Abstract

A method for a device to determine that it has been lost is provided. The method comprises the device determining its current location, the device comparing its current location to a plurality of stored locations, and the device determining that it has been lost when its current location is a stored location that has been designated as a location where the device is unlikely to be located or is not a stored location that has been designated as a location where the device is likely to be located.

Claims

1. A device, comprising:

a camera comprising a flash component; and

a component configured such that in response to the device determining that the device has been lost, the device produces at least one alert that includes a flashing of the flash component on the device, wherein the device produces the flashing of the flash component without causing the camera to obtain an image.

2. The device of claim 1, wherein the component is further configured such that when the device detects that the device is in a first location with a light level below a first value, the device activates the at least one alert, and when the device detects that the device is in a location with a sound level below a second value, the device activates a vibration alert.

3. The device of claim 2, wherein activating the flash component comprises periodically causing the flash component or a display screen of the device to flash, and wherein activating the vibration alert comprises periodically causing the device to vibrate.

4. The device of claim 2, wherein the device deactivates the at least one alert or the vibration alert in response to one of:

the device determining that a battery level of the device is below a level, or

the device failing to detect that the device has been found within a duration.

5. The device of claim 4, wherein, when the device deactivates the at least one alert or the vibration alert, the device reactivates the at least one alert or the vibration alert in response to detecting at least one of:

a press of a button on the device;

a physical input via a touch screen display of the device;

a sound;

or

movement of the device.

6. The device of claim 5, wherein the device produces at least one further alert when the device reactivates the at least one alert or the vibration alert, the at least one further alert including at least one of:

a display of a message on a display screen of the device, the message indicating that the device is lost; and

a pre-recorded voice message through a speaker on the device, the pre-recorded message indicating that the device is lost.

7. The device of claim 1, wherein the device determines the device has been lost by at least one of:

the device determining that the device has not moved for a period of time, and determining that the device is not in a first location where a lack of movement of the device is considered likely;

the device determining by a lack of detected sound that the device is in an unoccupied location, and determining that the device is not in a second location that is considered likely to be unoccupied;

the device detecting a sound associated with a third location where the device is unlikely to be located;

or

the device failing for a length of time to detect a sound associated with a fourth location where the device is likely to be located.

8. A method implemented in a device, the method comprising:

determining that the device has been lost; and

producing at least one alert in response to determining that the device has been lost, the at least one alert including a flashing by a flash component of a camera on the device, wherein the device produces the flashing of the flash component without causing the camera to obtain an image.

9. The method of claim 8, further comprising activating the at least one alert upon detecting that the device is in a first location with a light level below a first value, and activating a vibration alert upon detecting that the device is in a location with a sound level below a second value.

10. The method of claim 9, wherein activating the at least one alert comprises periodically causing one of the flash component or a display screen of the device to flash, and wherein activating the vibration alert comprises periodically causing the device to vibrate.

11. The method of claim 10, wherein the device deactivates the at least one alert or the vibration alert in response to at least one of:

determining that a battery level of the device is below a level, or

failing to detect that the device has been found within a duration.

12. The method of claim 11, wherein, when the device deactivates the at least one alert or the vibration alert, the device reactivates the at least one alert or the vibration alert in response to detecting at least one of:

a press of a button on the device;

a physical input via a touch screen display of the device;

a sound;

or

movement of the device.

13. The method of claim 12, further comprising producing at least one further alert when reactivating the at least one alert or the vibration alert, wherein producing the at least one further alert includes at least one of:

displaying a message on the display screen of the device, the message indicating that the device is lost;

or

outputting a pre-recorded voice message through a speaker on the device, the pre-recorded message indicating that the device is lost.

14. The method of claim 8, wherein determining that the device has been lost comprises at least one of:

determining that the device has not moved for a period of time, and determining that the device is not in a first location where a lack of movement of the device is considered likely;

determining by a lack of detected sound that the device is in an unoccupied location, and determining that the device is not in a second location that is considered likely to be unoccupied;

detecting a sound associated with a third location where the device is unlikely to be located;

or

failing for a length of time to detect a sound associated with a fourth location where the device is likely to be located.

15. A non-transitory computer readable medium storing instructions executable by a processor to implement a method in a device, the method comprising:

determining that the device has been lost; and

producing at least one alert in response to determining that the device has been lost, the at least one alert including a flashing by a flash component of a camera on the device, wherein the device produces the flashing of the flash component without causing the camera to obtain an image.

16. The non-transitory computer readable medium of claim 15, wherein the method further comprises activating an at least one alert upon detecting that the device is in a first location with a light level below a first value, and activating a vibration alert upon detecting that the device is in a location with a sound level below a second value.

17. The non-transitory computer readable medium of claim 16, wherein activating the at least one alert causes at least one of the flash component or a display screen of the device to periodically flash, and wherein activating the vibration alert causes the device to vibrate.

18. The non-transitory computer readable medium of claim 17, wherein the method further comprises deactivating the at least one alert or the vibration alert in response to at least one of:

determining that a battery level of the device is below a level, or

failing to detect that the device has been found within a duration.

19. The non-transitory computer readable medium of claim 18, wherein, when the device deactivates the at least one alert or the vibration alert, the device reactivates the at least one alert or the vibration alert in response to detecting at least one of:

a press of a button on the device;

a physical input via a touch screen display of the device;

a sound;

or

movement of the device.

20. The non-transitory computer readable medium of claim 15, wherein determining that the device has been lost comprises at least one of:

determining that the device has not moved for a period of time, and determining that the device is not in a first location where a lack of movement of the device is considered likely;

determining by a lack of detected sound that the device is in an unoccupied location, and determining that the device is not in a second location that is considered likely to be unoccupied;

detecting a sound associated with a third location where the device is unlikely to be located; and

failing for a length of time to detect a sound associated with a fourth location where the device is likely to be located.
