Title: Retrieving data representing a postal address from a database of postal addresses using a trie structure
Inventor: BELLAMY DAVID JOHN
IPC: G06F17/30
Filed: 2000-10-12
Abstract: Data representing a postal address (30) is retrieved from a coded address database (6) representing, in the form of a tree of coded postal address elements (27, 28, 29), a multiplicity of postal addresses. A dictionary (4) formed as a trie data structure is provided, the path from the root node (10) to the leaf nodes (11) representing respective postal address elements. A processor (2) receives input data (8) comprising one or more input terms (8a, 8b) for finding a postal address (30) represented in the address database (6). The processor (2) searches the dictionary (4) for entries (31) exactly corresponding to the search terms and for entries (32a, 32b, 32c) allowing for the possibility of the input data containing one or more errors. The processor then finds, by reference to a location index (5), the matched coded postal address elements (27a, 27b, 28a, 28b, 28c) corresponding to the entries (31, 32a, 32b, 32c) in the dictionary (4) determined by the processor (2) as corresponding to the input terms (8a, 8b). The processor (2) then determines which of the matched postal address elements (27a, 27b, 28a, 28b, 28c) belong to the same address (30) and then with reference to a separate decoding index (7) decodes the address elements to output a full and correctly formatted postal address (9).

Title: Phased synchronisation for Time Division Duplex
Inventor: HULBERT ANTHONY PETER
IPC: H04B7/26
Filed: 2002-10-04
Abstract: A method of synchronising a plurality of base stations, for operation in time division duplex (TDD) mode in a mobile telecommunications network, utilises the transmission of coded synchronisation signals between base stations. An initial phase of over-the-air (OTA) synchronisation between base stations is employed to timing errors which remain after coarse synchronisation over the network as a whole. The method splits the initial phase into two sub-phases, in the first of which residual synchronisation errors are significantly reduced, or even removed. Operations effected during the second sub-phase thus benefit from the significant reduction in, or removal of, the timing errors and can therefore be implemented with less signal energy and exhibit reduced detection levels with regard to false synchronising signals. The coded signals may be respective groups of synchronisation burst signals transmitted repeatedly with differential phase modulation, and different codes may be incorporated into each synchronisation burst signal. Initially transmissions may be to all base stations, and later only to stations that have failed to receive synchronisation transmissions. The interval between transmissions may be chosen so as to de-correlate the transmissions.

Title: Extended cycle reciprocating gas compressor
Inventor: MA THOMAS TSOI HEI
IPC: F04B39/06
Filed: 2003-02-14
Abstract: A reciprocating gas compressor is described operating according to an extended cycle of 4, 6 or more strokes, wherein the first two strokes are sequential induction and compression strokes using a low pressure gas as working fluid and compressing it to a high pressure gas, and the remaining strokes are pairs of sequential filling and emptying strokes using more of the low pressure gas as heat transfer fluid for transferring heat from inside the gas compressor to outside the gas compressor. The gas compressor also contains a heat regenerator for absorbing heat from the compressed gas and releasing heat to the heat transfer fluid. The invention achieves a compression stroke which is near-isothermal and has significant advantages over the conventional gas compressor by virtue of fewer components, smaller size, lighter weight, lower operating cost and higher efficiency.
