Patent CA-2226112-A1 (CA)
Title: Method and system for an architecture based analysis of software quality
Inventor: RAUSCHER KARL FREDERICK
IPC: G06F11/28
Filed: 1996-06-25
Abstract: A method and system for providing a software tool that aids the state of the art system engineering of large software systems. The process begins with the step of gathering data (20) on observations of a large number of characteristics about a software system (10), including a historical and planned system adjustments, for each uniquely identifiable software component. Also gathered are historical data regarding faults or problems with each software component. The fault data is statistically mapped (30) to measured characteristics of the software to establish a risk index. The characteristics of the software are predictive of the software's performance or, alternatively, the risk index may be used to rank order the components to determine which components need less testing in an effort to save resources.

Title: Process for production of aromatic tricarboxylic acids
Inventor: GUBSER ANDREAS
IPC: C07C51/265
Filed: 1998-06-02
Abstract: The production of aromatic tricarboxylic acids like trimellitic acid, is enhanced by conducting an improved catalytic liquid phase oxidation of a trimethyl substituted aromatic hydrocarbon, as pseudocumene, continuously in at least three stages of reaction in series. The use as promoter of a ketone or an aldehyde at the first stage of reaction and of bromine at the following stages, in combination with the use of oxygen as oxidizing medium, allows to reduce substantially the global consumption of metal catalysts (Co, Mn, Zr, Ce) and to achieve high values of conversion and of selectivity.

Patent CA-2262587-A1 (CA)
Inventor: SCHAEFER PHILIP
IPC: G01P15/00
Filed: 1998-06-05
Abstract: L'invention concerne un capteur (102) d'angle de rotation comportant un conteneur (104) rempli de fluide, et logeant une ailette (107) immergée dans le fluide (106). L'ailette (107) tourne librement par rapport au conteneur (104). Le conteneur (104) est fixé à un corps dont on veut mesurer l'angle de rotation. Lorsque le corps, et par conséquent le conteneur (104), tourne, le fluide (106), et par conséquent l'ailette (107), tend à demeurer fixe par rapport à la rotation. On peut donc mesurer l'angle de rotation en déterminant l'ampleur du mouvement de rotation effectué par le conteneur (104) par rapport à l'ailette (107).
Patent CA-2263283-A1 (CA)
Inventor: BECK JON E
IPC: A61N1/30
Filed: 1998-03-11
Abstract: La présente invention se rapporte à des procédés et à un appareil permettant le maintien en isolement d'au moins un liquide d'hydratation et, lorsque nécessaire, la libération totale du liquide d'hydratation. Ledit système autonome d'hydratation comporte un organe de scellement libérable conçu pour isoler le liquide d'hydratation (3) et susceptible d'être retiré progressivement de manière à libérer le liquide d'hydratation. Le processus de retrait de l'organe de scellement implique un arrachage de l'organe de scellement libérable formé entre une bande (28) et une barquette (22), et ne nécessite ni cassure ni rupture du matériau de scellement. De cette manière, le liquide d'hydratation est rendu accessible sans jamais être exposé à des débris de cassure ou de rupture du matériau de scellement. Ce système d'hydratation autonome peut être fabriqué au moyen d'équipements existants et selon des techniques connues, et il peut être facilement associé ultérieurement à un dispositif distinct nécessitant une hydratation à la demande.
Patent CA-2263538-A1 (CA)
Title: Nuclear quadrupole resonance testing
Inventor: PEIRSON NEIL FRANCIS
IPC: G01R33/46
Filed: 1997-08-28
Abstract: Methods of testing a sample in which long composite pulses comprising a sequence of short closely spaced pulse elements are disclosed. The pulses generate a qualitatively different response characteristic, which can be tailored as desired by suitable adjustment of the pulses. Near sinusoidal dependence on pulse length can be attained, and effective, efficient, inversion pulses can be produced. Typically each pulse element generates a small flip angle of a few degrees, and the sequence contains tens or even hundreds of elements. Similar excitation and effects may be produced by amplitude modulating a carrier, rather than switching pulses on and off; there is little discernible difference in the excitation seen by the sample.

Patent CA-2272594-A1 (CA)
Title: Method and apparatus for improving performance of a packet communications system
Inventor: TURINA DALIBOR
IPC: H04L12/28
Filed: 1997-11-27
Abstract: A communications system (10) is provided that uses a multiple access packet reservation type of protocol. The physical channels required for the packet transfers are specially allocated to one mobile station (16) (referred to as a "VIP MS"). The VIP MS (16) has the exclusive priority to use these allocated physical channels for packet data as needed. Consequently, the VIP MS (16) always has the negotiated bandwidth available for the packet transfers. Furthermore, since the VIP MS (16) is given the highest exclusive priority to access these physical channels ("VIP priority"), by allocating a reserved random access channel dedicated to the VIP MS (e.g., on one allocated uplink channel), the variable random access delays experienced by prior systems no longer exist. Since the VIP MS (16) is always scheduled first for transmissions on the downlink, and reserved access is provided for the VIP MS (16) on the uplink, only a constant delay period for the uplink and downlink is involved. In other words, the VIP MS  (16) is guaranteed both a bandwidth for the packet transfers and a constant uplink and downlink delay.
