Abstract

Embodiments of the disclosure may include a system for transferring power, the system having a donor mobile device. Such a donor mobile device may include processor(s) and a donor wireless power transfer mechanism coupled to the processor(s). In addition, the donor mobile device may include software application(s) that: (i) configure the donor wireless transfer mechanism on the donor mobile device to initiate power transfer; and (ii) transfer power using the donor wireless transfer mechanism. The system may also have a receptor mobile device including processor(s) and a receptor wireless power transfer mechanism coupled to the processor(s). Further, the receptor mobile device may include software application(s) that: (i) configure the receptor power transfer mechanism on the receptor mobile device to receive power; and (ii) receive and convert received power into electric current using the receptor power transfer mechanism.

Claims

1. A method for transferring power to a receptor mobile device having a first battery from a donor mobile device having a second battery, comprising;

configuring a donor wireless power transfer mechanism on the donor mobile device using a wireless transmit application;

configuring a receptor wireless power transfer mechanism on the receptor mobile device using a wireless receive application;

transferring power from donor mobile device to the receptor mobile device using the donor wireless power transfer mechanism and the receptor wireless power transfer mechanism until the first battery reaches a specific power threshold;

receiving and converting received power into electric current using the receptor wireless power transfer mechanism;

providing, by the donor wireless transfer mechanism, an electric current to a primary coil, the primary coil further providing electric current to a secondary coil in the receptor wireless transfer mechanism through a magnetic field; and

storing an electric charge in a capacitor included in the receptor wireless power transfer mechanism thereby increasing battery life of the first battery when the capacitor is discharged, the battery life increase based on the specific power threshold.

2. The method of claim 1, further comprising configuring a donor power threshold using a wireless transmit application.

3. The method of claim 2, further comprising determining whether the donor mobile device has been reduced to the donor power threshold.

4. The method of claim 1, further comprising configuring a receptor power threshold using a wireless receive application.

5. The method of claim 1, further comprising determining whether the receptor mobile device exceeds the receptor power threshold.

6. A system for transferring power to a receptor mobile device having a first battery from a donor mobile device having a second battery, comprising:

a donor wireless power transfer mechanism on the donor mobile device that uses a wireless transmit application;

a receptor wireless power transfer mechanism on the receptor mobile device that uses a wireless receive application;

wherein the donor mobile device transfers power to the receptor mobile device using the donor wireless power transfer mechanism and the receptor wireless power transfer mechanism until the first battery reaches a specific power threshold;

wherein the receptor wireless power transfer mechanism receives and converts received power into electric current;

wherein the donor wireless transfer mechanism provides an electric current to a primary coil and the primary coil further provides electric current to a secondary coil in the receptor wireless transfer mechanism through a magnetic field; and

wherein a capacitor included in the receptor wireless power transfer mechanism stores an electric charge thereby increasing battery life of the first battery when the capacitor is discharged, the battery life increase based on the specific power threshold.
