A system for efficiently converting computer graphics images to film images with accurate color management is described. A first opening is provided in the fitting part, in which one end of the seat belt can be attached by means of a loop which is guided through the first opening. The fiber composite reinforcing material is fastened inside the body. The rover station uses the synthetic reference phases with actual or virtual reference positions for determining a rover position having an added positional error controlled by the synthetic offset vector. Data transfer is in response to a request initiated by a bus master on the primary I2C bus.
