Each finger movement is transduced in one type of prosthesis action, joint rotation, and compliant hand by the middle and index fingers, respectively. In this paper are presented preliminary results regarding the prosthesis assembling and tests with pre-acquired and processed data.

In this work, FDR was expanded to maintain anchor rods. Such rods are buried in soil to provide fixed support for multiple buildings (such as power transmission towers). Transmission line theory is used to detect and locate wear in metal structures. A high-frequency connector called MDSC (Microwave Device for Support and Connection) was previously designed to allow electromagnetic waves to propagate on two rods, one of which is the rod under test. Tests were performed by applying FDR to two rods manufactured with different fault locations. The results show the efficiency of using this technology to perform preventive maintenance and effectively locate failures on the rods. In addition, the measurement results have been reproduced in a simulation software. Both measured and simulated results are compared with each other and the difference between them is up to 11.24% of Voltage Standing Wave Ratio (VSWR).","PeriodicalId":124570,"journal":{"name":"2021 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116533050","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 drive test mode allows to increase the measurement capacity in a vast territorial extension, which has been adopted by the National Telecommunications Agency in Brazil. The simulation results demonstrate that there is an overestimation of the measured levels when close to the vehicle's metallic structure. This indicates that the mobile measurement method is conservative in the assessment of human exposure to radio frequency electromagnetic fields.","PeriodicalId":124570,"journal":{"name":"2021 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116535739","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}
