Patent CA-2287187-A1 (CA)
Title: Self-contained urethral catheter assembly with lubricating chamber
Inventor: WALLS JAMES A
IPC: A61M25/00
Filed: 1999-02-23
Abstract: A self-contained, self-lubricating catheter assembly is provided. A receptacle formed of two opposed flexible walls includes a main chamber and a lubrication chamber separated by a passage. A lubricant is provided in the lubrication chamber. A catheter is advanced from the main chamber through the lubrication chamber and picks up lubricant as it passes through the lubrication chamber. A catheter grasping mechanism, located proximate the exit from the lubrication chamber, permits advancement of the catheter out of the receptacle and resists movement of the catheter back into the receptacle. The receptacle also includes one or more finger holes therethrough to allow the user to retain the receptacle on one or more fingers, thereby allowing the hand to more readily position the receptacle during use while advancing the catheter.

Title: Method and equipment for attenuation of oscillation in a paper machine or in a paper finishing device
Inventor: KARHUNEN JOUKO
IPC: F16F7/10
Filed: 1998-04-22
Abstract: The invention relates to a method for damping vibration in a paper machine or in a paper finishing device by means of a dynamic damper which comprises an additional weight suspended from a vibrating object by means of a spring. In the method, the spring constant of the spring (3) of the dynamic damper and/or the mass (4) of the dynamic damper is/are changed by means of a control device (9) in order to tune the natural frequency of the dynamic damper. In an advantageous application of the invention, the vibration induced by rolls (1) which are in nip contact is damped by means of the damper so that the damper is tuned to a frequency that is substantially equal to a multiple of the rotational frequency of the roll that is closest to the natural frequency of the vibrating system. The invention also relates to an apparatus.

Title: Assaying nucleotides in solution using a fluorescent intensity quenching effect
Inventor: WU YUAN MIN
IPC: H01S/
Filed: 1998-06-30
Abstract: The invention provides a method for rapidly, economically and efficently sequencing and assaying nucleotides in a liquid medium using laser induced fluorescence of antisense probes, including PNA probes.  Fluorescent intensity of the resulting medium is inversely proportional to the hybridization efficiency of the probes with respect to the target sequence. The method is particularly advantageous in not requiring separation of unhybridized probes and hybridization complexes prior to detection. The method can be used to identify accessible regions in folded nucleotide sequences, to determine the number of mismatched pairs in a hybridization complex, and to map genomes.

Title: Packet scheduling in a communication network with statistical multiplexing of service classes
Inventor: MITRA DEBASIS
IPC: H04L12/56
Filed: 2000-02-28
Abstract: This Generalized Processor Sharing (GPS) is the basis for the packet scheduler of choice in IP routers and ATM switches of the future. The currently accepted approach for the design of GPS schedulers is based on deterministic QoS guarantees, which, it is generally accepted, is overly conservative and leads to limitations on capacity. To address this problem we develop a framework for GPS scheduling which is based on statistical QoS guarantees and statistical multiplexing. We give the design of GPS weights which maximize the coverage of operating points, and also the design of the connection admission control (CAC). The general framework is end-to-end, with two heterogeneous QoS classes coexisting with a third, best effort class. Each QoS  class has a specified delay bound together with a bound on the probability of its violation. An important objective is to maximize the bandwidth available to best effort traffic while just satisfying the guarantees of the QoS classes. To this end, we consider output regulated GPS scheduling which has the additional feature of limiting each connection's share of the bandwidth to a specified value, a design parameter which is determined by our analysis. The sources are subject to standard dual leaky bucket regulation.  For the design of the GPS weights we give procedures based on two key concepts, the realizable set and the critical weights. The realizable set is the union of all admissible sets of connections of both classes over all weights. One of the main contributions is a pragmatic design process by which most of the realizable set is realized by only two critical weights. In the benign case, the system is "effectively homogeneous"  and a single GPS weight suffices, while in the complementary "effectively non-homogeneous" case it is necessary to switch between the critical weights. The numerical results, which are for a single node with a wide range of traffic and QoS parameters, validate the design procedure and also show that there are substantial capacity gains from statistical multiplexing.

Title: Method for surface sizing paper with cellulose reactive and cellulose non-reactive sizes, and paper prepared thereby
Inventor: CENISIO MARCO FRANCO
IPC: D21H17/16
Filed: 1998-09-25
Abstract: There is disclosed a method for sizing paper by adding to the surface of the paper a sizing composition comprising cellulose reactive and cellulose nonreactive size. The sized paper perfoms better in ink jet printing than does paper that is the same except that the size composition contains only cellulose reactive size or only cellulose non-reactive size, when the printing is evaluated for at least one property selected from the group consisting of optical density, feathering, wicking, edge roughness and bleed. The sized paper also has higher toner adhesion, a higher coefficient of friction and a lower coefficient of friction bandwidth than does paper that is the same except that the size composition contains only cellulos reactive size. The paper is also capable of performing effectively in tests that measure its convertibility on state-of-the-art converting equipment and its performance on high speed end-use machinery.

Abstract: A method and system for managing a telephony connection on hold to reduce the use of resources within the telephony network and/or to allow the user on hold to place their telephony device into an on-hook state after they have been placed on hold. In two embodiments, a user of a telephony device who has been placed on hold can initiate a Smart Hold whereby their telephony device can be placed in an on-hook state while on hold and the user will be signaled when the call is to be removed from hold. This allows the user to perform other activities while a Smart Hold has been implemented, without the need to keep a telephone handset to their ear, for example. The freeing up of local loop resources can also be achieved. In another embodiment, the Smart Hold can be initiated by either party to a connection without requiring cooperation of the other party. In some embodiments, no toll charges or the like will be incurred while the Smart Hold is in effect.

Abstract: L'invention concerne un procédé de couplage d'un signal de télécommunications à une pluralité de câbles d'alimentation (15), chaque câble étant connecté dans une ligne à une barre omnibus (11, (13). Le procédé consiste à sélectionner l'un des câbles placé sensiblement au centre de la ligne et à coupler le signal de télécommunications au câble sélectionné ou à la barre omnibus se trouvant à proximité du câble sélectionné. Par "à proximité" on entend, de préférence, au niveau ou près du câble sélectionné, c'est-à-dire plus près du câble sélectionné que de tout autre câble relié à la barre omnibus. Lorsqu'un signal de télécommunications doit être connecté à une pluralité de câbles d'alimentation, l'un des objectifs est d'assurer une distribution plus ou moins égale de l'alimentation de signal de télécommunications, dans les câbles d'alimentation. Lorsqu'on effectue une connexion physique près de l'un des câbles centraux de la ligne, comme proposé ci-dessus, il est possible d'assurer que l'alimentation du signal est distribuée de manière aussi égale que possible.
