Abstract: In one implementation, a content distribution network includes a first plurality of communication paths for Internet Protocol (IP) signals, a router providing a second plurality of communication paths for non-IP signals, and a plurality of signal sources and a plurality of signal destinations. Each signal source is linked to a respective one signal destination by a respective first communication path of the first plurality of communication paths. Each of one or more of the signal sources designated as a protected source is further linked to the respective one signal destination by a second communication path of the second plurality of communication paths. The content distribution network distributes content in one of a first mode in which the first communication path and the second communication path carry the same content contemporaneously, or a second mode in which only the second communication path carries that content.

Abstract: A series of modular fabric panels with edge zippers interconnect to form a modular window covering system custom fit by a user to cover windows of various sizes. Flexible zippers with removable zipper pulls and edge cover fabric over the zippers create a customized curtain which looks like a standard sewn seamed curtain.
