Abstract: La présente invention concerne un système AMRT (11) qui utilise une structure de trame à période fixe, programmable pour établir une communication entre des terminaux (6, 10) de réseau. Toutes les rafales de données sont temporisées par rapport à cette trame périodique programmable. Chaque terminal (6, 10) utilise son horloge locale pour produire une période de trame d'émission et une période de trame de réception. Selon l'invention, une procédure d'acquisition et de synchronisation est fournie de façon à aligner le début de la période de trame d'émission et le début de la période de trame de réception au niveau de chaque terminal de sorte que si une rafale est émise par un terminal quelconque, avec un décalage x après un début local d'une période de trame d'émission, tous les terminaux reçoivent cette rafale à une position y après le début local des périodes de trame de réception, |y-x| étant inférieur à une faible valeur de seuil. En outre, on utilise un nombre de types différents de rafales pour établir une communication entre des terminaux. Ces différents types de rafales sont programmables. En d'autres termes, les paramètres qui définissent les rafales, tels que la longueur, la fréquence et l'implantation dans une trame peuvent être affectés dynamiquement par le réseau sur la base de conditions de réseau contrôlées.

Granted: 2002-07-02
Abstract: A method and an apparatus for power generation, by which high-efficiency power generation is achieved by utilizing a boiler-oriented fuel such as inexpensive coal, heavy oil and waste plastic, and by further utilizing a gas- turbine-oriented fuel in some cases, without exerting bad effects on the environment, at low equipment cost. In the apparatus, first, the boiler-oriented fuel is separated into a distillate and a residue by partial processing. The distillate (in some cases, with a gas-turbine-oriented fuel) is supplied to a gas turbine to generate electric power.  Further, a combustion exhaust gas discharged from the turbine is supplied to a boiler. Then, the residue (in some cases, with a boiler-oriented fuel) is burned to obtain steam.  Further, electric power is generated by the steam.

Abstract: A color translating UV microscope for research and clinical applications involving imaging of living or dynamic samples in real time and providing several novel techniques for image creation, optical sectioning, dynamic motion tracking and contrast enhancement comprises a light source emitting U V light, and visible and IR light if desired. This light is directed to the condenser via a means of selecting monochromatic, bandpass, shortpass, longpass or notch limited light. The condenser can be a brightfield, darkfield, phase contrast or DIC. The slide is mounted in a stage capable of high speed movements in the X, Y and Z dimensions. The microscope uses broadband, narrowband or monochromat optimized objectives to direct the imag e of the sample to an image intensifier or UV sensitive video system. When an image intensifier is used it is either followed by a video camera, or in the simple version, by a synchronized set of filters which translate the image t o a color image and deliver it to an eyepiece for viewing by the microscopist. Between the objective and the image intensifier there can be a selection of static or dynamic switchable filters. The video camera, if used, produces an image which is digitized by an image capture board in a computer. The image is then reassembled by an overlay process called color translation and the computer uses a combination of feedback from the information in the image an d operator control to perform various tasks such as optical sectioning and thr ee dimensional reconstruction, coordination of the monochromator while collecti ng multiple images sets called image planes, tracking dynamic sample elements i n three space, control of the environment of the slide including electric, magnetic, acoustic, temperature, pressure and light levels, color filters an d optics, control for microscope mode switching between transmitted, reflected , fluorescent, Raman, scanning, confocal, area limited, autofluorescent, acous to- optical and other modes.

Abstract: The invention relates to a system and method for indicating when changes to values of data fields in a document have occurred. In one embodiment of the invention, two objects are created upon the loading of an HTML form on an HTML page in a web browser. One object stores the initial values of the data in the HTML form, while the other object is subsequently updated so that the current values of the data in the HTML form are stored therein. When the data in the HTML form is submitted to a server, the data in the two objects are compared to determine which data fields of the HTML form are "dirty"; i.e., which data fields have current values different from their initial values. A  record identifying which data fields are "dirty" is created and is submitted to the server along with the data in the HTML page.
