Abstract: The present invention relates to a sensor (1) for sensing organic carbon in a liquid (L), comprising: a container (2) having an interior space (20) for receiving the liquid (L), a photodetector (3), and a light source (4) configured to emit ultraviolet light (5) so that the ultraviolet light (5) travels along an optical path (P) through liquid (L) residing in the interior space (20) and is absorbable by carbon bonds of organic molecules in the liquid (L). According to the present invention, the photodetector (3) is configured to detect light in the visible or infrared spectrum, and the sensor (1) comprises a down conversion material portion (22; 22a) arranged in the optical path, wherein the down conversion material portion (22; 22a) is configured to receive incoming ultraviolet light (5) emitted by the light source (4) and to down convert received ultraviolet light (5) and to emit said down converted light (50) in the visible or infrared spectrum so that emitted down converted light (50) impinges on the photodetector (3).

Abstract: A gas generator comprises a compartment confined by a casing configured to hold an active material generating a target gas in response to thermal activation, and a heater structure configured and arranged to heat the active material for generating the target gas. The heater structure is arranged outside the compartment and heats the active material from at least two sides.

Abstract: A device for holding a target gas comprises a compartment configured to hold the target gas. The device further comprises a gas generator configured and arranged to release the target gas in the compartment in response to a control signal. The device further comprises a reference sensor sensitive to the target gas and arranged to supply a sensor signal representing a concentration of the target gas in the compartment. A control unit is provided and configured to control the release of the target gas from the gas generator by way of the control signal, dependent on the sensor signal. The gas generator and the reference sensor are arranged in the compartment.

Abstract: An infrared device comprises a substrate (1), and arranged on or in the substrate (1) a configuration (3) for one of selectively emitting and selectively absorbing infrared radiation of a band, the configuration (3) comprising a pattern made from an electrically conducting material on a first level (L1), an electrically conducting film (33) on a second level (L2), and a dielectric layer (24) between the pattern and the film (33). One or more of a heater (4) for heating the configuration (3), and a thermal sensor (5) arranged for sensing the selective infrared radiation of the band absorbed by the configuration (3) on or in the substrate.
