Abstract: A method of generating a pixel stream from an image comprised of pixels which each have a pixel value. The method comprising storing the image in a memory; determining, for each of successive sub-intervals, that pixel that is to be displayed by a light beam within said sub-interval; for each of successive sequences of one or more successive sub-intervals for which the same pixel has been determined: retrieving the pixel value of said pixel from the memory once and appending the retrieved pixel value N times to the pixel stream. Further disclosed is a projection system using this method.

Abstract: A method of generating a compressed data stream from an uncompressed data stream with red, green and blue sub-streams of red, green and blue colour values of an image, comprising, for each of a number of sub-interval which together form a time interval: Determining, in each sub-stream, at least N?1 sets of successive equal colour values and run-lengths indicating the numbers of colour values in the sets; and generating a data packet composed of one colour value from each set and their respective run-lengths; which data packet forms the compressed data stream for said time interval. Further disclosed is a projection system using this method.

Abstract: An electrodynamic acoustic transducer is disclosed, which comprises at least one coil with a coil wire being wound around a loop axis and a magnet system being designed to generate a magnetic field transverse to a longitudinal extension of the coil wire and transverse to the loop axis. Furthermore, the electrodynamic acoustic transducer comprises a membrane, which is fixed to the at least one coil and to the magnet system or to a frame/housing of the electrodynamic acoustic transducer. In addition, the electrodynamic acoustic transducer comprises a suspension system, which is fixed to the at least one coil and to the magnet system or to said frame/housing. In detail, the suspension system is fixed to the at least one coil in a region of a side wall of the at least one coil, which is oriented parallel to the loop axis.
