Radio Identification Method Third Year ECE Project Report

Introduction to Radio Identification Method Third Year Project:

This method called the radio identification method is the automatic recognization method which works on saving and replying the data that is retrieved from the Databases by the device named as the RFID. This RFID is such a tag item which is joined or connected to the animal or a product or any person for the reason of identifying it by making the use of the radio waves in it. This RFID is a small tag which has presence of silicon chips and antennae in it. There are two types in the RFID tags namely the Passive Tag and the Active Tag. 

The Passive tag is the tag which has no interconnected power supply. The electric currents are then connected in the antennae’s which are present in the tags. This passive tags works by giving signals by setting it back the carrier path from the user reader. Here the present antennae are compulsory need to be circuited by the incoming signals waves and also by the transmitters too.

Active tags have it own interconnection supply of current in it. This interconnection current is then made in use of getting the outgoing wave signals. The defense system of the united has properly used this system to low down the price and change the production of arm weapons too. 

The latest on working applications of the radio identification method are firstly the passports here this device is to give the passports to the people applying for it. Second is the Transport payments system here payments of the online travelling tickets are made by the means of Credit Cards. Third is the product tracking in which this device is used to track the barcode number of the products which are kept on sale. Automotive and animal identifiers are couple of other applications.

ECE Seminar Topic on Interfacing human brain with computer

Introduction to Seminar Topic on Interfacing human brain with computer:

Interfacing human brain with computer is the concept comes under a brain–computer interface (BCI), also called as mind-machine interface (MMI), it is a direct means communication between human and machine. Its either receives commands from the brain or delivers signals to the brain from the machine, In order know the thoughts and thinking power of a human brain this concept comes to existing providing the easiest way of way performing tasks in a very less time just by giving commands through our brain. In this paper we discuss about various kinds of brain computer interfacing like Electro-encephalography (EEG),

Magneto-encephalography (MEG),

Functional magnetic resonance imaging (FMRI),

Positron emission tomography (PET),

Optical technique,

Adaptive Brain Interface (ABI).including their advantages and disadvantages with a proper feedback system.

Existing system: Interfacing human brain is basically start with first most concept Electro-encephalography (EEG), where multiple strands are placed inside the skull in order to take the brain signals. However, this method not achieved the desired results due weak readings. Presently research is being conducted in these fields Using integrated chips inserted into  the brain that have multiple pins having a width equal to human hair  and those are inserted into the cerebral cortex, scientists creating a scope of reading the instructions given by the brain through the pulses produced.

The response of the neural pulses is then sent to a computer which translates by using specific coding and decoding algorithms into required digital computer language. And then it is processed to another computer that receives the information and controls the machine by giving commands.

 Future scope: we can provide multiple connections into the brain with the scope understanding the human levels and to transfer a wide range of information into various parts of the human brain either through direct control or indirect control over the conditions of all individual units in the brain by means of artificial robots.

ECE Seminar Report on Voltage Regulators

Introduction to Seminar Topic on Voltage Regulators:

In this paper we dealt with the importance of voltage regulators in every day transmission and distribution of electricity. The main aim of the voltage regulators is to provide a constant voltage over a wide range of varying load conditions this phenomenon comes under the concept of voltage regulation. Electrical system under fault conditions may not work up to the expected way or stops working permanently. The proper working of the total network depends upon the various factors like voltage sags and surges, voltage sags are one of the main causes for voltage fluctuations. Voltage sags are the most common type of faults occurred in the power transmission .

Voltage Sags and voltage dips are caused due to the abnormal increase or decrease in loads like short circuits faults. In order to overcome these undesirable fault conditions and to maintain the voltage fluctuations with in a range of 5% higher or lower of this margin. There is an intense need of voltage regulators and voltage stabilizers in the primary and secondary distribution networks including home appliances.

Different voltage regulators have different importance and working conditions. In this paper we come across the need of voltage regulators different major kinds of voltage regulators like electro mechanical voltage regulators ,electronic voltage regulators, ac voltage stabilizers ,series and shunt voltage regulators ,dc voltage stabilizers ,active regulators ,linear regulators, switching regulators, silicon controlled rectifiers regulators, automatic voltage regulator and  static voltage regulator  and  their working along with their importance and advantages.

Voltage regulators provide safe and secure operation of the total electrical equipment. The major advantage is its reliability in performing its operations under faulty conditions and providing the consumers the benefit of cost. These days Voltage regulators became very crucial part in any electrical system providing excellent working conditions in order to make electrical transmission easy.

ECE Presentation Report on Fully Adaptive Approach to Smart Antennas

Introduction to Presentation Report on Fully Adaptive Approach to Smart Antennas:

Smart antennas are latest revolutionary future for the wireless communications in the coming days .the main aim of smart antenna is to increase the gain of antenna in desired direction Smart antennas consists of a antenna array that changes array pattern in response to signal environment in order improve the communication system, recent days the mobile communication has developed rapidly by the invention CDMA and GSM technologies along with the new technology these antenna find applications in radar, cellular wireless networks, and mainly satellite systems.

And coming to their advantages they had wide range extension, less time dispersion, multiple access interference, and multiple path management. Smart antennas is developed right from the root, they are two types of antennas kindly switched beam antenna and adaptive array antenna.

In first kind the antenna systems detect the signal strength from several fixed beams and the switch chooses the predetermine beam randomly from several fixed beams when the mobile passes through the sector, while in the adaptive array antennas provides optimal gain by operating simultaneously, tracking and minimizing the interfering signals. In order to work towards goal for better coverage and spectral efficiency the most important areas to be concerned is frequency planning, power control, Modulation and coding, Sectorization. These can be explained in detail below.

