Systems and methods are described for transmitting broadcasts by Peripherals, receiving the broadcasts by Centrals, and communicating with a Backend by Centrals. Specifically, a Peripheral may generate and transmit an encrypted broadcast packet to a Central, the Central may transmit the encrypted observation information to the Backend, which may decrypt the broadcast packet. Additionally, a Central may transmit a request for authorization to connect to a Peripheral to the Backend. If authorized by the Backend, the Central may connect to the Peripheral. Further, a Central may receive a plurality of broadcasts over a period of time. The Central may store information about the broadcasts and, at the conclusion of the period of time, transmit the information about the broadcasts and the last-received broadcast to the Backend.

Anonymization in a low power physical asset tracking system

An object tracking device, such as may be attached to a trailer to track movements of the trailer, may have various communication capabilities, such as cellular/LTE, Wi-Fi and GPS, which each have varying power requirements. A power optimization routine determines which communications should be performed to conserve battery while also providing frequent location updates. The routine determines if another plugged in tracking device is within low power Bluetooth (BLE) range and, if so, communications location via that device. If not, a Wi-Fi scan is performed and a lookup table is consulted for the corresponding location of any identified Wi-Fi access points. If location data cannot be found for an identified Wi-Fi access point, GPS location of the device is determined and the lookup table is updated to include the GPS location of the Wi-Fi access point.

Power optimized geolocation

A method for estimating a remaining battery life of a non-rechargeable battery of an Internet of Things (IoT) device. The method includes determining an amount of battery capacity used by the IoT device while the IoT device was operating in an active mode, an amount of battery capacity used by the IoT device while the IoT device was operating in a sleep mode, and an amount of self-discharge of the non-rechargeable battery while the IoT was deployed based on temperatures of environments in which the IoT device was located. The method further includes determining an estimated remaining battery life of the non-rechargeable battery based on an initial capacity of the non-rechargeable battery, the amounts of battery capacity used by the IoT device while the IoT device was operating in the active mode and the sleep mode, and the amount of self-discharge of the non-rechargeable battery while the IT was deployed.

Battery life estimation

Systems and methods are described for determining a peripheral's location based on observations from a plurality of centrals. A central may periodically transmit its location and observations of peripherals to a backend. The backend may match the location of the central with one or more observations of a peripheral to estimate a location of the peripheral. The backend may receive observations of the same peripheral from a plurality of centrals. The backend may aggregate estimated locations to triangulate a more precise location of the peripheral.

Low power physical asset location determination

Rolling encryption and authentication in a low power physical asset tracking system

An air quality notification system to perform operations that include: causing a sensor device to sample an air quality associated with a location at a predefined sampling interval; determining, at the sensor device, that a value corresponding with the air quality sampled by the sensor device transgresses a threshold value; causing the sensor device to transmit an alert to a server system responsive to the determining that the value corresponding with the air quality transgresses a threshold value; and causing the server system to present a notification at a client device responsive to the sensor device transmitting the alert, the notification including at least a display of an identifier associated with the location.

Air quality notification system

Systems and methods are described for connection throttling between peripherals and centrals. Connections may enable bi-directional communication between a peripheral and a central to allow for updates to or configuration of the peripheral. The peripheral can send broadcasts to centrals. The broadcasts may contain metadata indicating a time period since the peripheral last connected to a central, a maximum connection distance, and a transmit power or signal strength indicator. The central may use the transmit power or signal strength indicator to determine a distance from the central to the peripheral and may determine whether the distance is within the maximum connection distance. The central may determine to connect to the peripheral based on time and distance thresholds being satisfied. Upon establishing of a successful connection, the central can update or configure the peripheral.
