Abstract

A key integrates with a biometric input device. According to an aspect of the present disclosure, a fingerprint scanner may be integral with a spacebar.

First claim

What is claimed is:

1. A mobile communication device comprising:
an input device including:
a key; and
a biometric input device integral with said key; and

a processor adapted to:
receive first input from said input device;
determine that said first input comprises a candidate biometric from said biometric input device and then:
determine that said mobile communication device is locked;
responsive to determining that said mobile communication device is locked, process said candidate biometric;

receive second input from said key;
determine that said second input does not comprise candidate biometric; and
determine that said second input comprises an indication of a depression event from said key.

2. The mobile communication device of claim 1 wherein said key comprises a spacebar.

3. The mobile communication device of claim 1 wherein said biometric input device comprises a fingerprint scanner.

4. The mobile communication device of claim 1 wherein said key comprises a key top and a key plunger.

5. The mobile communication device of claim 4 wherein said biometric input device comprises a scanner, a flex board and a flex connector for connecting said scanner and said flex board to a mobile communication device main circuit board.

6. The mobile communication device of claim 5 wherein said scanner is mounted flush with an exposed surface of said key top.

7. The mobile communication device of claim 1 wherein said processor is further adapted to:
determine that said mobile communication device is locked; and
responsive to determining that said mobile communication device is locked, ignore said indication of said depression event.

8. A method of handling input from a key of a mobile communication device, said method comprising:
receiving first input from a key;
determining that said first input comprises a candidate biometric from a biometric input device integral with said key and then:
determining that said mobile communication device is locked;
responsive to determining that said mobile communication device is locked, processing said candidate biometric;

receiving second input from said key;
determining that said second input does not comprise candidate biometric;
determining that said second input comprises an indication of a depression event from said key.

9. The method of claim 8 further comprising storing, on the mobile communication device, a policy specifying requirements for unlocking the mobile communication device.

10. The method of claim 8 wherein processing said candidate biometric comprises comparing a stored biometric template to said candidate fingerprint.

11. The method of claim 10 further comprising:
determining that said candidate biometric does not match said stored biometric template;
incrementing a count of unsuccessful scans;
determining that said count of unsuccessful scans exceeds a threshold; and
responsive to said determining that said count of unsuccessful scans exceeds a threshold, erasing a memory of said mobile communication device.

12. The method of claim 8 further comprising:
determining that said mobile communication device is locked; and
responsive to determining that said mobile communication device is locked, ignoring said indication of said depression event.

13. A non-transitory computer-readable medium containing computer-executable instructions that, when performed by a processor in an electronic device, cause the processor to:
receive first input from a key;
determine that said first input comprises a candidate biometric from a biometric input device integral with said key and then:
determine that said mobile communication device is locked;
responsive to determining that said mobile communication device is locked, process said candidate biometric;

receive second input from said key;
determine that said second input does not comprise candidate biometric;
determine that said second input comprises an indication of a depression event from said key.

14. The non-transitory computer-readable medium of claim 13 wherein the instructions further cause the processor to:
determine that said mobile communication device is locked; and
responsive to determining that said mobile communication device is locked, ignore said indication of said depression event.

15. A mobile communication device comprising:
an input device including:
a key; and
a biometric input device integral with said key; and

a processor adapted to:
receive first input from said key;
determine that said first input comprises a candidate biometric from the biometric input device and then:
determine that said mobile communication device is unlocked;
responsive to determining that said mobile communication device is unlocked, ignore said candidate biometric;

receive second input from said key;
determine that said second input does not comprise candidate biometric;
determine that said second input comprises an indication of a depression event from said key and then:
determine that said mobile communication device is unlocked; and
responsive to determining that said mobile communication device is unlocked, process said indication of said depression event.

16. The mobile communication device of claim 15 wherein said key comprises a spacebar.

17. The mobile communication device of claim 15 wherein said biometric input device comprises a fingerprint scanner.

18. The mobile communication device of claim 15 wherein said key comprises a key top and a key plunger.

19. The mobile communication device of claim 18 wherein said biometric input device comprises a scanner, a flex board and a flex connector for connecting said scanner and said flex board to a mobile communication device main circuit board.

20. The mobile communication device of claim 19 wherein said scanner is mounted flush with an exposed surface of said key top.

21. A method of handling input from a key of a mobile communication device, said method comprising:
receiving first input from a key;
determining that said first input comprises a candidate biometric from a biometric input device integral with said key and then:
determining that said mobile communication device is unlocked;
responsive to determining that said mobile communication device is unlocked, ignoring said candidate biometric;

receiving second input from said key;
determining that said second input does not comprise candidate biometric;
determining that said second input comprises an indication of a depression event from said key and then:
determining that said mobile communication device is unlocked;
responsive to determining that said mobile communication device is unlocked, processing said indication of said depression event.

22. The method of claim 21 wherein said processing said indication of said depression event further comprises arranging insertion of a space character in a document being edited.

23. The method of claim 21 further comprising:
receiving an indication of a locking trigger event; and
responsive to said receiving said indication, locking said mobile communication device.

24. The method of claim 23 wherein said indication of said locking trigger event comprises an indication that said mobile communication device has entered a protective covering.

25. The method of claim 21 further comprising storing, on the mobile communication device, a policy specifying requirements fo
