The sun may cause local residents to experience television programming outages in the next couple of weeks, EPB and Comcast officials said.

“Twice a year, sun alignment causes brief programming outages to all cable and satellite providers,” Jim Weigert, vice president and general manager for Comcast Chattanooga, said.  “This phenomenon is called a ‘sun outage,’ and it happens every early spring and again in fall. Unfortunately, this is an unavoidable occurrence that happens to all providers. The disturbance should be minimal, and it does not affect local broadcast stations.”

AT&T leaders couldn’t be reached Monday for comment.

EBP leaders notified customers through a crawling screen message on the Read more…

GPS Jammers In Action

North Korean mobile jammers

September 13, 2011: The U.S. recently revealed that one of its RC-7C reconnaissance aircraft was forced to land last March 8th, after a North Korean GPS jammer disrupted the aircraft’s navigation system. All that had previously been revealed about this was that, from March 18th onwards, North Korea had been directing a GPS jamming signal across the border, and towards the southern capital, Seoul. The jamming signal could be detected up to a hundred kilometers south of the DMZ. The North Korea GPS jammers are based on Read more…

Electronic skin tattoo has medical, gaming, spy uses-Mark of the Beast?

August 12, 2011 Comments off

A hair-thin electronic patch that adheres to the skin like a temporary tattoo could transform medical sensing, computer gamingand even spy operations, according to a US study published Thursday.

The micro-electronics technology, called an epidermal electronic system (EES), was developed by an international team of researchers from the United States, China and Singapore, and is described in the journal Science.

“It’s a technology that blurs the distinction between Read more…

Psychologists reveal how you really feel about video games

Two lecturers at the University of Huddersfield have uncovered new research that contradicts a wide stream of consciousness in the media.

Drs Simon Goodson and Sarah Pearson, who both lecture in Psychology, have revealed how playing a sporting video game is more emotionally evocative than a violent one.

Comparing brain activity from participating gamers, the team compiled data for the differing genres of video game to see how certain events in the game stimulate the player.

As Simon explains, the idea for the experiment derived from greatly over-exaggerated media scoops, suggesting violence is stimulated by aggressive video games:

“There was an assumption among reports that because a game Read more…

NASA warns of global catastrophe post upcoming ‘huge space storm’

July 31, 2011 Comments off

NASA has warned of a once-in-a-lifetime ‘space storm’ after the sun wakes ‘from a deep slumber’ sometime around 2013, causing ‘20 times more economic damage than Hurricane Katrina’.

Senior space agency scientists believe that the super storm would hit like ‘a bolt of lightning’ and damage everything from emergency services’ systems, hospital equipment, banking systems and air traffic control devices, through to “everyday” items such as home computers, iPods and Sat Navs.

And unless precautions are taken, it could cause catastrophic consequences for the world’s health, emergency services and national security.

“We know it is coming but we don’t know how bad it is going to be,” Dr Richard Fisher, the director of NASA’s Heliophysics division, said in an interview with The Daily Telegraph.

He, however, said that preparations were similar to those in a hurricane season, where authorities knew a problem was imminent but did not know how serious it would be.

“I think the issue is now that modern society is so dependant on Read more…

Electro-pulse cannon stops cars in their tracks

Today’s cars are so full of computerized electronics, one serious electromagnetic pulse could stop any car built after the mid-’70s in an instant. Canadian company Eureka Aerospace might be able to do that with its High-Powered Electromagnetic System (HPEMS). It’s a suitcase-sized electromagnetic pulse (EMP) cannon that immediately disables a car or truck from 656 feet away without hurting the driver or innocent bystanders.

This EMP cannon is said to be ready for a demo next month. So far, the prototype is too unwieldy to place in a police car, but the idea is to shrink the device to the size of a handgun. That will make it easy to mount in police helicopters, cars, and military vehicles, potentially putting an end to deadly high-speed chases, and Read more…

Power-grid experiment could confuse electric clocks

Traffic lights, security systems and computers may be affected by frequency change as well

WASHINGTON — A yearlong experiment with America’s electric grid could mess up traffic lights, security systems and some computers — and make plug-in clocks and appliances like programmable coffeemakers run up to 20 minutes fast.

“A lot of people are going to have things break and they’re not going to know why,” said Demetrios Matsakis, head of the time service department at the U.S. Naval Observatory, one of two official timekeeping agencies in the federal government.

Since 1930, electric clocks have kept time based on the rate of the electrical current that powers them. If the current slips off its usual rate, clocks run a little fast or slow. Power companies now take steps to correct it and keep the frequency of the current — and the time — as precise as possible.

The group that oversees the U.S. power grid is proposing an experiment that would allow more frequency variation than it does now without Read more…

On June 7th, Dr. C. Alex Young from the NASA Goddard Space Flight Center woke to an email from a friend saying, “I have never seen anything like this before.”  There are many things happening around us that we have not seen before, but when it happens on the sun certain people take notice. On the 7th the sun produced a prominence eruption and Dr. Young had never seen such a spectacular event, which luckily did not affect the Read more…

Cape Town – The Space Weather Centre has warned that the sun is undergoing some instability, which has implications for electronic communications.

“There is a very active area on the sun as rotated onto the invisible solar disc. This active area has got the potential for more flaring for the next five to six days,” space weather forecaster Kobus Olckers of the Space Weather Warning Centre at the Hermanus Magnetic Observatory told News24.

He said that communications and electronic systems might be affected.

“The internet could be a little slower for the next week or so and especially long distance communications.”
