safety stories

See this bike helmet? No? That's because it's invisible. No, really, it is: that hefty collar that the bicyclist (or whatever) in the above pic is wearing contains a helmet-shaped airbag that deploys on demand to save your skull, and spends the rest of its time out of the way and looking fashionable.
Having to shoulder a wounded comrade is never a question for soldiers, but having a method to do it more efficiently in close combat has been a needed innovation. A new device called an Injured Personnel Carrier (IPC) has now been designed to replace the old over-the-shoulder method by creating a sling — or human backpack — to free up a soldier's hands to navigate evacuation.
The new Volvo V40 proudly offers the world's first production airbag designed not for you or your passengers, but for pedestrians. Now, when you smack into people with the temerity to think that they have the right of way on roads (roads are for cars!), it'll be a much more enjoyable experience for everyone concerned. Or at least, more enjoyable than the alternative.
Unless you live in a fantastic and coordinated city like Portland, Oregon, you're likely familiar with the phenomenon of idiotic traffic lights that conspire to turn red just as you approach to make way for zero cars coming the other way. It's not just annoying, it's also bad for the ol' environment, and intelligent traffic lights could make a big difference.
I've spent a lot of time in small aircraft, and nothing (short of a wing falling off) scares me more than getting into a spin. Good pilots can recover from most stalls and spins given enough altitude, but it's still a very dangerous situation to be in, which is why it's a great idea to design an airplane that sucks at getting into spins in the first place.
