Abstract: Provided are assemblies and processes for achieving desirable homogenization and mixing of one or more light sources. The assemblies include the use of diffusers and light pipes in a particular configuration that allows very good homogenization performance while reducing the requisite length of light pipe. In particular, a length of a light-pipe homogenizer can be substantially reduced by diffusing the light after it has been partially pre-mixed by a light pipe. Additional mixing can take place after diffusion. For example, a diffuser can be positioned within a light pipe or sandwiched between two light pipes. In some embodiments, the diffuser is placed at a point along a light pipe where the light from each source or each portion of a single source substantially covers the diffuser approximately equally. Consequently, a rate of homogenization can be increased, thereby reducing the required length of the complete homogenization system.

Abstract: A policy-driven communication and management infrastructure may include components such as Agent, Server and Console, policy messages, and Relays to deliver security and system management to networked devices. An Agent resides on a Client, acting as a universal policy engine for delivering multiple management services. Relays, Clients additionally configured to each behave as though they were a root Server, Relaying information to and from other Clients, permit Clients to interact with the root Server through the Relay, enabling information exchange between Client and Server. Such information exchange allows Clients to gather information, such as new policy messages, from the Server, to pass status messages to the Server and to register their network address so that they can be readily located. Automatic Relay selection enables Clients and Relays to select their own parent Relays, thus allowing Clients and Relays to discover new routing paths through the network without administrator input.
