IPC: H04Q11/04
Filed: 1999-02-24
Abstract: A method and a system for controlling a dynamic channel reconfiguration of an access facility in which a first bit stream is connected on a first channel to a second channel. A status associated with the first bit stream is queried. In response to the query, status information, which includes a configuration map status, is received for the first bit stream. The configuration map status for the first bit stream is then stored in a first memory area. A command is received for disconnecting the first bit stream on the first channel from the second channel, and the first channel is disconnected from the second channel. A set of parameters associated with the first channel are then groomed to match a set of parameters associated with the third channel. A command is received for connecting a second bit stream on the first channel to a third channel. A  configuration status for the second bit stream is stored in a second memory area. The first channel is then connected to the third channel, and the second bit stream on the first channel is directed to the third channel. The dynamic channel reconfiguration implementation is restored by disconnecting the first channel from the third channel, regrooming the parameters associated with the first channel, storing retrieved configuration map status for the first bit stream in the second memory area, connecting the first channel to the second channel, and directing the first bit stream on the first channel to the second channel.

Title: Fan with centrifugal shutter mechanism
Inventor: MILANA ANGELO
IPC: F04D25/14
Filed: 1999-04-26
Abstract: A fan for moving air into or out of a building comprises a novel centrifugal mechanism for operating an associated shutter made of a plurality of pivoted vanes and a central vane interconnected by two heavy tie rods, a wall-housing defining a quasi square air flow passage having large radii at each corner, an electric reversible motor and an impeller which are fastened to a central structural member. The centrifugal mechanism is made up of a smaller number of parts and joints required to prevent looseness and vibrations even after long term use and it is connected for rotation to the fan impeller comprising a closed housing wherein are located, symmetrical spaced apart in rapport to the fan axis, at least a pair of radial masses operatively connected via flexible means to an axial hollow operative actuator which is located adjacent to the shutter central vane. When the fan starts to rotate in either direction, each radial mass slides radially outwardly from the axis of rotation of the fan pulling the axial actuator inside the housing allowing the shutter heavy tie rods, by gravity, to open the shutter. When the fan stops, a spring associated with the axial hollow operative actuator pushes it outwardly of the closed housing against the central vane of the shutter causing the closing of the shutter.

Abstract: A self-cleaning appliance, e.g., an oven, is provided herein. Such appliance comprises one having at least one surface over which organic contaminants are expected to accumulate and a photocatalytically-activated, self-cleaning coating of photocatalytically-activated, self-cleaning oxides which are essentially free of a binder, such oxides are formed on the at least one surface from sol-gel giving a photocatalytically-activated, self-cleaning coating from photocatalytically-activated oxides with a thickness within the range of about 200 to 5000 Angstroms, or from spray pyrolysis, chemical vapour deposition, or magnetron sputtering vacuum deposition over said surface. Then, the appliance is rendered self-cleaning of accumulated organic contaminants on one or more surfaces of the appliance, by coating such surfaces of the appliance with a photocatalytically-activated self-cleaning coating. Upon exposing such coated surfaces to radiation of the appropriate wavelength, for a sufficient interval of time, at least a portion of the organic contaminants present on the photocatalytically-activated self-cleaning coating are removed. The coated surface is thereby cleaned without the need of manual effort or high temperatures. The radiation is generally actinic radiation, and more particularly includes ultraviolet radiation.

Abstract: Methods and computer executable instructions are provided for converting original images such as photographic pictures into various other formats such as drawings by reducing the amount of data contained in the original images. It is a feature of this invention that a photographic picture can be converted into a drawing useful as a template to enable a person to paint the template into a likeness of the photographic picture. In a preferred embodiment, an original image is supplied to a computing environment where it is quantized into pixels of information. Each scalar value of each pixel is evaluated and aberrant pixels are absorbed into adjacent pixels by converting various scalar values.  Thereafter, pixels having similar scalar values are grouped into regions. The boundaries between the regions are absorbed into each of the surrounding regions to provide a smoothed boundary. The regions then provide a template conducive to painting.

Abstract: Selon cette invention, des dérivés de benzopyrane, benzothiopyrane aryl-substitué et aryl et (3-oxo-1-propényl)-substitué, de 1,2-dihydroquinoléine, et de 5,6-dihydronaphtalène présentent des activités biologiques du type hormone négative rétinoïde et/ou antagoniste. Les antagonistes des récepteurs d'acide rétinoïque (RAR) peuvent être administrés à des mammifères, y compris à des êtres humains, aux fins d'empêcher ou diminuer l'action des antagonistes des RAR sur les sites récepteurs fixés. En particulier, les antagonistes des RAR peuvent être administrés, ou coadministrés, avec des médicaments rétinoïdes dans le but d'empêcher ou réduire la toxicité ou les effets secondaires provoqués par les rétinoïdes ou la vitamine A ou des précurseurs de la vitamine A. Les hormones négatives rétinoïdes peuvent être utilisées pour potentialiser les activités d'autres rétinoïdes et agonistes des récepteurs nucléaires. Par exemple, l'hormone négative rétinoïde AGN 193109 a augmenté de manière certaine l'efficacité d'autres rétinoïdes et d'hormones stéroïdes dans des dosages de trans-activation in vitro. En outre, ces dosages peuvent être utilisés pour identifier des composés présentant une activité d'hormone négative. Ces dosages sont basés sur l'aptitude d'hormones négatives à réguler de manière négative l'activité de récepteurs rétinoïdes chimères manipulés afin qu'ils comportent un domaine constitutif activateur de transcription.
