An inductive coil assembly having multiple coils arranged at distinct
orientations to provide efficient inductive coupling of power or
communications or both to a device when the device is arranged at
different orientations with respect to the inductive primary coil. In one
embodiment, the inductive coil assembly includes three coils, each
oriented along one of the x, y and z axes of a standard Cartesian
three-dimensional coordinate system. The three separate coils provide
effective transfer of power and communication when the device is at
essentially any orientation with respect to the primary coil. In an
alternative embodiment, the multi-axis inductive coil assembly of the
present invention can function as a primary to inductively transmit power
or communication or both over a plurality of magnetic fields at distinct
orientations.
