Our work aims at providing an architecture for fault-tolerant sensors and offering a uniform interface to the application. In the paper, we present our fault-tolerant virtual sensor concept that is based on combining model-based estimation and redundant sensor data. To illustrate and evaluate our concept we simulate a mobile robot in an instrumented environment which integrates several smart position sensors. By using a mathematical model to evaluate sensor data we achieve a more reliable position estimation.

Commercial NOx sensors provide a measure influenced both by the temperature and by the presence of other substances to which the device is sensitive.

Thanks to accurate sensors models, it is possible to develop an algorithm that provides a precise estimation of NOx concentration using the data collected from all sensors.

The system has been developed in the frame of an investigation on MEMS based sensors for the detection of very low g accelerations.

A Simulink-based approach is proposed for fast, accurate and reconfigurable modeling of the measuring system (sensor plus acquisition chain). The paper shows how such models are essentials to exactly predict the distortion and noise sources, to allow for fast set-up of the experiments, and to manage the signal conditioning process. The validity of the proposed technique is assessed by comparing the predicted results with tests on the real implemented system.","PeriodicalId":107220,"journal":{"name":"2009 IEEE International Workshop on Robotic and Sensors Environments","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129232492","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}

Additionally, the fiber optic sensors are practically able to operate the remote sensing due to stable transmission fiber line. Especially, hetero-core optical fiber sensors for environmental monitoring system have several advantages such as high accuracy, repeatability and temperature independency. This paper reports a novel approach to dynamic measurements for vibrations of the window using two types of the hetero-core optical fiber vibration sensors. A first vibration sensor can detect a vibration with high sensitivity due to effectively convert the vibration into change in the curvature of the fiber sensor. A second type of vibration sensor, which is lower sensitivity than the first type sensor, can detect vibrations with a few millimeters in thickness. It is shown that the vibration frequency depends on a fiber length of the two fixed points. A characteristic of spectrum peak shows the relatively wide frequency bands with ranging from 400 to 5000 Hz and from 1000 to 4500 Hz as the fixed points distances in the ranges of 15–45 mm and 10–25 mm for the first and second types of sensors, respectively.","PeriodicalId":107220,"journal":{"name":"2009 IEEE International Workshop on Robotic and Sensors Environments","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127420460","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}
