Abstract: It is desirable for the production of workpieces, which are sometimes produced by a rapid prototyping method, to be further automatable. To this end a device is provided having a laser for generating a laser beam in order to set a material, and a workpiece support which can be exposed directly to the laser. There is also provided an optical instrument for redirecting and deviating the laser beam so that the workpiece support can also be exposed indirectly to the laser. Material can therefore also be cured more easily in undercuts of workpiece blanks.

Abstract: To further automate the manufacture of hearing aid component parts that are in part produced with a rapid prototyping method, a laser beam for curing material is generated by a laser, and a workpiece support that can be directly exposed by the laser is provided. The laser beam is deflected by an optic device so that the workpiece support can be indirectly exposed with the laser. Material can thereby be more easily applied in undercuts of workpiece blanks that form the basis of the hearing aid component parts.

Abstract: A device for acoustic analysis has a first hearing device with a first sound input and a first sound output and a second hearing device with a second sound input and a second sound output. The first hearing device is in acoustic communication with the second hearing device. The first hearing device can analyze the acoustic communication and output a corresponding result. Consequently, two hearing aids, for example, can test each other, and permit a user to check hearing devices and, in particular, hearing aids in a simple fashion without the hearing aid wearer having to visit an audiologist for the test.

Abstract: A hearing aid has a hearing aid component, a brain wave signal receiver configured to receive brain wave signals, and a hearing aid controller configured to control the hearing aid component dependent on the detected brain wave signals. Therefore the hearing aid can be controlled by the detected brain wave signals.

Abstract: A device and a method for curing plastic moldings are particularly suited for curing hearing aid housings. A light source emits curing light and a holder, at least partially transparent to curing light, holds the plastic moldings. The holder has an elongate light guiding element, which is transparent to curing light, which has an emission portion for emitting curing light in a number of spatial directions, and which is formed in such a way that at least the emission portion can protrude into a convex curvature or an interior space of a plastic molding that is being held by the holder. The light guiding element guides curing light emitted from the light source to the emission portion and emits from there. The light guiding element may have a holding portion for holding the plastic molding. The holding portion and the emission portion may spatially overlap.
