Abstract: A system and method for providing video signals wherein the video signals from a single video source may be separately passed over two different transmission paths. Each transmission path includes an encoder, a communications channel and a decoder. The output of each communications path at the decoder provides the video signals and an alarm signal. The alarm signal indicates an error or disruption of the video signals over the corresponding communications path. The outputted video and alarm signals are provided to a video protection switch (VPS) device which provides the video signal from the second transmission path if the alarm signals indicates an error or disruption in the first transmission path. In one embodiment, the VPS has multiple switches, one for each of plural video sources, and a redundant switch and protection ports. The redundant switch and protection ports may be connected to receive the video and alarm signals if one of the switches in the VPS fails.

Abstract: A gel includes a multi-component scented mixture in which the components act in concert to create a perceived scent, disposed in a polymer matrix comprising the polymerization product of one or more ethylenically unsaturated monomers. The monomers are selected such that the gel (a) has sufficient mechanical integrity to retain its shape under ambient conditions and (b) releases the components of the scented mixture in a manner that substantially preserves the native scent of the mixture upon release.

Abstract: Label-like, hermetically-sealed perfume pouch samplers with artwork on their top surface and a pressure sensitive adhesive bottom surface. The adhesive bottom surface may be employed to attach the pouch labels to pages of a magazine or other mailer, providing an efficient method of mass distribution of perfume samples. The fragrance is stored in a perfume-releasing article such as an ultraviolet radiation-cured perfume-doped polymer, or a fragrance-laden polymer gel of modified cellulosic, ethyl alcohol, fragrance oil, an antioxidant, and water, surrounded by two perfume impervious sealed barrier layers. There is disclosed a method of manufacturing the perfume pouch labels on a support web that can be wound onto rolls from which the pouch labels may be readily released and applied rapidly and precisely to advertising pages.
