Abstract: A metering unit for flowable solids including an outlet nozzle of flexibly elastic material having at one end an inlet opening for fixing on the outlet of a storage container and at its other end a slot-shaped outlet opening formed between two opposite sealing lips and elastically preloaded in the closed position and can be transferred against elastic preloading to an open position as a result of compressive forces. The slot-shaped outlet opening is elastically preloaded into its closed position by a separate clamp made from a flexibly elastic material, which can be applied releasably to the outer circumference of the sealing lips, wherein the legs of the clamp rest on the outside of the sealing lips in the mounted state and are elastically preloaded in the direction in which they are close together and can be moved elastically away from one another as a result of the compressive forces.

A processes for manufacturing apparatuses for supplying energy to an active eye implant can be based on head geometry data of a user.

Abstract: A device for supplying power to an active ocular implant in an eye of a user can include a spectacle lens with a first main surface and a second main surface, a light source, and an optical arrangement which is configured to input couple light from the light source into the spectacle lens and output couple said light from the first main surface of the spectacle lens to the user. The optical arrangement can include at least one diffractive element which is arranged in the spectacle lens. Each of the at least one diffractive element can have an associated first end and an associated second end. The associated first end and the associated second end each can have a different distance from the first main surface and/or each have a different distance from the second main surface.

Abstract: An apparatus for supplying energy to and/or communicating with an eye implant by means of illumination radiation is provided, wherein the apparatus comprises a positioning unit, which sets an illumination position of the eye of a user, an optical input interface, by means of which the illumination radiation is suppliable to the apparatus, and an illumination optical unit, wherein the illumination optical unit focuses the supplied illumination radiation in such a way that a focus with a lateral extent of at least 0.1 mm in air is present and such that, when the eye of the user is in the set illumination position, the illumination radiation enters into the eye as a convergent beam such that the focus lies within the eye.

Abstract: The invention relates to a method for examining an eye of a patient by the patient themselves by means of an ophthalmological apparatus, said apparatus having front optics and an apparatus pupil. According to said method, the patient positions the ophthalmological apparatus relative to the eye, a measure of the deviation of the pupil of the eye from the apparatus pupil is determined, and a pupil correction signal is produced depending on the measure of the deviation, said pupil correction signal specifying a direction and/or a degree of the deviation and being output to the patient. The patient can use the pupil correction signal for repositioning in relation to the ophthalmological apparatus with a smaller deviation.

Abstract: Methods and devices for visualising an implant in a retina are provided. A 2D image of the retina is taken and OCT scans of the retina and implant are carried out. Based thereon, the implant and retina are visualised.

Abstract: A method is provided for reconditioning a turbomachine vane cover plate, by a forming apparatus. The vane having a mounting portion, an airfoil extending radially outward therefrom and a vane head connected to the airfoil. The vane also having a cover plate connected to the vane head, bulged in a direction opposite to the root. In a first analysis step, dimensions of the vane in relation to the cover plate are determined in respect of predefined reference points. If, thereafter, forming of the cover plate seems necessary and possible based on comparison of measurement values from the analysis step with predefined dimension values, the bulged cover plate is formed, at least essentially pressed smooth, by pressing by the forming apparatus in a forming step. After the forming step, the cover plate is re-treated in one or more follow-up steps. An apparatus is also provided for carrying out the method.
