Title: Viscosity control for molten plastics prior to molding
Inventor: IBAR JEAN-PIERRE
IPC: B29C45/46
Filed: 1997-12-12
Granted: 2006-10-17
Abstract: Controlling viscosity of molten polymers, such as polycarbonate, prior to a molding operation such as injection molding, extrusion, thermoforming or blow molding, involves a reduction of viscosity in the plastic melt at constant temperature, by the action of a vigorous mechanical extensional shear vibration, with minimum or no external pressure , at a constant amplitude and frequency, causing the melt to become highly elastic and simultaneously fatigued for a certain time at that temperature, maintaining this high elastic state until the macromolecules have partially or totally disentangled, in a controllable manner, at which stage the melt is ready for a molding operation such as a simple quenching operation or an extrusion process followed by quenching to produce pellets or compounds with a better mix or a lower viscosity when remelted, or an injection molding operation where the melt viscosity has been greatly reduced allowing a better processability of the injected part.

Patent CA-2310305-C (CA)

IPC: H04B10/17
Filed: 2000-05-30
Granted: 2004-04-06
Abstract: Distortion and crosstalk that occurs when operating optical amplifiers in saturation is substantially reduced by passively compensating for gain variations caused by changes in input power to the optical amplifiers. More specifically, in an optical communication system having one or more optical amplifiers, a "reservoir" optical channel is supplied in addition to the other traffic-carrying optical channels. The wavelength of the reservoir channel is selected such that the power level of the reservoir channel varies in response to changes in power levels of the traffic-carrying channels. Because gain variations are typically highest around the gain peak region in an optical amplifier's gain bandwidth, the reservoir channel in one exemplary embodiment is assigned a wavelength around the gain peak region. As such, the reservoir channel can absorb or otherwise receive most of the distortion and crosstalk while the traffic-carrying channels located away from the gain peak region will experience less distortion and crosstalk.  Importantly, this passive compensation scheme can be used in an amplified system which is operating in the presence of nonlinear distortions caused by gain variations, such as inter-modal distortion and saturation induced crosstalk.

Abstract: Le système de l'invention permet de réaliser un mappage à dimensions réduites de données de configuration. Ce mappage est appliqué par le biais d'un réseau neuronal classique à couche simple cachée sans rétroaction muni de neurones non linéaires. Dans un aspect de l'invention, le système est mis en oeuvre pour égaliser et orthogonaliser des signaux de sortie dimensionnels plus faibles par réduction de la matrice de covariance des signaux de sortie relativement à la forme d'une matrice diagonale ou d'une constante multipliée par la matrice unité. Le procédé de l'invention permet de visualiser de grands ensembles de données multidimensionnelles complexes par une approximation des faibles dimensions relativement "topologiquement exacte", en vue de limiter la stochasticité associée à d'autres procédés poursuivant des objectifs similaires et de préserver en même temps l'efficacité computationnelle du mappage.

Title: Method and apparatus for detection and correction of illumination flicker
Inventor: SUBE MAKOTO
IPC: H04N5/235
Filed: 2000-10-06
Granted: 2004-02-03
Abstract: A video signal including illumination flicker component is integrated at each of unit areas (horizontal lines) in a frame (field) of the video signal. The integrated level at each of the unit areas at the frame and the integrated level at the corresponding unit area of an adjacent frame are averaged. Dividing is effected between results of the averaging and integrating every unit area. It is judged whether flicker exists in the video signal by frequency-analyzing results of the dividing result at the unit areas. The unit area may be plural adjacent lines where flickering are negligible. The averaging circuit may be circulation type of or FIR filter. Threshold level for judging the flicker is changed according to a shutter speed control signal. Flicker compensation may be executed by controlling shutter speed or the AGC according to flicker judging result. A still condition at a block in a frame may be detected from the integration result at plural frames. When the block is judged to be still, the flicker is judged. An ac line frequency detection is also disclosed to detect the frequency of the ac line from a video signal generated under illumination including flicker. An imaging circuit may be provided to generate the video signal therein.

Title: Vent closure member with lift spacer
Inventor: SELLS GARY L
IPC: E04D13/17
Filed: 2001-12-27
Granted: 2008-08-05
Abstract: A ridge vent assembly extends along a roof ridge of a building. One embodiment has corrugated plies defining small diameter passages that communicate a vent opening cut along the ridge of the roof with ambient atmosphere. A moveable valve member extends along the outer edge of the vent parts and includes a lift spacer to keep the valve member spaced from the roof when in an inactive position. When wind speed increases above a predetermined wind speed, the movable member moves into a position adjoining the edge of the vent parts and the bubble is compressed against the upper edge of the corresponding vent part, thereby preventing entry of wind driven moisture and snow into the passages and into the building structure through the vent opening. Accordingly, the moveable valve member acts as a weatherstripping material for the vent. A similar flexible member is usable to weatherstrip windows, doors, and other building openings.
