Abstract: A system for sensing and maintaining the light level within an area. The invention comprises multiple lux sensor readers that function to measure the current light level within an area. The readings are averaged such that over time any extreme readings are averaged out. The light level of the plurality of light sources (28) is adjusted in accordance with the averaged readings. The system includes control units (26), controllers, controls for window, skylight, light pipe and shading, HVAC controls, lighting loads (28) and lig ht sensors (22), that are used to construct the lighting control system of the present invention.

Abstract: The X-ray detection element of an X-ray detector is composed of a fluorescent material having a short afterglow and a high sensitivity to the X-radiation to be detected. For the fluorescent material use is notably made of cerium-activated phosphors such as yttrium phosphors, lanthanum phosphors or lutetium phosphors.
