The principle of operation of the module consists of the NDIR method. The basic assumption for construction of this model was using of directly modulated thermal IR source in it. A few models of IR sources were worked out. Their heaters were made from thick platinum layers and foil. Limits of modulation frequency for IR sources were greater than 30 Hz. The detection module consists of an optical part, analogue electronics and microprocessor system with a suitable program. The time dependent concentration of CO2, end tidal concentration of CO2, mean concentration of N2O and breath frequency are output values of the detection module. Measurements are executed 30 times per second. The accuracy of CO2 concentration measurement equals to 5%.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131039254","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}

Radio links dominate in remote transmission. By means of open optical fiber links, it is possible to transmit data over short distances between objects. Depending on the technology used, it is possible to connect transmitting-receiving systems distant from one another by approximately twenty cm to twenty meters. Basic problems accompanying transmission to open optical links include the need for direct or indirect sensing of optical radiation from the emitter by the detector and the inherent propensity for interference. Among its advantages are: the possibility of obtaining greater data transmission speeds and an ease in changing direction, the difficulty posed to unwanted remote “viewing”, and the miniaturization of links. This paper presents basic open configurations of optical links used in data transmission with selected time-varying signals. Using remote transmission of data between a computer and mobile minirobot is shown.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125476318","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}

One of the solutions is the system of two hot-wire anemometers which enable to measure velocity and temperature in non-isothermal gas flows. The output signals come from two hot-wire anemometers operating at different overheat ratio. As the two sensors operate in a CTA mode, we get a wide range of frequency bandwidth for velocity and temperature measurements.

Application of various methods of investigations is necessary in the course of getting increased knowledge of the phenomenon. Flow visualization being the leading method of aero- and hydrodynamic phenomena investigations enables qualitative evaluation in micro-scale. Due to the image processing application in analysis of flow visualization pictures, calculation of geometrical parameters of the Karman vortex street is feasible. So, the quantitative information is obtained. The worked out methodology of investigations as well as designed software for analysis of vortex street pictures are described in the paper. The results of the carried out laboratory tests are reported. Flow visualization has been carried out on the especially designed laboratory tests are reported. Flow visualization has been carried out on the especially designed laboratory stand. The visualized flow has been recorded on the magnetic tape and then processed into set of consecutive frames. Four groups of frames of similar vortex development phases have been put on the image processing procedure. Distances between adjoining vortices have been calculated. On the basis of obtained results it can be stated, that in spite of probabilistic nature of the investigated phenomenon strengthened by the applied research method (flow visualization), the proposed method enables quantitative determination of Karman vortex street parameters.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"85 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116202289","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}

It has been stated that the additives modify the anisotropy of the etching process, which results in reduction of etch rates of some crystal planes with specific configuration of surfacial bonds. After considering the bonds configuration on these planes and alcohol molecules dimensions it has been stated that the effective blocking of these planes is directly related to their spatial structure and the structure of alcohol molecule. Obtained results should enable deliberate selection of the additives to etching solutions and the choice of solutions compositions, assuring possible small undercut of convex corners.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125334113","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}
