Abstract: An active vibration isolation and damping system (11) comprising a payload (12) that has to be isolated or damped, a vibration sensor (14) for detecting a vibration of the payload, an actuator (15) for moving the payload relative to a bearing body (13) supporting the payload, and a controller (16) for providing the actuator with a signal that is representative for the vibration. The system provides a solution for the tilting problem by applying a vibration sensor that has a low stiffness connection to the payload (12) for rotation along an axis (17) perpendicular to the gravitational force (18), and a high stiffness connection to the payload (12) for the vibration detectable with the vibration sensor.

Abstract: A method of assembling a wall from prefabricated wall parts, wherein edge surfaces of two wall parts are placed against each other leaving a gap there between, and wherein first and second sealing members are included in the gap to each act between said edge surfaces of the wall parts, which sealing members extend in a longitudinal direction of said edge surfaces and are spaced apart in a transverse direction of said edge surfaces to define a cavity there between, and wherein said cavity is filled with a solidifying liquid, such that the solidifying liquid acts on a cavity facing surface of each sealing member and presses the sealing member into engagement with at least one of the edge surfaces.
