Abstract: A system and method is for determining a concentration of at least one gas in a container having at least one side with a flexible area. The system includes a measuring area arranged for receiving the container; a suction device arranged for pulling at least one portion of the flexible area a distance to arranging at least the portion of the flexible area in a position to provide a space underneath at least the portion of the flexible area; an optical sensor, configured to be sensitive to the at least one gas, is arranged in relation to the measuring area for transmitting a light signal through the space and detecting a transmitted light signal; and a controller configured for determining, based on the transmitted light signal, the concentration of the at least one gas in the container.

Abstract: 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.

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.

Abstract: A device, system and method for monitoring a pulmonary system of a subject. An optical member for emitting a light signal through a cavity of the pulmonary system of the subject. The optical member and a detector unit are configured to be positioned so that the light signal detected that has ebb transmitted from the optical member through the cavity. A control unit is configured for evaluating the detected light signal for determining a physiological status of said pulmonary system of the subject.

Abstract: 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.
