Introduction to ECE Final Year Eye writer project:

The main objective of this project is, generally most of the people can read, write, listen, and do anything because of their body communicate with mind. So mind controls every moment of the body. But some of the people can’t do like this because of their body may not communicate with their brain, means brain is active and body is in-active. This kind of people can think but not implement their thoughts. Many scientists were researched and designed “A EYE TRECKER”   for this kind of people. By using eye tracker they can implement their thoughts; this kind of application is called as” AN EYE WRITER”.

                               This eye tracker is used for finding the eye moments and positions from left-to-right, right-to-left and up-to-down, down-to-up and also location of the object. This is used for who are suffering from neuromuscular syndrome. According to the eye moments of the people to write and draw their thoughts and translate these moments into lines on the screen. Eye trackers are three kinds. First one is magnetic field sensor or special contact lenses (which are made by embedded mirror) are attachment to the eye and this sensor or mirror is around with eyeball. It does not slip when the eye rotates. First tracker is used for measuring exact moment and sensitive dynamics of eye.

                               Second one tracker is non-contact optical system, in which infrared light is reflected from the eye which is sensed by the video camera. It is used for measuring the eye motion. And the third one tracker is electrodes, which are placed around the eye uses electro potential is used for measuring the slow eye moment and detecting the gaze direction. Both positive and negative electrodes placed around an eye are called “ELECTROOCULAGRAM” (EOG). Generally there are two eye track techniques, which are Bright pupil and Dark pupil. Difference between these techniques is ON-Axis lighting and OFF-Axis lighting between camera and reflection of light path from eye.

                               Advantages are low cost and are most applicable for cognitive studies, medical research, human factors, computer usability, adult research, in-vehicle, etc. commercial applications are web usability, television programs, advertising media, package designers, both younger’s and  order’s.

Introduction to A Smart Reorganization Of Vehicle Based E-Governance System In Mobile Device Project:

Now a day the traffic plays a very important role in our day-to-day life activities. It is the most problem for job holders, business mans, students, etc (the people), Not only in city but also at highway passageways. Now some business persons have provided the toll gate systems at highways. Basically the purpose of tollgates is to recollect the amount from the vehicles, which have been coming from out of city or town. It was provided by the person, who has taken the road contract of that area. Only they will collect the toll payment. In this process if many vehicles are come, they should follow queue and traffic is heavy in that place. So it will take time to reach their destinations. To overcome these types of problems, a new Electronic Toll Collection (ETC) was introduced. It is the technology for electronic payment of toll. It checks whether the vehicle has registered or not and give the alerts. If any violence occurs, debit the related account. So there is no chance to stop the vehicle at the tollgate. This kind of technology was implemented in united -states and other countries. So we enriched the toll collection technology. Now the fast technology in ETC with RFID (Radio Frequency Identification) is started.

                              RFID is released up to 950MHZ, the main advantage of intelligent transportation systems (ITS) is by using computer technology, electronic technology, and modern communication technology develop the ECT with RFID and vehicle safety. By using this we can avoid the traffic jam problems, can create safety road environment. Etc. The main aim of this project is to design a automatic tollgate system as well as online transaction with vehicle security through mobile by SMS.

                              The software requirements are Windows XP OS, Java framework, MySQL DB and hardware requirements are RFID, GSM, GPS, PC, RS232, Camera, and Microcontroller.

                               Global system for mobiles has been working in global position system. Camera is located at the vehicle position, so it will take the photos of a vehicle and RFID generate the magnetic radiations and frequency on the number plate of the vehicle. If the vehicle has registered already then no problem if not alert SMS has been sending to the owner of the mobile.

For data transfer RS232 cable is used and controller is used is for the controlling of those sections purpose. SNMP is one of the protocols, which is suitable for network management of ETC system because it’s easy use and strong expandability. By using this we can develop the highway efficiency, speedup the vehicle passage and decrease the possibility of unsuccessful and mistaken collection.

Introduction to A New Single Phase Soft-Switching Power Factor Correction Converter:

           From several years, the power electronic systems and devices have been playing important role in our day-to-day life activities. By using these electronic devices frequently, they should generate harmonic current because of their destroying or damaging the electricity network.  Receiver should be affected by the harmonics while doing the operation on receiver. To overcome this effect our engineers are creating electronic devices.

             The main role of this project is, by using low harmonic and High-power factor converters with soft-switching (SS) techniques improve the efficiency, high reliability and decrease the cost of components. These converters are used because of the previous used converters (A-D converters) have some disadvantages are low power factor and voltage distortion, slow varying ripples at output dc load, low efficiency and large size of ac and dc filters because of low power  quality in terms of injected harmonics. High-switching frequencies are being required by these converters. High switching losses, increased electromagnetic efficiency (EMI) and reduced converter efficiency all these drawbacks are caused by the operation of high-switching frequency. To overcome these drawbacks we should use those SS techniques.

                        In the working principle, mainly SS has four types of groups are zero-voltage switching (ZVS), zero-current switching (ZCS), zero-voltage transition (ZVT), and zero-current transition (ZCT) with pulse width modulation(PWM) control. In this operation we have switching power loss; it has current and voltage losses during switching period. Power diode’s reverse recovery loss and discharge energy loss of the main switch parasitic capacitance. Compare to previous converters ZVS and ZCS are advanced, compare to these converters ZVT and ZCT are more advanced. So switching power loss is completely overcome.

                        In this we have mainly two switches. One is  Main switch with main diode consists of one parasitic capacitance of main switch and diode, upper and lower snubber inductances, One snubber capacitance. Another switch is Auxiliary switch consists of four auxiliary diodes; One is magnetization inductance, output and input leakage inductances of the transformer respectively. For one cycle twelve stages will be taken by the proposed converter. To achieve this SS there must be four conditions; Main switch is turning ON with ZVT and turn OFF with ZCT. Auxiliary switch is turn ON&OFF with ZCS.

        The features of proposed converter are there is no extra current or voltage stress on the main switch and main diode, all semiconductors and other components work with SS, passive snubber is not required, a common ground is used for both main and auxiliary switches so easily control the converter, by using silicon carbide (SIC) diode’s reverse recovery problem will be recovered, etc.

     Finally by using this new proposed converter (PFC) realized with 200v ac, getting output is 400v dc , It is switched with 100kHz for 300W output load. For full load 98% of efficiency will achieved. Finally 0.99 value of power factor was reached by our new PFC converter with sharp sinusoidal signal.
