Abstract: Fixation arrangement adapted to releasably fix a wind turbine tower segment (4) to a support (3) of a transport vessel (20), comprising at least two fixation means (2), wherein each fixation means (2) comprises a base member (6) fixed or to be fixed to the support (3), a lever arm (8) connected to the base member (2) and pivotable around a pivot axis (9), and a tensioning means (13) for clamping the lever arm (8) with a clamping section (10) against the tower segment (4), wherein the tensioning means (13) comprises at least one tensioning element (14) supported relative to the base member (6) and movable from a non-clamping position in a clamping position and back, wherein the tensioning element (14) directly or indirectly interacts with the lever arm (8) which is pivoted into a clamping engagement of the clamping section (10) with the tower segment (4) when the tensioning element (14) moves from a non-clamping position into a clamping position and which is released when the tensioning element (14) moves back

Abstract: An autofocus actuator for camera modules and control method thereof, the autofocus actuator incorporating a shape memory alloy wire as actuating element, at least 4 spheres as sliding aids, and including a return elastic element mounted between an autofocus housing and a lens carrier and exerting a force only in the optical axis direction.
