A new Impatiens plant particularly distinguished by numerous medium to large, double, deep-pink outer petals and white to light pink inner petals with white centers, medium-green foliage with elliptical leaves, an early flowering response, floriferous throughout the summer, good rain tolerance, a medium-sized, round and bushy plant habit with good branching ability, is disclosed. The first multiplexer receives a plurality of even order signals. A signal rearranging circuit selects any two first combined signals from the two first combined signals allowing duplicate selection, and takes out any one polarization signal from each of the selected first combined signals, and performs frequency-multiplexing of the taken out two polarization signals to generate a second combined signal. The assay preferably detects a change in fluorescent intensity of a label as a function of binding affinity between the probe and target.
