The wireless EM harvester consists of a Printed Circuit Board (PCB) planar antenna and RF to DC circuit using schottky diodes and passive components for impedance matching. Measured and simulated S11 and gain for various resonant frequencies of the multiband antenna are presented. Average open circuit voltage and efficiency of the broadband RF to DC circuit from 800 MHz to 2 GHz is 0.45 V and 8% respectively at -0 dBm input power. It is shown in this work that using a single multiband antenna and broadband RF to DC circuit, the performance of an EM wireless harvester can be enhanced by harvesting energy from different ambient EM frequencies in its operating band at the same time.","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"22 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":"133125482","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}

Pairing this with wireless technologies in particular enables cost-efficient retrofitting of existing buildings. To this end, we introduce an overall system architecture and a residential services gateway essential to it, detailing design considerations aiming for extensibility, cost efficiency, and low power consumption. The system enables both local and centralized services. We also describe how these concepts and their implementations find a first application in an ongoing larger-scale R&D project.","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"199 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":"130043365","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 both cases, the device performance depends strongly on the electronic properties of the tubes. Methods for tuning the electronic structure and especially the band gap are highly desirable. A computational study of cobalt decorated CNTs, by means of density functional theory, reveals that very few cobalt atoms can have a significant impact on the electronic structure, turning semiconducting CNTs into the metallic state. This is further verified by quantum transport simulations. The influence of different amounts of cobalt is also investigated.","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"12 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113979549","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 images obtained by a synthetic aperture sonar (SAS) are segmented into highlight, background and shadow regions for the purpose of shape feature extraction, which requires highly correct and precise segmentation results. The EM method of Sanjay-Gopal et al. is improved by using the gamma mixture model. Moreover, an intermediate step (I-step) based on DST is introduced between the E- and M-steps of the EM to consider the spatial dependency among pixels. Two combination rules of DST are adopted and compared, i.e. the Dempster rule and the cautious rule. Finally, numerical tests are carried out on both synthetic images and SAS images. The results are compared to those methods from the literature. Our approach provides segmentations with less false alarms and better shape preservation.","PeriodicalId":425823,"journal":{"name":"International Multi-Conference on Systems, Sygnals & Devices","volume":"58 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":"134635025","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 transmittance of CdS thin films was measured for different light wavelengths. The films exhibited high degree of transmittance in the infrared region and sharp falling absorption edge at nearly 500 nm. On the other hand Cu2S layer has a maximum transmittance at 700 nm wavelength. It was also noticed that the sample exposed to 100°C annealing gave maximum photocurrent (1.5 mA) but lower open circuit voltage (0.365 V). A maximum open circuit voltage (0.4V) and lower short circuit current (1.3 mA) was produced by the sample exposed to 400°C annealing. The variation of Voc as a function of aging time for the Cu2S/ CdS films under repeated cycles of illumination and annealing is investigated. The results show clearly that the annealing improves the fabricated Voc samples and Voc. increases considerably with time. A technique involving heat treatment, washing and depositing a very thin layer of copper on top of the solar cell has been employed to improve the cell efficiency.","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":"134264067","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}

More information and features about the environment are required whenever the tasks are more complex and multifarious such as storage and retrieval tasks which are spread everywhere, for example in libraries, factories, warehouses, pharmacies, supermarkets and etc. In this work it is suggested a robot system to store and retrieve inaccurately placed objects according to their alphabetic/numeric codification system. The vision system will detect the objects' position and orientation and will analyze the alphabetic/numeric coding system using SIFT algorithm. After that the system will describe how it will grasp the objects by combining the vision and force feedback.
