A stereomicroscope has a rotary mirror to switch an optical path of a beam from an objective optical system between a normal optical path A and an image optical path B. A print file having a MICR portion and a non-MICR portion is built based upon IRD data. In the second step, the phenol and acetone produced is reacted, preferably without intermediate purification, in the presence of a cation exchange resin catalyst that includes a cation exchange resin and a mercaptan or mercaptoalkanoic acid promoter to produce BPA. The wireless communication device determines a total transmission power for at least one component carrier and allocates transmission power to at least one antenna. Both techniques also incorporate an adaptation algorithm for developing and maintaining digital models of 1 Mbs 1553 signals received from multiple 1 Mbs 1553 terminals on a bus.
