ALEXANDRIA, Va., Nov. 11 -- United States Patent no. 12,467,430, issued on Nov. 11, was assigned to VESTAS WIND SYSTEMS A/S (Aarhus N, Denmark).

"Wind turbine rotor blade pitch control for tower fatigue reduction" was invented by Alexander Duncan Giles (Oporto, Portugal), Jesper Sandberg Thomsen (Hadsten, Denmark) and Christian Jeppesen (Horsens, Denmark).

According to the abstract* released by the U.S. Patent & Trademark Office: "Adjusting pitch of the wind turbine rotor blades to reduce fatigue of the wind turbine tower. Flap loading sensor data is received for the rotor blades, and a flap loading vector in a rotor coordinate frame of the wind turbine is obtained. The flap loading vector is transformed to obtain first and second mutuall...
