Patent CA-2346476-A1 (CA)
Inventor: GREGOIRE SCOTT P
IPC: H01Q1/24
Filed: 2000-08-09
Abstract: The ubiquitous mobile subscriber station of the present invention enables the subscriber to receive wireless cellular mobile telecommunication services in a unified manner in both the terrestrial (ground-based) and non-terrestrial regions. The ubiquitous mobile subscriber station extends the usage of existing cellular mobile telecommunication frequencies allocated for ground-based cellular communications to non-terrestrial cellular communications in a manner that avoids the possibility of signal interference between the ground-based and non-terrestrial mobile subscriber stations. In particular, the ubiquitous mobile subscriber station automatically transitions between the communications paradigm used in ground-based cellular communications and the communications paradigm used in non-terrestrial cellular communications as a function of the present location of the ubiquitous mobile subscriber station.      The subscriber therefore can use the ubiquitous mobile subscriber station in all locations for uninterrupted wireless communications services. In addition, the non-terrestrial capabilities of the ubiquitous mobile subscriber station can be used to implement data transmission capabilities for use in the aircraft to provide Flight Information Services, real time monitoring of aircraft operation, as well as enhanced data communication services for the passengers in the aircraft.

Title: Sub-atmospheric gas delivery method and apparatus
Inventor: LANGAN JOHN GILES
IPC: G05D16/10
Filed: 2001-08-10
Abstract: An apparatus for containing and delivering hazardous gases at sub-atmospheric pressure from a pressurized container is provided which includes a valve body in sealed communication with an outlet orifice of the pressurized container. The outlet orifice of the pressurized container is open to an interior chamber of the pressurized container. A fluid discharge path is located in the valve body, between the outlet orifice of the pressurized container and an outlet orifice of the valve body. A pressure regulator having a pressure sensing means capable of responding to sub-atomospheric pressure, is integral to the valve body, in-line in the fluid discharge path with the pressure regulator pre-set to a pressure below atmospheric pressure to allow the gas to be delivered through the regulator from the interior chamber only when the pressure regulator senses a downstream pressure at or below the pre-set pressure.  Finally, a high pressure shut-off valve integral to the valve body and in-line in the fluid discharge path and upstream from the pressure regulator is included. The gas flows through from the interior chamber of the pressurized container through the fluid discharge path, through the outlet orifice of the pressurized container, and through the outlet orifice of the vale body only when the outlet orifice is connected to a vacuum system. A  method of containing and delivering hazardous gases at sub-atmospheric pressure is also provided.

IPC: H04W8/26
Filed: 2001-09-06
Abstract: There is disclosed a communication network for supporting mobile IP (MIP) protocol having a home network and a visiting network with a foreign agent that has optimized communications between at least two visiting mobile nodes from the same home network. The optimization in communications is achieved by the common foreign agent maintaining a listing of the visiting mobile nodes from the same home network utilizing the common foreign agent for IP care-of-addresses. The common foreign agent utilizes this listing to route all packets transmitted between the at least two visiting mobile nodes from the same home network maintained on the listing directly to the link layer addresses of such mobile nodes known to the common foreign agent. In one embodiment, the home network forwards a prior authorization message to the common foreign agent authorizing the common foreign network to optimize communication between at least two visiting mobile nodes from the home network. In another embodiment each visiting mobile node requests and is subsequently authorized by the home network to have the common foreign agent to optimize communication with other visiting mobile nodes from the home network who have also so authorized the common foreign agent to optimize communications.

Inventor: WORK JOSEPH M
IPC: B65G47/91
Filed: 2001-10-30
Abstract: An apparatus is described for supplying contoured packing trays, such as molded pulp apple trays, from a nested stack of trays onto an associated conveyer. The apparatus includes receptacles for holding nested stacks of trays, and sensors which protect the operator while he/she is reloading the receptacles. Rails are positioned above the receptacles which extend to a position above the conveyer. A slidable carriage moves on the rails from a first position over the nested stack of trays to a second position above the conveyer, and the movement of the carnage is pneumatically driven. The carriage includes a system of manifolds, which deliver low vacuum to soft, flexible suction cups provided on the carriage. The use of large surface area suction cups and low vacuum helps to control one at a time delivery of trays from the nested stacks.
Patent CA-2360706-A1 (CA)
Inventor: OKSANEN KARI JUHANI
IPC: F16K31/126
Filed: 2001-10-31
Abstract: A pressure relief valve for relieving excess pressure in a fluid distribution system comprising a valve body having an inlet port and an outlet port in communication with an interior of the valve body. The inlet port is connectable to the fluid distribution system. A valve member within the interior of the valve body is movable between a closed position to prevent fluid flow through the body and an open position to permit fluid flow. The valve member is exposed to a first opening force exerted directly by the pressure in the fluid distribution system. There is a movable piston/diaphragm member co-operating with the valve member such that the piston/diaphragm is exposed to the pressure in the fluid distribution system to provide a second opening force for the valve member. A biasing system exerts a default closing force to move the valve member to the closed position. The closing force is set to be equivalent to a pre-selected pressure in the fluid distribution system. The opening forces of the system pressure on the valve member are supplemented by the opening forces of the system pressure acting on the movable member to readily move the valve member to the open position whenever the pressure in the fluid distribution system exceeds the pre-selected pressure.      The pressure relief valve can be used in both clean and dirty fluid applications. The valve unit provides quick detection and opening of the valve member to relieve overpressures in the fluid distribution system.
