  • 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.

  • In situ bed chair
    Patent number: 10154931
    Abstract: In accordance with one embodiment, an In situ Bed Chair (IBC) rotates back and forth and has elevating and lowering bed sections. In a second embodiment, the IBC converts from a flat bed into a chair or vice a versa such that a patient can remain in place during the conversion. The chair has wheels that enable easy transport of the patient to other locations.

  • 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.

  • Folded electromagnetic coil
    Patent number: 8487486
    Abstract: In accordance with the embodiment a folded electromagnetic coil comprises an electrically conducting wire looped and folded many times such that two or more semicircular sections are formed with approximately the same centerline and the same coil opening such that a supported-magnet can pass unobstructed though the coil center.
