C. Cobb, Jr., U.S. Patent No. 4,906,070
F30. Cobb '070 describes a thin film that is said to totally internally reflect light. (ZX 2013,
abstract). Generally, the thin fihn has a structured surface on one side and a smooth surface
opposite the structured surface. The structured surface consists of a linear array of miniature
prisms. (ZX 2013, col. 1, lines 56-62). Cobb specifically describes a film having about 70
prisms per inch as having suitable flexibility such that the fihn can be curled into a cylinder while
maintaining a smooth continuous accurate surface without breaking. (ZX 2013, col. 3, lines 60
68). The film can be used in a variety of applications, such as a collector of solar energy or as a
light conduit. (ZX 2013, abstract).
D. Usui, et al., U.S. Patent No. 5,210,797
