摘要： A three-dimensional adjustable ceiling suspension for a surgical microscope includes a first platform for holding the surgical microscope and a second platform connected to a ceiling disposed above and in spaced relationship to the first platform. Six extendable connecting elements interconnect the two platforms. Six lower articulating joints connect the connecting elements to the first platform and six upper articulating joints connect the connecting elements to the second platform. The lower articulating joints are disposed on the first platform along an imaginary first circle and the upper articulating joints are disposed on the second platform along an imaginary second circle. A plurality of drive units are connected to corresponding ones of the extendable connecting elements. A computer-supported drive makes it possible to freely select the position of the surgical microscope as well as realize a rotation and inclination about an imaginary fixed point lying in the center of the object field. The position control of the surgical microscope takes place via a coordinate drive of the longitudinally extendable connecting elements between the two platforms.

摘要： The invention relates to an arrangement for test mark positioning in spheric perimeters particularly for use in ophthalmological examinations. A semi-spherical perimeter screen has a central portion upon which a fixed mark is projected by a double projector the back-projection of which is indicated upon a visual field chart which permits recording of said back-projected fixed mark. A further projector connected to the displaceable visual field chart carrier produces discrete test marks via light cables around the central portion of said screen. Thus it is feasible to continuously detect the visual field of a patient's eye by cooperation between the patient's eye, the fixed mark and the discrete marks and by respective displacements of the projectors and hence the marks involved.
