The magnetic tape reader on an ATM is useful to recognize the customer’s profile by reading the magnetic codes on his/her debit card. After correctly giving the customer’s secreting PIN code, the account can be accessible now. In computer security, shoulder surfing refers to using direct observation techniques, such as looking over someone's shoulder, to get information. It is commonly used to steal PIN. This project introduces a novel technique for ATM debit card PIN security by incorporating an embedded system based Virtual Keyboard technique. The main idea behind this concept is create the virtual keyboard per single PIN digit. This keyboard is randomly generated by Microcontroller and it is producing different set of key arrangements during each PIN digit in order to avoid the shoulder surfing issue. The great adv

project center in Tirunelveli  The project is designed to control a robotic vehicle using an android application. Bluetooth device is interfaced to the control unit on the robot for sensing the signals transmitted by the android application. This data is conveyed to the control unit which moves the robot as desired. An 8051 series microcontroller is used in this project as control device. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. Transmitting end uses an android application device remote through which commands are transmitted. At the receiver end, these commands are used for controlling the robot in all directions such as forward, backward and left or right etc. At the receiving end the movement is achieved by two motors that are interfaced to the microcontroller. Serial communication data sent from the android application is received by a Bluetooth receiver interfaced to

Great people like Stephen Hawking and Max Brito have been suffering from this crippling phenomenon. Our project is an attempt to make lives of the people suffering from this phenomenon simple and by simpler we mean self-reliant, which will thereby reinstate their confidence and their happiness. The idea is to create an Eye Monitored System which allows movement of the patient’s wheelchair depending on the eye movements. We know that a person suffering from quadriplegia can partially move his eyes and tilt his head, thus presenting an opportunity for detecting those movements. We have created a device where a patient sitting on the Wheel Chair assembly looking directly at the IR sensor, is able to move in a direction just by looking in that direction. The IR signals are monitored by an embedded system, which will then guide the motors to move

project center in Tirunelveli  Power transmission line has been usually inspected manually by workers riding in gondolas that travel suspended from the transmission lines or watching with telescope in the ground. In recent years, it has become increasingly necessary to perform inspection work with the autonomous inspection robot in power transmission line. This project describes the development of a mobile robot capable of clearing such obstacles as counterweights, anchor clamps, and torsion tower. The mobile robot walks on overhead wires in transmission tower. Its ultimate purpose is to automate to inspect the defect of power transmission line. The inspection tasks are performed by the robot carrying detection instruments and rolling/crawling along the overhead ground wires. The installed camera in the robot will inspect the transmission cable wear and tear defects and the insulator defects also inspected by this efficient system. The IR sensors present in the robot system is u

Therefore, it is important to rapidly detect and report faulty streetlights (FSLs) to the relevant authorities to keep roads safe. Currently, communities primarily depend on electrical inspectors to check streetlights regularly, which may result in long and unnecessary delays prior to repair. Recent studies have focused on adding a networking capability (i.e., a wireless sensor network) into street light poles to enable real-time status reports. However, a smart system that would incorporate sensors and network modules into every streetlight would be expensive; therefore, it would be nearly impossible to realize this system quickly. In this project, we propose a noninvasive method for detecting faults on the solar based street lights that involves with the collection of information about streetlights’ intensity. The collected data would be used to intimate the authorized person in the c

project center in Tirunelveli  GSM based LPG weight and LPG leakage detection system has application in Home, Hotels, Restaurants, as well as in industries. This Project is used to monitor the weight of LPG gas cylinder. In our home we observe whenever LPG gas cylinder is empty. We give request for new cylinder at the office of gas cylinder provider. Many times it happens that because of the Rush or due to the shortage of cylinder, there is a delay in providing the gas cylinder. Main reason behind this is delay in informing to the gas provider or we inform the gas provider at the last moment when the gas is empty. One more example in hotels or sometimes in industry also the LPG gas is also used. In home or in hotels the main purpose of LPG gas is for cooking. But in the industry sometimes, LPG gas or some other combustible gas is used for some other purposes like welding or cutting or for some other use. In these places if the LPG gas inside gas cylinder was finished at that tim

project center in trichy  A family of voltage-double magnetically coupled impedance source networks (VBMCISNs) is presented. The scheme of the proposed family is that adding the auxiliary capacitors and diodes to the magnetically coupled transformers to realize the voltage-double function. The proposed impedance networks can produce the higher voltage gain, reduce the voltage stresses across the passive components, have a common ground, realize the continuous input current and suppress the start-up inrush current. Finally, one of the resulting topologies is verified in the condition of DC-DC converter and DC-AC converter, theoretical analysis and experimental results are offered to verify the topology’s validity.

