The present invention provides methods for address and name discovery for Ethernet entities. A high-chromatic flaky pigment of which the entire surface of the flaky substrate coated with a metal oxide having an interference color is further coated with a semi-transparent thin metal film to enhance the interference color of the pigment. The top box is disposed at an upper part of the symbol display device and has an illumination target disposed on a front face and a plurality of visual recognition targets disposed therein. The deceleration magnitude is substantially smaller than the acceleration magnitude, and the deceleration interval is substantially longer than the acceleration interval, to thereby attenuate acoustic noise when unlatching the actuator arm. In combination these traits set \u2018Sabani Blue\u2019 apart from all other existing varieties of Geranium known to the inventor.
