Abstract: Systems and devices for wireless power transmission is provided. A system includes a ground assembly and a vehicle assembly. The ground assembly includes a primary coil and a magnetic permeable core. The vehicle assembly includes a secondary coil capable of being inductively coupled to the primary coil and one or more magnetic permeable wings disposed on top of the secondary coil. Each of the one or more magnetic permeable wings overlap the secondary coil such that each of the one or more magnetic permeable wings extend within and beyond a periphery of the secondary coil for generating additional coupling between the primary coil and the secondary coil.

Abstract: An arrangement for inductively supplying energy to electric or hybrid vehicles can permit power to be inductively transmitted without contact from a primary coil integrated into a roadway to a second coil located in the vehicle to be supplied. A primary coil can be embedded in a magnetizable concrete so that a magnetic field provided by the primary coil is concentrated toward the intended charging position of the secondary coil located in the vehicle. This can enable power transmission with low stray field and high efficiency.

Abstract: A magnetic device and method for making it involve a magnetic device specifically constructed of grains in a matrix. The matrix may be cement or plaster. The grains have an average diameter that is greater than their magnetic domains. The device may be applied to shielding applications for frequencies ranging from 100 kHz to 10 GHz. The shielding may be applied to walls of a building, consumer products such as magnetic disks, and the like. The grains may be any ferromagnetic material, including ferrite.

Abstract: An improved ferrite core, which is particularly suitable for transformers, is proposed, which proposes with respect to shapes derived from E-cores to create the middle bleb with an oval cross-section, whereby the longitudinal axis of the middle bleb is oriented parallel to the attachment plane and the longest axis of the oval cross-section resides vertically to this attachment plane. The core is symmetrically structured with respect to the mirror plane, which contains the longitudinal axis and which resides vertically to the attachment plane, and is particularly low in distortion.

Abstract: An inductive sensor on the basis of an annularly closed, soft-magnetic core (K) is disclosed wherein the current to be measured produces an inductive change within the annularly closed magnetic circuit, said inductive change being taken via a measurement winding (MW) wrapped around the core. In order to achieve a linear behavior within a broad range of measurement, the annularly closed core comprises core regions (KB) that comprise a magnetic composite powder material and, in particular, a ferrite polymer composite material (FPC).
