The reason is that they are simple in construction, easy to use and relatively inexpensive in comparison with tools such as EEG, MRI and FMRI that can be used for research purposes without much investment. Among the various optical sensors available, the photoplethysmographic sensors that are capable of measuring the blood volumetric changes in subcutaneous vessels are used in present study. Objective is to diagnose different parameters like heart rate, blood pressure, respiratory rate, with the help of reflectance type PPG sensor. Real time PPG signal is captured from the sensor and with the help of microcontroller and RS 232 serial communication, the real time acquisition of PPG signal is observed on MATLAB. Detailed analysis of frequency spectrum of PPG signal shows a cardiac peak around 1Hz corresponding to 60 pulsations a minute and respiratory peak around 0.25 Hz corresponding to 15 inspiration/expiration cycles per minute. After the analysis of PPG signal, all the parameters are calculated and with the help of graphic user interface (GUI), all the parameters can simultaneously be seen on GUI window.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85910738","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}

Resonant gate transistors were first demonstrated as a means of getting high Q devices [1]. The advantages of transistor based transduction as compared to the capacitive detection have also been demonstrated [2,3]. The behaviors of SGFETs have been studied using equivalent lumped parameter modeling methodology [4–7]. Numerical simulations involving “hybrid” FEA coupling between two different tools, ANSYS Multiphysics and ISE-DESIS, with the help of an external Perl script have also been tried [8]. Here ANSYS is used for the coupled electrostatic and structural physics calculations and ISE-DESIS provides the correct boundary conditions for the electrostatic domain using semiconductor physics. Another related study [9] solved the beam equation coupled with the Poisson equation numerically using finite difference and Newton Raphson method. Our work presents an easier modeling and analysis of a suspended gate MOSFET in COMSOL, successfully demonstrating a solution of a moving gate type device. In our analysis, we consider the air gap as a deformable continuum and we report the standard Id-Vg characteristics of the transistor. Commercially available packages such as ISE-DESIS specialize in only fixed gap analysis wherein air is also modeled as a material with a known permittivity. In such an analysis the capacitor formed due to the air gap remains fixed. We demonstrate here that this analysis can be easily carried out in COMSOL using its multiphysics features. Using two dimensional analysis involving structural mechanics domain, moving mesh ALE, convection and diffusion, and the electrostatics domain, the effect of moving gate and hence the moving air gap can be modeled and analyzed.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77832512","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}

Recently, advancements in the device and packaging technology such as Analog Front End (AFE), FPGA and ASIC has enabled on-board designers to develop space worthy, high reliability miniaturized hardware meeting the functional and performance requirements. HMC, SIP, 3D packaging technology etc. can further miniaturize the hardware by embedding dice, devices, active and passive components. 3D packaging technology, which is ESA qualified, allows us to integrate packaged devices and printed circuit boards (PCB) with high reliability vertical interconnections. It is possible to migrate from existing PCB designs along with the same bill of material to 3D packaging technology. A development of miniaturized camera module consisting of 4K elements linear detector, detector drive electronics, analog video processing and digitizing electronics, timing and control logic along with serial data output has been carried out for space use using 3D packaging. Brief details of this camera hardware, development steps and realization challenges along with test results are given in this paper.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80333728","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}
