The pitch system of a wind turbine has to fulfill two functions: Limiting the turbine power during strong wind conditions but also braking the turbine via pitching into the feathering position. The second task is safety critical and therefore the pitch system must be equipped with a backup storage in order to react autonomously under grid failure conditions. State of art for electrical pitch systems are lead fleece accumulators due to big experience and cost attractiveness of this technology. Compared with standard DC machines, compound types combine the advantages of a shunt and series machines for direct battery connection: They are naturally able to resist low and regenerative torque conditions like shunt machines by also able to provide a torque even if the battery voltage is low e.g. in case of defect battery cells. But compound machines can show an unstable behavior if the machines changes from motor to regenerative operation during direct powered emergency drive. If this effect appears, the machine generates a dynamic regenerative current peak that causes electromechanical transients stressing the whole pitch drive train. In order to analyze and understand this phenomena a detailed dynamical model of the DC compound machine was developed.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"26 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114096169","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}

These materials can be used to design and develop sensors, actuators and multifunctional systems with a large number of applications for developing medical devices (for both surgery and implants). On the other hand, Bruxism is a health problem consisting on grinding or tightly clenching the upper and lower teeth, and both phenomena lead to wear of the teeth and produce a noise during the night that is sufficiently loud to disturb the sleep of anyone sharing the bedroom. The tension produced also causes problems in the muscles, tissues and other structures surrounding the jaw, ear pain, headaches, lesions to the teeth and disorders in the jaw joints. For an early, rapid, effective and economical diagnosis of bruxism, we propose the use of instrumented splints based on the use of active materials that detect and record the intensity and duration of interdentally pressure episodes. This paper introduces the design, manufacture and testing of using instrumented splint for bruxism detection. The contribution of this work is basically focused on using piezoelectric polymeric sensors, taking advantage of their reduced thickness, and avoiding the alteration of the patient's bite. In addition, the system allows a quantitative assessment of intraoral pressure that consequently allows the diagnosis of bruxism behaviour at an early stage, aiming to perform corrective actions before irreversible dental wear appears. The first trials performed allowed to demonstrate the feasibility of the system, which also includes wireless communication capabilities for improving on telemedicine tasks.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122913606","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}
