Abstract: A wireless power transfer system including a transmitting antenna with a first conductive helix wound about a first helical axis, and a first ground plane positioned adjacent to and angled orthogonally with the first helical axis. The wireless power transfer system additionally includes a receiving antenna with a second conductive helix wound about a second helical axis, and a second ground plane positioned adjacent to and angled orthogonally with the second helical axis. Furthermore, the wireless power transfer system further includes a conductive material connecting the first ground plane to the second ground plane.

Abstract: An inflatable container includes a first body having an inner wall defining at least a portion of a receptacle and an outer wall. The inner wall is attached to the outer wall such that a cavity is defined between the inner wall and the outer wall. A first foam is positioned within the cavity. The first foam is of a type that expands when exposed to air. At least one first valve is attached to the first body. The one or more first valves are in communication with the cavity and are configured to adjust from a closed position to an open position. The at least one first valve permits air to pass through the at least one first valve and into the cavity when in the open position and prevents air from passing through the at least one first valve and into the cavity when in the closed position.
