Patent CA-2288033-A1 (CA)
Inventor: BHAGAVATULA VENKATA A
IPC: G02B6/02
Filed: 1998-04-14
Abstract: L'invention concerne une fibre optique guide d'ondes à dispersion modulée. La perte de puissance due au mélange à quatre ondes est maintenue à un faible niveau du fait que le guide d'ondes est fabriqué à partir de longueurs de fibre à dispersion non nulle. On fait alterner le signe de la dispersion totale des sous-longueurs, sur la longueur du guide d'ondes, ce qui permet la modulation de la dispersion totale du guide d'ondes de sorte qu'une valeur cible sélectionnée soit obtenue. On a découvert que l'on obtient les meilleurs résultats lorsque les guides d'ondes à dispersion nulle des sous-longueurs sont séparés par des grandes distances et de manière asymétrique. Il est avantageux de modifier le profil d'indice de réfraction central pour des sous-longueurs ayant une dispersion totale à signe différent.

Title: L-band mode-locked fiber laser
Inventor: ATIEH AHMAD K
IPC: H01S3/098
Filed: 1999-11-15
Abstract: A mode-locked fiber laser comprises an L-band optical fiber amplifier, conveniently an erbium-doped fiber amplifier, operable at wavelengths from about 1565 nm to about 1610 nm and a pumping device, such as a diffraction grating having a reflection wavelength range from about 1525 nm to about 1565 nm. The pumping device comprises a pump source for the L-band EDFA and a fiber Bragg grating that effectively converts the amplified spontaneous emission produced in the lower range of wavelengths to energy at wavelengths in the higher range so that the laser provides a useful output in the L-band range of wavelengths. In one preferred embodiment of the invention, a figure-eight laser can operates to generate stable soliton pulses with widths as short as 200 fs in the L-band wavelength range (1565 nm - 1610 nm). The laser may produce a tunable single wavelength CW, or dual wavelength CW light.

IPC: H04B10/80
Filed: 1999-09-09
Abstract: A free space optical interconnect system tolerant to misalignments and utilizing redundant elements of a transmitter and/or a receiver is provided.  The elements are arranged into clusters, the number of clusters being redundant, and the number of elements in each cluster being sufficient to accommodate the number of data channels to be transmitted. The system also includes means for identifying misalignments between the transmitter and the corresponding receiver, including means for providing feedback between the transmitter and the corresponding receiver regarding the misalignment, and means for re-routing data from the cluster which is misaligned to the redundant cluster which thus redirects data to/from the correct physical location. Preferably, the elements are arranged into one-dimensional or two-dimensional arrays, the elements of the transmitter being optical emitters or optical modulators. Uni-direction and bi-directional link systems are implemented in various embodiments of the invention. A method for compensating misalignments in a free space optical interconnect system having redundant elements of the transmitter or the receiver is also provided.

Patent CA-2315823-A1 (CA)
Inventor: LINDHOLM HEIKKI
IPC: H04W60/00
Filed: 1998-12-11
Abstract: The basic idea of the invention is to separate the location area used in the RAN  and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.

Patent CA-2318510-A1 (CA)
Title: Weather resistant panels
Inventor: STEEL IAIN
IPC: B32B38/06
Filed: 1999-01-08
Abstract: The use is described of rigid foam cores in panels, especially doors, of the kind comprising a foam core (22) between two moulded skins (8, 10). The weather-resistance, especially the resistance to thermally-induced bowing, of such panels is improved by forming the panel of at least one vacuum-formed thermoplastics skin (8, 10) adhesively bonded to a substantially open-cell, rigid foam core (22). If the foam has frangible cell walls, it can be conformed to accommodate the depressed zones of a moulded overlying door skin (8, 10) by crumbling under compression, with fracture of the cell walls to accommodate the zones. A preferred open-cell rigid foam is a phenolic foam reinforced with finely divided particulate filler.

Title: Pest control system
Inventor: DANLEY THOMAS T
IPC: A01M1/24
Filed: 2000-09-13
Abstract: A method of pest control which includes heating the effected area to a temperature which is lethal for the pest being exterminated, and maintaining this elevated temperature in the zone for a period of at least about eleven hours. The treatment is undertaken after determining the air penetration parameters for the treatment zone, so as to be able to determine the CFM requirements for achieving an air flow rate of between three and five air changes per hour in the treatment zone. Heated outside air is introduced to the treatment zone at a temperature of at least 200°F., with the temperature in the treatment zone being elevated at a rate of between about 5°F. and 10°F. per hour until the air temperature reaches the lethal level.

Title: Installation structure of a power circuit unit, installation structure of a circuit board and installation method of a power circuit unit
Inventor: SUZUKI SADANORI
IPC: H01L23/34
Filed: 2000-11-17
Abstract: Leads of a semiconductor device are soldered to a printed-circuit board in a state where the side opposite to the heat radiation surface of the semiconductor device abuts one side of the printed-circuit board. Then, the printed-circuit board is fixed to a heat radiator so that the heat radiation surface of the semiconductor device contacts the heat radiator via an elastic body. As a result, the force that is exerted on the semiconductor device when the printed-circuit board is installed on the heat radiator is absorbed by the elastic body, whereby no stress is applied to the soldered portion of the semiconductor device.

Title: Reserving resources for anticipated work items via simulated work items
Inventor: MULLEN DAVID
IPC: G06Q10/06
Filed: 2001-01-09
Abstract: A workflow-manager (150) reserves a resource for processing an anticipated real work item by sending a simulated, artificial, work item to the resource before the real work item becomes available. The resource does not process the simulated work item, but rather awaits the real work item. When the real work item becomes available, it is substituted for the simulated work item, and the resource processes it.      For example, in an ACD system (101) that processes various types of communications, it is anticipated on a per-type basis how many agents (102-104) will be needed (202) versus how many are available (204). Any shortfall is cured by generating (210) tokens representing that many simulated communications of that type and enqueuing, dequeuing, and assigning the tokens to agents like any other arriving communications. Any excess is cured by canceling (210) that many outstanding, pending, tokens of that type. When a real communication of that type arrives (300), it is substituted (312,314) for the oldest token of that type, either in queue or at an assigned agent. To be fair to all agents, an assigned token is periodically reassigned from one agent to an available another agent.
