Interested parties would like to know the identity o the semi-truck to which a semi-trailer is coupled. They would like to know when and where the semi-truck was coupled to and uncoupled from the semi-trailer. The embodiments all detect the semi-truck's identity. Some embodiments compute the identity of the semi-truck in environments where multiple semi-trucks are nearby. Some embodiments report the semi-truck's identity by wireless modem to said interested parties. Some embodiments detect and report the geolocation of the semi-trailer.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.

A long-distance radio frequency electronic identification tire structure is provided. When the production of the tire is completed and an electronic tag reading device is used for identification, an RFID chip of an ultra high frequency electronic tag of a main tire body receives and sends an electromagnetic wave signal generated by a far-field copper film antenna and the electronic tag reading device. The frequency band and the bandwidth of the electromagnetic wave signal are adjusted by a frequency band/bandwidth adjustment portion, and first and second field effect adjustment grooves of first and second field effect adjustment portions are configured to adjust the field effect when a tire bead bundle and a steel belt layer reflect the electromagnetic wave signal, so that the electronic tag reading device can read the identification code of the ultra high frequency electronic tag at a wide angle and a long distance.
