Ce procédé est mis en oeuvre avec un dispositif pour projection grand angle qui comporte au moins un projecteur (24) devant l'objectif (28) duquel est placé un miroir (22) comportant une surface réfléchissante (32) sphérique, convexe qui fait face à un écran (20) sensiblement sphérique, concave.
Patent CA-2325706-A1 (CA)
Title: Mechanical strengthening technique for structural elements
Inventor: ABU-ZEID AL-TUHAMI
IPC: E04C5/00
Filed: 2000-11-21
Abstract: In this invention a new technique and apparatus for strengthening the reinforced concrete elements, especially columns, is presented. This technique increases the strength and ductility of the reinforced concrete elements without significantly increasing the dimensions or weights of these elements, or even harming the concrete section. In addition, the technique reduces the lateral strains, internal cracking, and volume increase when adding more loads on the concrete element.      These advantages can be achieved by providing distributed confining pressure along the element length or the required part to be locally strengthened with increasing the reinforcement ratio at the same time. The external applied pressure using the present apparatus can be easily controlled manually or automatically.

Title: Still picture processing for mpeg-2 video
Inventor: NEMIROFF ROBERT S
IPC: H04N7/26
Filed: 2000-12-19
Abstract: Still picture images are encoded and transmitted at reduced rates using the MPEG-2 standard. Video frames are captured for processing at a still picture capture rate that is lower than the video input frame rate. The captured frames are compressed as Intra frames at the input frame rate. Selected ones of the compressed frames are inserted in the MPEG-2 transport stream for communication to a decoder at a still picture repetition rate which is no less, in frames per second, than the capture rate.
Patent CA-2333333-A1 (CA)
Inventor: PRICE RICHARD THOMAS
IPC: H01H9/16
Filed: 2001-01-31
Abstract: A protection and control system incorporates status acquisition apparatus (100) for use in monitoring the status of a device in the protection and control system, such as a protection relay in a high voltage electrical circuit. The status acquisition apparatus comprises an conversion circuit (101) which converts an input voltage to a pulse width modulated signal and a comparison circuit (103) which monitors the pulse width modulated signal to determine the status of the device. The mark-space ratio of the pulse width modulated signal decreases as the input voltage is increased to minimise power dissipation over a range of input voltages. The status acquisition apparatus may form an integral part of a protective switching device, although other applications are envisaged.

Patent CA-2335196-A1 (CA)
Inventor: STIFFLER SCOTT
IPC: B60N2/02
Filed: 1999-06-15
Abstract: The rotary adjustment mechanism adjusts the seat back of a vehicle seat. The  mechanism includes a handle (40) mounted for rotation with respect to the seat. The handle has an internal gear (74), and the internal gear drives a pair of pinion gears (64, 66) positioned within the internal gear. Each gear  rotates a flexible shaft (110, 112), and each shaft connects to a leadscrew (120, 122). The leadscrew has a threaded end, which mates with a threaded nu t (124, 126) connected one seat pivot. Shaft rotation rotates the leadscrew, which causes the threaded nut to move axially, which in turn, pivots the respective seat pivot.
Patent CA-2335782-A1 (CA)
Inventor: LAMBERT SCOTT A
IPC: A61B5/0452
Filed: 1999-06-17
Abstract: L'invention concerne un procédé et un appareil de détecteur d'apnée permettant de surveiller des signaux respiratoires pneumographiques d'impédance et le rythme cardiaque d'un patient. Les intensités de développement de signaux respiratoires sont surveillées afin de décomposer les événements respiratoires en respirations, inhalations et exhalaisons. Un compteur atteignant une valeur de seuil déclenche une alarme si un intervalle de temps sélectionné s'écoule sans qu'un événement respiratoire n'ait été détecté. Si un événement respiratoire est détecté, tel que par la détection de pics successifs, d'un pic ou d'un creux du signal respiratoire, la minuterie se remet à zéro. Le procédé et l'appareil rejettent des artéfacts susceptibles d'apparaître comme des cycles de respiration afin de prévenir de fausses indications négatives d'apnée. Des pics cycliques sont rejetés comme indicateurs d'une respiration s'ils se trouvent dans une plage d'intensités sélectionnée par rapport à celle d'une respiration normale, et s'ils avoisinent le rythme cardiaque du patient. Des pics successifs dus à des soupirs ou relatifs à une modification de ligne de base sont mesurés pour obtenir un taux moyen de modification sur la période pendant laquelle une forme d'onde diminue du deuxième pic selon un niveau sélectionné, lequel correspond généralement à une inhalation ou à une exhalaison normale. Ces pics sont rejetés comme artéfacts si la modification est trop lente. Par conséquent, les soupirs ne sont pas interprétés à tort comme des respirations.

Title: Apparatus and method for application of a film
Inventor: BELANGER EVE
IPC: A21D13/41
Filed: 2001-03-15
Abstract: A method and apparatus for application of a film onto a substrate is disclosed. A stock mixture, for example a proteic stock mixture having 5% to 25% solids, is melted by application of heat to a pre-determined temperature, for example from 65 to 75 °C. Once melted, the stock mixture flows into an incubator where the temperature is maintained until such a time as the stock mixture is sprayed onto a substrate, thereby forming a film on the substrate surface, such as a proteic film. The substrate is not limited to any in particular, but may be a food susceptible to dehydration, such as pizza, quiche, meat, fresh fruit or vegetables.

Title: Systeme et procede pour effectuer une vente aux encheres sur un reseau de communication
Inventor: SNELGROVE WILLIAM MARTIN
IPC: H04M3/56
Filed: 1999-09-24
Abstract: Les procédés permettant de tenir des ventes aux enchères sur Interne et des systèmes téléphoniques sont connus, mais posent généralement les problèmes suivants : il est difficile au commissaire-priseur d'identifier les enchérisseurs ; les conférences téléphoniques sont très bruyantes lorsqu'il y a un grand nombre de participants ; il n'existe pas de méthode pour expulser un enchérisseur qui perturbe la vente ; et il est difficile de faire exécuter le paiement car on ne peut vérifier l'identité et la solvabilité des enchérisseurs. Cette invention propose un système de vente aux enchères où les enchérisseurs sont identifiés au moyen de techniques d'authentification ou autres techniques similaires et où les enchères sont filtrées de façon à réduire le bruit et éliminer les enchères ou commentaires non désirés avant de les communiquer aux surenchérisseurs restants. On peut également ajouter d'autres options telles que l'enregistrement et le marquage de l'heure des enchères.
