Title: Method and apparatus for reducing the unwanted effects of noise present in a three dimensional color imaging system
Inventor: RIOUX MARC
IPC: G06T1/00
Filed: 1997-02-12
Granted: 2002-07-09
Abstract: A method and apparatus is provided that lessens the unwanted effects of noise present at the input of an imaging system. By tapping a small portion of a laser input signal containing wavelengths of light corresponding to red, blue, and green of light used to scan the surface to be imaged, the tapped signal is used to generate three beams that correspond to the red, blue, and green content of the laser input signal. Signals generated at the output of the system that correspond to the color of the scanned surface are normalized with the signals that correspond to the three beams generated by the tapped signal. The normalized output signal indicative of the color of the surface is noise reduced; substantially most of any noise present at the input is eliminated from the output of the device.

Abstract: A microwave/millimeter wave circuit structure supports discrete circuit elements (2) by flip-chip mounting to an interconnection network (10) on a low cost non-ceramic and non-semiconductor dielectric substrate (2), preferably Duroid. The necessary precise alignment of the circuit elements with contact pads (14) on the substrate network required for the high operating frequencies is facilitated by oxidizing (20) the interconnection network, but providing the contact pads from a non-oxidizable material (14') to establish a preferential solder bump (8) wetting for the pads. Alternately, the contact bumps on the flip-chips can be precisely positioned through corresponding openings (28) in a passivation layer (26) over the interconnection network.  For thin circuit substrates that are too soft for successful flip-chip mounting, stiffening substrates (24) are laminated to the circuit substrates.  In a self-contained antenna application in which two of the circuit substrates (32, 36) are laminated together, with an antenna (34) on one side and circuitry on the other side, a metallic ground plane (56) between the substrates also serves a stiffening function.

Title: Cell selection scheme in cdma mobile communication system using spread codes and spread code phases
Inventor: NAKAMURA TAKEHIRO
IPC: H04W48/12
Filed: 1997-03-04
Granted: 2000-08-22
Abstract: A cell selection scheme in a CDMA mobile communication system which is capable of shortening the cell selection processing time while constructing a mobile communication system with a practically feasible base station configuration. In a CDMA mobile communication system, first type base stations which share a common reference timing are transmitting pilot channels spread by using an identical pilot channel spread code at mutually different spread code phases with respect to the common reference timing where these mutually different spread code phases are assigned to different first type base stations, and second type base stations which do not share the common reference timing are transmitting pilot channels spread by using mutually different pilot channel spread codes at arbitrary spread code phases where these mutually different pilot channel spread codes being assigned to different second type base stations. A mobile station receives these pilot channels and judges a located cell of the mobile station according to receiving levels, pilot channel spread codes and spread code phases of received pilot channels.

Abstract: A coupling arrangement includes an inverted u-shaped frame having opposite legs joined by a transverse bight portion. The lower draft links of a tractor three-point hitch are connected to lower ends of the legs of the frame for pivoting about a horizontal transverse axis. Located centrally between the frame legs along the bight portion of the frame is an angle member having a horizontal limb defining a first link and being joined to a vertical limb defined in part by an upwardly projecting bearing axle. An implement draft tongue includes a forward extension to which upwardly and downwardly projecting bearing axles are fixed along a vertical axis. The coupling arrangement includes a second link spaced vertically above the first link and having ball joints in its opposite ends respectively mounted to the bearing axle of the angle member and the upwardly projecting bearing axle of the draft tongue. A ball joint is mounted in the first link and is received on the downwardly projecting bearing axle of the draft tongue. Accordingly, the first and second links and the ball joints they carry act to transfer tensile and compressive loads between, and permit universal movement between, the implement and the tractor.

Abstract: L'invention concerne une vanne déversoir de régulation d'écoulement et son procédé de fonctionnnement. La vanne possède une entrée (12), une sortie (14), une entrée de dérivation (16), un couvercle pivotant (20) et un mécanisme de commande du couvercle afin de créer un écoulement de déversement à travers la vanne. Le couvercle est forcé en continu vers une première position fermée au moyen d'un ou de plusieurs ressorts (21) ou autres mécanismes élastiques produisant une force. Lorsque le fluide s'écoule dans la vanne, la force de fermeture générée par les ressorts peut être vaincue par la basse pression générée à l'intérieur de la vanne, ce qui permet à l'environnement ambiant de forcer le couvercle à s'ouvrir au moins partiellement dès que le débit de fluide dépasse une valeur seuil. Un gradin (40) ménagé dans le corps de la vanne peut être utilisé pour interrompre l'écoulement de fluide et créer un effet Venturi afin de faciliter encore plus l'ouverture du couvercle. Le couvercle est suffisament sensible pour permettre un écoulement de déversement à travers l'entrée de dérivation et compenser les variations de pression rapides et importantes qui se créent à l'intérieur d'un système de nettoyage auquel la vanne peut être rattachée. De plus, la vanne peut être placée de sorte que le fluide admis à travers l'entrée de dérivation crée un effet d'écumage qui aspire des débris se trouvant à la surface du liquide dans lequel la vanne peut être montée dans le système de nettoyage, à travers l'entrée de dérivation.

