Abstract: L'invention concerne un procédé permettant d'identifier des pixels d'une couleur donnée dans un champ vidéo YUV, lequel procédé consiste à gérer des signaux (R-Y, B-Y) de différence de couleurs correspondant aux axes (U,V) de définition d'un espace de couleur dans le but de maximiser le signal vidéo dans une zone d'intérêt de cet espace, et de minimiser le signal dans toutes les autres zones. En outre, le signal de différence de couleurs correspondant à un axe peut tourner en direction de l'autre axe, ou la totalité de l'espace de couleur peut tourner de façon à amener la zone d'intérêt sur les axes ou à proximité de ceux-ci. Les gains et les rotations de signaux peuvent être effectués dans des circuits (52) de traitement des signaux d'une caméra couleur (50) classique, ce qui permet de n'utiliser qu'un seul comparateur (90) pour détecter la couleur cible. Après rotation et application du gain, on compare le signal de différence de couleurs définissant la zone d'intérêt à une valeur seuil afin de déterminer si un pixel est de la couleur cible. Il est possible de monter une caméra vidéo sur un pulvérisateur agricole de manière à détecter les mauvaises herbes de couleur verte sur le sol brun, par identification des pixels verts dans l'image prise au cours du déplacement du pulvérisateur dans le champ. Une fois les mauvaises herbes détectées, une substance à pulvériser peut être appliquée sur les mauvaises herbes

Abstract: A continuously variable screening tool is used to generate a unique texture pattern for every color in a multicolor image. The continuously variable screening tool allows a single colorant version of the image to be generated with less information loss than typically suffered in the multicolor to single color transformation process. The continuously variable screening, tool is generated by blending patterns from a set of reference screens. The reference screens are associated with selected reference colors in, for example, a machine independent color space. A calculated screen is generated through a weighted blend of reference screens located near the arbitrary color in the machine independent color space. Typically, the weights depend on the distance the arbitrary color is from each of the reference colors. The screens consist of arrays of threshold values. Each threshold value is associated with a dot position and an image pixel. Where a pixel value exceeds the associated threshold value, provision is made to place a mark in the associated dot position. An image processor operative to carry out the method comprises a continuously variable screening tool generator. An embodiment of the image processor includes a reference screen storage device and a screen blender.

Title: Digital exciter/phasor/transmitter for directional antenna system
Inventor: HIEB MARIO
IPC: H04B1/04
Filed: 2001-01-08
Granted: 2007-03-27
Abstract: A transmission system delays a carrier wave (20) and program audio (22) in t he digital domain. The carrier wave and the program audio are converted to anal og and the carrier wave is modulated by the program audio. The system includes a master oscillator (308) that generates a digital carrier wave. The digital carrier wave is transmitted to a delay stage (310) that delays the digital carrier wave by a certain delay value. The system further receives an analog or digital signal that is representative of programming. If an analog signal is received, the signal is transmitted to an analog-to-digital converter (30 2) where it is converted to digital audio. The digital audio is then transmitte d to a delay stage (316) that delays the digital audio by the same delay value . The digital carrier wave and the digital audio are converted to an analog carrier wave and analog audio respectively. A modulator (322) modulates the analog carrier wave by the analog audio and sends the amplitude modulated carrier wave to a power amplifier (324). After power amplification, amplitud e modulated carrier wave is broadcast by a conventional antenna (330). The del ay of the carrier wave and the program audio are controlled by a processor (332 ). The processor may also control the output power of respective power amplifie rs (324).

Abstract: A metal gasket (10) for use in sealing between a cylinder head (12) and a block (14) of an engine (16) includes at least one layer (37) formed with at least one opening therethrough and a deformation feature in the form of a sealing bead (34), stopper (40), or both surrounding the opening. The gasket layer is fabricated of austemper-hardenable steel formed when in an annealed state and thereafter austempered to harden the layer and relieve residual forming stresses. During austempering, the layer is supported in a porous fixture that retains the layer against movement out of its plane while permitting it to move within its plane. The fixture has coarse expanded metal exoskeleton liner with wire mesh panels. The mesh liners maintain molten salt against the layers which acts as a thermal cushion to discourage warpage.

Abstract: The invention relates to improvements made to membrane filtration, especially micro-, ultra-, nano- or hyperfiltration of effluents containing suspended matter, especially water. The aim of said improvements is to reduce the fouling of the membranes and to improve the filtration capacity. The improvements are characterized in that they consist of adding a dose of a coagulation reagent to the effluent before it passes over the membrane, this reagent destabilizing the colloidal matters in suspension. The dose is 30 to 80 times less than that which would cancel out the Zeta potential.

Title: Spa pumping method and apparatus
Inventor: TOYE REGINALD
IPC: A61H33/00
Filed: 2002-12-19
Granted: 2010-05-25
Abstract: A water pump for a spa or the like has a pump water inlet, a pump water outlet and an impeller driving water from said inlet to said outlet. The impeller provides the water axially introduced at the pump water inlet with a radial component which delivers the water to a large plenum chamber surrounding the impeller and which plenum chamber has an increasing cross sectional area as the water moves from the pump water inlet to a plenum chamber outlet thereby reducing backpressure in the water. The plenum chamber terminates with the plenum water outlet located closely to the impeller and a smooth transition area defines the area extending from the plenum chamber outlet to the pump water outlet. The water outlet preferably extends so that the water has a directional component which is generally parallel to the direction of the water entering the pump through the pump water inlet.

Abstract: A method for determining component flow rates of a multiphase fluid in a conduit (the fluid consisting of at least three known components) includes the steps of: measuring at each of two different positions along the conduit at least four mixture quantities, typically the sound speed, the flow velocity of the multiphase fluid, the pressure and the temperature; providing a speed of sound in each of the components at the measured pressures and temperatures;  providing a trial value for each of either the component flow rates or the phase fractions; using a predetermined model to calculate values for the measured mixture quantities based on the trial values for each of either the component flow rates or the phase fractions; using a predetermined error function to determine an error value; and using a predetermined optimizing algorithm to determine whether the calculated values are acceptable, and, if they are not, to provide a new trial value for each of either the component flow rates or the phase fractions. In some applications, the error function is the sum of the squares of the difference between the measured and calculated values at each point.
