Patent attributes
Method for monitoring a cargo container in which a transmitter is arranged on the container and periodically transmits messages to a remote site or location according to a schedule of messages. When a message is not received according to the schedule, which may be the result of tampering with the transmitter or another nefarious action involving the container, it may be considered that the container has been stolen. A rate of transmission of the messages may be modified based on a condition of the vehicle, such as the presence of a driver inside the vehicle, a distance between a driver inside the vehicle and the vehicle, the vehicle being at rest after motion of the vehicle stops, a location of the vehicle, biometric identification of a driver of the vehicle and deviation of the vehicle from an expected route, and/or based on current time and weather around the vehicle.