project center in trichy Electric vehicles (EVs) are becoming increasingly popular as a means of future transport for sustainable living. However, wireless charging of EVs poses a number of challenges related to interoperability, safety, pad misalignment etc. In particular, pad-misalignments invariably cause changes in system parameters which in turn lead to increase in losses as well as reduction in power throughput, making the charging process long and inefficient. Consequently, wireless charging systems that are less sensitive to pad-misalignments have become preferable. This paper, therefore, presents a hybrid Wireless Power Transfer (WPT) system that charges EVs at constant rate despite large misalignments between charging pads. The proposed charging system uses a combination of two different resonant networks to realize a constant and efficient charging process. A mathematical model is also developed, showing as to how the two resonant networks can be combined to compensa

project center in trichy Modular power converters are expected to play a major role in medium and high voltage/power applications. Normally, each module processes the same amount of power, however this does not take into consideration that different modules can have a different remaining useful lifetime. This paper proposes the concept of power routing for cascaded H-bridge (CHB) converters, with the purpose of delaying the failure of the system. A third-harmonic injection into the duty cycles allows extending the imbalance capability of the structure, keeping the CHB operational even if some power paths are completely unloaded. Analytic investigation in conjunction with simulation and experimental measurements demonstrate the power routing by means of the proposed method.

project center in trichy This paper presents a novel loss minimization technique for Induction Motor Driven Elevator Systems (IMDES) to determine an energy optimum velocity pattern. The objective function consists of a differential equation relating total power losses in the induction motor to its rotor speed. The constraints are provided in terms of velocity and acceleration governed by passenger comfort. Since, the velocity and acceleration are state variables, Pontryagin’s Minimum Principle is used to determine the most optimum trajectory by forming an appropriate Hamiltonian function. Boundary conditions are specified and used to obtain the coefficients of the rotor speed equation. As the velocity is optimized, the total travel time is not fixed and treated as a variable. A fixed-point iterative procedure is used to estimate the travel time. Additional loss minimization is incorporated by optimizing the machine flux for the constrained portion of the velocity pattern. An al

project center in trichy Generally, single-stage buck-boost inverters consist of distinct circuits operating individually in buck/boost or positive/ negative modes, the latter definitely leading to crossover distortion in the output current. This paper proposes a switching strategy that changes the bi-modal operation of a single stage buck-boost topology to a single mode inverter (SMI). This is due to the consequent voltage gain which ensures that the output voltage polarity, apart from its magnitude, is an exclusive function of the duty ratio. Operational principle and salient hardware design are explained with the help of equivalent circuits. Details about the dynamic model are presented, based on which controller design is carried out for both stand-alone and grid-connected operation. Experimental results obtained from a 300 W, 110 V laboratory prototype are presented to validate the performance of the proposed switching strategy.

project center in trichy This paper proposes a switched-capacitor multilevel inverter for high frequency AC power distribution systems. The proposed topology produces a staircase waveform with higher number of output levels employing fewer components compared to several existing switched capacitor multilevel inverters in the literature. This topology is beneficial where asymmetric DC voltage sources are available e.g. incase of renewable energy farms based AC microgrids and modern electric vehicles. Utilizing the available DC sources as inputs for a single inverter solves the major problem of connecting several inverters in parallel. Additionally, the need to stack voltage sources, like batteries or super-capacitors, in series which demand charge equalization algorithms, are eliminated as the voltage sources employed share a common ground. The inverter inherently solves the problem of capacitor voltage balancing as each capacitor is charged to the value equal to one of input vo
