  • Publication number: 20140354372
    Abstract: Systems for reducing magnetic coupling in integrated circuits (ICs) are disclosed. Related components and methods are also disclosed. The ICs have a plurality of inductors. Each inductor generates a magnetic flux that has a discernible axis. To reduce magnetic coupling between the inductors, the flux axes are designed so as to be non-parallel. In particular, by making the flux axes of the inductors non-parallel to one another, magnetic coupling between the inductors is reduced relative to the situation where the flux axes are parallel. This arrangement may be particularly well suited for use in diplexers having a low pass and a high pass filter.

    Abstract: At least one shield member interposed between primary and secondary windings of a transformer and connected to the primary and/or secondary windings forms a distributed parasitic capacitance between the shield member and either the winding to which it is not connected or another shield member connected to that winding. Connections are made to the respective transformer windings such that the voltage distributions thus developed cause complementary common mode noise to be conducted in opposite directions in respective portions of the parasitic capacitance such that net common mode current can be made arbitrarily small without requiring that both sides of the distributed parasitic capacitance have complementary or equal voltage distributions. Such complementary common mode currents can be achieved by dividing opposing shield members or developing a voltage distribution in a single shield member in accordance with Faraday's Law.

    Abstract: A method of manufacturing a leadless marker for localizing the position of a target within a patient. According to one embodiment, the method includes providing a ferromagnetic element; positioning a coil of an inductor at least around a portion of the ferromagnetic element, wherein the coil comprises a plurality of windings of a conductor; and positioning the ferromagnetic element such that the radiographic and magnetic centroids of the marker are at least substantially coincident. The marker does not have external electrical lead lines extending through the casing. The ferromagnetic element is at least partially within the inductor. The ferromagnetic element has a volume such that when the marker is in an imaging magnetic field having a field strength of 1.5 T and a gradient of 3 T/m, then the force exerted on the marker by the imaging magnetic field is not greater than gravitational force exerted on the marker.
