Patent CA-2478738-A1 (CA)
Title: Wavelength locking for multi-wavelength laser source
Inventor: AHMADVAND NIMA
IPC: H01S3/13
Filed: 2004-08-18
Abstract: New systems and methods for wavelength locking for a class of multi-wavelength laser sources (MWLS) are provided. In this type of MWLS, the set of output wavelength channels are produced from a limited number of initial laser sources, such as a single laser or dual laser. In this invention, the initial lasers are locked based on the wavelengths of the outer channels in the set of output channels to provide tighter channel locking than that of a single laser source. This is mainly possible since the error in channel spacing caused by channel wavelength offset of the seed lasers is amplified by channel multiplication done in MWLS. This provides better resolution than applying wavelength locking to the seed lasers.

Patent CA-2482257-A1 (CA)
Inventor: MYRMAN MATTIAS
IPC: A61M13/00
Filed: 2003-04-04
Abstract: A device and an arrangement are disclosed, which create a powder Air-razor, which into an inhalation air volume de-aggregates and disperses a finely divided medication powder. The powder is generally loaded onto a dosing member intended for use with an inhaler. By means of an effort of sucking air through a mouthpiece connected to a nozzle, particles of the load of powder are gradually de-aggregated, dispersed and continuously released into the sucked air during a defined interval. The gradual de-aggregation and dispersal of the medication powder is generated by a relative motion introduced between the nozzle and the dosing member. The powder is generally loaded onto a larger area than the area of the air nozzle inlet. The nozzle may be positioned outside the dose area until an air stream has begun to flow into the nozzle by suction of air in an inhaling operation. Coincidental with the application of the suction or shortly afterwards a relative motion will begin such that the nozzle gradually traverses the bed of deposited powder. The powder Air-razor effect created by the shearing stresses and the turbulence provided by the high velocity air going into the nozzle inlet aperture when it hits the leading border of the contour of the powder is so powerful that the particles of particle aggregates at this point are released, de-aggregated, dispersed and subsequently entrained into the air stream going through the nozzle and through a mouthpiece into the airways of a user.

Title: Test for brake fluid age and condition
Inventor: PETTY JON A
IPC: G01N21/29
Filed: 2003-04-17
Abstract: A correlation is derived between a variable, defined as "virtual age", indicative of brake fluid's service age and/or mileage and the concentration of metal particle(s) content in the brake fluid. Virtual age is utilized to estimate the degree of degradation of the brake fluid. A reactive test strip (10) is used to measure the concentration of metal ions such as either coppe r, iron or zinc in the brake fluid in terms of a readily visible color change t o be observed by a test performer. The color chart (20) and a pre-set standard representative of the maximum concentration that is determined empirically t o correspond to the desirable "virtual age" threshold for advantageous brake fluid replacement. An automated embodiment of the invention includes an optical instrument and determined whether a fluid replacement is recommended without reliance upon human perception or judgement.

Inventor: ISENBERG NEIL E
IPC: H04M3/487
Filed: 2004-10-25
Abstract: In providing an information assistance service, an information assistance call from a user is placed in a call queue when operators are not available to answer the call.  In accordance with the invention, the call may be accorded priority in the call queue based on a measure of an excess wait time (EWT) incurred in a prior calls) from the same user. The EWT is defined as the wait time for the service in excess of a predetermined acceptable service wait time, which may be greater than or equal to zero. The queue prioritization in accordance with the invention increases the likelihood of answering the current call from a user, who experienced a EWT in a prior call(s), within the acceptable service wait time.

Title: Bonding of dynamic vulcanizates of fluorocarbon elastomers
Inventor: PARK EDWARD HOSUNG
IPC: B29C48/12
Filed: 2004-12-13
Abstract: A method of enhancing the adhesion of a thermoplastic fluoroelastomer composition to a substrate, and for making composite articles, involves applying a partially cured dynamic vulcanizate of a fluoroelastomer and a thermoplastic material onto a substrate, and curing the partially cured dynamic vulcanizate while it is in contact with the substrate. The partially cured dynamic vulcanizate is made by dynamically vulcanizing a fluoroelastomer in the presence of a thermoplastic and a curing agent under conditions of time and temperature such that the fluoroelastomer is less than completely cured. The cure is completed when the dynamic vulcanizate is in contact with the substrate.
