An article has a surface, at least a portion of which has a local radius of curvature of about 1000 nm or less. When 3-color LED lamps 13R, 13G, 13B of the LED light source 12 are lit, red, green and blue rays emitted from respective LED lamps enter the scatterplate 11 where they are scattered and mixed to produce white light LW which goes out from the entire surface of the scatterplate 11 to illuminate the entire rear surface of the transmission type liquid crystal panel 10. If the access point is operating using power over Ethernet, it adjusts the operation of its radios, gracefully degrading those radios from both radios operating in 3\xd73 mode, to a first radio operating in 3\xd73 mode and a second radio operating in 2\xd72 mode, to both radios operating in 2\xd72 mode. This component is typically mounted or installed into a circuit board. The invention also provides a disc-holding page that snaps into the lid of the container to allow a second disc to be stored. During discharging operations, a plurality of discharging heads are selectively arranged about the extended path-length of metal-fuel tape so as increase the rate at which electrical power is powered from the system.
