Title: Systemes de radiocommunication microcellulaires
Inventor: GRANDHI SUDHEER A
IPC: H04W24/10
Filed: 1995-06-28
Abstract: L'invention a pour objet un système de radiocommunications microcellulaire (microsystème). Ce système est configuré pour réutiliser des canaux de fréquences radio qui sont attribués pour être utilisés dans un système radio cellulaire (macrosystème) dans le même voisinage. Le microsystème comporte une liste (52) de tous les canaux de fréquences qui sont utilisés dans toute microcellule du microsystème. Dans chaque microcellule du microsystème, une caractéristique du signal, par exemple, la force du signal reçu, de chaque canal de fréquence est mesurée de manière répétée lorsque le canal n'est pas actuellement utilisé dans une microcellule quelconque du microsystème. En outre, ces mesures sont utilisées par un dispositif de balayage (56) du spectre de la cellule pour déterminer une préférence statistique (60) à long-terme pour ré-utiliser un ensemble préféré de canaux de fréquences dans cette microcellule. Pour chaque microcellule, un gestionnaire (58) de spectre de cellules donne aux canaux de fréquences dans l'ensemble préféré un ordre à court-terme en vue de leur utilisation effective en fonction des mesures fréquentes de la caractéristique du signal pour la microcellule, que le canal soit utilisé, ou non, dans toute autre microcellule.

Title: Expandable Column Positioning Mechanism
Inventor: MATSUMOTO TADASHI
IPC: H01Q1/12
Filed: 1996-12-11
Abstract: The expandable column positioning mechanism of the present invention was developed to improve the reliability of the operation thereof by reducing the number of components without the need for movable elements. An expandable column is accommodated in a fixed frame so as to freely axially extend therefrom and retract thereinto. The expandable column has a plurality of holes longitudinally spaced therein. An actuating piece extends from an end of the fixed frame. The actuating piece has resiliency or elasticity and is pivotally mounted on the fixed frame about a connecting portion thereof. The actuating piece has a pin extending therefrom for engaging the holes of the extendable column.      The expandable column is positioned by the engagement of one of the holes with the pin. The hole and the pin are disengaged by pivoting the actuating piece away from the expandable column, so that the expandable column can be extended or retracted.

Patent CA-2205193-A1 (CA)
Inventor: D AMBRUSO CARON S
IPC: A61M25/01
Filed: 1997-05-13
Abstract: A first catheter surrounds a guidewire, with the first catheter and guidewire each having a distal portion  emplaced  in the  cardiovascular  system of  a patient.  By this invention, the first catheter may be removed without displacing the guidewire.  To accomplish this,  one may advance an exchange catheter into the patient to a desired position where the exchange catheter completely surrounds the guidewire distal end and, in turn, is surrounded along part of its length by the first catheter.   One causes a proximal end portion of the guidewire to project outwardly through a longitudinal slit of the exchange catheter, so that the proximal end of the guidewire may be grasped.   By this means the guidewire may be retained in the desired position as the exchange catheter is advanced into its position within the first catheter and surrounding the guidewire.  One then withdraws the first catheter from the patient, while causing the exchange catheter to be held relatively stationary.   Thus the guidewire within the exchange catheter  is  also  retained  in  relatively  stationary position without the need for retention of the guidewire by manual grasping.  Also, the guidewire may be replaced through the exchange catheter.

Patent CA-2210518-A1 (CA)
Title: A device and process for generating and measuring the shape of an acoustic reflectance curve of an ear
Inventor: COMBS JEROME T
IPC: A61B5/12
Filed: 1996-01-26
Abstract: A device or a process for analysis of acoustic reflectance of components of an ear involves directing, into the ear canal, acoustic waves covering a range of frequencies including resonance frequencies of ear components such as the tympanic membrane. Measurements are made without pressurizing the ear canal and contact between the device and the ear does not need to be air-tight. Accordingly, the patient experiences essentially no discomfort from use of the device. The device detects and combines the incident and reflected waves to produce what is called an acoustic reflectance curve. The shape of a region of the acoustic reflectance curve is electronically measured in order to obtain an indicator of ear condition which is substantially independent of a line of sight between a sound source and the tympanic membrane. This indicator is based on a mesurement of the resonance characteristic, or freedom of motion, of the tympanic membrane or other ear component being analyzed. One such measurement is the rate of change of the acoustic reflectance with respect to frequency. Since resonance typically causes a null to appear in the acoustic reflectance curve, this measurement of the rate of change is particularly informative if measured around the null. The rate of change measured around the null may be presented as an angle measurement, a gradient or slope measurement, a width measurement, or other form of measurement of the shape of the null. In one embodiment, the steepest slopes on either side of a null are used to define an angle, herein called a spectral gradient. Diagnosis of an ear pathology, such as abnormal pressure or presence of fluid in the middle ear or such as conductive hearing loss, may be based on this measure alone. Because of the rate of change of an acoustic reflectance measurement is relatively constant for a given ear, regardless of the quality of the line of sight to the tympanic membrane, the effect, if any, of user training on such measurements is significantly reduced. Accordingly, the process and device of the invention are useful in many kinds of diagnostic situations with respect to ear pathology, but particularly in those involving screening of the ears of young children for common pathologies such as otitis media, even by untrained personnel.

Title: Method and apparatus for detecting artifacts using common-mode signals in differential signal detectors
Inventor: LYSTER THOMAS D
IPC: A61B5/308
Filed: 1996-02-29
Abstract: The present invention is a novel method and apparatus for analyzing the composite input signal and determining whether the amount of common mode signal in the composite signal is unacceptably high; thus, precluding an accurate diagnosis of the differential mode signal of interest. The steps of the presently claimed method are, first, to separate the composite signal input into intermediate signals that are known functions of the differential mode signals of interest and common mode signals (or a suitable combination thereof). In one embodiment of the present invention, the intermediate signals are cross-correlated to produce a measure of correlation between the intermediate signals. This measure is then compared with a threshold value. If the comparison is favorable, then the data is presumed to be uncorrupted and analysis of the signal representing the differential mode signal continues.  Otherwise, the data is presumed to be corrupted and analysis of the signal data is inhibited. In another embodiment, the intermediate signal representing the common mode signal is itself compared against a threshold value without first cross-correlating with the intermediate signal that represents the differential mode signal. If the comparison is favorable, then it may be concluded that the potential for corruption is small and analysis of the intermediate or composite signal is continued.

Abstract: A method is provided for cleanup of the fine fraction (<= 1.0 mm) of sandy soils contaminated with heavy oil/ bitumen, chlorides and heavy metals and for recovery of heavy oil/ bitumen from aqueous slurries of these soils. The method includes the steps of screening the sandy soil, preparing hot aqueous slurry of prescreened soil, screening and heating the slurry in a slurry heater, separating oily froth and contaminated process water from the slurry of precleaned sandy soil and thickening the precleaned sandy soil in a separating/thickening vessel followed by reprocessing the thicken slurry of precleaned sandy soil. Reprocessing generates some additional quantities of residual oily froth and contaminated process water from the sandy oil which is washed with fresh water, dewatered and renders sandy soil that meets the criteria for agricultural soil in Canada.
