Tongue Drive system (TDS) is a tongue-operated unobtrusive wireless assistive technology, which can potentially provide people with severe disabilities with effective computer access and environment control. It translates users' intentions into control commands by detecting and classifying their voluntary tongue motion utilizing a small permanent magnet, secured on the tongue, and an array of magnetic sensors mounted on a headset outside the mouth or an orthodontic brace inside. We have developed customized interface circuitry and implemented four control strategies to drive a powered wheelchair (PWC) using an external TDS prototype. The system has been evaluated by five able-bodied human subjects. The results showed that all subjects could easily operate the PWC using their tongue movements, and different control strategies worked better depending on the users' familiarity with the TDS.

So protect severe disabled kids we can monitor their activities by wireless camera monitoring system which helps us to keep eye their activities [6] [9] [10]. "

    ABSTRACT: Assistive technologies play a critical role in the lives of people with severe disabilities and help them to lead independent self-supportive lives Persons severely disabled as a result of causes ranging from traumatic brain and spinal cord injuries.Generally it is extremely difficult to carry out everyday tasks without continuous help. These individuals are completely dependent on wheeled mobility for transportation inside and out of their homes. Many of them use electrically powered wheelchairs (PWC) that are the most helpful tools wallowing individuals to complete daily tasks with greater independence, and to access school, work, and community environments. Unfortunately, the default method for controlling PWCs is by operating a joystick control which requires a certain level of physical movement ability, which may not exist in people with severe disabilities.In this project we are going to design and develop wheel chair driving system with the help of voice, keypad and with touch screen.

    ABSTRACT: Inductive power links are a popular method of wirelessly transferring power to small devices. High efficiency power transmitters such as the Class-E transmitter are the preferred choice for frequencies up to the low MHz range, however at frequencies above 100 MHz, the circuit does not produce a high enough efficiency. This paper investigates the consideration of parasitic elements of the transmission coils in the circuits, showing an improvement in the circuit's performance.
