A collapsible sun shade adapted to be used with a chair is disclosed. A method of the present invention includes forming a layer of developable anti-reflective coating over a plurality of code openings located on a substrate of a ROM device. A plurality of wettable pads is exposed within one or more of the cavities. In some embodiments, an identification and communication system comprises one or more query units and one or more response units, wherein at least one query unit comprises a first query beam source operable to emit a first component beam and a second query beam source operable to emit a second component beam. Also, streams containing organic molecules produced by the processes are described. The control circuit is configured to cause a clock signal to be provided to the buffer and the storage media at a clock rate that varies in dependence on a detected rate of the transactions received by the buffer.
