An apparatus, consisting primarily of colored, dyed stretchable materials arranged solely to form display indicia, is constructed to fit onto, and substantially conform to the complex three-dimensional curvilinear shape of, a mirror housing of a motor vehicle exterior mirror. A base station corresponding to a first sector to communicate with a wireless terminal and a base station corresponding to a second sector to start communication with the wireless terminal due to movement of the wireless terminal or the like transmit a terminal identifier acquired from the wireless terminal, a time and a sector identifier to a base station control part. The interior surfaces cooperate with each other to minimize turbulent fluid flow through the respective nozzle. Where a first property is arranged upstream of a second property in the binding graph, the first property is more authoritative than the second property. In an example, the example method may be performed by an operating speed detection apparatus.
