Abstract

A cellular phone includes a housing and a cover detachably installed on the housing, the cover containing an ID module for identifying the cover. The cellular phone also contains a transceiver for controlling operation of the cellular phone, the transceiver containing a detection port for communicating with the ID module of the cover and determining identification of the cover, a memory electrically connected to the transceiver, and a database stored in the memory for providing operation parameters to the transceiver according to the identification of the cover.

Claims

1. A cellular phone comprising:

a housing;

a cover detachably installed on the housing, the cover containing an ID module for identifying the cover;

a transceiver for controlling operation of the cellular phone, the transceiver containing a detection port for communicating with the ID module of the cover and determining identification of the cover;

a memory electrically connected to the transceiver; and

a database stored in the memory for providing operation parameters to the transceiver according to the identification of the cover.

2. The cellular phone of claim 1 wherein the database includes an acoustic database, the acoustic database providing Finite Impulse Response (FIR) filter coefficients to the transceiver for improving acoustics of the cellular phone.

3. The cellular phone of claim 1 wherein the database includes a power amplification database, the power amplification database providing voltage compensation coefficients to the transceiver for improving power amplification of the cellular phone.

4. The cellular phone of claim 1 wherein the database includes a Man-Machine Interface (MMI) database, the MMI database providing user interface attributes to the transceiver according to the identification of the cover.

5. The cellular phone of claim 4 wherein the MMI database contains a keypad-mapping configuration corresponding to each cover.

6. The cellular phone of claim 4 wherein the MMI database contains a set of sound files corresponding to each cover.

7. The cellular phone of claim 4 wherein the MMI database contains a set of graphical images corresponding to each cover.

8. The cellular phone of claim 4 wherein the MMI database contains a Light Emitting Diode (LED) configuration corresponding to each cover.

9. The cellular phone of claim 1 wherein the ID module of the cover contains a unique resistance value for identifying the cover, and the transceiver measures the resistance for determining the identification of the cover.

10. The cellular phone of claim 1 wherein the detection port of the transceiver is capable of communicating with the ID module of the cover in parallel for determining the identification of the cover.

11. A method of identifying a detachable cover of a cellular phone, the cellular phone comprising a housing, the method comprising:

providing an ID module on the cover for identifying the cover;

providing a transceiver for controlling operation of the cellular phone, the transceiver containing a detection port for communicating with the ID module of the cover and determining identification of the cover; and

identifying the cover with the detection port.

12. The method of claim 11 further comprising searching a database stored in memory for providing operation parameters and attributes to the transceiver according to the identification of the cover.

13. The method of claim 12 wherein the database includes an acoustic database, and the method further comprises searching the acoustic database for providing Finite Impulse Response (FIR) filter coefficients to the transceiver for improving acoustics of the cellular phone.

14. The method of claim 12 wherein the database includes a power amplification database, and the method further comprises searching the power amplification database for providing voltage compensation coefficients to the transceiver for improving power amplification of the cellular phone.

15. The method of claim 12 wherein the database includes a Man-Machine Interface (MMI) database, and the method further comprises searching the MMI database for providing user interface attributes to the transceiver according to the identification of the cover.

16. The method of claim 15 wherein the MMI database contains a keypad-mapping configuration corresponding to each cover.

17. The method of claim 15 wherein the MMI database contains a set of sound files corresponding to each cover.

18. The method of claim 15 wherein the MMI database contains a set of graphical images and a Light Emitting Diode (LED) configuration corresponding to each cover.

19. The method of claim 11 wherein the ID module of the cover contains a unique resistance value for identifying the cover, and the transceiver measures the resistance for determining the identification of the cover.

20. The method of claim 11 wherein the detection port of the transceiver is capable of communicating with the ID module of the cover in parallel for determining the identification of the cover.
