US military spy drones

A small insect or a mosquito over your ear may now be much more than simply annoying. Those could easily be micro drones which now come in a swarm of bug-sized flying spies.

In an effort to create a hard-to-detect surveillance drone that will operate with little or no direct human supervision in out of the way and adverse environments, researchers are mimicking nature.  

The University of Pennsylvania GRASP Lab showed off a network of 20 nano-quad rotors capable of agile flight, which could swarm and navigate in an environment with obstacles.

This is another step away from bulky heavily armed aerial vehicles or humanoid robots to a much smaller level of tiny remote-control devices. While current drones lack manoeuvrability, can’t hover and move fast enough, these new devices will be able to land precisely and fly off again at speed. One day the military hope they may prove a crucial tactical advantage in wars and could even save lives in disasters. They can also be helpful inside caves and barricaded rooms to send back real-time intelligence about the people and weapons inside.

A report in NetworkWorld online news suggests the research is based on the mechanics of insects, which potentially can be reverse-engineered to design midget machines to scout battlefields and search for victims trapped in rubble. 

In an attempt to create such a device, scientists have turned to flying creatures long ago, examining their perfect conditions for flight, which have evolved over millions of years.

Zoologist Richard Bomphrey has told the British Daily Mail newspaper he has conducted research to generate new insight into how insect wings have evolved over the last 350 million years. 

“By learning those lessons, our findings will make it possible to aerodynamically engineer a new breed of surveillance vehicles that, because they are as small as insects and also fly like them, completely blend into their surroundings,"the newspaper quotes him as saying.

The US Department of Defense has turned its attention to miniature drones, or micro air vehicles long ago.

Green House Effect

Green  House Effect

Today I am telling about Green House Effect. I think every one is familiar with this word.
In recent years, there have been many alarming reports that the worlds climate is undergoing a significant change. All there’s reports provide strong evidence that world temperatures are increasing day by day. This increase in global warming is caused by increased amounts of carbon dioxide around the earth. Most climatologist  believe that The green house effect is the likely cause of this Global warming.
What is Green House Effect??
It is the gradual warming of the air surrounding the earth as a  result of heat being trapped y environmental pollution. This is exemplified by the destruction and burning down of topical rain forests, by traffic that clogs up city streets the rapid growth of industry, the use of chlorofluorocarbons (CFCs)  in packing and manufacturing commercial products. The use of detergents such as washing powder and washing up liquid  and so on. The oceans are also said to effected because of human waste and because of pollution caused y  industrial waste products, oil seeping from damaged super tankers and from other maritime disasters. However ,the main culprits for global warming are carbon dioxide gas, produced by  the burning of fossil fuels and forests, and pollutants such as methane and chlorofluorocarbons.

Climatologists predict that midway through the next century  temperatures may have risen y as much as 4.c.This could catastrophically reduce mankind’s ability to grow food, destroy or severely damage wildlife and wilderness, raise sea levels and thereby flood coastal areas and farmland. The alarming news about Bangladesh is that as a result of the rise of the sea level the lower southern part of the country may One day go under water.

Electronic Contact Lenses Tested Successfully in Real Live Eyes

 

Information In Your Eye University of Washington

 

The Back in 2009, we wrote about a contact lens in the works that displayed visual feedback right before your eyes, Terminator style. Well, two years and a few months later, Professor Babak Parviz has a working model. He has given the new lens to rabbits, and reports complete success.
The device's display has only one pixel, but serves as a working proof-of-concept for developing more complex information lenses. A useful device would need hundreds of pixels at least, to display a short email or text message.
The lens harvests energy from an external source using an antenna and has an integrated circuit to store the harvested power and transfer it to a transparent sapphire chip with a single blue LED. Unfortunately, while the range of the display was about one meter in free space, that range was reduced to about two centimeters when it was placed on the eye.
Another of the challenges facing the creation of a Terminator-style eye display is that the minimum focal distance of a human eye is only a few centimeters. This means that information displayed on a contact lens would appear blurry. To address this, the researchers used thin Fresnel lenses to magnify the display.
More research is needed before we'll be able to read text on our eyeballs though. "We need to improve the antenna design and the associated matching network and optimize the transmission frequency to achieve an overall improvement in the range of wireless transmission," said Parviz, co-author of the study. "Our next goal, however, is to incorporate some predetermined text in the contact lens."
