Title: Communications receiver data processing for quadrature modulated data
Inventor: REEVE JOHN MICHAEL
IPC: H04L27/38
Filed: 2001-11-22
Abstract: A data processing circuit for a communications receiver. In operation, input samples (e.g. from an ADC) are fed at a clock rate to an input of the sign modifying module 29. The sign modifying module 29 acts to modify the sign of the value of pairs of incoming samples in accordance with a control signal from the control module 27. The output of the sign modifying module 29 splits into two paths 30a, 30b. The first path 30a includes the delay elements 31, 33 and the multiplying means 35. The second path 30b includes the multiplying means 37. In the first path 30a, samples outputted from the sign modifying module are delayed by two clock periods by the delay elements 31, 33. The multiplying means 35, 37 are arranged to multiply applied input samples by one of two different weighting factors. Finally, the outputted samples from the first and second multiplying means 35, 37 are each fed to the summing module 39 whereby the value of the output samples are added together. The circuit is preferably applied to IQ modulated data and performs IQ separation, filtering, down conversion by   of the clock rate and decimation by 2. (See equivalent circuit Fig. 1).

IPC: E21B33/14
Filed: 2002-04-24
Abstract: An apparatus for the completion of wells through a production tubing comprises a tool body 32 having cement flow ports 58, 60 and pressure displaced port-closure piston valves 50, 52. A perforated mandrel tube 34 concentrically aligned within the tool body is secured to the tool body at its upper end. Concentrically within the mandrel tube 34 is a dart transport tube 36. The dart transport tube is releasably secured to the tool body by a set of locking dogs 68. A first dart plug (100, figure 6) is placed in the production tubing bore at the well surface to be pumped or allowed to gravitate onto a closure seat 92 in the lower end of the of the transport tube 36. This seat closure allows the production tubing to be pressurized for setting well annulus packers 18 and opening of a port closure piston 52. After the production tube has been set by cement pumped down the production tubing bore and through the cement flow port 58, a second dart plug (102, figure 7) is positioned atop the cement column in the production tube. A pumped column of water or other well working fluid sweeps most of the production tube cement column into the well annulus and lower end of the transport tube 36. The second dart plug lands against an upper bore seat 85 in the transport tube to enable another pressure increase in the production tube fluid column. This next pressure increase shifts a sleeve piston 50 that closes the cement flow ports 58, 60 and releases the transport tube locking dogs 68. With the locking dogs released, the transport tube 36 falls through the mandrel tube 34 and removes residual cement.

Title: Filter arrangement in a multi-band mobile terminal device
Inventor: PORTIN JYRKI
IPC: H03H9/64
Filed: 2003-03-28
Abstract: A terminal device (90, fig. 1) for mobile communications networks may operate in frequency bands such as 800MHZ for GSM, 1800MHZ for DCS, or 1900MHZ for PCS services. The receiver of the terminal device 90 includes at least two bandpass filters 21, 22, the overlapping passbands of which are further bandpass filtered by a third bandpass filter 40. Filter 40 may be a ceramic filter with good frequency stability. Because the edges of the passband 40a of the bandpass filter 40 are steep, the filters 21, 22 can be implemented using surface acoustic wave (SAW) filters, whose passbands may be less stable in response to temperature changes. The arrangement minimises filter costs as the final passband is determined by the passband of only the filter 40.

Title: Route discovery with quality of service check in ad hoc network
Inventor: FAN ZHONG
IPC: H04L47/724
Filed: 2004-02-27
Abstract: The invention provides a method of admission control at an intermediate node between a source node 20 and a destination node 90 in an ad hoc network, e.g. a wireless ad hoc network, preferably a mobile ad hoc network (MANET). The source node 20 sends a route request message including quality of service requirement information to discover at least one route to a destination node 90 via one or more intermediate nodes 30, 40, 50, 60, 70. The destination node 90 then generates for at least one discovered route between the source node 20 and the destination node 90, a route reply message which includes the quality of service requirement information. The route reply message is sent to the source node 20 via the intermediate nodes defined in the discovered route (e.g. 50, 60). On receipt of a route reply message, each intermediate node determines whether it can meet the requirements specified by the quality of service requirement information and, if so, transmits the route reply message to the next node in the route; the node does not forward the route reply message if it determines that it cannot meet the requirement. Thus the source node 20 only receives replies from discovered routes which have recently determined that they satisfy the quality of service requirement information, which is advantageous in highly mobile ad hoc networks where up-to-date information is essential. A similar determination based on the forward transmission of the route request message (see fig. 2) may be used to ensure the destination node 90 only replies along routes that meet the quality requirements. The quality of service requirement determination may be based on more than one quality metric, e.g. the maximum available bandwidth at a node may vary depending on a MAC delay (fig. 5).

Title: Selecting operational parameters in a communication network
Inventor: RASHMI MISRA
IPC: H04Q7/32
Filed: 2004-03-18
Abstract: The present invention provides a method of selecting operational parameters of a communication network. The method is characterised by searching the operational parameter space using a multiple objective simulated annealing (MOSA) process, wherein the objectives are based upon performance indicators (PIs) of the communication network. Moreover, the MOSA process generates an archive of estimated values of a Pareto front, and employs a dominance-based energy function. The present invention thus provides the benefit of enabling assessment of different estimated optimal trade-offs between multiple objectives.
