Systems and methods for managing lost devices
View Patent ↗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.
1. A device, comprising:
a component configured such that when the device learns that the device has been lost, the device produces at least one alert that includes at least one of:
a flashing of a camera flash component on the device;
a flashing of a display screen on the device;
upon the device detecting that the device is in a location with a wireless Internet connection, a transmission of a message to a target device associated with the detected location; and
upon the device detecting that the device has moved, an emission of a visible or audible signal,
wherein the device learns that the device has been lost without receiving a message indicating that the device has been lost,
wherein the device learns that the device has been lost by at least one of:
the device determining by means of a positioning system that the device has not moved for a period of time longer than a pre-specified period of time, and determining that the device is not in a 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 by means of the positioning system that the device is not in a location that is considered likely to be unoccupied;
the device detecting a sound associated with a location where the device is unlikely to be located; and
the device failing for a pre-specified length of time to detect a sound associated with a location where the device is likely to be located.
2. The device of claim 1 , wherein the device is further capable, upon learning that the device has been lost, of producing at least one further alert that includes at least one of:
a display of a message on the display screen on the device;
an emission of an audible signal; and
a production of a spoken message transmitted to the device.
3. The device of claim 2 , wherein the device produces a plurality of alerts in a pre-specified sequence, relatively less noticeable alerts occurring earlier in the sequence than relatively more noticeable alerts.
4. The device of claim 2 , wherein the device does not produce at least one of the alerts when a battery level of the device is below a pre-specified level.
5. A device, comprising:
a component configured such that when the device learns that the device has been lost, the device produces at least one alert that includes a flashing of a camera flash component on the device, wherein the device produces the flashing of the flash component without causing the camera to obtain an image,
wherein the device learns that the device has been lost without receiving a message indicating that the device has been lost,
wherein the device learns that the device has been lost by:
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 one of:
a stored location that has been designated as a location where the device is unlikely to be located, and
not a stored location that has been designated as a location where the device is likely to be located.
6. A method for a device to determine that it has been lost and to produce an alert, the method comprising:
the device determining it has been lost, wherein determining the device has been lost includes at least one of:
determining that the device has not moved for a period of time longer than a pre-specified period of time, and determining that the device is not in a 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 location that is considered likely to be unoccupied;
detecting a sound associated with a location where the device is unlikely to be located; and
failing for a pre-specified length of time to detect a sound associated with a location where the device is likely to be located, and
the device producing the alert upon determining that it has been lost, the alert including at least one of:
a flashing of a camera flash component on the device;
a flashing of a display screen on the device;
a display of a message on the display screen on the device;
an emission of an audible signal;
a production of a spoken message transmitted to the device;
upon the device detecting that the device is in a location with a wireless Internet connection, a transmission of a message to a target device associated with the detected location; and
upon the device detecting that the device has moved, an emission of a visible or audible signal,
wherein the device produces the alert without receiving a message indicating that the device has been lost.
7. The method of claim 6 , wherein the device produces a plurality of alerts in a pre-specified sequence, relatively less noticeable alerts occurring earlier in the sequence than relatively more noticeable alerts.
8. The method of claim 6 , wherein the device does not produce at least one of the alerts when a battery level of the device is below a pre-specified value.
9. A non-transitory computer readable medium storing instructions executable by a processor to implement a method, the method comprising:
a device determining it has been lost, wherein determining the device has been lost includes at least one of:
determining that the device has not moved for a period of time longer than a pre-specified period of time, and determining that the device is not in a 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 location that is considered likely to be unoccupied;
detecting a sound associated with a location where the device is unlikely to be located; and
failing for a pre-specified length of time to detect a sound associated with a location where the device is likely to be located, and
the device producing at least one alert upon determining that it has been lost, the at least one alert including at least one of:
a flashing of a camera flash component on the device;
a flashing of a display screen on the device;
upon the device detecting that the device is in a location with a wireless Internet connection, a transmission of a message to a target device associated with the detected location; and
upon the device detecting that the device has moved, an emission of a visible or audible signal,
wherein the device produces the at least one alert without having received a message indicating that the device has been lost.
