A switch fabric is disclosed that includes a serial communications interface and a parallel communications interface. The apparatus includes a hub that may be attached to an antenna by one or more fasteners. The LCD layer and the capacitive sensing layer are bonded together via the bonding layer, and are positioned in the receiving space. Power may be applied to release the silver ions into the tissue. Further, the controller is so configured as to change the operation mode of the recording apparatus to a failure-state mode when the ultraviolet light irradiation unit has been diagnosed as a failure by the failure diagnostic unit. Moreover, the recognition element is to provide a positioning opening concavely at the side edge of a sheet-body, and the positioning opening is tiny.
