Title: Method of predicting kinematics for surface multiples
Inventor: DRAGOSET WILLIAM HENRY JR
IPC: G01V1/36
Filed: 2000-05-18
Abstract: Traveltimes of multiply reflected seismic events in a seismic profile or a model are determined from traveltimes for primary events. The traveltimes for the primary events may be obtained by ray tracing through a velocity model of the subsurface of by picking traveltimes from primary reflection horizons present in an actual seismic data set. The traveltimes for the primary events define a traveltime table for various combinations of source and receiver locations. The traveltime for a multiple corresponding to specified source and receiver positions is then determined by summing the traveltimes for primary events from the source to an interim point and from the interim point to the receiver: the correct location of the interim point corresponding to an actual multiple reflection raypath from the source to the receiver is the one that, according to Fermat's principle, has the minimum value for the sum. This method is applicable to all primary events, so that subsurface multiples as well as water bottom multiples can be determined. The method may also be used for determining traveltimes for higher order multiples.

Title: Sun optical limitation illumination detector (solid)
Inventor: DUBOIS JACQUES
IPC: G01S3/78
Filed: 2000-05-29
Abstract: An imaging system for obtaining an image of a field-of-view where high levels of light from an extraneous source may be present at one area and low levels of light present at other areas in the field-of-view. The imaging system has a lens to focus an image of the field-of-view onto a surface of a photodetector and an optical limiter is located between the lens and the photodetector. The optical limiter limits transmission of the high levels of light at areas onto which those are focussed by the lens but remains transmissive to the low levels of light at other areas. The imaging system is particularly intended for use in laser warning receivers where sunlight may be focussed on the optical limiter and blocked at the particularly area on which it is focussed, the optical limiter remaining transmissive to laser beams, even if intense, at locations other than where the sunlight is focussed allowing laser beams to be detected by the photodetector.

Title: Adenovirus mutants with deleted protease gene, complementing cell lines and corresponding vectors for gene transfer
Inventor: QUALIKENE WAHIBA
IPC: C12N15/861
Filed: 2000-02-24
Abstract: An adenovirus vector/packaging cell line system is disclosed, in which the vector replication is blocked by deletion of a single gene, which deletion does not interfere with any other viral functions. The deleted gene is the gene of the adenovirus protease. The protease is expressed in a complementing (packaging) cell line through a regulatable expression cassette which induces no toxic effects in the cells, thus making the generation and propagation of the vector easier and more efficient. As the deleted gene is highly specific of adenovirus, no complementation of the gene in transduced cells is expected, which increases the safety of the vectors for gene transfer purposes. Also disclosed is a system of generating recombinant adenovirus vectors by positive selection of recombinants deleted for the endogenous protease, gene which gene is cloned in another region of the adenoviral genome.

Abstract: The sun's solar energy is an unlimited source of power. There are numerous uses for solar energy from powering satellites, to watches, calculators and transportation signs on highways. Presented herein are 3 novel uses for a cell phone fitted with a Specialized Information Chip(SIC). The first model is a 100% solar powered cell phone. The second model is a hybrid 50% solar: 50% battery powered cell phone. The third model is a conventional battery operated cellular phone. For either of the three models an optional GPS can be an added feature. Models 1 and 2 both take environmental concerns into account like saving electricity consumption, decreasing wastage to the environment, increasing consumer usability and enjoyment. However, the differences they encompass allow for usage under diverse circumstances. The two modes focus on two different types of geographic locations around the world. The 100% solar mode would be utilized in very sunlit countries globally. The hybrid mode would come in effect in countries whereby sunlight is minimized. The regular mode would come in effect anywhere worldwide. For each of the models, the cellular phone is fitted with a specialized information chip that contain 2 large data bases of information specific for one city at a time. For example a chip for Toronto would contain data base 1 and data base 2. Data base 1 would consist of all the personal/business names, numbers and addresses. Data base 2 would consist of Points of Interest information e.g. accommodation, car rental, sporting events, entertainment, food establishments, etc. This chip would interact with the windows based operating system platform for the phone. This chip would be very user friendly for the consumer to pop in and pop out in a matter of seconds. The specialized information chip would be available for every large city in the world, allowing travelers and citizens alike more enjoyment from their leisure time.

Abstract: A blade for use with a housing to comprise a motor driven pump to be used to pump fluids. In particular, the blade is particularly useful because of high efficiencies in vacuum pumps, particularly, household vacuum cleaners having motors which may be advantageously powered using batteries. The blade involves a pair of generally conical walls enclosing therebetween a plurality of fluid flow passages. The fluid flow passages are defined in part by vanes extending between the two generally conical walls. The blade has a generally axial inlet and imparts centrifugal force to fluid elements. Because of the conical shape, the fluid moves in a direction having tangential components imparted by the vanes, radial components arising from centrifugal force and axial components because of the conical wall structure.      High efficiencies are obtained by contouring the generally conical walls in different planes, including convex curves in planes containing the axis of rotation and concave curves in polar planes concentric with the axis of rotation.
