This architecture leads to a reduced element system, without any coupling transformers, phase loop, mobile screens or mobile magnetic cores. The model is based on simplified equivalent models but takes into account data extracted from finite element software concerning the energy transfer between the inductor currents and the piece to be heated. It is implemented in a versatile power electronic software, PSim. An optimization procedure calculates the optimal supply currents in the inverters in order to obtain a desired heating of the work piece. The simulated and experimental results are compared in open-loop and closed loop. The paper ends with a current control method which sets RMS- inductor currents in continuous and digital conditions.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134374643","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 decoding masks are used for the key for decryption. Use of physical keys are secure against cyber attacks including computer virus and spy ware. In order to secure the physical keys against theft, the number of decoding masks is increased. Code sets have been constructed to encrypt a binary image so that information on a secret image is shared between a displayed image and multiple decoding masks. The key is shared between plural users. The secret is represented only when all shared masks are overlaid in front of the displayed image. Optical decryption and limitation of the viewing zone have been demonstrated with a displayed image shown on a liquid crystal display (LCD) and decoding masks in front of the LCD. The viewed image is secure against prying eyes behind the viewer.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129667352","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}

Due to heating effects, harmonic currents that are injected by customers can inhibit the operational effectiveness of such applications. This paper describes a method for indentifying the originating locations of feeder level harmonics with the use of THD measurements retrieved remotely from capacitor banks and a single harmonic spectrum analysis. The authors utilize a simplified distribution system model to perform current injection calculations to match the measured feeder level distortion that is identified from remote monitoring. The spectrum analysis measurement is utilized to determine the individual harmonics of the THD measurements and to develop harmonic source parallel impedances. The process was applied to an existing Volt/VAr application that was frequently experiencing 9% voltage THD.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126197836","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 key concept underlying the techniques is to display useful information for human activities that is imperceptible to the human visual system, even though it can be read out by other means. Various methods of making information imperceptible are described. Typical examples of these are those that use spatially or temporally imperceptible patterns. These techniques have great potential to enable attractive new applications to be created. Security is presently the most interesting application because it can conceal information and reveal it to select individuals; however, other promising applications are being studied extensively in various fields such as ubiquitous computing and augmented reality.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117348794","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 technology accurately locates workers around mining machines in real time. With the accurate locations of the workers around the equipment being known, their safety status can be evaluated. If a worker is located dangerously close to a machine, the machine can be partially or completely disabled to protect the worker from striking, pinning and entanglement hazards according to pre-defined logic. The technology is particularly applicable to mobile underground mining machines which offer difficult safety challenges in that operators generally work in close proximity to these machines in very restricted spaces. With use of the intelligent proximity detection system, nuisance alarms and failures to alarm are also expected to be sharply reduced. An effective proximity warning and action zone scheme is necessary for safe implementation and will improve the acceptance of a magnetic proximity detection system by underground workers.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133004726","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 Streamline-upwind/Petrov-Galerkin (SUPG) stabilized finite element method is proposed to solve the air governing formulations in the region between the cables and the retaining tunnel in the underground power transmission system. In thermal analysis, a nonlinear-coupled electromagnetic-thermal model of underground cables and the radiation heat exchanges between external cables surface and internal tunnel surface is proposed. The analysis reveals that the convection induced heat exchange is much stronger than the conduction induced heat exchange in the air between external cables surface and internal tunnel surface. At last, Newton-Rahpson iteration method is used to evaluate the cable ampacity.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133552995","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}
