Abstract: An air transport unit comprising a composite board. The composite board comprising an anode layer and a cathode layer of an electrically conducting material. The anode layer and cathode layer are separated by an insulator of an electrically insulating material. The composite board further comprising an electric component in electrical connection with the anode layer and the cathode layer. The air transport unit further comprising a carrier board, wherein the composite board and the carrier board each have a duct forming surface, which carrier board and composite board are arranged so that an air duct forms between the duct forming surfaces.

Abstract: The present invention relates to a UV lamp having an axial dimension normal to a cross-section having a cross-sectional area with a ratio of the axial dimension to the cross-sectional area in the range of 0.1 cm/cm2 to 1000 cm/cm2. The UV lamp includes a first axial conductor separated from a second axial conductor by an electrically insulating material and a light emitting diode (LED) capable of providing light at a wavelength in the range of 100 nm to 400 nm, which LED is mounted to emit light from an outer surface. The invention also relates to a method of sterilising a surface using the UV lamp.

Abstract: An electrical supply module including a composite board including a first and a second layer of an electrically conducting material separated by an insulator, which first layer forms an outer surface including a first electrical contact site, the composite board having a recess, allowing access to a second electrical contact site at the second layer, the recess having a coupling portion and a coupling unit having a complementary coupling portion allowing releasable coupling with the coupling portion of the recess, a first electrical contact area and a second electrical contact area, wherein coupling of the coupling portion and the complementary coupling portion establishes electrical connection from the first and second electrical contact sites to the first and second electrical contact areas, respectively. The electrical supply module provides a flexible device that allows freely adding and removing various electronic components to the composite board.
