An instrument network based on ZigBee has been set up for investigations. The network had a transmission range of up to 120 meters between the nodes under line-of-sight conditions. The range could be extended by multi-hop operations and utilizing self healing capabilities of the network. It is found that ZigBee based instrument networks are robust but susceptible to interference from other networks operating at the same ISM frequency band, such as WiFi and Bluetooth.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126561254","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}

An important branch of materials to be investigated for this purpose are the semiconducting metal oxides. This work uses titanium monoxide thick films in conjunction with an interdigitated electrode pattern to produce a conductimetric pH sensor. Its advantages over other methods include simpler construction and it is more economical. It was noted that upon contact with a solution, the resistance of the film increases. No meaningful relationship was observed between the resistance and pH for these devices. When a DC bias is applied to the device, a linear decrease was recorded in the relative changes in current through the device and conductance of the film against increasing pH values. Low frequency AC signals also produce a similar response. However, a slow response time and poor repeatability were also observed.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130092149","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 flow totalizer is designed based on MSP430 single chip microprocessor (SCM) coupled with advanced electronic circuit and software, and developed into an intelligent head with multi-functions and digital display. Both theoretical and experimental results show that the intelligent flow totalizer has favorable performance with low power consumption and high accuracy. Compared with similar products, this design is characterized with simple hardware structure, powerful software functions, high reliability and low costs. The meter with this design can work at a temperature as low as -30degC, and has a strong anti-jamming capability.

Knowledge, including shared situation awareness of the battlespace and shared understanding of commanders' intent, enables the warfighter to self-synchronize, leverage available resources, operate more effectively in accomplishing mission goals. The networked communications infrastructure that facilitates the NC operations is referred to as the Command, Control, Communication, Computer, Information, Surveillance, and Reconnaissance (C4ISR) networked communications. Our network design methodology was based on a layered decomposition approach in which key enabling components were optimized jointly in all layers to satisfy the C4ISR needs. The network design methodology can help transforming the required C4ISR needs into operational capabilities such that a warfighter can obtain/share the required awareness in advance and enable timely coordinated action at a distance.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126746190","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 target application to the human gastrointestinal (GI) organ is presented, showing the importance of the method in accessing a specific site for drug administration or for extracting fluid or tissue samples for biopsy and similar medical investigations. Unlike other commercially available solutions that are fraught with invasive procedures our method interfaces with wireless technology to provide non-invasive real-time acquisition of intestinal physiology data and also relay information about the object's whereabouts at all times during the entire period of diagnosis. The system consists of a miniature RF transceiver embedded in the GI tract and a set of receivers positioned external to the body. RF signal is transmitted at 433MHz to achieve half duplex communication between the transmitter and receiver. The frequency shift keying (FSK) modulation scheme was adopted to ensure a reliable and high-speed digital RF link. Undoubtedly, the novelty of the method will foster a strategic marketing advantage by virtue of the solution's ambulant nature targeted at patients suffering from intestinal disorders or irritable bowel syndrome (IBS).","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115272492","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 have developed a new symmetric monotonic regression (SMR) technique for predicting data at one sensor using data from another sensor or a set of sensors that simultaneously guarantees isotonicity and minimizes an arbitrary form of error for predicting stream X from stream Y and vice versa. Using a simple and fast algorithm, we also developed a lower bound regression (LBR) approach for evaluating the achievable accuracy of regression between the readings at two sensors. SMR often performs very close to the lower bound on a set of collected real-life sensor data. We show how LBR barrier can be outperformed by conducting prediction using either data from multiple sensors or by considering information extracted (multiple consecutive time samples) of the explanatory stream. The effectiveness of SMR is demonstrated on a sensor node sleeping coordination problem by reducing energy consumption by more than an order of magnitude with respect to the best previously published technique.","PeriodicalId":137779,"journal":{"name":"2007 IEEE Sensors Applications Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130108211","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}
