Abstract: Systems and methods for removing plaque from blood vessels by applying constant or time varying magnetic or electrical fields. In one embodiment a system includes winding configurations positioned about a central axis along which a body region may be placed. Each winding configuration generates a magnetic field in a direction which passes through the body region. A first winding configuration generates a first magnetic field component perpendicular to a second magnetic field component generated by a second winding configuration. In a related method for removing a deposit of plaque from a position along a wall of a blood vessel a magnetic field is applied which has a net direction predominantly orthogonal to the direction of the flow of blood through the vessel.

Abstract: A flux directed magnet and a method of manufacturing a flux-directed magnet in a reduced number of process steps is described and claimed. The present invention is, in an embodiment, a single-step manufacturing of flux directed magnet assemblies such as, but not limited to, Halbach arrays of arbitrary multipole order. Even tube-shaped flux directed magnet assemblies such as Halbach arrays with large aspect ratio, i.e. length to diameter, can be produced in single steps using the method of the invention. Alternatively, the present invention may be one step of a plurality of steps in a process for manufacturing of flux directed magnet assemblies.

Abstract: A power conversion and distribution system. In one embodiment low voltage source components convert a high voltage AC power source to a relatively low voltage supply and provide a direct current output. First superconductor wires carry current from the low voltage source components to a load, and second superconductor wires carry current from the load to the low voltage source components. Individual ones of the first wires are grouped with individual ones of the second wires so that wires connected to carry current in opposite directions are in such sufficiently close proximity that additives of self-fields generated by individual ones of the wires during power transmission result in reduction of the magnetic fringe field generated, thereby increasing the current carrying capacity of the wires.

Abstract: A system and method for generating a magnetic field in a rotating machine. In one embodiment, a primary winding assembly is configured to generate a rotatable magnetic field. The assembly is connected to receive multiple signals of different phases to effect field rotation. A set of secondary windings is positioned for generation of current based on magnetic coupling during the field rotation. The secondary windings include conductor capable of supporting superconducting current flow. A rotatable machine includes a stator and a rotor winding coupled for rotation with respect to the stator. The secondary windings are formed in a circuit for providing superconducting current through the rotor winding.

Abstract: An alternating current machine which generates a magnetic field or induces a voltage. In one embodiment the machine includes a stator and a rotor positioned about an axis. The stator includes three sets of coils, each set including at least a first pair of coil rows wired in series, with first and second members of the first pair configured to generate axial fields in opposite directions. Coil rows in the first pair of each set of coils are each arranged a different distance from the axis. A first member of the pair of the second set of coil rows is positioned between the first and second members of the pair of the first set of coil rows. The distance between the axis and the first member of the second pair of coil rows is intermediate the distances between the members of the first pair of coil rows and the axis.
