摘要： The invention relates to method and apparatus for the determination of alcohol concentration of expired air. By visualising current or accumulated measuring value and error in real time during ongoing measurement, interactive control of alcohol determination is enabled with respect to accuracy and time lapse. Preferably the measurement is performed without contact with compensation for the dilution of the breath sample, which is performed by simultaneous measurement of temperature, concentration of water vapour or carbon dioxide. The method is divided into a stepwise procedure based on the dependence of the measuring error on the dilution of the expired air, and accumulated time, both being possible to influence by the test person or operator. Special advantages are being obtained at measurements relative to a concentration limit. The alcohol determination is preferably performed by means of absorption spectroscopy within the infrared wavelength range. The apparatus according to the invention includes sensors for the abovementioned entities, an electronic unit for signal and data processing, a presentation unit, and is embedded in a compact housing for handheld use or integration. The response time of the sensors should not exceed 0.5 seconds in order to fulfil the requirement of real time operation. The housing is controllably openable at measurement, and includes a measuring cell illuminated with collimated infrared radiation and means for active air flow.

摘要： A sensor for monitoring gas content. The sensor comprises a housing defining at least two cavities and a resonating structure positioned in each of the cavities. Each of the resonating structures has a resonant frequency dependent upon a physical characteristic of a gas in its respective cavity. Means for exciting the resonating structures generates output signals therefrom, and means compares the output signals from each of the resonating structures and outputs a comparison signal indicative of a difference between the resonant frequencies of the two structures and the relative gas content of the at least two cavities.

摘要： A method and apparatus for breath analysis from a test person who may be incapable of delivering controlled forced expiration. Breath sampling may be essentially contactless and is provided by active air intake to measuring cell (4) via receptor (2) which exhibits concentration preserving effect based on partial reflow which prevents mixing with ambient air. The analysis is performed by IR spectroscopy, including the determination of concentration of a volatile organic substance, e g ethyl alcohol, and a physiological reference substance, e g carbon dioxide. The timing of sampling is controlled by starting command from operator, and the duration of air intake is controlled by sensor signal from the measuring cell. The apparatus includes one hand unit (1), an exchangeable receptor (2), and a docking station (3).

摘要： L'invention se rapporte à un détecteur de respiration acoustique, qui est composé d'au moins deux conduits de transmission d'air tubulaires (1, 2, 11, 12) dont chacune des extrémités est reliée à des éléments de microphone (22, 23). A proximité des autres extrémités des conduits se trouvent des ouvertures (6, 7), au niveau desquelles des turbulences et, partant des signaux acoustiques sont créés par l'incidence du flux d'air dû aux phénomènes respiratoires. Un élément de support (5) permet de fixer les ouvertures (6, 7) par rapport à la bouche ou au nez du sujet dont la fonction respiratoire doit être contrôlée, et un élément directeur de flux (8), formé par exemple par un masque facial (9), dirige le flux d'air vers les ouvertures (6, 7). Les éléments de microphone (22, 23) sont reliés dans un circuit en pont à deux conducteurs d'amenée de tension (17, 19) et à au moins un conducteur de signaux (18). Ainsi, la sensibilité de l'appareil aux perturbations mécaniques et acoustiques est supprimée.

摘要： A sensor for the measurement of carbon dioxide concentration within an air flow being input to a measuring cell (1) connected to at least one electroacoustic element (2, 3) for transmitting and receiving airborne acoustic waves within the measuring cell (1). The output signal of the sensor corresponds to the propagation velocity of these waves and an indirect measure of carbon dioxide concentration, with an automatic offset correction functionality for compensation of undesired offset variations of the signal, caused by temperature or humidity variations. Preferably, an accumulating function for minimizing the influence of the offset variations is included, which for humidity variations may consist of a material with high porosity and surface density of polar molecular groups. Temperature control of the inner sheath (4) is effected by a temperature sensor (11), a resistive heating element (12) in good thermal contact with the inner sheath (4), and a control circuit (13).
