System and method for providing and controlling inductive power charging
First Claim
1. An inductive power receiver having a signal transfer system to communicate with an inductive power outlet, the signal transfer system comprising circuitry configured to:
- construct a digital communication having multiple bits of information to allow data communication, each bit having a logic state selected from a logic state 1 and a logic state 0;
assign peak pulses having a first characteristic frequency to represent the logic state 0 wherein said first characteristic frequency is selected from any one of a first set of characteristic frequencies;
assign peak pulses having a second characteristic frequency to represent said logic state 1 wherein at least one of said second characteristic frequencies is selected from any one of a second set of characteristic frequencies; and
transmit the digital communication from the inductive power receiver to said inductive power outlet;
such that said peak pulses having any of said first set of characteristic frequencies are all interpreted as the logic state 0 and said peak pulses having any of said second set of characteristic frequencies are all interpreted as the logic state 1;
wherein at least one of said first set of characteristic frequencies and said second set of characteristic frequencies comprises more than one characteristic frequency.
