Wirelessly charged devices
First Claim
1. A wearable device, comprising:
- a device housing; and
an inductive charging coil assembly disposed within the device housing and comprising;
a ferritic core having a joint region, a first leg and a second leg, the first leg extending away from a joint region in a first direction and the second leg extending away from the joint region in a second direction different from the first direction,a first inductive receiving coil wrapped around a portion of the first leg and oriented in the first direction, anda second inductive receiving coil wrapped around a portion of the second leg and oriented in the second direction, wherein the joint region, the first leg, and the second leg together form a monolithic structure such that the joint region is disposed between the first leg and the second leg and the first inductive receiving coil and the second inductive receiving coil are spaced apart to form a gap at the joint region.

Abstract
This disclosure relates to the inductive charging of portable electronic devices. In particular, a charging assembly is disclosed that allows a portable electronic device to be charged in multiple orientations with respect to a charging device. The charging assembly includes two or more separate inductive receiving coils. The inductive receiving coils can be arranged orthogonally with respect to one another by wrapping one or more secondary receiving coils around a ferritic core having two legs extending in different directions from a joint region. By orienting the receiving coils orthogonally with respect to one another, the likelihood of at least one of the receiving coils being aligned with a charging field emitted by a charging device increases substantially.
