Patent CA-2319295-A1 (CA)
Inventor: COVINGTON C ED
IPC: B64C27/22
Filed: 2000-09-14
Abstract: The present invention is for an improved rotating control system for use on tilt rotor aircraft and helicopters. Existing rotating control systems usually include a non-rotating swashplate and a rotating swashplate, both swashplates having a plurality of clevises, each clevis formed by at least two clevis arms. The clevis arms are disposed in a clevis plane, and an axis of symmetry is located in the clevis plane between the clevis arms. The clevises on the non-rotating swashplate are adapted to pivotally receive an actuator rod which has a rod axis defined by the actuator rod. The apparatus of the present invention includes an anti-rotation clip that is disposed between the clevis arms of each clevis of the non-rotating swashplate. The anti-rotation clip is either of unitary or multi-piece construction. The anti-rotation clip includes a wall portion and at least one restraining member that protrudes inwardly from the wall portion. The restraining members limit the rotation of the actuator rod about the rod axis.  This feature prevents wear and structural damage to both the actuator rod and the non-rotating swashplate.

Patent CA-2330734-A1 (CA)
Inventor: EHRLICH DONALD J
IPC: B60T17/22
Filed: 2001-01-10
Abstract: A novel system is provided for monitoring brake wear and stroke length. The system includes a brake chamber, a rotatable camshaft, a lever, a sensor, and an electronic control module (ECM). To determine brake wear, the sensor provides information to the ECM regarding a static position of the camshaft after a brake application relative to a starting static position of the camshaft prior to a brake application.      The ECM determines an angle of rotation of the camshaft and compares it with a predetermined angle of rotation of the camshaft. If the angle of rotation is greater than or equal to the predetermined angle of rotation, the ECM transmits an appropriate signal. To determine stroke length, the sensor provides information to the ECM regarding the maximum dynamic position of the camshaft during a brake application relative to a starting static position of the camshaft prior to a brake application. The ECM determines an angle of rotation of the camshaft, determines the stroke length required for such an angle of rotation, and compares the stroke length to a predetermined stroke length. If the stroke length is greater than or equal to the predetermined stroke length, the ECM transmits an appropriate signal.

Title: Impact resistant composite shell for gas turbine engine fan case
Inventor: ROBERTS PAUL D D
IPC: F04D29/52
Filed: 1999-05-20
Abstract: The invention relates to an impact resistant fibre composite shell for supporting an elastic containment belt after impact with a radially propelled broken fan blade of a gas turbine engine. A  conventional gas turbine engine can include a fan with a hub and fan blades disposed for rotation about a central axis. A life threatening and extremely damaging condition can result in flight if a defective fan blade breaks away from the hub and is propelled radially al high velocity under centrifugal force.  Conventionally a cylindrical fan case is provided about the periphery of the fan to compliantly contain a broken fan blade propelled radially outward from the rotating hub. Typically, the fan case includes an elastic blade containment belt of several Kevlar fabric plies for example, and a belt support shell disposed inside the belt, usually fabricated from aluminium. The invention provides an impact resistant fibre composite support shell of improved design. The fibre composite shell has two end support hoops each integrally manufactured with and structurally bonded to, centre breakaway lattice disposed radially adjacent the fan blades. The lattice permits the broken blade to cut a slit through the breakaway lattice passing to the elastic blade containment belt.  The slit lattice has sufficient residual post-impact strength to distribute post-impact loads imposed by the elastic blade containment belt to the end support hoops of the shell.

IPC: G09G3/36
Filed: 1999-06-04
Abstract: La présente invention concerne un système de commande de module d'affichage dans lequel les données de pixels numériques d'une image à afficher sont communiquées à une pluralité de pilotes de colonnes par rangée dans un format en série sur une pluralité de lignes de bus dédiées plutôt que sur une seule ligne de bus parallèle. Les données de pixels numériques d'un rangée complète d'image sont divisées en segments, le nombre de segments correspondant au nombre de pilotes de colonnes. Chaque segment fait l'objet d'une sérialisation et d'une transmission à un pilote de colonne correspondant, de manière telle que les données de pixels numériques d'une rangée entière soient transférées en même temps à chacun des pilotes de colonnes. Les pilotes de colonnes reçoivent les segments et remettent les données en parallèle. Les pixels sont alors envoyés sur un dénumériseur, de préférence deux par deux, dans lequel chaque pixel est converti en signal analogique rouge, vert et bleu. Un module d'échantillon analogique et de maintient de valeur échantillonne chaque signal analogique pour tous les pixels d'une rangée donnée de l'affichage, et stocke les signaux dans des premiers condensateurs d'une pluralité de paires de condensateurs de maintient et d'échantillon. Les paires de condensateurs de maintient et d'échantillon permettent aux signaux analogiques d'être échantillonnés et maintenus par rangée, de telle manière que lorsqu'un condensateur dans chaque paire stocke une des tensions analogiques rouge, verte et bleue pour une rangée suivante, l'autre condensateur transfère le signal de tension analogique aux électrodes des colonnes de l'affichage pour la rangée en court.

Title: Wait time prediction arrangement for non-real-time customer contacts
Inventor: HARRIS MICHAEL JOSEPH
IPC: H04M3/428
Filed: 2001-04-20
Abstract: The present invention is directed to a contact center and methodology for servicing non-real-time contacts. The advance time for the non-real-time contacts is determined by subtracting the time of service for an earlier item from the time of service for a later item. Items that are serviced immediately after certain types of predetermined events, e.g.. the queue containing the non-real-time contacts has no working agents; the queue is empty; the system clock is changed; and the system is rebooted are ignored in estimating the wait time for enqueued items. Using this methodology, accurate wait-time predictions are provided for more efficient management of the contact center.
