US Patent 11584046 Patterned inflatable membranes

Inflatable membranes may include a pattern layer, a fluorescent layer, and a window, the pattern layer comprising an inner surface and an outer surface, the pattern layer comprising a pattern on the inner surface of the pattern layer, and at least a portion of the pattern layer formed by a transferrable material transferred from a casting plate to the inner surface. The fluorescent layer may include an inner surface and an outer surface, the inner surface of the fluorescent layer abutting the outer surface of the pattern layer and comprising a fluorescent material which, upon receiving of light, causes the fluorescent material to emit fluorescent light and causing the pattern to be detectable by a detector. The window may include a transparent material that spans an aperture formed in a distal end of the inflatable membrane.
