Abstract
A system includes at least one active energy transfer coil and a first passive energy transfer coil. The active energy transfer coil is configured to couple with a power supply. The at least one active energy transfer coil has an active coupling range. The first passive energy transfer coil is magnetically coupled to the active energy transfer coil and is located within the active coupling range. The first passive energy transfer coil has a passive coupling range. The first passive energy transfer coil is configured to provide energy to a first device located within the passive coupling range and based on energy received from the at least one active energy transfer coil.
