  • Publication number: 20230230735
    Abstract: A soft magnetic composite comprising an iron or iron alloy ferromagnetic material coated with an oxide material. An interface between the ferromagnetic material and the layer of oxide contains antiphase domain boundaries. Two processes for producing a soft magnetic composite are also provided. One process includes depositing an oxide layer onto an iron or iron alloy ferromagnetic material by molecular beam epitaxy at a partial oxygen pressure of from 1×10?5 Torr to 1×10?7 Torr to form a coated composite. The other process includes milling an iron or iron alloy ferromagnetic material powder and an oxide powder by high-energy milling to form a mixture; compacting the mixture and curing in an inert gas atmosphere at a temperature from 500° C. to 1200° C. to form a soft magnetic composite.

  • Patent number: 8774915
    Abstract: Capacitor packaging according to the disclosure provides advantages particularly in connection to compact and/or complex-shaped medical devices (e.g., having limited interior volume defined by domed and/or irregular exterior surfaces). In addition, capacitors of the type shown and described herein can be utilized in relatively compact external defibrillators, such as automatic external defibrillators or clinician-grade, automated or manually-operated external defibrillators. In one form a plurality of capacitors having substantially flat exterior surfaces are placed in an abutting relationship between at least a pair of major surfaces and the major surfaces are spaced from an opposing or adjacent surface in a non-parallel configuration. In other forms, one or more exterior surface portions have a common and/or complex radius dimension (i.e., the surfaces are curved).
