Patent CA-2382475-A1 (CA)
Title: Liquefracture handpiece tip
Inventor: SUSSMAN GLENN
IPC: A61M1/00
Filed: 2000-09-12
Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The distal end of the annular gap is sealed by sealing together the distal ends of the first and second tube and a plurality of orifices or ports may be formed near the seal. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifices in a controlled and directed manner. The distal end of the first and second tubes may contain a bend.

Abstract: Die inserts and methods for use in high-pressure hot-chamber diecasting are disclosed which substantially eliminate sprue castings and greatly improve melt flow. The die inserts comprise (i) a heated sprue body insert (130, 258) adapted for location in the fixed dieblock (112) of a die set and having a sprue channel (136, 260) and (ii) a cooled sprue tip insert (132, 266) adapted mounting in the moving dieblock (114) of the die set. The sprue body and tip inserts are mounted coaxially so that their inner ends mate with one another in the region of the die parting-line (155) to conjointly form at least one curved transition channel (138, 262, 264) that connects the sprue channel (136, 260) with at least one runner channel (140, 254, 256) formed along the parting-line. The temperatures of the sprue body insert and the sprue tip insert are controlled so that the freeze-point occurs in the transition channel and the melt in the sprue channel is able to run back into the machine nozzle at the end each shot, thereby eliminating sprue castings.
Patent CA-2386148-A1 (CA)
Inventor: KELLY KEITH
IPC: G06Q40/02
Filed: 2000-10-02
Abstract: Cette invention concerne un procédé et un système informatique(100) permettant de réduire le taux d'intérêt appliqué à un créancier hypothécaire lorsque le taux hypothécaire en vigueur change. L'utilisation d'une hypothèque à réduction automatique de taux (ARC) permet d'abaisser le taux d'intérêt appliqué à un client sans devoir passer par le processus traditionnel de refinancement. Le prêt ARC constitue un modèle de financement tant pour l'achat que le refinancement d'un bien (une résidence par exemple). Lorsque le client est resté suffisamment longtemps dans le programme après la date de règlement, il est possible de revoir le taux d'intérêt à la baisse sous réserve que les taux d'intérêt aient baissé depuis la date de souscription du prêt ARC par le client. On peut également faire intervenir des conditions secondaires pour déterminer si une baisse du taux hypothécaire se justifie.

Patent CA-2388040-A1 (CA)
Inventor: MENG TERESA H
IPC: H04B1/707
Filed: 2000-10-17
Abstract: L'invention concerne un appareil et un procédé qui permettent de détecter l'heure d'arrivée relative, à un récepteur simple, de différents signaux provenant de différents émetteurs-récepteurs respectifs, et d'amener ces derniers à modifier l'heure à laquelle ils transmettent leurs signaux afin que l'heure d'arrivée desdits signaux se situe dans un intervalle de temps préétabli. Le procédé de l'invention met en oeuvre soit un synchronisateur en boucle fermée, soit un synchronisateur GPS, soit encore un synchronisateur en boucle ouverte, pour déterminer l'heure à laquelle des signaux provenant de différents émetteurs-récepteurs doivent être modifiés pour déterminer l'heure d'arrivée pour différents signaux dans les limites dudit intervalle de temps préétabli. Il résulte du caractère "semi-synchrone" des signaux entrants que les algorithmes de détection exploitant le synchronisme temporel, tel qu'une détection multi-usager ou un rejet des bruits, peuvent être beaucoup plus efficaces en détection de signaux pour les données transmises à un récepteur simple à partir de plusieurs émetteurs-récepteurs.

Title: A method and system for dynamically allocating a frame buffer for efficient anti-aliasing
Inventor: DAWSON THOMAS PATRICK
IPC: G06T15/40
Filed: 2001-11-09
Abstract: An anti-aliasing system provides anti-aliasing at the edges of objects in a displayed or printed image without video artifacts or the need for an expensive anti-aliasing buffer. As geometric data is rasterized, the rasterizer (102) identifies pixels on the edge of objects in the image being  rendered. These pixels are then rendered at a higher resolution with a numbe r if sub-pixels. The Z-buffer (109) is signaled as to which pixels will requir e the additional, higher resolution data. The Z-buffer (109) then dynamically allocates memory space in an additional memory unit (110) to hold that additional sub-pixel data. A memory offset or address is provided in the Z- buffer to direct the memory controller (115) to the appropriate address in t he additional memory unit (110) when the data in the additional memory unit is being blended to produce the data defining the corresponding main pixel whic h data is then stored in the Z-buffer (109).

Title: Electromigration early failure distribution in submicron interconnects
Inventor: HO PAUL S
IPC: G01R31/28
Filed: 2001-04-17
Abstract: A test structure and a method for detecting early failures in a large ensemble of semiconductor elements, particularly applicable to on-chip interconnects, is provided. A novel approach to gain information about the statistical behavior of several thousand interconnects and to investigate possible deviations from perfect lognormal statistics is presented. A test structure having a Wheatstone Bridge arrangement and arrays of several hundred interconnects may be used to prove that failure data does not deviate from lognormal behavior down to a cumulative failure rate of approximately one out of 20,000. Typical test structure sizes may, therefore, be extended far beyond standard test procedures to gain information about the statistical behavior of failure mechanisms and to verify the validity of the assumption that failure mechanisms follow lognormal statistical behavior.

Filed: 2001-07-02
Abstract: L'invention concerne une méthode et des compositions destinées à la détection sensible de la quantité et de l'emplacement de séquences d'acides nucléiques spécifiques. Ce procédé fait intervenir un oligomère ramifié, appelé oligomère lollipop, comprenant une partie caudale, une partie de bras droit et une partie de bras gauche. Ces trois constituants se rejoignent au niveau d'une jonction commune formant une structure à trois queues. Les deux bras se terminent chacun par des séquences complémentaires aux séquences adjacentes dans une séquence cible. Cela permet aux bras droit et gauche d'être ligaturés ensemble lorsque l'oligomère est hybridé à la séquence cible, d'où la liaison topologique de l'oligomère à la séquence cible. La partie caudale peut alors être détectée à l'emplacement de la séquence cible.

Title: Packet routing
Inventor: TATESON JANE ELIZABETH
IPC: H04L45/24
Filed: 2001-07-05
Abstract: The present invention provides a routing protocol that scatters a stream of packets along a number of parallel paths, the packets being treated independently. The next hop for each packet is chosen probabilistically by comparing the resistance of available options. The resistance of a given hop depends upon the time the packet would spend in an output buffer from the current node, the time the packet would spend in the input buffer of the next hop node, the transfer time between the nodes 0 and the number of hops that the packet would take from the current node to the ultimate destination of the packet using the shortest path. This routing protocol is more efficient that shortest path first routing under simulation.
