Patent CA-2335249-A1 (CA)
Inventor: CEREO RICHARD J
IPC: H04B10/294
Filed: 1999-06-18
Abstract: Techniques for controlling the shape of the gain spectrum of an optical amplifier (13) based on the temperature and level of inversion of the amplifier's amplifying medium (20) are provided. An increase in temperature for an amplifying medium having a high level of inversion results in an increase in gain for longer wavelengths relative to shorter wavelengths, i.e ., a counterclockwise tilt of the gain spectrum, while an increase in temperatu re for an amplifying medium having a lower level of inversion results in the opposite effect, i.e., a clockwise tilt. These effects can be used to compensate for changes in the operating conditions of the amplifier, e.g., t o compensate for changes in signal powers. The effects of thermal tuning are especially useful in WDM systems employing multi-stage amplifiers.

Abstract: Selon l'invention, un système de karaoké mobile combine un signal provenant de l'audio externe (tel que la voix du chanteur interprétant une chanson dans un microphone) avec les données sur l'accompagnement musical de la chanson qui sont enregistrées en mémoire (essentiellement les données stockées dans une ROM) et émet le signal destiné à être transmis par un émetteur. L'invention est caractérisée en ce que suit: l'émetteur mobile sans fil pour le système karaoké est pourvu d'un décodeur supplémentaire, qui interagit avec une cartouche au moyen d'un bus d'interface; la cartouche est munie d'un dispositif d'identification et de codage à clés, couplé à la ROM et pouvant interagir avec le décodeur supplémentaire de l'émetteur à travers le bus d'interface. Le signal utilisé dans la transmission à destination du récepteur peut être un signal optique, un signal acoustique par ultrasons, un signal radiofréquence transmis par un champ électrique et/ou magnétique du champ proche de l'antenne lors de la suppression de la radiodiffusion; en variante, on peut utiliser la radiodiffusion sur une gamme de fréquences librement attribuée, avec transformation de ce signal sur le lieu de réception en une fréquence de la gamme de radiodiffusion et réception subséquente par un poste radio conventionnel. L'invention permet d'empêcher, d'une part, tout accès non autorisé aux données stockées dans la ROM de la cartouche et, d'autre part, toute utilisation dans le système karaoké de cartouches non autorisées (piratées), ce qui permet d'assurer le respect des droits d'auteur des auteurs de pièces de musique et des détenteurs légitimes de droits de propriété intellectuelle.
Patent CA-2342561-A1 (CA)
Inventor: KOYAMA JUNICHI
IPC: H04L9/32
Filed: 2001-03-29
Abstract: In a mobile communication system, when a mobile visitor terminal registered at a first network enters a second network, it sends a registration signal to a first exchange belonging to the second network. The first exchange sends a roaming start request signal to the first network. On receiving authentication information from the first network, the exchange writes it in a VLR (visitor  Location Register) storage. On the origination of a call on the visitor terminal, call information is written to a call information storage. A third exchange stores in an VLR holding node number storage the fact that the call information is stored in the first exchange. when the visitor terminal moves to the area of a second exchange, the second exchange sees, based on the content of the VLR holding node number storage, that the authentication information is stored in the first exchange, and obtains it. The second exchange switches connection thereto on the basis of the authentication information and call information.

Filed: 1999-09-30
Abstract: A method and apparatus for detecting the presence of a specific concentratio n of gaseous species within a calibrated range in a gas sample are disclosed. The ILS gas detection system (10) of the present invention simply comprises an ILS laser (12) and an optical detector (16). However, the potential or operational wavelength bandwidth of the ILS laser (12) is preferably entirel y included within one of the absorption bands or regions assigned to the intracavity gaseous species being monitored. Thus, within the calibtrated range, the presence of the gaseous species changes the output laser intensit y of the ILS laser (12). Consequently, only the intensity of the output of the  ILS laser (12) need be monitored in order to quantitatively determine the concentration of the absorbing gaseous species when using the ILS laser meth od of the present invention.

Abstract: Compositions and methods for controlling the population of insects are disclosed. The compositions include a feeding stimulant for a particular insect, an effective amount of a 1-arylpyrazole or nicotinyl insecticide to kill a desired insect, at a concentration which is not typically toxic when applied to a plant in the absence of a feeding stimulant and the insect consumes an ordinary amount of toxin during the course of normal feeding, bu t is toxic when applied in conjunction with a feeding stimulant which causes t he insect to consume more of the toxin than would normally be consumed during normal feeding. The use of normally non-toxic amounts of insecticides allows  one to minimize the residual insecticide present on the crops. Also, by usin g a selective feeding stimulant along with a normally non-lethal concentration  of insecticide, beneficial insects which are not attracted to the feeding stimulant are not effectively killed off, and detrimental insects which are attracted to the feeding stimulant are effectively killed off.
