Abstract: The disclosure regards a method and a system for assisting a person in assessing an environment. The method includes selecting a set of one or more entities present in the environment, obtaining coordinates in the environment and extents of each entity of the set, estimating a location and shape of each entity of the set on the basis of the obtained coordinates and extends of the respective entity, determining an area of interest on the basis of the estimated location and shape of each entity of the set, evaluating the area of interest with respect to one or more variables of interest in order to evaluate a deviation between a current state of the area of interest and a target state, and communicating the deviation from the target state to the person using coherent stimuli for stimulating the person's body.

Abstract: An endoscope system has imaging optics and includes at least one adjustable optical element. A working instrument is positionable relative to the imaging optics. A displacement measuring device is designed for detecting a distance covered by the working instrument with its positioning. A control device adjusts the optical element in dependence on a detected displacement.

Abstract: An optical instrument has an outer shank (15) with a viewing window (31) arranged near the free shank end and a handle part (1) at the other end of the outer shank. An opto-electrical a transducer (26) is rotatably arranged within the outer shank, and is attached on an inner shank (12) which is rotatably mounted within the outer shank. Actuation means (10) for rotating the transducer (26) are provided in the outer shank. An axial bearing is provided between the outer shank and the inner shank (12). Moreover, a spring element impinging the inner shank (12) with force in the direction of the axial bearing is provided.

Abstract: An endoscope, in particular a mediastinoscope, in which the handle and the optics guided therein form an inseparable unit and which includes a first and second spatula-like part which can be separated from one another in the longitudinal direction. An adjusting mechanism is provided which permits a separation, a fastenable displacement parallel to the axis and a fastenable pivoting of the two parts relative to one another. In particular by way of the pivotability an expansion of a body cavity to be visually examined or which is to undergo therapy by way of introduced auxiliary instruments is made possible according to requirements.
