Patent CA-2201042-A1 (CA)
Inventor: MAKSYM GEOFFREY
IPC: A61B5/085
Filed: 1997-03-26
Abstract: The  variation  in  flow  resistance  of  the respiratory system (Rrs) is determined as an indicator of variations in airway calibre, by oscillating the system, for example at 6 Hz for 5-15 minutes and determining the variations  in  ratio  of  the  pressure  difference  (Prs) across the system that is in phase with flow, to flow ~. The variation in airway calibre may be employed as  a prognostic indicator in asthmatics and also to assess the efficacy of treatment.

Title: Method and equipment for determining the content of an element
Inventor: RAATIKAINEN JUKKA
IPC: G01N23/223
Filed: 1995-11-13
Abstract: The invention relates to a method and an equipment for determining the content of an element from a flowing sample mass (1) by utilizing x-ray fluorescence, in which method the sample mass (1) is irradiated with x-ray or gamma radiation; the radiation emitted by the sample mass is detected;  an energy-dispersive radiation spectrum of the radiation emitted by the sample mass is determined; and the content of the element is determined from the measured radiation spectrum on the basis of the intensity of the radiation spectrum window characteristic of this element.  In order that the method and equipment would also be applicable in field conditions, the method further comprises steps in which air temperature is measured in the air space between the sample mass (1) and a radiation detector or detectors (5); the first correction coefficient dependent on the measured air temperature is determined; and the determined content of the element is corrected by said first correction coefficient in order to compensate the attenuation of the characteristic radiation in the air between the sample mass (1) and the radiation detector or detectors (5).

Title: Method and apparatus for coding information
Inventor: TODD MARTIN PETER
IPC: G06T9/00
Filed: 1996-02-05
Abstract: A method of encoding invisible identification code into an image, which is highly resistant to degradation across communications links, and which does not require the presence of the original image for decoding, comprises analysing the image and determining strongly featured regions such as edges, and inserting code into such regions by altering the structure of the image in a predictable manner, as for example a concave elliptical insert centered on and aligned with an edge, which alteration is not visible to the eye. When decoding, areas of concavity are determined, and a correlation is performed with a predicted insert function to assess whether code has been inserted. A  hardware embodiment is described.
Patent CA-2214486-A1 (CA)
Inventor: NIEMIEC JAMES P
IPC: B41F23/04
Filed: 1997-09-03
Abstract: A method of and apparatus for curing or minimizing the problem of web "fluting" or "corrugating" in printed webs of paper printed on heat-set web-offset printing presses resides in spreading the web in its width-wise direction as the printed web exits from the ink drying and heat setting oven of the press and passes over the web cooling chill rolls downstream from the oven, thereby to hold the printed web in a flat and smooth condition until it is cooled and has taken a permanent set. The method and apparatus facilitate operation of the press at higher speeds and with lighter grades of paper than conventional, and provide for increased production efficiencies, lower costs, enhanced print quality, and access to new markets for web-offset printing.
Patent CA-2215690-A1 (CA)
Inventor: BOULANGER PIERRE
IPC: G01C11/02
Filed: 1997-09-16
Abstract: A mobile mapping system is designed to generate a geometrically precise three-dimensional detailed model of an unknown indoor environment.     There is no limit on the distance the mobile system may travel, nor on the type of details that can be mapped. The same design is used for environments ranging from simple office hallways to long winding underground mine tunnels. Surfaces and features can be mapped from images acquired by a unique configuration of different types of optical imaging sensors and positioning devices. This configuration ensures that all the information required to reconstruct the three-dimensional environment is included in the collected images. Provided a sufficient overlap between two-dimensional intensity images and combining such with three-dimensional range images, the method reconstructs an environment by adjusting a plurality of images simultaneously.

Filed: 1998-04-21
Abstract: An assembly for collection of a sample of a body fluid from a subject's body of the present invention includes a hollow tube defining an axis with an open end and a closed end. The hollow tube defines a chamber therewithin for receiving a sample of a collected fluid from a subject. The tube has a resilient closure disposed in the open end to close the chamber and to form a seal capable of maintaining a pressure differential between atmospheric pressure and a pressure less than atmospheric pressure within the chamber. The chamber contains an aliquot of an aqueous additive for treating the fluid sample. The chamber also includes a matrix formed from a fibrous material having capillary spaces therein for absorbing the aliquot of the aqueous additive and an aliquot of a water immiscible liquid with a density greater than about 1.07 grams per milliliter to encapsulate the aqueous additive absorbed on the matrix. The tube has a normally closed resilient valve disposed in the chamber to contain the aqueous additive, the liquid and the matrix between the closed tube end and the valve. I he valve is openable by centrifugation when there is a sample in the tube thereby allowing the lower density fractions of the sample and the aqueous additive to collect above the valve and to mix.
