Abstract

Technology for an electronic device is described. The electronic device can include a fingerprint sensor, a heart rate sensor, and a controller. The controller can receive a fingerprint of a user captured using the fingerprint sensor. The controller can determine whether the fingerprint of the user matches a predefined fingerprint stored in a data store of the electronic device. The controller can receive heart rate information of the user captured using the heart rate sensor. The controller can determine whether the heart rate information is within a defined range. The controller can unlock the electronic device to allow the user to access the electronic device when the fingerprint of the user matches the predefined fingerprint stored in the data store and the heart rate information is within the defined range.

First claim

What is claimed is:

1 . A controller in an electronic device, the controller comprising logic to:
receive a fingerprint of a user; determine whether the fingerprint of the user matches a predefined fingerprint stored in a data store; receive heart rate information of the user; determine whether the heart rate information is within a defined range; and provide access to the electronic device for the user when the fingerprint of the user matches the predefined fingerprint stored in the data store and the heart rate information is within the defined range.

2 . The controller of claim 1 , wherein the logic is configured to determine that the user is conscious when the heart rate information is within the defined range.

3 . The controller of claim 1 , wherein the logic is configured to determine that the heart rate information is within the defined range when a heart rate or a heart rate interval of the user included within the heart rate information is within the defined range.

4 . The controller of claim 1 , wherein the logic is configured to:
receive heart rate information of the user during an initial calibration period, wherein the heart rate information includes a reference heart rate or heart rate interval of the user when the user is conscious; and determine that the heart rate information indicates that the user is conscious when a heart rate or a heart rate interval included in the heart rate information corresponds to the reference heart rate or heart rate interval of the user when the user is conscious.

5 . The controller of claim 1 , wherein the logic is configured to determine to not provide the access to the electronic device for the user when the fingerprint of the user does not match the predefined fingerprint stored in the data store or the heart rate information is not within the defined range.

6 . The controller of claim 5 , wherein the logic is configured to:
cause the electronic device to provide an audio or vibratory notification when the access to the electronic device is not provided for the user; or provide a textual notification for display that indicates an attempt to access the electronic device has been denied.

7 . The controller of claim 1 , wherein the logic is configured to determine to not provide the access to the electronic device for the user when no heart rate information is received.

8 . The controller of claim 1 , wherein the logic is configured to receive updated heart rate information of the user during a recalibration period, wherein the updated heart rate information includes an updated reference heart rate or heart rate interval of the user when the user is conscious.

9 . The controller of claim 1 , wherein the logic is configured to receive the fingerprint of the user from a fingerprint sensor.

10 . The controller of claim 1 , wherein the logic is configured to receive the heart rate information from a heart rate sensor.

11 . The controller of claim 1 , wherein the controller is integrated with an electronic device, and the access provided to the user enables the user to access the electronic device.

12 . An electronic device, comprising:
a fingerprint sensor; a heart rate sensor; and logic communicatively coupled to the fingerprint sensor and the heart rate sensor, the logic configured to: receive a fingerprint of a user captured using the fingerprint sensor; determine whether the fingerprint of the user matches a predefined fingerprint stored in a data store of the electronic device; receive heart rate information of the user captured using the heart rate sensor; determine whether the heart rate information is within a defined range; and unlock the electronic device to allow the user to access the electronic device when the fingerprint of the user matches the predefined fingerprint stored in the data store and the heart rate information is within the defined range.

13 . The electronic device of claim 12 , wherein the logic is configured to determine that the user is conscious when the heart rate information is within the defined range.

14 . The electronic device of claim 12 , wherein the logic is configured to determine that the heart rate information is within the defined range when a heart rate or a heart rate interval of the user included within the heart rate information is within the defined range.

15 . The electronic device of claim 12 , wherein the logic is configured to:
receive heart rate information of the user during an initial calibration of the electronic device, wherein the heart rate information includes a reference heart rate or heart rate interval of the user when the user is conscious; and determine that the heart rate information indicates that the user is conscious when a heart rate or a heart rate interval included in the heart rate information corresponds to the reference heart rate or heart rate interval of the user when the user is conscious.

16 . The electronic device of claim 12 , wherein the logic is configured to keep the electronic device locked to prevent the user from accessing the electronic device when the fingerprint of the user does not match the predefined fingerprint stored in the data store or the heart rate information is not within the defined range, thereby indicating that the user is not conscious.

17 . The electronic device of claim 16 , wherein the logic is configured to:
provide an audio or vibratory notification when the access to the electronic device is not provided for the user; or provide a textual notification for display that indicates an attempt to access the electronic device has been denied.

18 . The electronic device of claim 12 , wherein the logic is configured to keep the electronic device locked to prevent the user from accessing the electronic device when no heart rate information is received.

19 . The electronic device of claim 12 , wherein the logic is configured to receive updated heart rate information of the user during a recalibration period, wherein the updated heart rate information includes an updated reference heart rate or heart rate interval of the user when the user is conscious.

20 . The electronic device of claim 12 , wherein the heart rate sensor includes an infrared light emitting diode (LED) and a photo diode to detect the heart rate information of the user.

21 . A system, comprising:
a data store; a fingerprint sensor; a heart rate sensor; an electronic device; and a controller, comprising logic to:
receive a fingerprint of a user captured using the fingerprint sensor;
determine whether the fingerprint of the user matches a predefined fingerprint stored in the data store;
receive heart rate information of the user captured using the heart rate sensor;
determine whether the heart rate information is within a defined range; and
unlock the electronic device to allow the user to access the electronic device when the fingerprint of the user matches the predefined fingerprint stored in the data store and the heart rate information is within the defined range.

22 . The system of claim 21 , wherein the controller comprises logic to determine that the user is conscious when the heart rate information is within the defined range.

23 . The system of claim 21 , wherein the controller comprises logic to determine that the heart rate information is within the defined range when a heart rate or a heart rate interval of the user included within the heart rate inform
