Patent CA-2304096-A1 (CA)
Title: Sustained-release liposomal anesthetic compositions
Inventor: KIM SINIL
IPC: A61K9/127
Filed: 1998-09-18
Abstract: The invention provides a method for obtaining local anesthetics encapsulated in liposomes, such as multivesicular liposomes, with high encapsulation efficiency and slow release in vivo. When the encapsulated anesthetic is administered as a single intracutaneous dose, the duration of anesthesia and half-life of the drug at the local injection site is increased as compared to injection of unencapsulated anesthetic. The maximum tolerated dose of the encapsulated anesthetic is also markedly increased in the liposomal formulation over injection of unencapsulated anesthetic. These results show that the liposomal formulation of local anesthetic is useful for sustained local infiltration and nerve block anesthesia.

Patent CA-2308473-A1 (CA)
Title: System and method for electronically identifying connections of a cross-connect system
Inventor: KOZIY ROBERT J
IPC: H04M3/24
Filed: 1998-11-17
Abstract: A system and method for electronically identifying connections established through a cross-connect system provides for the identification of all hardwired and temporary patch connections, and any modifications made to existing cross-connect circuit connections. Connection identification and status information is acquired in near real-time and stored in a database which is accessible by a user through a graphical user interface (GUI). The TRACE or lamp wires which connect respective pairs of cross-connect circuits are utilized in an unconventional manner so as to form a scanning bus. The information signal paths established through the cross-connect circuits remain undisturbed. A scanning signal is communicated between each pair of crossconnected circuits over the TRACE conductor. In the event a patch cord is used to temporarily redirect a signal connection, the scanning signal is transmitted over the shield or sleeve conductor of the patch cord. The scanning signal provides identification and other information concerning the transmitting circuit. A circuit receiving the scanning signal communicates its identification information and that of the transmitting circuit derived from the scanning signal to a central computer. The identification information acquired by the central computer from all receiving cross-connect circuits provides identification and status information for all circuits within the cross-connect system. In one embodiment, all circuits of a cross-connect system are scanned and identification information acquired in the time required to transmit a single cross-connect circuit ID bit string, irrespective of the total number of cross-connect circuits included within the cross-connect system.
