  • High-density, folded electromagnetic coil
    Patent number: 10181375
    Abstract: In accordance with one embodiment, a High-Density, Folded Electromagnetic Coil comprises a plurality of wire spirals that are folded into substantially semicircles, stacked against each other, and have a common centerline to form a substantially high-density, electromagnetic coil. The wire spirals are electrically connected such that electric current flows through each wire spiral in series and in the same direction through each wire spiral.

  • Enhanced flux-density magnet
    Patent number: 9960647
    Abstract: One embodiment of an enhanced flux-density magnet comprises a magnetic material with two magnetic poles and one magnetic pole-area smaller than the other magnetic pole-area. Because the magnetic field at both pole-areas is equal but the magnetic pole-areas are unequal, the magnetic flux-density is proportionally greater at the magnetic pole with a smaller area than the magnetic pole with the larger area and greater than if the magnetic pole-areas were equal.
