Abstract: An automatic master slave system and approach for coordinated control of a parameter, for example, a heating, ventilation and air conditioning condition, in an area of multiple spaces controlled by room controllers. Changing a layout of a zone/area in a building such as moving, adding or removing a door, increasing or splitting size of a room through movable walls, or by permanently removing partitions, changing offices to a conference room or vice versa, may occur. A size of a room may be altered within minutes, according to customer demand. For instance, rooms may be converted into a single room by removing partitions. The controllers that were controlling temperatures of the rooms independently earlier, may convert automatically into a master-slave configuration and now work together to control a larger room. If the large room is split into multiple rooms, the controllers may automatically revert to their previous configuration.

Abstract: A method for preventing the collapse of patterned, high aspect ratio features formed in semiconductor substrates upon removal of wash solutions of the type used to clean etch residues from the spaces between the features. In the present method, the spaces are at least partially filled with a displacement solution, such as via spin coating, to substantially displace the wash solution. The displacement solution includes at least one solvent and at least one fill material which is a polyalkene carbonate (PAC) and/or a saccharide. The solvent is then volatized to deposit the fill material in substantially solid form within the spaces. The fill material may be removed by thermal degradation via heat treatment, wherein the need for removal of the fill material by plasma ashing is obviated in order to prevent or mitigate silicon loss.

Abstract: Improved flight display systems and methods that selectively deemphasize terrain are provided. The method includes receiving and processing navigation reference point data, terrain data, and aircraft status data. Next, the method (a) renders on a display system, in real-time, a viewing segment defined as at least a navigation reference point for the aircraft, the viewing segment having terrain rendered in a first level of terrain contrast; and (b) determines that the aircraft is in a terrain deemphasis scenario when an altitude is certain low altitude operations.
