Abstract: A track element of a non-contact bearing extending in a length direction. The track element includes a conductive material strip having a facing surface with a height and width and a rear surface opposite the facing surfaces. The conductive material strip includes a slit extending in a height direction to form a first leg and a second leg, in which the first leg is bent in a zig-zag shape and the second leg is bent in a zig-zag shape that is complementary to the bending of the first leg. When the conductive material strip is viewed in a direction parallel to the facing surface, the first leg and the second leg cross each other at least once.

Abstract: Non-contact bearing system, such as a magnetic levitation system, having a geometry. The geometry includes a plurality of track elements arranged to nest together in a length direction. The plurality of track elements are shaped to define at least an upper and a lower null flux crossing and the plurality of nested track elements form a conductive metamaterial. Method for constructing a metamaterial null flux magnetic levitation track with tessellating elements of stamped conductors.

Abstract: A testing apparatus includes a chamber, having an interior maintained at a predetermined pressure, a rotor rotatably disposed within the interior of the chamber, and a sensor disposed within the interior of the chamber. When the rotor rotates, the at least one sensor measures a testing characteristic of an object disposed within the interior of the chamber as the object interacts with the rotating rotor. A method includes setting a predetermined pressure of a chamber, rotating a rotor, and maintaining a gap between a surface of an object to be tested and a surface of the rotor by adjusting, with an actuator, the object to be tested or the rotor based upon a change, as measured by a laser, in the dimension of the object to be tested or the rotor.
