bed control system for physically impaired using pressure sensors

Hi, I don't have an abstract, this project is for physically challenged people, to turn around in sleep without waking up any help, so I m trying to use pressure sensors, so that autmatically bed could change a persons [login to view URL] this project out main aim is to tilt the bed depends on patient motion according to patent bed motion our system have to find the pressure on the side of bed while he is moving on the bed... pressure sensors will calculates the pressure of patient here we are using limit switches as a pressure calculating units this limit switches sends the data to micro controller and microcontroller will turns the motor by using hbridge module
