D-Air wearable airbag
Dainese has signed a memorandum of understanding with the International Ski Federation (FIS) to bring its D-Air wearable airbag technology to Alpine slopes. The project is currently in early stages of testing where the dynamics of ski racing are being investigated in order to tailor the existing motorcycle-specific technology to the needs of ski racers.
The system packs in three accelerometers, three gyroscopes, a GPS and a 2 gigabyte internal memory and without any physical connection to the motorcycle, it can deploy a high-pressure airbag around the rider in just 45 milliseconds when crash conditions are detected. This detection capability is the key to the system - it can differentiate between an imminent fall and normal riding, but to transfer the technology to skiing, an entirely new set of data needs to be collected and the triggering algorithm reworked.
