruster that establishes a first transverse magnetic field with respect to a system axis of a plasma propulsion system; establishes a second transverse magnetic field oriented orthogonally to the first transverse magnetic field, wherein the second transverse magnetic field is out of phase with the first transverse magnetic field; and establishes a magnetic field aligned with the system axis using a plurality of magnet elements oriented along the system axis. A plasma containment portion defines an interior region, wherein an interior region of a plasma containment portion accommodates a plasma that is established by a rotating magnetic field component that is cooperatively established by the first transverse magnetic field and the second transverse magnetic field, and wherein the plasma is accelerated out of the plasma containment portion by magnetic forces to generate a propulsion force.
