Inventor: HERB WILLIAM R
IPC: G01P15/10
Filed: 2000-02-22
Abstract: L'invention concerne un capteur destiné à détecter les vibrations. Ce capteur comprend une source lumineuse servant à émettre une lumière laser, une première fibre optique connectée à la source pour émettre la lumière laser, un oscillateur capable de recevoir la lumière laser émise et de réfléchir la lumière comme une lumière à fréquence modulée; une seconde fibre optique placée de manière à capter la lumière à fréquence modulée afin d'émettre ladite lumière; et un détecteur de fréquence modulée destiné à recevoir la lumière à fréquence modulée depuis la seconde fibre optique et à émettre un signal en réponse à la vibration de l'oscillateur. Dans un meilleur mode de réalisation, le détecteur de fréquence modulée comprend aussi un fréquencemètre servant à déterminer la moyenne de cycles par unité de temps afin d'émettre un second signal en réponse à la température de l'oscillateur. Les fibres optiques peuvent former un ensemble de différentes fibres disposées de manière à émettre la lumière laser et la lumière à fréquence modulée. Elles peuvent aussi être constituées d'une même fibre capable d'émettre à la fois la lumière laser et la lumière à fréquence modulée. Le meilleur oscillateur comprend une puce munie d'un microfaisceau montée sur un fin porte-à-faux en silicium de manière à ce que la déviation du faisceau perpendiculairement à la surface de la puce modifie la tension dans le microfaisceau et change sa fréquence de résonnance. Dans un autre mode de réalisation, le microfaisceau comprend une fine couche métallique afin de créer une structure dimorphe.

Patent CA-2384233-A1 (CA)
Title: Programmable optical multiplexer/demultiplexer
Inventor: MAROM DAN MARK
IPC: H04B10/27
Filed: 2002-04-29
Abstract: A programmable optical demultiplexer can independently assign every input optical channel in a WDM optical communications signal to depart from any desired output port. The demultiplexer device can also be operated in the reverse direction, and thus achieve programmable optical multiplexer functionality, by accepting different wavelengths at each of multiple input ports and efficiently combining the wavelength channels at the multiplexer output port. The programmable multiplexer/demultiplexer device has an optical arrangement for spatially dispersing the optical wavelengths, and tunable micro-mirrors for beam steering each channel independently. Controlling the beam reflection direction determines the connectivity between the input and output ports at the wavelength level.

When the pressure to the inlet (30) exceeds a second predetermined value (42) the pressure to an inlet (31) of the impact device (5) is controlled inversely proportionally to the pressure to the inlet (30) of rotation motor (7).
Patent CA-2391973-A1 (CA)
Inventor: WILSON RICHARD J H
IPC: A23L35/00
Filed: 1999-11-18
Abstract: A process for the direct hydrogenation of hop resin acids in the absence of a liquid, organic solvent by reacting the hop resin acids with hydrogen in the  presence of a noble metal catalyst at a temperature at which the resin acids  are sufficiently fluid to allow easy mixing with the catalyst and suitably facilitate the hydrogenation reaction. Alternatively, the necessary fluidity  may be achieved at relatively low temperature by subjecting the reactants to  a high pressure of CO2 gas such that the quantity of this gas that dissolves into the resin is sufficient to substantially reduce its viscosity, the pressure of the CO2 gas being either less than the liquefaction pressure at temperatures below the critical temperature or less than that which would cause the density to exceed that at the critical point for temperatures abov e the critical temperature. A further variant allows for the hydrogenation of the resin acids as a suspension in water and is considered most appropriate for the processing of resins that are of relatively more viscous nature in circumstances where the application of a high pressure of gas may not be possible for mechanical reasons. Particularly useful applications for the process are the conversion of iso-.alpha.-acids to tetrahydroiso-.alpha.-aci ds and rho-iso-.alpha.-acids into hexahydroiso-.alpha.-acids. The resinous products of the hydrogenation process may be readily converted to aqueous, alkaline solutions suitable for use in brewing beer. The process may also be  worked in a continuous manner, wherein hop resin acids in suitably fluid sta te and under high pressure are contacted with hydrogen gas and the resultant mixture passed over a bed of noble metal catalyst particles. The necessary fluidity is achieved either by heating the hop resin acid or by dissolving C O2 gas into it or a combination of both. The resinous product of the hydrogenation reaction is collected by depressurisation of the fluid exiting  the catalyst bed, conveniently causing release of any excess dissolved gas.< /SDOAB>

IPC: H01R33/88
Filed: 2000-11-17
Abstract: Two lamp sockets on a wiring board behind a switch assembly have identical geometries. Each comprises a through-hole with a polarizing feature. Plural discrete contact pads are disposed on the board surface spaced apart around the margin of each through-hole.  Plural discrete conductor traces are printed on the board surface to run from the respective contact pads. Each socket can accept either a first model or a second model of lamp assembly to make either socket a status indicator for the switch assembly or a nighttime illumination socket. A common wiring board can thereby serve different requirements for the locations of status indicator and nighttime illumination lamps.
