Non Volatile Memory Technology Symposium

In our project non volatile memory technology symposium (OUM); we presented solution for the limitations facing by the modern day digital memory devices. Ovonics Unified Memory (OUM) is the most advanced technology which had unique abilities in proving High endurance, low power, nonvolatile RAM with high speed facilities.

Non Volatile Memory Technology Symposium

OUM is a non-volatile memory which stores memory by using chalcogenide materials. This material comes under VI elements of the modern periodic elements. It is an alloy consists of germanium, antimony, and tellurium used for the storage of data in memory devices.

Next generation memory devices:

Apart from many more memory technologies the semi conductor technologies are gaining enormous attention in providing reduced cost/bit storage devices. The mechanism in these OUM devices is a reversible structural phase-change mechanism from the amorphous phase to a crystalline phase in a thin-film chalcogenide alloy material. OUM technology implements the conventional CMOS process to form the thin-film memory element.

Data writing mechanism:

Primarily the alloy is heated up to its melting point and rapidly cooled for getting amorphous substance and to get crystalline substrate it get heated below the melting point and make to settle down the crystalline particles for 50ns, And then programmed the programming is done in OUM devices by electrically Altering the structure i.e. amorphous or crystalline, of a small volume of chalcogenide alloy. The memory state of the cell is determined by reading the resistance.

TV Remote Controlled PC and Devices with Password protection

The main aim of this project is to control the computer system using TV remote in a secure way (password enabled). This system also controls the electrical devices connected to the same system. Instead of using mouse, one can use the TV remote from certain distance. This remote can perform all the functions that mouse carries like, Left-click, Right-click and movement of the cursor etc. This facilitates user to open or close any documents, control music system, Google application control etc. User can also use Internet service using on-screen keyboard application which is default with windows.

This system makes use of electromechanical switch called Relay to which the appliance to be controlled is connected. This switch is interfaced to the Microcontroller. The Microcontroller controls this switch according to the input it gets from the IR receiver.

This system consists of an IR receiver that receives the Infrared signals from the TV remote. These signals are fed as input to Microcontroller which processes them and the commands specific to PC operation are sent to the application running inside the computer. The communication between the microcontroller and PC is done by the use of Serial RS232 communication. By using this we can operate any software in computer system like windows media player, browser and etc… To achieve this task, the Microcontroller is programmed with intelligent software written using Embedded C language.

Automatic Room Lamp Abstract

Automatic Room Lamp


First, let us understand why to use Automatic room Lamp? Now-a-days we are going through lots of advertisments of saving electric energy. With the help of Automatic room Lamp we can save and reuse energy. Find the simple block diagram of Automatic room Lamp.


The above block diagram of Automatic room Lamp used to disables the room lamp at day time and enables at night night time. Light Dependant resister(LDR) is the key element of Automatic room Lamp.


We need to fix LDR Circuit near to the window/door of home where it can receive maximum sunlight.At day time if we open the door, the resistance of LDR Circuit reduces and leads the transister to remain in cut-off state. So the relay doesnot energize enough,and lamp remains off.
At night time, the resistance of LDR Circuit becomes high and its makes the transistor from cut off state to conducting state. The relay becomes energize and makes lamp to switch on.

We need power supply too operate the following operation.



This is block diagram of basic power supply circuit. Transformer is used to step up or step down the input voltage. The bridge circuit is used to convert the alernating current to a pulsating direct current. Since pulsating dc is not desirable, we used filter to convert it to more desirable dc. Regulator is used to maaintain the output of the power supply at a constant level.

Benefits :

Operated only at +5V(d.c)

No use of man power

Used in:

  • Houses
  • Educational Institutions
  • Medical halls
  • Shopping Malls

Recycling Technology Innovation Paper Presentation Seminar Topic

Introduction to Recycling Technology Innovation:

When we feel a certain thing of no use we throw it has a waste. The natural wastes can be dumped in the soil and they get decomposed after some years and they do not pollute the soil or the environment. Here We have implemented Recycling Technology Innovation for reducing electronic wastage’s in present business world.

Now a day the usage of electronic devices has increased a lot and do not have a long life so they are thrown off as a waste and they do not get decomposes in the soil and due to the silicon and other chemicals present in these devices they pollute the environment to a larger extent. The only way to reduce this is to recycle them. In this paper we will the recycle methods on electronic wastes.

Recycling Technology Innovation

Measurements to reduce and Recycling e wastes:

The companies should manufacture the devices with a recyclable material and the usage of silicon should be reduced and an alternative should be found for that. Recycling industries should be encouraged so that the waste material can be reduced and the pollution can be under control.

The usage of ferromagnetic materials and phosphorous and chemical material should be completely controlled because they form poisonous gases when they are burnt and spoils the soil when buried in soil.

Recyclable plastic should be used in the electronic devices so that the wastage can decrease a lot and the companies a reuse the same material which greatly cut downs their manufacturing costs.

Future Recycling Technology App Development:

The electronic wastage should be reduced otherwise it becomes a serious threat for the nature and they cannot be decomposed. The government should take necessary actions and the people should be made aware regarding the effects caused by electronic wastes.

GSM Based Home Security System Project ECE Idea

Project Title:

GSM Based Home Security System Project

Introduction to GSM Based Home Security System Project:

When we talk about the security the one thing come in mind that whether our home is secure or not. It is must to secure our home first then look at other things. Our home has always important documents, money and other precious things, that need to be protected from the intruders or thieves.  We also need to protect the home from fire and gas leak as they can also destroy our home.  We can use security device at our home that will warn us from any harm by alarm or sending SMS to cell. We can use 8051 micro controller or 89s52.

They are low power chips. They are high performance chips with 8 bit and they is flash memory for storing data.This flash memory allows them reprogram when required. Flash are made up of monolithic chips as they are highly flexible and loss cost. They consist of 32 I/O lines, timers, pointers, oscillators, and clocks etc.

For this microprocessor we use the software called Kiel u- version. This provides tools for the development of the software of the 8051. With the help of this we can generate embedded applications. They use the protocol command named as AT command. They receive the message comes from the phone, then decode the SMS, authenticate the number. Then use their ports to control the specific appliances and after the operation send the feedback to the users for the confirmation.AT command sets are used for the GSM service to connect the device with the mobile phones.
