Abstract This paper deals with the discrimination of gases using the responses of an integrated gas sensor. The multiple regression method is used to find the sensor parameters for different gases in training mode. In sniffing mode, these parameters are used to discriminate the gases present in the ambient using the iteration technique. These methods, , the multiple regression method and ...

A hybrid intelligent gas array sensor (or electronic nose) has been constructed, which comprises 10 CHEMFET devices, four Taguchi gas sensors (TGS), one infrared CO 2 sensor and a microcomputer in order to examine the odours from five cardboard papers from commercial manufacturers. Four of the papers came from two different production lines of the same Swedish manufacturer; the duplicate …

The main motivation for tin oxide gas sensor array based devices is the development of a qualitative, lowcost, realtime, and portable method to perform reliable, objective, and reproducible measures of volatile compounds and odors. In the past these devices (electronic noses) have been developed for the classification and recognition of a large variety of foods, such as juices[2], coffee[9 ...

manufacturers and industry to redesign airfuel mixture systems to control toxic gas emissions and smog levels [1]. Automobile manufacturers and other industries use sensors interfaced with computer controlled fuel systems to increase fuel economy and to control toxic emissions to meet regulations set by federal agencies [2]. A wide variety of metal oxide materials have been investigated for ...

A feature extraction method is proposed for discriminating three kinds of Chinese vinegars based on a gas sensor array composed of 13 Taguchi gas sensors (TGS). It employs threescale wavelet packet analysis to decompose each signal of the sensor array into eight difference frequency bands, and the feature values can be obtained by computing the maximum of relative energy corresponding to each ...

The detection of gases found in atmosphere such as: Carbon dioxide, Hydrogen and Methane depend on Taguchi gas sensors by varying the load resistance of each sensor, which can increase sensibility and selectivity of gas detection. This paper provides the measurement setup for gas detection by using variation in load resistance and calibration curves of each gas with different concentrations ...

manufacturers consider whether or not a product is good. The traditional approach employed by manufacturers (as evidenced by SonyUSA) has been to use a “step function” that ensures that performance fell within the upper and lower specification limits as shown in Figure 2a. Figure 2 Quality Loss Function (Phadke, 1989) Taguchi’s loss function can be expressed in terms of the ...

The gas sensor array has been tested to observe the specific response with various volatile organic compounds (VOCs) in a static system. These sensors are appropriate for detecting the microbial ...

Taguchi Methods Also known as Robust Design, Taguchi Methods include both design of experiments concepts, and a particular philosophy for design in a more general sense ( manufacturing design). Taguchi sought to improve the quality of manufactured goods, and advocated the notion that ‘quality’ should correspond to low variance. These ideas are wellillustrated by an …

Pandemicrelated shutdowns have affected manufacturers across Asia. In Japan, factory production in August fell by percent from the month before. Automakers and producers of information technology products and other electronic equipment were the hardest hit, the Japanese government reported. Other automakers also have slowed operations. They say shortages of computer chips and other parts ...
