A centered transmitter emits a broadband ultrasonic impulse which is reflected by obstacles in the environment. Reflected waves, if propagated back to the sensor, are then received by four identical ultrasonic microphones. These signals are used to provide polar- and azimuth information based on time difference of arrival and in addition, by using a novel method presented in this paper, sub wavelength accurate distance measurements are possible as well. The used algorithm does not rely on the actual shape of the signal but only on its statistical properties. This is a great achievement because commercially available broadband ultrasonic transducers are typically piston membrane types which exhibit a strong frequency dependent radiation pattern. If measurements are performed outside of the main lobe, not only the signal amplitude is greatly reduced requiring algorithms capable of dealing with a low SNR but also the phase of the signal is affected yielding simple pulse compression techniques useless. The article includes a description of the problem, a comparison to existing systems, a theoretical treatment of the system configuration and experimental results demonstrating the performance of our sensor.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132641748","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}

However, usage of ROMs in high-performance circuits has poses substantial challenges, mainly because of its inability to run at-speed tests and high area overhead due to its prohibitively large size. An alternative to ROM utilization is the use of LFSRs. But, the computation time of the LFSR based BIST synthesis for large mixed-signal SoC poses a huge challenge. A high-performance computing (HPC) based automated mixed-signal SoC BIST synthesis technique that can outperform the conventional ROM implementation not only with respect to the computation time needed to generate the test vectors or waveforms, but also the BIST hardware required, is presented in this paper. Furthermore, the versatility of the presented LFSR based BIST test vector generator, that allows itself to be used for embedding deterministic patterns for LBIST and storing sinusoidal stimuli or pre-calculated Delta-Sigma modulated bit-stream for analog BIST, is demonstrated.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130729950","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}

Tractable reconstruction algorithm is a crucial and fundamental theme of compressive sensing, which has drawn significant interest in the last few years. In this paper, firstly a novel approach was proposed to improve the original IHT algorithm, which is called Orthogonal Iterative Thresholding algorithm. Compared with IHT algorithm, several simulation results verify its efficiency in reconstructing of Gaussian and Zero-one signals. After that we propose another new iterative algorithm to reconstruct a sparse signal from a underdetermined linear measurements. This algorithm modifies Backtracking-based Iterative Hard Thresholding (BIHT) by adding one atom instead of the simple backtracking step in BIHT, which can guarantee the reduction in residual error. Compared with other algorithms, such as Orthogonal IHT(OIHT), BIHT, Normalized IHT (NIHT), the experiments on Gaussian sparse signal and Zero-one sparse signal demonstrate that the proposed algorithm can provide better reconstruction performances with less computational complexity in each iteration than convex optimization method.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133696927","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 this paper we will briefly describe a viscosity measurement cell utilizing electrodynamic-acoustic resonator sensors and provide a modified design with interchangeable resonator cards, which allow for ease of maintenance of the device and provides higher measurement repeatability. Some basic experiments made with the new resonator cards are presented, which show the clear dependence of the resonance frequency and Q factor on viscosity. In addition, an approach is taken to optimize the magnetic circuit for the measurement cell using finite element simulations and experiments. A temperature dependence comparison is made between straight beam resonators and S shaped (Meander) beam resonators the result of which is the adoption of the S shaped beam design for further investigation. Finally the data processing approach using a curve fitting function designed for low quality factors is briefly described.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133353727","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}
