Abstract: A micro identification system supports facile optical assemblies and components. A segment of optical fiber can comprise an identifier formed via actinic radiation. The identifier can generate a laser interference pattern that can be read through a cylindrical surface of the optical fiber to determine a code. Modified optical fibers are those fibers that have been shaped or coated to an extent beyond the demands of normal communications optical fibers. In one example, modified fibers are no longer than about two feet in length. For another example, the modified fibers can have either a non-cylindrical end face, a non flat end face, an end face the plane of which is not perpendicular to the longitudinal axis of the waveguide, an end face coated with high density filter, or an identifier on or near an end face.

Abstract: A modified fiber interlink forms an optical link between multiple channel waveguides to be mated. Multiple modified fiber interlinks can form optical paths between a multiple fibers and a multi-channel planar waveguide. Modified optical fibers are those fibers that have been shaped or coated to an extent beyond the demands of normal communications optical fibers. In one example, modified fibers are no longer than about two feet in length. For another example, the modified fibers can have either a non-cylindrical end face, a non flat end face, an end face the plane of which is not perpendicular to the longitudinal axis of the waveguide, an end face coated with high density filter, or an identifier on or near an end face.

Abstract: Waste management for people with an ostomy (ostomists), and who therefore find it necessary to wear an ostomy bag, is accomplished simply through processes, systems and ostomy tools involving versatile latent tubes. Such tools include ostomy bags, filters, connectors and conveyance vessels. The tools are particularly helpful, for example, in controlling the location and disposition of ostomy wastes (and their odors) when the ostomist performs challenging routine to unusual tasks associated with ostomy care and maintenance. The tools also help to instill confidence in the users' ability to carry on normal daily business and social activities without creating embarrassment or discomfort for themselves or others.

Abstract: Optical assembly for controlling or limiting undesirable photon entrance, reflection, departure, or appearance. A material opaque to unwanted photons can be applied to an optical assembly that would otherwise allow penetration of the unwanted photons. For example, a filter can be applied to a waveguide member. A first face surface of the filter faces toward an end of the waveguide member and a second face surface of the filter faces away from that member end. A mask adheres to one of the filter surfaces. The mask is substantially opaque in at least some selected spectral region to impact the extent to which photons in that spectral region can pass through the filter and to the waveguide member.
