Patent CA-2240274-A1 (CA)
Title: Absorbent article with apertured backsheet and fibrous super absorbent material
Inventor: COLES PETER
IPC: A61F13/49
Filed: 1996-12-09
Abstract: The present invention relates to breathable absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantyliner. According to the present invention, the articles are provided with an apertured backsheet for breathability. Typically such aperture backsheets are rendered substantially liquid impermeable in order to prevent soiling through the backsheet of the article. The absorbent core of absorbent article comprises in particular super-absorbent materials which transform the absolved liquid into a solid or semi-solid form such as a gel. Such super-absorbent materials are particularly desirable for benefits to the breathable absorbent articles in which they are used. However, they are typically provided in granular form. In combination with an apertured backsheet this form is prone to a particle loss through the apertures in the backsheet. Hence the present invention relates to breathable absorbent articles comprising non-granular super-absorbent material, preferably fibrous super-absorbent material.

Title: Statistical thesaurus, method of forming same, and use thereof in query expansion in automated text searching
Inventor: LU XIN ALLAN
IPC: G06F17/30
Filed: 1997-03-07
Abstract: A statistical thesaurus is built dynamically, from the same text collection that is being searched, allowing improved generation of expanded query terms.  The thesaurus is dynamic in that thesaurus records are collected, ranked, accessed, and applied dynamically. Thesaurus "records" are actually formed as indexed documents arranged in "collections". The collections are preferably distinguished based on text source. Each record has terms assembled in indexed groups which inherently reflect a ranking based on relevance to an initial query. After an initial query is received, the appropriate collection(s) of records may be searched by a conventional search and retrieval engine, the searches inherently returning records ranked by degree of relevance due the record indexing scheme. A record ranking scheme avoids contamination of relevant records by less relevant records. The record selection and the expansion query term generation processes are each divided into parallel threads. The separate threads correspond to respective text sources to enable the improved expansion query term generation to be provided in real time.

Title: Transfert d'appel dans un reseau telephonique cellulaire
Inventor: FOTI GEORGE
IPC: H04W8/02
Filed: 1997-05-07
Abstract: Afin de simplifier l'initialisation d'un transfert d'appel dans un réseau téléphonique cellulaire (10), la demande (212) de transfert vers un numéro C comprend non seulement une identification du numéro B (B) pour la station mobile appelée (14(1)), mais aussi un numéro d'identification (MSCID) du noeud de commutation (12) qui traite actuellement l'appel. En réponse à la réception de cette demande, l'enregistreur de localisation nominal (20) traite le numéro B, de façon à identifier un ou plusieurs numéros C pour réacheminer l'appel. L'enregistreur de localisation nominal détermine ensuite quels noeuds de commutation desservent actuellement les numéros C identifiés et génère directement un message de demande d'acheminement (214), qui comporte le numéro d'identification du noeud de commutation actuel reçu, destiné à chacun desdits noeuds de commutation. Cette action évite les actions de signalisation TIA IS-41 classiques consistant à retourner (114) les numéros C identifiés au noeud de commutation actuel et à générer un message de demande de localisation (116) destiné à être renvoyé à l'enregistreur de localisation nominal.

Abstract: A method for determining blood pressure of an artery within the wrist (22) of a patient utilizes a monitoring system (20) comprising a wrist assembly (24), monitor (26), cylinder (28), cable (30), and cable (32). The method includes the steps of applying a pressure to the artery, sensing pressure data produced by the artery, and deriving parameters from the sensed pressure data. The parameters are utilized for generating a first blood pressure value estimate using a first function of the parameters based upon a first range of pressure values, and by generating at least one second blood pressure estimate using at least one second parameter range. A blood pressure value is determined based upon the first blood pressure estimate, and at least one second blood pressure estimate.

Inventor: NICHOLS DEREK
IPC: A61G5/06
Filed: 1999-09-16
Abstract: A kit for converting a conventional wheelchair into an obstacle-mounting wheelchair, allowing an occupant to glide over obstacles such as sidewalk curbs. After removal of the large rear wheels and smaller front wheels of a conventional wheelchair, a pair of triangular belted support members are fitted to the frame of the wheelchair such that the frame hangs in a pendulum arrangement from the support members. The support members each have a rubber belt extending around their periphery on bearing mounts, and the wheelchair is propelled by an occupant grasping a portion of the two belts at the front of the support members and moving the belts downward. A pair of guide members are attached through spring-biased axles to a forward position on the wheelchair frame or a forward position on the support members. The guide members extend in an upward forward orientation, and rotate against bias when the front of the wheelchair encounters a curb or other obstacle. As they attempt to return to their unbiased position, the guide members lift the front part of the wheelchair, allowing the wheelchair to glide over obstacles with little reduction in forward speed.

Title: Noise reduction device and a noise reduction method
Inventor: TOMITA KAZUTAKA
IPC: G10L15/04
Filed: 1998-12-07
Abstract: A noise reduction method which reduces unpleasant residual noise even when movement to or from noise frames is frequent and the spectrum of each frame unevenly includes certain frequencies. In a spectral subtraction noise reduction method for producing an output by subtracting by a spectral subtraction filter an estimated noise amplitude spectrum from an amplitude spectrum created by orthogonal-transforming an input signal segmented to a predetermined frame length, the subtraction rate of the spectral subtraction filter is variable according to the estimated noise amplitude spectrum and an amplitude adjusting filter circuit (6) is used. The amplitude adjust filter circuit (6) multiplies the output produced by subtraction by the spectral subtraction filter for each frame, by an amplitude adjusting coefficient to produce a desired output. The amplitude adjusting coefficient is determined by the power of the amplitude spectrum (9) and the power of the estimated noise amplitude spectrum (10).
