Abstract: A power semiconductor module includes a power semiconductor die arranged on a power substrate, a housing enclosing the power semiconductor die and the power substrate, wherein an interior volume formed by the housing is divided by interior walls into at least a first compartment and a second compartment, wherein the power semiconductor die is arranged within the first compartment, a first encapsulation material encapsulating the power semiconductor die and at least partially filling the first compartment, and a second encapsulation material different from the first encapsulation material, the second encapsulation material encapsulating the first encapsulation material and at least partially filling the second compartment, wherein the first encapsulation material is arranged within the first compartment but not within the second compartment.

Abstract: A light device for curing a dental composition, comprising a light-source, a housing, a passive heat sink, first and second thermal pathways enabling heat transfer between the light source and the heat sink as well as between the heat sink and the housing. The first thermal pathway is dominated by thermal conduction, and the second thermal pathway is dominated by thermal radiation and thermal convection. The invention helps to provide an inexpensive and compact design of the device.

Abstract: A device is provided having a housing with a housing wall consisting of a non-transparent plastic with an outer surface and an inner surface; and an operating mode display unit with at least one light-emitting element which is/are located inside the housing, underneath the inner surface of the housing wall. The housing wall has at least one recess in the area of the light-emitting element and the light intensity of the at least one light-emitting element is adjusted in such a way that in its light-emitting mode, said at least one light-emitting element is only optically perceptible in a localizable manner through the housing wall in this area.

Abstract: The invention relates to a device for storing and dispensing a flowable composition. Said device comprises a first (1) and a second film (2), a dispensing zone (4), a first chamber (5), containing a first substance (A) and a second chamber (6), containing a second substance (B). Said chambers are interconnected by a transition zone (3) that can be selectively opened. At least one of the films is deep-drawn in the region of the chambers and at least one of the films is pre-formed in the region of the second chamber, in such a way that once the device has been activated by opening the transition zone, the first substance can to a great extent be completely transferred to a second chamber, increasing the volume of said chamber as a result.

Abstract: The invention relates to a radiation device comprising a housing, a single light-emitting unit, and a light-absorbing unit which is provided with an inlet opening and a reflector element. Said reflector element extends across the entire distance between the light-emitting unit and the inlet opening of the light-absorbing unit.

Abstract: The radiation device has an array (11) of light-emitting diodes (12) providing light beams which are directed onto a focus region (20) at the input end of a light conductor (18), used for directing a focused light beam onto the radiation point. The light-emitting diodes are supported in a planar holder (19) at different inclination angles, for providing a light cone illuminating the light conductor input end from their output beams.

Abstract: The invention relates to a light wave converter assembly, comprising a light guide and a light wave converter, comprising a converter substance, which converts a part of the incident light into light of a longer wavelength, whereby the converted light is guided together with the unconverted light through the light guide to an exit port.

Abstract: A mixer capsule, especially for the production of dental materials, comprising a cartridge (10) that is closed on one end by a piston (12). The piston has a hemispherical recess (12) that forms a chamber and is closed off from the main chamber (18) of the cartridge (10) by means of a separating device (16). A body (20) that is provided in the initial state in the main chamber (18) is used to facilitate the mixing process and to penetrate the separating device (16) at the beginning of the process, whereby the main chamber (18) and the subsidiary chamber (17) form a single mixing area. At the end of the output process, the body (20) enters the hemispherical subsidiary chamber (17) and acts as a displacer.
