Abstract: A power outlet locator for locating concealed inductive power outlet. A sensor is provided for detecting a signal emitted by an inductive power outlet. A processor uses the detected signal to compute location coordinates of the power outlet. A user interface is provided to communicate the location of the power outlet to a user.

Abstract: Non-resonant inductive power transmission wherein the driving voltage across a primary inductor oscillates at a frequency significantly different from the resonant frequency of the inductive coupling system. Embodiments of the invention include systems and methods for: power regulation using frequency control, fault detection using voltage peak detectors and inductive communication channels.

Abstract: A display device comprising an array of encapsulated pixels. The encapsulating pixel includes an optical element which is altered from a first optical state to a second optical state upon when a potential difference is generated across it. The optical element is in contact with two electrodes which are connected to a pixel driver for generating the potential difference. The encapsulated pixel is hermetically sealed from the environment by a sealing layer and the driver receives power wirelessly via an inductive power transmission system.

Abstract: A switching system configured to control a connection between a power supply and an inductive power outlet where the inductive power outlet includes at least one primary inductor configured to inductively couple with a secondary inductor associated with an inductive power receiver includes a circuit breaker configured to disconnect the inductive power outlet from the power supply, and a trigger switch configured to disable the circuit breaker when the inductive power receiver is brought into proximity with the inductive power outlet.

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.
