Patent CA-2388539-A1 (CA)
Inventor: ARSENAULT CATHLEEN M
IPC: B67D3/04
Filed: 2000-02-04
Abstract: La présente invention concerne un embout de clapet de distribution pouvant être monté sur une bouteille, doté d'un premier élément de clapet présentant une partie tubulaire comprenant une entrée d'air, le premier élément de clapet présentant également une sortie de liquide espacée le long d'un axe longitudinal de la partie tubulaire pour former un clapet à charge constante permettant de distribuer le liquide de la bouteille. Un second élément de clapet monté mobile sur le premier élément de clapet comprend une partie tubulaire permettant de fermer simultanément l'entrée d'air et la sortie de liquide du premier élément de clapet lorsque la distribution de liquide n'est pas souhaitée. Le second élément de clapet comprend également une entrée d'air pouvant s'aligner avec l'entrée d'air de la partie tubulaire lorsque la distribution de liquide est souhaitée. L'embout de clapet de distribution commande le flux de liquide venant de la bouteille. La bouteille dotée de l'embout de clapet peut être utilisée avec un système de distribution permettant de mélanger un liquide concentré venant de la bouteille avec un diluant. Un élément de verrouillage inviolable permet d'empêcher la rotation non désirée du second élément de clapet par rapport au premier élément de clapet. L'élément de verrouillage inviolable est désactivé lorsque l'embout de clapet est inséré dans le système de distribution.

Title: System and method for electronic storage and retrieval of authenticated original documents
Inventor: BISBEE STEPHEN F
IPC: G06Q20/00
Filed: 2000-12-01
Abstract: Digital signatures are not valid indefinitely but only during the validity periods of their authentication certificates. This poses a problem for electronic information objects that are intended to have legal weight for periods longer than the remaining validity period of a signature. There are thus provided methods of handling stored electronic original objects that have been created by signing information objects by respective transfer agents, submitting signed information objects to a trusted custodial utility, and applying to each validated information object a date-time stamp and a digital signature and authentication certificate of the trusted custodial utility. One method includes re-validating an electronic original object by verifying the digital signature of the trusted custodial utility applied to the object and applying to the re-validated object a current date-time stamp and a digital signature and current authentication certificate of the trusted custodial utility. Another method includes creating an object-inventory from at least one stored original object, including an object identifier and a signature block for each object. A time stamp and a signature and certificate of the trusted custodial utility is applied to the object-inventory. Other methods involve handling information objects that are transferable records according to specified business rules, which avoids that copies of the transferable records can be mistaken for originals.

Title: Minimizing adverse experience associated with oxybutynin therapy
Inventor: SANDERS STEVEN W
IPC: A61K9/16
Filed: 2001-04-24
Abstract: The present invention provides compositions and methods for administering oxybutynin while minimizing the in-cidence and or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as N-desethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy.

Patent CA-2406503-A1 (CA)
Inventor: LARSON BRENT D
IPC: G02F1/1335
Filed: 2001-04-12
Abstract: An apparatus and method for improving the brightness of a polarized display (200) at viewing angles off of the vector normal to the display panel (202).  The advantages of the present invention will be most pronounced when employed in applications in which the viewing angle requirements are asymmetric, such as for avionics applications that require cross-cockpit viewability of the display. The present invention overcomes the limitations inherent in earlier designs by introducing a polarization rotation element (230) as part of the display device to rotate the polarization of light from one orientation (232) to another orientation (236). Through the use of the present invention, the axis in which the angle of sufficient off normal brightness is broadest can be reoriented to an axis (212, 222) that is most ideal for the particular application, thus dramatically improving the overall performance and efficiency of such displays.
