Abstract: A method for manufacturing acoustical elements, includes providing a first fibre component in a form of mineral wool and a second fibre component in a form of bicomponent fibres having a core with a thermoplastic outer layer, mixing the first fibre component and the second fibre component, for provision of a mixture, shaping the mixture into single layered tile shaped elements whereby the mixture is compressed with a compression ratio to a compressed state, and fixating the single layered tile shaped elements in the compressed state for obtaining the acoustical elements.

Abstract: A computer implemented method for determining an airborne and/or aerosol pathogen risk exposure includes determining an acoustical parameter for a portion of a building, recording, using a microphone in a mobile electronic device located in the portion of the building, sound pressure level over time originating from speech in the portion of the building, and determining the airborne and/or aerosol pathogens risk exposure as a function of the recorded sound pressure over time and the determined acoustical parameter.

Abstract: A method is for installing a ceiling system attached to a structural ceiling surface. The method includes illuminating, in sequence and by a projector, different subsets of a set of optical sensors separately arranged in a known distribution pattern on the structural ceiling surface. Each optical sensor of the set of optical sensors is arranged to output a temporal signal indicative of a level of illumination. The method also includes determining an image plane relative to the projector based on the known distribution pattern of the set of optical sensors and the outputted temporal signals of each of the optical sensors, and displaying, by the projector, an image indicative of installation locations of the ceiling system at the image plane.

Abstract: The claimed invention describes a method of preparing an installation of a 3-dimensionally extending false ceiling or wall. The claimed method includes calculating format, position and orientation for each individual flat tile in the suspended ceiling or wall, associating each individual flat tile with a unique tile identity, producing the individual flat tiles according to the calculated format, providing respective flat tile with the tile identity of respective tile, and providing a representation of the 3-dimensionally extending suspended ceiling or wall including an association of the position of respective flat tile with respective tile identity.

Abstract: An acoustic and illuminating ceiling panel includes a layer of acoustic absorbent material, the layer including a main inner face intended to be pointed toward the inside of the room, and light sources on the main inner face that is optionally covered by a voile fabric and/or coated, with a paint, wherein the light sources include organic light-emitting diode (OLED) modules with a luminous efficacy greater than or equal to 60 lm/W, and wherein a number and size of the OLED modules are adapted so that the ceiling panel provides an acoustic absorption coefficient ?w greater than or equal to 0.7.

Abstract: The present invention relates to a surface forming system intended to be supported by a structural ceiling and/or a wall of a room. The surface forming system comprises a first tile and a second tile, each tile comprising a front major surface, an opposing back major surface and at least one edge surface extending along the perimeter of the tile and connecting the front and back major surfaces, a first connecting member and a second connecting member, each comprising a tile connector and a pivot connector, wherein the tile connector of the first connecting member and the second connecting member are connected to the first tile and the second tile, respectively, and wherein the pivot connector of the first and the second connecting members are pivotably connected to each other such that the tiles are foldable relative each other. The invention further relates to a method for installation of a surface forming system supported by a structural ceiling and/or wall of a room.

Abstract: The disclosure relates to a method of preparing an installation, to a method of installation of a false ceiling or wall, to a tile for use in such a false ceiling or wall and to a false ceiling or false wall. The method of preparing an installation comprises: calculating (202) format, position and orientation for each individual tile in the suspended ceiling or wall, associating (202; 206) each individual tile with a unique tile identity, producing (300) the individual tiles according to the calculated format, providing (301) respective tile with the tile identity of respective tile, providing (302) a representation of the suspended ceiling or wall including an association of the position of respective tile with respective tile identity.

Abstract: A label assembly includes a backing of release material, a main label of label stock with adhesive substantially covering the bottom face of the main label, and first and second die cuts formed in the main label and backing respectively. The first die cut defines a secondary label within the main label, and the second die cut forms a first removable segment of the backing which overlaps the first die cut. The adhesive exerts a greater force on the first removable segment than does the rest of the backing so that when the main label is removed from the backing the first removable segment detaches from the backing and remains with the main and secondary labels. A tab integral with and extending outwardly from the secondary label is also exterior of the main label. When the main label is applied to a package, the secondary label does not stick to the package because of the presence of the first removable segment of the backing.
