Abstract: A method/system monitors and controls operational aspects of devices in a space, for example a living, office or other human-occupied space or storage space, in a building, such as turning lights on/off, raising/lowering blinds, maintaining or changing temperature, and other operational aspects. Sensors monitor energy usage of the devices in the space, and a controller/engine compares the monitored energy usage with reference energy usage to validate whether the devices are performing as expected. A temperate set-versus-anomaly detection technique may use temperature set point adjustments by a user (during a timeframe) to determine whether an anomaly exists that requires changes in the central plant of the building.

Abstract: A light modulation element comprising, preferably consisting of a cholesteric liquid crystalline medium sandwiched between two opposing substrates, an electrode arrangement, which is capable to allow the application of an electric field, which is substantially perpendicular to the main plane of substrate or the layer of the cholesteric liquid-crystalline medium, characterized in that one of the substrates is provided with a processed alignment layer adjacent to the cholesteric liquid crystalline medium and the other substrate is either provided with an unprocessed alignment layer adjacent to the cholesteric liquid crystalline medium or is not provided with an alignment layer. The invention is further related to a method of production of said light modulation element and to the use of said light modulation element in various types of optical and electro-optical devices, such as electro-optical displays, liquid crystal displays (LCDs), non-linear optic (NLO) devices, and optical information storage devices.
