Title: Multicarrier modulated signal receiver which cancels impulse noise using an estimate derived from the equalised signal
Inventor: ZHIDKOV SERGEY
IPC: H04J11/00
Filed: 2004-07-22
Abstract: The receiver recreates a version of the transmitted signal (314) from the equalised (304) frequency domain version of the signal, post fourier transform (302). This is subtracted (316) from the equalised signal to give a total noise signal, which is returned to the time domain, by IFFT (322), where noise peaks representing the impulses are detected (326). These peaks are returned to the time domain, by FFT (328) and finally subtracted from the equalised received signal (338) to cancel the impulse noise. The system improves over prior art clipping arrangements in that impulse noise which does not increase the magnitude of the signal beyond its normal range can be can be cancelled. The system is usable with modulation schemes such as OFDM. The impulse noise cancellation can be applied repeatedly to improve the compensation (see Fig. 10).

Title: Pilot valve for steam turbine
Inventor: PADFIELD ROGER
IPC: F01D17/14
Filed: 2005-03-31
Abstract: A pilot valve (31) associated with a main valve (32) for the admission of steam to a steam turbine comprises convergent-divergent nozzle (47) formed by a concave deflector (35) that is part of the pilot valve head (33) and a convex portion of the pilot valve seat (34).

Title: Device with multiple One-Time Pads having different security tings
Inventor: HARRISON KEITH ALEXANDER
IPC: H04L9/08
Filed: 2005-10-31
Abstract: A device (10) is arranged to carry out security-related tasks using one-time pad (OTP) data. The device (10) has a memory (13) for holding multiple one-time pads (31-33), each pad having a different security rating and being intended for use by the device (10) in executing a task to that security rating. Provisioning of the pads (31-33) with one-time pad data involves carrying out a process for obtaining new secret random data. This process has a security rating with the value of this rating varying according to the nature and parameters of the process concerned. The security rating of the process used to obtain the new secret random data is matched to that of the pad to be provisioned with one-time data, or the other way around, such that the security rating of the process is as least as good as that of the pad to be provisioned. For example, a high security process uses a trusted wired interface, a medium security process uses an infra-red interface, and a lower security process uses a radio interface. The secret random data may be generated using quantum key cryptography (QKD).

Title: Regulating the output of a switch mode power supply
Inventor: GARNER DAVID MICHAEL
IPC: H02M3/335
Filed: 2006-05-23
Abstract: A switch mode power supply (SMPS) output voltage is regulated using primary side sensing of a magnetic energy storage device such as transformer 1. An integrator 6 integrates the difference between a feedback signal from a winding 4 and first reference Vref1 and the result is compared with second reference Vref2 in a comparator 7 whose output is then used to regulate the output. The reference levels may be set so that the output of comparator 7 may control sample-hold circuit 12,13 to sample the feedback signal at a time when the flux in the storage device is zero and may also control a second integrator (fig 4) that integrates the feedback signal when the flux is zero. Integrator 6 may begin integrating and be reset in response to a switch 5 control signal. The circuit provides an area correlator that compares an area under a feedback signal between timing signals with a reference area to generate feedback information and is particularly used in a discontinuous conduction mode (DCM) SMPS.

IPC: F24H9/20
Filed: 2006-11-10
Abstract: A flow control device 1 has a pair of flow regulators 7,9 controlling flow of water from an inlet chamber 3 to an outlet chamber 5. The regulators 7, 9 are mounted on a common spindle 11 for simultaneous adjustment to vary the flow rate.
