Technical CSE Seminar Topic on Bio Metric Systems

Collecting a data to identifying a person in manual way is time taking process, involves more risk for implementation and maintaining the data. In the present world data was easily misused by frauds. To secure a data from those people’s data should be maintained very confidential and access of data should be highly secure. For maintain the data in such manner we need highly protected system to maintained above things. For that Biometric system is very useful.

The Biometrics system is a device, by using this maintaining and implementation of the data in high secured manner. Using this data was not misused by any other persons.

Biometrics is an automatic mechanism used for the capture the real time persons finger prints and pictures. Biometric is containing the three type of identification, the mechanism is automated, storage process and interact with different applications.

Biometric system is contains two stages

Stage one: Enrolment stage

Stage two: identification stage

Enrolment stage contains scanning the data and the obtained data was stored

Identification stage contains cross checking the data with stored data, if it is matched system gives the permission for the proceedings

A sensor is scan for the physical density and creating digital presentation, there are two type of the topology to identifying the Biometrics physical and behaviour. The physical is depends on the identifying faces, finger prints, Hand and eye. Behaviour is taking the signature of the person and voice.

The limitation of the using the Biometrics only the user allow to perform an identity otherwise it should paly alarm alters.

Cost also increasing to scan for different human identifications. Voice is the least cost one.

Hand and IRIS are the highest cost one and give the good performance.

The Iris is a technology is used for to identify for the retina and eye colour.

The IRIS data is identifying the using the Rainbow. The Eye black one most powerful identities, this is the Technology used to identifying the person in ATM Canter and cash machines. While using the ATM canter pictures should be captures very easily when any illegal thing should be happened. The IRIS data should be unique.

Vehicle Monitoring and Control System Using Micro controller Project

Introduction to Vehicle Monitoring and Control System Using Micro controller Project:

We know that most of the accidents involve heavy vehicles such as trucks and busses. The main reason is because of them using huge engines and complex running structure compared to smaller cars there is greater risk of any of the system being failed while the vehicle is moving at a high speed or even because of driver error an accident may be caused.

Hence there is a need to monitor the vehicles parameters such as speed of the vehicle, temperature of engine, fuel availability, battery monitoring, proximity detection and coolant level is essential for the safety of vehicle. This information should not only be visible to driver but also to the base stations/owners.

In this system we make use of PSOC – programmable system on chip instead of microcontroller which reads all the parameters of the vehicle and transmits the same data to base stations using RF frequency.

PSOC’s has powerful processor architecture, advanced peripherals, Flexible on-chip memory, precision programmable clocking, programmable pin configuration, additional system resources and complete development tools.

Operation: – The important parameters of the vehicle are measured using appropriate sensors and this information is transferred to PSOC. Then the PSOC samples the data at regular intervals and the corresponding actions to be taken are stored in its memory for later or immediate action.

The speed of the engine is monitored every second and is converted into RPM which is displayed to driver continuously and when speed exceeds a certain value, the PSOC automatically activates a motor which apply the brakes. In this way the speed is limited to a predefined value.

Similarly all other parameters can be sensed and controlled immediately or at later stage at a base station. Hence this system of Vehicle-monitoring and control system using microcontroller helps in better management of heavy vehicles and reduces the accidents to highways to greater extent.

Vehicle Density Based Traffic Light Signaling System

Introduction to Vehicle Density Based Traffic Light Signaling System Project:

Traffic management is one subject on which every year millions of dollars are spent across the world to provide better traffic management. Especially in the developed countries such as India there is huge scope for a better traffic management.

Presently traffic is managed manually at smaller junctions and by using the signals lights (Red – Green – Yellow) at major junctions. This system will not serve for effective using of road space in major cities. The latest technology that can be employed is by using signal lights which function based on density of vehicles on the roads.

In this system all the timings of signal lights are fed to a computer basically termed as base station and through this station all the signals are sent to microcontrollers (89C51) placed on signal lights to operate accordingly. Sensors are connected to microcontrollers on every signal location which senses/reads the density of traffic in that particular road and sends the information to base station. Hence a bi-directional information flow system should be in place between signal lights and base station. Based on this information on density of traffic the signal light timings are automatically changed and also if needed traffic will be diverted to roads where traffic is less.

