Methods and devices for inductive coupling into power lines
First Claim
1. An electronic device including a housing having a back surface, comprising:
- a rechargeable battery;
a capacitor;
an inductor coil connected to the capacitor, the inductor coil being disposed around an axis oriented perpendicular to the back surface;
a rectifier circuit connected to the inductor coil to output a direct current (DC);
a DC-DC converter connected to the rectifier circuit, configured to trickle charge the battery with current received from the rectifier circuit;
a test load switchably connected to the DC-DC converter; and
a feedback circuit configured to detect a voltage level of the test load and provide an indication of the voltage level,wherein the voltage level of the test load is based on a position of the electronic device.
