The new infrared absorbing material was fabricated based on the formation (by cosputtering) of a vanadium-tungsten alloy film and its oxidation. The new bolometric material has TCR values in the range of -1.5 to -4.0 %/K, depending on the variation of tungsten concentration and oxidation time. The novel infrared absorbing material coupled microbolometer was fabricated by surface micromachining and its bolometric properties were characterized. Finally, the responsivity and noise voltage were measured as a function of chopper frequency, and detectivities of 0.9-6.0/spl times/10/sup 8/ cmHz/sup 1/2//W were obtained at chopper frequencies of 10-100 Hz and bias current of 33 /spl mu/A.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78451372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The substitutive central group of POTP influenced the characteristic rows of the potentiometric selectivity coefficient.

The selectivity of the central-amine tripodandes strongly depended on the substituting of the N-adjusted methylene group for the ethyleneglycol group.

Multi-dimensional combining (MDC) is proposed to combine the classification outputs of individual classifiers into a more robust and accurate one. Two implementations are proposed to find the individual classifiers, one is based on various feature extraction methods and the other is based on various dimension reduction methods, with three means of combining. Six household fragrances were sampled using the Cyranose 320 e-nose device. The acquired data (600 measurements) was split into two sets, training and testing. Experiments were conducted at various concentrations of the sample smell, various sample numbers and various training numbers. Results show the advantage of MDC over the individual classifiers, and over the other traditional PARC methods under all conditions.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72747121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A horizontal attenuated total reflection (ATR) unit connected to a portable IR-cube was used here to measure the IR absorption spectra of supernatant and microorganisms separately. The common problem of bio-film formation on the ATR was addressed before, e.g. by chemical means. We present a novel method employing the principles of ultrasonic particle manipulation to avoid and potentially remove this coating brought about by the use of fermentation broth. A novel flow cell for a horizontal ATR was developed that decreases measurement time and the undesired formation of bio-films on the ATR surface. An ultrasonic standing wave (/spl sim/2 MHz) is built up between a horizontal transducer and the ATR crystal. Yeast cells in suspension were agglomerated within certain regions by the ultrasound field and therefore settled about 3-4 times faster on the ATR when the field was switched off compared to the slow sedimentation of freely dispersed cells. After the IR spectrum had been measured, the same sound field was used to actively lift the settled material from the optical sensitive surface which therefore could be rinsed away more effectively.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73686727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For such applications to enter the consumer mainstream, it is necessary for them to operate far more power efficiently than they do currently. Using a simple illustrative example, this paper explores some general design rules for techniques which can reduce power consumption by one to two orders of magnitude through a combination of real-time sensor selection based on system state and in-situ feature extraction before storage and/or transmission (if necessary). In the presented example, it is demonstrated that the use of both low and high accuracy sensors for a single parameter (acceleration) can allow system state identification to be far more power-efficient (in this case, by 94%) than with a single sensor alone. Use of sensors with short wakeup times will further improve this result.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84253161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
