Abstract: A first light source system comprises a light guide with light deflecting particles. If its light emission function and concentration variation function (of the light deflecting particles) are known, then a similar second light source system with a desired light emission function can be designed using the following method. The concentration variation function of the second light source system is obtained by mutating the concentration variation function of the first light source system using the same mutating function that mutates the light emission function of the first light source system into the light emission function of the second light source system.

Abstract: A new approach towards transmitting media across a network is disclosed. In an embodiment, the sender prioritizes the data to be sent from a pool of candidate data, and sends it under some bandwidth constraint. The pool of candidate data reflects the present state of the media, and certain data may be discarded without being sent if it becomes irrelevant to the present state of the media. The receiver sends feedback regarding what data is received by it, which may be used for choosing candidate data, or for prioritizing it.

Abstract: A light guide system is disclosed in which one or more light sources are embedded within the body of the light guide. The light sources emit light into the light guide. Light entering the light sources from outside is either reflected back or is allowed to pass through. In an embodiment, a light guide with light deflecting particles within it is used. The concentration of the light deflecting particles within the light guide can be varied based on the location of the embedded light sources in order to obtain a desired light emanation pattern. In an embodiment, external light sources can be used to increase the amount of light and mirrors can be used to reduce wastage and increase the amount of light. Finally, by building the light guide system in a modular form, multiple light guide modules can be combined to get a light source of desired specifications.

Abstract: Linear light sources with features that enhance light extraction are disclosed. In an embodiment, a linear light guide with one or more reflective faces is oriented in such a manner that deflected light undergoes reduced reflections. In another embodiment, a linear light guide with non-parallel side faces is combined with a particularly shaped reflector. The particular features result in efficient light extraction from linear light guides.

Abstract: A light source with a light recovery mechanism is disclosed. In one embodiment, the system comprises a light source placed within a mirrored enclosure. The light source is used to illuminate a light guide. All of the light entering the light N guide might not be utilized. Some of the light might get reflected back in the direction of the light source, or may travel to the other end of the light guide. The mirrored enclosure of the light source reflects this light back into the light guide. Thus the light source placed within a mirrored enclosure acts as a light source emitting light into a light guide and also redirects light coming out of the light guide back into the light guide.
