Abstract

Mobile computing systems are provided having an ultra-mobile PC and a detachable wireless communications module operable as phone and a short range and long range wireless data link. In one embodiment, the wireless communications module is capable of synchronizing data with the ultra-mobile PC. Another embodiment provides parasitic charging of the wireless communications module from the ultra-mobile PC battery for extended battery life. Another embodiment provides ability to synchronize data to and from the ultra-mobile PC even when it is powered off. Another embodiment provides drag and drop capability between the wireless module screen and the UMPC screen, which may provide application or operating system data transfers.

Claims

1. An mobile computing system comprising:

a wireless voice and data module;

a portable computer adapted to detachably connect to the wireless voice and data module, the computer adapted to supply power to the wireless voice and data module;

wherein the wireless voice and data module comprises a short range wireless transceiver and a long range wireless transceiver, the wireless voice and data module containing software instructions for synchronizing data with the computer over the short range wireless transceiver.

2. The system of claim 1 wherein the short range wireless transceiver is a Bluetooth transceiver.

3. The system of claim 1 wherein the computer is adapted to supply secondary power to the wireless voice and data module.

4. The system of claim 1 wherein the wireless voice and data module is adapted to supply power to the computer.

5. The system of claim 1 wherein the wireless voice and data module further comprises a WLAN transceiver.

6. The system of claim 1 wherein the computer is a UMPC.

7. The system of claim 1 wherein the computer comprises a touchscreen of a size optimized for mobile computing.

8. The system of claim 7 in which the screen has a diagonal length of approximately 7 inches.

9. The system of claim 7 in which the screen has a diagonal length of approximately 4 to 8 inches.

10. The system of claim 1 wherein the long range wireless transceiver is a cellular transceiver.

11. The system of claim 10 further comprising a WLAN transceiver in the wireless voice and data module.

12. The system of claim 1 wherein the long range wireless transceiver is a WLAN transceiver, the wireless voice and data module being adapted to transmit VoIP data over the WLAN transceiver.

13. The system of claim 1 wherein the computer comprises a shared-access nonvolatile storage area accessible by the mobile device when the computer is in a powered-off state.

14. An mobile computing system comprising:

a wireless voice and data module;

a portable computer adapted to detachably connect to the wireless voice and data module;

wherein the wireless voice and data module comprises a short range wireless transceiver, a long range wireless transceiver, and a data connector adapted to conductively connect to the computer, the wireless voice and data module containing a synchronization manager module adapted to synchronize data with the computer.

15. The system of claim 14 in which the synchronization manager module is further adapted to synchronize data with a third computer device through the long range wireless transceiver.

16. The system of claim 14 wherein the synchronization module is operable to synchronize in a first mode over the short range wireless transceiver or in a second mode over the data connector.

17. The system of claim 16 wherein the synchronization module is operable to synchronize in a third mode over the long range wireless connection.

18. The system of claim 14 wherein the portable computer is adapted to supply power for charging the battery of the wireless voice and data module.

19. A computer system comprising:

a computer having a nonvolatile storage and a power source;

a wakeup logic circuit coupled to the nonvolatile storage to and to the power source, the wakeup circuit operable to receive a wakeup signal from a detachable external module while the computer is powered-off, and in response to the receiving the wakeup signal, the wakeup circuit being operable to provide read and write access to the nonvolatile storage without powering on the computer.

20. The computer system of claim 19 in which the wakeup logic circuit is operable to activate only a selected portion of the nonvolatile storage when providing read and write to the nonvolatile storage.
