A  communication network (110) supporting the information channel, command channel and back channel is coupled between the service provider equipment and the subscriber equipment (124).
Patent CA-2278072-C (CA)
Inventor: LONG WILLIAM H JR
IPC: H01S3/06
Filed: 1999-07-16
Granted: 2001-12-11
Abstract: A relatively high average power optical laser utilizes a diode pumped multi-mode dual-clad fiber amplifier configured for double pass amplification to provide a relatively higher average power than single mode fiber amplifiers. In order to compensate for mode scrambling and depolarization from the multi-mode fiber amplifier, the output beam from the mufti-mode fiber amplifier is applied to a vector phase conjugator after a single pass through the amplifier and reflected back into the amplifier. The vector phase conjugator conjugates the electric field amplitude, phase and polarization and reflects a conjugate wave back into the mufti-mode fiber amplifier in a reverse direction. The propagation of the conjugate wave through the amplifier unscrambles mode mixing and restores the beam back to its original polarization state. A Faraday rotator and polarization beam splitter are used to outcouple an output beam after the second pass through the mufti-mode fiber amplifier.

Abstract: A composite elastomeric spring having a predetermined final shape and including a first member of elastomeric material having a first durometer hardness, and a second member of elastomeric material having a second durometer hardness is disclosed. The second member has a predetermined initial shape complimentary to an initial shape of the first member. The second member is positioned adjacent and in circumferential surrounding relation relative to the first member to define a preform composite spring member. After the second member is positioned about the first member, a force is applied to the preform composite spring member sufficient to simultaneously compress the first member and the second member thereby permanently changing the initial shapes of the first member and second members such that the first and second members are thereafter maintained in captured relationship relative to each other. The force is then removed from and thereby allowing the preform composite spring to transmute to the final shape of the composite elastomeric spring.

Title: Cabine de sauvetage avec parachute pour la navigation aerienne
Inventor: PAULMIN FRANCOIS
IPC: B64D25/12
Filed: 1999-11-23
Granted: 2009-02-03
Abstract: La présente invention se rapporte à une cabine de sauvetage avec parachute (fig. 1a) pour la navigation aérienne. L'appareil de transport contiendra le nombre de cabines de sauvetage nécessaires pour l'évacuation en vol des passagers et de l'équipage. Dans le cas d'une détresse aérienne, les tentatives de sauvetage sont l'atterrissage ou l'amerrissage d'urgence. Ces deux procédés n'ont d'issue favorable que dans un nombre restreint de cas répondant à des critères particuliers (proximité d'un aéroport ou d'un rivage, absence de zones habitées ou industrielles). J'ai découvert que l'équipage et les passagers d'un avion peuvent avoir un e seconde chance en quittant l'appareil de transport en plein vol dès les premiers signes de détresse de celui-ci.

Abstract: Le procédé de la présente invention consiste à introduire des réactifs gazeux dans un lit fluidifié de particules en suspension dans un liquide. Les réactifs gazeux (13) réagissent dans le lit fluidifié (16), jusqu'à former des produits liquides, et éventuellement des produits gazeux. Le liquide vient former, avec le liquide de suspension, une phase liquide du lit fluidifié.

Au niveau du caisson de tête, la phase gazeuse est soumise à une distillation, et éventuellement à un lavage, pour séparer de la phase gazeuse toutes les particules solides ainsi que la phase liquide entraînées. Toutes ces particules solides et phase liquide entraînées sont renvoyées dans le lit fluidifié. Le soutirage (44, 46) du gaz traité intervient dans le caisson de tête.

Title: Load based priority for the mobile subscriber
Inventor: BHATIA RANJIT
IPC: H04W72/10
Filed: 1998-10-08
Granted: 2005-07-19
Abstract: A "load based priority" telecommunications system and method which provides efficient use of Traffic Channels (TCHs), while both meeting the subscriber's needs and producing revenue for the cellular operator. "Load based priority" for the mobile subscribers consists of assigning a priority to the subscriber at the time of service activation.  The subscriber can pay a low rate for lower priority subscriptions and a higher rate for higher priority subscriptions. The system continuously checks the traffic load on the TCH and broadcasts the current priority in the system information message to the mobile stations in the cell.  For example, if the system broadcast message reads low priority, then all mobile subscribers will be able to make calls. However, if the system broadcast message reads high priority, then mobile subscribers who have purchased a lower priority subscription will not be able to make calls.

Title: Passenger entrance ramp for mass transit vehicle
Inventor: MELANSON DEAN B
IPC: A61G3/06
Filed: 2000-04-20
Granted: 2002-07-30
Abstract: A public transit vehicle has a passenger entrance ramp at a door way including a support frame for mounting on the vehicle at the doorway carrying a primary ramp panel, a secondary ramp panel and a fixed platform panel. The primary panel is pivotal through 180 degrees between a retracted position inverted within the vehicle and covering the secondary panel and the fixed platform panel and a deployed position in which the primary ramp panel is inclined from an inner edge downwardly and outwardly from the vehicle to an outer edge at the ground. The primary panel is pivoted at its inner edge on an outer edge of the secondary ramp panel pivotal which is in turn pivotal about an inner horizontal axis at its inner edge. The primary and secondary ramp panels are thus arranged such that, in the retracted position, the outer edge of the secondary panel is in the raised position so that both the primary and secondary ramp panels are substantially horizontal and, in the deployed position, the outer edge is moved to the lowered position so that the primary and secondary ramp panels form a common ramp surface inclined outwardly and downwardly from the inner edge of the secondary ramp panel to the outer edge of the primary ramp panel.

Abstract: A snap closure for a flexible, gusseted package and a flexible gusseted packing including the closure. The package includes a mouth portion arranged to be opened to provide access to the contents of the package. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets. The panels and gussets each include a top portion, which between them define the package's mouth. The package's mouth is initially sealed but arranged to be opened, e.g., peeled apart. The snap closure enables the resealing of the mouth of the package and is made up of a pair of elongated elements, one of which includes a tongue extending along the length of it. The other element includes an undercut groove extending along the length of it. The elements are arranged to be pressed together, whereupon the tongue of the one element enters the groove of the other element with portions of the panels and side gussets tightly interposed therebetween. The closure elements may be longitudinally rigid or may be segmented to flex in the longitudinal direction to facilitate opening. Moreover, the closure elements may be a part of the package or separate components for use therewith. In any case when the closure is utilized it recloses the mouth of the package to preclude or minimize the ingress of air into the package.

Abstract: A fiber reinforced composite wood board is designed particularly for use in the flooring of truck trailers which experience adverse operating conditions such as from heavy loads of lift trucks on the top side and water spray during rainy periods on the bottom side. The composite wood board comprises an edge-glued laminated wood member composed of wood segments with end joints. The wood member is underlaid with a thin layer of fiber reinforced plastic. The top surface of the composite wood board is the same as that of the laminated wood. The fiber reinforced plastic underlay is composed of glass and/or carbon fibers embedded in a polymeric resin such as epoxy, phenolic, vinyl ester, polyester, polypropylene or polyamide resin.  Further, the fiber reinforced plastic underlay is substantially bonded to the wood member with a reactive hotmelt adhesive. The fiber reinforced plastic provides high fatigue resistance to the composite wood board and prevents water leakage into the trailer through the end joints of the wood segments.
