Abstract

In one example, a system comprises an electronic auxiliary device with a receiving inductive charging coil connected to it. The system further comprises a handheld electronic apparatus comprising a power source and a transmitting inductive charging coil. The handheld electronic apparatus further comprises a controller configured to cause a wireless electrical energy transfer from the transmitting inductive charging coil to the receiving inductive charging coil, in response to determining that the transmitting inductive charging coil of the handheld electronic apparatus is in proximity to the receiving inductive charging coil connected to the electronic auxiliary device.

Claims

1. A system, comprising:

an electronic auxiliary device with a receiving inductive charging coil connected to said electronic auxiliary device; and

a handheld electronic apparatus comprising a power source and a transmitting inductive charging coil,

wherein the handheld electronic apparatus further comprises a controller configured to cause a wireless electrical energy transfer from the transmitting inductive charging coil to the receiving inductive charging coil, in response to determining that the transmitting inductive charging coil of the handheld electronic apparatus is in proximity to the receiving inductive charging coil connected to the electronic auxiliary device.

2. The system as claimed in claim 1, wherein the electronic auxiliary device does not include a battery.

3. The system as claimed in claim 1, wherein the electronic auxiliary device and the receiving inductive charging coil are wearable.

4. The system as claimed in claim 3, wherein at least one of the wearable electronic auxiliary device and the receiving inductive charging coil is embedded in a piece of fabric.

5. The system as claimed in claim 4, wherein the piece of fabric comprises a holder in proximity to the receiving inductive charging coil and configured to receive the handheld electronic apparatus.

6. The system as claimed in claim 1, wherein the electronic auxiliary device comprises at least one of a sensor, an illuminator, a scent diffuser, and an insect repellent.

7. The system as claimed in claim 1, wherein at least one of the electronic auxiliary device and the handheld electronic apparatus further comprises a fastener configured to attach the electronic auxiliary device and the handheld electronic apparatus to each other.

8. The system as claimed in claim 7, wherein the fastener comprises a magnet.

9. The system as claimed in claim 1, wherein the proximity to the receiving inductive charging coil consists of distances less than or equal to one millimeter.

10. A method, comprising:

determining that a transmitting inductive charging coil of a handheld electronic apparatus is in proximity to a receiving inductive charging coil connected to an electronic auxiliary device, the handheld electronic apparatus comprising a battery; and

causing, by a controller of the handheld electronic apparatus, a wireless electrical energy transfer from the transmitting inductive charging coil to the receiving inductive charging coil.

11. The method as claimed in claim 10, further comprising stopping, by the controller of the handheld electronic apparatus, the wireless electrical energy transfer from the transmitting inductive charging coil to the receiving inductive charging coil in response to the transmitting inductive charging coil of the handheld electronic apparatus being out of proximity to the receiving inductive charging coil connected to the electronic auxiliary device.

12. The method as claimed in claim 10, wherein the electronic auxiliary device does not include a battery.

13. The method as claimed in claim 10, wherein the electronic auxiliary device and the receiving inductive charging coil are wearable.

14. The method as claimed in claim 13, wherein at least one of the wearable electronic auxiliary device and the receiving inductive charging coil is embedded in a piece of fabric.

15. The method as claimed in claim 14, wherein the piece of fabric comprises a holder in proximity to the receiving inductive charging coil and configured to receive the handheld electronic apparatus.

16. The method as claimed in claim 10, wherein the electronic auxiliary device comprises at least one of a sensor, an illuminator, a scent diffuser, and an insect repellent.

17. The method as claimed in claim 10, wherein at least one of the electronic auxiliary device and the handheld electronic apparatus further comprises a fastener configured to attach the electronic auxiliary device and the handheld electronic apparatus to each other.

18. The method as claimed in claim 17, wherein the fastener comprises a magnet.

19. The method as claimed in claim 10, wherein the proximity to the receiving inductive charging coil consists of distances less than or equal to one millimeter.

20. A handheld electronic apparatus, comprising:

a power source;

a transmitting inductive charging coil; and

a controller configured to cause a wireless electrical energy transfer from the transmitting inductive charging coil to a receiving inductive charging coil connected to an electronic auxiliary device, in response to determining that the transmitting inductive charging coil of the handheld electronic apparatus is in proximity to the receiving inductive charging coil connected to the electronic auxiliary device.
