Patent WO-0106796-A1 (WO)
Title: Systeme de projection d'images
Inventor: GIBBON MICHAEL A
IPC: H04N9/31
Filed: 2000-07-06
Abstract: L'invention concerne un projecteur électronique possédant un système de projection comprenant un modulateur spatial de lumière (SLM) servant à répercuter les informations de l'image sur le faisceau lumineux projeté. Le faisceau lumineux quittant ledit modulateur est préalablement polarisé selon une orientation définie, la lumière projetée étant polarisée selon la même orientation de manière à bloquer efficacement toute la lumière qui a été diffusée au sein du projecteur et qui a été dépolarisée. Le modulateur peut être un miroir numérique (DMD) ou un dispositif à cristaux liquides (LCD). Les surfaces réfléchissantes dans le projecteur peuvent être recouvertes ou revêtues d'un matériau polarisant la lumière réfléchie avec une orientation orthogonale par rapport à l'orientation définie.

Title: Comptage differencie dans un reseau de paquets de donnees
Inventor: MADOUR LILA
IPC: H04M15/08
Filed: 2003-07-21
Abstract: L'invention concerne un procédé, un système et un noeud d'accès à des paquets de données (PDAN), par exemple un noeud de service de paquets de données (PDSN) d'un réseau CDMA2000, permettant d'effectuer un comptage basé non seulement sur l'adresse IP d'un terminal associé au PDAN (par exemple une station mobile), mais aussi sur des informations associées à un noeud correspondant (CN) avec lequel communique le terminal au cours d'une session de paquets de données, par exemple l'adresse IP du noeud correspondant (CN) et, éventuellement, le numéro de port/ID de l'application CN, et la qualité de service (QoS) pour cette session. La session est établie entre le terminal et le CN à l'aide d'une signalisation de protocole d'initialisation de session (SIP), et le PDAN reçoit des informations associées au CN d'une fonction de commande de commutation d'appel proxy (P-CSCF). Le PDAN compte le trafic associé au CN et transmet le résultat, ainsi que les informations du CN, à un serveur d'autorisation, d'authentification et de comptage (AAA). Le comptage peut alors être effectué à partir des informations associées au CN.

Title: Solid state differential pressure sensor with overpressure stop and free edge construction
Inventor: KNECHT THOMAS A
IPC: G01L13/06
Filed: 1989-10-19
Abstract: SOLID STATE DIFFERENTIAL PRESSURE SENSOR            WITH OVERPRESSURE STOP AND FREE                   EDGE CONSTRUCTION              ABSTRACT OF THE DISCLOSURE      A solid state pressure sensor utilizes a brittle diaphragm made of a material such as silicon, which is mounted between base plates of glass, and which deflects in response to pressure. The base plates of glass can have recesses formed therein to receive the diaphragm and provide a full support across the diaphragm under overpressure conditions to prevent overstressing the diaphragm,  or the diaphragm can have such contoured surfaces for forming overpressure stop surfaces against the facing base plate.   The diaphragm has grooves defining a central portion that deflects, and whereby the grooves will form webs joining the central portion to an outer rim so that the diaphragm acts similarly to a   "free   edge"   diaphragm   in   its   deflection characteristics.  The grooves defining the webs can have various configurations for achieving the results desired.

Inventor: WENKE GERHARD
IPC: B64D47/00
Filed: 1990-03-05
Abstract: ABSTRACT OF THE DISCLOSURE          A  heat  conducting  interface  unit  for  use  in mounting  an  electronic  module  between  cooling  plates, includes  an  elongated  flexible,  U-shaped,  highly  heat conductive  metallic  heat  exchange  member  adapted  to receive a condensor end of the electronic module.   The heat exchange member is located within a housing which provides liquid coolant chambers on the outside walls of the heat exchange member. The coolant is supplied under pressure through inlets in the housing from corresponding ports in the cooling plates.  The pressure in the coolant chamber urges the flexible metallic heat exchange member into  increased  contact  pressure  with  the  condensor portion of the  electronic module,  reducing the thermal resistance across the contact interface,  increasing the rate of heat transfer to the cold plate, and clamping the module in position.  The heat exchange member covers the entire  surface  of  the  condensor  to  maximize  heat transfer.  It also provides  a  simple  structure and  a short thermal path to the coolant.

Patent CA-2017008-A1 (CA)
IPC: B66F3/02
Filed: 1990-05-17
Abstract: A device with one or more actuator racks carried by a housing for reciprocation and each meshing with a separate pinion gear having a non-circular central hole in which a complimentary coupling shaft can be removably received for rotation in unison with the gear(s).   The pinion gears are carried and journalled for rotation in the housing by a pair of co-axial bushings with generally opposed and spaced apart axially projecting rims received in mating peripheral shoulders in the side faces of the gears. The gear teeth extend generally axially continuously between their side faces with the shoulders in their side edges.  Preferably the radial extent of each shoulder is less than the radial extent of the teeth.  When the coupling shaft  is  removed  from  the  gears  each  pinion  can  rotate independently of the shaft and each other to initially position its associated rack at a desired location and when the shaft is  inserted in the pinion gears  they rotate  in unison to simultaneously actuate the rack(s).
