In the 1800s, studies had been started on how to track eye movements. The simple pattern of eye movement can be observed during reading of some book . From this it is inferred that the eye movement is not traight forward over still text. The main difficulty for successfully tracking the eye movement is the availability of low cost eye localization tool. So we have successfully develop the eye tracking algorithm used to localize and find the position of eye center with 90 % accuracy.
In this project, we have provided the solution to the problem, “How someone can interact with other persons, when your brain is functional but your body is paralyzed.” Therefore, we made a low-cost eye-follower glasses and software too l that
al low people suffering from any k ind of degenerative neuromuscular
syndrome to write and draw by tracking their eye movement and translating it to lines
on a screen.

FOC rotates the stationary stator reference frame to rotating reference frame attached to rotor flux linkage space phasor which results in decomposition of stator currents into torque and flux producing components under orthogonality. This will then give fast dynamic response as compares to scalar drives i.e. Variable Frequency Drive. So vector control is a mean by which we make sudden stepwise transition from one steady state operating condition to another and controlling high peak voltages and current transients during this transition. This makes control accurate in every working operation (steady state and transient).

These power systems will require interfacing of various energy sources. To enable multi-source technology, a multi-input power converter is of practical use. An ideal multi -input power supply could accommodate a variety of sources and combine their advantages. Traditionally transformer based or inductor based Multi port networks have been used, but they occupy more space and losses are also high. So to overcome this, in this paper, a switched capacitor voltage copier (SCVC) is introduced, which has less number of components.

We then changed our plan to build a tachometer from a mouse. Later we found a arduino java library that allowed access to the output of the mouse. When we tried to use the library an error came up because the library for the older arduino software didn't work. We then had changed Wprogram.h to Arduino.h. We then tested the mouse with arduino and it had worked. Next, we had measured each mouse part to find out how many rpms the mouse ball and the gears could turn. We had set up the motor test unit 147 and 549 and had hand counted the rpms off of the slow gear. When we finished the slow gear, we had then hand counted the next gear.We then set up the fast gear into the tube that connects to the motor. It had calculated to be 33 rpms on the serial monitor. We then made a prediction for the slow gear, tested it and had confirmed that mu. equals 33 rpms.

To access the control unit, the user should send an authentication code along with the required/desired function/action to his/her home control system via DTMF. This makes the use of DTMF(Dual Tone Multi Frequency) technique. The DTMF Decoder circuit is made using M8870 Decoder IC.
