Title: System for determining the unique identity codes of a plurality of transponders
Inventor: REGAN BERNARD JOHN
IPC: G07C9/00
Filed: 1998-08-18
Abstract: A transponder identification system comprising a plurality of transponders 4 and an interrogation device 2 arranged to identify each of the transponders by transmitting successive interrogation signals according to a systematic search strategy (eg. tree search). The search strategy is truncated if the interrogation device receives fewer than a predetermined number of different responses from the transponders 4. In this case the particular combination of values received in one of the responses is transmitted, this time by the interrogation device, so that any unidentified transponder holding that combination of values in the corresponding fields of its identity code will respond by transmitting the remainder of its unique identity code. Once a transponder's identity code has been determined an acknowledgement signal containing the full identity code is transmitted to prevent that transponder from responding to further interrogation signals. However, the transponder will continue to respond to an "are you still there?" signal, comprising either the transponder's full identity code or another signal uniquely defining the transponder. The interrogation device detects any interference between transponders and in that case interrogates those transponders further.
Patent GB-2328660-A (GB)
Title: Articulated vehicle track link and connector
Inventor: HAGGER PAUL MARTIN
IPC: B62D55/21
Filed: 1998-08-28
Abstract: An articulated vehicle track unit comprises two links 1, two pins 3 each passing through one of the links and an end connector for connecting the pins of adjacent links. The end connector comprises a stepped diameter retaining bolt 6 and a clamping member 5 with two recesses 7 each for receiving the end of a pin and two aligned holes 8, 9 through which the bolt can pass between the recesses. Each pin has a land 4 in its side and when the bolt is screwed into hole 8 the periphery of the bolt sits in the lands and resists removal of the clamping member from the pins. The end connector is retained by both the bolt engaging the notches and by a clamping action due to tightening the bolt. The bolt may have a taper to encourage a tight fit.

Title: An ink-jet printing ink
Inventor: MOFFATT JOHN R
IPC: C09D11/30
Filed: 1998-09-23
Abstract: A smearfast, waterfast, and fast drying ink is provided, employing macro-molecular chromophores (MMCs) and both ionic surfactants and zwitterionic, or amphoteric, surfactants, in which the ionic surfactant is of the opposite polarity of the MMC. Macromolecular chromophores are pigments whose surface has been treated to provide either anionic or cationic functional groups thereon. The zwitterionic surfactant gives rise to waterfastness, while the ionic surfactant gives rise to both smearfastness and fast drying.

Title: Speech parameter compression; distributed speech recognition
Inventor: HAAVISTO PETRI
IPC: G10L19/18
Filed: 1998-10-13
Abstract: In a method for compressing feature extracted parameters of a speech waveform, at least a first set of selected ones of the feature extracted parameters are transform coded to provide a plurality of transform coefficients, and at least one of the transform coefficients is differential pulse code modulated (DPCM). Mel-frequency cepstral coefficients <I>c<SB>1</SB></I> to <I>c<SB>12</SB></I> are buffered (36, Fig.5a) and then transformed (38) using a discrete cosine transform (DCT) to form DCT coefficients DCT<I><SB>x,1...8</SB></I>. The first DCT coefficients are DPCM encoded (Fig.5b) with periodic pulse code modulation (PCM) updates to ensure synchronisation between a transmitter and a receiver.. PCM is applied to the other DCT coefficients, these coefficients being quantized using probability density function (pdf)-optimised quantizers. The zero order cepstral coefficient <I>c<SB>0</SB></I> and the logarithmic energy <I>logE</I> are DPCM coded with periodic updates similarly to the first DCT coefficients <I>DCT<SB>x,1</SB></I> . The memory requirement of the compression method is such that a front-end (FE) for feature extraction and a compressor can be incorporated in a mobile telephone handset, a decompressor and a back-end (BE) for speech recognition being located at a central place in a cellular network.

Patent GB-2345154-A (GB)
Title: Positioning, eg for aligning waveguides and optical fibres
Inventor: DAVIES PHILIP ANDREW
IPC: G02B6/42
Filed: 1998-12-23
Abstract: A plurality of uniaxial positioning elements of positioning stages (4, 6) are driven to perform an automated search to find a signal in a multi-dimensional search space having a dimensionality equal to the number of alignment axes (X1, Y1, X2, Y2). The automated signal location is achieved by scanning over a search pattern defined by a succession of n-1 dimensional closed hyper-surfaces in an n-dimensional search-space, where n is the number of positioning axes involved in the alignment process. In an embodiment hyper-cubes are used as the hyper-surfaces and the search path follows a hyper-spiral track over hyper-surfaces of incrementally increasing size. One application is to align input and output optical fibres (7 and 8) with a solid-state waveguide structure (3) mounted on a plinth (5) under the control of a positioner controller (9) which outputs motion control signals for the positioning elements over control paths (18) so as to scan over paths on a succession of nested hyper-surfaces until a signal is received through a signal line (19).

Abstract: 983,998. Vibration detectors. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 13, 1962 [Aug. 15, 1961], No. 30993/62. Heading H4J. A seismometer comprises a coil body consisting of a hollow cylindrical body, on which are mounted one or more coils, suspended in a magnetic field in a stationary casing by means of one or more flat disc-shaped leaf springs which fit in annular grooves on the inside of the body near an end, the spring having a resilient lug which fits into a radial slot in the coil body. As shown, Fig. 3, a seisometer comprises a permanent magnet 18 with polepieces 19, 20 round which is a coil body 1, with a pair of coils connected in series, supported by two springs 7<SP>1</SP>, 7<SP>11</SP> of phosphor bronze or beryllium copper. The assembly is mounted in an iron casing 15 by end pieces 16, 17 of aluminium insulated by anodizing. Electrical connections are made to the coils by springs 7<SP>1</SP>, 7<SP>11</SP>, wire 21 being connected directly to spring 7<SP>1</SP>, while wire 22 is connected to spring 7<SP>11</SP> through magnet 18 and polepieces 19, 20. The springs 7 are mounted in slots in the inside of the body 1, as shown in Fig. 2, and have a lug 12 which fits into a slot 13 in the end of the body. The springs 7 have slots 8 to increase their resilience and holes 9, 10, 11 for mounting and electrical connections. The springs 7 are fitted by placing lug 12 at one side of slot 13, inserting the edge of the spring into the groove and rotating the lug to " screw " the spring into the groove. After one revolution the lug springs into its slot and the spring is fully inserted. The springs are removed by lifting lug 12 and " unscrewing " the spring. The spring has notches cut on both sides of lug 12 to increase its resilience. The poling of the device can be determined by applying a D.C. voltage. In one poling spring 71 touches polepiece 19 shorting out the coils and causing the device to act as an interrupter. In the other poling no shorting can take place.