Abstract: Procédé et dispositif de génération de signaux de télécommunications à codage orthogonal conçus pour des abonnés d'un système de télécommunications au moyen de fonctions orthogonales multiples pour chaque canal de communication orthogonale. Des symboles de données numériques pour les récepteurs des signaux sont modulés en fonction d'un niveau de modulation M-aire utilisant au moins deux symboles de modulation orthogonale de longueur n, qui sont généralement des fonctions de Walsh qu'on utilise normalement à l'intérieur du système de télécommunications. Ces symboles sont produits par un sélecteur de symboles de modulation (124) à partir d'un ou plusieurs générateurs de code (126, 128) et la modulation est telle que M est égal à un produit du nombre total de fonctions orthogonales et du nombre utilisé pour générer des symboles individuels de modulation. Chaque groupe de symboles de données à codage logarithmique M provenant d'éléments de traitement de données (100, 102) est configuré en un seul symbole de modulation au moyen de l'élément de sélection de symbole de modulation (124) en fonction des valeurs binaires des symbole dudit groupe. Dans certains modes de réalisation, on utilise un transformateur rapide de Hadamard afin d'établir la topographie des symboles. Les signaux de télécommunications obtenus sont démodulés par mise en corrélation avec le nombre présélectionné de fonctions orthogonales, en parallèle, ainsi que par démodulation des résultats en valeurs d'énergie M représentant chacune un symbole de modulation orthogonale. Les valeurs d'énergie sont configurées en données métriques d'énergie au moyen d'un double processus de génération métrique maximum. La corrélation et la démodulation peut s'effectuer au moyen de deux ensembles au moins de corrélateurs N (142), N représentant le nombre de fonctions utilisées, ainsi qu'au moyen de l'application de signaux mis en corrélation à un démodulateur pour chaque ensemble de corrélateurs (144). Chaque démodulateur produit des valeurs d'énergie M représentant chacun des symboles de modulation réciproquement orthogonale M, qu'on réunit ensuite en une combinaison unique de valeurs d'énergie M. Dans d'autres configurations, des démodulateurs cohérents (172, 174) peuvent s'utiliser afin de produire des valeurs d'intensité pour les signaux reçus, qui sont ensuite combinées (178) avec des résultats métriques doubles maximum (170) afin d'obtenir des valeurs métriques composites des symboles de données (178).

Abstract: An exhaust manifold for an engine includes a manifold body 7 having a plurality of branch pipes and a common collecting chamber  integrally  connected  to  the  branch  pipes  and communicating with an exhaust emission control device is divided into an upper half and a lower half at a boundary face extending in a direction of arrangement of the branch pipes.          The upper and lower halves are made of steel plates and welded to each other.  In the exhaust manifold, a welding mating coupler is formed by outer edges of the upper and lower halves, and a welding stepped superposing coupler is formed by inner edges of the upper and lower halves.  Thus, during welding, it is possible to limit the misalignment of the upper and lower halves  in a direction along the boundary face  and the misalignment of the upper and lower halves in a direction perpendicular to the boundary face by cooperation of the mating coupler and the stepped superposing coupler.  In addition, because the stepped superposing coupler is used for coupling of inner edges of the upper and lower halves to each other, it is possible to ensure sufficient clearances between the adjacent branch pipes, and to easily conduct the operation of mounting of the exhaust manifold to the engine by utilizing the clearances.

Abstract: In an ultrasonic apparatus a plurality of piezoelectric electroacoustic transducers (10, 12) are mechanically coupled to a horn (14) for providing ultrasonic vibrations thereto, and the transducers are energized in parallel from a common electrical power supply (28).  In order to avoid the presence of circulating currents among the transducers, transformer balancing units (30) are connected in circuit with each of the transducers.  Since the use of parallel connected piezoelectric transducers increases the total circuit capacitance, series connected capacitors (32, 34) are provided to restore the circuit capacitance to a value required for the resonant circuit condition.

Abstract: An elastomeric compressor mount has a hollow convex cylindrical head portion which is passed upwardly through a corresponding opening in a support foot portion of the compressor to place an annular portion of the foot in an annular mount groove which is disposed between its head portion and a larger cylindrical base portion of the mount. When  a  securement  bolt  is  passed  axially  through  a fastening opening  in the  mount  and tightened  into  an underlying base pan opening, the convex mount head portion is downwardly and radially outwardly deformed to cause the annular foot portion to be resiliently squeezed between the head portion and the underlying base portion of the mount. In a second embodiment of the mount its convex cylindrical head portion is of a solid configuration, and is joined to the  mount  base  portion  by  an  annular  flange  section coaxially disposed therein.  When the securement bolt is tightened the head portion is pushed downwardly relative to the mount body portion in a manner axially flexing the flange section and squeezing the annular compressor foot portion between the head and base sections of the mount. In a third embodiment of the mount its head section is cylindrical and has a depending,  reduced diameter stem section which is telescoped within the underlying mount base section to permit relative axial movement between the head and base sections of the mount when the securement bolt is tightened.

Title: Method for determining the average radiation of a burning bed in combustion installations and for controlling the combustion process

Granted: 1999-11-30
Abstract: For determining the average radiation of a surface region of a burning bed,  an infrared camera  (22) is  used  in  a  firing  installation,  which  camera  is aligned with this region and is equipped by means of appropriate flame  filters  in  such  a  way  that  it operates at the minimum of the interfering radiation emanating   from   the   flame   (24a),   whereby   this interfering radiation is already largely eliminated. In order then also to eliminate the solids radiation from moving  particles  and  thus  to  obtain  a  temperature measurement  of  the  burning bed  (24),  recordings  are made successively at short intervals of time by means of the infrared camera (22) and these are evaluated in the evaluation and control device (23). For calculating an average value of the radiation or of the average temperature,  only those part  surfaces  of the surface region subdivided into a plurality of part surfaces are here taken into account which are not subject to any change and can thus be allocated to the burning bed which is to be regarded as being essentially at rest, while  the  varying  radiation  results  from other  part surfaces are to be ascribed to the solids radiation of moving particles, such as, for example, dust particles and soot particles,  which falsify the temperature of the burning bed.
