Abstract: A space control system and a detection system are disclosed. The detection system is configured for distinguishing a moving living object, e.g. a human being, from a moving machine object in a space. The system comprises an imaging apparatus configured for producing a plurality of images over time of at least a part of the space. The images have a good spatial resolution. The system also comprises a processor configured for determining motion signals of the moving living object and the moving machine object from the plurality of images. The processor is configured to transform the motion signals to a frequency domain and distinguish in the frequency domain between motion signals related to moving living objects and motion signals related to the moving machine objects. Accordingly, the system is enabled to detect at least one of the living object and the machine object in the part of the space on the basis of the distinguished motion signals.

Abstract: The present invention relates to a lighting device (100), which comprises a structure of interconnected sleeves (110) and a light emitting arrangement (140) arranged inside the sleeves. The structure forms a polygon mesh and light sources (116) on the light emitting arrangement (140) can be positioned by the structure so that the problem of glare can be reduced. The present invention also provides a sound-absorbing, flexible and collapsible structure which can be used in e.g. large scale architectural panels, horticulture and phototherapy devices. The lighting device (100) can be produced by connecting the sleeves (110) with thermoplastic material or by sewing.
