Translation:
Armand Torre is the man who designs our kites. We owe him the invention of the Bird mode on our SeaKite kites. An ingenious invention that allows to reduce the power of the kite during the launch and recovery phases.

The Birdkite is a kite specially designed for towing boats, it is launched in single line thanks to its capacity to keep the auto-zenith and then to fly it in 4 lines.
My comment: it is a great invention which also would allow to solve (automated) takeoff and landing for flexible kites, power (reel-out) phase in crosswind flight by being fully deployed, depower (reel-in) phase by being reduced, and also overspeed protection.
