Patent GB-2418825-A (GB)
Title: Coupling network for a power line modem
Inventor: LAW ROBINSON PENG SENG
IPC: H04B3/56
Filed: 2005-08-11
Abstract: A coupling network (190) has a first power line interface port and a power line modem interface (191) configured to be coupled to a power line modem transceiver (192). An inductor-capacitor (194-198) circuit coupled to the power line modem interface (191) has a low-impedance resonant frequency at a signal frequency of the power line modem transceiver (192). An inductor (200) having a corner frequency between the signal frequency and the power line frequency has a first end and a second end. The first end of the inductor (200) is connected to the inductor-capacitor circuit and a second end of the inductor is coupled to an alternating current ground coupled to the transceiver ground. The inductor (200) couples the first power line interface port to a power supply interface port. As the inductor has a corner frequency between the signal and power line frequency, the coupling network appears to be in series with the power line and hence a larger EMI (Electro Magnetic Interference) capacitor can be used without affecting the impedance of the load.

Title: Variable delay circuit
Inventor: SAWYER DAVID ALBERT
IPC: H03L7/081
Filed: 2005-08-23
Abstract: A variable delay circuit (13, 27-30) is provided for delaying an input signal by a selectable variable time delay. The circuit comprises a selecting arrangement (21) for selecting how many of a first group (13) of delay elements (20) are connected in series for delaying an input signal. Identical delay elements (26) are connected in series to form a second group. A measuring circuit (27) repeatedly measures the delay provided by the second group, for example providing output pulses (IP) whose width or duration is equal to the delay. A reference pulse generator (29, 30) generates a series of reference pulses (IR), each of which is of a predetermined duration. A control circuit, such as a charge pump and integrator (28), compares the measurement pulses (IP) and the reference pulses (IR) to generate an error signal which is fed back to timing delay control inputs of all of the delay elements (20) such that the widths of the measurement and reference pulses (IP, IR) are made substantially equal to each other. Has uses in optical disk writers and tuners.

Title: Monitoring performance of a communications network
Inventor: BOND DAVID
IPC: H04W24/00
Filed: 2005-11-30
Abstract: Mobile terminals within a communication network are used to measure a parameter of network performance and transmit data, including the position of the terminal, to a remote processor for building a database of locations versus service parameters. A mobile terminal 110 measures its own position e.g. via GPS. A software agent in the mobile terminal measures a parameter of the communication network e.g. signal strength received from a base station 114 and transmits its position and the measured parameter to a remote processor 108. The processor collects information from many mobile terminals and builds a database 106 relating network service parameters to locations. The network parameters measured may also be e.g. data download or upload rates for a data service. The invention provides an alternative to conventional drive testing.

Title: Power factor pre-regulation stage for power converter
Inventor: YOUNG GEORGE
IPC: H02M1/00
Filed: 2006-03-10
Abstract: A power converter comprises a power factor pre-regulation stage 5, an isolation stage 7 and a control unit 9. The power factor pre-regulation stage comprises a buck power factor correction (PFC) circuit implemented using low side driver switch 19, low side current sensing and a bulk storage capacitor 25. Controller 9 measures parameters of the converter circuit and causes the buck PFC circuit to provide additional current to storage capacitor 25 in response. Additional current may be supplied by increasing the loop gain of a feedback circuit 33,35,37, and may be accomplished by changing the value of an input resistance to the feedback circuit using switch 33. Measured circuit parameters may include the voltage across bulk capacitor 25, which may be compared to a threshold, additional current being supplied to capacitor 25 when the capacitor voltage is below the threshold. Measured circuit parameters may also include the current in the isolation stage output, which may be filtered, allowing the current to be increased to the capacitor 25 in response to transient load conditions.

Title: Compensating the drift of a local clock in a data acquisition apparatus
Inventor: LAINE JEROME
IPC: G01V1/32
Filed: 2006-07-27
Abstract: A data acquisition apparatus, especially a node of a wireless seismic data acquisition network, comprises an analog/digital converter 510 sampling the data acquired by a sensor 500 at an imperfect frequency provided by a local clock 100. A time-stamping module 300 measures the frequency error of the local clock 100 by determining the sampling dates according to a universal time UTC(t). The time-stamping module 300 gauges the local clock to a reference clock of a satellite-based positioning system 200. The satellite-based positioning system is turned off once gauging of the local clock has been performed. A resampling module 400 corrects the sampled data. The device allows use of an inexpensive local clock. Since it is unnecessary to have the satellite-based positioning system turned on for the duration of the data acquisition energy consumption is minimised.

Inventor: ANGELESCU DAN EUGENE
IPC: G01F1/7084
Filed: 2006-08-29
Abstract: A method and apparatus for measuring a parameter of a fluid within a fluid channel 100 is described. The parameter may be the flow rate or flow composition. The time of flight of a tracer element between an injection location 108 and a detection location 110 is determined by cross correlating data derived from the injection element and the detection element.

The apparatus is suitable for single phase flows or mult-phase flows. The flow channel may be a micro fluidic channel, a flow line in a downhole tool, or a flow passage in a production logging environment. If the tracer element is a thermal marker a MEMS heating device may be used.

Title: Silica-based chromatographic stationary phase
Inventor: CHEN WU
IPC: B01J20/281
Filed: 2007-03-06
Abstract: A chromatographic stationary phase, for reversed-phase high performance liquid chromatography (HPLC), and process for forming is disclosed which comprises a silica support having bonded via an Si-O bond a silane coupling agent of the formula OSiR<1>R<2>R<3>. where R<1>, R<2>, R<3> are independently hydrogen or C1 to C30 hydrocarbyl provided that at least one is a C4 hydrocarbyl or higher, and bonded via an Si-O bond or bonds an end-capping silane selected from either OSiHCH4R4 and OOSiHCH3 where R<4> is hydrogen or methyl. The silanising agents used may have halogens, alkoxy or aminoalkyl groups as leaving groups. The agents also may include silazanes. The treatments may be carried out in an inert solvent under reflux and in the presence of an acid scavenger. By using mono and dimethyl silanes as endcapping reagents as compared with the use of traditional trimethyl silanes, an improved blocking of unreacted surface silanols is achieved. The improved blocking of surface silanols results in at least better peak shape and more reproducible retention times in reversed-phase HPLC analyses.
