Title: Procede et appareil pour systeme de commande de reveil
Inventor: MOLLICONE DANIEL JOSEPH
IPC: H04L12/28
Filed: 2002-11-14
Abstract: L'invention concerne un procédé et un appareil se rapportant à un système de réveil qui permet de réveiller progressivement une personne pendant un certain temps afin de favoriser son mieux-être. L'utilisateur règle la commande du système à l'heure de réveil final voulue, soit l'heure à laquelle il doit être éveillé. Lorsque l'heure réelle atteint une heure d'introduction du stimulus (c'est-à-dire quelques instants avant l'heure de réveil final voulue), la commande du système provoque l'introduction du stimulus. Ledit système comprend en outre un système de détection qui mesure un paramètre corrélé au niveau du sommeil de la personne concernée (de préférence ses mouvements). Ce paramètre mesuré est ensuite utilisé dans une boucle de rétroaction pour réguler le niveau du stimulus éprouvé par ladite personne. Ainsi, l'utilisateur est réveillé progressivement pendant un certain temps entre le moment d'introduction du stimulus et l'heure de réveil final voulue, sans soumettre ses systèmes physiologiques à de quelconques chocs brusques.

Patent CA-2000388-A1 (CA)
Title: Full color liquid crystal display
Inventor: PRINCE JOHN C
IPC: G09F9/35
Filed: 1989-10-10
Abstract: ABSTRACT     A liquid crystal display provides a high quality color image and efficient energy utilization.  A layer of liquid crystal material is controlled by a transparent electrode matrix.  A matrix of (primary color emitting) phosphors, each in alignment with a transparent electrode, is fixed to a surface of a fiber optic plate.  A source of fluorescent energy excites the phosphors.   A filter located behind the fiber optic plate reflects visible light, both ambient and that emitted from the phosphors.  The fiber optic plate acts as a relay lens and prevents cross pixel color contamination while the generation of backlight by the phosphor conversion of fluorescent to visible energy is a highly efficient process.
Patent CA-2002809-A1 (CA)
Title: Optical determination of velocity
Inventor: CARR ROBERT J G
IPC: G01N15/14
Filed: 1989-11-10
Abstract: ABSTRACT      Particle velocity is determined optically through the use of crossed interference fringe patterns. The fringe patterns are produced by passing laser beams of distinct. wavelength along a common optical fibre and through two crossed diffraction gratings which are bonded to the free end of the fibre. Each diffraction grating is constructed in the manner of an interference filter so as to produce interference fringes at one wavelength but to transmit the other wavelength substantially uniformly across the grating. Other interference elements can be used in place of diffraction gratings and the use of a single diffraction grating is envisaged in certain circumstances. An indication of the sense of particle movement can be achieved by creating a fringe pattern of steadily increasing fringe spacing.

Title: Heat-resisting composition, secondary and composite binders for use in said composition and mixing method for same
Inventor: RICHARD GERARD
IPC: C04B35/66
Filed: 1989-12-27
Abstract: Refractory composition ready for hot or cold-hardening of the type comprising: (a) a filler of refractory mineral grains with high mechanical characteristics, for example silica, alumina or carbon; (b) at least one primary binder of the heat-hardenable type for agglomerating the grains of said filler; and (c) at least one secondary binder designed to improve and/or correct the faults of the primary binder. This composition is characterised in that the secondary binder is produced by saponification of a carbonated product whose acid value is sufficient for it to be modified by saponification, said secondary binder thereby becoming compatible with the primary heat-hardenable binder. The invention naturally also relates to a secondary binder and to the composite binder obtained by mixing the primary heat-hardenable binder with the secondary binder used in the refractory composition, as well as to a process for preparing said composition. The refractory composition according to the invention is suitable in particular for producing foundry moulds and mould cores, bricks and patches, and taphole clays for filling ports in blast furnaces.

Patent CA-2011406-A1 (CA)
Inventor: BERUBE MARTIN
IPC: B65D83/00
Filed: 1990-03-02
Abstract: A liquid dispensing apparatus comprises a container having a peripheral sidewall, a bottom wall mounted at a lower end of the sidewall and a closure removably mounted to an upper end of the sidewall. A flexible tight plastic bag is mounted at an upper end thereof between the closure and the sidewall and hangs in the container . The bag thus defines in the container first and second chambers which respectively contain a liquid to be dispensed and compressed air. A nozzle extends through the closure into the first chamber. A pressure regulating valve is mounted in the second chamber and defines therein upper and lower sub-chambers, with the bag being submitted to forces exerted by the compressed air contained in the upper sub-chamber. The pressure regulating valve ensures a substantially constant pressure in the upper sub-chamber and thus on the bag, whereas the lower sub-chamber acts as a reservoir for the upper sub-chamber. An admission valve extends through the bottom wall into the lower sub-chamber for filling the container  with compressed air. Safety valves are also provided in the upper and lower sub-chambers. Therefore, upon actuation of the nozzle, liquid contained in the first chamber is discharged from the container through the nozzle as the liquid is under pressure from the compressed air contained in the upper sub-chamber.

Title: Temperature control system for a heating oven using a glass-ceramic temperature sensor
Inventor: PAYNE THOMAS R
IPC: G01K7/00
Filed: 1990-11-15
Abstract: AN IMPROVED TEMPERATURE CONTROL SYSTEM FOR A HEATING OVEN  USING A GLASS-CERAMIC TEMPERATURE SENSOR                             ABSTRACT      A temperature control system incorporating a temperature sensor characterized by thermal inertia which causes the sensed temperature to lag the actual temperature during the transition from one operating temperature for the controlled environment to a different operating temperature.  This control system controls temperature as a function of setpoint temperature and the value of a temperature control variable representing the sensed temperature.  The value of the temperature control variable is set equal to the temperature sensed by the sensor during steady state operating conditions.  In response to a change in setpoint temperature, the system adjusts the value of the temperature control variable to compensate for the thermal lag of the sensor.
