20080290974 | Proportional solenoid with armature motion sensing - A shielded solenoid for a solenoid operated valve having a solenoid body and an annular coil of electrical wire in the solenoid body. An armature of magnetic material is rectilinearly movable with respect to the body. A magnet holder is fastened to the armature and has a permanent magnet fixedly oriented thereon. A shield member covers the magnet holder and the permanent magnet. The shield member is configured to shield a Hall effect sensor from any significant electromagnetic field produced by the coil when effecting rectilinear movement of the armature. The hollow shield member has a non-metallic plug closing one end thereof. The plug has the Hall effect sensor oriented therein to closely oppose the magnet on the magnet holder so that movement of the armature and resulting corresponding movement of the magnet will cause the Hall effect sensor to produce a signal indicative of movement of the armature. | 11-27-2008 |
20100079227 | FLUX MITIGATION - Aspects relate to mitigation of a magnetic field produced by one or more units to be shipped such that a magnitude of magnetic field measured is maintained at or below a threshold level. A counter-flux is applied through the use of one or more magnets, magnet arrays, or a geometrical arrangement of magnet arrays. The strength of the counter-flux is varied by altering size, shape, number, polarity and/or location of the one or more magnets or magnet arrays. The one or more magnets or magnet arrays can be constructed as standard assemblies and/or customized magnet assemblies. Additionally, magnet tiles or configurations can provide a return path for stray field leakage and mitigation. Additionally or alternatively, the placement and orientation of the magnets or magnet arrays allows the flux of one or more units to be mitigated, thus, allowing more than one unit to be shipped at the same time. | 04-01-2010 |
20100321138 | SEPARATE TYPE MAGNETIC SHIELD APPARATUS - It is an object of the present invention to provide a separate type magnetic shield apparatus which has high access performance to a magnetically shielded space, in which magnetic shielding is very effectively achieved. In the separate type magnetic shield apparatus, first and second conductors | 12-23-2010 |
20110018662 | METHOD OF USING A DIAMAGNETIC MATERIALS FOR FOCUSING MAGNETIC FIELD LINES - The use of diamagnetic materials in a magnetic field, into which a paramagnetic material is introduced, as a focuser for focusing the magnetic field lines in the paramagnetic material is described. | 01-27-2011 |
20120249274 | MAGNETIC SHIELD, PROGRAM, AND SELECTION METHOD - A magnetic shield including a first layer and a second layer and shielding an environmental magnetic field is obtained by manufacturing the first layer that is configured by a first material and that includes a hollow portion on the inside and the second layer that is configured by a second material that is different from the first material and which is a hollow member and placing the second layer in the hollow portion of the first layer. With the magnetic shield, in regions between the first layer and the second layer, a material in which the relative magnetic permeability at the strength of the magnetic field at a region that is next to the second layer is high compared to the relative magnetic permeability of the first material at the strength of the magnetic field is selected as the second material that configures the second layer. | 10-04-2012 |
20120280773 | Magnetoresistive Shield with Coupled Lateral Magnet Bias - In accordance with various embodiments, a magnetic shield for a magnetoresistive (MR) element has one or more lateral hard magnets and a coupling layer contactingly adjacent both the MR element and the hard magnet. The coupling layer concurrently magnetically decouples the MR element while magnetically coupling the hard magnet. | 11-08-2012 |
20120280774 | Magnetoresistive Shield with Lateral Sub-Magnets - A magnetic shield for a magnetoresistive (MR) reader has one or more lateral hard magnets and a ferromagnetic shielding layer with at least one hard sub-magnet in a lateral notch in the shielding layer. The notch allows the shielding layer to contact the sub-magnet on surfaces along multiple normal planes. | 11-08-2012 |
20120286910 | SHIELDED TRANSDUCER FOR PLUMBING FIXTURE - Plumbing fixtures are disclosed having acoustic electromagnetic transducers mounted thereon to transmit music or other vibrations to the fixture interior. The mounting assembly provides for a shield that reduces exposure of those in the fixture to a magnetic field generated by the transducers. In one form there is a post extending from the transducer, through the shield, to a bracket on the housing. Other structures are provided to facilitate removability of the shield and transducer for maintenance purposes. | 11-15-2012 |
20140191830 | SYSTEM AND METHOD FOR AFFECTING FLUX OF MULTI-POLE MAGNETIC STRUCTURES - A shunt plate is provided that is associated with a first side of a multi-pole magnetic structure. The shunt plate provides a magnetic short between opposite polarity magnetic sources on the first side of said magnetic structure, the magnetic short causing a magnetic flux of said opposite polarity magnetic sources to be routed from said first side of the magnetic structure through said magnetic structure to the second side of said magnetic structure. The thickness of the shunt plate is selected by determining the integrated flux across a magnetic source of the magnetic structure such that the corresponding flux density in the shunt plate does not substantially exceed the flux density saturation level of a cross section of the shunt plate. | 07-10-2014 |
20160111192 | MAGNETIC FIELD STRUCTURES, FIELD GENERATORS, NAVIGATION AND IMAGING FOR UNTETHERED ROBOTIC DEVICE ENABLED MEDICAL PROCEDURE - A magnetic field generating apparatus comprises two or more co-facing, coaxial magnetic field generators configured to generate equivalent magnetic fields directed toward a symmetrically central convergence plane; a magnetically shielding encasement configured to contain all of the associated magnetic fields generated by the coaxial magnetic field generators; and articulation frames and supports for positioning of the apparatus about a fixed point, wherein the generated magnetic fields are counter-rotated relative to one another. | 04-21-2016 |
