Abstract: The present invention relates to an apparatus for controlling a load suspended on a cord, wherein the movable load has a controllable actuator, and a control unit is provided, which is configured to use control commands for controlling the actuator in order to predict a load countermovement to be expected, so as to compensate for and/or prevent the load countermovement by controlling at least one compensating device controlled by the control unit.

Abstract: Supporting structure (8) for curved envelope geometries in buildings consisting of support elements (4) which are each combined to form N-sided polygons (N=3,4, . . . ) which span the envelope geometry and which each enclose a planar surface element (5), and the support elements (4) of adjacent N-sided polygons each form a common node region (3) in which the support elements (4) abut, and the plane of a surface element (5) and the respective planes of the surface elements (5) of two N-sided polygons which adjoin in non-parallel spatial directions lie in different planes in at least one portion of the envelope geometry.
