Patent CA-2179215-A1 (CA)
Title: Video messaging arrangement
Inventor: BRUNSON GORDON RICHARDS
IPC: H04N21/232
Filed: 1996-06-17
Abstract: Video and telephony messaging are integrated by a telephony multi-media messaging system (101) connected to a plurality of video workstations (103-104) by a LAN or WAN (100). The workstations are connected to ISDN telephone lines (153-154). The workstations answer video calls on the video lines and/or on the LAN or WAN that go unanswered by users, record video messages from the video calls, and send the video messages via the LAN or WAN to the messaging system for storage. They also retrieve stored video messages via the LAN or WAN from the messaging system and play them to users. The messaging system stores both video and non-video messages and has a telephony user interface (114-115 and 118) for storing and retrieving non-video messages and for accessing non-video portions of all messages. The video terminals perform functions, such as answering of video calls and recording of video messages, on behalf of the telephony messaging system which cannot itself perform those functions, while the messaging system performs functions, such as providing a rich set of messaging features and providing telephony access from a variety of different telephony terminals to at least portions of the video messages, on behalf of the video terminals which cannot themselves perform those functions.

Patent CA-2186794-A1 (CA)
Inventor: HOLTZ ROGER EDWARD
IPC: H04M1/26
Filed: 1996-09-30
Abstract: Automatic dialing mode selection techniques are utilized in the operational environment of a telephonic device connected to a tip-ring line. The telephonic device includes dialing mode assessment circuitry and dialing mode setting circuitry. The dialing mode assessment circuitry automatically determines the dialing mode supported by the tip-ring line. The dialing mode setting circuitry is responsive to the dialing mode assessment circuitry for automatically setting the dialing mode of the telephonic device to specify the dialing mode supported by the tip-ring line, such as pulsed dialing or touch-tone dialing.  The dialing mode is automatically set at the time that the telephonic device is first connected to the tip-ring line, and the telephonic device retains that mode setting until the device is removed from the tip-ring line.

Patent CA-2224120-A1 (CA)
Title: Replication of nucleic acids using single-strand dna binding proteins
Inventor: FRAISER MELINDA S
IPC: C07K14/39
Filed: 1998-02-24
Abstract: Single-strand DNA binding proteins have been found to increase the efficiency ofstrand-displacement replication of long targets, and when added to amplification reactions such as SDA, they significantly improve the amplification efficiency of targets which are otherwise too long to be efficiently amplified.  The gp32 protein of T4 has been shown in SDA to produce about 10 6 to 10 8-fold amplification in 15-20 min. for targets about 800-1,000 bp in length.  In the absence of gp32 there is essentially no detectable amplification for targets of this length.  Targets about 400-500 bp in length are amplifiable about a billion-fold in the presence of gp32, representing an amplification factor approximately equivalent to that observed for targets less than 100 bp in length in conventional SDA reactions in the absence of SSBs.  Other single-strand DNA binding proteins have also been shown to improve replication and amplification efficiency for long targets.
