Patent number: 11815452Abstract: A gas sensor device (100) is configured to measure a predetermined gas of interest and comprises an enclosure (101) comprising a semiconductor substrate (102) and defining a first cavity (124), an optically transmissive second closed cavity (126) and a third cavity (128). The second cavity (126) is interposed between the first and third cavities (124, 128). The first cavity (124) comprises an inlet port (130) for receiving a gas under test, an outlet port (132) for venting the gas under test. The first cavity (124) also comprises an optical source (112) and a measurement sensor (114). The second cavity (126) is configured as a gaseous filter comprising a volume of the gas of interest sealingly disposed in the second cavity (126), and the third cavity (128) comprises a reference measurement sensor (116) disposed therein.Type: GrantFiled: October 7, 2020Date of Patent: November 14, 2023Assignee: MELEXIS TECHNOLOGIES NVInventors: Wouter Leten, Joris Roels, Xiaoning Jia, Roeland Baets, Gunther Roelkens

Patent number: 11287514Abstract: A sensor device (100) comprises an emitter device (106) arranged to emit electromagnetic radiation and having an emission region associated therewith. The sensor device (100) also comprises a detector device (108) arranged to receive electromagnetic radiation and having a detection region associated therewith, and an optical system (122). The emission region is spaced at a predetermined distance from the detection region. The optical system (122) defines a plurality of principal rays, a number of the plurality of principal rays intersecting the detection region. The number of the plurality of principal rays also intersect the emission region.Type: GrantFiled: October 2, 2018Date of Patent: March 29, 2022Assignee: MELEXIS TECHNOLOGIES NVInventors: Gaetan Koers, Wouter Leten, Sam Maddalena, Ross Kay
