Equations of the converter behavior are presented, and show their use for estimating temperature and thermal radiation. The influence of sensor parameters in the signal to noise ratio of the system are also presented. Simulation and experimental results are showed too. In this A/D converter, the measured variable is directly converted to digital by eliminating the classical stage of signal conditioning which the measurement variable is firstly converted to the electrical domain and then is made an analog to digital conversion. It is also shown that the output binary code has a linear relationship with the measured variable throughout the measuring range. The major contributions of this paper are: the proposal for a thermal A/D converter simplified topology and a theoretical deduction of the static behavior of the converter that relates the sensor parameters and the obtained result with the measured variable. This approach can be useful as a basis for a smart A/D converter design in any temperature or thermal radiation range allowed by the sensor and can be extended for measuring fluid velocity.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123669288","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}

Wireless sensor networks (WSNs) benefit from both synchronization and localization as it enables the sensor node to fuse measurement data with temporal and spatial information. The lower communication layers of WSNs are often based on the IEEE 802.15.4 standard, whereas only for Ultra-wideband (UWB) timestamping and ranging abilities are specified. The Chirp Spread Spectrum (CSS) physical layer, recently introduced into IEEE 802.15.4-2011, is another promising modulation scheme for highly accurate timestamping. This paper presents a timestamping receiver architecture for 802.15.4 CSS based on a Delay-Locked Loop and subsample interpolation (chirp generation) using the CORDIC algorithm. This architecture generates arbitrary subsample- and frequency-shifted chirp templates on the fly and therefore does not require large correlation filters. Simulations of the timestamp performance show that the proposed architecture offers equal performance as post-correlation delay estimators, yet with a significantly reduced amount of multipliers. This facilitates the implementation of precision clock synchronization and localization into low-power wireless sensor nodes.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122758812","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}

Because the TDR method has the worse signal-to-noise ratio (SNR), it is difficult to detect soft cable faults (frays, chafes, and joints) which cause tiny impedance changes in the cable and small reflected signals. The FDR method has better SNR than the TDR method because of using a power signal as incident signals and signal processing for cable fault location. However it is difficult to identify the type of cable fault. A new method using impedance spectroscopy (IS) for cable fault location is described in this paper. With the new method not only cable fault can be located, but also the type of cable fault can be identified. The periods of cable's impedance can locate hard (open and short circuits) and soft wire faults (frays, chafes and joints). The angle of the cable's impedance in low frequency domain can identify the types of the faults. A signal processing algorithm is developed to accurately locate the cable fault and provide enhanced resolution and range. The details and test results with IS system on realistic twisted pair lines are described. Only one single fault is detected in this work.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121871643","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}
