A conductorless charging and power system for electronic appliances and method for communicating power to a power receiver employing wireless energy transmission are disclosed. The remote charging system includes a power transmission unit, which transmits energy as a directional power beam, and a power receiver system that receives the transmitted energy. The power receiver system is preferably incorporated in an appliance and includes an energy receptor capable of receiving the wireless power beam and transferring the energy from the beam to an energy storage device included in the appliance. The power transmission unit receives and tracks a power request signal from the power receiver system to track the power receiver system location during energy transmission. Data streams may be incorporated into the wireless signals of the remote charging system, allowing the remote charging system to function as a communications pathway as well as a power delivery system.

DETAILED DESCRIPTION Briefly stated, the invention in simplified form comprises a power transmission unit and a power receiver system.
In some embodiments there are a plurality of power transmission units, each interconnected to a power source such as, for instance, the existing electrical power transmission grid.
Each power transmission unit (PTU) includes a power transmitter selectively activatable between the on and off condition.
In the on condition, the power transmitter transforms energy from the power source into a directionally transmitted conductorless power beam.
The power transmission unit also preferably comprises communication components for sending and/or receiving a communication signal and a power unit controller operably connected to both the communication device and power transmitter.
The power unit controller device is preferably a logic type device incorporating microprocessors and functions to control the overall operation of the power transmission unit.
In other embodiments the power transmission unit includes safety devices, signal locating and tracking capabilities as well as a device or devices to change the focus and/or orientation of the directional power beam transmitted by the power transmitter.
The power receiving system (PRS) is preferably comprised of a number of operably interconnected components.
The PRS will include an energy receptor, such as an antenna, receptor/converter or combination receiver/antenna (rectenna).
The energy receptor receives the power beam transmitted from the power transmitter.
The PRS will also comprise an energy converter, which converts the energy received by the receptor to a form capable of storage in an energy storage device.
A power usage monitor monitors the energy level in the energy storage device and preferably the energy being expended and energy being received by the energy receiving means.
A transmitter/locator or "translocator" is operably connected to the power usage monitor.
The translocator functions to transmit a translocator signal from a translocator antenna
