An article of furniture, for example a chair, is upholstered with a sports jersey for displaying the jersey thereon. A primary ingredient of the liquid crystal display medium is a liquid crystalline composition of high-molecular liquid crystal in which molecules that can function as a liquid crystal are chemically bound to side chains of a high-molecular polymer skeleton through a flexing group. By applying these scenarios to transactional data from a variety of financial institutions, broker and investor activities causing unacceptable amounts of risk can be detected on an automated basis. An Nk-axis splitter splits the Nk-axis signal into two, one being output to outside through the ring of the Nk-axis direction while the other being output, if k<n, to a confluence with an Nk+1-axis signal, and, if k=n, to a wavelength separation filter. An imaging detector is situated to receive the spectrally spread and focused light from the interface and form an image corresponding to angle of incidence as a function of wavelength. The method also includes retrieving the first and second portions of the data in the first and second memory locations in the data memory.
