In one exemplary embodiment a storage library system for storing and retrieving media devices is provided where media drives may be added modularly to the storage library. In addition, a wiring member connects the printing element board to the contact board, a first terminal is configured to be electrically connected to the printing element board, and a second terminal is configured to not be electrically connected to the printing element board, with both terminals disposed on one edge of the contact board. The presence of the hollow space moves the club head center of gravity back and down, making it easier to get a golf ball airborne. When the attaching body is attached to the non-contact IC card, the sub-antenna is capacitively coupled to the main antenna. When the base station receives the uplink multicast message, it broadcasts the multicast message to all of the CPEs identified in the multicast message including the originating CPE. In another embodiment of the system, a radar system is disclosed that predicts future atmospheric conditions by solving the spectral flow equation.
