1. A method of forming a wireless power receiving unit, comprising:
- forming a first receiving coil of a device to be charged by inductive coupling to a first transmitting coil; and
forming a second receiving coil of a device to be charged by inductive coupling to a second transmitting coil;
the second receiving coil being disposed at an angle to a plane of the first receiving coil, the first receiving coil and the second receiving coil to couple in parallel to a receiving circuit.

Abstract
Techniques of forming a wireless power receiving unit are described herein. The techniques may include forming a first receiving coil of a device to be charged by inductive coupling to a first transmitting coil. The techniques may include forming a second receiving coil of a device to be charged by inductive coupling to a second transmitting coil. The second receiving coil is disposed at an angle to a plane of the first receiving coil, and the first receiving coil and the second receiving coil are formed to connected in parallel to a receiving circuit.
