In an embodiment a pulse sensor includes two light sources configured to emit light in a direction of a perfused tissue of a living being so that the perfused tissue scatters the light and so that the scattered light is modulated on basis of a pulse of the living being, at least one luminescent concentrator including an entry face, an exit face smaller than the entry face, and a fluorescent material arranged in a light path between the entry face and the exit face, wherein the luminescent concentrator is configured to receive at least some of the modulated scattered light entering through the entry face, convert the entered light by the fluorescent material and emit the modulated converted light from the exit face, and one light detector configured to detect at least some of the modulated converted light emerging from the exit face, wherein, in plan view, the luminescent concentrator is strip-shaped and extends perpendicular to a connecting line between the two light sources, wherein side faces of the luminescent concentrator facing the light sources are concave, and wherein corresponding side faces extend at least partially around the light sources.

A load-pulling system includes a least one belt to which a tensile load is applied. The belt is formed of a matrix and a load-bearing fiber structure embedded in the matrix and having a plurality of fibers. The belt is guided around a least one deflection device in such a way that it forms a curved section in the region of the deflection device. A dimensioning of the belt and the applied tensile load are matched to each other in such a way that, in the curved section of the belt, a zero stress line of the belt is displaced radially inward in the direction of curvature with respect to a center line of the load-bearing fiber structure by an amount of at least 25% of the thickness of the load-bearing fiber structure.
