A semiconductor integrated circuit includes a ROM having bit lines extending in a first direction in a first layer. For example, a conferee placing a conference on hold may generate on hold music, which may be identified by a nuisance detector. The present invention further contemplates assays for detecting such viral variants which assays are useful in monitoring anti-viral therapeutic regimes. Then, the management information thus generated and the stream are recorded onto a storage medium. The controller identifies the transmitter and tire on the first wheel based on the identification signal transmitted from the transmitter on the first wheel and determines, for each of the transmitters, whether the transmitter and the associated tire are located on one of the right-side wheels or one of the left-side wheels based on the rotation direction signal transmitted from the transmitter.
