bangalore the third year students of computer science and electronics communication of university visvesvaraya college of engineering uvce bagged the award in analog devices anveshan 2012 contest akshay kumar b u gowrishankar a and samhitha m r working under the guidance of prof b k venugopal came up with a device that can control the human brain brain controlled bionic ear bcbe the brain can be in any one of the four states sleep alert relaxation and meditation transition from one state to the other can be achieved through the bcbe device which works on the idea of mapping audio signals of corresponding frequencies the brain generates signals corresponding to its state hence when mapped with frequencies of other state the brain goes into a new state from the present state this interface device to the brain can be used to get a patient back to normal from anesthetic state sleepy drivers can use this to get rid of sleep filters unwanted noise signals in any range of frequencies and many more exciting applications claimed the students this project was done as a part of anveshan 2012 which aimed at designing an innovative technological solution to address growing system level challenges faced by the world using adi components
