1. A system comprising:
- a base unit, the base unit comprising;
a transmitter configured for wireless power delivery, the transmitter comprising a coil comprising a magnetic core;
a battery coupled to the transmitter;
a controller coupled to the battery and the transmitter and configured to cause the transmitter to selectively transmit power from the battery; and
a housing enclosing the transmitter, the battery, and the controller;
a body-worn repeater comprising a repeater coil configured to receive wireless power from the base unit;
a wearable electronic device comprising a further coil configured to receive wireless power from the body-worn repeater;
wherein the body-worn repeater is positioned between the base unit and the wearable electronic device, and wherein the repeater coil is larger than that of the further coil.

Abstract
Base units, systems and methods for wireless energy transfer are described. A wireless energy transfer system according to some examples includes a transmitter of wireless energy located within a communication device, such as a mobile phone, or attached to the communication device and a distance separated receiver located within an electronic wearable device other than the communication device, wherein the receiver is configured to receive wireless energy from the transmitter and convert the wireless energy into electrical power, which may be used to power the electronic wearable device.

11. A method comprising:
-
positioning a base unit proximate a body-worn repeater, wherein the base unit comprises a transmitting coil for wirelessly transmitting power to a receiving coil of the body-worn repeater, and wherein the position proximate the electronic device is defined by a distance between the base unit and the body-worn repeater less than a charging range of the base unit; wirelessly transmitting power from the base unit to the body-worn repeater while the base unit remains within the charging range of the body-worn repeater; and wirelessly transmitting power from the body-worn repeater to a wearable electronic device having a further receiving coil, wherein a distance between the body-worn repeater and the wearable electronic device is smaller than a distance between the base unit and the wearable electronic device, and wherein the receiving coil of the body-worn repeater is larger than the further receiving coil of the electronic wearable device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
