摘要： A capture device for capturing a target gas from a gas flow is disclosed that can be continuously used without requiring consumption of target gas binding salts. To this end, the device is arranged to generate separate acidic and alkaline streams of fluid by electrolyzing water, binding the target gas to the hydroxide ions in the alkaline fluid stream or the hydronium ions in the acidic stream, and recombining the generated streams to release the bound target gas and regenerating part of the electrolyzed water for further electrolysis. Such a capture device may for instance be used in a gas purification system, e.g. an air purification system for controlling target gas levels in a confined space such as a vehicle cabin, domestic dwelling or office space, a target gas generation system or a target gas enrichment system, e.g. for creating target gas-rich air for horticultural purposes. A method for capturing target gas from a gas flow and optionally utilizing the captured target gas is also disclosed.

摘要： A particle sensor uses an electrostatic particle charging section in the form of an ionization chamber. A flow sensor arrangement is used to produce a signal which is representative of the amount of gas flow between the outside of the ionization chamber and the inside of the ionization chamber. This information is indicative of the flow conditions, and can be used to determine when adverse flow conditions are present which may adversely affect the performance or lifetime of the particle sensor.

摘要： A system for tissue inspection is provided, comprising a console (50) with a light source (64), a spectrometer (66), an optical switch (65) and a processing unit. The system further comprises an elongated shaft (10), wherein an illumination fiber (40), a plug (50) in front of the illumination fiber (40), and a detection fiber (41) is provided in the elongated shaft (10). The illumination fiber (40) is capable of transmitting light from the light source (64) to its front surface and is capable of transmitting light being back-reflected from the plug (50) to the optical switch (65). The detection fiber (41) is capable of transmitting light reflected from tissue in front of the distal end surface of the elongated shaft (10) to the optical switch (65). The optical switch (65) is configured to provide the back-reflected light to the spectrometer (66) for generating a reference spectrum and to provide the light reflected from the tissue to the spectrometer (66) for generating a diffuse reflectance spectrum. The processing unit is configured to generate a tissue spectrum by normalizing the diffuse reflectance spectrum with the reference spectrum.

摘要： A gamma photon detector for detecting 511 keV PET radiation includes a scintillator host material doped with cerium. The cerium is present in a concentration of 0.1 to 1.0 mol %. Lower concentrations increase light output but also decay times which can lead to pile up issues. The higher light output enables the read out area to be decreased which reduces the pile up issues. Embodiments with a cerium concentration as low as 0.15 to 0.2 mol % and a read out area as low as 0.1 cm2 are contemplated.
