Patent CA-2323586-A1 (CA)
Inventor: BAETEN GUIDO JOZEF MARIA
IPC: G01V1/36
Filed: 1999-03-25
Abstract: A method is disclosed for attenuating ground roll in seismic data signals. Seismic data signals are obtained from nearby seismic sensors. A difference filter is created that incorporates an estimate of ground roll differential move-out between the seismic sensors. The difference filter is then applied to the seismic data signals to produce a ground roll attenuated seismic data signal. The method can be used with one-pass and multiple-pass filter operations and can be used in connection with pairs of seismic data signals or with groups of seismic data signals from an areal pattern of nearby seismic sensors. The seismic data signals may be appropriately pre-processed and factors in addition to the ground roll differential move-out can be incorporated when creating the difference filter. The inventive method can be implemented in the time domain or in the frequency domain.

Patent CA-2331709-A1 (CA)
Inventor: SHEYNBLAT LEONID
IPC: H04W64/00
Filed: 1999-04-13
Abstract: La présente invention concerne une méthode et un dispositif permettant de déterminer la position d'un récepteur mobile dans un système de positionnement par satellite (SPS). Selon un exemple de ce procédé, on établit des informations relatives à un objet cellulaire qui comprennent au moins une information sur la position de l'objet cellulaire et au moins une information sur son identification. Ces informations servent à déterminer une altitude en fonction d'un émetteur d'installation cellulaire qui se trouve en liaison radio avec un système de communication cellulaire, lequel est couplé (et généralement intégré) au récepteur mobile SPS. La position du récepteur mobile SPS est calculée à partir de l'altitude extraite de l'information sur l'objet cellulaire. Selon un autre exemple de ce procédé, on détermine une pseudomesure d'altitude à partir d'une altitude estimée d'un récepteur mobile. Cette estimation d'altitude peut provenir d'une source d'information à base cellulaire dans un système à base cellulaire ou bien peut correspondre à une altitude moyenne de la zone de couverture radio par une station de base dans un réseau non cellulaire. La pseudomesure d'altitude peut être utilisée comme mesure redondante avec des techniques de détection et d'isolement pour déterminer si une pseudomesure au moins présente une défectuosité. En variante (ou en plus), une comparaison entre l'altitude estimée et une altitude calculée permet de déterminer l'état d'au moins une pseudodistance entre un satellite SPS et une récepteur mobile SPS. Dans une réalisation de cet exemple, la position est déterminée à partir d'un algorithme de solutions de position et, si les conditions reflètent un premier état (état non défectueux), cette pseudodistance est prise en compte dans l'algorithme de solutions de position.

Patent CA-2333296-A1 (CA)
Inventor: KAUFMAN HAROLD R
IPC: C23C14/46
Filed: 1999-05-05
Abstract: In accordance with one specific embodiment of the present invention, the apparatus (44) for sputter deposition within an evacuated volume (14) comprises a compact ion source (46) to generate ions (50, 52) into which an ionizable gas is introduced and from which ions leave with directed energies  near to or below the sputtering threshold, a sputter target (54) near that source and located within the beam of ions leaving that source, a grounded shield (58) surrounding the sputter target and defining that portion of the target which is to be exposed to sputtering, and a power supply to bias the target so that ions are attracted to and sputter the target. Particles sputtered from the target are deposited on a deposition substrate (64) separate from both the ion source and the sputter target. In the case of an insulating target, the target is biased with a radiofrequency power supply a nd the bias has a mean negative value rather than a direct-current negative value. The rate and energy with which the ions arrive at the target together  determine the rate with which that target is sputtered and the rate with whi ch the thin film is deposited on the substrate. In using a compact gridless ion  source, the high pressure required for generating ions is confined to the io n source and the gas load for pumping is reduced. For ion energies at or near the sputtering threshold, the sputtering from extraneous hardware is reduced  or eliminated. In addition, the target biases can be low enough to minimize the damage due to energetic neutrals that result from the reflection of energetic ions striking the target.

Inventor: AMAN JAMES A
IPC: G06T7/20
Filed: 1999-11-17
Abstract: A system (100) for tracking the movement of multiple objects within a predefined area using a combination of overhead X-Y filming cameras (25) and tracking cameras (24) with attached frequency selective filter (24f). Also employed are perspective Z filming cameras (25) and tracking cameras (24) with filter (24f). Objects to be tracked have been marked with a frequency selective reflective material, such as patches (7r and 71), sticker (9) and tape (4a). System (100) radiates selected energy (23a) throughout the area of tracking to reflect off the reflective materials. Reflected energy such as (7m, 9a and 4b) is then received by tracking cameras (24) while all other ambient light is blocked by filter (24f). Local Computer System (60) captures images from tracking cameras (24) and locates said markings. Using the location information along with preknowledge concerning the multiple objects maximum rate of speed and maximum size as well as calculated movement information, system (60) is able to extract from the background the portion of the unfiltered images that represent the multiple objects.

Title: 2er membrane and lumenal protein interaction yeast two-hybrid assay
Inventor: THOMAS DAVID Y
IPC: C12Q1/68
Filed: 2001-10-09
Abstract: The present invention relates to a new yeast two-hybrid system for the detection of interactions between membrane proteins and lumenal proteins of the endoplasmic reticulum. The yeast two-hybrid system of the present invention uses the IRE1 gene of yeast which is a key element in the endoplasmic reticulum unfolded protein response to signal the interaction between proteins within the endoplasmic reticulum. The IRE1 gene codes for a type 1 membrane protein Ire1p, that has a kinase in the cytosolic domain and it signals the presence of unfolded proteins in the ER by oligomerization and transphosphorylation, this in turn activates a RNaseL that has as its unique (so far) substrate the HAC1 messenger RNA, that codes for the transcription factor that binds to the unfolded protein response element and upregulates transcription of ER protein required for folding proteins within the ER. The yeast two-hybrid system of the present invention uses in-reading frame fusions of ER proteins to the N-terminal "protein sensing domain" of Ire1p to detect their interaction using Ire1p dimerization and the unfolded protein response system as a read out. This readout is made simpler by the use of reporter gene systems making the system suitable for mass screening of ER protein interactions.

Title: Analysis of downhole formation fluid contaminated by oil-based mud
Inventor: MULLINS OLIVER C
IPC: G01N21/35
Filed: 2000-02-15
Abstract: A method and apparatus is provided for determining a quality of downhole fluid. A series of measurements are taken of at least one parameter of borehole fluid that is indicative of oil-based mud filtrate contamination. By curve-fitting, the series of the measured parameter values are used to create an asymptotic curve indicative of the quality of the downhole fluid. One embodiment determines oil-based mud filtrate fraction in a borehole fluid sample. Another is used when there is little or no difference between the coloration of formation fluid and the coloration of OBM filtrate. Another determines gas-oil ratio of formation fluid corrected for oil-based mud filtrate contamination. Another determines the optical density of formation fluid corrected for oil-based mud filtrate contamination. Another determines conditions that would render optical density measurements invalid and sample capture premature. Another predicts the reduction of filtrate fraction for a specific extended pumping time. Another initiates sample capture when computed contamination fraction exhibits stable asymptotic convergence.
