The measurement principle is based on the determination of the phase shift between a received optical signal and an electrical modulation signal. The newly developed double-cathode photodetector (DCP) performing the opto-electronic correlation and the all-passive read-out circuit are implemented on a single chip. By using the DCP the fill factor is greatly improved compared to K. Oberhauser et al (2006). For an optical active area of Apd = 115times120 mum2 a very high fill factor of etafill = 67 % is reached. The sensor is capable of measuring distances up to sd = 6.2 m with an optical transmitted power of Popt = 1.2 mW at a wavelength of lambda = 650 nm.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126483555","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 leads to the problem of errors-in-variables (EIV). The effectiveness of one particular EIV method, namely the bias compensation least squares estimation method, is analyzed, with simulations carried out on a first order bilinear system. It is shown that the use of perturbation signals with carefully selected harmonic properties can lead to significant improvements in the estimation of the best linear approximation of the system. In particular, a spectrum that is sparser but having a larger magnitude at the nonzero harmonics is found to be more robust towards the effect of noise.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126427731","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 corona discharge is so weak that the amplitude of the current is in the level of muA and its frequency ranges from DC to MHz. An optical micro-current transducer used for the measurement of this current is described in this paper based on an amplitude modulation principle. It uses a fiber optic link for data transmission from the remote module (high voltage side) to the local module (ground potential side) and a battery for supplying power to the electronic circuitry of the remote module at high voltage side. The uncertainty of the transducer is estimated to be less than 0.5% in ratio and its response frequency range is from DC to several MHz.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128146417","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}

In some cases, e.g. during the process optimization, the real-time measurement of mass and temperature is important to monitor drying rate and to prevent product damages because of unsuitable temperatures. In these cases sensors and measurement instruments have to be installed inside the vacuum chamber of the freeze dryer, where temperature and pressure can reach -60degC and 1 Pa respectively. This paper deals with the problems related to the measurement of mass and temperature inside freeze dryers and describes a measurement system that has been specifically designed to monitor lyophilization processes.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125481984","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}

In fact, nearly everyone of the actual available systems use proprietary embedded software to perform measurements, because only the manufacturer knows the internal hardware architecture and as servers exchange information. Moreover, those systems are not able to share information in a free way, because of using different implementations and protocols. The main goal of this paper is to present an implementation of a distributed measurement system, based on the web service approach. The proposed system is based on a freeware widely utilized technology, the Gnutella network, to route and share information adopting a low-cost hardware architecture. Gnutella, like most other peer-to-peer (P2P) applications, builds a virtual network with its own routing mechanisms at the application level. The implemented topology of this overlay network and the routing mechanisms have a significant influence on the application properties such as performance, reliability and scalability. The Gnutella architecture gives the possibility to create a monitoring network in which the clients are all connected without any user operation. In this paper, the authors describe the implemented Gnutella-based distributed measurement system and the architecture of the implemented prototype of low-cost smart web sensor.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131929231","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}

Batteries need to be replaced and hence can become the largest and most expensive part of the system. On the other hand, our environment is full of waste and unused energy such as that coming from the sun or mechanical vibrations. As a result, commercial energy harvesters are increasingly available to power autonomous sensors. This work presents and analyses commercial energy harvesters currently available. First, environmental energy sources are classified and described. Then, energy harvesting principles are described and some guidelines are given to calculate the maximum power consumption allowed and the energy storage capacity required for the autonomous sensor. Finally, commercial energy harvesters are evaluated to determine their capability to power a commercial autonomous sensor in some given circumstances.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134413705","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 influence of signal distortion and noise has already been the subject of many contributions; an analysis of phase noise, its effect on test results and possibilities of its suppression or correction are the subject of this paper. The validity of phase noise analysis and of proposed methods is also demonstrated on experimental measurements.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133927164","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}
