Abstract: A conductor is provided for an electric machine having an axis, a radial direction extending outward from the axis, and a tangential direction perpendicular to the radial direction. The conductor includes a solid core, having radial faces substantially perpendicular to the radial direction of the electric machine and tangential faces substantially perpendicular to the tangential direction of the electric machine. At least one tangential depression is formed on at least one of the tangential faces. The tangential depression creates a tangential void within a rectangular envelope defined by the solid core. Therefore, the surface area of the solid core is greater than the surface area of the rectangular envelope.

Abstract: A fill control system includes a fuel storage vessel, a fuel inlet in fluid communication with the fuel storage vessel to provide fluid communication between a fuel source and the fuel storage vessel, and a fill control valve disposed between and in fluid communication with the fuel inlet and the fuel storage vessel, an actuation of the fill control valve causing a pressure level upstream thereof which emulates a full condition of the fuel storage vessel.
