Abstract: A device for measuring reference points in real time during lithographic printing includes a light source providing an exposure beam; a light modulator modulating the exposure beam according to an exposure pattern; a measurement system configured to measure a position of a number of alignment marks previously arranged on a substrate; and an exposure optical system comprising a control unit. The exposure optical system delivers the modulated exposure beam as an image provided by the light modulator onto the substrate. The exposure system control unit is configured to calculate the orientation of the substrate based on the position of the alignment marks and control the delivering of the modulated exposure beam relative to the calculated orientation of the substrate.

Abstract: An actuator system for actuating a valve in a subsea environment comprises a valve spindle that is arranged to be coupled to an electric motor. To provide for power to the motor, at least one local electrical storage unit is provided. The system also includes a control unit comprising switching means for controlling the power to the motor. The control unit includes an intelligent processor and is arranged to receive signals from external sensors measuring a number of external and internal parameters, The actuator is preferable housed in a modular cage for easy replacement.
