Wireless charging retail systems
First Claim
1. A wireless charging table comprising:
- a table top having an upper surface upon which one or more electronic devices can be placed;
a wireless charging transmitter positioned under the upper surface of the table top, the wireless charging transmitter comprising a plurality of transmitter coils that define a charging region at the upper surface of the table top, the plurality of transmitter coils including at least a first transmitter coil comprising;
a first loop portion coupled to a first node and a second node different from the first node, each node providing an avenue through which current can enter and exit out of the first loop portion of the coil;
a second loop portion coplanar with the first loop portion; and
a crossing portion comprising overlapping conductive paths that electrically couple the first loop portion and the second loop portion such that, when an electrical current is generated in the first transmitter coil, the electrical current flows through the first loop portion in a first rotational direction, and through the second loop portion in a second rotational direction opposite the first rotational direction; and
a power distribution system operatively coupled to the wireless charging transmitter, the power distribution system configured to receive power from an alternating current (AC) power source and distribute power to the wireless charging transmitter.
