A coffee machine for making a coffee beverage using pre-packed and pre-portioned coffee pouches including a brew chamber which includes a brew chamber top and a brew chamber base. The layout can be realized in a split block configuration using any number of fabrication methods, such as brazing, electroforming, and machining and is most effective when it is realized in a split-block construction, in which the waveguide components are formed in the recesses split about the zero current line. A movable shade is positionable to control the light received by the reflector. In another example, a first target layer of molybdenum-100 is surrounded, at least in part, by a second target layer of 98Mo. The second gateway determines that the SIP message should be interworked to a disconnect message. The methods determine a correlation lag value corresponding to a time shift in receiving propagation of an interference pattern traveling along a path that is subject to the turbulent air region at antennas responsive to incident electromagnetic energy.
