Abstract: Described herein is a mobile device with an optical detector including: at least one illumination source adapted to generate at least one illumination pattern for illuminating an object, where the illumination pattern includes a regular and/or constant and/or periodic pattern; at least one sensor element having a matrix of optical sensors, the optical sensors each having a light-sensitive area, where each optical sensor is configured to generate at least one sensor signal in response to an illumination of the light-sensitive area by at least one light beam propagating from the object to the detector; and at least one evaluation device adapted to determine at least one region of interest.

Abstract: A tool assembly for attaching to two carriages of a carriage guide rail system; wherein the two carriages are movable along the carriage guide rail relative to one another, the tool assembly having a base and a linear actuator movable relative to the base; wherein the base has a first connector for attaching to one of the two carriages; wherein the linear actuator has a second connector for attaching to the other one of the two carriages; wherein the base has a first base portion attaching to the first connector; wherein the first base portion is arranged between at least a part of the linear actuator and the two connectors in a direction perpendicular to the carriage guide rail.

Abstract: A method for operating a steam turbine where steam turbine has at least two sub-turbines, wherein the steam turbine is paired with a steam turbine controller which has a sub-turbine controller for each of the sub-turbines, and each sub-turbine controller compares respective target values with respective actual values of the respective sub-turbine during operation in order to determine a respective control deviation for each sub-turbine.

Abstract: A turbine control unit and method for controlling a turbine, in particular for controlling the start-up of a turbine, the unit being designed as a cascade controller having a master controller and an inner controller, the master controller being a thermal stress controller for the components subjected to thermal stress.

Abstract: A turbomachine train with two shaft parts which each have a fixedly attached grooved wheel, with a first overrunning clutch, with two rotational speed sensors and with a control device. The clutch is designed to couple and decouple the first shaft part to and from the second shaft part. The first rotational speed sensor measures the rotational speed of the first grooved wheel. The second rotational speed sensor measures the rotational speed of the second grooved wheel. The control device determines the differential angle between the first shaft part and the second shaft part and accelerates the turbomachines, with an acceleration value determined on the basis of the measured rotational speeds and on the basis of the differential angle, such that the two shaft parts couple together at a predetermined target coupling angle.

Abstract: A quick acting control valve for a steam turbine is provided. The quick acting control valve includes a valve box and a control valve cone which is arranged in the valve box so as to be displaceable along its center axis, whereby the control valve cone may be brought into an open position in which the control valve cone, with its control valve cone surface is lifted off the valve box and into a closed position in which the control valve cone rests against the valve box with its control valve cone surface, and a quick acting valve piston which is arranged in the valve box so as to face the back of the control valve cone facing away from the control valve cone surface, the quick acting control valve piston, on its outer peripheral edge, always resting on the valve box in a steam-tight manner.
