With the advent of the Satellite TV age our eyes have got accustomed to seeing satellite dishes on roof tops, near windows in apartment buildings and even those compact dishes on some cars and camper vans. These are actually a kind of nuisance to the surrounding considering the fact that they spoil the beauty of a structure and not to mention the amount of dirt they collect over time and people don't even bother to clean them.

But with a new technology developed by a recent PhD graduate from The Netherlands University of Twente it is days over for the dish antenna. Marcel Van de Burgwal has designed a microchip that allows for a grid array of almost flat antennas to receive satellite signals. With the inspiration from the LOFAR project which uses an array of antennas located across the northeast Dutch countryside linked together to form a virtual radiotelescopy dish.

India (DRDO) to Develop its Own Operating System for Security

Low cost Webcams to monitor vital signs

Technology has always been bringing about improvements in our way of life and our heath care systems. In the future the most important tool for a doctor the stethoscope will just turn redundant.   How??

How it works?

The system works by simply putting a person in-front of a low cost camera like a webcam and gives exact and accurate information about pulse rate of the person.The system works through a complex video imaging system called  "Non-contact, automated cardiac pulse measurements using video imaging and blind source separation". Developed by Ming-Zher Poh, Daniel J. McDuff, and Rosalind W. Picard.
