Title: Locating features in an image
Inventor: GRAF HANS PETER
IPC: H04N7/26
Filed: 1996-05-29
Granted: 2000-05-23
Abstract: An embodiment of the present invention locates facial features in an image by bandpass filtering the image and then performing morphological operations followed by a thresholding operation. This initial processing identifies candidate areas where facial features may be located. The candidate areas are evaluated by classifiers to determine if a facial feature, such as an eye or mouth, has been located.

Title: Procede de production d'agglomerats a partir de poussieres
Inventor: BOULANGER CLAUDE
IPC: C01F7/025
Filed: 1994-12-12
Granted: 1999-07-13
Abstract: Procédé de production d'agglomérats résistants, essentiellement dépourvus de poussières, à partir de la poussière générée par une opération industrielle. Il peut s'agir, par exemple, d'une opération effectuée sur un minerai ou un minéral, pendant la transformation thermique d'un matériau contenant essentiellement de l'alumine de qualité gibbsite à sub-alpha, selon un procédé thermique à plusieurs étapes comportant au moins une étape intermédiaire. Ce procédé consiste à broyer des particules de matériau liant contenant de l'alumine sous-calcinée jusqu'à l'obtention d'une taille de particule inférieure à 30 x 10-4 cm (30 microns) et d'une aire de surface comprise entre 90 et 300 m2/g; à combiner environ 1 à 4 parties en poids de la poussière avec une autre partie en poids du matériau liant broyé pour former des solides combinés; à mélanger les solides combinés avec de l'eau pour produire des agglomérats. L'eau est mélangée avec les solides combinés par une opération de mélange intensive dans un mélangeur pourvu d'un moteur, et est ajoutée en deux étapes, selon lesquelles: (a) 40-80 % de la quantité d'eau totale est ajoutée à des solides combinés à une vitesse telle qu'il suffit de 10 minutes au plus pour réaliser cette opération; (b) on commence à ajouter le reste de l'eau et à mesurer une caractéristique dudit mélange correspondant à sa viscosité, cette mesure servant de valeur de référence; et (c) on continue d'ajouter le reste de l'eau tout en continuant de mesurer la caractéristique du mélange, l'eau étant ajoutée à une vitesse telle que la caractéristique du mélange reste la même que la valeur de référence pendant toute la durée de l'adjonction ou varie à raison de moins de U 5 %.

Granted: 2006-08-01
Abstract: This invention is related to an active matrix liquid crystal display (AMLCD) having a high pixel aperture ratio. The display has an increased pixel aperture ratio because the pixel electrodes are formed over the insulating layer so as to overlap portions of the array address lines. Both the manufacturability and capacitive cross-talk of the TFT-based device are improved due to the use of a photo-imageable insulating layer between the pixel electrodes and the address lines. Both the manufacturability and capacitive cross-talk of the TFT-based device are improved due to the use of a photo-imageable insulating layer between the pixel electrodes and the address lines. According to certain other embodiments, the insulating layer may be BCB (either photo-imageable or not) and/or have a dielectric constant less than about 3Ø

Abstract: A two stage brake valve communicates fluid pressure to a brake mechanism. The brake valve has an inlet for receiving pressurized brake fluid from a pump, a reservoir port, a stepped bore and a stepped piston member comprising a larger diameter prefill piston and a smaller diameter high pressure piston. The stepped bore and the stepped piston form a high volume prefill chamber and a high pressure chamber. The high pressure piston has a metering groove which controls communication between the inlet and the brake mechanism. A bleed orifice is formed in the high pressure piston and communicates the high pressure chamber to an outer surface of the high pressure piston. The bleed orifice includes an annular bleed groove formed in an outer surface of the high pressure piston and a radial passage extending from the bleed groove to an interior of the high pressure piston. The bleed groove is positioned so that the bleed orifice is open to the reservoir port via the prefill chamber during initial piston movement, and closed upon movement of the high pressure piston a predetermined distance beyond the position wherein the metering groove is first communicated with the inlet.

Granted: 2001-10-09
Abstract: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.

Abstract: An aircraft engine is attached to the fuselage by a mounting structure that has a vibration absorbing system which includes first and second sensors to produce signals indicating vibration along two orthogonal axes. A third sensor, such as an accelerometer, is coupled to the mounting structure for sensing vibration of the engine. A tachometer circuit, connected to the third sensor, produces first and second speed signals that indicate the speeds of two rotating spools in the engine. Four vibration absorbers are attached to the engine mounting structure and controllers are provided to dynamically tune the resonant frequency of each vibration absorber in response to a unique combination of one of the two vibration signals and one of the two speed signals. Thus the vibration absorbers reduce the engine spool vibrations that are transmitted through the mounting structure along the two orthogonal axes. The resonant frequency of each absorber is altered to track variation of the vibrations due to changes in engine speed.
