POWER SOURCE, CHARGING SYSTEM, AND INDUCTIVE RECEIVER FOR MOBILE DEVICES
First Claim
1. A charger system for use with a mobile device for charging or powering the mobile device inductively, comprising:
- a base unit comprising one or more primary coils, the primary coils having a generally planar shape,a power supply for passing a current through the primary coils to generate a magnetic field in a direction substantially perpendicular to the plane of the primary coil; and
wherein the perpendicular magnetic field is used to inductively generate a current in one or more secondary coils within one or more mobile devices placed close to the base unit, to charge or power the mobile device.

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.

13. A mobile device capable of inductive powering or charging comprising:
-
a battery for powering a mobile device; and a receiver that is one of attached to, incorporated within, or coupled to the mobile device or the battery wherein the receiver comprises a secondary coil that inductively receives energy from a substantially perpendicular magnetic field generated by a base unit when the mobile device is placed close to the base unit, and wherein the energy so received is used to generate a current in the secondary coil and to charge or power the mobile device. - View Dependent Claims (14, 15, 16, 17, 18, 19)