For sensing the traffic we can either use laser sensors or inductive type metal sensors. For transiting data we can use 433 Mhz carrier frequency. And use RS232 protocol for microcontroller (895C1) communication.

By deploying this model in real time we can save time being wasted in standing at signal, petro / fuel consumption can be reduced and make traffic management accurate.

SMS Based Vehicle Location Finder for Parking ECE Seminar Topic

Introduction to SMS Based Vehicle Location Finder for Parking ECE Seminar Topic:

In present day life cars have become a common commodity to every family living in cities. With cars some problems such as security and parking is a common thing. Car parking has some glitches to it such as parking at right place and finding it back when we want to move out. In huge parking lots and multi storied parking lots there will be some confusion in finding the car because where we had parked the car and how to get it out. To solve this problem here is a simple system designed to give the direction where the car is. This system is based on microcontroller and GSM technology which is called as “SMS based vehicle location finder”.

We use a mobile phone to trigger a microcontroller which in turn controls an appliance such as a buzzer to ring an alarm and also the microcontroller acknowledges by sending an SMS that the buzzer is ringing or the lights of tail lam are flashing.

The main components in this system are AT command supporting GSM mobile phone, 89S52 Microcontroller, Max 232 IC, Relays, Relay driver IC ULN 2803, Voltage regulator 7805, Diode IN4007 and GSM Phone. The software used is Keil-U-Vision 3.0 in this software by using Keil tool set we can generate embedded applications virtually with supported microcontrollers. AT command is the communication protocol used between GSM phone and microcontroller.

The theory/principle used in this project can be used in different fields apart from just car parking application. We can use it to trigger a security alarm for vaults, to turn ON motors remotely using GSM handsets and many more.

Technical Seminar Report on Wireless USB

Introduction to Technical Seminar Topic on Wireless USB:

Imagine if we can transfer data from computer to printer, camcorder, Cell phones and other customer electronic products without any wired USB connection. This can be possible if Wireless Universal Serial Bus (WUSB) becomes a reality.

USB is the one of the most successful customer electronic product in the last 10 years. It is the de facto interconnect to most of PC’s around the world. Wireless USB specifications are designed for transfer of high speed data. In 2004 WUSB promoter group is formed which includes Agere Systems, HP, Intel, Microsoft Corporation, NEC, Philips Semiconductors, and Samsung Electronics.

Wireless USB has wide usage in both home and industry applications such as Entertainment PC, Digital Camcorder, Digital Still Camera, HDTV, DVD-RW/CD-R, (Recorder/Player), External Storage, Device (HDD), Game Console, MP3 Player, Set Top box, mobile device, Personal Video, Player (PVP), Personal Video, Recorder (PVR), Printer.

Topology / Technology requirements: – WUSB device works on ‘husband-spoke’ topology. The host is responsible for transferring data among devices connected to it by allotting bandwidth and time slot to each device. We can call them as clusters. There will be point to point connection between wireless USB host and Wireless USB device. In this connection type hubs are eliminated. A host can be connected to 127 WUSB devices at a point of time. Even if there are multiple wireless USB devices connected to same host the clusters co-exist within the same environment / radio cell. In the next stage connection between two hosts and a normal USB is also possible. Wireless USB will be based on the Ultra-Wideband (UWB) radio.

Since security is the major aspect Wireless USB has to deliver the high standards of security just as wired USB. Authentication of devices before operation of device is needed for connection-level security between devices. At application level encryption needs to be implemented. The installation and operation of wireless USB should be made simple and opera table.

ECE Seminar Report on Simple Speed Control Method For Small Induction Motors Base On Phase Difference

Introduction to Simple Speed Control Method For Small Induction Motors Base On Phase Difference Seminar Topic:

This paper proposes method for speed control of induction motor with out of the sensor. There are various methods available for controlling the speed of induction motor but they require additional equipment and expensive. By using a equivalent circuit we will calculate the phase difference and based on that load torque is estimated for controlling the speed of induction motor.

