Abstract: A biodegradable delivery particle having a benefit agent containing core and a shell.

Abstract: Populations of benefit agent delivery particles are disclosed, the particles having a core and a polymer wall surrounding the core, the polymer wall comprising multifunctional (meth)acrylate-based polymers, along with processes for making and uses of such compositions, and articles made with such particles. The polymer wall comprises a (meth)acrylate polymer derived, at least in part, from wall monomers and at least one free radical initiator, wherein the wall monomers comprise at least 50%, by weight of the wall monomers, of (meth)acrylate monomers, wherein the at least one free radical initiator is present at a level of from about 15% to about 60%, by weight of the polymer wall, wherein the core comprises a benefit agent, wherein the core and the polymer wall are present in a weight ratio of from about 95:5 to about 99.5:0.5. The compositions deliver core content with a desired delivery profile.

Abstract: The present invention provides a method, apparatus and system for a protocol and line-rate transparent WDM passive optical network architecture that scales in terms of bandwidth and number of ONUs. Both an included optical line terminal and each of a plurality of ONUs use substantially the same reflective modulators to modulate respective wavelength channels to impart data thereto. In various embodiments of the present invention, the reflective modulators are composed of a SOA having on one facet a pigtailed fiber and the other facet coated with a highly reflective coating. In the WDM passive optical network of the present invention, the ONUs each comprises a separate wavelength for communication in the upstream and the downstream directions. The present invention allows for all-passive components to be placed in the field, thus, requiring no power between a central office and a user or subscriber's premises.
