IPC: H04L12/721
Filed: 2000-04-17
Abstract: The present invention relates to an Explicit Routing Method used in a packet-based network containing a number of network-nodes, source-nodes and destination-nodes. All before mentioned network elements are interconnected by links. This method is used to route a packet-flow from a source node towards a destination node, along an explicit path through a number of these network-nodes.     This method includes the step of determination of the explicit path of the packet-flow between the source-node and the destination-node. A subsequent step is the determination of the relevant intermediate network-nodes situated on the explicit path which are necessary to deviate said packet-flow from a hop-by-hop-path onto said explicit path and further adding only addresses of these relevant intermediate network-nodes to the packets of the packet-flow. A following step is forwarding the packet-flow from the source-node towards the destination-node in direction of the explicit path.

Title: Methods and devices for cannulating a patient's blood vessel
Inventor: DONLON BRIAN S
IPC: A61M25/08
Filed: 1998-11-05
Abstract: This invention is a method, a device for introduction of a catheter (6C), and/or delivering a fluid, such as oxygenated blood, to a patient's vascular system including a cannula (2C) having an expandable portion (4C). The expandable portion (4C) is movable from a collapsed position to an expanded position. The expandable portion (4C) is inserted into the patient in the collapsed position which facilitates introduction and advancement of the cannula (2C) through the patient's blood vessel. After introduction into the patient, the expandable portion (4C) is moved to the expanded position. The expandable portion (4C) protects the blood vessel against fluid forces when flowing a fluid through the cannula (2C), and protects the vessel from contact with the catheter (6C) advanced through the cannula (2C).

Title: Electrodialysis water splitting process
Inventor: MANI KRISHNAMURTHY N
IPC: C25B7/00
Filed: 2000-08-03
Abstract: An electrodialysis water splitting processes incorporates a chromatographic separation step using an amphoteric ion exchange resin to remove contamination salts from a salt solution feedstream and a base product solution. When the chromatographic column is subsequently eluted with water an effective separation of the components is achieved. The separated pure salt stream is forwarded to an electrodialysis water splitter cell for conversion to acid and base. The base product solution (sodium hydroxide, potassium hydroxide) may be similarly purified by passing through a second chromatographic column also containing an amphoteric resin to separate the base from the salt (recovered salt). The process is also applicable in a chlor-alkali process for acidifying the brine feed to the electrolysis cell and for producing high purity caustic from salt.

Abstract: A jitter control system is provided for determining display latency and simultaneously reducing audio gaps in received voice packets. Three methods are set forth for estimating the mean delay and delay variation for the voice packets from collected measurements . Based on these estimations, a Gaussian delay distribution is built for the packet arrival. Then, probabilities for single gap and multiple contiguous gaps for a given display delay are calculated and the packet is played out. Hence, the display delay can be dynamically adjusted according to recent delay characteristics and tradeoff policy between gap frequency and display latency.

IPC: E06B9/262
Filed: 2001-04-12
Abstract: An architectural covering, such as a blind, for use primarily over windows and doorways, includes of a plurality of separate composite vanes made of an opaque rigid material and a sheer material, if desired. Each composite vane can be manufactured as a flat, rollable laminated assembly of strips and joined or bonded at least substantially on a line along the length of the strip and substantially along one edge of one strip. Several different embodiments of the composite vane are disclosed. In one embodiment, the composite vane comprises a generally flat, unexpanded opaque material with individual pieces of sheer material attached to an edge of the vane. In another embodiment, a laminated composite vane comprises a pair of strips with the transverse width of one strip greater than the other strip to form a torque tube when edge-joining the strips. In yet another embodiment, the laminated composite vane includes a pair of strips of substantially equal width with a resilient insert strip having a non-flat cross section inserted into the torque tube. The resilient insert strip can assume a flat transverse form, but return elastically to the predetermined cross-sectional shape when removed from the roll or be inserted after each vane is cut to its final length. Any combination of the above-mentioned embodiments is possible to connect single or double sheets of sheer material to the edges of the vanes while enabling the vanes to be oriented vertically or horizontally.

Title: Method and apparatus for preventing scaling in electrodeionization units
Inventor: BARBER JOHN H
IPC: C02F1/42
Filed: 1999-09-24
Abstract: A method and apparatus is provided for inhibiting scaling in an electrodeionization system and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit by inhibiting precipitation of scale-forming metallic cations contained in the feed water and thereby increasing efficiencies of the electrodeionization system. Water  to be purified is passed through an electrodeionization unit in which the fl ow in the diluting compartment is countercurrent to the flow in the concentrati ng compartment. This is to impede the migration of scale-forming metallic catio ns from the diluting compartment, through the cation exchange membrane, into th e concentrating compartment and towards the concentrating compartment side of the anion exchange membrane, thereby preventing scale formation on the anion  exchange membrane. The electrodeionization unit may be further modified by dividing the concentrating compartments into first and second compartments b y a porous diaphragm or ion-conducting membrane. The porous diaphragm or ion- conducting membrane effectively eliminates convective transport of scale- forming metallic cations from the cation exchange membrane side of the concentrating compartment to the anion exchange membrane side of the concentrating compartment, thereby inhibiting scale formation on the anion exchange membrane.

Title: Non-uniform memory access (numa) data processing system that speculatively forwards a read request to a remote processing node
Inventor: BAUMGARTNER YOANNA
IPC: G06F12/08
Filed: 1999-12-10
Abstract: A non-uniform memory access (NUMA) computer system includes at least a local processing node and a remote processing node that are each coupled to a node interconnect. The local processing node includes a local interconnect, a processor and a system memory coupled to the local inteconnect, and a node controller interposed between the local interconnect and the node interconnect. In responce to receipt of a read request from the local interconnect, the node controller speculatively transmits the read request to the remote processing node via the node interconnect. Thereafter, in response to receipt of a response to the read request from the remote processing node, the node controller handles the response in accordance with a resolution of the read request at the local processing node. For example, in one processing scenario, data contained in the response received from the remote processing node is discarded by the node controller if the read request received a Modified Intervention coherency response at the local processing node.
