Method and 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 device comprising:
- a sensor for detecting a distance or an angle value between a door of the container and a frame of the container; and
a microprocessor for establishing a baseline value, the baseline value being related to a calculated mean value from at least two detections, the microprocessor also adapted to define a detection threshold and determine from the detection threshold and the distance or angle value whether a security breach has occurred.

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.

21. A method of detecting a security breach of a container, the method comprising:
-
placing a proximity sensor adjacent a structural member and a door of the container, the proximity sensor obtaining a sensed value;
converting the sensed value to a distance value via a data unit located within the container;
determining, by the data unit, whether a security breach of the door has occurred based on the distance value;
communicating, by the data unit, a result of the determining step to an antenna interoperably connected to the data unit and located adjacent to and outside of the container; and
transmitting, by the antenna, information relative to the communicating step. - View Dependent Claims (22, 23)

24. A device for determining a security condition of a container and its contents, the device comprising:
-
a sensor for detecting at least one of a distance condition and an angle condition of the container and its contents; and
a microprocessor for receiving the at least one distance condition and angle condition from the sensor and to establish a range of acceptable condition values, the range of acceptable condition values being related to normal fluctuations in the sensed conditions of the container and its contents experienced during transport, the microprocessor also for determining from a defined condition threshold and the sensed condition, the security condition of the container. - View Dependent Claims (25, 26, 27, 28)
