Patent number: 11674898Abstract: 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.Type: GrantFiled: October 1, 2019Date of Patent: June 13, 2023Assignee: GasPorOx ABInventors: Märta Lewander Xu, Patrik Lundin

Patent number: 11378483Abstract: 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.Type: GrantFiled: October 16, 2018Date of Patent: July 5, 2022Inventors: Märta Lewander Xu, Patrik Lundin, Mikael Sebesta, Axel Fredrik Bohman, Lee Michael Vine
