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.

Abstract: An inductive power transmission platform includes a plurality of inductive power outlets connected to a common driver via individual power switches. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The switches may be configured to remain closed while current passes therethrough. The common driver may be used to manage the power drawn by the transmission platform to each of the inductive power outlets.

Abstract: A power providing system in which inductive power outlets are incorporated into a bounding surface of a workspace includes inductive power outlets having primary inductors connected to a power supply via a driver. The primary inductors may be inductively coupled to secondary inductors wired to an electric load to provide power thereto. The bounding surface may be a wall, floor, ceiling or the like. Various inductively enabled prefabricated materials are disclosed for incorporating into such bounding surfaces.

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.

Abstract: A pin-less power coupling arrangement comprising at least one pin-less power jack; the power jack comprising a primary coil shielded behind an insulating layer for inductive coupling to a pin-less power plug; said power plug comprising a secondary coil wherein said insulating layer is substantially flat and said power plug and said power jack may be aligned by an alignment means. Various such alignment means are discussed as are enabled surfaces for supporting inductive power jacks and inductive plugs coupled to various appliances.

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: 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.

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.

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 method and system to connect remote antennae and/or remote cellular sectors/sites to cellular base stations. The method and system described herein uses bi-directional optical wireless links, which transfer the information between the base station and the remote site, and vice versa, by single optical signal or several optical signals of different wavelengths. This method and system make it possible to place the antennae remote from the base station.
