In order to match up individual recordings in a sequence of recordings with corresponding items in a sequence of separately-stored auxiliary data items concerning those recordings, both the recordings and auxiliary data are time-stamped, though from different clocks. In a first embodiment, the vibration is caused by a reciprocating shuttle having a wedge-shaped member attached to it. The wireless communication device may then modify functions associated with a plurality of smart antennas based on the power or signal processing functionality and in relation to a reference design. A second pattern is formed on the reflector on the second pixel region, in which the second pattern is formed by dividing the first pattern into at least two pattern regions according to a predetermined direction and rearranging the pattern regions. The razors are substantially deposited in plurality as an array formation onto the surface of the substrate.
