Abstract: The invention relates to a mobile loudspeaker apparatus for playing back sound. Mobile loudspeaker systems are often disadvantageous in that they have a poor sound quality or require equipment for a good sound quality that is not easy to transport. A loudspeaker apparatus which firstly provides a good sound quality and secondly is also easily transportable is desirable. Previously, these two requirements were often mutually exclusive. By way of a bistable membrane, or a membrane that is stable in more than two states, said membrane being coupleable to the loudspeaker apparatus, it is possible to manage the balancing act between good transportability and a good sound quality of the loudspeaker apparatus. The bistable membrane can be changed from a stable operating state into a stable transport state. By way of a slight pressure at both ends of the bistable membrane, the latter can be rolled up and consequently changed into the transport state.

Abstract: Algorithms for improved and more efficient rendering of three-dimensional images for use with holographic display systems. These algorithms include creating layers orthogonal to a viewing direction, the separate layers representing different depths in the image. The layers are created based on knowing the color and depth of each point in the image. Each layer then goes through an FFT process until the information for each layer is represented as a diffraction pattern. A holographic lens is then applied to the diffraction pattern of each layer. This lens will cause that layer to appear, in a hologram based thereon, at a different depth than the other layers. The layers, each with their separate lenses, are then coherently summed up and when applied to a suitable portion of a holographic display system (e.g., an SLM), a hologram can be created for that view. A tiled array of such holograms can be combined together by the holographic display system.
