LAPTOP AND PORTABLE ELECTRONIC DEVICE WIRELESS POWER SUPPLY SYSTEMS
First Claim
1. A wireless power supply system for inductively transferring power to a removable remote device, comprising:
- an inductive power supply for generating an electromagnetic field;
a cradle movable between a first position for supporting the remote device in a first orientation on a first power transfer surface and a second position for supporting the remote device in a second orientation on a second power transfer surface, each of said power transfer surfaces supporting said remote device within said electromagnetic field;
a first primary disposed on or within said cradle, said primary being operatively coupled to said inductive power supply to generate said electromagnetic field, said primary positioned to inductively couple with the remote device when placed in either said first orientation or said second orientation.

Abstract
The present invention provides wireless power supply systems intended primarily for use in powering and charging laptops and other portable electronic devices. In one embodiment, the power supply system includes a laptop cradle that can be used in upright or reclined positions. The cradle may be generally J-shaped and may house the wireless power supply circuit with the channel defined in the cradle. The cradle may includes a plurality of primaries to provide the ability to supply power to more than one device and/or to permit flexibility in placement of devices on or in the cradle. The present invention may also provide handheld cradles sized to power handheld devices that can be separate, standalone power supply stations or they can receive power from the laptop cradle. In an alternative embodiment, the power supply station may be incorporated into an adjustable height desktop pedestal. In yet another embodiment, the power supply station may be incorporated into a flexible desktop mat. The power supply station may be incorporated into a power block having one or more magnets that draw the power block into alignment. In another alternative embodiment, the power supply station is incorporated directly into items of luggage.
