Patent CA-2209593-A1 (CA)
Title: Dispositif a faisceau d'electrons dote d'une fenetre en monocristal et d'une anode adaptee
Inventor: WAKALOPULOS GEORGE
IPC: B29C35/08
Filed: 1996-01-03
Abstract: Un dispositif à faisceau d'électrons (15) doté d'un tube à vide comprend une membrane (20) en monocristal fine, perméable aux électrons, mais imperméable aux gaz pour la transmission des électrons. Etant donné sa solidité mécanique, la membrane en monocristal peut présenter une faible épaisseur en raison de sa grande solidité et est donc extrêmement transparente aux électrons libres. La structure cristalline ordonnée de cette membrane offre une résistance minimale aux faisceaux d'électrons, mais par contre assure une imperméabilité élevée à la pénétration des molécules de gaz et de liquide. Une anode en silicium dopée (19) ayant des caractéristiques de dilatation thermique correspondant à celles de la membrane peut constituer un support pour celle-ci. Une anode cristalline peut être formée d'une pièce avec la membrane. Dans une forme d'exécution à deux membranes, le fluide de refroidissement est confiné de sorte qu'il passe à proximité des deux membranes.

Abstract: Circuit de tête de lecture/écriture assurant l'équivalence entre la fréquence d'un signal d'attaque et la résonance d'un circuit à résonance composé d'un capteur inductif raccordé en parallèle à un condensateur. On utilise un oscillateur commandé en tension (38) (VCO) pour engendrer des impulsions de synchronisation (54) à partir du générateur (33) de courant d'attaque, la tension de commande étant obtenue par comparaison des phases de la tension et du courant d'attaque au travers du circuit à résonance composé du capteur (11) et du condensateur (17) raccordés en parallèle. Ce circuit assure également une limitation de l'amplitude du signal d'attaque par régulation des impulsions du courant d'attaque appliquées au capteur inductif.

Patent CA-2221176-A1 (CA)
Inventor: NICHOLSON JAMES E
IPC: G01J7/00
Filed: 1996-05-09
Abstract: An incident optical signal is captured by an array of apertures and directed to pairs of fibers, each pair having a delay fiber with a unique length and a no-delay fiber. Each pair of fibers further has a unique transmission characteristic. Time interpolation is then performed using the transmission characteristic curve for each delay fiber and the duration from the time the optical signal arrives over the no-delay fibers and the time the signal arrives over the delay fibers to determine the wavelength. In a second embodiment, each pair of delay and no-delay fibers is replaced by a fiber splitter which directs light into a no-delay fiber and a delay fiber that have been split from the input of the splitter. In a third embodiment, two fiber splitters are used in place of the pairs of fibers. Each splitter has a number of branches for receiving light and an output end for guiding light onto the photodetectors. The propagation time of the delay optical signal, as compared against the no-delay signal, and other factors such as the length of the individual fiber and the transmission characteristics, are used to determine the wavelength.

Title: Method and system for completing a voice connection between first and second voice terminals in a switched telephone network
Inventor: REID COLIN A
IPC: H04M3/38
Filed: 1997-12-24
Abstract: A method and a system for completing a voice connection between a first and second voice terminals in a switched telephone network are disclosed. The system includes a Virtual Switching Point (VSP) in a switched telephone network having a connection to a data network such as the Internet. Call requests are received by the VSP from the data network and processed by the VSP to establish a voice connection between a calling party which initiates the call request and a called party number indicated in the call request message. The call request message may include a plurality of called party numbers and the VSP completes calls to each number in sequence without terminating the voice connection with the calling party, until an attempt to connect with each of the called numbers has been made or a call control option is exercised by the calling party. The advantage is an efficient, reliable method of initiating calls from a data network to permit a multi-call session without disconnection or dialing between calls and fully functional computer telephony integration and control over calling connections using the inherent switching power resident in the switched telephone network.

Title: System of controlling wavelength division multiplexed optical amplifier and method thereof
Inventor: CHOI DOE-IN
IPC: H04B10/00
Filed: 1998-07-10
Abstract: Wavelength division multiplexed optical amplifier controlling system and method are provided. The wavelength division multiplexed optical amplifier controlling system includes an optical exchange system for generating and interpreting a supervision channel optical signal, multiplexing the supervision channel and data channels comprised of a plurality of optical signals having different wavelengths, and transmitting and receiving the multiplexed channels and a plurality of optical amplifying portions located on a transmission path connected to the optical exchange system, for performing amplification so as to have even gain with respect to predetermined wavelength range which the data channel optical signals have according to the supervision channel optical signal information, and inserting the state information thereof into the supervision channel when the optical exchange system requests the state information thereof. According to the present invention, since an optical filter in each wavelength for supervision in a WDM-EDFA because a supervision channel having a predetermined wavelength is used is not necessary, the structure of the WDM-EDFAbecomes simpler. Therefore, it is possible to lower costs and there is no loss of optical signals which occurs by using a conventional optical demultiplexer.

Title: An apparatus for storing and transmitting data
Inventor: SATO KOICHI
IPC: H04N7/173
Filed: 1998-10-26
Abstract: This invention relates to an apparatus for storing and transmitting AV data. A receiving buffer unit for storing AV data temporarily, a transmitting buffer unit for storing temporarily the AV data to be transmitted, and a primary storage unit for storing AV data and a secondary storage units for storing AV data are connected to each other by means of a subnetwork. A server control unit for controlling the respective units is connected to the subnetwork. Since these units are connected by means of the subnetwork, any restriction is not given to spaces for installing the units. The capacities of the primary and secondary storage units and the transmitting buffer unit are selected so that they become larger in order of the secondary storage unit, the primary storage unit and the transmitting buffer unit. Thereby, the storage units and the transmitting buffer unit are controlled in a hierarchical form. This makes it possible to construct an AV sever system having large capacity and good responsivity with good cost balance.
