Abstract: A system and method are provided for wirelessly transmitting energy from a transmitter platform to a receiver platform. The system reduces the number of coils on the receiver platform to one, while the remaining coils are located on the transmitter platform. The spacing of the coils on the transmitting platform can be adjusted to optimize the magnetic flux transfer to the single coil on the receiving platform based on the unique distance between the transmitter and receiver platforms.

Abstract: A method for power delivery comprising the steps of coupling a polymer electrolyte membrane fuel cell (PEM-FC) to a load system, wherein the PEM-FC is powered by hydrogen gas and oxygen; using a blower to deliver oxygen to the PEM-FC; using an automated electro-chemical control system to monitor PEM-FC hydrogen gas levels, PEM-FC voltage, and load demands; determining that more hydrogen gas is required to fuel the PEM-FC, mixing sodium borohydride, a catalyst, and water, releasing hydrogen gas and delivering the hydrogen gas to the PEM-FC, and transferring the resulting power from the PEM-FC to the load system.

Abstract: A wireless power transfer system includes a receive coil system nested within a transmit coil system forming a closed magnetic circuit. The transmit coil system includes a non-planar tapered transmit coil disposed within a tapered ferrite housing and a layer of insulating material surrounding the non-planar tapered transmit coil and the tapered ferrite housing. The receive coil system includes a ferrite plug comprising a column portion centrally secured to a plate portion, a non-planar receive coil wound around the column portion, a layer of insulating material surrounding the column portion and the non-planar receive coil, and a hemispherical covering surrounding the insulated column portion and non-planar receive coil. The non-planar receive coil has a smaller diameter than the non-planar tapered transmit coil. The maximum outside diameter of the hemispherical covering is less than or equal to the minimum inside diameter of the non-planar tapered transmit coil.
