ASBURN, Va. (Ivanhoe Newswire) -- Traditional crash test dummies have been used since the early 1950s to help study injuries from car crashes, but there's been little change in dummy design. Now, researchers are developing smart, new dummy technology.

The day Nissa Quill was in a car accident, she was thankful her daughter wasn't in the car. "When the airbag went off, my hands and my arms took all of the blow from the airbag," Quill told Ivanhoe. Her injuries didn't take long to notice. "Pretty quickly some bruises and abrasions appeared on my arms," Quill said.
Each year, three million people are injured in car wrecks. Crash test dummies are used to study injuries on humans, but dummies aren't human-like enough to show real injuries. In addition to the steel and rubber "physical" dummies, mechanical engineers are now using new computerized dummies that are more human-like and reveal what's happening inside the bodies of the vehicle occupants during a crash.
"If you have a simulation, you can look at multiple aspects of what really went through the dummy," Pradeep Mohan, Ph.D., a senior research scientist at the National Crash and Analysis Center in Ashburn, Va., told Ivanhoe. "You can really dissect the information much closer."
During a simulated crash test, the researchers can see the cause of the dummy's injuries from various crash angles. The software also allows engineers to remove the dummy's body parts to reveal never-before-seen injury details. "Let's say you want to do a detailed study of the brain injuries … then you can just quickly switch it to a model," Dr. Mohan explained. The tests -- using computerized dummies -- are used to improve safety features in cars and build safer cars that prevent injuries better, keeping drivers and passengers safer.
At thirty-eight years old, Quill had never been in a car accident before. "So now I realize it's not that hard for it to happen," she said. Accidents will happen, but hopefully with fewer injuries. Computerized dummies are also used to design safer sports and military helmets.

Truckers often work more than 50 hours a week and can legally drive for up to eleven hours non-stop. With extra-long hours on the highway, exhaustion is a big concern. Now, virtual reality is being used to help make roads safer.
Each year, more than three million people are injured in car accidents, and every 12 minutes, someone dies in a crash. With so many cars on the road, it's a trend that's likely to continue and get worse! But now, high-tech crashes helping save lives.
Every day, weather forecasters are put to the test for accurate daily predictions. It's a hard job that gets blamed for rained-out picnics, cancelled barbecues and delayed planes; but today, our forecasts are more accurate than any other time in history.
Every year, early warnings about dangerous thunderstorms -- even tornadoes and hurricanes -- help get millions of people out of harms way before the danger comes. Now, scientists are worried about a new threat: dust storms.
There's increasing research that environment plays a key role in causing asthma attacks, but how do you know what triggers your asthma? Researchers think they may have the answer.
Blind students are about to speed up their learning curve thanks to a new "smart" pen. Did you know, just three characters of Braille take up an inch on a page? This new pen can condense that information into just one smart dot.
Dyslexia can be a frustrating condition, making it difficult for children to read. Many think it is a visual issue, but a new study using a computer game reveals the problem may not only be with sight, but also sound.
