Abstract: A tracking device can provide a hashed identifier to a mobile device, for instance within an advertisement packet. The mobile device can query each of a plurality of entities with the hashed identifier to identify an entity associated with the hash key used to generate the hashed identifier. In some embodiments, the mobile device can query a centralized key server, which in turn can query the plurality of entities to identify the entity associated with the hash key. The mobile device can then receive a public key from the identified entity, can determine a location of the mobile device, and can encrypt the location with the public key. The mobile device can then provide the hashed identifier and the encrypted location to the identified entity, which can provide the encrypted location to an owner of the tracking device for decryption using a private key corresponding to the public key.

Abstract: Power can be preserved in a tracking device equipped with a GPS receiver and a transceiver by evaluating the proximity of the tracking device to a mobile device and enabling the GPS receiver and transceiver only in the event that the tracking device is out of the range of the mobile device. Once enabled, the location of the tracking device can be determined based on location information received from the GPS receiver. The determined location can be provided to a tracking system associated with the tracking device. The tracking system can then inform an owner of the tracking device of the determined location. Once the tracking device has been found, the GPS receiver and the transceiver can be disabled to save additional power.

Abstract: A tracking device uses user-guided trilateration to determine a current location of the tracking device. The tracking device receives a request to locate the tracking device from a user of a mobile device communicatively connected to the tracking device. The tracking device receives a series of locations of the mobile device and corresponding distances between the mobile device and the tracking device at each of the locations. The tracking device provides instructions to the user of the mobile device to move to each of the series of locations to collect location and distance data. The tracking devices performs a trilateration operation on the series of locations and corresponding distances to determine a location of the tracking device and provides the determined location to the mobile device for display.

Abstract: In one embodiment, a method includes receiving, by a tracking system server from a first computing device in response to an event between the first computing device and a tracking device, a location associated with the tracking device and a timestamp. The method includes receiving, by the tracking system server, a set of location updates from a set of second computing devices, each location update including a location associated with the tracking device when the second computing device detects the tracking device and a timestamp. The method includes determining, by the tracking system server, a last known location of the tracking device based on the location associated with the tracking device received from the first computing device and one or more of the locations associated with the tracking device received with the location update.

Abstract: A tracking device has a first transceiver, a second transceiver, and control logic. The first transceiver can transmit a first tracking signal for locating the tracking device to mobile devices via a first network. The mobile devices provide the first tracking signal to a tracking server. The second transceiver can transmit a second tracking signal for locating the tracking device to the tracking server via a second network. The control logic can configure the tracking device in a first state in which the first transceiver transmits the first tracking signal, and the second transceiver is disabled and does not transmit the second tracking signal. In response to determining that the tracking device cannot connect to the tracking server via the first network, the control logic configures the tracking device in a second state in which the second transceiver is enabled and transmits the second tracking signal.

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: In one embodiment, a method includes receiving, by a tracking server from a first computing device of multiple computing devices, a request to establish a search party to locate a tracking device associated with the tracking server. The search party includes a subset of the computing devices. The method includes selecting, by the tracking server based on the request, one or more criteria for selecting one or more second computing devices for inclusion in the search party. Each criteria defines a requirement for a candidate second computing device. The method includes identifying, by the tracking server, one or more candidate second computing devices, each candidate second computing device satisfying the requirement of each of the selected criteria. The method includes requesting, by the tracking server, the one or more candidate second computing devices to join the search party.

Abstract: An electronic device with a primary functionality and a tracking functionality can be used in a centralized tracking system. A controller configures the electronic device to operate in one of a set of: an “on” mode, an “off” mode, a first standby mode, and a tracking standby mode. While configured to operate in the “on” mode, the primary and tracking functionality of the electronic device are enabled, and while configured to operate in the “off” mode, both are disabled. While configured to operate in the first standby mode, the tracking functionality is enabled and the primary functionality is limited. While configured to operate in the tracking standby mode, the primary functionality is disabled but the tracking functionality is enabled, enabling the electronic device to be located while the primary functionality is disabled and saving power relative to the first standby mode and the “on” mode.

