<p>A closure system (8) including a closure (16) moveable for substantially closing an aperture (14) in use, and an actuator (20) for at least closing the closure, the actuator being mounted by mounting means (24, 26), the mounting means including one or more measurement cells (C1, C2) for measuring, in use, parameters of the closure systems, in use the system being subjected to movement and being arranged such that it is possible to at least partially distinguish trap forces applied to the closure from acceleration forces applied to the closure as a result of the movement of the closure system by consideration of the measured parameters (Figure 2). <IMAGE></p> |
