Patent BR-9915776-A (BR)
Inventor: KHAYRALLAH ALI S
IPC: H04L27/00
Filed: 1999-09-14
Abstract: Methods and systems are provided for channel tracking utilizing multi-pass demodulation in which, during the second pass, decoded symbols are treated as known symbols which are used to calculate the error term used in updating the propagation characterization during the second pass. This allows a higher bandwidth to be used for updating the propagation characterization while known symbols are being processed. In particular, the propagation characterization may be provided by a channel tracker or a multi-antenna receiver, such as an interference rejection/combining (IRC) system, with an impairment correlation matrix estimator or a combination of both. Accordingly, the spatial diversity characteristics of the received signal (from IRC) and the temporal (or timing) characteristics (from the channel tracker) may both be tracked at different bandwidths for decoded and undecoded symbols to allow improved performance under fast changing channel conditions while maintaining desired performance characteristics while processing undecoded symbols.

Title: Demultiplexer timing control system
Inventor: MANSBRIDGE JOHN
IPC: H04B10/00
Filed: 2000-04-28
Abstract: There is provided an system for controlling the demultiplexing process in an optical backplane device (100). The system has application to optical switching in high-speed digital communication routers and switches. In demultiplexing, a selected compressed data packet (120) is extracted from a multiplexed stream of compressed packets by a modulator (102) and decompressed (104). The modulator (102) is controlled by a control signal (112). An error in the timing of the modulator control signal (112) corresponds to a characteristic distortion in the decompressed signal (116). By monitoring the effect of timing errors on decompressed signals (116), steps can be taken to correct the timing errors by controlling delays in either the optical or the electronic parts of the switching device. The timing of modulator control pulses (112) is thus continuously adjusted to minimise timing errors. Instead of monitoring just decompressed signals (116), calibration pulse trains of known value and suitable form can be inserted.

Title: Anti-stall hollow tip treatment bars for damage limitation
Inventor: HAND DEREK GEORGE
IPC: F04D29/54
Filed: 2000-05-19
Abstract: A gas turbine engine fan or compressor casing includes a cavity 10 separated from the main flow 12 through the engine by an annular array of tip treatment bars (16, fig 2) which delay the onset of stalling. The tip treatment bars 16 are hollow having internal passages 22 which enables the bars to deform or break upon impact by a shed blade 4 or blade fragment so that the blade or blade fragment may be contained within the cavity 10, or embedded in the casing 2, so causing the minimum of damage. The bars 16 may be a metallic or composite material, and are mounted on annular end supports 18,19 through which passages 22 may extend. Bar wall thickness may be between 0.5-1.5 mm. The interiors of the tip treatment bars may be filled with a damping material, to minimise high cycle fatigue failure.

Title: Receiver with self-diagnostic mode comprising various synchronisation detecting means and means to display diagnosis results to a user
Inventor: NINOMIYA SHUICHI
IPC: H04B17/29
Filed: 2000-05-26
Abstract: In a normal operation mode, a receiver Rx performs a predetermined processing on a digital broadcasting signal from an artificial satellite to generate sound. In a self-diagnostic mode, a controller 19 of the receiver Rx first sets a receiving frequency band of a tuner 2, and then carries out a diagnostic check whether a PLL circuit 20 is defective or not based on the detection result from a PLL sync detector 3; the receiver input can be either a digital broadcast signal or a simulated broadcast signal. If the PLL circuit 20 is normal, it is checked whether a QPSK demodulator 21 is defective or not based on the detection result from a QPSK sync detector 22. If the QPSK demodulator 21 is normal, it is checked whether frame synchronization is failed or not in a CH decoder 24 based on the detection result from a frame sync detector 25. If frame synchronization is normal, it is checked whether channel synchronization is failed or not in the CH decoder 24 based on the detection result from a CH sync detector 26. If the controller 19 determines that the PLL circuit 20, the QPSK demodulator 21, or the CH decoder 24 is defective, a display 18 notifies an inspector of the diagnostic result. The receiver Rx thus can reliably and quickly carry out a diagnostic check as to whether each of components comprising thereof is defective or not.

Abstract: A pixel array (20, 30, 41, 50) for a dot matrix character display having improved resolution is formed from a regular lattice of main pixels (21) bounding intermediate auxiliary pixels (22) of generally smaller dimension than the main pixels, such that any character can be formed by illuminating edgewise adjacent pixels only. The pixel array may include a regular lattice of main pixel boundaries having a first polygonal shape defining at mutually abutting edges thereof a respective auxiliary pixel boundary having a second polygonal shape of generally smaller dimension than the first polygonal shape. The main and auxiliary pixels are contained within each of the main and auxiliary pixel boundaries, respectively. Preferably, the pixel array has a pixel resolution compatible with existing display drivers so as to allow easy modification of existing display drivers by substitution of the character map therein. Tri-colour pixels may be employed to allow colour rendition of bit-mapped characters.

Patent GB-2370960-A (GB)
Title: Partially shielded photodiode array
Inventor: GRAVES MARK
IPC: H01L31/0216
Filed: 2001-01-05
Abstract: An array of photodiodes is provided, at least one of which is shielded from incident signals such as by a lead cover, for x-ray sensing. In a linear array, this photodiode is preferably at the end of the array as it can then be ignored for the purpose of creating an image. In this way, the shielded photodiode always gives a dark output and can be used to provide a running calibration for the remaining photodiodes. Thus, the output of the one photodiode is subtracted from the output of other photodiodes in the array. If the temperature rises (for example) then the signal of all photodiodes will increase but the signal after subtraction will remain the same.

In this manner a system designer may set operating characteristics for various system components based on the topology of the specific system rather than designing for a worst-case scenario.

Title: Method of positioning a vessel and vessel provided with turet braking and locking means
Inventor: ISNARD JEAN-LOUP
IPC: B63B21/50
Filed: 2000-05-29
Abstract: The invention relates to a method of positioning a vessel (1) comprising a hull (6), a cylindrical turret well in said hull and a turret (3), which is rotatably supported in said turret well. The turret may comprise a flange (15) on which two circular raceways (16, 17) are provided. Flange is supported on bogey wheels (12, 13). Via a hydraulic jack (20) carrying a friction pad (22), the rotational movements of the hull around the turret may be restricted until the hull is substantially stationary with respect to the turret, whereafter the position of the turret relative to the hull of the vessel may be locked, for instance by lifting the flange free from the bogey wheels. In this way the heading behaviour, especially during heavy seas, can be improved without the need for auxilliary positioning devices such as thrusters (8).
