A system and method for transferring power does not require direct electrical
conductive
contacts. There is provided a primary unit having a power supply and a substantially
laminar surface having at least one conductor that generates an electromagnetic
field when a current flows therethrough and having an active area defined within
a perimeter of the surface, the at least one conductor being arranged such that
electromagnetic field lines generated by the at least one conductor are substantially
parallel to the plane of the surface within the active area; and at least one secondary
device including at least one conductor that may be wound about a core; wherein
the active area has a perimeter large enough to surround the conductor or core
of the at least one secondary device in any orientation thereof substantially parallel
to the surface of the primary unit in the active area, such that when the at least
one secondary device is placed on or in proximity to the active area in a predetermined
orientation, the electromagnetic field induces a current in the at least one conductor
of the at least one secondary device.
