US 8,134,435 B2 · Flux mitigation

Abstract

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.

Dependent claims

A method for mitigating an amount of a measured flux field, comprising:

measuring a magnetic flux field of one or more units at a specified distance from the one or more units yielding a measured magnetic flux field;
and specifying, as a function of the measured magnetic flux field, a magnet array having a counter-flux estimated to maintain the magnetic flux field of the one or more units at the specified distance from the one or more units at or below a defined level;
remeasuring the magnetic flux field via a feedback loop yielding a new measured magnetic flux field;
and adjusting at least one of a strength of a magnet in the magnet array, a number of magnets in the magnet array, a polarity of the magnet in the magnet array, or a location of the magnet in the magnetic array based on the new measured magnetic flux field to maintain a horizontal magnetic field at or below the defined level at the specified distance from the one or more units.

A system for mitigation of a horizontal magnetic field, comprising:

a measurement component configured to collect first information relating to an amount of a horizontal magnetic field and a direction of the horizontal magnetic field measured at a given distance from one or more objects that produce the horizontal magnetic field;
a counter-flux component configured to generate, as a function of the first information, a recommendation of a magnet array for orientation around the one or more objects, wherein the magnetic array is estimated to produce a counter-flux that reduces the horizontal magnetic field at the given distance from the one or more objects below a defined level;
and a tuning component, incorporated in a feedback loop between the counter-flux component and the one or more objects, configured to alter at least one of a magnet strength, a number of magnets, a magnet polarity, or a location of the magnet array to maintain the horizontal magnetic field at the given distance from the one or more objects below the defined level based on second information, collected by the measurement component, relating to the amount of the horizontal magnetic field and the direction of the horizontal magnetic field measured at the given distance from the one or more objects.
