Patent CA-2408578-A1 (CA)
Title: Laser pulse shaping device
Inventor: MANSBRIDGE JOHN
IPC: G02F1/03
Filed: 2001-05-10
Abstract: There is provided a pulse shaping apparatus for shaping an input optical pulse into an output optical pulse having substantially constant optical power. The apparatus includes a modulator, which acts upon the input optical pulse under the control of a control signal, and a sampling means, which takes a sample of the incoming optical pulse for further processing. In a feedback configuration, the modulator acts on the incoming pulse under the control of an error signal, the incoming pulse is then sampled, the sample processed and the error signal generated from the processed sample. In a feed-forward configuration, the incoming pulse is sampled first, the sample processed and the modulator acts on the incoming pulse under the control of an error signal resulting from the processing steps. Alternatively, an output optical pulse having substantially constant optical power can be generated by directing the incoming optical pulse through a limiting medium that saturates at a predetermined power level.

Filed: 2001-12-12
Abstract: A crimping apparatus (10) for receiving a circular array of die segments (60) for radially inwardly crimping an end fitting onto a hose includes an upper plate assembly (12) and a lower plate assembly (13). The upper plate assembly (12) includes an upper back plate (14) attached to an upper front plate (16) by a plurality of fasteners (38). The lower plate assembly (13) includes a lower back plate (18) attached to a lower front plate (20) by a plurality of fasteners (38). The upper back plate (14) and upper front plate (16) cooperate to form a first hinge portion (75, 90) and the lower back plate (18) cooperates with the lower front plate (20) to form a second hinge portion (30, 48). The arrangement allows the upper plate assembly (12) to pivot about the lower plate assembly (13) at the first (75, 90) and second (30, 48) hinge portions. The crimping apparatus (10) is advantageous because it allows the passage of large elbow hose fittings that could not pass through the central bore of a conventional die cage.

Inventor: THOMSON BRUCE
IPC: H01J49/40
Filed: 2001-12-14
Abstract: La présente invention concerne un procédé et un appareil permettant d'effectuer de multiples étapes de sélection ou d'analyse de masse. Cette technique est principalement fondée sur le déplacement d'ions dans différentes directions, à travers des composants séparés d'un spectromètre de masse. Afin d'effectuer différentes étapes, un ion précurseur est choisi dans un premier sélecteur de masse, puis passe à travers une cellule de collision, afin d'induire une fragmentation ou une réaction avec un gaz, en vue de créer des ions fragments ou des ions produits. Les ions produits créés passent ensuite de nouveau dans le premier sélecteur de masse, puis de préférence de nouveau dans un piège à ions en amont. Les ions produits créés passent ensuite encore une fois dans le premier sélecteur de masse, afin de choisir un ion produit souhaité, en vue d'une fragmentation ou d'une analyse ultérieure. Ces étapes peuvent être répétées un certain nombre de fois. Une étape d'analyse de masse finale peut être effectuée soit dans un système d'analyse à temps de vol, soit dans un autre analyseur de masse. Cette invention permet à des spectromètres de masse triple quadripôle et à des spectromètres de masse QqTOF (quadripolaires/à temps de vol) classiques d'effectuer de multiples étapes MS.

Patent CA-2433661-A1 (CA)
Inventor: MORYS MARIAN
IPC: G01V11/00
Filed: 2003-06-26
Abstract: An apparatus and method for reducing crosstalk and other noise sources in downhole tools is disclosed. Due to confined space in the downhole tool environment and the fact that the transmit path utilizes significantly more electrical power than the receive path, electromagnetic noise easily couples between adjacent circuitry. The specification discloses a phase-reversal element that can selectively allow the received signal to pass unaffected, or which can cause a phase reversal of the received signal. A digital signal processor samples the received signal, which after receipt but before sampling has noise induced thereon. Thereafter, the digital signal processor samples the phase reversed received signal, which likewise has the noise induced thereon after receipt but before sampling. Subtracting the first sampled signal from the second produces a resultant signal in which the noise is substantially reduced.
