Patent ID: 8113695

Claim:
A component of an actuatable apparatus, the component comprising: a substrate including an obverse surface and an opposed reverse surface, one of said obverse surface and said reverse surface defining a transparent selected area; a selectively light-transmissive opaque covering applied to one of said obverse surface and said reverse surface to selectively enable and prevent transmission of said light therethrough; said opaque covering disposed to intercept light directed through said selected area; said opaque covering characterized by first and second portions collectively defining a pattern associated with said selected area; said first portion having a first transmissivity to light to enable transmission of said light therethrough; and said second portion having a second transmissivity to light to prevent or impede transmission of said light therethrough; and an illumination source actuatable between an illuminated state and a non-illuminated state, and adjacent said reverse surface for illuminating said selected area; wherein actuation of said illumination source directs light through said first portion but not through said second portion to thereby reveal said pattern; and wherein said opaque covering renders said pattern invisible when said illumination source is in said non-illuminated state, and visible when said illumination source is in said illuminated state.
