  • Patent number: 8096229
    Abstract: In order to detect a lack of coffee beans in a grinder unit of a coffee maker, a method is suggested in which the level and/or the spectrum of an oscillation generated by the grinder unit during its operation is measured. The level of the oscillation and/or the nature of the spectrum are used to decide whether or not coffee beans are present in the grinder unit. Preferably, the level of oscillation of the housing of the coffee grinder unit is monitored. If the level changes by more than a preset value and/or falls below a reference value, it is decided that coffee beans are lacking.

  • Patent number: 8079443
    Abstract: A trim panel for an aircraft interior includes a first sound attenuating layer, a structural layer and a second sound attenuating layer. The structural layer is coupled to the exterior sound attenuating layer, and has an exterior side and an opposite interior side. The structural layer defines a plurality of passages that open to both the exterior side and the interior side so as to minimize radiation of noise due to a hydrodynamic shortcut created by each of the passages across the structural layer. The second sound attenuating layer is coupled to the structural layer and has a high sound absorption characteristic. The second sound attenuating layer is configured to be disposed adjacent to the aircraft interior.

  • Publication number: 20100140550
    Abstract: A method is presented that makes possible the labelling of powders that can be applied as building material in a layer-additive manufacturing method such as a selective laser sintering method. To this effect the powder is mixed with at least one salt of a metal of the rare earths, wherein the salt has the property that it shows a luminescence when being irradiated with photons having a wavelength outside of the visible spectrum or with particle radiation. Thereby, parts that have been manufactured by means of the layer-additive manufacturing method can be identified with regard to the manufacturer, the place of manufacture or the manufacture date.

  • Publication number: 20090017220
    Abstract: A method for a layer-wise manufacturing of a three-dimensional object has a first step of providing a layer of a material in powder form or a liquid material on a support or a layer that has already been solidified at selected positions previously and a second step of directing a focussed photon or particle beam (8?) selectively at selected positions of the layer. In the process in the second step the photon or particle beam is selected such that it brings about a change of the absorption of the material when hitting the layer. After the termination of the second step a third step is carried out, in which the layer is irradiated by means of electromagnetic radiation (18?) such that the material is homogenously solidified at those positions of the layer that correspond to the cross-section of the object to be formed.
