Patent CA-2360465-A1 (CA)
Inventor: BOYLE JOHN W
IPC: A61F2/30
Filed: 2000-01-24
Abstract: An intervertebral implant having a composite wedge/dowel configuration is provided. The intervertebral implant includes a central body portion and a pair of radially extending wings. The radially extending wings can be tapered from a first end of the implant to the second end of the implant along an axis parallel to the longitudinal axis of the central body portion. Alternately, the radially extending wings can be tapered along an axis transverse to the longitudinal axis of the cylindrical body portion or along any other axis between parallel and transverse to the longitudinal axis. A throughbore or plurality of throughbores extend from a top surface of the implant through the implant to a bottom surface of the implant. The implant may be formed from a cortical ring cut from the diaphysis of a long bone by milling the top and bottom surfaces of the cortical ring to form the substantially central body portion and the tapered radially extending wings. The cortical ring is milled such that the intramedullary canal of the cortical ring defines a throughbore in the central body portion of the implant. The sidewalls of the implant may be machined to form a substantially rectangular shape or the implant can be left to have a substantially circular configuration. Alternately, the implant may be formed of any biocompatible material having the requisite strength requirements via any known process, i.e., molding.

Patent CA-2372596-A1 (CA)
Inventor: RADICHIO ARTHUR
IPC: F25D15/00
Filed: 2000-05-02
Abstract: A pipe freezing apparatus comprises a multi-cavity adapter (20) and an evaporator (36) adapted to be fitted therein. The present invention uses a multi-cavity adapter having from two to eight cavities (42-48) to fit standard plumbing pipes in copper, steel and plastic, metric and US standard. The refrigeration evaporator fits into a cylindrical bore (36) in the core of the radial multi-cavity array. The cavities are arrayed around the circumference of the bore. The adapter body that forms the array is of aluminum or the like. The coolant lines (132, 134) are elbowed at 90 degrees to the evaporator's longitudinal axis to facilitate attachment to the pipe in small or tight spaces and from the side of the pipe. The adapter body freely swivels around the evaporator thus reducing wear on the refrigeration tubes as the adapters are mounted on the section of pipe to be frozen. Thus any of the cavities can be lined up with the pipe. A set of special retainer mechanisms (90, 92) is used to tightly secure the adapter bodies to the section of pipe to be frozen, thus providing for close thermal contact.

Title: Relation path viability prediction
Inventor: AGASSI SHAI
IPC: G06F17/30
Filed: 2000-06-29
Abstract: There is provided a process for predicting whether a query will produce a result (514) in an information system formed of objects hav-ing different instances and relations between the objects. An instance-to-ob-ject bitmap (512) is computed off-line, before queries are generated by a user: the bitmap is used to represent the existence of a relation path from instances to the other objects of a database. When a query is generated, the bitmap is accessed to predict whether there exists a relation from the instance to the object, that is whether the query will issue a result. The process makes it possible for a user to abort queries (518) without consuming run-time. It also makes it possible to guide users through navigation of a WebPages or the like, by suggesting relations that will produce results.

Abstract: Le premier processus fournit un éditeur dépendant du contexte de façon à créer, modifier et afficher des informations de contrôle hiérarchiquement structurées. Cet éditeur permet de choisir des actions adaptées au contexte immédiatement en cours, simplifiant ainsi le protocole de manipulation de l'utilisateur. Du fait que l'éditeur comprend la relation entre les contextes et le caractère multiple de ces derniers, son éditeur et son affichage représentent la répétition et la conditionnalité des blocks sans recourir à un langage d'information en code machine. Cet éditeur affiche les informations de contrôle conformément aux règles d'affichage du contexte associé. La présentation établit une différence claire entre le texte en soi, la structure dans laquelle est placé ce texte, et les éléments paramètres. L'éditeur traite efficacement ce qui relève des méta-informations de contrôle d'une manière qui permet de les afficher sous forme d'informations. Le second processus concerne un procédé permettant de transformer systématiquement les informations de contrôle en format machine, tel que des données machine génératrices de code.

Title: Playback of interactive programs
Inventor: PIERRE LUDOVIC

Filed: 2000-09-15
Abstract: A method for playing back a program which includes one or more interactive applications. A program which is stored, either in the form of a data stream or as a set of files is played back from a storage device. When playback is started, applications which are detected are launched. Applications are detected in the playback of pushed content when they become available in the playback stream. Applications are detected in the playback of pulled content by comparing the validity ranges of the applications to a current playback index. When special playback modes are used, signals which affect the lifecycle of an application are detected and corresponding signals are generated to maintain the proper state of the application. During these special playback modes, these various notification signals may be conveyed to applications which are configured to operate during these modes. Applications which are not configured to operate during these special playback modes may be terminated when the special modes are initiated and restarted when the special modes end.

Inventor: WOODSIDE SHANE H
IPC: G01M11/00
Filed: 2002-06-28
Abstract: A system and method for resolving polarization mode dispersion (PMD) in a span of optical fiber is described. The method involves three main stages: (1) launch two co-polarized optical signals to generate respective four-wave mixing product fields at the Stokes wavelength .lambda.s or the anti-Stokes wavelength .lambda.A sequentially in each part of the fiber to calculate chromatic dispersion; (2) repeatedly launch two optical signals at various states of polarization (SOP) using methods of stage (1) to calculate overall dispersion (i.e., a combination of chromatic dispersion and PMD); and (3) resolve from the overall dispersion calculated at stage (2) the PMD based on the known chromatic dispersion calculated at stage (1). In an ideal case, the PMD can be calculated from two separate measurements at different co-polarized states of polarization, where group velocity is calculated from a measured dispersion map, as a function of wavelength, at the SOPS and the difference is calculated to resolve PMD.
