Patent CA-2302672-A1 (CA)
Inventor: PARKER DONALD R
IPC: H01L39/24
Filed: 1998-09-08
Abstract: A novel process of the production and processing of high quality, high Tc BSCCO or (Bi, Pb)SCCO superconductors starts with fabrication of a forming of a bundle including a plurality of billets, each billet containing at least one filament comprising a dominant amount of a tetragonal BSCCO phase with selected intermediate phases, and substantially surrounded by a constraining metal. The bundle is thermomechanically consolidated to form a multifilamentary precursor article by applying pressure and heat to the bundle under conditions cooperatively selected to cause interdiffusion of said constraining metal at the interfaces between said metal and said filaments and substantially complete elimination of voids in said bundle, and the consolidation step is completed before any high strain longitudinal deformation is performed on the bundle. The precursor article is then heated at a second selected processing temperature in an inert atmosphere with a second selected oxygen partial pressure for a second selected time period, the second processing temperature, the second time period and the second oxygen partial pressure being cooperatively selected to form a dominant amount of an orthorhombic BSCCO phase in the reacted mixture. It may then be deformed to form an elongated precursor article of a desired texture; and thereafter heated at a third selected processing temperature in an inert atmosphere with a third selected oxygen partial pressure for a third selected time period, all cooperatively selected to convert at least a portion of the orthorhombic BSCCO phase to the final superconducting BSCCO material.

Patent CA-2307605-A1 (CA)
Inventor: MASSEY DAVID EARL
IPC: H04W4/00
Filed: 1998-10-23
Abstract: A shared single system of ground stations (120) for servicing any number of satellite owners, permits the owners to transfer command information to their satellite (110), and collect data streams that are sent back from the satellite all via a standardized global communications system maintained and operated by a commercial satellite communications company. A remotely controlled ground station (120) is operated and controlled from a central controller. Each user creates and stores a ground station configuration file at the central controller, which file contains the data necessary to configure the remotely controlled ground station (120) to communicate with the user's satellite (110). When the user desires to communicate with the user's satellite, the user schedules a communication session with the central controller, which downloads the configuration file to the appropriate ground station. The appropriate ground station is determined based on current orbital characteristics of the satellite in question. A server at the ground station then uses the data in the configuration file to configure the equipment at the ground station to communicate with the desired satellite.

Abstract: L'invention concerne une unité de fermeture de moule comportant un premier dispositif (30) servant au déplacement d'un porte-moule (11) mobile en direction du porte-moule fixe, ou à partir de celui-ci. Si l'on intercale un second dispositif, le premier dispositif vient en contact avec son élément rotatif et est coupé du flux de forces. D'autres forces produites par le second dispositif sont transmises au porte-moule mobile par l'intermédiaire d'un élément de transmission de forces se présentant sous la forme d'un tube à pression (19). Une chambre de commande (41) pouvant être soumise à l'action d'un fluide hydraulique, conçue comme un moyen de désaccouplement, est placée entre l'élément de transmission de forces et l'élément de support (13), la pression régnant dans la chambre de commande (41) pouvant être mise en circuit à volonté, tout comme le second dispositif. On obtient ainsi une transition pouvant être commandée entre le premier dispositif et le second dispositif.

Title: Method of and system for characterization of fiber optic connections in situ
Inventor: WOODS JAMES W
IPC: H04B10/2581
Filed: 1998-11-18
Abstract: A test method and system for the testing of fiber optic connectors in a fiber optic system while the system is operational without external test equipment. An input signal is applied to one end of a fiber optic path comprising a plurality of connections, which results in an output signal. The input signal has known characteristics (e.g., a training pulse) over the fiber optic path. The output signal, which is generated in response to the input signal, is converted from a time domain expression to a frequency domain expression using, for example, Fourier transform analysis. Then, the frequency domain expression of the output signal is combined with a frequency domain expression of the input signal to provide a waveform from which the location of each connector and its relative level of performance can be determined. Advantageously, the method and system do not require disassembly of the fiber optic path.
Patent CA-2319892-A1 (CA)
Inventor: PETEK HRVOJE
IPC: H04B10/29
Filed: 2000-09-15
Abstract: In the wavelength-division-multiplexed optical transmission, laser diodes of the number of multiplicity are disposed as a light source to configure a transmitter. However, since this method requires a large number of light sources and highly precise wavelength control, a cost and an apparatus are increased. An ultrashort pulse solid-state laser is used as the light source of the transmitter and its wide spectrum is taken out by a splitter to be assigned to each channel, so that the number of light sources can be reduced greatly. The transmitter requires high repetition rate such as 2.4 GHz, 10 HGz and the like as the repetition rate of the ultrashort pulse solid-state laser, while by configuring the resonator only by two components as shown in Fig. 1, the high repetition rate can be attained. Since each channel is produced passively from the splitter, very precise wavelength management is not required. The light source is made small and the number thereof is reduced. Consequently, the whole apparatus is made small and a cost thereof is also reduced.

Patent CA-2329178-A1 (CA)
Inventor: HIGUMA TOSHIYASU
IPC: H04L12/403
Filed: 2000-02-21
Abstract: When a primary modulation/demodulation method used by existing power line modems connected to the same power line is changed, a concept of a virtual master is adopted. Specifically, if a power line modem among multiple power line modems connected to a power line (7) judges that the communication quality is difficult to ensure by the current primary modulation method, the power line modem serves as a virtual master in a primary modulation change processing. The virtual master sends a change request command presenting the next primary modulation method to the other power line modems. If a change reject command is not replied from any of the other power line modems having received the change request command, the primary modulation method currently used by the power line modem serving as the virtual master is changed to the next primary modulation method and a change instruction command is sent to the other power line modems. Lastly, the other power lines having received the change instruction command change the current primary modulation method to the specified primary modulation method.
