Abstract: A subscriber database, in at least one embodiment, stores RF level and timing advance information associated with all mobile telephones on a network. A location parameters database stores location data that associates different physical locations with RF levels/timing advance data that have been measured or inferred for those locations. The subscriber database is then interpreted for the purpose of establishing the location of a specific mobile telephone at a given time by matching the RF level/timing advance data for that specific mobile telephone against the location parameters database. This generates the location of the mobile telephone. The interpretation or querying of the subscriber database only occurs, however, when there is a request to establish the location of a specific mobile telephone, and not as an automated process applied to all mobile telephones on a network.

Abstract: A system and method facilitates the analysis and sampling of well fluid. A sampling and data collection device is used to detect well fluid properties in situ at a flowline installation. In an exemplary embodiment, the sampling and data collection device comprises a sample collection system having a probe adapted to selectively insert into and selectively retract from the flowline to collect a fluid sample, and a sensor system to determine PVT data in situ at the location where the probe is inserted into the flowline.

Abstract: An apparatus and method for selectively capturing substantially separate phases from a multiphase fluid mixture flowing through a flowline. The apparatus is preferably substantially aerofoil shaped, and includes sample ports which are positioned on the apparatus in such an orientation that takes advantage of the low density and high density flow around the aerofoil shape, as well as the pressure distribution around the aerofoil shape.

Abstract: A system, method, and fluid analysis module are provided for the real-time analysis of multiphase fluids. The system generally comprises means for directing a fluid stream from a flow line to a fluid analysis module, a processor and communication means. The fluid analysis module comprises sensor for measurement of at least one property of the fluid. The processor processes the measurement data from the sensor, and the communication means communicates the processed data to a central acquisition unit or computer.

Abstract: A method of processing positioning data to create map data is disclosed, the map data including a plurality of navigable segments representing segments of a navigable route in the area covered by the map with each segment being arranged to have speed data associated therewith. In at least one embodiment, the method includes processing the speed data to categorise the speed data into a plurality of time periods for the navigable segment with which the speed data is associated; and averaging the speed data within each time period in order to generate a measured speed profile for the navigable segment.

Abstract: A dump bailer is disclosed herein comprising a tool body defining a chamber for containing a material to be deposited and an outlet in the tool body through which the material can be deposited. The dump bailer also comprises a piston assembly slideably mounted in the chamber and comprising a swabbing piston, a supply of pressurized fluid, and a valve for releasing the pressurized fluid to act on the swabbing piston to drive it along the chamber to expel material contained therein through the outlet.

Abstract: The present invention relates to a method for monitoring vehicular traffic flow in a road network (1) in an area served by a mobile telecommunications device network (7) having a call management system (10) provided with a mobile telecommunications device positioning system (11) providing positional data for active mobile telecommunications devices (12). The method comprises capturing geographical positioning data for individual active devices carried aboard vehicles (12) and converting these into probability vectors representing the likelihood of the vehicle having arrived at any of the possible road components (16) of the road network (7) compatible with the geographical positional data. As the vehicle (12) travels along, this process is repeated and new probability vectors constructed based on the probability of any of the available routes between the new probability vector mad component position and the immediately preceding probability vector road component position.

Abstract: The present invention relates to an Asynchronous Transfer Mode (ATM) network, and in particular to a system and a method for a number of ATM devices to share the facilities provided by a single ATM switch port. An ATM switch has a number of switch ports which may receive and transmit the data comprising information and a routing identifier. A number of ATM devices are connected in series to each other in a device chain, and at the ends to the chain to a first ATM port. The devices are adapted to distinguish between the information and the routing identifier and may receive and transmit information through the chain, with a first or head device receiving data from the ATM port and the last device transmitting data to the ATM port. A control computer is connected to a second ATM port and may be programmed with the identities of the ATM devices and communicate through the first switch port with a device in the device chain.
