Abstract: Subject matter of this invention is an apparatus to enable the tridimensional shape of a partially reflecting anatomical surface of a human body, specifically the cornea, to be spatially located. The apparatus, which is based upon a computer and a TV camera, comprises a body (11) made of a transparent material (PERSPEX.RTM.) wherein a conical hole has been drilled. Circular, frusto-conical, alternatively transparent and opaque, retro-illuminated, reference lines are provided in the conical surface of the hole. Furthermore, the apparatus comprises a photoelectrical couple (17, 18) (an emitter: IRED or LED; and a sensor: photodiode or phototransistor) arranged at diametrically opposed points of the external base of the cone, such that when the cone is moved close to the eye to be analyzed, the apex of the eye intercepts the sight line between the emitter and the sensor at a pre-established distance from the cone.

Abstract: A device for projecting light spots onto a surface, comprising a device for generating and concentrating light, a pierced member which is movable before said device and endowed with means for selecting the hole to be aligned with the light, an assembly of lenses and mirrors and a projection head for projecting light onto a surface, and a shutter member, which controls the projection of the beam itself, in which device means for orienting said pierced member around the vertical axis passing through the center of the selected hole and means for orienting the same pierced member around the horizontal axis passing through the center of the selected hole are provided; the orientation and position of the pierced member, as well as the selection of the hole and of the orientation of the projection head, being achieved by a computer.

Abstract: A mechanical device for positioning the head of a patient in electromedical apparatuses, which device comprises a chin-rest and a headrest element held by two vertical rods, in which device mechanical means for bringing the same to a position displace of about 15.degree. to the right or to the left with respect to the center of the hemispherical dome of the electromedical apparatus, means for fastening the position of the patient's head, means that allow said fastening means to be adjusted and fastened by acting on one or on the other indifferently of said rods and mechanical means for adjusting the vertical position of the chin-rest are provided.
