Abstract: A system for inductive charging of electronic devices is disclosed. An inductive charger includes an enclosure with a charging surface, an inductive charging coil, and a metallic shield layer. The coil includes a spiral-shaped conductor that transmits power through the charging surface with an alternating magnetic field when an electronic device is positioned in proximity to the charging surface. The shield layer is positioned between the conductor and the charging surface such that the shield layer covers the conductor, and it provides a frequency-dependent response in which transmission of electromagnetic power through the shield layer is allowed in the frequency range while transmission of electromagnetic interference noise through the first shield layer is attenuated at frequencies higher than the frequency range.

Abstract: A power source, charging system, and inductive receiver for mobile devices. A pad or similar base unit comprises a primary, which creates a magnetic field by applying an alternating current to a winding, coil, or any type of current carrying wire. A receiver comprises a means for receiving the energy from the alternating magnetic field and transferring it to a mobile or other device. The receiver can also comprise electronic components or logic to set the voltage and current to the appropriate levels required by the mobile device, or to communicate information or data to and from the pad. The system may also incorporate efficiency measures that improve the efficiency of power transfer between the charger and receiver.

Abstract: A system and method for distributed charging of mobile devices. In accordance with an embodiment, the system comprises a secondary coil or receiver associated with a mobile device. When the mobile device is placed in proximity to a base unit having one or more primary coils, each primary coil having a generally planar shape so that when a current is passed through the primary coil a magnetic field is generated in a direction substantially perpendicular to the plane of the primary coil, the perpendicular magnetic field is used to inductively generate a current in the secondary coil or receiver associated with the mobile device, to charge or power the mobile device. In accordance with various embodiments the system can incorporate efficiency measures that improve the efficiency of power transfer between the charger and receiver.

Abstract: Provided is a combination of a receiver unit and a mobile device and/or battery, the device and/or battery capable of being inductively powered and/or charged by the receiver unit, the unit being a component of or electrically connected to the mobile device or battery. The receiver unit comprises a receiver coil and a communication and control system. The receiver coil generally has a planar surface, and the receiver unit is capable of receiving energy from a base unit via an inductive magnetic field and using the energy to power and/or charge the mobile device or batter. The communication and control system in the receiver unit regulates an appropriate power, voltage and/or current value of an output of the receiver unit to charge or power the mobile device or battery.
