Abstract

Movement information describing a movement of a tracking device is received at a mobile device. The mobile device determines a location associated with the tracking device, and provides the determined location, an identity of the tracking device, and the received movement information to a tracking server. The tracking server is configured to select one or both of the determined location or a previous location of the tracking device stored by the tracking server based on the movement information. The tracking server then provides, in response to a request for location information, the selected one or both of the determined location or a previous location to a requesting entity.

Claims

1. A method comprising:

receiving, at a mobile device from a tracking device, movement information describing a movement of the tracking device;

determining, by the mobile device, a location associated with the tracking device; and

providing, by the mobile device to a tracking server, an identity of the tracking device, the determined location associated with the tracking device, and the received movement information, the tracking server configured to;

select one or both of the determined location or a previous location of the tracking device stored by the tracking server based on the movement information;

receive a request for location information from a requesting entity; and

provide the selected one or both of the determined location and the previous location to the requesting entity.

2. The method of claim 1, wherein the movement information describes a magnitude of movement of the tracking device.

3. The method of claim 1, wherein the movement information describes a direction of movement of the tracking device.

4. The method of claim 1, wherein the tracking server is configured to store the determined location in association with the identity of the tracking device.

5. The method of claim 1, wherein the tracking server is configured to select the previous location in response to a determination that the movement described by the movement information comprises less than a threshold amount of movement.

6. The method of claim 1, wherein the tracking server is configured to select the determined location in response to a determination that the movement described by the movement information comprises greater than a threshold amount of movement.

7. The method of claim 1, wherein the tracking server is configured to select one or both of the determined location or the previous location based additionally on a distance between the tracking device and the mobile device.

8. The method of claim 7, wherein the distance between the tracking device and the mobile device is determined based on a strength of a signal broadcast by the tracking device.

9. The method of claim 7, wherein the tracking server is configured to select the determined location in response to a determination that the mobile device and the tracking device are within a threshold distance of each other.

10. The method of claim 7, wherein the tracking server is configured to select the previous location in response to a determination that the mobile device and the tracking device are more than a threshold distance from each other.

11. The method of claim 1, wherein the tracking server is configured to select both the previous location and the determined location in response to a determination that a measure of accuracy describing the previous location and a measure of accuracy describing the determined location are within a threshold measure of accuracy of each other.

12. The method of claim 1, wherein the requesting entity comprises the mobile device, and wherein the mobile device is configured to present the received selected locations to a user of the mobile device.

13. The method of claim 1, wherein the mobile device is configured to provide to the tracking device a confirmation that the tracking device identity, the determined location, and the movement information were provided to the tracking server.

14. The method of claim 13, wherein tracking device is configured to enter a standby mode in response to receiving the confirmation, and wherein the tracking device is configured to stay in the standby mode until subsequent movement is detected.

15. A system comprising:

a non-transitory computer-readable storage medium storing executable computer instructions for;

receiving, from a tracking device, movement information describing a movement of the tracking device;

determining a location associated with the tracking device; and

providing, to a tracking server, an identity of the tracking device, the determined location associated with the tracking device, and the received movement information, the tracking server configured to;

select one or both of the determined location or a previous location of the tracking device stored by the tracking server based on the movement information;

receive a request for location information from a requesting entity; and

provide the selected one or both of the determined location and the previous location to the requesting entity; and

a processor configured to execute the computer instructions.

16. A non-transitory computer-readable storage medium storing executable computer instructions for:

receiving, from a tracking device, movement information describing a movement of the tracking device;

determining a location associated with the tracking device; and
