Title: Improvements relating to chrominance selective filtering for use in colour video signal decoding
Inventor: EASTERBROOK JAMES EDWARD
IPC: H04N9/78
Filed: 2001-07-20
Abstract: A chrominance selective filter for filtering a sampled composite colour video signal to extract the composite chrominance component therefrom, includes a Fourier transform circuit (50) to convert a received sampled composite colour video signal from the time domain to the frequency domain and thereby provide a plurality of multi-dimensional frequency components. A transform domain filter (40) differentially changes the amplitudes of some of the frequency components relative to the others, without changing the phase information, and an inverse Fourier transform circuit (52) converts back from the frequency domain to the time domain. The transform domain filter changes the component amplitudes so as to select frequency components at least predominantly representing the composite chrominance component. This is done for a given component by locating the component which is in multi-dimensional frequency space at a mirror image position about a colour subcarrier, and setting the amplitude of the larger of the two components to that of the smaller component. The filter may operate in two dimensions (horizontal-vertical) or in three dimensions (horizontal-vertical-temporal). The chrominance selective filter may be used in a PAL decoder, having a subtracter (14) which receives an input sampled composite colour video signal at its non-inverting input and the output of the filter at its inverting input, the filter also receiving the sampled composite colour video signal as an input. The filter output is the chrominance signal and the subtracter output is the luminance signal.

IPC: E21B47/12
Filed: 2001-07-25
Abstract: A system for communicating between a bottom hole assembly 114 next to a drill bit 110 and a drilling rig 130 whilst drilling, has a cable 116,134 running both inside (cable 116) and outside (cable 134) the drillpipe 120, 136. The outer cable 134 may be situated between the drillpipe 136 and a riser 118 only. The junction between the inner and outer cables 116,134 is provided by a wet connect crossover sub 126. The outer cable 134 is attached to the outer surface of the drillpipe 136 by clamps (158 fig 6). A cable reel (142, fig 6) is used to spool the cable into or out of the well. A rotary table (162, fig 7) which has a protective plate (170, fig 7) is fixed on the sea floor. The plate (170, fig 7) protects the cable 134 from damage if the drillpipe 136 moves.

Title: Method of towing and installing a pipe
Inventor: COCKSEDGE BRIAN
IPC: F16L1/16
Filed: 2002-01-25
Abstract: Rather than directly towing a pipe 30 from a tug 11, a cable 23 is suspended between two surface vessels 10, 11, and it is from this cable 23 that the pipe 30 itself is suspended at a plurality of points. By means of this arrangement, stress and fatigue is absorbed by the cable 23 rather than the pipe 30, such that the pipe 30 arrives at its installation point with a correspondingly smaller loss in fatigue life. In a further embodiment, the cable can extend through the pipe, and is preferably supported along its length by spacers to keep the cable in the centre of the pipe (figures 7 and 8).

Title: Synchronisation in OFDM
Inventor: MEHTA MEHUL
IPC: H04L7/04
Filed: 2002-12-03
Abstract: A method of synchronising an Orthogonal Frequency Division Multiplexed (OFDM) IEEE 802.11a data packet at a receiver is disclosed. The 802.11a data packet has a series of short training sequence (STS) symbols as a preamble. Cross-correlation at the receiver of the STS in the 802.11a packet PLCP preamble with the modified reference STS, that is circular shifted by eight samples, results in a main correlation peak but with reduced pre- and post-lobes. To locate the cross-correlation peak, a running second derivative of the cross-correlation function is performed. Peak selection employs a running comparison of the position and magnitude of all peaks in the intermediate neighbourhood of the local peaks. Following selection of a peak from within the cross-correlation function of the first STS in the PLCP preamble, both the position and magnitude of the first STS is compared to those of the second STS. Based on the two independent calculations, the start of the OFDM frame is estimated.

Abstract: A combination set (Fig. 1, A,B), that may be provided in different sizes, includes complete arched denture teeth units (1), (2) preformed without denture base, for setting up denture teeth instantly and adjustably in a full balanced articulation during custom denture work. The set(s) is composed of a complete upper (1) and separate complementary complete lower (2) arched denture teeth unit, each including anterior and posterior denture teeth inter-connected either in a complete (A) or under-extended complete (B) tooth arch at least in an oval form. Each of the units includes a total unitary inter-occlusal bite plane preformed in a corresponding centric occlusion and full balanced articulation. So as to not have to set up denture teeth one by one in the centric and full balanced articulation, the unitary inter-occlusal bite plane is pre-set according to interconnected anterior and posterior denture teeth. While the posterior denture teeth are formed cuspless spheroellipsoidal, conforming a 4 inch (11 cm.) radius, thereby pre-set either in a planar or anterio-posterior or curved sphero-ellipsoidal arrangement including a free centric inter-occlusal contact (Fig. 2) either full (C, 5) or partly (D,6) and a free eccentric bi-lateral balanced articular contact. The set(s) is formed from a non-bendable durable tooth aesthetic material. The invention includes further a method A for preforming the set(s) from the material by providing a durable economised mould structure and a method B for setting up the set(s) in an instant and adjustable full balanced articulation with the provision of an auxiliary set of tools.

Title: Method for testing a hydraulic vehicle braking system for undissolved gas in the brake fluid
Inventor: TRAUTMANN TORALF
IPC: F15B21/044
Filed: 2003-11-12
Abstract: The invention relates to a method for testing a hydraulic, in particular an electrohydraulic, vehicle braking system (10) with a main brake cylinder (12) for undissolved gas in the brake fluid. The invention proposes to measure the pressure in the main brake cylinder (12) as a function of travel of a piston of the main brake cylinder (12) (piston travel) during operation of the main brake cylinder (12) and to calculate a smoothed, steady pressure characteristic within individual piston travel ranges (1, 2, 3). A comparison of the calculated pressure characteristic with a target characteristic (eg., the case of brake fluid devoid of gas bubbles) permits the conclusion to be drawn regarding the presence of gas bubbles in the brake fluid.
