  • Publication number: 20100219697
    Abstract: An adjustable inductive power transmission platform includes inductive power outlets embedded into adjustable modules having multiple configurations. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The multiple configurations of the adjustable modules allow the position of the inductive power outlets to be adjusted to match the locations of inductive receivers to suit changing requirements.

  • Publication number: 20100194336
    Abstract: An inductively enabled audio speaker is disclosed configured to receive power inductively from an inductive power outlet. The audio speaker device has a voice coil which, as well as being able to produce an audible output, is further configured to function as a secondary inductor to inductively couple with a primary inductor. The inductively enabled audio speaker may be used to power an electrical device such as a Bluetooth earpiece, a telephone or the like.

  • Publication number: 20100072825
    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.

  • Publication number: 20100070219
    Abstract: An efficiency monitor for monitoring the efficiency of power transmission by an inductive power outlet. The efficiency monitor includes an input power monitor, for measuring the input power delivered to the primary coil, and an output power monitor, for measuring the output power received by the secondary coil. The input and output powers are used by a processor to determine an index of power-loss. A circuit breaker may be used to disconnect the inductive power outlet in case of excessive power loss.

  • Publication number: 20090257259
    Abstract: A current-triggered synchro-rectifier comprising an electronic switch configured to be in its ON setting when the current flowing through its cathode exceeds a predetermined threshold. The electronic switch may include a half-wave rectifier wired to the source terminal and the drain terminal of a MOSFET device, and a current monitor configured to monitor the drain-current flowing through the drain terminal. The current monitor sends a gate signal to the gate terminal such that the MOSFET is switched to its ON state when the drain-current exceeds a first threshold current and the MOSFET is switched to its OFF state when the drain-current falls below a second threshold current. Usefully, the synchro-rectifier may be incorporated into a full-wave rectifier.
