A ridge-waveguide filter with a signal input port at a first end and a signal output port at a second end contains a cascade assembly of metal-bounded ridge-waveguide sections with interspersed metal-bounded evanescent-mode coupling regions, and also contains low-loss ridge-waveguide port coupling networks to impedance-match the ends of the assembly to respective signal-port reference impedances. In one embodiment, the elevator assembly may include a foot extension configured to contact a reference surface, and a substantially planar one-piece bracket configured to support the foot extension and slidibly couple the foot extension with a housing of the projection device, wherein the bracket enables the foot extension to extend and refract relative to the housing of the projection device. The housing is devoid of openings. The measurement device associated with the automated inspection station is configured to examine the different medications and generate a measured medication value for the different medications. An engine clutch is connected to an internal combustion engine as the oil pressure value in the cylinder decreases. The biomaterial can be a remodelable material that strengthens andor supports the vessel walls.
