Abstract: In at least one embodiment, the semiconductor layer sequence (1) is provided for an optoelectronic semiconductor chip (10). The semiconductor layer sequence (1) contains at least three quantum wells (2) which are arranged to generate electromagnetic radiation. Furthermore, the semiconductor layer sequence (1) includes a plurality of barrier layers (3), of which at least one barrier layer is arranged between two adjacent quantum wells (2) in each case. The quantum wells (2) have a first average indium content and the barrier layers (3) have a second, smaller, average indium content. A second average lattice constant of the barrier layers (3) is thereby smaller than a first average lattice constant of the quantum wells (2).

Abstract: A mobile communication device that is outfitted with motion detection mechanisms is used to construct a viewport on audio-visual data. As the communication device is moved along a spatial trajectory, the viewport is positioned accordingly. A virtual space can be constructed such that the spatial trajectory is mapped into the virtual space and the user can navigate the virtual space by suitable movement of the communication device. Accordingly, a user can use natural body movements to navigate the virtual space through the viewport.

Abstract: The invention pertains to an improved method and apparatus for cleaving slaughtered carcasses. For being able to remove spine portions remaining in each carcass half after cleaving, it is suggested that the lower portion of each half is tipped inwardly while the upper portion of each half is moved outwardly. This implies that the spine portions in each carcass half will be pressed outwardly on the inside of the carcass half and made available to cutting means which will cut out the spine portions with a minimum of losses and without affecting adjacent muscles.
