Patent CA-2228231-A1 (CA)
Inventor: BROUNS AUSTIN JOHN
IPC: G01J5/28
Filed: 1998-01-27
Abstract: An infrared detector element includes a metallic patch which is positioned on the surface of an upper contact layer. A multiple quantum well ("MQW") infrared sensitive structure is positioned between the first contact layer and a second contact layer. The conductive contact layers are transparent to infrared radiation. A groundplane which is reflective to infrared radiation is positioned adjacent the second contact layer. A resonant cavity is formed between the metallic patch andthe groundplane. The thickness of this cavity is not greater than approximately one eighth of the wavelength of the incident infrared radiation within the cavity. The metallic patch functions to couple the incident infrared radiation into the resonant cavity wherein the E-field is oriented substantially normal to the plane of the MQW structure. A plurality of the detector elements can be used to form a single pixel and an array of the pixels can be used to form a complete infrared radiation imager.

Abstract: La présente invention concerne un procédé d'exploration du web d'Internet avec utilisation d'une machine du client comportant une interface graphique d'utilisateur et un explorateur d'Internet. Le procédé selon l'invention stocke, récupère et sort localement des objets d'information pour réduire le temps d'attente qui accompagne normalement le téléchargement de documents hypertexte ayant des éléments graphiques à résolution élevée. Dans un mode de réalisation, le procédé commence lorsqu'une page du web est affichée sur l'interface graphique d'utilisateur (70), cette page ayant un lien avec un document hypertexte situé de préférence dans un serveur éloigné. En réaction au fait que l'utilisateur clique sur le lien, l'explorateur (74) rend ce dernier actif pour demander ainsi le téléchargement du document hypertexte du serveur éloigné à l'interface graphique d'utilisateur du client (76). Pendant que le client attend une réponse, ou pendant le téléchargement, ou les deux, l'explorateur affiche un objet d'information (82) qui était auparavant en antémémoire.

Patent CA-2240780-A1 (CA)
Title: Steering input device
Inventor: EASTON DAVID JOSEPH
IPC: B62D1/10
Filed: 1998-07-14
Abstract: A vehicle steering input device includes a fixed housing, a steering input shaftrotatable relative to the housing by a vehicle operator, a hub non-rotatably mounted on the input shaft, a friction member frictionally engaging the hub, a resilient member biased to maintain the friction member in engagement with the hub member, a movable locking ring meshingly coupled to the friction member, and an electromagnet. When the electromagnet is energized it moves the locking ring into meshing engagement with the housing, thus limiting rotation of the friction member and creating an additional friction force which makes it more difficult to rotate the hub and the input shaft. The magnitude of this friction force depends on the bias of the resilient member and is not limited by the strength of the electromagnet.

Title: Procede de production d'ondes de cisaillement sismiques dans une formation souterraine
Inventor: LIENG JON TORE
IPC: G01V1/053
Filed: 1997-09-22
Abstract: On décrit un procédé de production d'ondes d'intersection sismiques dans une formation souterraine, dans lequel on utilise des poteaux, préalablement enfoncés dans la formation à des fins diverses ou que l'on a enfoncés aux fins de réalisation du procédé, en tant que milieu de transfert d'ondes d'intersection dans la formation. On a fait vibrer transversalement ces poteaux au moyen d'une masse oscillante, les oscillations étant conçues pour former des ondes polarisées principalement horizontales. Afin de réaliser la meilleure impression possible de la formation, on peut produire des ondes transversales dans une première direction au cours d'une première période, et dans une seconde direction, différente de la première, au cours d'une seconde période. Dans un autre mode de réalisation, on peut disposer la masse oscillante de manière à ce que celle-ci se balance parallèlement au poteau, afin de pouvoir produire des ondes de pression. On peut doter les poteaux d'une "jupe" et/ou de rebords s'étendant radialement, de manière à exécuter la meilleure fixation possible dans des formations meubles. Le cas échéant, on peut également introduire une sous pression artificielle dans le poteau, de manière à sauvegarder celui-ci contre toute pression s'exerçant autour de lui lorsqu'il vibre.

Patent CA-2269791-A1 (CA)
Inventor: WILLIAMS KEVIN G
IPC: G01N21/35
Filed: 1997-08-01
Abstract: A non-dispersive infrared (NDIR) multi-gas analyzer (405) has an optical element (950) that is positioned with respect to the axis of incident IR radiation such that it passes nearly all of the IR energy within a narrow band pass to one detector (540) and reflects nearly all of the IR energy outside the narrow band pass to another detector (535). Thus, the optical element (950) simultaneously functions both as a narrow band pass filter and a beam splitter, which transmits nearly all the IR radiation within a band pass and reflects nearly all the IR radiation outside the band pass. Additionally, the separation of the incoming energy can be achieved without an extended roll off. This allows using a reference transmission band that is very close to the absorption band of the gases of interest. It more specifically allows using a reference transmission band that is located between the absorption bands for hydrocarbons and carbon dioxide in an infrared analyzer that uses beam splitters.

Inventor: MCGILLIVRAY MILES
IPC: E21B4/00
Filed: 1999-05-28
Abstract: A method of earth drilling with a sealed bearing assembly and a sealed bearing assembly. A first step involves providing a bearing assembly that has a bearing chamber sealed with fixed sealing assemblies of axially aligned seals, including a primary seal and back up seals. The sealing assemblies are capable of withstanding an intended pressure differential. A second step involves drilling with the earth drilling assembly in a downhole environment in which pressure within the bearing chamber is at hydrostatic pressure with the relative pressure differential caused by pumping activity being borne by the fixed sealing assemblies. The bearings and back up seals positioned within the sealed bearing chamber operate under relatively low pressure thereby prolonging bearing and seal life.
