Patent CA-2233379-A1 (CA)
Inventor: PATEMAN THOMAS J
IPC: E01F9/627
Filed: 1998-03-26
Abstract: Apparatus is provided for self-righting a signpost after it has been tipped over comprising a plate for connecting to the signpost and a complementary tray secured to the ground. Most of the apparatus is located below ground out of harm's way. The tray has upturned peripheral edges within which the plate resides. A chain is connected to the plate, extends through a hole in the tray and into the bore of a pipe for connecting to the bottom of a compression spring. When the signpost and plate tip, the plate rotates within the tray, displacing the chain and compressing the spring. Preferably a lip extending over the edge of the plate causes the plate to ride up the edge of the tray, increasing the chain's displacement. The increased tension in the chain urges the plate and signpost to right themselves. The plate and tray are complementary and square shape so that the square sides engage during tipping and prevent rotation of the signpost's orientation when it returns to the upright position. Preferably a cup is mounted to the plate for insertion of the shaft of a conventional signpost.

Patent CA-2240683-A1 (CA)
Title: Spread spectrum mri
Inventor: CROWLEY CHRISTOPHER W
IPC: G01R33/46
Filed: 1998-07-09
Abstract: A method for acquiring data from voxels in a contour of tissue includes positioning the tissue in a magnetic field. For the present method, a z-gradient is imposed on the contour tissue to spread the spectrum of all of thevoxels over a same range of Larmor frequencies. Additionally, voxels in the contour tissue are selectively encoded with different x-gradients and y-gradients to distinguish the various voxels from each other. In the presence of the z-gradient, nuclei of the encoded voxel are tilted and then refocused at a rate proportional to the z-gradient. Due to this refocusing, spin echo signals are generated which are useful for acquiring data from the tissue. The intravoxel z-gradient used for the present invention is the same for all voxels and is greater than either the x-gradient or the y-gradient which are used for encoding. The z-gradient may be substantially constant. Importantly, the z-gradient is sufficiently extensive to spread the spectrum of the spin echo signals for suppression of exogenous noise and make the signals immune to static field perturbations.

IPC: A61L33/00
Filed: 1997-03-07
Abstract: La présente invention décrit une technique de modification par covalence de surfaces tissulaires et cellulaires permettant d'inhiber l'adhésion cellulaire. Le procédé décrit dans le présent contexte s'effectue dans des conditions tolérables in vivo et emploie un polymère biocompatible ayant un groupe réactif attaché à au moins une extrémité et qui réagit avec des groupes présents dans ou sur des surfaces tissulaires et cellulaires dans des conditions aqueuses douces et, de ce fait, attache le polymère par covalence à la surface tissulaire ou cellulaire. De manière préférentielle, le groupe réactif attaché au polymère réagit avec des amines et des hydroxyles présents sur les surfaces tissulaires et cellulaires. Dans une réalisation préférée, les procédés décrits dans le présent contexte fournissent une modification covalente des surfaces tissulaires et cellulaires utilisant une solution PEG-diisocyanate. Les procédés décrits ici sont particulièrement utiles en cas de dépôt dommageable de plaquettes et de leucocytes dans les vaisseaux sanguins lors de thromboses et de resténoses récalcitrantes, complication courante lors des procédures vasculaires comprenant l'ACTP et la chirurgie vasculaire. En outre, en masquant les protéines de surface tissulaire des éléments sanguins, les procédés décrits dans le présent contexte sont utiles car ils diminuent la thrombogénicité de la greffe et réduisent les complications de chirurgie vasculaire. Enfin, les procédés décrits ici réduisent les capacités immunogènes des cellules et tissus transplantés et, de ce fait, réduisent le besoin d'une thérapie immunodépressive.

