A magnetic core according to one embodiment of the present invention includes a first magnetic core having pure iron or an Fe-based alloy and a second magnetic core disposed to surround at least a part of an outer circumferential surface of the first magnetic core and including ferrite.

Smartcards with metal layers manufactured according to various techniques disclosed herein. One or more metal layers of a smartcard stackup may be provided with slits overlapping at least a portion of a module antenna in an associated transponder chip module disposed in the smartcard so that the metal layer functions as a coupling frame. One or more metal layers may be pre-laminated with plastic layers to form a metal core or clad subassembly for a smartcard, and outer printed and/or overlay plastic layers may be laminated to the front and/or back of the metal core. Front and back overlays may be provided. Various constructions of and manufacturing techniques (including temperature, time, and pressure regimes for laminating) for smartcards are disclosed herein.

A magnetic film includes iron and copper distributed between opposing first and second major surfaces of the magnetic film. The copper has a first atomic concentration C1 at a first depth d1 from the first major surface and a peak second atomic concentration C2 at a second depth d2 from the first major surface, d2>d1, C2/C1≥5.

A surface mount device inductor has a package casing sized to attenuate electromagnetic coupling between the inductor coils of the surface mount device inductors. The surface mount device inductor includes an inductor coil, an anode structure disposed over a first end of the inductor coil and a cathode structure disposed over a second end of the inductor coil opposite the first end, the cathode structure being spaced apart from the anode structure. One or both of the anode structure and the cathode structure comprise a shield portion disposed at least partially over the inductor coil to thereby reduce electromagnetic coupling between adjacent surface mount device inductors. The package casing makes the surface mount device inductors self-shielding. The surface mount device inductors can be incorporated into a radiofrequency module, and can be incorporated into a front end system of a wireless mobile device.

A minimally invasive circulatory support platform that utilizes an aortic stent pump or pumps. The platform uses a low profile catheter-based techniques and provides temporary and chronic circulatory support depending on the needs of the patient. Further described is a wirelessly powered circulatory assist pump for providing chronic circulatory support for heart failure patients. The platform and system are relatively easy to place, have higher flow rates than existing systems, and provide improvements in the patient’s renal function.
