摘要： A coil for facilitating magnetic induction tomography imaging of a specimen, such as a human tissue specimen, using a single coil is provided. The coil can include a plurality of concentric conductive circular loops. The concentric conductive loops can be connected in series with connection traces without allowing the connection traces to distort the fields produced by the plurality of concentric conductive circular loops. The plurality of concentric conductive loops can be arranged in multiple planes (e.g. on a multilayer printed circuit board) as a two layer stack. The spacing between the planes or the plane separation distance can be selected such that mathematically the plurality of conductive loops can be treated as being located in a common plane for purposes of a quantitative analytical model used for magnetic induction tomography imaging.

摘要： Inductive components, such as transformers, can be improved by the inclusion of a magnetic core. However the benefit of having a core is lost if the core enters magnetic saturation. One way to avoid saturation is to provide a bigger core, but this is costly in the context of integrated electronic circuits. The inventor realized that the flux magnetic flux density varies with position in a magnetic core within an integrated circuit, causing parts of the magnetic core to saturate earlier than other parts. This reduces the ultimate performance of the magnetic core. This disclosure provides structures that delay the onset of early saturation, enabling a transformer to handle more power.

摘要： The invention relates to a reactor for application in a transport or distribution network for electrical energy and comprising at least one winding arranged in a metal housing, wherein means are arranged for applying an axial pressure force to the winding, wherein the metal housing forms part of the pressure means.
This renders superfluous the use of extra constructions for applying an axial pressure force to the reactor. This avoids the problems associated with such constructions, while the possibility is likewise created of giving the reactor a smaller, lighter and less expensive form.
According to a preferred embodiment a magnetic circuit is arranged inside the housing to screen the stray field generated by the winding, wherein at least a part of the magnetic circuit functions as means for transmitting from the housing the axial pressure force to be applied to the winding.
