Abstract: The technology enables locating asset tracking tags based on a ramped sequence of signals from one or more beacon tracking tags. The sequence includes at least one minimum power signal and at least one maximum power signal. Each signal in the sequence has a tag identifier and an initial signal strength value. Each beacon signal in the ramped sequence is associated with the time at which that beacon signal was received by a reader. Each beacon signal is also associated with a received signal strength at reception. A location of the beacon tracking tag is estimated according to the signals in the sequence based on the difference between the initial and received signal strengths. A position of the reader device is identified based on the beacon tag's location. An asset tracking tag location is identified based on the reader's location and packets received by the reader from the asset tag.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for receiving, from one of two or more sensors of a device that independently determine whether an aircraft takeoff has likely occurred, an indication that the aircraft takeoff has likely occurred; activating, based on receiving the indication that the aircraft takeoff has likely occurred, an airplane mode of the device; receiving, while the device is in the airplane mode and from one of two or more other sensors of the device that independently determine that an aircraft flight is likely not occurring, an indication that the aircraft flight is likely not occurring; and deactivating, based on receiving the indication that the aircraft flight is likely not occurring, the airplane mode of the device. The indication that the aircraft takeoff has likely occurred may include acceleration data indicating an acceleration of the device in three dimensions.

Abstract: The technology enables locating asset tracking tags based on one or more beacon signals from at least one anchor beacon. Each of the beacon signals including anchor beacon identification information and being associated with a received signal strength upon receipt at a reader device. The anchor beacon identification information being associated with a physical location of the anchor beacon. A position of the reader device is estimated according to the received signal strength of the one or more beacon signals and the physical location of the at least one anchor beacon from the anchor beacon identification information. One or more signals from an asset tracking tag are detected by the reader device. A location of the asset tracking tag is identified based on the estimated position of the reader device and signal strength information for each of the one or more detected signals from the asset tracking tag.
