Title: The bandwidth of an adaptive filter is controlled by a proportional and integral (PI) controller
Inventor: HALIMIC MIRSAD
IPC: H03H21/00
Filed: 2002-05-31
Abstract: An adaptive filter, such as a low pass filter, has a time constant,   t  , controlled by the equation   t  = 1/  a  +  bW  ), where   a  is a constant,   W  is the difference between two successive values of a signal passing through the filter and   b  is the sum of a proportional controller gain Kp (a constant) and an integral term Ki/(1-z<-1>) , where the constant Ki is the integral controller gain. Thus a PI controller is provided for modifying the bandwidth of an adaptive filter. The controller may be a proportional, derivative and integral controller (PID), in which case   b  contains the additional term (1-z<-1>) Kd, where the constant Kd is the derivative controller gain. In a preferred embodiment the adaptive filter is connected in series with an adaptive channel equaliser. At the beginning of the adaptive equalization process the filter adopts a large bandwidth to maximise the adaption speed, but then automatically reduces its bandwidth when the equaliser becomes close to a static value, in order to decrease the effect of noise. The additional integral term reduces the disturbance rejection bandwidth and resonant frequency.

Title: Apparatus and method of signal modulation
Inventor: FRAZER EWAN LINDSAY
IPC: H04L25/03
Filed: 2003-02-13
Abstract: Signal modulation comprising: when a first predetermined condition is met for a first signal waveform; generating one or more temporary signal state-modifications to be applied to one or more data symbols within the first waveform, to generate a second waveform (which is therefore a modification of the first waveform) such that the amplitude of at least a part of the second waveform differs from the amplitude of the corresponding part in the first waveform. The temporary modifications are introduced to counteract overshooting from inter-symbol interference (ISI) caused by constructive or destructive interference between pulses of the first waveform. The first predetermined condition is met when the amplitude of the first waveform exceeds or lies below an associated maximum or minimum amplitude threshold value. The signal may be modulated according to a Quadrature Amplitude Modulation (QAM) scheme.

Title: Controlling bandwidth by introducing variable delay in transmission path
Inventor: CHRISTMAS JAMIESON LEIGH
IPC: H04L12/54
Filed: 2003-02-22
Abstract: A data transfer system includes a server 1 and a terminal 1. The transmission path between the server and the terminal has a nominal maximum bandwidth, the whole of which may be allocated when necessary (eg for streaming video, video conferencing and downloading large files). When the full bandwidth is not required, the terminal and server communicate with each other in such a way as to introduce a variable delay toward the terminal end of the transmission path. The delay may be introduced by making the terminal receive/transmit its data via a FIFO memory 5 whose clocking signal 7 may be delayed, thereby reducing the effective bandwidth usage of the terminal. The clock 7 may be adjusted under microprocessor control 8, in response to a bandwidth allocation request sent from the terminal to the server (fig.3). The terminal may be charged according to its bandwidth usage and thus only has to pay for provision of a high bandwidth connection when such a connection is required.

Title: Real time display of baseline filtered ECG
Inventor: BRODNICK DONALD EUGENE
IPC: A61B5/308
Filed: 2003-07-31
Abstract: Electrocardiographic (ECG) data is displayed on a display having two portions through which the data scrolls (right to left). The first portion 404 displays the most recently received data and the second portion 402 displays the remainder of the data. The data in the first portion has a continuously varying amplitude level adjustment applied to it for partial baseline correction, whilst the data in the second portion has a corrected baseline amplitude with no further amplitude level adjustment made to it. Hence the most recent data is repeatedly corrected as the waveform moves across the display (using a baseline estimate B computed from raw data each time a new data point is measured) whereas in the second portion no further adjustments are made to the data and the data retains the final value calculated in first portion as it scrolls across the remainder of the display. The method may be applied to other forms of data such as blood pressure data and seismic/geological data. A method of filtering and displaying sequential waveform data involving baseline correction and the creation of temporary data display samples is also disclosed.

IPC: G01D5/241
Filed: 2004-07-30
Abstract: The rotational speed and azimuthal vibration of blades 14 of a rotor 4 (e.g. of a gas turbine engine) are determined by measuring the capacitance between a rotating blade 4 and a point 22 off an axis 16 about which the blades rotate. Capacitive sensors 8 (92, figure 4) are placed off-axis (e.g. in the rotor casing 6).

To determine blade vibration, at least three capacitance measurements are taken at three different times using three sensors separated in the azimuthal direction (figure 4). The phase difference between the measurements is compared to the expected phase difference to calculate the vibration.
