An input device is provided that includes a touch-sensitive surface, and an attachment structure for attaching the surface. The VAWT has a vertical rotor and curved blades coupled to a gearbox and an electric generator. When QoS between two zones degrades, the allowable bandwidth for new calls between the two zones is lowered to a point that assists in increasing the QoS back to an acceptable level. The pressure difference between the monitored pressure in the sensor conduit tube and the pressure in the free space in the fuel tank above the surface of the remaining fuel is directly proportional to the weight of the fuel lying above the sensor conduit tube distal end. Said stops or clamping strips act on the opposing sides or comers of the pallet and fix them in a position, in which the accepting unit deposits the parcels with positioning accuracy, according to the predetermined pattern, on the pallet.
