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, each bit having a logic state selected from logic state 1 and logic state 0;
assign pulses having a first characteristic frequency to represent logic state 0 and assign pulses having a second characteristic frequency to represent logic state 1 wherein at least one of said first characteristic frequency and said second characteristic frequency is selected from a predefined set of characteristic frequencies; and
transmit the digital communication such that pulses having any of said set of characteristic frequencies are all interpreted as the same logic state.

Abstract
The disclosure relates to inductive charging systems comprising at least one power access point (PAP) comprising a primary inductor connectable to a power supply, a PAP credential characterizing said PAP and a charger link comprising at least one wireless communication component; at least one device comprising a secondary inductor, a device credential characterizing said device and a device link comprising at least one wireless communication component; and a power controller comprising a communicator comprising at least one wireless communication component and a server having a database. The disclosure further relates to methods of controlling the inductive charging performed by an inductive charging system.

17. A method for communicating digital signals from an inductive power receiver, comprising:
-
constructing a digital communication comprising multiple bits of information, each bit having a logic state selected from a first logic state and a second logic state; assigning pulses having a first characteristic frequency to represent the first logic state and assigning pulses having a second characteristic frequency to represent the second logic state wherein at least one of said first characteristic frequency and said second characteristic frequency is selected from any one of a set of characteristic frequencies; and transmitting said digital communication from said inductive power receiver such that pulses having any frequency of said set of characteristic frequencies are all interpreted as the first logic state, or all interpreted as the second logic state. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
