TK, that's interesting. Once you can think it through a bit more, I'd love to hear your educated opinion.
Here's the company website:
Hövding - Den osynliga cykelhjälmen
Quote:
The airbag is deployed by sensors – accelerometers and gyros – that pick up a bicyclist's abnormal movements in the event of an accident. The sensors then send a signal to the gas inflator to inflate the airbag.
When Hövding is switched on, the sensors are constantly monitoring the wearer's movements. A bicyclist's movement patterns are divided into two different categories:
Normal movements: All bicycling in the city and on main roads, as well as all the normal movements you make before, during and after a bicycle ride such as running up and down steps, locking your bicycle, braking suddenly, giving way, pumping the tyres, etc. are defined as normal movements. Normal movements won't cause Hövding to inflate.
Abnormal movements: The movement patterns of a bicyclist in an accident are defined as abnormal movements. In an accident, a bicyclist's movements are completely different from those seen in normal bicycling. That's why the airbag is only triggered by accidents*.
To be able to distinguish between these two categories of movements, we've spent the past few years gathering data on the movement patterns of a large number of bicyclists in everyday bicycling situations. We've also re-enacted all known types of bicycling accident and recorded the movement patterns of bicyclists in these accidents. We staged fatal bicycling accidents using crash test dummies, while other bicycling accidents were re-enacted by stunt riders, male and female. We put all these movement patterns into our database and have developed a unique, patent pending, mathematical method for distinguishing between normal and abnormal movements. This method combined with the sensors is Hövding's brain.
*Hövding will only be deployed if the bicyclist makes an abnormal movement in an accident. This means that Hövding will not protect bicyclists from objects falling directly onto their head from above. However, this type of bicycling accident is extremely rare.

I love the last sentence.
