Abstract

A portable communications device includes a transceiver module and a cover detachably installed on the transceiver module. The cover contains magnetic media disposed on the cover, the magnetic media emitting a magnetic flux for identifying the cover. The transceiver module includes a magnetic sensor for measuring the magnetic flux emitted by the magnetic media and generating a corresponding output signal and a control circuit for receiving the output signal from the magnetic sensor and determining an identification of the cover based on the received output signal.

Claims

1. A portable communications device comprising:

a cover comprising magnetic media disposed on the cover, the magnetic media emitting a magnetic flux for identifying the cover; and

a transceiver module, the cover being detachably installed on the transceiver module, the transceiver module comprising;

a magnetic sensor for measuring the magnetic flux emitted by the magnetic media and generating a corresponding output signal; and

a control circuit for receiving the output signal from the magnetic sensor and determining an identification of the cover based on the received output signal.

2. The portable communications device of claim 1 further comprising a database stored in a memory for storing Man-Machine Interface (MMI) attributes corresponding to the identification of the cover.

3. The portable communications device of claim 1 wherein the cover comprises a front cover and a rear cover, and the magnetic media is disposed on an inner side of the front cover.

4. The portable communications device of claim 1 wherein the magnetic sensor is disposed on a printed circuit board (PCB) of the transceiver module.

5. The portable communications device of claim 1 wherein the output signal generated by the magnetic sensor is an analog output voltage.

6. The portable communications device of claim 5 wherein the magnetic sensor is a linear Hall effect sensor and the analog output voltage is directly proportional to the measured magnetic flux.

7. The portable communications device of claim 1 wherein the magnetic media is a magnet.

8. The portable communications device of claim 1 wherein the magnetic media is magnetic powder.

9. The portable communications device of claim 1 being a mobile phone.

10. A method of identifying a detachable cover of a portable communications device, the method comprising:

providing magnetic media disposed on the cover, the magnetic media emitting a magnetic flux for identifying the cover;

measuring the magnetic flux emitted by the magnetic media and generating a corresponding output signal with a magnetic sensor; and

determining an identification of the cover based on the output signal.

11. The method of claim 10 further comprising searching a database stored in a memory of the portable communications device for Man-Machine Interface (MMI) attributes corresponding to the identification of the cover and loading the MMI attributes into the portable communications device.

12. The method of claim 10 wherein the cover comprises a front cover and a rear cover, and the magnetic media is disposed on an inner side of the front cover.

13. The method of claim 10 further comprising disposing the magnetic sensor on a printed circuit board (PCB) of the transceiver module.

14. The method of claim 10 wherein the output signal generated by the magnetic sensor is an analog output voltage.

15. The method of claim 14 wherein the magnetic sensor is a linear Hall effect sensor and the analog output voltage is directly proportional to the measured magnetic flux.

16. The method of claim 10 wherein the magnetic media is a magnet.

17. The method of claim 10 wherein the magnetic media is magnetic powder.

18. The method of claim 10 wherein the portable communications device is a mobile phone.
