Abstract: A foldable building system module (FBSM) comprising an integrated deployable modular building system. The foldable building system module comprises prefabricated panels connected by hinges which allow the panels to be unfolded from a flat pack geometry to an unfolded, erected or deployed geometry. An actuating mechanism can be integrated in one or more of the panels and, by applying load to one or more of the panels, allow for automated erection of the module. Two or more of the FBSM's can be connected in series to provide a building system.

Abstract: A prefabricated modular composite structural panel comprising a composite structural floor system. The structural panel comprises timber panels rigidly connected to steel stiffening elements aligned in the direction of span between supporting elements. By assembling multiple prefabricated panels in a modular array and adding concrete, a composite concrete floor system can be created which is adaptable to any building geometry. The timber panel acts in composite with the steel stiffening elements to function as formwork in the temporary condition with minimal or no shoring. In the permanent condition, the steel stiffening element is used to reinforce the concrete slab, and the timber panel can act in composite with the concrete slab to meet strength and serviceability requirements where permitted by code. Methods for connecting steel to timber components as well as methods for connecting panels to supporting beams are also disclosed.

Abstract: The invention relates to a device (2) and to a method for characterizing an ultrashort laser pulse. Furthermore, the invention relates to use of a self-contained optical assembly in a device (2) for characterizing an ultrashort laser pulse. The device (2) comprises an imaging optical element (4) configured to image the incident laser pulse (6) in a direction of a straight line (L). A first optical element (10) is configured to apply predetermined varying group delay dispersion on the line focused laser pulse. A non-linear optical element (14) is configured to generate a second harmonic laser pulse (30). An optical grating (20) generates a diffraction of the second harmonic laser pulse, which is imaged on a flat sensor (24). A processing unit (36) determines a best fit for the captured image thereby calculating a frequency spectrum and a spectral phase of the laser pulse.
