Patent CA-2269743-A1 (CA)
Title: Surface-cleaning doctor for use in a papermaking operation and associated method
Inventor: MARCHEGGIANI MARCO
IPC: D21G3/00
Filed: 1999-04-21
Abstract: A doctor system (20) and an associated method for cleaning the moving surface (30) of a papermachine component (22) which is begrimed or wetted by a paper web (28) moved around the surface utilizes an air nozzle (54) supportable in a stationary condition adjacent the surface of the papermachine component for directing a stream of air in the form of a knife from a source generally toward the surface to dislodge grime and water from the surface. The system also includes a collection receptacle (68) positionable adjacent the nozzle for collecting grime and water which are dislodged from the surface by the air knife for disposal.
Patent CA-2271362-A1 (CA)
Inventor: MATSUNAGA YASUHIKO
IPC: H04N7/173
Filed: 1999-05-07
Abstract: In a multiple-access communication system where a center station dynamically allocates upstream bandwidth to subscriber stations, upon receiving a reservation information from a subscriber station, the center station obtains an upstream resource usage information of a service corresponding to an identifier added to the reservation information from an upstream resource usage control means. When a value of a guaranteed upstream rate of the service is above a value of measured average upstream rate, an upstream bandwidth is allocated immediately upon receiving the reservation information. On the contrary, when the guaranteed value is below the measured average upstream rate value, the upstream bandwidth allocation to the reservation information is deferred, resulting in preventing degradation of service quality of other subscriber stations.
Patent CA-2273458-A1 (CA)
Inventor: ANISIMOV SERGEY NICOLAEVICH
IPC: A63F13/00
Filed: 1999-05-27
Abstract: Disclosed is a system and a method which enable playing a game or any part thereof and running various operations connected to the game or its stages, as well as running various operations not directly connected to the game. In these system and method, a stand-alone, portable game-playing device enabling the running of operations and/or games is incorporated with a data carrier for reading and recording of the information. The game-playing device may include data carrier authentication tools, a processing unit, a display, a data and commands input device, operation and/or game identification code reading tools, a micro-controller for running the operations and/or game play, memory, and buses connected with the processing unit, display, data and commands input device. In use, the data carrier is authenticated by means of the game-playing device. The possibility of operation and/or play is then determined using that game-playing device and data carrier and the operation and/or game is run by means of the stand-alone, portable game-playing device. The possibility of operation and/or play by means of the game-playing device is determined by reading identification codes from the data carrier, and transferring these codes to the micro-controller of the game-playing device for their identification. If the codes permit, the operation and/or game is then run. It is a particular feature of the invention that a game playing machine and associated card can be used for totally unrelated operations, such as a reader and identification card for access to a secure location, and so on.
Patent CA-2274845-A1 (CA)
Inventor: PRUTCHI DAVID
IPC: A61N1/37
Filed: 1997-12-11
Abstract: An implantable pacemaker (10) with apparatus for detecting capture or adjusting the strength or duration of pacing pulses by assessing (42) the mechanical evoked response that may be distinctly sensed through impedance sensing, pressure sensing, plethysmography or other suitable methods. When capture is to be detected or the strength or duration of the pacing pulses is to be adjusted, two pacing pulses are delivered to the heart in each cycle of a series of cardiac cycles. The first pulse is varied (138, 142) in strength or duration or both. The second pulse is maintained at a consistently high strength or duration to assure capture. The impedance of the heart is measured during a time window following the first pulse which is predicted to include a recognizable feature of the impedance waveform of the heart following a stimulating pulse. The magnitude of the first pulse is gradually changed until capture is lost. When the stimulation effect of the first pulse on the heart changes, the impedance measured during the window will change distinctly, indicating that a stimulus threshold has been detected.

Title: An optical filter for use in or with an optical amplifier
Inventor: ZIMMERMAN DONALD R
IPC: H04B10/17
Filed: 1999-08-04
Abstract: This invention relates to a method for filtering and a variable slope optical filter for in-line use with an optical amplifier. The filter has a wavelength response that is substantially linear in slope within a band of operation wavelengths of the amplifier; the slope of the filter in an operating band of wavelengths is between zero and a only one of a positive or negative number; furthermore the filter has an amplitude response that has an opposite and counter slope as a function of wavelength to that of a gain tilt of the amplifier within the operation band of wavelengths. Relative movement between the filter and a light beam carrying the optical amplifier signal is provided to vary the slope of the filter by means of varying the amplitude wavelength response of the filter.

Title: Architectures for communication networks
Inventor: HOBBS CHRISTOPHER L
IPC: H04L12/24
Filed: 1999-09-27
Abstract: A communication network which connects two data devices, such as routers, ATM switches, servers, over an agile transport network is described. The agile transport network has a plurality of agile nodes which reconfigure the bandwidth of the nodes in response to an external stimulus. The external stimulus can be a request for additional bandwidth from one of the data devices, or can be traffic information, which is interpreted by the nodes of the transport network. Each node has a contract manager which negotiates with contract managers at other nodes new paths for the additional bandwidth, and accordingly alters the connectivity map of a local agile switch.

Title: Multi-layer forming fabric with stitching yarn pairs integrated into papermaking surface
Inventor: WARD KEVIN J
IPC: D21F1/10
Filed: 1997-10-16
Abstract: A multi-layer papermaker's forming fabric has stitching yarns integrated into the papermaking surface. Each of a plurality of repeating units of the fabric comprises: a set of top machine direction yarns; a set of top cross-machine direction yarns interwoven with the top machine direction yarns; a set of bottom machine direction yarns; a set of bottom cross-machine direction yarns interwoven with the bottom machine direction yarns; and pairs of first and second stitching yarns. The stitching yarn pairs are positioned between pairs of top cross-machine direction yarns. The stitching yarns of each pair are interwoven with the top and bottom machine direction yarns such that, as a fiber support portion of the first stitching yarn is interweaving with the top machine direction yarns, a binding portion of the second stitching yarn is positioned below the top machine direction yarns, and such that as a fiber support portion of the second stitching yarn is interweaving with the top machine direction yarns, a binding portion of the first stitching yarn is positioned below the top machine direction yarns. The first and second stitching yarns cross each other as they pass below a transitional top machine direction yarn. Also, each of the binding portions of the first and second stitching yarns passes below at least one of the bottom machine direction yarns. In this configuration, the stitching yarns are completely integrated into the top, or papermaking, surface of the fabric, and therefore do not adversely impact the papermaking qualities of the fabric.
