Embodiments of the present invention provide improved water fill capabilities, improved coffee baskets, and improved steam diverting and management features for coffee makers used on board passenger transport vehicles. A sun gear drives a planet carrier via at least one planetary gear, which rolls on a fixed internal-geared wheel. Alternatively, opposing sound waves may strike the pellicle on the same surface of the pellicle as the background sound waves, may be provided with substantially the same frequency and amplitude in opposing phase to the background sound. A dielectric is formed to surround a top surface and sidewalls of the metal nitride node.
