摘要： 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.

摘要： A method and system is disclosed for determining the integrity of a closed container. The method and system includes the steps of positioning the container in a surrounding, changing a gas pressure, a gas composition, a gas concentration, or any combination of gas pressure, gas concentration and gas composition, in the surrounding. Thereafter subjecting the container to an optical sensor, non-intrusively, the sensor being sensitive to at least one gas, and the sensor is configured for detecting the at least one gas inside the container. Reading a signal from the optical sensor related to a gas pressure, a gas concentration, a gas composition, or any combination of gas pressure, gas concentration, and gas composition, inside the container. The behavior of the signal being indicative of breach in integrity of the container.

摘要： A method and system for determining an integrity of a container, including obtaining a pressure inside a container by producing, filling and/or sealing a container using heat or at cold conditions. Transmitting a light signal through a headspace of the container and determining, based on the transmitted light signal being detected, the integrity of the container.

摘要： An system and method is disclosed for determining a concentration of at least one gas in a container. The system and method includes detecting light reflected by a surface inside or behind the container, or light refracted or scattered by the container, with a detector, wherein the detector provides a first signal related to an intensity of the reflected light, and a second signal related to a position of reflected light being detected. The first and second signals are used for estimating a concentration of the at least one gas inside the container.

摘要： The disclosure relates to system and method for determining the integrity of a container containing at least one gas. The disclosure relates to an environment with a lower absolute gas pressure than the pressure inside the container, a light source and a detector arranged to transmit a light signal to the detector through the environment, or a volume connected to the environment, but outside the container, and wherein a control unit for determining, based on said transmitted light signal being detected, if a level of the at least one gas inside the container is altered in the environment or the connected volume.
