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.

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 can securely communicate with a secondary device by generating a hash value based on the identity of the tracking device. If the secondary device cannot resolve the hash value, the hash value can be provided to a tracking server, such as a cloud server, for resolving the hash value. Upon resolving the hash value, the tracking server can store a location of the tracking device in association with the identity of the tracking device. To preserve power, the secondary device can activate location-detection functionality (such as a GPS receive) only in response to the detection of movement of the tracking device, can obtain location information, and can de-activate the location-detection functionality upon providing the location information to the tracking server. The tracking server can associate one or both of a previous location and the current location information based on movement of the tracking device.

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: 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 first network device including first and second transceiver modules. The first transceiver module: during a first downlink period, transmits an uplink indication (UI) signal; and during an uplink period and subsequent to transmitting the UI signal, transmits a first data signal. The UI signal indicates when the first data signal is transmitted. The second transceiver module, prior to transmission of the UI signal, transmits a notice signal that indicates to a second network device not to transmit data to the second transceiver module during a second downlink period. The second downlink period is subsequent to an unused portion of the uplink period. The second transceiver module: transitions to a power save mode prior to transmission of the first data signal; and transmits a second data signal from the first network device based on the UI signal, subsequent to transmission of the first data signal, and during the unused portion.

Abstract: A first device having a first public key receives an identifier associated with a second device, and a second public key associated with the second device. The first device sends the identifier to the second device. The first device authenticates the second device using the first public key and the second public key. The first device receives a notification from the second device that the identifier sent to the second device corresponds to the second public key. The first device is used to enroll the second device in a first network including the first device based on receiving the notification. The first device is used to authorize a third device to enroll the second device in a second network including the first device and the third device after the second device is enrolled in the first network.

Abstract: A network device including first, second and third transceiver modules, which transmit or receive first, second and third data signals. A control module generates a mask signal based on a parameter of the first, second or third transceiver modules. The mask signal includes a direction bit and a first channel that identifies a first frequency. The direction bit indicates a range of frequencies. Transmission on the first frequency and some of the range of frequencies causes desensitization of the second data signal. A hopping module, based on a clock signal, selects a second channel for the third data signal. An output module, based on the mask signal and the second channel, generates an overlap signal indicating whether potential desensitization of the first or third data signal exists. An arbitration module, based on the overlap signal, provides the first or third transceiver module access to a first or second switch module.

Abstract: A tracking device can be reconfigured after an amount of operation to preserve the battery capacity of the tracking device and to ensure that the tracking device can be operated for a pre-determined threshold period of time. The tracking device can provide diagnostic information representative of a state of the tracking device, such as a current power capacity of the tracking device's battery, to a mobile device within a threshold proximity of the tracking device. The mobile device can then provide the diagnostic information to a tracking server, which in turn can provide reconfiguration instructions to the mobile device.
