Title: A digital controller for a cooling and heating plant having near-optimal global set point control strategy
Inventor: CASCIA MARK A
IPC: F28F27/00
Filed: 1998-04-27
Abstract: A DDC controller is disclosed which implements a control strategy that provides for near-optimal global set points, so that power consumption and therefore energy costs for operating a heating and/or cooling plant can be minimized. The controller can implement two chiller plant component models expressing chiller, chilled water pump, and air handler fan power as a function of chilled water supply/return differential temperature. The models are derived from a mathematical analysis using relations from fluid mechanics and heat transfer under the assumption of a steady-state load condition. The analysis applies to both constant speed and variable speed chillers, chilled water pumps, and air handler fans. Similar models are presented for a heating plant consisting of a hot water boiler, hot water pump, and air handler fan which relates power as a function of the hot water supply/return differential temperature. A relatively simple technique is presented to calculate near-optimal chilled water and hot water set point temperatures whenever a new steady-state load occurs, in order to minimize total power consumption. From thecalculated values of near-optimal chilled water and hot water supply temperatures, a near-optimal discharge air temperature from a central air handler can be calculated for each step in load. Although the set points are near-optimal, the technique of calculation is simple enough to implement in a DDC controller.

IPC: G02B6/136
Filed: 1996-12-02
Abstract: A method and apparatus is disclosed for creating a structure, such as a grating (45) in a photosensitive material (40). The method and apparatus relies upon creating at least two coherent beams of light (33, 38) and reflecting them, in a counter propagating manner, around a series of reflective elements (35, 37) along substantially equivalent paths so that the coherent beams interfere at a structure staging area (45). The structure staging area can then be utilised to create grating structures or the like having improved qualities.

Abstract: Système et procédé d'acquisition informatique d'événements bénéficiant d'une souplesse qui permet d'acquérir des longueurs variables et sans relation de séquences d'images vidéo avant, pendant et après un événement. Ledit système d'acquisition d'événements stocke des images vidéo enregistrées pendant la surveillance dans un nombre fixe de fichiers de telle manière qu'une fois le nombre maximal de fichiers à stocker pendant la surveillance atteint, le fichier le plus ancien est effacé et le fichier contenant les images vidéo nouvellement acquises est stocké dans un nouvel endroit de la mémoire. Par conséquent, le stockage des fichiers pendant la surveillance présente une configuration circulaire. Des images vidéo enregistrées après l'apparition d'un ou plusieurs événements sont stockées dans des fichiers de configuration linéaire. Le nombre de fichiers stockés dans la mémoire permanente parmi les fichiers enregistrés pendant la surveillance n'a aucune relation au nombre de fichiers stockés après l'événement. Outre qu'il n'a pas de relation au nombre de fichiers antérieurs à l'événement stockés en permanence, le nombre de fichiers postérieurs à l'événement stockés en permanence est également sans relation au nombre total de fichiers correspondant aux images vidéo acquises avant, pendant et après l'événement. Lesdits système et procédé d'acquisition d'événements permettent également le stockage local et éloigné et la capacité de relecture d'images vidéo à partir de lieux multiples dans un environnement.

Inventor: HAALAND PETER D
IPC: G02B1/11
Filed: 1997-12-12
Abstract: A method of coating optical substrates with anti-reflection (AR) coatings is described. The thickness and composition of the coating is determined by minimizing the product of the Fresnel reflection coefficients for a coating with the angular- and wavelength-dependent sensitivity of the human visual system to minimize the perceived reflectance for the coated article. A compact chamber is evacuated and flushed with chemically inert gas such as argon or nitrogen. One or more molecular precursors are deposited using plasma enhanced chemical vapor deposition (PECVD) to form AR films. Single-layer AR coatings based on fluoropolymer films of controlled thickness, as well as organic, organosilicon, and/or inorganic multilayers are described. Also provided is a method for monitoring film growth optically, using a polarized, light-emitting diode, a polarizing optical filter, and a photodiode. Feedback from the monitor is used to control the precursor flow to produce single layers and multilayers with prescribed anti-reflection properties.

Abstract: The invention concerns a process, a facility and a continuously operating press for the manufacture of material board. In the process of the invention, just prior to reaching the reaction starting temperature of the bonding agent in the press, for the curing of the centre of the material to be pressed, i.e, after the centre T M of the material to be pressed has reached approximately 85% to 95% of the respective temperature required for curing, the surface of the mat of material to be pressed is subjected to a cooling process. The pressing/cooling section L K of the press, is of a length sufficient for the curing of the mat of material to be pressed as well as for a predetermined, non-destructive steam pressure in the interior of the finished panel. The press is therefore designed in' such a way that the pressing section (L) is divided into a pressing/heating section (L H) and a pressing/cooling section (L K), whereby the pressing/cooling section (L K) is variably extendable from the pressing/heating section (L H) by means of variable pressure plate cassettes (15) which can be cooled and are located within a variable section (M), as well as vice versa, so that the pressing/heating section (L H) is variably extendable from the pressing/cooling section (L K).
