Fog screen technology

By

ABSTRACT:

INTRODUCTION:

— Fog Screen is breakthrough technology that allows projection of high quality images in the air. It is currently the only walk-through projection screen that allows for projections on a thin layer of dry fog.

— The first public demonstration of Fog Screen was in Finland in October 2002



WORKING:

— The system starts with water that is held in a large plastic container or comes from a regular water pipe. This water is drawn through a plastic tube via a small engine.

— the fog screen is an internal part of the laminar airflow, and remains thin and turbulence

— The ultrasonic transducer is used to divide the water into small and tiny water droplets

— fog is pushed down and held in place by several small fans, allowing for a consistent surface for display.

CONCLUSION:

— Nokia, one of many using the Fog Screen products, installed a number of screens to trade show entrances that showed an animation of a character walking and using the Nokia products can be used in seminars to make it more interactive

— in similar way with further advancement in technology it can be devolved as a min computer which can be used anywhere ,anytime, anyplace

Wi-vi the wifi vision

By
ABSTRACT: A new technology known as  Wi-Vi is bouncing up with a good progress.It is similar Radar and Sonar imaging..it depends on radio signals  of wifi.I monitor movements of people in closed rooms or behind a wall. Wi-Vi was created by Dina Katabi ,a professor  in MIT,and her graduate student Fadel Adib. Wi-Vi technology can detect number of humans in a closed room. Enable communication through a wall without carrying a wireless device.Identify simple gestures from behind a wall. This Wi-Vi signals uses Wi-Fi signals,as Wi-Fi signals can penetrate through walls. Wi-Vi relies on a simple hardware of 2.GHz  Wi-Fi radios small enough to be portably used.Integrated in hand held devices.Low power Wi-Fi signals are used. A Wi-Vi system constitutes-  1.Two transmitting antennas 2.single receiver. This technology is based on principle of Rada and Sonar.Radar and Sonar works on Doppler effect. This technology uses reflected Wi-Fi signals...

Brain chips

By
Introduction: Thousands of people around the world suffer from paralysis they need to depend on some one for even some basic   tasks brain chips can become  a handy at this case .Brains are made with a view to enhance the memory of human beings, to help paralyzed patients, and are also intended to serve military purposes. It is likely that implantable computer chips acting as sensors, This is like a implantable computer chip in brain. This consists of both biological and electronic term's. A chip in the Braingate system is of 100 hair thin electrodes.It senses electromagnetic signature of Neutrons.The Brain chip provides fast and reliable connection between the brain of a severely disabled person and personal computer. Braingate is a technology is a technology by which the electrical signal is exchanged by neurons within the brains are used to execute body moment .  Hardware of brain chips  It mainly consists of. Four parts ->chips: A Four ...

The truth about hacking

By
The Process of attempting to gain or successfully    gaining, unauthorized access to computer resources   is called   Hacking. Hacking is been a part of Computer for over 40 year's.The first hacker is from MIT In  the  computer  security  context,  a  hacker  is someone who  seeks  and  exploits  weaknesses  in  a  computer system  or  computer  network.  The programers prefer to refer them as crakers. This are the main reasons for hacker to hack a system. -Just for fun. -Show off. -Notify many people their thought. -Steal important information. -Destroy enemy’s computer network during the war. Hacking is mainly divided into two types - ethical hacking - unethical hacking Ethical hacking is where a person hacks to find weaknesses in a system and then usually patches them.This is Often done to protect from. Hacking Unethical hacking  is often ...
