Its computational complexity is independent of the environment size and it works even when sensing only one landmark at a time, allowing its operation in landmark poor environments.

The ILFD circuit is realized with a differential CMOS LC-tank oscillator with an injection MOS. The proposed design accomplishes wide tuning range frequency by using binary weighted switched varactor in addition to a linearly varying varactor. It can be applied for multi-standard wireless applications. The tuning range of the ILFD carrier frequency is from 1.2 to 1.75GHz. At the injection signal power of 0 dBm, the locking range is about 1.1 GHz from the incident frequency 2.4 to 3.5 GHz. The phase noise of the locked output is -123.4 dBc/Hz at 1 MHz offset frequency. The power consumption of total circuit is 22.98mW.

Water is not unlimited resource especially running and fresh water. The research, included in vast framework, intends to render some outcomes regarding the application of leak detection in pipelines. The kind of pipeline considered in this research is a zigzag one with bends. Leak detection speed and its magnitude are most significant because they allow to save money and time. Because of the zigzag configuration and the small section, it is not easy to do that for this case. This research proposes a comparison between two important techniques used for computing and detecting leakage in pipelines. They are FDM (Filter Diagonalization Method) and impedance method.","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124170047","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 addition to proprietary solutions different standards have been established: WLAN, Bluetooth® and ZigBee™. To improve the EMC parameters of radio modules symmetrical topologies using differential signals have been introduced. Since the majority of test and measurement equipment has single ended inputs with coaxial connectors (except VNAs) there is a gap between measurement, test equipment and application. Based on the development of a load board for a ZigBee transceiver by Atmel® the way of solving this conflict will be shown. The focus is set on the issues of RF transmission lines including the step from planar to coaxial structures, RF contact systems and calibration and de-embedding procedures. The influence and frequency response of the RF wiring to the tester instruments has been reduced. The realized accuracy of RF parameters measured on the load board is presented. Applications for these RF ICs are wireless data transmission in general and wireless sensor networks [11].","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125719363","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}

Stain sensors based on CNTs can overcome several limitations of the existing conventional sensors, including limited monitoring locations and separation from the structure that is being monitored. Many deposition methods were applied to deposit CNTs on substrate; inkjet technology among others will possibly turn out as a fast and flexible manufacturing method for CNT-based sensors. We report about a wireless passive strain sensor made by inkjet-printing of CNT dispersions on flexible substrates. According to the radio frequency identification (RFID) principles, a square planar coil was patterned using inkjet orienting technology on a flexible substrate (Polyethylene terephthalate - PET) in order to measure strain wirelessly [6, 7]. Several settings of printing were investigated and optimized. Coils of different design parameters including variation of the number of windings, inner diameter, outer diameter and number of printed layers were manufactured using inkjet printing. The investigation of the readout mechanism of the sensor was done by applying the electrical impedance spectroscopy (EIS) analysis. By measuring the change in the complex impedance of the coupled coil, the changes in the resonance frequencies of the sensors were detected wirelessly. The change in the bandwidth is considered to be the main effect of the sensor under strain.","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125921510","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}
