Abstract: For efficiently generating training data, a main device includes a processor. The processor performs: a wear determination process of determining, in view of an output signal from a sub-sensor provided close to an odor sensor associated with a service user, whether the odor sensor is worn by the service user; a first acquisition process of acquiring an output signal from the odor sensor; a second acquisition process of acquiring type information indicative of a type of excretion of the service user, which has been determined by a service provider; and a training data generation process of generating h includes sensor information indicative of the output signal having been acquired in the first acquisition process from the odor sensor that has been, in the wear determination process, determined to be worn by the service user and which includes the type information having been acquired in the second acquisition process.

Abstract: An additive manufacturing system comprising at least one electronic nose (e-nose) is provided. The e-nose may comprise a housing and gas sensors. The housing may have an air channel. The active sensor portion of the sensors are positioned in the air channel. The housing may be mounted to an extruder head of an additive manufacturing device. The system may also comprise a processor. The processor may determine whether there is an abnormality in an additive manufacturing process based on one or more combinations of outputs from the gas sensors received during the additive manufacturing process input into a deployed machine learning model; and generate a report for the additive manufacturing process containing the determination.

Abstract: Provided is a gas sensor element or the like in which a diffusion mode of NOx reaching a measurement electrode is changed from molecular diffusion to a mode of diffusing while repeatedly colliding with a wall face of a sufficiently narrow flow path. In a gas sensor element according to one aspect of the present invention, a porous diffusion layer covering a measurement electrode has a porosity that is lower than the porosity of a leading end protection layer covering at least a face of an element substrate in which a gas inlet is open, and that is 5% or more and 25% or less.

Abstract: A concentration sensor assembly can include a vaporization chamber having a compound. The concentration sensor assembly may include a first flow path coupled to the vaporization chamber. The first flow path may direct a first gas to the vaporization chamber. A second flow path can direct a second gas out of the vaporization chamber. The second gas can include the compound and the first gas. A first sensor is disposed along the first flow path. The first sensor measures first data indicative of a first mass flow rate of the first gas. A second sensor is disposed along the second flow path. The second sensor measure second data indicative of a second mass flow rate of the second gas. A computing device may determine a concentration of the vaporizable substance within the second gas based on the first data and the second data.

Abstract: A gas analyzer includes: a column that separates a component in a sample gas; a valve that switches, between a test sample gas and a standard sample gas, the sample gas to be supplied to the column; a valve that adjusts an introduction amount of the sample gas to be supplied to the column; a detector that detects, by gas chromatography, the component in the sample gas separated by the column; and a control device. The control device controls the valve to allow the introduction amount to be a predetermined amount, calculates a peak area value of a chromatogram obtained by the detector when the introduction amount is the predetermined amount, and calculates a correspondence between the introduction amount and the peak area value.
