Abstract

A system for validating refillable fuel cartridges is provided. The system includes a first device (302) and a second device (304). The first device is a refillable fuel cartridge that can be used in an electronic device (100). The first device includes a first access controller (306), a first transceiver (308), and a first fuel container (312). The first access controller authenticates the second device by using a first pre-specified authentication technique. The first transceiver receives an authentication query from the second device and the first fuel container stores fuel. The second device includes a second access controller (316), a second transceiver (318), and a second fuel container (322). The second access controller authenticates the first device by using a second pre-specified authentication technique. The second transceiver receives an authentication query from the first device and the second fuel container stores fuel.

Claims

1. A refillable fuel cartridge for an electronic device comprising:

a fuel container having a compartment to store fuel;

an access controller configured to authenticate another device using a first pre-specified authentication technique; and

a transceiver operatively coupled to the access controller, the transceiver being configured to receive an authentication query from the other device, the authentication query being used for authenticating the refillable fuel cartridge using a second pre-specified authentication technique.

2. The refillable fuel cartridge as recited in claim 1, wherein the other device is a refilling device or a consuming device.

3. The refillable fuel cartridge as recited in claim 1, wherein the fuel container is operatively coupled to the access controller and stores fuel that is capable of being oxidized to produce electrical energy.

4. The refillable fuel cartridge as recited in claim 3, wherein the fuel container is configured to authorize transfer of the fuel between the refillable fuel cartridge and the other device.

5. The refillable fuel cartridge as recited in claim 1, further comprising a memory being configured to store a status variable of the refillable fuel cartridge, wherein the access controller is configured to update the status variable of the refillable fuel cartridge to a valid value or an invalid value.

6. The refillable fuel cartridge as recited in claim 1, wherein the transceiver is configured to:

send a status variable of the refillable fuel cartridge to the other device; and

receive a request from the other device for updating the status variable of the refillable fuel cartridge.

7. The refillable fuel cartridge as recited in claim 1, wherein the transceiver comprises a Radio Frequency Identification (RFID) tag.

8. The refillable fuel cartridge as recited in claim 1, wherein each of the first pre-specified authentication technique and second pre-specified authentication technique is a challenge-response authentication technique.

9. An electronic device comprising:

a fuel container having a compartment to store fuel;

an access controller operatively coupled to the fuel container, the access controller being configured to authenticate a refillable fuel cartridge to be used with another device using a second pre-specified authentication technique; and

a transceiver operatively coupled to the access controller, the transceiver being configured to receive an authentication query from the refillable fuel cartridge, the authentication query being used for authenticating the refillable fuel cartridge using a first pre-specified authentication technique.

10. The electronic device as recited in claim 9, wherein the fuel container is configured to store fuel that is capable of being oxidized to produce electrical energy.

11. The electronic device as recited in claim 10, wherein the fuel container is configured to enable transfer of the fuel between the electronic device and the refillable fuel cartridge.

12. The electronic device as recited in claim 11, wherein:

the electronic device is a refilling device; and

the fuel is provided to the refillable fuel cartridge by the electronic device.

13. The electronic device as recited in claim 11, wherein:

the electronic device is a consuming device to be used in the other device; and

the fuel is received by the electronic device from the refillable fuel cartridge.

14. The electronic device as recited in claim 9, wherein the access controller is configured to:

check a status variable of the refillable fuel cartridge;

enable transfer of fuel between the fuel container and the refillable fuel cartridge when the status variable of the refillable fuel cartridge is a valid value; and

disable transfer of fuel between the fuel container and the refillable fuel cartridge when the status variable of the refillable fuel cartridge is an invalid value.

15. The electronic device as recited in claim 14, wherein the access controller is configured to discard the refillable fuel cartridge.

16. The electronic device as recited in claim 19, wherein the transceiver is configured to:

receive a status variable of the refillable fuel cartridge from the refillable fuel cartridge; and

send a request to the refillable fuel cartridge for updating the status variable of the refillable fuel cartridge.

17. The electronic device as recited in claim 9, further comprising a memory being configured to store a set of parameters required for checking a status variable of the refillable fuel cartridge.

18. The electronic device as recited in claim 9, wherein the transceiver comprises a Radio frequency Identification (RFID) reader.

19. The electronic device as recited in claim 9, wherein each of the first and second pre-specified authentication techniques is a challenge-response authentication technique.

20. A system for validating one or more refillable fuel cartridges, the system comprising:

a refillable fuel cartridge to be used with an electronic device comprising;

a first fuel container having a first compartment to store fuel that is capable of being oxidized to produce electrical energy;

a first access controller operatively coupled to the first fuel container, the first access controller being configured to authenticate a second device using a first pre-specified authentication technique; and

a first transceiver operatively coupled to the first access controller, the first transceiver being configured to receive an authentication query from the second device,

wherein the second device comprises;

a second fuel container having a second compartment to store fuel that is capable of being oxidized to produce electrical energy;

a second access controller operatively coupled to the second fuel container, the second access controller being configured to authenticate the first device using a second pre-specified authentication technique; and

a second transceiver operatively coupled to the second access controller, the second transceiver being configured to receive an authentication query from the first device.
