Title: Dual spatial integration for depth discrimination of heterogeneities in turbid media
Inventor: PAINCHAUD YVES
IPC: G01N21/47
Filed: 2000-01-21
Abstract: An improvement in a method for scanning a turbid medium for generating an image thereof for the detection of one or more anomalies contained within the turbid medium, the turbid medium having a first face and an opposite second face. In accordance with the method the turbid medium is scanned by displacing an optical signal source and a corresponding optical detector from one respective spatial location to another about the turbid medium, each spatial location being associated with a corresponding input region on said first face and a corresponding output region on the opposite second face. The optical signal source directs an optical signal to each of said input regions. The optical detector in response to optical signals detected from each of the output regions sends corresponding detector output signal data to an image processing means for generating a set of image data of the turbid medium. The improvement comprises generating in addition to a primary set of image data, secondary and/or tertiary image data which are derived by scanning the turbid medium using input regions and output regions of different sizes The various sets of image data obtained may be manipulated in any manner (i.e. subjected to a data processing technique) so as to for example highlight the differences or similarities between the images (e.g.. to obtain a composite set of image data indicative of an anomaly(ies) in the body of the turbid medium).

Title: Wellhead isolation tool and method of using same
Inventor: DALLAS L MURRAY
IPC: E21B33/068
Filed: 2000-02-28
Abstract: A wellhead isolation tool permitting a high fluid flow rate during a well treatment to stimulate production is described. The wellhead isolation tool includes a mandrel to be inserted into a wellhead. The mandrel is sealed in a tubing hanger above back pressure valve threads to isolate the pressure sensitive components of the wellhead from fluid pressure used in the well treatment, and has a lower section extending past the back pressure valve threads and tubing threads into the tubing to protect the threads from washout. The mandrel is locked down with a mechanical lockdown mechanism having a broad range of adjustment. The advantages are that no special tubing hanger is required for use with the mandrel, and a fluid flow rate enabled by the tool during the well treatment is significantly higher than a fluid flow rate enabled with conventional wellhead isolation tools.

Title: Gas turbine starting method
Inventor: ARIMURA HISATO
IPC: F04D27/02
Filed: 2000-03-14
Abstract: The start operation of the gas turbine starting method is improved with bleed valves being first throttled, then fully opened and then fully closed at 90% speed, thereby fluid unstableness phenomenon is suppressed and starter motor power is reduced. While inlet guide vane (11) and variable stator vanes (C1 to C5) are opened to predetermined settings from starting to rated speed, bleed valves (1, 2, 3) are open to a predetermined setting until speed is elevated to 52% for the bleed valve (1) and until a speed is elevated to 51% each for the bleed valves (2, 3). Then the bleed valves (1, 2, 3) are fully opened until the speed exceeds 90%, when they are fully closed for rated operation. In the prior art, the starting operation is done with bleed valves being first fully opened until the speed is elevated to 90% and then fully closed. In the present invention, the air discharged into the ambient air can be reduced and thereby starter motor power can be also reduced.

Inventor: REGE KIRAN M
IPC: H04L45/122
Filed: 2000-12-22
Abstract: In an ad-hoc mobile network, a geometry-based routing protocol (GRP) is used to route traffic from a source node to a destination node. In order for GRP to be effective, the network needs to have certain routability characteristics. To that end, each node collects location information from surrounding nodes and uses the collected location information to select those surrounding nodes that facilitate geometric routing and sets up point-to-point links with the selected nodes (becoming direct neighbors). The node then constructs its k-neighborhood, (where the value of k represents the maximum number of hops needed to reach any node in the desired local topology) by exchanging its list of direct neighbor nodes with other nodes.

Abstract: An explicit rate ABR algorithm for use in an ATM switch. The available bandwidth for ABR connections (Abw) is determined after guaranteed traffic is served (step 102). The per-VC fair share of Abw is calculated in two different ways depending on whether the VC is congested. Where the VC is not congested, the fair share is calculated by dividing the Abw by an averaged number of currently active ABR connections (step 112). Where the VC is congested, the fair share is calculated by dividing the Abw by the number of currently established ABR connections (step 106) and reducing the fair share by damping factor (damp(x)) which is a function of the VC's queue length. A new explicit rate (ERnew) is determined by adding the fair share to the minimum-cell-rate (MCR) (steps 108, 114). The ERnew replaces the old explicit rate (ER) only if it is lower than the ER (step 120).
