Abstract

A method and handheld electronic device for detecting and providing notification of a device drop are provided. In accordance with one embodiment, there is provided a method for providing notification of a device drop on an electronic device, the method comprising: receiving first data from a first sensor; monitoring second data from at least one of a second sensor or input device to detect one or more secondary indications of a device drop; and issuing an alert when the first data indicates a freefall event and the second data indicates at least one secondary indication of a device drop has been detected.

Claims

1. A method for providing notification of a device drop on an electronic device, the method comprising:

receiving first data from a first sensor;

monitoring second data from at least one of a second sensor or input device to detect one or more secondary indications of a device drop; and

issuing an alert when the first data indicates a freefall event and the second data indicates at least one secondary indication of a device drop has been detected.

2. The method of claim 1 wherein the secondary indication of a device drop is inactivity of the electronic device, the method comprising:

issuing the alert when a freefall event and after a predetermined duration of inactivity of the electronic device has elapsed.

3. The method of claim 1 wherein the secondary indication of a device drop is impact of the electronic device, the method comprising:

issuing the alert when the first data indicates a freefall event and impact of the electronic device within a predetermined duration of the freefall event.

4. The method of claim 1 wherein the secondary indication of a device drop is whether the electronic device is out of a holster, the method comprising determining whether the electronic device is out of a holster;

wherein the alert is issued when the first data indicates a freefall event and the electronic device is out of the holster.

5. The method of claim 4 wherein the alert is issued when the electronic device is out of the holster and the first data indicates freefall event within a predetermined duration of the electronic device being out of the holster.

6. The method of claim 1 wherein the secondary indication of a device drop is based on images acquired by a digital camera of the electronic device, the method comprising:

capturing a series of two or more images using a digital camera of the electronic device when the first data indicates a freefall event;

comparing the images in the series to determine a change in a reference value of the images; and

determining whether the reference value is greater than or equal to a predetermined threshold;

wherein the alert is issued when the first data indicates the freefall event and the reference value is greater than or equal to the predetermined threshold.

7. The method of claim 1 wherein the alert comprises one or any combination of a visual, audio and physical indication.

8. The method of claim 1 further comprising automatically performing a data security action within a predetermined duration of the first data indicating a freefall event.

9. The method of claim 1 wherein the issuing includes sending an electronic communication to a designated address over a wireless communication link, the electronic communication including a map of a location of the electronic device.

10. The method of claim 9 wherein the electronic communication includes the location of the electronic device.

11. The method of claim 10 further comprising:

determining the location of the electronic device; and

generating the map of the location of the electronic device using a mapping application on the electronic device.

12. The method of claim 11 further comprising generating the electronic communication to include the map and location of the electronic device.

13. The method of claim 9 wherein the alert comprises one or any combination of a visual, audio and physical indication.

14. The method of claim 9 further comprising automatically performing a data security action within a predetermined duration of the first data indicating a freefall event.

15. A portable electronic device, comprising:

a processor;

a first sensor, second sensor and input device coupled to the processor;

the processor being configured for;

receiving first data from the first sensor;

monitoring second data from at least one of the second sensor or input device to detect one or more secondary indications of a device drop; and

issuing an alert when the first data indicates a freefall event and the second data indicates at least one secondary indication of a device drop has been detected.

16. The device of claim 15 wherein the processor is configured to issue the alert when the first data indicates a freefall event and after a predetermined duration of inactivity of the electronic device has elapsed.

17. The device of claim 15 wherein the processor is configured to issue the alert when the first data indicates a freefall event and the first data indicates impact of the electronic device within a predetermined duration of the freefall event.

18. The device of claim 15 wherein the processor is configured to issue the alert when the first data indicates a freefall event and the electronic device is out of the holster.

19. The device of claim 18 wherein the alert is issued when the electronic device is out of the holster and the first data indicates a freefall event within a predetermined duration of the electronic device being out of the holster.

20. The device of claim 15 further comprising a digital camera coupled to the processor, wherein the processor is further configured to capture a series of two or more images using the digital camera when the first data indicates a freefall event, compare the images in the series to determine a change in a reference value of the images, determine whether the reference value is greater than or equal to a predetermined threshold, and issue the alert when the first data indicates a freefall event and the reference value is greater than or equal to the predetermined threshold.
