Patent CA-2353827-A1 (CA)
Inventor: DOLPHIN DAVID
IPC: G01N27/447
Filed: 1999-12-10
Abstract: A method for the separation of isomers and stereoisomers of photosensitizers by Laser-Induced Fluorescence Capillary Electrophoresis has been developed. The limits of detection are 2.06 x 10-6 M, and the relative standard deviation for the separation was 2.90 % to 4.64 %. Benzoporphyrin derivative mono and diacid (BPD-MA, BPD-DA) enantiomers can be quantitatively determined in the range of 10-2 to 10-5 mg mL-1. In comparison with HPLC, CE has better resolution and efficiency. This separation method was successfully applied to the BPD enantiomers obtained from a matrix of bovine serum and from liposomally formulated material as well as from studies with rat, dog and human microsomes.

Title: Voip gateway device and digital one-link tandem exchange method
Inventor: MIZUSAWA TSUNETOSHI
IPC: H04L12/70
Filed: 2001-09-24
Abstract: A VoIP (Voice over IP network) gateway device includes an identification pattern inserting section, identification pattern detecting section, pass through frame assembly section, and pass through frame processing section. The identification pattern inserting section inserts an identification pattern of a predetermined bit pattern in a receiving signal from an IP transit trunk, and sends out the signal to a digital exchange. The identification pattern detecting section detects an identification pattern from a receiving signal from the digital exchange. The pass through frame assembly section converts an RTP (Real-time Transport Protocol) packet obtained from the IP transit trunk into a digital voice signal in a pass through frame format having a bit rate of 64 kbps when the identification pattern detecting section detects an identification pattern. The pass through frame processing section converts a digital voice signal in the pass through frame format received from the digital exchange into an RTP packet when the identification pattern detecting section detects no identification pattern. A digital one-link tandem exchange method is also disclosed.

Abstract: La présente invention concerne un procédé consistant à exposer une structure à un premier rayonnement électromagnétique comportant au moins une longueur d'ondes absorbée par une substance définie à rechercher. La substance recherchée peut être l'eau, une substance hydrosoluble ou un champignon dont la présence peut être source de problèmes importants dans une structure telle qu'une maison ou un bâtiment. Le procédé consiste ensuite, connaissant le premier rayonnement, à détecter un second rayonnement électromagnétique provenant de la structure. Le procédé consiste ensuite à vérifier, d'après le second rayonnement détecté, si la substance recherchée est présente dans la structure. Si la substance recherchée est l'eau et que la phase d'évaluation révèle dans la structure une zone éventuellement humide, le procédé peut se poursuivre par une analyse de cette zone éventuellement humide visant à confirmer la présence d'eau dans la structure. Si cette analyse confirme la présence d'eau dans la structure, on peut compléter le procédé par une recherche de la provenance de l'eau.
