Claim Text:
1. An apparatus configured to transmit power via a magnetic field, the apparatus comprising: an antenna circuit configured to inductively transmit power via the magnetic field at a magnetic field strength level sufficient to charge or power a receiver device; a presence detection sensor configured to use a sensor signal other than the transmitted power and which is configured to sense a movement of a living being; and a controller configured to adjust the magnetic field strength level in response to detecting the presence of the living being, the controller further configured to provide, during a time period when the magnetic field strength is adjusted to a reduced level in response to detecting the presence of the living being, an indication that the antenna circuit is positioned relative to the receiver device to transmit a sufficient level of power to the receiver device.
