It allows the user to communicate with a computer/external device through the process of thinking. Functional near-infrared spectroscopy (fNIRS) is a relatively new non-invasive optical imaging modality that can be used to measure cortical brain activities. The main advantages of using this technique are relatively low cost, safety, portability and wearability. In this paper we propose to apply fNIRS to measure different brain activities during thinking task and body motion task. For thinking experiment the human subjects were asked to solve simple arithmetic calculations. For the body motion task, the subjects were asked to tap finger after regular intervals of time. Continuous-wave imaging system (DYNOT: dynamic near-infrared optical tomography) was used to image each subject's prefrontal cortex during the arithmetic task and motor cortex during the finger tapping task. Our results of fNIRS signal analysis showed different patterns of hemodynamic response for the different tasks that can be used to recognize the brain tasks. Using Fisher's linear discriminant analysis we were able to distinguish clearly between the different brain activities with an average accuracy of above 80%. This idea can be used to directly control a robot through thinking process or through movement of the body using fNIRS.","PeriodicalId":105350,"journal":{"name":"2012 International Conference of Robotics and Artificial Intelligence","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125089666","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}

They spread rapidly and indiscriminately obliterate all things in their path. Fighting fires entails undeniable danger to life and the majority of suppression systems used to control them is at a broad-spectrum or macro scale. We present the design, fabrication, and testing of an autonomous fire extinguishing system. This system provides a unique solution to the problem of fires and their destruction by targeting the initial ignition of the fire and suppressing it before it starts to increase in intensity and range. The presented system detects, targets, and extinguishes a fire within a working space by using heat sensors, a flow control system, servo motors, and a water extinguishing gun. The system scans its workspace through motors and uses thermopile arrays to detect heat concentration gradients in its range. After the detection of the fire, the system then locks on to the target by extrapolating its location. Efficiency of the system, suppression accuracy, response time, power consumption, and work space area are also documented and presented in this paper. Future considerations and recommendations are highlighted to advance the system's design, efficiency, and scope. This is an indigenous solution to fire fighting in world and it is to make environment a healthier and safer place for the future.","PeriodicalId":105350,"journal":{"name":"2012 International Conference of Robotics and Artificial Intelligence","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122755278","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 objective is to design an efficient Vehicle Number Recognition System & to implement it for automatic toll tax collection. The system detects the vehicle first and then captures the image of the front view of the vehicle. Vehicle number plate is localized & characters are segmented. The system is designed for grayscale images so it detects the number plate regardless of its color. Template matching technique is used for character recognition. The resulting vehicle number is then compared with the available database of all the vehicles so as to come up with information about the vehicle type & to charge toll tax accordingly. The system is then allowed to open road barrier for the vehicle & generate toll tax receipt. The vehicle information (such as passing time, date, toll amount) is also stored in the database to maintain the record. The hardware & software integrated system is implemented & a working prototype model is developed. Experiments show that system successfully detects and recognize the vehicle number plate of real images of Pakistani vehicles.","PeriodicalId":105350,"journal":{"name":"2012 International Conference of Robotics and Artificial Intelligence","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128460042","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}
