Abstract ECG Tele Monitoring Project:
This paper presents a new revolutionary concept in the field of medical sciences, with the rapid advancement of electronics in medical applications has paved path for the invention of a virtual heath monitoring system rather than conventional manually operated ECG system, here we implemented a new system “ECG telephone monitoring system comprised of an portable ECG terminal with an health monitoring system.

This system is capable of transmitting the human body signals effectively for monitoring purpose by analyzing them perfectly. In emergency condition there is an intense need of immediate and accurate diagnosis based on the condition and the body signals from the electrocardiography (ECG). This conventional method of analyzing the health conditions of the patient takes a lot of time so with an intent to reduce the reaction time we implemented this new ECG TELEMONITORING system.

This system is also known as telemetric ECG it can perform the direct transmissions in real time with in shorter duration of time facilitates a continuous monitoring over the varying parameters. And the transmission of the signal can be either through wire or wireless. Standard telephonic wires are used to transmit the data where as in wireless transmission for monitoring and transmitting the ECG signals of the patients we implement the monitoring center server based on ZIGBEE link. By this the doctor can take the prevention steps based on the ECG signals delivered by the ECG compatible software.

The design and operation of this remote ECG monitoring is clearly explained in the coming sections. Apart from several methods of recording and analyzing these ECG signals this new concept of using mobile phone in monitoring purposes, offer many advantages in real time applications. By this we can monitor the patient condition and an accurate therapy can be provided, it is a low cost and high distance coverage, can easily interface with the peripheral devices for the efficient exchange of data.

Introduction to Develop a Multiple Interface Based Fire Fighting Robotics Project:

A monitoring system that is based on the real time is presented in a multiple interface that is usually used in the automation of home. The home and building security system includes security modular, appliance controller module, fire fighting robot, television security device, GSM modem, remote supervise computer and appliance control module.

Industry personal computer is the main controller of the fire fighting robot. In order to control the mobile robot we order the command that acquire sensor data and programmed the supervised remote system with the visual basic. Security information can be received by the robot from the interface of the wireless RS232 and a generate user interface is designed for the computer control of the fire fighting robot.

In the results of the experiments the users will control the mobile robot with the help of the RF controller, remotely supervise computer and supervised control. Obstacle can be avoided by the robot using IR sensors as well as ultrasonic sensors as per the fusion method of the multi-sense. Two flame sensors can be used to know the source of the fire and fight it with the help of the extinguisher. We are also planning to design an obstacle detector in the future modular using the IR sensor and ultrasonic sensor along with the fusion of the algorithm.

For getting more quick and easy environment map in the outdoor and indoor we need to combine the laser finder . Usually a home provides safety of the security of factory, office building and laboratory is necessary to the life of human and we have also created a multi-sensor security based system that includes a robot for fire fighting in the intelligent building we design a fire fighting robot that comes with an extinguishers. 50cm, 80kg and 130 cm are the respective shapes.

Introduction:-

The main objective of this paper is to design a device which can test the electronic components accurately. In this paper we will discuss the testing of electronic components and how to repair them. A multi meter like device is designed by using a 8051 micro controller. By using this we cannot know the operational parameters of the device but we know only whether the device is working or not.

Micro controller working:

We will select an AT89C52 microcontroller which comes under the family of 8051. It is an low power and high performance 8 bit cmos microcontroller. The special feature of this microcontroller is that it has 8kb of internal flash memory which is not available in most of the microcontrollers. It is a powerful and highly flexible for the design of embedded control applications. It is a 40 pin device in which 32 pins can be used for input and output purpose and it has 256 bytes of ram. It has idle mode which halts the normal execution and allows the interrupt to continue execution.

Testing process:

An IC555 timer is used to generate a pulse which is used for testing the electronic component. The pulse is fed to the input line of the micro controller. A control unit is present in the circuit so as to adjust the pulse frequencies accordingly. At the output line of the micro controller we connect the electronic components to check its working. We can see the output values in the led. By using this device we can check the working of transistors and diodes. The present available multi meters have only specific capability of checking only diodes or transistors. We cannot know the operational parameters of the components so cannot know at what point of value the component cannot work in the circuit. Thus we can conclude that this device is high performance capable and low cost when compare to that of available multi meters.

An circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
This project is the related with the automation of currently available circuit breakers.