 While considering the terms like integration, range/coverage, interference the adaptive array has its own advantages when compared with switched beam antennas is better in nullifying the interference signals, high range and coverage area, less hardware redundancy. INTELLICELL architecture is explained along with its remedies.

Future scope:

The existing space division multiple access (SDMA) can be developed to a range where more than one user can allocated to the same communication channels simultaneously in the same cell just by separation of angle only there by increasing the capacity of the entire communication system.

ECE Mini Project Report on Laser Based Communication System

Introduction to Mini Project on Laser Based Communication System:

Recent days the communication systems are changing rapidly due to this enormous development a new revolutionary concept Laser Communication System had arrived which was gaining the human attention towards it. The basic principle of operation is amplitude modulation phenomenon. In this process the amplitude of the carrier signal is varied in accordance with the amplitude of the modulated signal. The carrier signal is nothing but the signal on which we work here it is laser beam, the modulated signal i.e. the signal which is to be modulated or the signal whose parameters are going to change, is taken as the input audio signal, and mainly the term amplitude indicates the intensity of the laser beam which we use.

Laser based communication system is an invisible connections through the air and their working resembles the fiber optics links around the atmosphere. Using this new technology we can easily transmit the signals to the surroundings as quick as possible and transmit the data within a range of 500 meters without interference as here the laser torch can transmit light up to any distance based upon amplitude of the input signal.

In this paper we proposed a simple laser based communication system having two major sections transmitter and receiver, the transmitter is coupled with the laser beam of specific intensity with the help of an common collector mode transistor, the transistor used here is LM386 audio power amplifier which acts as impedance matching device acts proportional with the intensity of the modulated signal.

Now coming to the receiver end sensors are present to sense the varying amplitude of the light beam by using photo transistors and light dependent resistors adjacent with the loud speaker the transistor used here is Silicon photo transistor. The various applications are we can communicate without cost excluding equipment cost. Finally the entire circuit and its operation are checked and the results were improved.

ECE Seminar Topic on Adaptive Piezoelectric Energy Harvesting Circuit

Introduction to  Seminar Topic on Adaptive Piezoelectric Energy Harvesting Circuit :

The first thing that comes to our mind when we say electricity is the wires. Wires have led to many fatal accidents due to various factors and are considered unsafe. There is a need of a wireless electric source which provides all the functionality of a proper wired circuit. Piezo electricity can be generated from piezoelectric objects; it is basically materials such as ceramics, crystals, bones, proteins etc. These materials when subjected to mechanical force or stress, a charge get accumulated inside it. The one difference these type of generated power sources show is the capacitive nature rather than the inductive nature.

The thought of creating a harvesting circuit with this adaptive piezoelectric energy is a futuristic one. The device under fluctuating frequency and amplitude maximized power transfer almost four times than the normal charging sans a converter.

This device mainly aimed to increase the power transfer efficiency from such piezoelectric transducer to a battery which is electro chemical in nature, the whole process is done through an adaptive circuit. The other main goal is to achieve an optimum power transfer flow and also to maximize the storage of power in the battery. The whole result is analyzed and subjected to experimentation. 

The concept of an adaptive circuit has a major advantage as it is flexible than normal circuits. The rectifier’s output voltage can be tweaked accordingly in order to maximize the power transfer and in turn an increase of storage on energy inside the battery.

 A controller board is used to implement the adaptive controller, this board contains

  • Texas instruments (TMS320C31)
  • Digital Signal Processor (Floating Point)
  • Analog to Digital Converter
  • Pulse width modulator

The piezoelectric devices are subjected to constant change in amplitude and frequency in order to maximize the energy harvesting. One of the main applications of this system is embedding a RFID system and the piezoelectric device inside a shoe which contains an electronic system.

Adaptive Piezoelectric Energy Harvesting Circuit Seminar Report

Introduction to Adaptive Piezoelectric Energy Harvesting Circuit Seminar Topic:

The main problem we all face currently in the world is the over consumption of our energy resources, if we go at this rate then our future generation will have lack of supply of energy resources. Harvesting energy is a new innovative technology and this topic deals with such harvesting of electrical energy through a piezoelectric element which is excited mechanically.

The element acts similar to source which provides electrical power with only difference being that it is driven by a mechanical force and the source impedance is capacitive in nature. The mechanical force itself will be of fluctuating amplitude. An adaptive control algorithm is used in a DC-DC converter which will help it to harvest the electrical energy almost four times higher than one without it, also the rate of harvesting increases with the increase in levels of excitation. 

Any vibrating structure can become the platform of usage of this technology and main reason of having this energy circuit is the controller flexibility. The only addition to this vibrating structure would be the piezoelectric element which helps in increasing the harvesting process many fan fold. No other factors and positions such as placement of device, vibration levels etc. would affect the harvesting performance or the controller operation. 

Main components in this harvesting system: 

  • AC-DC rectifier
  • Output capacitor
  • Electrochemical battery
  • DC-DC converter (switch mode) 

Optimized designs can be developed based on the control algorithm and the proposed excitation levels or load which forms its power. The main part of this technology is the proposal of the energy harvest where we can achieve the power flow gets optimized. Standalone circuit control will be used for future designing work. The power stored in the battery is maximized with the help of implementing optimal power transfer theory. Overall this technology is definitely going to revolutionize the energy harvesting process.
