Methods and kits for identifying RNAs and DNAs associated with an RNA or DNA binding protein via a detector specific for the binding protein or protein bound thereto which is linked to an oligonucleotide capable of directing the synthesis of cDNA copies of RNA or DNA that are in close proximity to or in the vicinity of the bound detector are provided. The Front Air Chamber takes in air then compress it so that we get a very high sound pressure {sound wave} output, and the Speaker Side Air Supply ducts supply all the air the Front Air Chamber needs. Preferably, said search request message can be used to obtain one or more pieces of information, among the mode information of one or more devices detected while the procedure for the physical connection is performed and the information on a network to which one or more said detected devices belong.
