Patent attributes
A component of an actuatable apparatus has a substrate, a selectively light- transmissive opaque covering, and an illumination source. The opaque covering is applied to an obverse surface or a reverse surface of the substrate to selectively enable and prevent transmission of light therethrough. The illumination source is adjacent the reverse surface for illuminating a selected area of the substrate. The opaque covering is characterized by first and second portions collectively defining a pattern associated with the selected area. The first portion enables transmission of light therethrough, and the second portion prevents or impedes transmission of light therethrough. Actuation of the illumination source directs light through the first portion but not through the second portion to reveal the pattern. The opaque covering renders the pattern invisible when the illumination source is in the non- illuminated state, and visible when the illumination source is in the illuminated state.
