  • Publication number: 20240289728
    Abstract: Methods and systems for controlling an asset tracking device and, in particular, determining when an asset tracking device is aboard a ship. The device may have a ship mode in which the device determines it has been loaded onto a ship and in which geolocation is not determined. The device may further have an ocean mode to which it transitions from the ship mode in which it ceases to look for a cellular connection in order to send location reports. The device may detect a beacon signal from a ship-mounted base-station to trigger the ship mode and may detect, or fail to detect, one or more wireless signals or identifiers as the trigger to transition to ocean mode.

  • Patent number: 11988771
    Abstract: Systems and methods for determining a presence of cargo within a container are described. The determination may comprise transmitting a first electromagnetic signal within the container and receiving a first reflected electromagnetic signal corresponding to the first electromagnetic signal. The first reflected electromagnetic signal may be converted into a set of first magnitude values corresponding to a set of bin values representing a respective distance from the radar device. The first magnitude values may be integrated, using a moving window, over successive subranges of bin values to produce a set of integrated magnitude values. A set of integrated base magnitude values may be subtracted from the set of integrated magnitude values to produce a set of normalized integrated magnitude values. A presence of cargo within the container may then be determined by comparing each of the normalized integrated magnitude values with corresponding threshold values.
