摘要:
The present invention concerns a method of providing communication over a mobile communication network (1) and components for providing communication over the communication network (1). The network (1) includes two or more fixed nodes (2a, 2b) each operating a fixed radio cell (3a, 3b) for serving one or more user equipments (4) via a first radio interface (5a, 5b). Each of these fixed radio cells (3a, 3b) is identified by a physical cell ID (6a, 6b) selected out of a set of N physical cell IDs. In addition, the network (1) includes one or more mobile relay nodes (7) served by the one or more fixed nodes (2a, 2b) via a second radio interface (8a, 8b). The mobile relay nodes (7) each operate a mobile radio cell (9) for serving one or more user equipments (4) via a third radio interface (10). Each of these mobile radio cells (9) is identified by a physical cell ID (6c) selected out of the set of N physical cell IDs. The method includes the step of dynamically assigning a physical cell ID (6c) of the set of N physical cell IDs to the one or more mobile radio cells (9).

The invention relates to a sound distributor with symmetry of revolution. The distributor comprises two sound reflecting cups, having a convex shape which is an exponential of surface revolution about a fictitious axis. The outer surfaces of these cups are arranged in tail to tail manner. The distributor has at least one sound source positioned facing a small opening of one of the cups. Around an opening in the bottom of the second cup, the distributor also has a trumpet-shaped reflector and a cone-shaped reflector for directing sound along the axis.

The invention concerns an omnidirectional loudspeaker. This loudspeaker comprises a spherical membrane which includes spires formed of a strip (2) made of a magnetostrictive material, the spires being spiral wound according to a sphere; these spires are kept in place by an elastic support (1) so that, along with the support, they form a spherical membrane. The strip has two opposing faces (11, 12), one of which is directed towards the inside (I) of the sphere, the other being directed towards the outside (E) of the sphere, and two extremities (3, 4) situated in two diametrically opposing zones of the sphere so as to be connected to an electric control device (5) providing a signal corresponding to sound waves to be reproduced, and a device (7) for the continuous polarization of the membrane. According to the invention, one of the faces (11) of the strip (2) is at least partly coated with a thin coating (13) made of a rigid material. Invention may be applied for the diffusion of high quality omnidirectional sound waves.
