Patent CA-2232018-C (CA)
Inventor: GINES DAVID LEE
IPC: H03L5/02

Abstract: Un générateur électrochirurgical possède un système de régulation de puissance de sortie (10) qui fait monter et descendre l'impédance du tissu (14) selon un schéma cyclique jusqu'à ce que le tissu (14) soit desséché. L'avantage du système de régulation de puissance (10) est que la propagation thermique et la carbonisation sont réduites. En outre, le système de régulation de puissance (10) offre de meilleures performances pour assurer le bouchage d'ouvertures dans des vaisseaux et le soudage de tissus par électrochirurgie. La puissance de sortie est appliquée de manière cyclique par un système de contrôle avec rétroaction de l'impédance du tissu. L'impédance du tissu suit le schéma cyclique de la puissance de sortie plusieurs fois, en fonction de l'état du tissu (14), jusqu'à ce que le tissu soit totalement desséché. Une puissance élevée est appliquée pour amener le tissu (14) à atteindre une impédance élevée, et la puissance est ensuite réduite pour permettre à l'impédance de baisser. L'énergie thermique se dissipe au cours du cycle à faible puissance. Le système de régulation est adaptatif au tissu dans le sens que la puissance de sortie est modulée en réponse à l'impédance du tissu.

Patent CA-2244075-C (CA)
Title: Intelligent call redirection
Inventor: COCKRELL JANE E
IPC: H04M3/54
Filed: 1997-12-05
Granted: 2001-08-14
Abstract: An intelligent method is disclosed for handling call redirection to an external service provider (ESP) for subsequent call processing. The method uses a network database (30) that contains information regarding calling/called party stations. The database is accessed to determine if an offering of subsequent call processing should be made and how it should be offered. In an exemplary method of handling call redirection, the database is queried to determine whether the calling party station (5) has pre-selected an ESP for subsequent call processing. In the event that the calling party station has pre-selected an ESP, the call is automatically redirected to the pre-selected ESP; no caller input is required. If, however, the calling party station has not pre-selected an ESP, an announcement is played to the calling party offering a menu of available ESPs. To accept the offer, the caller must explicitly respond to the offer using, e.g., DTMF signalling. The call is then redirected on a per-call basis in accordance with the calling party's selection. In addition to storing a calling station's pre-selected ESP, the database can also be used to store other calling and called party station-specific data regarding subsequent call processing, such as a specific condition for redirection (e.g., the number of rings constituting a ring-no-answer trigger condition) or whether the subsequent call processing should be disabled on calls from the calling party station to the called party station (10).

Abstract: L'invention concerne un procédé et un dispositif qui permettent de détecter une fausse pièce de monnaie en détectant une différence au niveau d'un motif irrégulier gravé à la surface de ladite pièce. On dispose une pièce excitatrice près d'une paroi latérale d'un passage de pièces ayant une inclinaison prédéterminée, de façon que les deux pôles magnétiques de la pièce excitatrice soient tournés vers ledit passage, puis on dispose près de la même paroi deux pièces réceptrices ayant des caractéristiques sensiblement identiques, de façon à produire un couplage électromagnétique avec la pièce excitatrice. On excite celle-ci à une fréquence prédéterminée, de façon à détecter l'influence que la pièce réceptrice exerce sur un champ diamagnétique par l'intermédiaire d'un courant de Foucault produit à la surface de la pièce. A ce niveau, un motif irrégulier différent génère un champ diamagnétique ayant une intensité différente, ce qui permet de détecter une fausse pièce. Le dispositif, de fabrication simple et peu coûteuse, est capable de faire la différence entre des pièces constituées sensiblement du même matériau, ayant sensiblement la même forme et la même épaisseur, sur la base d'une différence dans son motif de surface.

Granted: 2007-09-18
Abstract: A process for the preparation of composition board, particleboard, fiberboard, waferboard and oriented strandboard as well as new and useful products thereof are provided for by the separation of one portion of the solid constituents of the composition board and the separate blending of that portion with adhesive before combining and mixing that portion with the remaining solid constituents of the composition board product. The method and product is particularly adapted to the use of fines as the one portion of the solid component board of composition board and utilizing the pre-coated fines as an adhesive carrier in the final step of mixing or blending of the fines with the remaining composition board components. The novel process and resulting products contemplate the separation of the solid components of the composition board products by particle size so that particles of 10 to 20 mesh, 20 to 40 mesh and 40 mesh and smaller are first separated from the remaining components and then the smallest component is judiciously coated with an adhesive to function as an adhesive carrier when mixed with the remaining solid components of composition board. The novel products of the invention include fines as adhesive nuclei for binding the larger components of the composition board together and produce a more uniform, cohesive and novel composition board product.
