Patent CA-2228901-A1 (CA)
Inventor: VAN THONG JEAN-MANUEL
IPC: G10L21/10
Filed: 1998-02-05
Abstract: In a computerized method, speech signals are analyzed using statistical trajectory modeling to produce time aligned acoustic-phonetic units.  There is one acoustic-phonetic unit for each portion of the speech signal determined to be phonetically distinct.  The acoustic-phonetic units are translated to corresponding time aligned image units representative of the acoustic-phonetic units.  An image including the time aligned image units is displayed.  The display of the time aligned image units is synchronized to a replaying of the digitized natural speech signal.

IPC: B05B12/08
Filed: 1998-03-18
Abstract: The   painting   equipment   controller   controls automotive painting equipment so that desired painting attributes can be achieved.   A database  is used for storing mathematical models which interrelate painting factors with painting responses.   The painting factors include the control settings of the painting equipment.          The painting responses include such painting attributes as  the  appearance  of  the  paint  and  application attributes of the paint.   A database engine determines the values  for the painting responses based upon the model  and  upon  initially  selected  painting  factor values.    A  cooptimizer  uses  the  output  of  database engine  to  determine  a  second  set  of  values  for  the painting  factors  which  achieve  the  desired  painting attributes.     Thereupon,  the  painting  equipment  is controlled  based  upon  the  painting  factor  values  as determined by the cooptimizer.

Title: Coating of glass
Inventor: STRICKLER DAVID A
IPC: B05D5/12
Filed: 1997-08-12
Abstract: The invention relates to the coating of flat glass with indium oxide. Indium oxide coatings, optionally doped, for example with tin, are produced in high yield by utilising a chemical vapour deposition process in which a gaseous mixture of an indium precursor compound and a source of oxygen is directed on to the hot glass surface; the indium precursor compound is preferably a dialkylindium compound (which may also be used without pre-mixing but with separate supply of the oxygen source to the glass surface). The processes of the invention are especially suitable for application of a doped indium oxide coating to a continuous ribbon of glass on the production line on which the glass is formed, for use, for example, in architectural glazing applications utilizing the low emissivity of the coating.

Title: Glass fiber facing sheet and method of making same
Inventor: BROWN GORDON L JR
IPC: B65D65/40
Filed: 1998-05-28
Abstract: The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims.  The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim.  The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards.  In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim.  A second facing sheet may also be mechanically integrated into an opposed surface portion of the cement core and contain a melt blown polymer web joined to one face.  The present invention further includes a method of making the glass fiber facing sheet of the invention and a method of making a smooth cement board containing the glass fiber facing sheet of the invention.

Inventor: JANSSON JOHAN
IPC: H03L7/099
Filed: 1996-12-13
Abstract: Cette boucle discrète à verrouillage de phase, ainsi qu'un procédé connexe, permettent la synchronisation globale des communications de données dans des systèmes de communications mobiles. Pour synchroniser l'émission de blocs de données, des horloges de données de blocs et un signal de synchronisation doivent être verrouillés en phase sur un signal global de référence temporelle, ce qui est possible avec une boucle à verrouillage de phase entièrement discrète, réalisée par un circuit ASIC ou par un logiciel, où un automate fini est cadencé par une source, à fréquence fixe élevée et à haute précision, déjà intégrée dans l'équipement radio terminal. Cet automate fini produit les signaux d'horloge de données de blocs et de synchronisation requis, en accomplissant un cycle de compteur. Celui-ci peut, à intervalles réguliers, sauter ou doubler un pas pendant un décompte, afin d'adapter la phase de sortie plus précisément à la phase du signal de référence. Un intervallomètre permet de régler l'intervalle pour lequel cette correction est appliquée, ce qui permet d'imiter un filtre passe-bas elliptique.

Title: Robotics for transporting containers and objects within an automated analytical instrument and service tool for servicing robotics
Inventor: DEYOUNG THOMAS W
IPC: G01N35/04
Filed: 1999-06-07
Abstract: A robotic arm has a pair of gripper fingers designed to grip a variety of containers, including capped and uncapped test tubes as well as containers having unique gripping means. The fingers each have upper and lower projections separated by a groove, the respective projections facing each other when mounted to grippers on the robotic arm. The projections and groove serve to firmly hold the containers as well as self align the unique gripping means on initially unaligned containers within the fingers as the fingers close around the containers. The fingers have clearance to avoid contact with caps on capped test tubes. Stops are provided at the top of each finger to engage one another and prevent fully closed fingers from deforming. The robotic arm may be transported along a rail mounted above the instrument and a gripper assembly, having a gripper arm, mounted to the robotic arm may be rotated above the instrument to move the container to various locations within the instrument. Side posts on the instruments have a gap between them that permits the gripper arm to rotate and extend outwards to interface with an adjacent instrument or a lab automation transport line.

Title: Low monomer polyurethane prepolymer and process therefor
Inventor: KRUEDENSCHEIDT MARKUS
IPC: C08G18/72
Filed: 1997-12-18
Abstract: The invention relates to a monomer-poor polyurethane prepolymer, comprising free NCO groups. Said prepolymer is produced from polyvalent alcohols and diisocyanates having different reactivity and is characterized by the proportion of the NCO groups of the partially less reactive diisocyanate with respect to the NCO groups of the more reactive diisocyanate, the proportion being greater than 6 to 1. However, the inventive prepolymer hardens faster than a known polymer containing primarily more reactive NCO groups. Preferably, TDI is used as partially less reactive diisocyanate and MDI as more reactive diisocyanate. The production of the prepolymers occurs in two stages. The inventive prepolymer is suitable for gluing plastic objects, metals and paper, specially foils, whereby the accelerated migration freedom is quite noticeable.
