WIRELESS POWER FOR PORTABLE ARTICLES
First Claim
1. A wireless electrical power system for use in a work area, said system comprising:
- a first wireless electrical power transmitter disposed in a surface that defines a portion of a work area;
a portable article configured to be positioned within the work area and movable between two or more locations in the work area;
a plurality of wireless electrical power receivers positioned at said portable article and configured such that a first of said wireless electrical power receivers receives electrical power from said first wireless electrical power transmitter when said first wireless electrical power receiver is adjacent or spaced from said first wireless electrical power transmitter by a distance that is less than or equal to a maximum transmission distance, wherein a second of said plurality of wireless electrical power receivers is positioned on a same side of said portable article and above said first wireless electrical power receiver; and
a second wireless electrical power transmitter positioned at said portable article, wherein said second wireless electrical power transmitter is configured to (i) receive electrical power directly from one of the plurality of wireless electrical power receivers, and (ii) provide electrical power to another wireless electrical power receiver of an electrical device positioned at said portable article when said another wireless electrical power receiver is adjacent or spaced from the second wireless electrical power transmitter by a distance that is less than or equal to a maximum transmission distance.

Abstract
A wireless electrical power system provides access to high voltage and/or low voltage electrical power at portable articles that are positionable at different locations within a work area, and substantially without the use of exposed cabling. The power system includes a portable article that is positionable at two or more locations within a work area. The work area is defined by a plurality of surfaces, at least one of which incorporates a wireless electrical power transmitter. The portable article incorporates a wireless electrical power receiver that is configured to receive electrical power from the wireless power transmitter when the wireless power receiver is sufficiently close to the wireless power transmitter. The portable article further includes an electrical power outlet that provides users in the work area with access to the electrical power.
