Patent CA-2360061-A1 (CA)
Inventor: BIERLY SCOTT
IPC: H04B1/708
Filed: 2000-11-09
Abstract: L'invention concerne un filtre adapté parallèle numérique lequel exécute de nombreuses corrélations simultanées d'un signal reçu à spectre étalé contre divers décalages de répliques de sa séquence d'étalement. Ceci permet l'acquisition rapide (12) de la phase de code du signal reçu et ensuite le transfert vers une poursuite (14) pour un récepteur multicanaux. Une nouvelle architecture de calcul de filtres apparié est utilisée, dans laquelle des éléments arithmétiques numériques communs sont utilisés à des fins à la fois d'acquisition et de poursuite. A mesure que chaque canal est acquis de manière séquentielle par le filtre apparié parallèle, un sous-ensemble des éléments arithmétiques est alors réservé à la poursuite ultérieure de ce canal. Ce procédé est répété, avec les éléments arithmétiques disponibles restants accélérant l'acquisition du canal suivant, et ainsi de suite, jusqu'à ce que toutes les ressources soient affectées en tant que canaux de poursuite. De plus, des entrées de données et des lignes à retard multiples (10) sont présentées dans cette architecture et sont disponibles pour le traitement au niveau de chaque élément arithmétique. Ainsi, des bandes de signaux et des canaux d'utilisateurs multiples peuvent être intégrés à l'intérieur d'un cadre de récepteur commun.

Title: Regeneration and genetic transformation of acacia mangium
Inventor: HONG YAN
IPC: C12N15/82
Filed: 2000-01-19
Abstract: The present invention is directed to a method of Acacia mangium regeneration through organogenesis and a method of genetic transformation of Acacia mangium. The method of regeneration comprises inducing callus from different parts of seedlings and vegetatively micropropagated plantlets as explants;  adventitious bud induction followed by pinnate leaf and bud elongation and eventually, elongated shoots were induced to root. Based on the regeneration system, a marker gene GUS under cauliflower mosaic virus promoter was introduced to Acacia mangium via Agrobacterium infection. GUS staining in the regenerated plants and Southern blot hybridization prove the incorporation of the foreign gene into the host genome and expression of the foreign gene.

Title: Method of removing water and contaminants from crude oil containing same
Inventor: KRESNYAK STEVE
IPC: B01D1/00
Filed: 2001-12-11
Abstract: A method for contaminant and water removal from crude oil. The method involves recirculating at least a portion of the dewatered crude into a dehydrator. The dehydrator contains a heated dehydrated crude oil and the surface or adjacent thereto is maintained at a temperature sufficient to vaporize any water contacting the surface from crude oil to be treated in the dehydrator. It has been found important to maintain a substantially uniform temperature at or below the vaporizing surface in order to effectively treat crude oil for dewatering purposes. Significant temperature fluctuations are typically realized by dehydrators since heat enthalpy is removed in order to vaporize the water in the crude oil. Such fluctuations lead to process complications and upset and are therefore undesirable. The instant invention recognizes this limitation and substantially reduces foaming and provides for a smoothly running and efficient dehydration process.

Abstract: La présente invention concerne un dispositif de retenue (14) comprenant un harnais (15), un ancrage (16) reliés entre eux par une ligne vive (17). Ce dispositif comporte notamment un enrouleur (19) recevant la ligne vive (17) et pourvu d'un frein à inertie (18) retenant le dérouleur (19) lorsqu'il débite la ligne vive (17) à une vitesse dépassant une limite définie. Ce frein à inertie (18) est constitué de préférence, d'une part d'un carter dont la surface intérieure tient lieu de crémaillère (32) et d'autre part d'un cliquet (37) monté de façon à tourner autour d'un axe sensiblement parallèle à l'axe de rotation du dérouleur (19), mais décalé par rapport à lui. En l'occurrence, le cliquet (37) est sous charge de ressort tendant à déclencher le cliquet (37) de la crémaillère (32). Par contre, dès que le dérouleur (19) débite la ligne vive (17) à une vitesse dépassant une limite supérieure définie, le cliquet (37) s'enclenche dans la crémaillère (32), ce qui bloque le dérouleur (19).

Title: Optical path switching based differential absorption radiometry for substance detection
Inventor: SACHSE GLEN
IPC: G01N21/35
Filed: 1999-11-10
Abstract: A system and method are provided for detecting one or more substances. An optical path switch divides sample path radiation into a time of alternating first and second polarized components. The first polarized components are transmitted along a first optical path and the second polarized components along a second optical path. A first gasless optical filter train filters the first polarized components to isolate at least a first wavelength band thereby generating first filtered radiation. A second gasless optical filter train filters the second polarized components to isolate at least a second wavelength band thereby generating second filter radiation. Spectral absorption of a substance of interest is different at the first wavelength band as compared to the second wavelength band. A beam combiner combines the first and the second filtered radiation to form a combined beam of radiation.  A detector is disposed to monitor magnitude of at least a portion of the combined beam alternately at the first wavelength band and the second wavelength band as an indication of the concentration of the substance in the sample path.

Abstract: Method processor and processor-readable medium for reducing the level of feedback-induced noise in the output signal from an audio automatic gain control circuit are provided. The method allows for receiving a stream of pulses comprising an input signal to the automatic gain control circuit. The method further allows for receiving estimates of respective high and low frequency energy components of the input signal.  The respective high and low frequency components are averaged, e.g., over a respective sliding window. An energy scalar is calculated based on the ratio of a predefined target energy level over a combined value of the high and low frequency components. A relating action allows to compare the target energy level to the combined value of the high and low frequency components. Based on the comparison results, the calculated energy scalar is limited to within the two limit values. A subsequent relating action allows to compare the values of the averages of the high and low frequency components to one another. If the value of the high frequency average exceeds the value of the low frequency average, the energy scalar is reduced to a value sufficiently low to suppress the presence of feedback-induced noise in the input signal of the circuit, and generate an output signal with a correspondinglow level of feedback- induced noise. If the value of the low frequency average exceeds the value of the high frequency average, the energy scalar is applied to the input signal to generate an output signal scaled within the two limit values .

Title: Induction apparatus and method for determining dip angle in subterranean earth formations
Inventor: GAO LI
IPC: G01V3/28
Filed: 2002-08-06
Abstract: A method is disclosed for the determination of the dip angle of anisotropic earth formations surrounding a wellbore. Electromagnetic couplings among a plural of triad transmitters and triad receivers are measured. Each triad transmitter/receiver consists of coil windings in three mutually orthogonal ayes. The transmitter coils and receiver coils are oriented such that mutually symmetrical transmitter pairs or mutually symmetrical receiver pairs are equidistant from a centrally located receiver or transmitter, respectively. The measured signals from the created couplings are used to generate initial separate estimates of the dip angle of the formation. The two discrete determinations of dip angle are then averaged to arrive at a more accurate estimate that approaches the true dip angle in the formation.
