Patent CA-2290383-A1 (CA)
Title: Method for surveying a predetermined surveillance area
Inventor: WEGMANN MAX
IPC: G08B25/00
Filed: 1998-06-03
Abstract: The invention relates to an automatic surveillance system whereby characteristic data are first determined from a section of a signal, e.g., an instantaneous video image, using an automatic image analysis. This data is then stored temporarily or permanently with a time tag, so that it can later be compared statistically with certain other time references. This statistical comparison enables the inventive surveillance system to identify abnormal situations and to selectively bring them to the attention of the surveillance officer. The invention is characterised in that the system itself identifies which situations are abnormal and require closer examination. It is not necessary to specify in advance what constitutes abnormal in a given surveillance situation, since after a certain period of running, the system itself will have collected the data corresponding to a normal situation.

Patent CA-2293612-A1 (CA)
Inventor: YAO FENG
IPC: A61K39/00
Filed: 1998-05-29
Abstract: The present invention is directed to DNA constructs suitable for gene expression in mammalian cells and which are characterized by the presence of a mammalian promoter under the control of a tet operator/repressor system. The DNA may be used as part of a system for expressing recombinant protein. In addition, the tet operator/repressor system can be used to engineer cis- and trans-destructive viruses which are capable of replicating in the presence of the tet repressor, but not in the absence of the repressor. These viruses can be used either directly in the treatment of patients with corresponding viral diseases, as vehicles for the delivery of nucleic acids that can serve as therapeutic agents and as part of vaccines designed to immunize people or animals against viral diseases.

Patent CA-2298933-A1 (CA)
Title: Method for transferring data using permanent identifier including routing information
Inventor: ROLLENDER DOUGLAS HAROLD
IPC: H04M11/00
Filed: 2000-02-17
Abstract: The method for transferring data sends the data as part of a first permanent identifier associated with an end user in a communication system. The first permanent identifier is sent along with a second permanent identifier, also associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the first permanent identifier includes routing information to a home system forming part of the communication system. Based at least in part on recognizing the second permanent identifier, a home system sends at least the first permanent identifier to a destination entity. The destination entity extracts the data from the first permanent identifier. In this manner, a traffic channel does not need to be established to transmit the data.
Patent CA-2299673-A1 (CA)
Inventor: SHOOFLAR HENRY
IPC: B64D45/00
Filed: 2000-02-24
Abstract: Smoke Holes are openings from four to ten inches in diameter enclosed in the walls of an Aircraft that includes a controllable pneumatic piston that is built into a larger mechanism called The Porthole Assembly.      The interior of the Porthole Assembly has a built in Storz Female Fire hose adapter that will accept a male Storz fire hose adapter when the Fire fighter makes the connection of a Storz connected fire hose or dual fire hose system from the outside of a burning aircraft.      Storz fire hose adapters are the most widely used adapters by Airport fire fighters so a fire hose can be connected to the Aircraft through the Smoke Hole Assembly Porthole at any of the worlds major airports.      The smoke hole mechanism will be installed in the centre of the aircraft on each side to permit a double connection when required.A series of two inch wide or more aluminum pipe that enters both sides of the Smoke hole mechanism completely encircles the fuselage wall of the aircraft.      This aluminum hose will carry either water or air and smoke depending on the required circomstances.      During an Aircraft fire on an airport tarmac the passengers will be fleeing the plane from all available exits. The firemen will connect their hoses to the Porthole opening and water will flow into the aluminum hose with nozzles contained inside the fuselage wall to contain electrical fires originating in the fuselage walls. Other nozzle outlets from the same sprinkler system wilt be sprinkling water on the escaping passengers whose clothes may be on fire.        SMOKE EXPULSION IN FLIGHT:      In flight the Smoke Hole Assembly system will be used to eject smoke from specific areas inside the aircraft at a much faster rate then the existing airconditioning system which ejects smoke in a universal manner taking four minutes for a complete air change cycle.      The smoke HOLE Mechanism will not replace but augment all the existing systems to give the Pilot an additional life saving resource. The Smoke HOLE mechanism also contains two side trajectories that can be used to eject parachutes to slow down the fall of a stricken aircraft as well as an exit zone for AIRBAGS to keep the plane afloat following air crashes over water, These trajectories can also be used to accept fire hoses from any source if the airport is not equipped with acceptable Storz connected hoses.
