Patent WO-0064623-A1 (WO)
Title: Systeme et procede de traitement de materiaux a l'aide de faisceaux laser multiples
Inventor: KITAI ANTON THEODORE
IPC: B23K26/06
Filed: 2000-04-26
Abstract: L'invention concerne un système d'usinage d'une pièce (PCB, PWB etc.) destiné au perçage de trous borgnes. Ce système comprend un système d'alimentation laser (20, 26, 30) permettant de fournir des faisceaux d'usinage distincts (22a, 22b) séparés l'un de l'autre. Un dispositif déflecteur (28, 32) permet de dévier chacun des faisceaux d'usinage en vue de générer plusieurs faisceaux indépendants en plusieurs emplacements au sein d'un champ d'opération sur ladite pièce. Une lentille de balayage (34) est dotée d'une pupille d'entrée conçue pour recevoir les multiples faisceaux indépendants depuis les éléments déflecteurs, lesquels sont situés près de la pupille d'entrée de ladite lentille. Un ordinateur permet de commander les éléments déflecteurs afin de changer les positions respectives des faisceaux indépendants selon au moins une coordonnée, au sein du champ d'opération. Les élément déflecteurs comprennent des paires galvo/miroirs au niveau de la pupille d'entrée de la lentille de balayage, ce qui est possible en raison de la taille relativement grande de la pupille d'entrée de la lentille de balayage et de la petitesse des parties miroir. Parmi les avantages d'un tel dispositif, tous les faisceaux ont simultanément accès à un champ d'opération plein (généralement 2x2 pouces) sur la pièce, de telle manière qu'on parvient à utiliser le laser avec la meilleure efficacité énergétique.

Title: Panneau coulissant electrique a articulation auxiliaire pour automobile
Inventor: OBERHEIDE G CLARKE
IPC: E05F15/14
Filed: 2001-05-25
Abstract: La présente invention concerne un ensemble (20) fermeture automatisé destiné à une automobile (10). Une liaison latérale est connectée au mécanisme d'entraînement (25) et elle transforme la force de rotation de ce mécanisme d'entraînement en une force linéaire de façon à déplacer la porte entre la position ouverte et une position intermédiaire située entre la position ouverte et la position fermée. Cet ensemble fermeture automatisé comprend aussi une liaison auxiliaire connectée à la liaison latérale et au mécanisme d'entraînement. Cette liaison auxiliaire transforme la force de rotation en une force linéaire de façon à déplacer la porte entre la position intermédiaire et la position ouverte, de sorte que cette porte puisse se déplacer en position ouverte au delà de l'ouverture dans laquelle cette liaison latérale est située.
Patent WO-03012975-A1 (WO)
Title: Commande de gain automatique pour oscillateur commande en tension
Inventor: ROGERS JOHN WILLIAM MITCHELL
IPC: H03B5/12
Filed: 2002-07-30
Abstract: L'invention porte sur une nouvelle topologie de circuit permettant la commande de gain automatique numérique d'un oscillateur commandé en tension. La topologie de l'oscillateur commandé en tension est basée sur l'oscillateur à transconductance négative du fait de sa logique de sollicitation de simplicité intrinsèque. Un paramètre du système sensible au niveau de la performance de l'oscillateur commandé en tension est d'abord mesuré et, en réaction au paramètre du système mesuré, un signal de commande numérique est alors généré. Le courant de sollicitation fourni par le circuit terminal de l'oscillateur commandé en tension est ajusté sur la base de la valeur du signal de commande numérique. De cette manière, le courant de sollicitation de l'oscillateur commandé en tension peut être ajusté par rapport à une valeur optimale de toutes les fréquences de fonctionnement. Les variantes de la commande automatique de cette invention sont utiles dans des implantations monolithiques puisque cela compense automatiquement les variations de la résistance de la charge, les paramètres de traitement et les tolérances de composants sans que cela nécessite des ajustements manuels coûteux au niveau de la carte.

Title: Portable and dynamic distributed applications architecture
Inventor: WHITE JOHN W
IPC: G06F9/44
Filed: 1990-09-12
Abstract: ABSTRACT OF THE DISCLOSURE     A  system  and  method   is  disclosed  for  enabling  a plurality  of computers  and associated  computer resources, some or all of which may  be of heterogeneous configuration, to cooperatively process a variety of applications such that the execution is transparent to the user regardless of where the  application  is  actually  executing.  This distributed applications  architecture  performs  an information distri-bution   service  between  multiple  transaction  processing systems by working with a transaction processor via communi-cation  channels  to  other  hosts  within the network and a dialog  manager  (26)  which  uses  a  transaction processor interface   (78)   to   communicate   with  the  transaction processor.   Additionally,  the  architecture  employs a map service  (36,40) to  provide an  editor to allow application programmers  to  create  the  maps  (40) for the application panels,  a compiler to generate the maps into linkable form, and  a  linkable  interpreter  which translates the linkable form into the screen presentation  format for that platform. Furthermore,  to distribute an  application, the source code for the procedures  (32), views (38) and panels are moved as a block to  the new system.   This is possible  because once the application source code is complete, all of the applica-tion logic, user interface control tables, view definitions, and  other application-specific  tables for  one transaction definition are packaged by the present invention in a single load module on the system where the application will reside. The load  module is then compiled  using the target system's compiler,   link  editor,  and   bind  process.   Thus,  all environment-dependent variations of import/export, including network protocol, operating  systems, processor types, etc., are automatically  integrated with  the application  at load module  bind time.   Therefore, no  source code  changes are necessary.                             TI-13766.1   303
