METHODS AND SYSTEMS FOR MAGNETIC SHIELDED TRANSMITTER SYSTEM

Abstract: in one aspect, a quadratic ferrite cube, wherein the quadratic ferrite cube comprises a hollow interior portion, wherein quadratic ferrite cube comprises a geometric shape that exhibits a same magnetic performance in an x direction, a y direction, and a z direction; a plurality of copper windings placed on an external portion of the quadratic ferrite cube; and a control and driving circuitry located inside the hollow interior portion, wherein the quadratic ferrite cube is used to generate a x, y, z magnetic field, and wherein the quadratic ferrite cube is used as a shielded room for a control and driving circuitry by generating the x, y z magnetic field in a range 20 khz to 50 khz for a magnetic based position system.
