Abstract: The present disclosure relates to a calibrated constellation simulator, a system and a method for calibrating and/or testing a star sensor assembled on a spacecraft. The calibrated constellation simulator comprises an optical device configured to project a defined star formation (IRF) of a star catalog onto a star sensor assembled on a spacecraft. Further, the calibrated constellation simulator comprises an alignment unit with a position and/or location reference (ARF) of the calibrated constellation simulator configured to detect a position and/or location of the calibrated constellation simulator in space, wherein the defined star formation (IRF) and the position and/or location reference (ARF) are in a first fixed calibrated rotation (QOSPS) with respect to one another. The calibrated constellation simulator improves the calibration of the star sensor as an independent calibration standard. The constellation simulator becomes a calibration standard.

Abstract: The present invention relates to a door system for a refrigeration device and a refrigeration device with such a door system.

Abstract: A refrigerated cabinet includes a door assembly for closing a cooling chamber. The door assembly includes a door supported by pivot bearings being configured to pivot about a vertical axis between a closed position and an opened position. Rails arranged substantially parallel to a side wall of the refrigerated cabinet are configured to displaceably support the pivot bearings of the door. The door is displaceable in the rails between a use position in front of the cooling chamber, in which the door is pivotable between the opened position and the closed position, and a parking position next to the cooling chamber, in which the door cannot be pivoted.

Abstract: A drive mechanism for a rotating body having a rotatable shaft includes a clutch to selectively transmit torque input to the shaft, a brake to slow down rotation of the shaft upon disengagement of the clutch, and an actuator to engage and disengage the clutch and brake. The clutch and brake are each mounted on a mounting member which is movable with respect to the shaft in the axial direction thereof. The actuator includes an actuator member that is slidably mounted on the mounting member and an actuator to move the actuator member from a first position, in which the clutch is engaged and the brake is disengaged, and a second position, in which the clutch is disengaged and the brake is engaged.
