Abstract: A method for enhancing the photosensitivity of glasses useful in forming waveguides, where the waveguide material exhibits persistent UV photosensitivity after diffusion of hydrogen or deuterium out of the wavegui de material. An optical waveguide fiber (22), with a cladding layer (26) and a portion of the polymeric coating (28) removed, has a core (24) which has bee n loaded with hydrogen or deuterium to form a waveguide core (24) with an associated baseline refractive index. At least a portion of the exposed fibe r waveguide is exposed to UV radiation (32) to induce a change in the refracti ve index and then annealed to diffuse the hydrogen or deuterium gas out and stabilize the refractive index change. The resulting waveguide fiber retains  sufficient UV sensitivity to allow further changes in the refractive index, such as grating formation. This process is useful in fabricating grating devices, modifying or tuning gratings for optimum strength or wavelength charachteristics and providing accurate spatial control of waveguide sensitivity.

Title: Method and system for controlling lighting
Inventor: PYLE HARRY S
IPC: G06F9/44
Filed: 2000-02-03
Abstract: A method and system for controlling environmental conditions, such as lighting. The lighting system provides an architecture that includes a scene description data structure. A scene defines one or more circuits and a target state for the lights on those circuits. The scene description data structure specifies circuits within a scene and specifies a target state for the lights on those circuits within a scene. The lighting system provides a lighting gateway that retrieves and provides scene descriptions to assist in generating a user interface for enabling scenes, and that receives requests to enable scenes and then requests a lighting controller to enable the target state for each circuit within the scene. Each space (e.g., area or room) within the environment has a lighting component that provides a standard programmatic interface to control the lights from a space. The lighting component retrieves scene descriptions from the lighting gateway and receives requests from a user control point device to enable a scene and then forwards the requests to the lighting gateway.
