Yup, Tristar-500 had ACT, Active Control Technology. I think it was because the -500ft had a longer wing so needed this system to keep the structural weight down. A320 had the LAF, 787 has active spoilers, ailerons & a load alleviation function using the inboard flaps. The inboard and outboard flaps are separated in flight. They move out automatically, depending on load. They also move in the cruise to reduce drag.
