1. A system for wireless data transmission comprising:
- a plurality of primary coils operably coupled to be driven independently with a signal;
one or more secondary coil positioned in proximity to the primary coils and suitable for receiving the signal inductively;
whereinthe signal may be inductively transferred from one or more primary coil to one or more secondary coil.

Abstract
Multiple coil systems and methods are disclosed in which transmitter and receiver inductors, or coils, are coupled in a configuration for wirelessly transferring data and/or power among them. In preferred implementations, the systems and methods are used for transmitting data using pairs of coupled coils. One preferred aspect of the invention is that the coils are not permanently affixed in physical proximity to one another, but can be moved and/or interchanged.
