  "textContent": "Aspects of this disclosure are directed to a charging pad or apparatus having multiple controllable charging source coils that can sense the proximity of a load coil through inductive coupling. The system and method operate charging source coils in a low-current sensing mode when no load is near, a high-current charging mode when a load is not near, or other modes. The system and method can wirelessly charge one or more loads (e.g., battery-powered devices) placed on or in proximity thereof and selectably control the power and magnetic field of the plurality of source charging coils.",
