Title: Appareil d'evacuation utilise pendant un acte d'abrasion dentaire
Inventor: BRASSIL JOHN MICHAEL
IPC: A61C17/06
Filed: 1998-07-30
Abstract: L'invention concerne un appareil d'évacuation permettant de recueillir des substances particulaires produites au cours d'un acte dentaire, et en particulier pendant un acte d'abrasion à l'air. Cet appareil d'évacuation comprend une pompe à vide destinée à créer un courant d'aspiration, et un filtre situé en amont de cette pompe. Cet appareil d'évacuation comprend également un séparateur cyclone, placé en amont dudit filtre et destiné à éliminer l'abrasif, les dents, ou toute autre matière aspirée par ledit courant d'aspiration, afin d'augmenter la durée de vie du filtre et de permettre audit appareil de fonctionner à un courant d'aspiration maximum pendant de longs intervalles. Cet appareil peut en outre être utilisé avec une pièce à main d'évacuation grâce à laquelle on peut procéder à une évacuation intraorale et extraorale, ce qui permet de réduire les débris produits au cours d'un acte dentaire d'abrasion à l'air. On peut encore réduire ces débris en utilisant un système d'abrasion conjointement audit système d'évacuation, ce système d'abrasion comportant un dispositif de purge continue permettant d'éliminer les résidus d'abrasifs dans le tuyau et dans ladite pièce à main, évitant ainsi que ces abrasifs ne soient rejetés par bouffées.

Filed: 1999-07-27
Abstract: A crystalline structure (20, 60 or 220) and a device (120, 140, 180 or 270) which can be suited for use in any of a number of semiconductor or electro- optic applications, such as a phase modulator or a component of an interfereometer, includes a substrate (22, 62, 142, 182, 222 or 272) of a semiconductor-based material and a thin film (24, 64, 144, 186 or 224) of a crystalline oxide material epitaxially arranged upon the surface of the substrate so that the thin film couples to the underlying substrate and so that the geometries of substantially all of the unit cells of the thin film are arranged in a predisposed orientation relative to the substrate surface.  The predisposition of the geometries of the unit cells of the thin film is d ue to a stressed or strained condition of the lattice at the interface between the thin film material and the substrate surface and is responsible for a predisposed orientation of a directional-dependent quality, such as the dipo le moment, of the unit cells. The predisposed orientation of the unit cell geometries enables a device within which the structure is embodied to take beneficial advantage of characteristics of the structure during operation.</ SDOAB>
Patent CA-2340436-A1 (CA)
Inventor: LIDEN FREDRIK
IPC: H04B10/032
Filed: 1999-08-05
Abstract: An optical communication line having optical fibre amplifiers including a pu mp laser can be configured to suppress the transmission of optical signals, for  example when used as a duplicate line for redundancy, by reducing the power of the pump laser. In order that the portion of the line downstream of the amplifier can be monitored for fibre breaks causing only negligible crosstal k with a parallel working line and with the elimination of the risk of mistaki ng reflections from a working line for light emitted by the standby amplifier, light emitted by the standby amplifier is modulated by a low frequency contr ol tone. Preferably the pump laser current is modulated by a low frequency signal. The modulated laser light causes modulation of the ASE generated in the amplifier to create a control tone. Monitoring means disposed at the end  of the optical line detect this control tone and use this as the criteria fo r a functional connection downstream of the amplifier.

Title: Method and apparatus for electromagnetic emissions testing
Inventor: CARPENTER DARREN JAMES
IPC: G01R29/08
Filed: 1999-08-23
Abstract: The likelihood of a system complying with EMC regulations is determined for a system comprised equipment units which individually radiate electromagnetic emissions. The intensity contribution of the electric field from each of the equipment units is calculated and a phase difference is randomly assigned to each of the components repeatedly in order to generate distribution of electric field values between a minimum possible electric field value and a maximum possible electric field value. This distribution is then statistically analysed to determine a compliance probability.
Patent CA-2348381-A1 (CA)
Inventor: BLOUIN ALAIN
IPC: G01N29/24
Filed: 1999-11-03
Abstract: A method and an apparatus for non-contact and non-invasive characterization of a moving thin sheet and in particular of a paper web on a production line. The method uses a laser for the generation of sonic and ultrasonic waves in the thin sheet and a speckle insensitive interferometric device for the detection of these waves. The generation is performed in conditions to avoid damage impeding further use of the sheet.  When the generation and detection spots overlap, the method provides a measurement of the compression modulus. When the generation and detection spots are separated by a known distance and plate waves (Lamb waves) are generated and detected, the method provides a measurement of the in-plane modulus and of the tension applied to the sheet. By detecting waves propagating in various directions, either by rotating the detection sensor head or multiplexing the signals provided by several detection or generation locations, the anisotropy of the in-plane modulus is determined.
