New surface acoustic wave gas sensor of the mass-sensitive type sensitive to the thermal properties of gasesSENSORS, 2002 IEEE - Tập 1 - Trang 372-375 vol.1
The basic principles of a new surface acoustic wave (SAW) gas sensor are described. Being essentially a sensor of the mass-sensitive type, the proposed device possesses certain features of the thermometric SAW sensors and is not only sensitive to the vapors of volatile substances, but capable of detecting gases by their thermal properties as well. This principles consists of making a certain delay...... hiện toàn bộ

Temperature dependences of fibre-optical sensors of mechanical valuesProceedings. 3rd Annual Siberian Russian Workshop on Electron Devices and Materials - Tập 1 - Trang 3 pp. - 2002
In the work the temperature dependences of the fibre-optical sensor of mechanical values are explored. The examinations of influence of temperature changes on the transmitting characteristic of FOS were spend. As a sensing device the silicon membrane with width h1=40 micron with strong centre by width h3=200 micron was used. The measuring were spend at temperatures T1=20/spl deg/C, T2=60/spl deg/C...... hiện toàn bộ

Shoreline feature extraction from remotely-sensed imageryIEEE International Geoscience and Remote Sensing Symposium - Tập 6 - Trang 3417-3419 vol.6
Different methods of delineation were used to extract shoreline features from images with different spatial and spectral resolutions acquired by airborne and spaceborne sensors. The exact location of the shoreline is difficult to obtain from the images and therefore the definition of shoreline was based upon the geomorphological and oceanographic characteristics of the area of study. Extracted sho...... hiện toàn bộ

Current sensor in PCB technologySENSORS, 2002 IEEE - Tập 2 - Trang 779-784 vol.2
A novel DC/AC current sensor works on the fluxgate principle. The core in the form of a 7/10 mm ring made of electrodeposited Permalloy is sandwiched into the middle of the printed circuit board (PCB), while the sensor excitation winding is also integrated in the copper layers of the PCB. In order to lower the sensor power consumption, the excitation winding was tuned by a parallel capacitor. The ...... hiện toàn bộ

A novel processing for multiple gases detectionProceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 3 - Trang 2186-2189 vol.3
It is difficult to detect multiple gases by single chemical sensor because of nonlinear and complicated relations between multiple gas and surface of sensitive materials. In this paper, the technology of multisensor data fusion is applied to detect multiple gases. It is presented a novel detection method based on multiobjective genetic algorithm(MOGA) for analyzing and distinguishing each componen...... hiện toàn bộ

Comparison of surface H-field measurements using Hall sensors and a novel multiple sense coil approachSENSORS, 2002 IEEE - Tập 2 - Trang 795-799 vol.2
Resulting from the magnetoelastic phenomena, measurement of magnetic properties of ferromagnetic materials has found many applications in evaluation of stress and force. Therefore a reliable way of measuring magnetic field is imperative. Measurements of initial magnetization curve and hysteretic curve using three Hall sensors placed at different distances from the surface of the material are compa...... hiện toàn bộ

Situation assessment using graphical modelsProceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 886-893 vol.2
This paper presents a Bayesian network framework for situation assessment. The framework is generated from a set of technical requirements that would be a prerequisite for any situation assessment system. It is shown that Bayesian networks readily satisfy these requirements and produce a system that readily fits into the Endsley (1995) description of situation assessment. The framework can also be...... hiện toàn bộ

Implantable glucose sensor: progress and problemsSENSORS, 2002 IEEE - Tập 1 - Trang 270-273 vol.1
Although the first implantable glucose sensors were developed a few decades ago, there is still no glucose sensor that can work reliably and for a long period of time after implantation. This loss of function in vivo is caused by events that affect the sensor itself (e.g. degradation, fouling...), as well as by changes in the tissue surrounding the sensor, caused by the implantation. Therefore, in...... hiện toàn bộ
