1. A system comprising:
- a first device and a second device each having a processor, wherein the first device is not in physical contact with the second device, the first device including a first wireless charging power transmitter and a first wireless charging power receiver; and
at least one of the first device and second device having a power management system configured to;
compare attribute data from the first device with attribute data from the second device, wherein the attribute data of the first device includes a location of the first device; and
wherein the attribute data of the second device includes a location of the second; and
select a power transfer mode for the first device based on the comparison of the attribute data from the first and second devices, wherein the selection of the power transfer mode causes the first device to one of accept wireless charging power from another device and transmit wireless charging power to the other device.

Abstract
A first device may have a processor and a power management system configured to receive a request from a second device. The first device may receive attribute data from the second device and compare the attribute data of the second device to attribute data of the first device. The first device may then determine whether the second device is a qualifying device based on the comparison and it may also determine a power transfer mode of the first device based on whether the device is a qualifying device and on the attribute data of the first and second device.

10. A method comprising:
-
determining whether one of a first device and a second device controls a power management system to control at least an inductive transfer of power among the first and second devices; receiving, at the first device, a power transfer request from the second device; reading attribute data from the first device, wherein the attribute data of the first device includes a battery level threshold of the first device; determining whether to inductively transfer power from the first device to the second device based on the battery level threshold of the first device; reading attribute data from a third device, wherein the attribute data of the third device includes a battery level threshold of the third device; determining whether to inductively transfer power from the third device to the second device, wherein determining whether to inductively transfer power from the third device is based on both the battery level threshold of the third device and the battery level threshold of the first device; and inductively transferring power to the second device from one of the first device and the third device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A non-transitory computer-readable medium tangibly embodying computer-executable instructions, wherein the instructions cause a first device to:
-
manage inductive power transfer operations of the first device and a second device; detect a third device; read attribute data from each of the first device, the second device, and the third device, wherein (i) the attribute data of the first device includes a battery level attribute of the first device, (ii) the attribute data of the second device includes a battery level attribute of the second device, and (iii) the attribute data of the third device includes a battery level attribute of the third device; and determine whether to engage in an inductive power transfer directly between the first device and the second device based on the battery level attribute of the first device, the battery level attribute of the second device, and the battery level attribute of the third device. - View Dependent Claims (19)

20. A non-transitory computer-readable medium tangibly embodying computer-executable instructions, wherein the instructions cause a first device to:
-
manage inductive power transfer operations of the first device and a second device; read attribute data of the first device and the second device, wherein the attribute data of the first device includes a first battery level attribute of the first device; determine whether to engage in an inductive power transfer between the first device and the second device based on the battery level attribute of the first device; detect a third device; receive attribute data from the third device, wherein the attribute data from the third device includes a battery level attribute of the third device, and wherein the determination of whether to engage in the inductive power transfer between the first device and the second device is further based on the battery level attribute of the third device; and cause the first device to compare a location of the third device with at least one of a location of the first device and a location of the second device.