Working model:

For calculating the phase difference an equivalent circuit is designed. The power factor is the most important factor for estimating the rotor speed. From the measured values we can assume the relation between phase difference between and the torque. Here the phase difference is converted into time difference for estimating the torque characteristics on a digital counter. Here a L type equivalent circuit is built for calculating the phase difference.

By calculating the phase difference for stator currents we will control the speed of motor. As the load torque changes the rotational speed of motor also changes so a microprocessor is used for calculating the load torque values so as to maintain a constant speed. Here a control circuit performs the respective operations for maintaining the constant speed of induction motor. The tests are performed to check the accuracy of the circuit, different load torque conditions are applied and values are compared to see the changes for different operating frequencies.

Applications:

The induction motors are extensively used in various house hold devices like refrigerators and air conditioners and also in industrial devices. This is cost effective device for controlling the speed of induction motors.

Efficient and Economical Solution for Traffic Congestion in Urban Areas ECE Seminar Topic

Introduction to Efficient and Economical Solution for Traffic Congestion in Urban Areas ECE Seminar Topic:

The main aim of this project is to reduce the traffic problems in urban areas. The entire project is done using single beam analysis and manual or ms excel method and finite element method. The traffic in the various areas is analyzed and various methods are proposed for controlling the flow of traffic. In this paper we will discuss how various methods are used for controlling the flow of traffic.

Brief into the methods for controlling traffic problems:

The traffic at various junctions is calculated and the flow of vehicles is noted for different timings. By taking preventive measures and by making new road constructions the traffic problems are overcome. By halting the flow of cars in narrow streets and by using some alternative routes the flow of traffic is controlled. By using public transport system in busy areas the use of their own vehicles gets reduced by the people. By constructing fly over in the busy areas the traffic gets controlled. In busy timing by making the vehicles to go in one way the traffic problem gets reduced. By constructing multistoried parking buildings the space for parking on busy roads gets reduced. 

Finite Element method:

In this method system of points create a mesh which gives the characteristics of the structural design. This method is used for construction and maintenance of under pass flyovers. When the vehicles are flowing on the flyovers by using this method we can develop a spread sheet for measuring the stresses and visualizations on the bridge and to check the structural defects. Thus we can conclude that these methods can be implemented in metropolitan cities for controlling the traffic problems.

ECE Seminar Topic on Breathe Alcohol Tester with Seminar Report

Introduction to  Breathe Alcohol Tester with Seminar Topic:

Breath alcohol tester is an electronic device which the information of alcohol level in blood by analyzing the breath exhaled into the system. This device employs a semiconductor device for measuring the alcohol level in blood. The advantage of using semiconductor device is that it is highly robust and highly immune to shock and vibration and more reliable. There are other methods for finding the alcohol  level in  blood like chemical reaction and infrared absorption method which are not that effective like a semiconductor device and they are very expensive and have a short life time. In this paper we will discuss the working and applications of alcohol testers.

Working model:

The alcohol levels are tested by using a sensor which consists of semiconductor material and is protected by a double layer of stainless steel screening and the device is mounted on a ceramic tube. When the alcohol tester is on the sensor which consists of a semiconductor gets heated to normal temperature which causes a depletion layer to form between the surface and sensor and it absorbs oxygen at this time and  shows high resistive properties and if a drunken person is blows his breath , the alcohol reacts with the oxygen and the changes occur in the depletion layer and it shows low resistive properties and the circuit calculate the level of alcohol according to the change in the resistive properties.  A 7805 voltage regulator which supplies a 5v dc is used for heating the coil present in the sensor.

Applications:

These are use by traffic police to restrict the drunken drivers from driving the vehicles during night time. This is fast method for giving the alcohol level in the blood whereas the normal chemical reactive methods take a lot of time for giving results. This method can also be employed for knowing the toxic levels in blood.
