ABSTRACT:
Apparatus comprising a tensing element connected at one end thereof to a supporting structure and at another end thereof to a cover, wherein movement of the cover imparts a force on the tensing element, an actuator adapted to move the tensing element, and a sensing device adapted to sense an equilibrium force position of the tensing element, wherein if the force changes the equilibrium force position the sensing device instructs the actuator to change a tension imparted by the tensing element on the cover.
