Abstract
A method or system of determining integrity of a closed container comprising at least one gas. The determination is based on applying a mechanical force to at least one side of the container and transmitting a light signal across at least a portion of an outside surface of at least one side of the container using an optical sensor. The optical sensor is sensitive to the at least one gas inside the container. Detecting a transmitted light signal and determining, based on the detected light signal, if the at least one gas inside the container has been detected outside of the container.
Claims20
A method of determining integrity of a closed container comprising at least one gas, said method comprising:
- applying a mechanical force to at least one side of said container, forcing said at least one gas inside said container to leak out by at least partially deforming said container by said mechanical force;
- emitting a light signal using an optical sensor, and wherein said light signal is transmitted across at least a portion of an outside surface of at least one side of said container and through said at least one gas leaked out from said container;
- said optical sensor being sensitive to said at least one gas inside said container;
- detecting a transmitted light signal related to said emitted light signal;
- determining, based on said transmitted light signal being detected, when a level of said at least one gas inside said container has changed outside of said container.
A system for determining integrity of a sealed container comprising at least one gas, said system comprising:
- a deformation member for applying a mechanical force to at least one side of said container to force said at least one gas inside said container to leak out by at least partially deforming said container by said mechanical force;
- an optical sensor sensitive to said at least one gas, and said sensor is configured for emitting a light signal and wherein said optical sensor is configured for transmitting said light signal across at least a portion of an outside surface of at least one side of said container, and said sensor is further configured for detecting a transmitted light signal related to said light signal;
- a control unit for determining, based on a detected transmitted light signal, when a level of said at least one gas inside said container has changed outside of said container.
