Abstract: An exposure control device serves for equipping and/or retrofitting a generative layer-wise building device. The exposure control device has a first data output interface, at which control commands can be output to the exposure device. The control commands specify one of a plurality of exposure types defined by a predetermined combination of a radiation energy density to be emitted by the exposure device and a scanning pattern with which the radiation is being directed to a region of a layer of the building material. The exposure control device also includes a second data output interface at which an exposure type can be output in real time in relation to a timing of the output of a control command specifying this exposure type.

Abstract: An exposure control device (31) serves for equipping and/or retrofitting a generative layer-wise building device (1). The latter comprises an exposure device (20) which emits electromagnetic radiation (22) or particle radiation and is configured to irradiate positions to be solidified in a layer in such a way that after cooling they exist as an object cross-section or part of the same. The exposure control device (31) has a first data output interface (36), at which control commands can be output to the exposure device (20). The control commands which are output specify one of a plurality of exposure types wherein an exposure type is defined by a predetermined combination of a radiation energy density to be emitted by the exposure device (20) and a scanning pattern with which the radiation (22) is being directed to a region of a layer of the building material (15).

Abstract: An apparatus for trimming and splicing of optical waveguides is disclosed. One embodiment of the apparatus includes a holding device for holding one of the optical waveguides, a trimming device for trimming of one of the optical waveguides and a control device for controlling a movement of at least one of the holding device and the trimming device. The control device drives at least one of the holding device and the trimming device such that the at least one of the holding device and the trimming device is moved to a first position at which one of the optical waveguides can be trimmed by means of the trimming device.
