Abstract: A cleaning tool for an aerosol-generating device is provided, the cleaning tool including an elongate body having a proximal end portion and a distal end portion, the distal end portion defining a recess configured to receive a heating element of an aerosol-generating device, the recess extending from an opening in a distal end face of the elongate body towards the proximal end portion of the elongate body, the distal end portion of the elongate body being provided with at least one protrusion inwardly projecting into the recess, and the elongate body further including a scraping surface at the distal end face of the elongate body.

Abstract: A solar array module system for generating electric-power, preconfigured to prevent electric blockage of the module when a physical row of solar cells malfunctions. The module includes a matrix of X physical rows and Y columns of solar cells, electrically interconnected in a plain criss-cross matrix. The columns of the physical matrix are divided into a first side, numbering YL columns, and a second side, numbering Y-YL columns. The first side includes cells that are physically inverted relative to the cells of the second side. The negative side of the cell in the 1+nth physical row of column YL is electrically connected to the negative side of the cell in the X-nth physical row of column YL+1 (0?n<X). The positive side of the cell in the Xth physical row of column YL is electrically connected to the positive side of the cell in the 1st physical row of column YL+1.

Abstract: A preferred embodiment of a magnetic connecting apparatus for connecting two units has at least one first connecting element associated with a first one of the two units and at least one second connecting element associated with a second one of the two units, the connecting elements forming a connecting pair. The connecting elements of a connecting pair each have a plurality of contacts. The connecting elements of a connecting pair make magnetic contact with one another and are rotatable relative to one another in a contacted state.
