Abstract

A tracking system can provide intervention notifications to a user to notify the user that a tracking device is potentially lost or is in a predicted state. The tracking system may notify the user that a tracking device is potentially lost or in a predicted state based on a number of factors, including: a proximity of a tracking device to other tracking devices or a user'"'"'s mobile device, a movement of a tracking device to more than a threshold distance away from a mobile device or other tracking devices, a location of a tracking device relative to a geographic location or to geographic boundaries, a usage or movement behavior of the tracking device, a usage or movement behavior of a user or owner of a tracking device, information received from an external source, or information received from sensors within the tracking device or a user'"'"'s mobile.

Claims

1. A method for locating a tracking device, comprising:

receiving, at a central tracking device system, a first location of a first tracking device of a first user from a first mobile device in response to the first mobile device detecting the first tracking device while in a communicative range of the first tracking device;

receiving, at the central tracking device system, a second location of a second tracking device of the first user from a second mobile device different than the first mobile device in response to the second mobile device detecting the second tracking device while in a communicative range of the second tracking device;

determining a distance between the first location and the second location;

in response to the determined distance being greater than a threshold distance, identifying, by the central tracking device system, the first tracking device as potentially lost;

generating, by the central tracking device system, a notification identifying the first tracking device and indicating the first tracking device is potentially lost; and

providing, by the central tracking device system, the generated notification to a mobile device of the first user, the mobile device of the first user configured to display the notification to the first user.

2. The method of claim 1, wherein the first mobile device communicatively couples to the first tracking device and, in response to communicatively coupling to the first tracking device, determines a location of the first mobile device using a location-detection apparatus and provides the determined location to the central tracking device system in association with an identity of the first tracking device.

3. The method of claim 1, further comprising receiving, at the central tracking device system, a definition of a group of tracking devices including the first tracking device and the second tracking device.

4. The method of claim 3, wherein the identification of the first tracking device as potentially lost is in response to the first tracking device not being located within the threshold distance of locations of each tracking device in the group of tracking devices.

5. The method of claim 1, further comprising receiving the threshold distance from the first user.

6. The method of claim 1, wherein determining that the first location is more than a threshold distance away from the second location comprises determining that the second tracking device is not within a communicative range of the first mobile device.

7. The method of claim 1, wherein the identification of the first tracking device as potentially lost is in response to determining the determined distance is greater than a threshold distance during a pre-determined time period.

8. The method of claim 7, wherein the pre-determined time period is one of a time period selected by the first user or a time period corresponding to a historical time period during which the first tracking device and the second tracking device were located within the threshold distance of each other.

9. A non-transitory computer-readable storage medium storing executable computer program instructions for locating a tracking device, the computer program instructions comprising instructions that, when executed by a processor of the central tracking device system, cause the central tracking device system to:

receive a first location of a first tracking device of a first user from a first mobile device in response to the first mobile device detecting the first tracking device while in a communicative range of the first tracking device;

receive a second location of a second tracking device of the first user from a second mobile device different than the first mobile device in response to the second mobile device detecting the second tracking device while in a communicative range of the second tracking device;

determine a distance between the first location and the second location;

in response to the determined distance being greater than a threshold distance, identify the first tracking device as potentially lost;

generate a notification identifying the first tracking device and indicating the first tracking device is potentially lost; and

provide the generated notification to a mobile device of the first user, the mobile device of the first user configured to display the notification to the first user.

10. The computer-readable medium of claim 9, wherein the first mobile device communicatively couples to the first tracking device and, in response to communicatively coupling to the first tracking device, determines a location of the first mobile device using a location-detection apparatus, and provides the determined location to the central tracking device system in association with an identity of the first tracking device.

11. The computer-readable medium of claim 9, wherein the instructions further cause the central tracking device system to receive the threshold distance from the first user.

12. The computer-readable medium of claim 9, wherein the instructions for identifying the first tracking device as potentially lost are executed in response to determining that the first location is more than a threshold distance away from the second location during a pre-determined time period.

13. The computer-readable medium of claim 12, wherein the pre-determined time period is one of a time period selected by the first user or a time period corresponding to a historical time period during which the first tracking device and the second tracking device were located within the threshold distance of each other.

14. The computer-readable medium of claim 9, wherein the instructions further cause the processor to receive a definition of a group of tracking devices including the first tracking device and the second tracking device.

15. The computer-readable medium of claim 14, wherein the identification of the first tracking device as potentially lost is in response to the first tracking device not being located within the threshold distance of locations of each tracking device in the group of tracking devices.
