Abstract: The invention relates to a method for compensating deviations in a deforming operation between two beams of a press, comprising of arranging one or more compensating element at a suitably chosen location in the press, detecting the deviations and moving the compensating element(s) relative to the beams by (electro) mechanical means during the deforming operation such that the detected deviations are compensated. The compensating elements can be moved here to an over-compensating position prior to the deforming operation and pressed out of their over-compensating position during the operation by the load on the beam, wherein each compensating element exerts an adjustable resistance force on surrounding parts of the press. The compensating elements each can be pressed stepwise to a position compensating the detected deviations during the deforming operation. Piezoelectric actuators can be used to exert the resistance force and/or to move the compensating elements.

Abstract: A density meter for slurry which is transported through a pipe, the density meter including: a pipe part; flexible pipe couplings arranged on either end of the pipe part; a force sensor for measuring a force in the direction of the at least one degree of freedom between the pipe part and a fixed point; an accelerometer arranged on the pipe part for measuring the accelerations of the pipe part in the direction of the at least one degree of freedom; and computing means for computing the density of the slurry in the pipe part on the basis of the volume of the pipe part, the force measured by the force sensor and the acceleration measured by the accelerometer.

Abstract: The invention relates to a linear motor with a control system for the translator which is provided with a function-approximator for approximating a function related to the movement of the translator for the purpose of determining the control signal. The function-approximator operates in accordance with the “Support Vector Machine” principle.

Abstract: Vibrational movement between the top of a lens and a main plate on which the lens is mounted is reduced by attaching between the lens and the main plate a lens support which detects relative movement between the lens and the main plates using piezoelectric sensors and compensates for that movement to reduce vibration using piezoelectric actuators which are in series with the piezoelectric sensors. The control signal which is generated to actuate the actuated piezoelectrics is generated by a controller.
