  • Publication number: 20080089537
    Abstract: A loudspeaker system for an aircraft cabin for passengers, having a support structure, which includes multiple flexible flat elements, forming the internal walls of the cabin, fastening devices for fastening flat elements to the support structure, so that the flat elements may oscillate. At least one acoustic driver is connected to one or more flat elements, to induce a bending movement in the one or more flat elements. The particular flat element may oscillate as an acoustic diaphragm. The acoustic driver has a film-shaped piezoelectric exciter, which is bonded flatly to the flat element. The flat element bonded to an exciter has a first cover layer, a second cover layer, and a core layer between them. The core layer is subdivided in a plane parallel to the first and second cover layers by a horizontal incision in at least one predefined area.

  • Publication number: 20070189549
    Abstract: An audio system for an aircraft passenger cabin and a method for controlling such an audio system for providing passengers with information programmes, in which multiple loudspeakers are each disposed at a predefined loudspeaker location in the aircraft cabin, and an audio signal having at least one audio channel is reproduced via the loudspeakers wherein the at least one audio channel is output by a central processing unit to the multiple loudspeakers in the aircraft cabin via a bus system having multiple distribution units and multiple cabin units.

  • Patent number: 6839406
    Abstract: A method and an apparatus for detecting items in objects, such as in luggage, wherein a detector apparatus, functioning as a second detector is divided into a lower testing stage and a higher testing stage. In the lower testing stage, the coordinates of the object location are determined, and subsequently, a diffraction apparatus is moved to this location in the higher testing stage. In particular, X-ray diffraction can be employed to determine the explosive material of the item in the object. The diffraction apparatus comprises a collimator/detector arrangement, which is disposed to be adjusted height-wise and laterally in the higher testing stage, with a laterally-adjustable X-ray source, which is synchronized with the collimator/detector arrangement. The collimator/detector arrangement preferably has only one collimator and one detector. The collimator preferably has a conically-expanding ring slot, which a predetermined angle ?M of a scatter radiation.

The collimator/detector arrangement preferably has only one collimator and one detector. The collimator preferably has a conically-expanding ring slot, which simulates a predetermined angle &THgr;M of a scatter radiation.

  • Patent number: 6542578
    Abstract: A diffraction apparatus (10) for determining crystalline and polycrystalline materials of an item in objects, preferably in luggage, having a collimation/detector arrangement (11) and an X-ray source (12) and which is mounted to be adjustable in an X-ray testing machine (13). The collimation/detector arrangement (13) is adjustable in height relative to the X-ray source (12), and the two are also laterally and synchronously adjustable via respective adjustment elements (5,6). The collimator (13) has a conically-expanding round slot (15), which simulates a predetermined angle (&THgr;M) of a scatter-beam path.

  • Patent number: 6532276
    Abstract: A method for determining the material of a detected item in objects, especially explosives in luggage, using X-ray diffraction. In this method, wherein scatter radiation deflected at the crystal-lattice structure of the material is measured and compared to characteristic energy spectra or diffraction spectra of various explosives, the absorption by the material influences the X-ray diffraction spectrum, so that information is missing, and inaccurate conclusions may be drawn regarding the material. To improve this method, the primary beam of an X-ray source is used for measuring the absorption. The beam passes through the material, and, from the absorption, an average atomic number of the material is determined, and this additional information is used for the identification of material known by comparing the recorded spectra with diffraction spectra.
