Apparatus are provided which include a media content presenter, a media content cross-reference scanner, and a media content cross-reference presentation generator. The first chamber for the fluid medium at least partially surrounds or encompasses the stent in the holding device that may include a housing which substantially encloses the first chamber for the fluid medium. In this structure, ink remaining on the surface of the nozzle plate can be efficiently removed. The signal to noise ratio of the reverse pilot channel is raised by the base station in response to a frame error rate decrease generated by the selector component of the base station controller. The virtual system modeling engine is configured to generate predicted data output for the electrical system utilizing a virtual system model of the electrical system.
