摘要： Ultrasound is used to detect either or both the opening of a door of a shipping container or a change in the contents of a shipping container. Ultrasound signals transmitted from one or more ultrasonic transducers configured to be mounted within an interior of a shipping container travel through the interior and are reflected by a reflector, e.g., a corner reflector. The reflected ultrasound is received by an ultrasonic receiver, which produces an output signal corresponding to the received ultrasound signal. If the ultrasonic transducer or the reflector is mounted on the door, the time of flight of the ultrasound signal can be used to determine the distance that the ultrasound signal travels. Opening the door changes this distance, which can be detected. Similarly, changes in ultrasound reflected from contents in the shipping container can be detected and used to detect changes in the contents, which may be caused by terrorist activity.

摘要： Objects in a cargo shipping container are detected by measuring vibration resonant frequency peaks of the container. The mass of an object on the floor of the container effects the vibration resonance of the container, enabling the object to be detected. A vibration source and a plurality of accelerometers are either attached to the steel structure of the container, or are disposed on a supporting structure, such as a cargo crane or lift, so that they contact the container. The vibration source causes the container to vibrate, and the accelerometers detect the vibration resonance of the container. A mismatch between a cargo manifest and an observed cargo, or detection of an object having relatively high mass, e.g., due to lead shielding, can justify a manual inspection. The process uses synchronous processing to achieve the sensitivity needed, is unobtrusive, and does not slow the flow of cargo through a facility.
摘要翻译：通过测量容器的振动共振频率峰值来检测货物运输容器中的物体。容器地板上的物体的质量会影响容器的振动共振，从而能够检测物体。振动源和多个加速度计附接到容器的钢结构，或者设置在诸如货物起重机或电梯的支撑结构上，使得它们接触容器。振动源使容器振动，加速度计检测容器的振动共振。货物舱单和观察到的货物之间的不匹配，或者检测到具有较高质量的物体，例如由于铅屏蔽，可以证明是手动检查。该过程使用同步处理来实现所需的灵敏度，不引人注意，并且不会减慢通过设施的货物流动。
