Abstract: A cabin segment of a passenger cabin of a passenger aircraft is directly adjacent a cockpit along a longitudinal axis of the aircraft and includes a cockpit bulkhead transverse to the longitudinal axis which separates the passenger cabin from the cockpit. The cockpit bulkhead contains a cockpit door, wall portions of left and right-side fuselage walls having respective cabin doors and an emergency exit region to be kept free which connects the cabin doors. The cabin segment ends level with foremost passenger seats and contains a sub-space left of the cockpit door and a sub-space right of the cockpit door. One of the sub-spaces is a vacant space between the cockpit bulkhead and the foremost passenger seats which extends to the fuselage wall and contains neither a galley nor a lavatory.

Abstract: The present invention relates to a drive unit for a joint being arranged between two arm members of a manipulator of a robotic system and for the rotatory drive of one arm member in relation to one other arm member, with a motor which drives a drive shaft, with an output element, which is connected with the one arm member and which is directly or indirectly set into rotation by means of the drive shaft, and with a circuit board, on which a sensor device for the drive as provided by the drive shaft and a sensor device for the output as provided by the output element are arranged.

Abstract: The invention refers to a method for measuring fluorescence lifetime. An excitation light radiation (12a), periodically modulated in a first frequency, is directed to a fluorescent material (20). For the measurement of fluorescence lifetime, the phase difference between the excitation light radiation (12a) and the fluorescent radiation (20a) is measured, the fluorescent radiation being detected by a fluorescent radiation detector (18). According to the invention, a correction signal (16a), periodically modulated in a second frequency, is supplied to a measuring circuit (19), and a phase drift between the emitted correction signal (16a) and the correction signal (16a) processed by the measuring circuit is measured, the phase drift being caused by the measuring circuit.
