Patent CA-2308572-A1 (CA)
Title: Call admission control method and apparatus for cellular systems
Inventor: SALMANIAN MAZDA
IPC: H04L12/56
Filed: 2000-05-16
Abstract: An improved call admission control method and apparatus is provided in which a MAC (or equivalent) layer parameter such as the FER (frame error rate) is used as a basis for call admission control. An estimate of a FER which would result should a requested session be admitted is made, and on the basis of this estimate, the session is either admitted or denied access. The estimate is made by combining a previous FER with a degradation which is expected should the session be admitted. The degradation is either determined experimentally, or can be updated in real time to reflect actual traffic patterns.

Title: Garment for use with an absorbent article
Inventor: SCHMITT ACHIM
IPC: A41B9/12
Filed: 1997-11-13
Abstract: The present invention relates to garments that have close body fit.      The garment of the present invention comprises an elasticized waistband, a front panel having first and second sections, a rear panel having first and second sections, a crotch region disposed between and joining the front panel to the rear panel and a pair of elasticized leg openings. The first section of the front panel has a greater resistance to streching in the lateral direction than the second section of the front panel. The first section of the rear panel has a greater resistance to stretching in the lateral direction than the second section of the rear panel. The crotch region is provided with a longitudinal stretch control member that is disposed along the longitudinal centerline of the undergarment. The longitudinal stretch control member limits the stretch of the crotch region in the longitudinal direction causing the crotch region to conform to a weare's skin surface.      A front stretch control member is disposed in the front panel and extends from the longitudinal stretch control member to the waistband. A rear stretch control member is disposed in the rear panel and extends from the longitudinal stretch control member to the waistband.

Abstract: Compte tenu d'une gamme de 1,5 Mbp et plus dans la région chromosomique 19p13.3 contenant le gène de Peutz-Jeghers, on construit un contraction de clones contigus continue de cosmide et élabore une carte de restriction. On recherche ensuite les gènes cartographiés dans cette région en faisant appel à une base de données EST et l'on détermine avec précision les emplacements de ces gènes. D'après cette évaluation de données biologiques plusieurs gènes à candidature hautement probable relativement au gène de Peutz-Jeghers sont spécifiés à partir des gènes ainsi découverts. A la suite d'analyses successives des modifications survenant dans ces gènes dans l'ADN de patients atteints du syndrome de Peutz-Jeghers, on a découvert que l'un de ces gènes, en l'occurrence le gène "LKB1", avait subi des modifications de manière spécifique chez lesdits patients. On a, de la sorte, découvert que les affections provoquées par une modification dans le gène LKB1 pouvait être examinées et traitées à l'aide de ce gène LKB1, d'amorces et de sondes basées sur sa séquence de base, de la protéine de LKB1 et d'un anticorps se fixant à cette protéine, etc.
Patent CA-2311894-A1 (CA)
Title: Radiation delivery system
Inventor: BARKER ANDREW J
IPC: A61B18/20
Filed: 2000-06-16
Abstract: A radiation delivery system scans radiation across a surface to be treated.  The scanner incorporates an input optical fiber, one end of which enters the scanning mechanism. The fiber is configured to match the output beam characteristics of a laser source, to which the remote end of the fiber is connected. The scanner includes an optical system to relay an image of the input fiber core onto an external surface to effect a surface treatment. The housing of the scanner incorporates features to ensure correct location of the core image relative to the external surface and may also incorporate a protective window to prevent ingress of material released or generated during the surface treatment process. The end of the fiber inside the scanner is stripped of all external protective sheathing, leaving only the core of the fiber with its immediate cladding layer. A mechanism is provided to effect lateral displacement of the fiber core along two orthogonal axes relative to the axis of the core imaging system. The corresponding displacement of the image of the fiber core provides the required scanning function over the external surface.

IPC: H04M1/57
Filed: 2000-07-06
Abstract: A calling party announcement apparatus and method for providing the identity of the caller in a non-synthesized, pre-recorded human speech. The invention detects and decodes the Incoming Caller Line Identification (ICLID) signal between ring signals before the called party answers the phone and announces the calling party's name and/or phone number. The called party answers the telephone or rejects the call before the receiver goes off-hook. Additionally, if the called party elects to accept the call, the call is answered, an individualized pre-recorded message is played back, or any other preferences selected with respect to the ICLID information is performed. An important aspect of the invention is the ability to play and record announcements and messages without the use of expensive and power-consuming digital signal processors. The invention provides for recording and locating pre-recorded announcements and predetermined preferences for call acceptance using the decoded ICLID information.

Title: Flame retardant emi shielding materials and method of manufacture
Inventor: FLANDERS WILLIAM I
IPC: H05K9/00
Filed: 1999-02-25
Abstract: A flame retardant, electrically-conductive EMI shielding material and method, the material being particularly adapted for use in fabric-over-foam EMI shielding gasket constructions. In construction, a generally planar, porous fabric member is provided as having at least an electrically-conductive first side and a second side defining a thickness dimension therebetween. A curable layer of a fluent, flame retardant composition is applied under a predetermined hydrodynamic pressure and viscosity to at least a portion of the second side of the fabric member. The hydrodynamic pressure and viscosity of the composition are controlled to delimit the penetration of the layer into the fabric member to a depth which is less than the thickness dimension of said fabric member. The layer then is cured to form a flame retardant surface coating on the second side of the fabric member such that the first side of said fabric member remains electrically-conductive.

Title: Low coefficient of thermal expansion cermet compositions
Inventor: FANG ZHIGANG
IPC: C22C29/00
Filed: 2001-01-31
Abstract: Low coefficient of thermal expansion (CTE) cermet compositions of this invention generally comprise a hard phase material and a ductile phase formed from a binder alloy, wherein the binder alloy is specially designed having a CTE that is closely matched to the hard phase material. Hard phase materials used to form low CTE compositions of this invention are selected from the group of carbides consisting of W, Ti, Mo, Nb, V, Si, Hf, Ta, and Cr carbides. The binder alloy is formed from a mixture of metals selected from the group consisting of Co, Ni, Fe, W, Mo, Ti, Ta, V, Nb, C, B, Cr, and Mn. In a preferred embodiment, low CTE compositions comprises WC as the hard phase material, and a ductile phase binder alloy formed from a mixture of Fe, Co, and Ni. The so-formed low CTE composition has a coefficient of thermal expansion that is less than that of conventional WC-Co at the same temperature and having the same metal content, thereby providing improved resistance to thermal shock and thermal fatigue related failure.

Patent CA-2338997-A1 (CA)
Inventor: FOLLOWS RICHARD R
IPC: A01N25/28
Filed: 1999-07-28
Abstract: Microcapsules formed from an aminoplast shell wall and an encapsulated ingredient or ingredients enclosed within the wall in which the wall contains a base-cleavable ester moiety. These capsules have been found to be sensitive to the presence of base such that in the presence of base, the capsule walls are relatively quickly disintegrated or degraded so as to produce a relatively quick release of the encapsulated materials. Microcapsules of this invention are particularly suitable for use in controlling insects having an alkaline gut such as certain lepidoptera in that the capsule shell wall may be designed so as to quickly disintegrate under the alkaline conditions present in the gut of the insect thus providing a microcapsule which is safe to handle but which is selectively effective against certain undesirable insects while not harmful to beneficial insects or insects which do not feed on the capsule materials.
