Abstract

A wireless communication device comprises a first housing detachably connected to a second housing in a first orientation and a second orientation. An electrical connector connects circuitry in the first and second housings regardless of whether the first and second housings are joined together in the first orientation or in the second orientation. A wireless interface connects the circuitry in the first and second housings when the first and second housings are separated.

Claims

a first housing section detachably connected to a second housing section such that the second housing section can be connected to the first housing section in a first orientation and a second orientation;

the first and second housing sections being movable between first and second positions in both the first and second orientations;

an electrical interface configured to operatively connect circuits in the first and second housing sections when the first and second housing sections are joined together in both the first and second orientations; and

a wireless interface configured to operatively connect the circuits in the first and second housings sections when the first and second housing sections are separated.

2. The wireless communication device of claim 1 wherein the first housing section comprises radio frequency (RF) circuitry configured to transmit signals to and receive signals from a wireless communication network.

3. The wireless communication device of claim 2 wherein the second housing section comprises baseband circuitry configured to process the signals transmitted to and received from the wireless communication network.

4. The wireless communication device of claim 1 wherein the second housing section comprises a main display disposed on one side of the second housing section, and a sub-display disposed on an opposite side of the second housing section.

5. The wireless communication device of claim 1 wherein the electrical interface comprises a pair of corresponding connectors disposed on each of the first and second housing sections that couple when the first and second housing sections are joined together.

6. The wireless communication device of claim 5 wherein each of the first and second housing sections comprises a short-range transceiver and wherein the wireless interface comprises a short-range communication link established between the short-range transceivers.

7. The wireless communication device of claim 1 wherein the second housing section comprises a controller configured to determine whether the first and second housing sections are joined together.

8. The wireless communication device of claim 7 wherein the controller is configured to deactivate the wireless interface when the first and second housing sections are joined together, and activate the wireless interface when the first and second housing sections are separated.

9. The wireless communication device of claim 7 further comprising a microphone in each of the first and second housing sections, and wherein the controller is configured to:

activate the microphone in the first housing section when the first and second housing sections are joined together; and

activate the microphone in the second housing section when the first and second housing sections are separated.

10. The wireless communication device of claim 1 further comprising:

a power source in each of the first and second housing sections; and

a charging circuit in the first housing section configured to recharge the power source in the second housing section when the first and second housing sections are joined together.

11. The wireless communication device of claim 1 further comprising a coupling mechanism configured to couple the second housing to the first housing in the first and second orientations.

12. A method of communicating with a wireless communication device, the method comprising:

detachably connecting a first housing section to a second housing section such that the second housing section can be connected to the first housing section in first and second orientations;

movably connecting the first and second housing sections such that the first and second housing sections move between first and second positions in both the first and second orientations;

electrically connecting circuits in the first and second housing sections when the first and second housing sections are joined together in the first and second orientations; and

wirelessly connecting the circuits in the first and second housings sections when the first and second housing sections are separated.

13. The method of claim 12 further comprising transmitting signals to and receiving signals from a wireless communication network using radio frequency (RF) circuitry disposed in the first housing section.

14. The method of claim 13 further comprising processing the transmitted and received signals using baseband circuitry disposed in the second housing section.

15. The method of claim 12 wherein detachably connecting the first and second housing sections comprises releasably joining the first and second housing sections together in the first orientation such that a main display disposed on the second housing section faces towards a user of the wireless communication device.

16. The method of claim 15 wherein detachably connecting the first and second housing sections comprises releasably joining the first and second housing sections together in the second orientation such that the main display faces away from the user of the wireless communication device.

17. The method of claim 12 wherein electrically connecting circuits in the first and second housing sections comprises mating a connector on one of the first and second housing sections with a corresponding connector disposed on the other of the first and second housing sections.

18. The method of claim 17 wherein electrically connecting circuits in the first and second housing sections further comprises monitoring a signal to determine whether the first and second housing sections are joined together.

19. The method of claim 17 wherein electrically connecting circuits in the first and second housing sections further comprises deactivating the wireless interface when the first and second housing sections are joined together.

20. The method of claim 19 wherein wirelessly connecting the circuits in the first and second housings sections comprises activating a short-range communication link established between the first and second housing sections.

21. The method of claim 12 further comprising charging a battery disposed within the second housing section using a charging circuit disposed within the first housing section when the first and second housing sections are joined together.

22. A wireless communication device comprising:

a first display and a second display disposed on opposite sides of the second housing section;

one or more communication interfaces for operatively connecting the first and second displays to circuitry in the first housing section both when the first and second housing sections are joined, and when the first and second housing sections are separated.

23. The wireless communication device of claim 22 wherein the second housing section can connect to the first housing section in a first orientation and a second orientation.

24. The wireless communication device of claim 23 wherein each of the first and second housing sections comprise a connector that electrically connects the first and second displays to the first housing section when the first and second housing sections are joined in both the first and second orientations.

25. The wireless communication device of claim 24 wherein each of the first and second housing sections further comprise a short-range transceiver that wirelessly connects the first and second displays to the first housing section when the first and second housing sections are separated.

26. The wireless communication device of claim 23 wherein the first and housing sections are movably connected in both the first and second orientations.

27. A method of communicating using a wireless communication device, the method comprising:
