DISTRIBUTED CHARGING OF MOBILE DEVICES
First Claim
1. A system for distributed charging of mobile devices, comprising:
- a secondary coil or receiver associated with a mobile device; and
wherein, 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.

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.
