Patent CA-2192236-A1 (CA)
Title: Alarm and monitoring device for the presumption of bodies in danger in a swimming pool
Inventor: MENOUD EDOUARD
IPC: E04H4/00
Filed: 1995-06-02
Abstract: The invention relates to a device for monitoring the absence of motionless bodies in a swimming pool. Two cameras (1) provide for the permanent imaging of the bottom of the swimming pool. These images are first digitized and then processed by a computer. The superimposition of the two information permits analysis of substantially the entire the surface of the swimming pool in order to determine if a portion is masked by an obstacle. When such obstacle is detected, the duration of the presence of each masked pixel is analyzed. After a certain time delay, and for a minimum number of neighboring pixels, an alarm is generated.
Patent CA-2192964-A1 (CA)
Inventor: SUTHERLAND GEORGE
IPC: B01D17/02
Filed: 1995-06-23
Abstract: There is disclosed a system for separating oil and other immiscible contaminants from a liquid body containing the contaminants such as a water body. The system includes the use of a plurality of microporous hollow fibers (16, 18) which may be arranged in any number of arrangements such as bundles, intersecting arrangements, divergent patterns or in a mat-like arrangement or a combination of the foregoing. The hollow fibers are in communication with a source of suction (28) in order to draw the contaminant via the pores into the fibers for subsequent storage in a suitable container (20, 22). By incorporating acceptable means of density control a substantial amount of the hollow fiber surface area may be exposed to the contaminant thus increasing the extraction efficiency of the contaminant from the water body. The unit optionally may be self-contained. This system provides a substantial advantage over existing arrangements in that extraction efficiency is greatly enhanced in any number of environments.

Patent CA-2197061-A1 (CA)
Title: Printed fluid transport devices
Inventor: ALCOCK SUSAN
IPC: B01L3/00
Filed: 1995-08-08
Abstract: A backing sheet (101) is provided with a pattern of pathways (131, 132, 133) of e.g. silica or cellulose by a printing process (e.g., screen printing). There may be multiple pathways leading from an eluant application region (117) to a detection zone (116) and thence to a waste reservoir (118). Different pathways may have different fluid traversal times because they differ in length and/or material (e.g., nitrocellulose for slow traversal and fibrous cellulose for rapid traversal by an aqueous liquid). Thus analyte and reagents deposited at depots (112, 113) on different pathways are sequentially delivered to the detection zone. Reagents may be applied by printing. The detection zone may have an electrode assembly (105), also applied by printing, for detecting the effects of analyte.

Title: Optical sensors and method for producing fibre optic modalmetric sensors
Inventor: TAPANES EDWARD
IPC: G01D5/353
Filed: 1995-09-01
Abstract: An optical sensor and a method of producing the optical sensor is disclosed in which a singlemode fibre (14) is fusion spliced to a multimode fibre (18). The multimode fibre is cleaved or polished at a desired location from the splice (17) to localise the sensor, the end (15) of the multimode fibre can be mirrored to reflect radiation back through the multimode fibre so that the radiation re-enters the singlemode fibre for detection by a detector (24). Alternatively, a light source (22) can be coupled to the singlemode fibre and a further singlemode fibre connected to the multimode fibre at the desired location by fusion splicing so that a detector (24) can be connected to the further singlemode fibre for detecting radiation which is passed through the multimode fibre and which has had its property changed in the multimode fibre.

Title: Method and apparatus for checking automated optical system performance repeatability
Inventor: ARNONE JOSEPH
IPC: G02B21/26
Filed: 1995-09-12
Abstract: Tests characterize repeatability of a stage, microscope objective turret, the mechanical centration of optical paths, and parfocality of optical paths. The process includes selecting a lens with first magnification (62), inserting a calibration plate into the optical path (64), locating and centering a fiducial (66) by grossly positioning the stage (70), focus panning (72), determining the location of the center of the fiducial (74), and translating the stage to the center of the fiducial (76). After the fiducial center is recorded (68) the stage is moved in a star-like pattern (78) while imaging the fiducial (80) to help determine the lateral X and Y position of the center (82) for generating a data array (84) which is used in determining the repeatability of stage movement (88) by determining the maximum and minimum coordinate (86).

Title: Process for separating selected components from multi-component natural gas streams
Inventor: ELLIOT DOUGLAS G
IPC: C01B32/50
Filed: 1996-08-22
Abstract: A process for separating components of gas mixtures which have different hydrate forming characteristics which uses an aqueous liquid to absorb one the gases preferentially by attaining conditions slightly above the catastrophic point at which gas hydrates form. Specifically, the separation of gas mixtures containing light hydrocarbons and carbon dioxide is accomplished without significantly reducing the pressure of the carbon dioxide or without requiring significant amounts of heat energy for regeneration. A light hydrocarbon gas feed stream (2) is sent to a high pressure absorbing column (10) where it is contacted with an aqueous liquid stream (4). The liquid stream containing stripped carbon dioxide (8) is fed to a high pressure regeneration column (30) to remove the carbon dioxide as an overhead stream (34).
