Abstract: An optical single-sideband modulated signal generator, comprising optical modulation means for amplitude-modulating an optical carrier by an electric modulation signal to obtain an optical double-sideband modulated signal, and optical signal sideband suppressor means for suppressing either one of the sidebands of the optical double-sideband modulated signal to derive therefrom an optical single-sideband modulated signal. The optical modulation means provides, respectively, first optical double-sideband modulated signal and second optical double-sideband modulated signal on branched optical waveguide paths, which have at least one optical carrier phase-shifter for establishing a relative phase difference of 90° between baseband signal components at the branched optical waveguide paths and at least one delay means for compensation for a relative delay difference between the baseband signal components at the branched optical waveguide paths.

Granted: 2006-12-19
Abstract: A controller (208) in a communication device (106) receives a request, from a process operating in the communication device (106), to subscribe to a data routing service that is managed by the controller (208). In response to the request, the controller (208) assigns a destination identifier to the process and adds the process and the assigned destination identifier to a routing table that is stored in a memory (212) associated with the controller (208). Data subsequently received from a data source (114) is routed to the process or to one of multiple communication ports (214, 216, 218) by the controller (208) by reference to the destination identifier, or the absence of a destination identifier, stored in the routing table.

Abstract: Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed. Using the teaching of the present disclosure, a surgeon can customize a fastener to the particular surgery or even to the particular portion of surgery being performed during the surgery.

Abstract: Flow rate measurement system includes two measurement regions (14, 16) located an average axial distance .DELTA.X apart along the pipe (12), the first measurement region (14) having two unsteady pressure sensors (18, 20), located a distance X1 apart, and the second measurement region (16), having two other unsteady pressure sensors (22, 24), located a distance X2 apart, each capable of measuring the unsteady pressure in the pipe (12). Signals from each pair of pressure sensors (18, 20) and (22, 24) are differenced by summers (44, 54), respectively, to form spatial wavelength filters (33, 35), respectively. Each spatial filter (33, 35) filters out acoustic pressure disturbances Pacoustic and other long wavelength pressure disturbances in the pipe (12) and passes short-wavelength low-frequency vortical pressure disturbances Pvortical associated with the vortical flow field (15). The spatial filters (33, 35) provide signals Pas1, Pas2 to band pass filterS (46, 56) that filter out high frequency signals. The Pvortical-dominated filtered signals Pasf1, Pasf2 from the two regions (14, 16) are cross-correlated by Cross-Correlation Logic (50) to determine a time delay ~ between the two sensing locations (14, 16) which is divided into the distance .DELTA.X to obtain a convection velocity Uc(t) that is related to an average flow rate of the fluid (i.e., one or more liquids and/or gases) flowing in the pipe (12). The invention may also be configured to detect the velocity of any desired inhomogeneous pressure field in the flow.

Abstract: A papermaking press felt having excellent rewetting suppression without impaired water-squeezing capability.  comprises a base body, batt layers, and a rewetting prevention layer, integrated with one another by needle punching. The rewetting prevention layer has three dimensional passages comprising a verge opening, a wet paper web side opening and a roll side opening. The wet paper web side opening is larger than the roll side opening. Under nip pressure, water from the wet paper web moves into the roll surface side of the felt, passing through the passages in the rewetting prevention layer.  Although a rewetting phenomenon tends to occur when the press felt is released from the nip pressure, movement of water through the passages back to the wet paper web side of the felt is suppressed since the roll side openings are narrower than the wet paper web side opening.

Abstract: A flexible guide for a door includes straps that are mounted in pairs along either side of a doorway. As the door opens and closes, the straps guide the vertical movement of a door panel that travels within the channel. The strap s are pulled in tension between upper and lower anchors to provide the straps with enough stiffness to effectively hold the door panel within the channel under normal operation. In some embodiments, springs are used to maintain th e tension in the straps. The straps are also sufficiently pliable and resilien t to allow an impact to dislodge the door panel out from within the channel without damage. The upper or lower anchor is moveable between a normally extended position and a yielded position to prevent an impact from breaking the anchor and may further be biased to the normal position.

Inventor: BAI YU SHENG
IPC: H04B10/18
Filed: 2001-08-10
Granted: 2011-03-29
Abstract: A system and method for transmission of data modulated spectrally enriched optical pulses via an error free propagation region of an optical fiber, in which the optical pulses generated by an optical transmitter have a spectrum that is substantially wider than the spectrum of Fourier-transform limit at an input of the error-free propagation region. The spectral width of the optical pulses gradually narrows while transmitting along this regions and becomes comparable to the Fourier-transform limit at an output of this region. Linear and non-linear distortions are compensated within the error free propagation region respectively by deployment of dispersion compensating units and phase modulation of transmitted optical pulses for providing them with an appropriate frequency chirp having shape comparable with a frequency chirp induced by a self-phase modulation of the optical fiber but having opposite sign.

Abstract: La présente invention concerne un procédé et un appareil d'affectation adaptative de porteuses pilotes dans un système de communication à accès multiple par répartition en fréquence (OFDMA). Pour améliorer la performance d'estimation d'erreur de phase et optimiser le nombre de porteuses pilotes affectées à chaque sous-voie, un émetteur OFDMA change le nombre de porteuses pilotes pour une sous-voie en fonction de l'état de la sous-voie. Par conséquent, moins de porteuses pilotes sont affectées à une sous-voie en bon état, ce qui réduit la consommation de puissance et plus de porteuses pilotes sont affectées à une sous-voie en mauvais état, ce qui améliore la performance d'estimation des voies malgré une consommation de puissance accrue.
