Abstract
A system for inductive power transmission includes at least one interface surface and a plurality of triangular coil elements positioned underneath the interface surface such that at least one edge of the respective triangular coil element is adjacent to an edge of at least one other of the triangular coil elements. Each of the triangular coil elements may be operable to inductively transmit power to at least one coil of at least one electronic device and/or inductively receive power from the coil of the electronic device. Each triangular coil element may be operable to detect the proximity of one or more inductive coils of one or more electronic devices and inductively transmit power upon such detection at different frequencies, power levels, and/or other inductive power transmission characteristics.
