Abstract: A three-dimensional inductive charging coil assembly and a method of making the same. The method can include patterning a first conductive layer affixed to a first surface of an insulating layer to form a coil configured to transmit or receive power, patterning a second conductive layer affixed to a second surface of the insulating layer opposite the first surface to form a conductive trace element, and electrically coupling the coil and the conductive trace element. The coil, insulating layer, and conductive trace element can be molded (e.g., simultaneously) into a three dimensional shape. In some embodiment, the molding can include a thermoforming process such as compression molding, vacuum forming, or the like.

Abstract: Methods of and systems for directing flux from a transmit coil to a receive coil within an inductive power transfer system are disclosed. For example, a transmit coil may be shielded with a contoured shield made from a ferromagnetic material. The contoured shield may contour to several surfaces of the transmit coil so as to define a single plane through which flux may be directed to a receive coil.

Abstract: A first component is coupled to a second component by one or more joints. Magnetic force between at least a first magnetic and second magnetic unit preloads the joint by placing the joint in compression. The first and second magnetic units may be respectively coupled to the first and second components. The magnetic force acts as a retentive force between coupled components and/or the joint and operates to resist one or more tensile and/or other opposing forces. In some cases, the first magnetic unit may be a shield, such as a direct current shield, that protects one or more components from a magnetic field of the second magnetic unit.
