A single ring-shaped electrostatic sensor is used to obtain a signal from which the two crucial parameters, velocity and mass flow rate of particles, may be derived for the purpose of monitoring and control. It is found that the quantified characteristics of the signal are related to the velocity and mass flow rate of particles. The relationships between the signal characteristics and the two measurands are established through the use of a back-propagation (BP) neural network. Results obtained on a laboratory test rig suggest that an electrostatic sensor in conjunction with a trained neural network may provide a simple, practical solution to the long standing industrial measurement problem","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124666630","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}

This paper presents an automatic approach to detect such erroneous sensors. It is based on the assumption that valid measurements are related by a reconstruction model, while measurements from erroneous sensors are unrelated. The method estimates the data at each sensor based on the measurements from all other sensors, and compares it to the measurements. The sensor-data match is tested using ANOVA to detect the presence of an erroneous sensor.

An experimental procedure for evaluating output SNR is presented: the desired signal is captured from a set location in the recording environment.

Such characteristics justify the interest of the scientific community on the development of accurate measurement techniques to monitor the dynamic behavior of capacitive MEMS switches during continuous actuations. In this paper, a novel measurement system devoted to the time-domain characterization of capacitive MEMS switches is proposed. Moreover, an electrical model for such devices is introduced and its lumped elements are characterized by means of measurement results. The proposed test-bench allows to measure the modulus and the phase of both the incident and the reflected signals of a one-port transmission line based, where the port is represented by the capacitive MEMS device. The paper introduces a software tool based on LabVIEWtrade to compute the capacitance and the resistance values of the model as functions of time. In particular the tool transforms the measured signals in the frequency domain to compute the reflection coefficient by means of components depending on the fundamental frequency of the RF signal, thus neglecting spurious frequency components, out-band noise and harmonics due to interferences","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121328019","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}