Abstract: A tracking system determines if a tracking device is located within a safe zone based on whether a set of safe conditions are satisfied. The set of safe conditions includes a geographic boundary or a geographic location and corresponding threshold distance. The set of safe conditions can also include a time window during which a safe zone is active. When a tracking device is within a safe zone (e.g., geographically and temporally), the tracking device is determined to be safe, and notifications associated with the tracking device can be minimized. The safe zones may be user-selected, user-defined, or determined based on data analytics. If a set of safe conditions are not satisfied, the tracking system generates and sends a notification to the user of the tracking device indicating that the tracking device may be lost.

Abstract: An electronic device can be commissioned with an identifier for use in a centralized tracking system. The electronic device is assigned an interim unique identifier and authentication key, for instance by a manufacturer of the electronic device. The electronic device and the centralized tracking system each separately generate a permanent unique identifier and a permanent authentication key based on the interim unique identifier and interim authentication key, without requiring the permanent unique identifier and permanent authentication key from being transmitted between the electronic device and the central tracking server. Upon generating the permanent unique identifier and permanent authentication key, tracking device functionality can be enabled within the electronic device, enabling the electronic device to function as a tracking device within the centralized tracking system.

Abstract: A tracking device can securely communicate with a secondary device. The secondary device can provide locations associated with the tracking device to a tracking system. When the secondary device determines that the tracking device is lost (for instance, in response to no longer receiving communications from the tracking device), the secondary device can provide additional locations associated with the secondary device to the tracking system. The tracking system can store locations received before and after the tracking device was lost, and can provide these locations to the user for display within a map interface, enabling a user to digitally retrace the user's steps in order to aid the user in locating the lost tracking device.

Abstract: The principles described herein provide methods and systems for locating a tracking device. In particular, one disclosed method includes associating a user with a tracking device, receiving an indication that the tracking device is lost, setting a flag indicating that the tracking device is lost, receiving a location within a proximity of the tracking device from one of a plurality of mobile devices associated with a community of users, and providing the location to the user.

Abstract: A tracking system can provide configuration instructions to an electronic device based on user presence. The tracking system can determine a user's location relative to a geographic boundary surrounding a geographic area associated with the user. Depending on the user's location, the tracking system may send instructions to configure an electronic device to send a notification or change the operating mode of the electronic device in response to the user's presence. The electronic device may be a scanning device that is configured to have a higher or lower scanning frequency, depending on the presence or absence of the user relative to the scanning device.

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: Tracking devices can be associated with safe zones, smart zones, and high risk zones. Safe zones correspond to regions where a likelihood that a tracking device is lost within the safe zone is lower than outside the safe zone. High risk zones correspond to regions where a likelihood that a tracking device is lost within the high risk zone is higher than outside the high risk zone. Smart zones correspond to an expected tracking device, mobile device, or user behavior. Home areas are geographic regions in which a user resides, and travel areas are geographic regions in which a user does not reside. A tracking device can be configured to operate in a mode selected based on a presence of the tracking device within a safe zone, a smart zone, a high risk zone, a home area, or a travel area.

Abstract: A tracking system determines a location of a tracking device associated with a user using one or more access points at the location. Each access point at the location is configured to detect and couple with the tracking device when the tracking device is within a communicative range of the access point. An access point provides updates on the tracking device's presence, as well as the tracking device's arrival to and departure from the communicative range of the access point, to a tracking server. The tracking server determines, from these updates, whether the tracking device is at the location. The user may be notified, via a mobile device, of the tracking device's location.

Abstract: A tracking device broadcasts beacon signals that are separated in time by broadcast intervals. The tracking device determines the broadcast intervals based on a behavior model. The behavior model specifies one or more conditions, such as times of day within a 24-hour day, and associates a usage probability with each condition. A higher usage probability causes the tracking device to broadcast beacon signals at shorter broadcast intervals. A mobile device in communication with the tracking device can reconfigure the behavior model, either by modifying portions of the behavior model or by replacing the behavior model with a different behavior model. This allows the behavior model to adapt to different circumstances, such as different usage patterns during weekdays, weekends, and vacations.