Title: Method for determining the orbital positions of satellites in leo networks
Inventor: KELLERMEIER JOHANN
IPC: H04B10/118
Filed: 1998-12-17
Abstract: In order to achieve a considerable reduction of the outlay required on the ground in connection with the accurate calculation of the exact orbital position of each individual satellite of a constellation, first the exact orbital position of a preferably central master satellite of a sub-group of satellites embodied as a special formation is determined. This calculation is performed autonomously on board the satellite by means of customary measurements supported from the ground, or respectively by means of GPS, MANS, etc. Then the exact position of all other satellites in the same formation is determined from range and pointing data, which are provided by each IS link terminal.  These pointing data are well known after the establishment of the inter- satellite link and are continuously updated.
Patent CA-2255390-A1 (CA)
Title: Optical disc device
Inventor: NOMURA MASARU
IPC: G11B19/20
Filed: 1998-12-09
Abstract: A controller instructs a spindle motor to start rotating, and instructs a servo control section to start a focus servo control.  When a light beam crosses information tracks on an optical disc with a rotation of the optical disc, an amplitude indicating signal generating section detects changes in the amplitude of a readout signal output from an optical pickup.  A disc type identifying section identifies types of optical discs having different track pitches of the information tracks in starting the rotation of each optical disc based on the peak value and bottom value or the amplitude of the readout signal.  Consequently, the types of optical discs having different information recording densities, particularly different track pitches, can be identified at an early stage without waiting for reproduction of information recorded on each optical disc.  It is therefore possible to shorten the time for starting an optical disc device, or prevent an increase in the starting time.
Patent CA-2261809-A1 (CA)
Inventor: SEGER GEOFFREY EUGENE
IPC: A61F13/534
Filed: 1997-07-22
Abstract: The fluid absorbent members according to the present invention preferably comprise three basic components: chemically stiffened, twisted, and curled bulking fibers, high surface area fibers, and a binder additive such as thermoplastic fibrous material or chemical binders. Fluid absorbent members according to the present invention use a high surface fiber and refining to provide capillary pressure (or suction) to the fluid absorbent member. These high surface area fibers are generally small and highly conformable. They provide the substrate with capillary pressure well in excess of the capillary pressure found in the bulk-providing chemically stiffened, twisted, and curled fibers (unrefined) alone. A presently preferred fiber for this high surface application is the eucalyptus family of wood pulp fibers. Eucalyptus provides desirable capillary pressure characteristics in combination with the chemically stiffened, twisted, and curled fibers and will not easily pass through a forming screen. In accordance with the present invention, these component materials are combined into a stratified, multi-functional fluid absorbent member wherein the strata are preferably co-formed. The present invention therefore provides structures wherein the properties of the strata may be tailored to suit particular applications by utilizing the different compositions of the strata to achieve specific functionality.

Title: Bloc de beton ouvert
Inventor: MORISSET PIERRE
IPC: E04B2/02
Filed: 1999-03-05
Abstract: Les blocs de béton ouverts proposés ici servent à construire des murs porteurs aussi bien que des murs de parement. Ces blocs s'inscrivent dans un parallépipède rectangle et comprennent un dessus, un dessous, et quatre côtés dont deux petits. Au moins trois des quatre côtés, soit au moins un grand et deux petits, comportent une partie creuse ouverte en forme de "U" dont les parois sont verticales, constituant trois ou quatre demi-alvéoles, ou alvéoles ouvertes, qui possèdent plusieurs avantages. Les alvéoles verticales ouvertes des petits cotés se posent contre les alvéoles ouvertes semblables des blocs voisins pour former des alvéoles fermées permettant la mise en place d'un coulis armé ou non, qui assure la solidité mécanique des murs, et l'étanchéité aux intempéries des joints verticaux, éliminant la nécessité des joints de mortier verticaux traditionnels, erratiques et coûteux. Dans certaines conditions, les joints de mortier horizontaux traditionnels peuvent être aussi éliminés, permettant la mise en place à sec des blocs par une main d'oeuvre moins experte, et facilitant la construction hivernale. Par ailleurs, une alvéole verticale ouverte (ou demi-alvéole) d'un grand côté permet d'enfoncer au creux du mur divers éléments de construction, à la manière des systémes à ossature de bois: Les isolants thermiques et phoniques, le bout des solives de plancher, et les éléments de mécanique du bâtiment. Ce bloc ouvert, qui peut aussi étre posé avec joints de mortier traditionnels, est remarquable par sa polyvalence, ses avantages économiques directs et indirects, ses retombées positives sur la qualité de la construction, et il est apte à supplanter les blocs de béton existants qui constituent le matériau de construction murale dominant dans le monde.

Abstract: A multi-kernel neural network computing architecture configured to learn correlations among feature values (34, 38) as the network monitors and imputes measured input values (30) and also predicts future output values (46). This computing architecture, referred to as a concurrent-learning information processor (CIP 10), includes a multi-kernel neural network array (14) with the capability to learn and predict in real time. The CIP (10) also includes a manager (16) and an input-output transducer (12) that may be used for input-output refinement.      These components allow the computing capacity of the multi-kernel array (14) to be re-assigned in response to measured performance or other factors. The output feature values (46) computed by the multi-kernel array (14) and processed by an output processor (44) of the transducer (12) are supplied to a response unit (18) that may be configured to perform a variety of monitoring, forecasting, and control operations in response to the computed output values. Important characteristics of the CIP (10), such as feature function specifications (35 and 49), connection specifications (42), learning weight schedules (55), and the like may be set by a technician through a graphical user interface (20). Refinement processes also allow the CIP (10) to be reconfigured in accordance with user commands for application to different physical applications.
