Patent AT-E534103-T1 (AT)
Inventor: XIE FENG

Abstract: A method and apparatus for high quality soft shadows for area lights in cinematic lighting for use in computer graphics, such as computer enabled animation. The method is an extension of traditional shadow maps, so it has the advantage of image based shadow methods; the complexity of the present method is independent of geometric complexity. It uses multilayer translucent shadow maps, which can be used to produce high quality soft shadows for scenes with extremely complex geometry, fur, and volume objects. Instead of the traditional sampling and filtering of shadow maps, the present method computes the shadow factor by ray tracing the multilayer translucent shadow map. The result is soft edged shadows of quality similar to that achieved by conventional stochastic ray tracing, but at much lower computational cost.

Abstract: The present invention relates to a method for the manufacture of a high-tensile-strength light waveguide with a plastic layer on the optical fiber, in which a hardenable polymer precursor stage is applied to the optical fiber. Uniform, thick layers are produced in a single operation in a process comprising applying an oligomeric and/or polymeric polyaddition or polycondensation product to the optical fiber from a solution and subsequently irradiating with actinic light and/or performing a thermal treatment. The polyaddition or polycondensation product is made from a carbocyclic or heterocyclic compound which carries two functional groups suitable for addition or condensation reactions, and a diamine, a diisocyanate, a bis-acid chloride or a dicarboxylic acid. The carbocyclic or heterocyclic compound has in a position adjacent to the functional groups partially ester, amide, urethane or urea groupings which may be of an unsaturated nature. The light waveguides made by the method according to the invention are suitable particularly for purposes of optical information transmission.

Abstract: In an arrangement embracing an internal combustion engine and transmission, intended in particular for use in motor vehicles, the crankshaft is split on the side of the flywheel (6) facing the engine and the crankshaft sections are interconnected via a torsionally elastic intermediate member (9). The crankshaft section (5) carrying the flywheel (6) may be seated in a bearing (4) disposed in an intermediate flange rigidly connected with the transmission housing (1). Further, the housings (1, 2) of the engine and the transmission may also be connected via elastic elements (31). This arrangement of torsionally elastic elements reduces considerably the transmission of torsional forces to the transmission and makes it possible to substantially reduce the idling speeds of motor vehicles and to put up with the torsional vibrations thereby created because they are no longer transmitted to the transmission and do not, consequently, give rise to noises which are transmitted to the car body through the transmission, its housing and other components of the drive train.

Abstract: A printing mechanism is described comprising a housing (12, 14) in which a plurality of type carriers (20) are disposed which are in a drive connection with coaxially disposed setting wheels (16) each having a center bore. In a space formed by the center bores of the setting wheels a setting shaft (42) is axially displaceable and rotatable. By axial displacement the setting shaft can be brought into a drive connection with each of the setting wheels. On the setting shaft an actuating knob (48) is disposed with the aid of which said shaft can be displaced and turned. In the housing a display indicator means (26, 27, 29) is disposed displaceably parallel to the setting shaft; said means is connected to the setting shaft in such a manner that the latter turns relatively thereto but can be displaced axially only jointly therewith. The display indicator means makes it possible to recognize the type carrier which can be adjusted in the respective axial position of the setting shaft. The connection between the setting shaft and the display indicator means is formed by a substantially circular cap ( 64) which is mounted with a hub (62) on the setting shaft and on the edge of which the display indicator means is secured.
