The German helmet and eyewear specialist Uvex is starting to distribute the eponymous sensor system of Tocsen, a start-up in Freiburg, Germany. Tocsen consists of a fall sensor and app to detect the crash of a helmet wearer. It enquires about the state of the fallen skier, snowboarder or cyclist, routes an emergency call to previously defined contacts and signals the crash’s location with GPS data if there is no response. The fall sensor fits any ski or bicycle helmet, and the Tocsen app is available free of charge. The electronics of the sensor are produced in the Black Forest, the casing in Nuremberg. The batteries come from Lake Constance, the packaging from Braunschweig. The Tocsen app’s servers are located in Bavari.
