  • Patent number: 8749097
    Abstract: A signal transfer system for controlling power transfer across an inductive power coupling. A transmission circuit associated with an inductive power receiver is configured to transmit a control signal to a reception circuit associated with an inductive power outlet. The transmission circuit includes an ancillary load and a switching unit for modulating power drawn by a secondary inductive coil according to the control signal. The reception circuit is configured to monitor power provided to a primary inductive coil thereby detecting the modulated control signal. The signal transfer system may be used to regulate the power supplied by the inductive coupling and to detect the presence of the secondary coil.
