Title: A nickel based superalloy
Inventor: GRUBB KENNETH CHARLES
IPC: C30B29/52
Filed: 2006-05-03
Abstract: A nickel based single crystal superalloy comprising 7-9wt% cobalt, 3.5-4.5wt% chromium, 0-2.4wt% molybdenum, 4-8wt% tungsten, 3.5-6wt% rhenium, 5-6.5wt% aluminium, 6.5-8.5wt% tantalum, 0-0.2wt% hafnium and the balance nickel plus incidental impurities. The nickel based single crystal superalloy is suitable for use as a gas turbine engine turbine blade or turbine vane. It is of particular us on cooled turbine blades and turbine vanes which have ceramic thermal barrier coatings, because the superalloy is compatible with the ceramic thermal barrier coating to minimise spalling. The superalloy has better mechanical properties than other second-generation single crystal superalloys and has better creep strength and oxidation resistance.

Title: Method of scheduling resources in a communication system
Inventor: BREUER VOLKER
IPC: H04J13/00
Filed: 2006-10-23
Abstract: A method of scheduling resources in a communication system comprising a terminal, a base station and a higher level entity than the base station, where the method comprises allocating code space for users of a channel controlled by the base station and allocating the same code space for users of a channel controlled by the higher level entity. It is determined whether there is ongoing, or imminent higher level controlled communication in each part of the code space and for any part of the code space where there is no higher level controlled communication, that part of the code space is scheduled for base station controlled communication. The specific embodiment relates to a UTRAN FDD system, where orthogonal variable spreading factor (OVSF) codes (channelisation codes) need to be reserved for users in a CELL_DCH (dedicated channel) state (who use a base station controlled HS-DSCH channel) and for users in a CELL_FACH (non dedicated channel) state, (who use a use a RNC (higher level entity) controlled S-CCPCH channel). The code allocation and scheduling method of the invention addresses the problem that the code reserved for the S-CCPCH is used infrequently and would be useful for the code limited HS-DSCH. The method may also be used in UTRA TDD, TD-SCDMA and CDMA2000 systems.

Title: Interpolating irregularly sampled seismic data
Inventor: OZDEMIR AHMET KEMAL
IPC: G01V1/28
Filed: 2007-06-13
Abstract: A method of interpolating wave signals, particularly seismic signals acquired through a seismic survey, comprises obtaining 31 time series of measured wave signals and then iteratively selecting 33 basis functions to represent the measured signals. The basis functions are fully defined by n parameters. In each iteration one or more basis functions are combined with the selected basis functions such that the residual between the measured signals and a representation of the measured signal by the combined basis functions is minimized at the locations of the measurement at each iteration. The measured wave signals may be obtained at irregularly spaced locations or times. The basis functions may be sinusoids, and the parameters defining the basis functions may be amplitude, phase and frequency. The parameters of the basis functions may be determined using a matching pursuit optimization process. The interpolation method may be used in processing irregularly sampled seismic data to derive a representation of a subterranean reservoir.

Patent GB-2443343-A (GB)
Title: Noise tolerant voltage controlled oscillator
Inventor: SHANBHAG NARESH
IPC: H03B5/04
Filed: 2006-05-24
Abstract: A noise tolerant voltage controlled oscillator is described. The voltage controlled oscillator include a varactor element as part of an LC tank circuit. The varactor element is biased by a bias signal and a bias-dependent control signal. The bias-dependent control signal tunes the LC tank circuit. Because the control signal is bias-dependent, noise and other deleterious influences do not cause the varactor element to deviate in capacitance. Instead, the bias-dependent control signal is a tuning signal that is centered around the bias signal, which allows the varactor element to provide a constant capacitance in the event of a varying bias signal.

Abstract: A method and system for wireless communication channel estimation. A frequency offset hypothesis is determined. An interchannel interference ("ICI") matrix based on the frequency offset hypothesis is generated. Pilot channel estimates based on the ICI matrix are obtained. A correlation error of the pilot channel estimates to the frequency offset hypothesis is calculated. The correlation error is compared with a predetermined correlation error value. The frequency offset hypothesis is updated and the aforementioned steps are iteratively repeated if the correlation error is greater than the predetermined correlation error value. The pilot channel estimates are used to estimate the wireless communication channel.

Title: Power conditioning unit
Inventor: CUAUHTEMOC RODRIGUEZ
IPC: H02M3/315
Filed: 2006-01-13
Abstract: The present invention concerns a power conditioning unit for controlling the transfer of power from a dc energy source such as a solar panel, a fuel cell or a dc wind turbine, into an ac output. The ac output may be connected to the mains or grid utility supply, or used independently. The power conditioning unit comprises a dc-dc power converter 3 for receiving dc power, an energy storage capacitor 4, and a dc-ac power converter 5 for delivering ac power. Synchronised, independent control blocks 7, 8 control the system. The described method of control allows use of a smaller energy storage capacitor 4 than in prior systems. The capacitor 4 may have a value less than 20 microfarads. The energy storage capacitor 4 may thus be a non-electrolytic capacitor, such as a polyester or polypropylene capacitor, rather than a short lifetime aluminium electrolytic capacitor. Capacitor lifetimes of up to 500,000 hours can thus be achieved. The unit includes two control blocks. A first, power extraction control block 51 controls the dc-dc converter 3 to control power extracted from the dc power source and provided to the energy storage capacitor 4. A second, power injection control block 52 controls the dc-ac converter 5 to control power injected into the ac mains power supply from said energy storage capacitor.
