The photodiode arrays were built on 75-mum thick single Si dies. The element size varied from over 1.5 mm to 200-mum with the gaps (dead spaces) between adjacent elements as small as 25 mum. The most pronounced features of the arrays described here include very small AC and DC crosstalk very low leakage currents, high shunt resistance, very fast signal rise time, and good photo-response linearity with radiation flux. The crosstalk depended on the dead spaces between pixels but was always better than 0.1% for the arrays with close to 25-mum gaps and better than 0.01% for arrays with over ~50-mum gaps. The photo-sensitivity linearity was found to be better than 0.01% within the spectral range from 450 to 1000 nm and in the range of input light fluxes above ~100 pW/pixel. For lower light fluxes, the non-linearity of the photo-sensitivity was hindered by the noise current of the array pixels and different methods should be applied to provide measurements with an accuracy of better than 0.1%. This work also gives theoretical estimations for the detectivity limits and sensitivity linearity characteristics of the arrays and compares them with those for the conventional arrays used in X-ray imaging systems.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134507166","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 key performance measures is the network's ability to route measurement data from the sensor nodes to the destination node(s). This paper introduces a general framework with which worst-case routing performance of different sensor networks can be evaluated and compared. Our method can either be used as a design optimization tool, or a decision making tool to select and price contending sensor network designs and applications.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134184683","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 method concept is to apply magnetic suspension bearing to a turbine flow meter and thus improve the measurement performance. Under design conditions, the turbine flow meter based on magnetic suspension bearing (MSB) has better linearity and repeatability than the one with ordinary bearings. Test results show that the lower flow limit can be significantly reduced with MSB, which results in a remarkable improvement of test range from 1:10 to 1:50. It is also noticeable that MSB turbine flow meter can work with acid, alkali or corrosive media without the need of stainless steel sealing protection for the magnet.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130286420","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}
