A coil module includes a substrate; a wireless charging coil formed in a substantially central portion of the substrate positioned on both surfaces of the substrate; and a first wireless communications coil which does not directly contact the wireless charging coil and is formed in the substantially central portion of the substrate on both surfaces of the substrate, wherein, in a region of the substrate in which the wireless charging coil and the first wireless communications coil are overlapped with each other, the wireless charging coil is formed on one surface of the region and the first wireless communications coil is formed on the other surface of the region, respectively.

Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.

A position sensor includes a flexible substrate formed into a three-dimensional (3D) shape. At least first and second field-sensing coils are formed in first and second respective layers of the flexible substrate, such that in the 3D shape the first and second field-sensing coils have first and second respective axes that are not parallel to one another.

An electrical system including one or more bodies having an underlying structure resembling a double helix may be used to produce useful electromagnetic effects for various applications, including therapy.

A power feeding coil unit includes a power feeding coil, and first and second auxiliary coils located outside of the region defined by a wire of the power feeding coil. The axis of the first auxiliary coil and the axis of the second auxiliary coil are substantially perpendicular to the axis of the power feeding coil. The power feeding coil and the first and second auxiliary coils simultaneously generate respective magnetic fluxes, each of which interlinks the corresponding one of the power feeding coil and the first and second auxiliary coils in a direction from the center to the outside of the power feeding coil unit.

A coil component includes an air-core coil embedded in a magnetic body constituted by resin and metal magnetic grains. Both ends of the coil are exposed on the surface of the magnetic body, and the side on which both ends are exposed is polished and etched to form terminal electrodes. To be specific, an underlying layer of metal material is formed across the surface of the magnetic body and the ends by means of sputtering, and then a cover layer is formed. Where the magnetic body contacts the underlying layer, the areas where the underlying layer is in contact with the resin ensure insulation, while the contact between the underlying layer and the exposed parts of the metal magnetic grains ensures adhesion, thus increasing the adhesion strength with respect to the terminal electrodes.
