Abstract: An intraluminal catheter (24) for directing a guidewire (26) and/or catheter (26a) in a desired direction within a bodily vessel or cavity. The intraluminal catheter (24) has a first elongate tubular member (52) and a support means which can comprise a second elongate tubular member (51) that can pass over a main support guidewire (23). The catheter (24) acts as a platform as the guidewire (26) is passed through the first elongate tubular member (52) and is deflected transversely outwardly by an angled surface (54) through an aperture (50). A  second intraluminal catheter (60) has a first elongate tubular member (63) and a support means comprising a second elongate tubular member (61). The first elongate tubular member (63) has a main portion (65) and an end portion (66), with the end portion (66) being deflectable relative to the locus of the main portion so as to direct the guidewire (26) passing through the end portion (66) in a desired direction in the bodily vessel.

Abstract: A control unit and a related method of operation for controlling the temperature of the water circulated in the radiant loop of a hydronic heating system. The control unit includes temperature setting dials that can be used to adjusts the reset curve used to determine the desired secondary, radiant loop water temperature.  The control unit generates a linear reset curve between two setpoints such that the control unit can calculate a desired secondary loop water temperature based on the reset curve and the present outdoor air temperature. The control unit monitors the temperature of the water returning to the boiler from both the primary loop and the secondary, radiant loop. The control unit monitors the return water temperature over a first interval and, based on the rate of change in the return water temperature, calculates a predicted return water temperature at a second interval in the future. If the predicted return water temperature is lower than the user-selected minimum return water temperature, the control unit operates the modulating valve to reduce the amount of heated water flowing to the secondary, radiant loop.

Abstract: Within the field of integrated circuits used in amplifiers, a structure and improved method for calibrating a switched capacitor gain stage wherein the time required to self-calibrate a switched capacitor gain stage and the associated structure are reduced. The invention utilizes only a single calibration step which is performed while the output of the amplifier being calibrated is monitored. Instead of utilizing a plurality of capacitors C a1 - C an each in parallel with groups of trim capacitors C T, a single capacitor C a is used and connected to switches S1a1 and S1b1. Further, instead of a group of trim capacitors C T being connected in parallel with the capacitor to be trimmed, each of plurality of trim capacitors C T1 - C TM is connected between the input to the operational amplifier and a respective corresponding switch S1a2 - S1aN to the input reference voltage node V b0. As well, switches S1b2 - S1bn connect the respective junctions between the trim capacitors C T1 - C TM to ground.

Granted: 2008-08-05
Abstract: Méthode de migration avant sommation (« prestack migration ») permettant d'imager une zone souterraine, pour un modèle de vitesses donné de complexité arbitraire. - Au moyen d'outils classiques de modélisation de la propagation et de la rétropropagation des ondes, la méthode permet d'obtenir des images migrées élémentaires associées aux valeurs que prend un paramètre et la somme des images obtenues pour les différentes valeurs du paramètre (sommation après migratio n) et ceci aussi bien dans le domaine profondeur que dans le domaine temps. Cette migration est obtenue à un prix (coût de calcul) avantageux car indépendant du volume de résultats calculé et du nombre de traces sismiques enregistrées. Seul le volume de la zone dans lequel les ondes se propagent, la complexité des événements à imager et la précision souhaitée ont une incidence sur le coût du calcul. On obtient ainsi des imag es volumiques en prenant en compte l'ensemble des traces sismiques. On a ainsi la possibilité de mettre en oeuvre une procédure de migration par ondes planes dans le cas où l'acquisition ne permet pas la synthèse de la réponse de la subsurface à une excitation onde plane, réponse requise en entrée dans les algorithmes classiques de migration par ondes planes. - Applications à l'imagerie d'interfaces géologiques ou hétérogénéités d'une partie de zone souterraine.

Title: Method and apparatus for supplying requests to a scheduler in an input-buffered multiport switch
Inventor: BAUMAN JAMES A
IPC: H04L12/56
Filed: 1999-04-29
Granted: 2004-10-19
Abstract: A method and apparatus for supplying new requests to a scheduler (132) in an input-buffered multiport switch involve selecting a request that does not target output channels that conflict with output channels targeted by requests (282) that are already accessible to the scheduler. Specifically, target output channels of requests that are presently accessible to the scheduler are identified (362) and compared to target output channels of requests that are included in a queue of next-in-line requests. The queue of next-in-line requests is reviewed (364) and the highest priority request having no conflicting output channels is supplied to the scheduler. By supplying the scheduler with a new request that targets non-conflicting output channels, the scheduler is presented with a wider range of requested output channels from which to choose in each arbitration cycle. In a first embodiment, one, two, or eight ports are connected to each one of four input/output controllers (242, 244, 246, and 248) in a switch having a four-channel switch fabric. To supply the scheduler with new requests, secondary arbitration is performed on a channel-specific basis in order to supply channel-specific requests to the scheduler. The method of supplying requests to the scheduler can be scaled to include multiple channels and multiple packet priority designations.

Abstract: A buff is made from a non-woven fabric; where the fibers are first carded and formed into a fairly thick fleece. The fleece is passed over a topographical surface on, for example, a moving belt or a drum. The fleece is subject to a bow-tie hydroentanglement process where: many fine jets of water entangle the fibers on the topographical surface. Excess water is vacuumed from the system. The fabric is dried and chemically treated. With the fabric a variety of buffing tools are made, in wheel, belt or roll form. Tests against standard and mill treatment buffs show a remarkably lower fabric weight loss percentage and lower or normal operating temperatures. The fabric has exceptional mechanical strength, having a tensile strength in excess of 650 N/50 mm according to DIN 29073/3. preferably the fabric has a tensile strength of at least 1,000 N/50 mm in the machine direction and in excess of 900 N/50 mm in the cross direction according to such DIN.
