US Patent 11922365 Smart-shipping container with security and communications capabilities

A portable device augments a shipping container with security and communications capabilities. The device includes multiple sensors, communications circuitry, and other electronic circuitry and/or mechanical components. The device can determine, based on output of the multiple sensors, an anomalous event experienced by the shipping container relative to an expected activity and communicate an indication of the anomalous event over a wireless network to a remote computer. The device also performs an action in response to the anomalous event or based on a command received from the remote computer.
