Patent ID: 8410775

Claim:
A method for determining a location of a first transducer assembly with respect to a second transducer assembly, the method comprising: at the first transducer assembly, receiving magnetic field signals from the second transducer assembly; and based on magnitudes of the magnetic field signals received on the first transducer assembly, determining a location of the first transducer assembly with respect to the second transducer assembly, wherein the determination of the location of the first transducer assembly with respect to the second transducer assembly affects a transmission of data information between the first transducer assembly and the second transducer assembly, wherein the first transducer assembly including M uniquely oriented transducers, where M is an integer equal to one or more, the second transducer assembly including N uniquely oriented transducers, where N is an integer equal to one or more, and wherein the M uniquely oriented transducers in the first transducer assembly are substantially orthogonal with respect to each other and the N uniquely oriented transducers in the second transducer assembly are substantially orthogonal with respect to each other.
