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 from a donor mobile device having a 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; and

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

wherein the donor wireless power transfer mechanism includes a primary coil and donor circuit elements and the receptor wireless power transfer mechanism includes a secondary coil, receptor circuit elements and a capacitor such that the donor circuit elements provide electric current to the primary coil producing a magnetic field that generates an electric current in the secondary coil and the receptor circuit elements thereby transferring power from donor mobile device to the receptor mobile device, the capacitor storing electric charge that increases battery life when the capacitor is discharged.

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 method for transferring power to a receptor mobile device from a donor mobile device, comprising;

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

determining a donor power threshold using a wireless transmit application; and

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;

wherein the donor wireless power transfer mechanism includes a primary conductor and donor circuit elements and the receptor wireless power transfer mechanism includes a secondary conductor and receptor circuit elements such that the primary conductor and secondary conductor act as capacitor plates and air between the primary conductor and the secondary conductor acts as a dielectric such that when electric current is provided to the primary conductor form the donor circuit elements, the primary conductor and the secondary conductor act as a capacitor such that on discharge, generates electric current to the receptor circuit elements.

7. The method of claim 6, further comprising determining whether the donor mobile device has been reduced to the donor power threshold.

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