Patent CA-2307237-A1 (CA)
Inventor: TREAT MICHAEL R
IPC: A61B10/00
Filed: 1998-10-23
Abstract: A flexible or rigid endoscopic biopsy device provides for the taking of multiple biopsy specimens from different sites, and for separating and storing these specimens in a partitioned container. The distal end of this device consists of a grasper which can bite or cut off a bit of tissue. The proximal end of the inner tubing is connected via the handle end of the device to a multi-chambered specimen storage device, which is itself connected to suction.  The storage device has several chambers, each of which may be lined up with the inner tubing, by rotating the top of the storage device. After some or all of the storage subpartitions have been filled with specimens, the storage device can be detached from the inner tubing and handle of the device and labeled and sent directly to the Pathology lab.

Title: Broad-band quantum well infrared photodetectors
Inventor: GUNAPALA SARATH D
IPC: H01L27/14
Filed: 1998-11-23
Abstract: A quantum well (200) can be designed to detect light of a particular wavelength by tailoring the potential depth and width of the well (202). The design produces two energy states (210, 208) in the well (202) separated by the desired photon energy. The GaAs/Al x Ga~-x As material system allows the quantum well shape to be varied over a range wide enough to enable light detection at wavelengths longer than approximately 6 mm. Hence, large bandgap materials such as GaAs/Al x Ga1-x As material has made fabrication of a large focal plane arrays tuned to detect light at wavelengths from 6 to 25 mm possible.

Abstract: L'invention se rapporte à des méthodes d'isolement de séquences métastatiques ainsi qu'à des séquences isolées. On traite des cellules d'une lignée cellulaire ou un tissu animal de manière à fabriquer une lignée cellulaire prédisposée au cancer. On implante les cellules traitées chez un animal et on les laisse incuber pendant un laps de temps suffisamment long pour que les cellules prolifèrent et développent des transplants malins. On analyse l'ARN du transplant malin et de la tumeur primaire au moyen d'une amplification enzymatique à présentation différentielle. Les gènes exprimés de façon différentielle sont clonés, ré-analysés et séquencés. Il est possible d'utiliser ces gènes et séquences en tant que sondes pour le diagnostic des troubles néoplasiques, en tant que sondes destinées à isoler des séquences métastatiques et en tant qu'agents thérapeutiques pour le traitement des troubles néoplasiques. La séquence métastatique peut être une séquence métastatique dominante ou une séquence métastatique récessive.

Patent CA-2324468-A1 (CA)
Title: Method and system for removal of low order optical transmission modes to improve modal bandwidth in a multimode optical fiber computer network
Inventor: SCHOFIELD BRUCE A
IPC: H04B10/2581
Filed: 1999-05-21
Abstract: A method of improving modal bandwidth in computer networks using multimode optical fiber and single mode sources is disclosed in which the optical signal from a center of the optical fiber is prevented from reaching the detector. This is accomplished according to a number of different techniques including the use of opaque spots on the fiber media/fiber couplers or the use of dark-cored fiber couplers. These configurations prevent pulse splitting that occurs in single mode source/multimode fiber systems by preventing light from the multimode fiber's center from interfering with the detector. When this is achieved, the detector is insulated from the effects of pulse splitting, supporting increased data rates by increasing the modal bandwidth.

Filed: 1999-03-09
Abstract: Cette invention se rapporte à la construction d'instruments d'analyse et peut être utilisée lors de l'analyse d'eaux naturelles ou industrielles, d'échantillons biologiques ou d'échantillons géologiques. Ce procédé de détection d'éléments dans des solutions consiste à pulvériser les échantillons à l'aide d'impulsions, à ioniser les atomes ainsi pulvérisés lors de collisions de Penning, et à enregistrer les ions qui se sont ainsi formés au cours d'une analyse par spectre de masse en effectuant une séparation du temps de vol des ions. La pulvérisation par impulsions de l'échantillon se fait depuis une surface qui est chauffée à une température de 1000 à 1500 ·C et sur laquelle l'échantillon séché dans un flux de gaz de lestage forme un résidu sec. On utilise, en qualité de gaz de lestage, du Kr, du Xe ou des mélanges de ces derniers avec de l'Ar à une pression de 1 à 2 torrs. Le dispositif de détection d'éléments dans des solutions comprend un dispositif d'ionisation qui est disposé dans une chambre à décharge de gaz contenant un gaz inerte. Ce dispositif de détection comprend également un spectromètre de masse à temps de vol qui comprend un système de prélèvement et de focalisation des ions, ainsi qu'une masse réfléchissante consistant en un analyseur spectral. Le dispositif d'ionisation se compose d'une cathode creuse, cylindrique, métallique et à paroi fine, laquelle cathode comprend une ouverture de dosage qui sert à introduire l'échantillon à analyser et qui est disposée sur le même axe qu'un orifice à vide.

Title: Forwarding variable-length packets in a multiport switch
Inventor: AYBAY GUNES
IPC: H04L12/56
Filed: 1999-05-13
Abstract: A method and apparatus for forwarding variable-length packets between channel-specific packet processor (82, 84, 86 and 88) and a crossbar (60) of a multiport switch involve segmenting variable-length packets (150) into fixed-length payload segments and multiplexing the payload segments with response or request data to form fixed-length switching blocks (160). The fixed-length switching blocks are transferred to and from the crossbar over respective input and output connections in order to minimize the number of connections between the packet processors and the crossbar. The input and output connections enable the transfer of a current packet through the crossbar while supplying the crossbar with request information necessary to schedule subsequent packets through the crossbar. In a preferred embodiment of the invention, packets are timed to pass through the crossbar one after another in order to utilize the maximum bandwidth of the crossbar.

Abstract: L'invention concerne un procédé d'augmentation de l'efficacité de la production de para-xylène grâce à une séquence d'isomérisation en deux phases. Dans la première phase du procédé, on soumet une charge d'alimentation de substances aromatiques C¿9??+¿ à une conversion d'éthylbenzène et une isomérisation de xylène. On retire les substances aromatiques autres que C¿8? de l'effluent que l'on traite ensuite dans une deuxième phase du procédé pour éliminer le para-xylène et isomériser l'effluent appauvri en para-xylène. L'effluent provenant de l'unité d'isomérisation de la deuxième phase est ensuite recyclé dans l'orifice d'admission de la deuxième phase du procédé et un filet s'écoulant du séparateur de para-xylène est recyclé dans la charge d'alimentation et dans l'effluent de l'unité de conversion d'éthylbenzène. De cette façon, on maximise la production de para-xylène. Dans un mode de réalisation préféré, on introduit conjointement un toluène dans la charge d'alimentation pour réduire les pertes de xylènes pendant la réaction de conversion d'éthylbenzène.
