The sensing system consists of two Fabry-Perot (FP) interferometric cavities with pressure movable and reflective diaphragms. The broadband lights return from the two FP type of sensor probes, and they are superimposed in the optical frequency domain. The doubled air gap size is much smaller than the coherence length inversely proportional to the spectral resolution, while the optical path difference (OPD) between two fiber channels is designed much longer than the coherence length. The superimposed intereference fringe shows a sinusoidal and amplitude modulated signal due to the air gap sizes' difference, which is biased by the signals due to the total air gap sizes in the frequency domain. Frequency interval of the low frequency factor is converted into the DP values without any compensation for the unwanted factors, including source power fluctuation and fiber bending losses. Experimental result shows that a resolution is as high as the 0.08 kPa per THz and accuracy as high as 1.0% per full scale.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115819949","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}

A non-balanced (NB) bridge approach was adopted for both resistive and capacitive interfaces, eliminating the need for finely tunable on-chip components to balance the bridge. The shared pre-amp and programmable gain signal-conditioning stages are formed with switched capacitor circuits. Through a carefully designed clock scheme, a sample-and-hold (S/H) function is realized without a dedicated S/H circuit. The effects of op-amp offset and parasitic capacitance at the inputs are suppressed, and undesirable disturbance of the bridge DC point is avoided during resistance measurement. The 0.53 x 0.75mm circuit was implemented in 0.18mum CMOS and requires only 300muA from a 1.8V supply. It has the size and power efficiency to implement a front-end sensor interface system-on-chip with an embedded controller.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117339075","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 orientation chip receives output image of the silicon retina and aggregates multiple pixels in the image to generate a Gabor-like orientation-selective spatial filter. The orientation and spatial frequency properties of the filter is controlled by selecting the pixels to be aggregated using external signals. Multiple orientations and spatial frequency bands were implemented in separate chips that are connected in parallel to the silicon retina to obtain output images tuned to different orientations and spatial frequency bands simultaneously.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121247642","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}

We named this system MOST (MOtion Sensing Technology). The MOST consists of 3 angular rate sensors, 3 acceleration sensors, and a DSP (digital signal processor). The acceleration sensor is a semiconductor type and the angular rate sensor is a quartz type. The sensors have been made by MEMS (micro electro mechanical systems) technology for mass-produced cars. They are good for miniaturization of the sensing unit. Posture angle is generally obtained by integrating the angular rate over time. However, there was the divergence of the posture angle due to the offset output integration. New algorithm was proposed to suppress the divergence of the posture angle with the DSP in real-time.

Iterative algorithms produce better quality images however they can only be used off-line due to intensive computational burden. In the context of computational burden, in this paper we propose a fast noniterative image reconstruction algorithm called on-line directional algebraic reconstruction technique (OLDART) which like its predecessor, directional algebraic reconstruction technique (DART), produces the same quality image but reduces the reconstruction time. The reconstruction procedure of the proposed algorithm comprises of two steps. In the first step, a modified weighting matrix is generated off-line, and in the second step, the matrix is used for on-line image reconstruction in the same manner as the sensitivity matrix in the linear back-projection algorithm is used. In order to assess the reconstruction performance, extensive simulation results are provided for the proposed approach.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127371614","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}

Highest possible phase accuracy and disturbance immunity (air gap and temperature variations, noise) are the primary performance requirements for such sensor systems. An analog signal is generated from a magnetic field sensor and the position information is obtained using state of the art peak or zero crossing detection in the analogue or digital domain. While phase jitter of peak or zero crossings can be minimized by optimizing zero crossing and peak detection methods, these techniques cannot take into account variations of peak and zero crossing positions due to air gap variations. A Decision Feedback Equalizer (DFE) was adapted to remove this systematic error. For this purpose a physical model of the measurement environment (magnetic field) was derived and verified by Finite Element simulations (FEM). With simplifications the model delivered an analytical function for magnetic field calculations, which serve the adaptive algorithm for the DFE.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123408017","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}

Hence, the dynamic image reconstruction algorithm has been introduced to reconstruct the tomogram without the full set of data, in principle even with a single pair of current-voltage data. Although the pre-determined current injection protocol plays an important role in the image reconstruction performance, analyses of the effect of current injection patterns on the reconstruction performance have not been performed rigorously.
