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.

Abstract: A tracking system determines that a first device of an owner of a tracking device is not within a proximity of the tracking device, that a second device is within a proximity of the tracking device, and whether a tracking application is not running on the first device. Responsive to determining that the tracking application is not running on the first device, the tracking system generates a notification informing the owner that the tracking application is not running on the first device. Responsive to determining that a location of the second device within a proximity of the tracking device is more than a threshold distance from a last known location of the tracking device, the tracking system generates a another notification informing the owner that the tracking device may be lost. The tracking system provides one or both of the notifications to the first device for display to the owner.

Abstract: An online system receives one or more aggregation rules associated with a third party system that determine online system users' eligibility for receiving content items provided by the third party system using the online system users' behavior. When an online system user performs actions related to content provided by the third party system via a client device, events describing the actions are generated and communicated from the client device to the online system. The online system evaluates a user's eligibility when a user performs an action by applying an aggregation rule to an event corresponding to the user's action and other events associated with the user corresponding to the user's previous actions. The online system may re-evaluate a user's eligibility at a later time if the user is determined to be ineligible. The online system provides content items to eligible users for presentation.

Abstract: A tracking device can be configured into a “lost” operating mode in response to a physical trigger that does not require communication with a tracking system of the tracking device. The tracking device periodically transmits identification information to nearby mobile devices that relay the information to the tracking system. However, a user that is not able to communicate with the tracking system can interact with a physical input of the tracking device. In response to the interaction, the tracking device configures itself to operate in the lost mode. When configured in the lost mode, the tracking device can increase the frequency at which it transmits beacon signals with its identification information. Additionally, when the tracking device is configured in the lost mode, it includes a lost indicator in its transmissions, so that devices that receive its transmissions are able to notify the tracking system that the tracking device is lost.

Abstract: A lost tracking device associated with a tracking system can be located by leveraging one or more community members by inviting these members to join a search party. Search party criteria can be identified and candidate search party members can be selected and invited based on the search party criteria. When invited candidate search party members accept the invitations, they are added to the search party. A last known location of the tracking device can be provided to the search party members, and the search party can remain in effect until the lost tracking device is located. The location of the lost tracking device is provided to the tracking system, which forwards it to the owner of the lost tracking device. A reward can be provided by the owner of the lost tracking device to the tracking system, which releases the reward to the search party member that located the lost tracking device.
