System for monitoring containers to maintain the security thereof
First Claim
1. A device for determining whether a security breach of a container has occurred, the container including a door and a frame, the device comprising:
- a door sensor;
an interface for attachment of an additional sensor to monitor an internal condition of the container;
a microprocessor coupled with the interface and configured to discern a door event from the door sensor, wherein the door event includes at least opening the door after the container has been secured,wherein the sensor is configured to sense at least one of a distance value and an angle value that separates the door from the frame.

Abstract
A container and contents monitoring system includes a device, a reader, a server, and a software backbone. The device communicates with the reader in order to determine the security of the container to which the device is attached. The reader transmits the information from the device to the server. The sensor senses a distance or an angle value between a door of the container and a frame of the container and the sensed value is then transmitted to the device. The device obtains a baseline value that is related to a calculated mean value. The device also obtains a detection threshold. The device determines if a security condition has occurred based on the sensed value and the detection threshold.
