Some markers are mounted on the vehicle so that the Vicon system can track it. The markers arrangement is stored once in the Vicon system. In practice, after a few flights the markers' configuration may be slightly altered causing offsets in the measurement of the true attitude of the quadrotor. The Vicon system itself may also measure the vehicle's attitude with some errors in the angles due to small displacements of the cameras and a long period of use without recalibration of the whole system. Since it would be very tedious and cumbersome to recalibrate the whole vision system and making sure that the markers arrangement is still valid before every flight, a simple method has been developed to accommodate any offset in the attitude measurements. Better flight performance is obtained using the method presented.","PeriodicalId":133325,"journal":{"name":"2009 IEEE International Symposium on Industrial Embedded Systems","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127397138","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}

End-to-end delays of controls must be estimated using incomplete and aggregate information on the computation and communication load for ECUs and buses. We describe the use of statistical analysis to compute the probability distribution of Controller Area Network (CAN) message response times when only partial information is available about the functionality and electrical architecture of a vehicle. We provide results on simulation as well as trace data to show that our statistical inference can be used for predicting the distribution of the response time of a CAN message, once its priority has been assigned, from limited information such as the bus utilization of higher priority messages.","PeriodicalId":133325,"journal":{"name":"2009 IEEE International Symposium on Industrial Embedded Systems","volume":"61 20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129975515","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 multi-layer task model based on the concept of Virtual Sensors (VS) to improve architecture modularity and design reusability. In our pilot application of gait parameter extraction, VS are abstractions of components of BSN classification systems that include sensor sampling and processing tasks and provide data upon external requests analogous to the function of physical sensors. The paper presents an extension of the SPINE Framework including a new buffer management scheme that facilitates the VS implementation.","PeriodicalId":133325,"journal":{"name":"2009 IEEE International Symposium on Industrial Embedded Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126457093","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}

Resource-economic use of information is of primary concern in issues of control under communication constraints. We need to emphasize more on informational aspect which has got direct relation with uncertainties in terms of Shannon Entropy and Mutual Information(MI). Disturbances due to communication channel-induced noises and limited bandwidth are causing the information packet-loss and delays resulting in degradation of control performance. CG is a measure of control performance and Fisher Information (FI)is a measure of accuracy of estimation (which needs to be done in uncertainties caused by packet-loss and delays of the network).","PeriodicalId":133325,"journal":{"name":"2009 IEEE International Symposium on Industrial Embedded Systems","volume":"43 8 Pt 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125673655","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}

It is shown that the unfair allocation of communication resources is an unavoidable part of LonTalk operation in most load scenarios. Unfairness in accessing the channel results in a reduction of the bandwidth available to particular nodes. On the other hand, the channel access unfairness increases the mean channel utilization. There is a tradeoff between the access unfairness level and fairness recovery time: the possible inequality in sharing the bandwidth is greater for the light channel load but the fairness recovery time is then faster. Fortunately, the predictive p-CSMA unfairness has not tendency to escalate but is stabilized by the mechanism of a negative feedback.","PeriodicalId":133325,"journal":{"name":"2009 IEEE International Symposium on Industrial Embedded Systems","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122306084","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}
