The locating system is generally composed of tags, readers, and a location engine. Tags are attached to the object and obtain information via communication with readers that are installed around the tags. The engine continuously attempts to estimate the location of tags by using the obtained information. However, if we attempt to apply this common locating system to a port environment for logistics automation, the system performance is degraded because there are many steel obstacles that cause interference in the RF communication and measurement. In this paper, we propose a two-step approach for location estimation in harsh port environments. We divided readers into two types (fixed and mobile readers); hence, the location method operates in two steps for efficient wireless communication and precise measurement. We implemented all the system components and installed these at a real port for evaluation. The communication and estimation success rate is more than 50% better than that of the existing general locating system, and the location precision is substantially increased.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127219110","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}

For use in a medical context, special requirements and limitations must be taken into account, especially regarding accuracy, reliability and operating range. In this paper we present an experimental setup for a medical navigation system based on RFID. For this we applied a machine learning algorithm, namely support vector regression, to phase difference data gathered from multiple RFID receivers. The performance was tested on six datasets of different shape and placement within the volume spanned by the receivers. In addition, two grid based training sets of different size were considered for the regression. Our results show that it is possible to reach an accuracy of tag localization that is sufficient for some medical applications. Although we could not reach an overall accuracy of less than one millimeter in our experiments so far, the deviation was limited to two millimeters in most cases and the general results indicate that application of RFID localization even to highly critical applications, e. g., for brain surgery, will be possible soon.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131962567","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 a novel approach for incorporating solar harvesting capability into existing passive RFID tags without increasing the parts count or changing the tag assembly process. Our approach employs the tag's antenna as a dual function element in which the antenna simultaneously harvests RF energy, communicates with the RFID reader, and harvests solar energy for auxiliary power. This is accomplished by using low cost, printable photovoltaics deposited on flexible substrate to form part of the antenna's radiating structure. Several prototype UHF RFID antennas are demonstrated using commercially available thin film, amorphous solar cells. To quantify the improvement in tag performance, Intel's WISP was used as an initial test vehicle. The effective read range of the tag was increased by six times and exceeded the reader's sensitivity limitations. Additionally, the new antenna allowed for sensing and computing operations to take place independent of the RFID reader under typical office lighting conditions.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122623362","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}
