A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best wireless channels in its vicinity. Such a radio automatically detects available channels in wireless spectrum, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given spectrum band at one location. This process is a form of dynamic spectrum management.
You can use this robot for do some service jobs like bringing water.
Global warming has increased the demand and request for green energy produced by renewable sources such as solar power. Consequently, solar tracking is increasingly being applied as a sustainable power generating solution.
About this device :
Is a device for orienting a solar panel or concentrating a solar reflector or lens towards the sun. Commentators, especially in solar cell applications, require a high degree of accuracy to ensure that the concentrated sunlight is directed precisely to the powered device. Precise tracking of the sun is achieved through systems with single or dual axis tracking. In this project i will print the degree of tracking and the value of the measured power which gave from the solar cell on the LCD Screen too.

Nowadays, the application of PLC is widely known and use in this digital world PLC’s application is obviously applied at the industrial sector. Normally, the PLC’s that have been used at the industrial field is usually to control a mechanical movement either of the machine or heavy machine in order to create an efficient production and accurate signal processing. In this project, a discussion about PLC application will be explained in more details and specified.
For this project ALLEN PLC is used, which act as heart of the system and is programmed using Ladder programming. During this project sensor has been used to detect the bottle position that move along the conveyor belt at the low speed while the machine operates. The input signal that has been sent from the sensor to the PLC has being made as a reference. Signal in order to determine the output signal that exactly a same with the PLC programming language based on the user requirement.
The processes in this project:
1-Tracking the bottles
2-Utilizing the Boolean Data
3-Boxing the Broken Bottles
4- Fill and Cap the Bottles
5-Tracking the Production Numbers
The high demand of automobiles has also increased the traffic hazards and the road accidents. Life of the people is under high risk. This is because of the lack of best emergency facilities available in our country.
How the device works:
This design is a system which can detect accidents in significantly less time and sends the basic information to first aid center within a few seconds covering geographical.
This alert message is sent to the rescue team in a short time, which will help in saving the valuable lives. When the accident occurs the alert message is sent automatically to the police station. The message is
sent through the GSM module and the location of the accident is detected with the help of the GPS module. The accident can be detected precisely with the help sensors and some components.
This application provides the optimum solution to poor emergency facilities provided to the roads accidents in the most feasible way.
The advent of technology has increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back.
It can be used as a crash or rollover detector of the vehicle during and after a crash. With signals from an accelerometer, a severe accident can
be recognized. According to this project when a vehicle meets with an accident immediately sensors will detects the signal and sends it to Arduino. Arduino sends the alert message through the GSM MODEM including the location to police control room or a rescue team. So the police can immediately trace the location through the GPS MODEM.
This project provide basic data such as:
Co2 percentage on the air using CO2 sensor.
Car location .
after receiving the information. Then after conforming the location necessary action will be taken. If the person meets with a small accident or if there is no serious threat to anyone`s life, then the alert message can be terminated by the driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team.

The HPA (Heart Pulse Alarm) is a portable device that measures the pulse rate and the body temperature. If the device receives an up normal heart pulse, it will send a message to paramedics to act quickly.
How the device works:
The patient puts his index finger on a pulse sensor, and the device starts to measure it; at the same time, the patient’s hand touches a temperature sensor to measure the body temperature. These records are automatically sent to a server called “SMS Server” which they will be saved and organized there in a register. The message will be sent to the SMS server only if the values are normal, but if the device registered up normal values, the message will be sent right to paramedics.
The message in the normal mode will contain the heart pulse rate and the body temperature; the emergency mode will contain heart pulse rate, body temperature, and the patient’s location.
The message’s text in the normal mode would be:
(I am fine, my pulse rate is “….” My temperature is “….”)
And in the emergency mode would be:
(I am “Murad” I have a high pulse rate, please help me, my location is “….” My pulse rate is “….” My temperature is “….”)
I designed this device to help persons who have problems with their hearts and they lack personal assistants, and for old people.
