Container security system with oscillation device and method for performing container handling using container security system with oscillation device
First Claim
1. A container security system comprising:
- force sensors and acceleration sensors attached to a lifting beam of a container handling device or to a frame of the container handling device;
an oscillation device attached to the lifting beam of the container handling device or to the frame of the container handling device and arranged to create oscillation of a container during a container handling stage in which the container is empty; and
an electronics unit arranged, during the container handling stage,(i) to generate a second code for the empty container based on elasticity of the empty container during the container handling stage, the elasticity being determined by measurement of the created oscillation by the force sensors and acceleration sensors and analysis of results of the measurement, and(ii) to recognize a change in a condition of the container by comparison of the second code to a first code, which is based on elasticity of the container when empty during a prior container handling stage, whereinthe comparison of the first code and the second code does not require change of mass of the container.

Abstract
A container security system is disclosed that includes force sensors and acceleration sensors attached to a lifting beam of a container handling device or to another part of a frame of the container handling device. The container security system also includes an electronics unit and an oscillation device attached to the lifting beam of the container handling device or to another part of the frame of the container handling device. The oscillation device creates oscillation of a container and contents of the container, and the container security system recognizes (i) a change in a condition of the container or the container contents as well as (ii) a change in an amount of the container contents between different container handling stages.

11. A method for performing container handling with a container security system, the method comprising:
-
in a container handling stage of the container security system in which a container is empty, producing by way of an oscillation device a mechanical oscillation directed onto the empty container; during the oscillation produced in the container handling stage, creating for the container, based on signals received from force sensors and acceleration sensors, a container-specific code based on elasticity of the container; and during the container handling stage, comparing the container-specific code to another code that is based on elasticity of the container obtained from a prior container handling stage during which the container is also empty and that is retrieved from a database of the container security system, wherein the comparison of the container-specific code and the other code does not require change of mass of the container. - View Dependent Claims (12, 13, 14, 15, 16)
