Title: Arylpyridazinones as prostaglandin endoperoxide h synthase bisoynthesis inhibitors
Inventor: MCCARTY CATHERINE M
IPC: C07D409/06
Filed: 1998-08-10
Abstract: The present invention describes pyridazinone compounds of formula III, which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX/2), COX-2 us the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important "housekeeping" enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marked non-steroidal anti-inflammatory drugs (NSAIDs).

Patent CA-2328227-A1 (CA)
Title: Method of tracking and sensing position of objects
Inventor: POROPAT GEORGE
IPC: G01S5/08
Filed: 1999-04-15
Abstract: A spatial position and orientation sensor based on a three-dimensional imaging system provides information describing the actual three-dimensional spatial position relative to the sensor of objects in the field of view of the sensor. The sensor thus directly determines its location relative to its surroundings. Movement of the sensor, and thus movement of an object carrying the sensor, relative to the surroundings is detected by comparing repeated determinations of the location in three dimensions of fixed features in the surroundings relative to the sensor. An algorithm is used to calculate changes in the position of features in the field of view of the sensor relative to the sensor. Knowledge of changes in position relative to fixed features is used to determine movement in three dimensions of the sensor or an object carrying the sensor relative to the fixed features in the surroundings. The features in the surroundings may be natural or artificial. The true extent of the movement of the sensor in three dimensions is directly determined from the change in position and orientation of the sensor relative to the fixed features in the surroundings. The extent of the movement is used to determine the new position and orientation of the sensor relative to a previous position. When starting from a predetermined location the actual position and orientation of the sensor may be reliably tracked over a period of time by accumulating the measured movements over that time.

Abstract: L'invention concerne un procédé et un appareil d'extraction et/ou de détection non effractive de produits chimiques tels que des métaux lourds, de la drogue telle que de la cocaïne et de matières à analyser telles que la glycémie. On utilise un timbre ou un hydrogel contenant un réactif tel que N-méthyl-pyrrole, ou un composé similaire, pour extraire le produit chimique ou la matière à analyser destinée à être mesurée dans la peau ou les cheveux. Ce procédé est très utile pour détecter des matières à analyser qui sont généralement présentes dans des concentrations sanguines relativement constantes. Le procédé est particulièrement utile pour la détection de métaux lourds tels que le plomb, le lithium, le cuivre, le fer et on a démontré son utilité pour la détection de drogues telles que la cocaïne et l'acétominaphène et de matières métaboliques à analyser telles que la glycémie. Dans le mode de réalisation préféré, le procédé consiste à utiliser le solvant N-méthyl-pyrrolidone (NMP) miscible dans l'eau dans une solution aqueuse qui est incorporée à un tampon adsorbant ou un hydrogel. On place ce tampon adsorbant sur la peau pendant une période définie, puis on le retire et on l'analyse pour trouver la matière intéressante. On peut également intégrer un procédé analytique au tampon adsorbant afin d'effectuer in situ l'extraction du produit chimique intéressant et le dosage. Des exemples illustrent la gamme très large de matières qu'on peut extraire. Des exemples comparatifs démontrent qu'on ne peut pas obtenir les mêmes résultats en utilisant d'autres réactifs tels que le diméthylsulfoxyde (DMSO).
