1. Monitoring human vital parameters using fuzzy logic:
In critical care, patients are surrounded by a multitude of devices for monitoring, diagnostics, and therapy. These devices include patient monitors to measure and monitor human vital parameters, therapeutic devices to support or replace impaired or failing organs and also to administer medications and fluids for the patients. In this special environment the complexity of biological systems makes traditional quantities approaches of analysis inappropriate. There is an unavoidable substantial degree of fuzziness in the description of the behavior of biological systems as well as their characteristics. Fuzzy logic provides a suitable basis for the ability to summarize and extract from masses of data impinging upon the human brain those facts that are related to the performance of the task at hand. Therefore, this approach may be very suitable for intensive care medicine, where experience and intuition play an important role in decision making. This paper surveys the utilization of the fuzzy set theory in medical sciences in general, as well as on the basis of two concrete fuzzy applications.

Now a day’s people have their own vehicles to reduce their journey time. And hence there fore they always prefer to drive fast, but a driver won’t be conscious in his driving always which is the main cause of an accident. But actually there are many ways for cause of accidents irrespective of our project concept; here we are implementing a project that avoids the rear end collision. Actually we planned this for trains. But a demo model is expensive and time bounded with various problems. Hence here we adopted it for vehicles. This kit monitors the vehicle or the obstacle that it is in front of our vehicle. /if the distance between these two is large enough, then the kit allows the driver to go with full acceleration. But once the distance between the vehicle and the obstacle is considerably reduced, it applies dynamic breaking. So as to maintain a smooth follow on. The project uses a microcontroller and an IR or ultrasonic link for calculation of distance. The ultrasonic is the feasible one, but little costlier. But it is negligible when considered with a cost of a living being.

26. Can implementation in LPC 2129 ARM7TDMI:

CAN is a broadcast, differential serial bus standard for connecting electronic control units (ECUs).The CAN bus may be used in vehicles to connect engine control unit and transmission, or (on a different bus)to connect the door locks, climate control, seat control etc. Today the CAN bus is also used as a field bus in general automation environments; primarily due to the low cost of some CAN controllers and processors. The devices that are connected by a CAN network are typically sensors, actuators and control devices. A CAN message never reaches these devices directly, but instead a host-processor and a CAN controller is needed between these devices and the bus. If the bus is free, any node may begin to transmit. If two or more nodes begin sending messages at the same time, the message with the more dominant ID (Which has more dominate bits i.e bit 0) will overwrite other nodes’ less dominant message remains and is received by all nodes. Here we implement a can communication between two can ports. We will be reading the data from the adc and will pass through the can port. The result is displayed in the LCD.

The robot consists of wireless camera, which is capable of capturing live signals and transmit them to a remote location wirelessly. The robot is controlled using RF signals; the RF signals are encoded in order for source communication. The user should guide the robot with the use of the keypad provided to him. The camera connected with the robot continuously scans the image and transmits it wirelessly. The image can be received in the television which is placed few meters away from the camera. The controlling of robot is done with the help of famous ht12d and ht12e decoders – encoder pairs accompanied with RF module. The project is designed with Atmel 89C51 microcontroller.

Automatic Electric phase change over
Project Cost: 5000/-
Abstract:

The project is much applicable wherever the single phase UN interrupted electrical supply is much essential. Here we just use a three phase line to power a single phase load; the project is much applicable for irrigation pumps in the farming areas. When any one phase of three phases fails it automatically turns the line towards the available phase and powers the irrigation system without interruption. The project uses the opto coupler for sensing the availability of the power supply in the individual phases, and at once if it notes that the power failure in the phase in which load is running presently, it automatically switches the load to the load to the currently available phase using the relay. Thereby ensuring un-interrupted power supply for the specified load.

Working:
The project senses the input voltage via the Optocoupler and in case of power failure automatically Changes to the next phase.
The demo is shown via a small relay connected to the microcontroller.
The single phase driven initially by a phase and then the phase is powered off. Then the microcontroller automatically changes to the nest available power supply.

Microcontroller based auto change over switch.

ABSTRACT:
This microcontroller based auto change over switch is mainly adopted in industrial and consumer premises where the loads is shared evenly if there is any overload or get failed.

CONTENTS:
The project includes the signal conditional, microcontroller, and change circuit.

The models are:
1) sensing circuit
2) microcontroller unit
3) change over relays

PROPOSED PROJECT:

This project is industrially authorized to change the load from one phase to other phase thus avoiding strain over the central grid.

This project sensing circuit monitors the supply continuously when there is a dip, overload or failure in the supply input. The microcontroller gets the input from sensing circuit and acts as per the conditions. If the supply fails the project initiates the alarm circuit so that the person knows to switch on the generator. The circuit checks for the next line to be switched every time before its changes the supply.

WORKING:
Our project is Automatic Changeover Switch, which automatically changes between the two available supplies. It has three inputs and one output. In some industries there is a need to automatically change between the two available supplies so that the industry can easily share the load and will not cause much strain over the central grid. It automatically changes over to the next available supply in a fraction of second. It the both input supply got failure then the circuit associated with switch produce sound to signal the operator to ON the Generator (i.e. the emergency supply)

The Switch will automatically change the supply at the presetted time. And the circuit every time before switching it checks for the supply at the next line to be switched, It will switch over to the next line only it is live otherwise it maintains the supply with the next line. The main advantage of this switch is that we need not manually change supply every time when any one of the supply got failure. Thus our project will greatly reduce the time consumed in the manual changeover and also reduce the stop in production in the industries. By adopting Micro controller the switching speed will be greatly reduced and the reliability will be improved.

There is also a provision that facilitate the user to enter his own time at which he wants the circuit to switch between the supplies. And the No supply Circuit associated with the switch produces sound when both line got dead thus it alarms the operator to switch ON the Generator (The Third Supply).
Block Diagram:


ADVANTAGES:
1) Strain in central grid is reduced,
2) Overload in individual phases is eliminated.
3) Indication to switch on the generator.
4) Time consume to manually change over the supply is greatly reduced.
5) Switching speed is very high due to microcontroller.
UPGRADATION:
1) The status of the supply can be displayed to the control room.
2) Automatic generator ON system when supply gets failed.
