  • Patent number: 7324921
    Abstract: The container inspection system operates globally at container handling facilities around the world and includes at least one transport apparatus located at a container handling facility having a spreader or other framework for connecting and handling cargo containers of all shapes and sizes. The transport apparatus is in communication with a computer network including several computing devices that provide to the transport apparatus comparison data including load models, load signatures, weight profile, and sensory limits related to a particular container. Sensors can be located on the spreader, inside the container, and invasively through the container and provide scanned characteristic data that is compared to the comparison data to determine a pass status or a fail status for the container. Ancillary data and authority input may be provided to the system by outside sources, such as other inspection systems and governmental entities.

  • Patent number: 7135976
    Abstract: The system of the invention includes a method for monitoring changes in the status or condition of a Container using one or more monitoring units mounted to the Container. The monitoring units preferably include a power supply, sensors using reflective energy with programmable parameters, globally-unique sensor identification, recording capability on a timeline, long term memory and the ability to rebroadcast information on RFID radio technology. Programmable monitoring hardware in the monitoring unit detects significant changes in the sensor outputs as a triggering event. The programmable monitoring hardware includes memory for storing identification information for the Container. The sensors which can include conventional devices that detect various forms of energy including visible light, infrared light, magnetic fields, radio frequency energy and sound. In one embodiment, a monitoring unit is mounted inside a shipping Container suitable for long distance transport.
