The coordinated physiological processes maintain most of the steady states in an organism, not at a fixed value, but within a narrow, relatively constant range, known as homeostasis. Recently, a non-invasive measurement of human biopotentials has been proposed in order to provide information about the condition of the human system as a whole. In the present work, a signal conditioning circuit has been developed to enhance the signal level of the measured biopotentials so as to achieve better resolution. This is expected to enable a more reliable and detailed analysis of the acquired signals.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"473 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131990059","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 gas sensing performances of thick films were tested for various gases. It showed maximum sensitivity to H2S at 300°C for 100 ppm. To improve the sensitivity and selectivity of the film towards a particular gas, TiO2 thick films were surface modified by dipping them in an aqueous solution of 0.01 M nickel acetate tetra hydrate for different intervals of time. These surface modified TiO2 film showed larger sensitivity to H2S gas (100 ppm) than pure TiO2 thick film at 300°C. Nickel oxide on the surface of the films acts as a catalyst and it increases reactivity of the films to H2S gas. A systematic study of sensing performance of the sensor indicates the key role-played by nickel oxide on the surface. The sensitivity, selectivity, response and recovery time of the sensor were measured and presented.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130188563","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 phenomenon of polarization by reflection of light from a transparent object differs from an opaque object. The specular reflection from the transparent object is highly polarized compared to the diffuse reflection from the opaque object. The differences in the polarization pattern can be recorded and can be used in machine vision applications like object classification and autonomous agent navigation. In this paper we present different methodologies like degree of polarization, polarization Fresnel ratio, Stokes degree of polarization to classify among transparent and opaque objects. Based on the polarization profile, the shapes of the transparent objects are also estimated.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130753203","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 proposed EM wave NDT system will be integrated into a wide variety of structural elements (e.g. automotive and construction) and will provide continuous real-time structural health monitoring of the materials. The system will be able to provide information related to the presence, type and location of damage or defects. Two sensors are studied for defect detection and monitoring, a rectangular patch structure and an interdigitated electrode structure. Initial experimental results demonstrate that the presence of defects such as cracks near the surface of the sensor elicit a change in sensor response. Detailed experimental set-up and preliminary measurement results are presented.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"148 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132949729","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}

Therefore we studied positioning and swing suppression of a boom crane using visual feedback control. The boom crane has broad working space, so we use a stereo vision installed on the boom's rotary axis that has gazing motion to track the suspended load. The three dimensional position and the swing angle of the load are measured using this tracking stereo vision. The experimental control results are presented concerning with the tracking of the stereo vision, the positioning of the boom and the swing suppression of the suspended load.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131316925","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}

Many of these applications require operation of the Bolometer arrays (thermal radiation detector), within a narrow temperature range, using power hungry temperature controllers. However, controller based systems always suffer from the finite time lag between “Power On” to “Ready for operation”. Sensor operation immediately at Power On, is a demand for time critical field applications such as fire fighting, night time rescue operations, etc. This paper describes an approach for temperature compensation and calibration of shutter-less Bolometer based thermal imaging camera, suitable for these time critical applications.

The solar corona can be observed either during occurrences of total solar eclipses when the bright photospheric light is blocked by moon or by using an instrument called the `coronagraph'. The existence of waves in the solar corona creates high frequency intensity, velocity and/ or line-width oscillations. These are interesting objectives for scientific community involved in research on solar physics. Amplitudes of these oscillations are feeble and need to be detected under high background photon flux. Photon noise generated by the background flux is significantly higher compared to peak signals generated by intensity oscillations. Identification of appropriate imaging detector and detection methodology to detect low amplitude oscillations overriding on high background flux is important for the design of coronagraph instrument. This paper discusses developed test setup to simulate intensity oscillations, with proposed detection methodology and also describes results of study carried out on two candidate imaging detector arrays.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117180238","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}
