Patent CA-2284467-A1 (CA)
Inventor: GVOZDANOVIC RADE
IPC: H04L12/54
Filed: 1999-10-04
Abstract: A traffic source emits packet-based traffic (ATM) carrying a plurality of variable bit rate calls. The traffic is managed by: measuring a parameter of the current traffic output from the source, using the measured parameter in a comparison with a parameter which is indicative of available capacity on the link; and providing a control signal for varying the operational state of the traffic source according to the comparison. The operational state can be varied by choosing a combination of a coding rate, selected from a range of coding rates, and selective use of silence suppression. A cell policing algorithm can be used, such as the GCRA. The system lowers transmission quality of voice traffic before lowering transmission quality of the data traffic, and uses silence suppression for voice traffic before using lower coding rates for the traffic source.

Title: Process for the production of engineered products in which curing of the wood is monitored ultrasonically and apparatus useful therefor
Inventor: HUNT ROBERT N
IPC: G01N33/44
Filed: 1999-12-03
Abstract: Cure of the binder used to produce a lignocellulosic composite material in a press is monitored by (1) inserting a transmitter probe and a receiver probe into the composite-forming mixture at parallel points; (2) passing an ultrasonic signal from the transmitter probe through the composite-forming mixture to the receiver probe; (3) measuring the pulse velocity of the ultrasonic signal; and (4) comparing the measured pulse velocity to that of a standard (i.e., velocity of pulse through a composite article in which the binder is completely cured). When the measured velocity and the velocity of the standard are equal, the composite article is removed from the press. This technique is particularly useful for monitoring the commercial production of composite and engineered wood products.

Abstract: L'invention concerne un détecteur de courbure de fibre optique (10) mesurant le degré et l'orientation d'une courbure dans une partie de longueur du détecteur (30) d'un ensemble de fibres (26). Dans une fibre à plusieurs coeurs (30, 32, 34), les coeurs (62, 66) sont groupés en paires non coplanaires. Un montage d'éléments optiques (28, 36, 38) définit à l'intérieur de chaque paire de coeurs (62, 66) deux trajectoires optiques (122, 124) variant le long de la longueur du détecteur (30): un coeur (62) d'une paire (62, 66) est inclus dans la première trajectoire (122), et l'autre coeur (66) est inclus dans la deuxième trajectoire (124). Une courbure générale de la région du détecteur (30) allonge un coeur (62, 66) par rapport à l'autre. L'étude de cette différence de longueur au moyen d'une interférométrie permet de générer des interférogrammes desquels on extrait le degré de courbure dans le plan de la paire de coeurs. On peut déduire une orientation de courbure à partir de données extraites de plusieurs paires de coeurs.

Title: Waveguide structures
Inventor: GODDARD NICHOLAS JOHN
IPC: G01N21/55
Filed: 1999-02-24
Abstract: A waveguide structure comprising a medium disposed of a sensing layer (21), a second layer of material (22) having a refractive index greater than that of the medium, and a substrate (24). The structure defines a waveguide capable of supporting an optical mode confined in a sensing layer. The medium is adapted for performing chemical or biological reactions within the medium which will result in a change of an optical property of the sensing layer of the waveguide. The thickness and refractive indexes of the layers are chosen such that an optical mode confined in the sensing layer will suffer substantially anti-resonant reflection as a consequence of the interface between the sensing layer and the second layer and the interface between the second layer and the substrate. Alternatively, the waveguide may comprise a low index sensing medium held between a superstrate and a substrate each of which has a refractive index higher than that of the medium. The waveguide may be capable of supporting two modes, such that one of the modes may be used as a reference during measurement of optical properties of a medium. The waveguide may be capable of supporting a leaky waveguide mode, the presence of the leaky waveguide mode being indicated by a peak of light returned from the waveguide.
