The ability for the sensors or actuators to have transducer data sheets will allow the \"plug-and-play\" of 1451-compatible sensors and actuators for different control networks. Implementation of an intelligent sensor network testbed is in progress to perform research and investigation of smart sensors, and the investigation and verification of interfacing options from smart sensors with the sensor networking bus. There has been some development and integration of IEEE 1451.1 communication; however, after research of products available that are IEEE 1451 capable, only products relating specifically to IEEE 1451.2 were available in development and starter kits. No products were available that depicted the IEEE 1451.1 standard for communication between the smart sensor nodes of a network. Therefore, a 1451.1 compatible NCAP has been developed and integrated into a testbed. This paper will present the development of the IEEE 1451.1 NCAP-NCAP communication using the LabView 8.2 Programming Language. Furthermore, testing of message conformance and functionality of the 1451 communication on the network has been accomplished.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121430702","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}

Recent studies suggest the molecular mechanism responsible for the translocation of cytochrome c from mitochondria to the cytosol during apoptosis. We hypothesize that mitochondrial injury causes the final release of cytochrome c from cytosol to the bloodstream, which acts as a mitochondrial injury external sensor. Serum cytochrome c was dissociated from large, abundant proteins by acetonitrile precipitation pretreatment and then measured using reverse-phase high performance liquid chromatography (HPLC). For quantification of serum cytochrome c levels, internal standard curves (0.2 to 20 mug/ml) were prepared using rat heart cytochrome c dissolved in serum obtained from healthy pentobarbital-anesthetized rats. Serum samples taken from severe mitochondrial injury animals (heart attack rats and diabetes mice) were measured and shown a dramatic increase in cytochrome c levels compared to healthy animals. Irreversible mitochondrial injury (death) occurred once serum cytochrome c level exceeded 2.0 mug/ml as the average cytochrome c level for healthy animals is reported less than 0.2 mug/ml. We conclude that serum cytochrome c may represent a novel in-vivo external sensor of mitochondrial injury.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127935056","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 multilayered architecture is used. To ensure even higher scalability and lower message size in any particular layer, number of layers is limited to four and each layer is broken into grids. Each grid acts a localized network where data aggregation and lifetime maximization algorithms are being run. In standard sleep protocols like GAF, each grid must have one of its nodes in active state. Our sleep protocol considers one node per grid to be in the idle listening state called the 'doze' state for a fixed interval of time. Thus we propose a multi-state proactive algorithm in the form of the sleep doze coordination (SDC) protocol to lower the duty cycle of each sensor node and maximize the network lifespan with lower power consumption. Node buffers are provided to bring about higher data accuracy and lossless network operation. Thus the node does not have to remain active throughout its 'on' period and its overall lifespan increases for a given amount of energy. Results indicate that near- optimal performance of SDC is achieved when buffer size is large enough to hold 25 data messages. SDC increases network lifetime by approximately 20% over previous protocols like GAF and S-DMAC. This buffered approach to the SDC protocol is called the lossless SDC (LSDC) protocol.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117201425","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}

This paper presents the design, fabrication, implementation and analysis of an array of such muSGIs. The muSGIs are capable of static and dynamic displacement measurements. The muSGIs have phase sensitive micromachined gratings which are actuated by electrostatic force. The muSGIs are fabricated on SOI wafers. The fabricated tunable gratings exhibit the first resonance mode at 48 kHz and a damping ratio of ~0.05. The gratings show sufficient (~400 nm) displacement range for tuning it to high sensitivity position, achieved with 30 V operating voltage range. To actively tune the gratings a novel control algorithm is implemented real-time in a field-programmable gate array (FPGA). It adjusts the position of each grating with respect to corresponding sample, to achieve high sensitivity. Active control scheme is modeled using MATLAB and the performance results show good agreement with the experiments. The control algorithm is successfully used to characterize the tunable gratings and to demonstrate parallel operation of the muSGIs. Experimental results demonstrate a vertical resolution of 0.2 pm over 1 Hz bandwidth.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134268423","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}
