Patent GB-2352376-A (GB)
Title: Telemetry system in which data signals are modulated on power signals
Inventor: SHANKS DAVID SIRDA
IPC: E21B47/12
Filed: 2000-04-27
Abstract: A telemetry system is capable of transmitting both power and data signals between a master unit 10 and at least one slave unit 50 (a,b) over a transmission system 12 which is part of a borehole, an oil well or a pipeline which may be a subsea installation. The transmission system comprises a tubing string or pipeline incorporating electrically isolating collars 200 a,b. A well casing or another pipeline may provide an earth/return path, the slave unit 50 being coupled between the tubing string and the well casing or between the two pipelines. The master unit 10 may use pulse width modulation of a power signal from driver 24 to send data to the slave unit 50. Power signals received by the slave unit are fed to regulators 56,58 to provide a local power supply for the slave unit. Data signals from the slave unit may be encoded by frequency shift keying at generator 64, synchronised with the pulses of the power signal, for transmission to the master unit. Data signals sent from the master unit may be detected by a timer circuit 70 and used to control valves, actuators or motors, while the data signals form the slave unit may represent the outputs of sensors. The data signals may be encrypted, e.g. using a Hamming code.

Title: Detecting changes in parameters or condition of cells in a suapension
Inventor: TODD ROBERT WILLIAM
IPC: G01N27/02
Filed: 2000-09-13
Abstract: Changes in the parameters or conditions of cells in a suspension are determined by making impedance measurements of the suspension at a number of different frequencies. These measurements are used to determine any change in the frequency-dependent impedance characteristic, indicative of changes other than cell concentration or conductivity of the medium in which the cells are suspended. Preferably the impedance characteristic which is measured is frequency-dependant capacitance or frequency-dependant conductivity and changes are detected from a change in the fundamental shape of the characteristic or from a displacement of the characteristic curve along the frequency axis. The method may be carried out in apparatus which comprises an impedance analyser with microprocessor controlled frequency variation, storage of measured values, and detection of changes.

Title: Optical infrared gas analyser
Inventor: DREYER PETER
IPC: G01N21/3504
Filed: 2001-07-02
Abstract: The invention relates to an optical infrared gas analyser having at least one optical infrared radiation source (6, 7), two multispectrum detectors (1, 2) and a cuvette (12) containing the gas mixture to be measured and to the simultaneous measurement and identification of a multiplicity of gases in a gas mixture. The radiation emitted by an optical infrared radiation source (6) comprises a first wavelength range [  g  <SB>1</SB>,   g  <SB>1</SB>'] and the radiation emitted by an optical infrared radiation source (7) comprises a second wavelength range [  g  <SB>2</SB>,   g  <SB>2</SB>'] chosen as different therefrom. The path lengths each proceed through the interior of the cuvette (12) and impinge on the multispectrum detectors (1) and (2). The latter passes the received signals to an evaluation and control unit (13) that calculates the gas concentrations taking account of cross-sensitivities in the measurement by means of the multispectrum detectors (1) and (2).

Title: Filter
Inventor: SIEGEL ERWIN FREDERICK
IPC: G01R13/20
Filed: 2002-11-26
Abstract: A filter includes an analyzer 11, thresholding circuit 12, and synthesizer 13. The analyzer generates a low-frequency component signal YL and a high-frequency component signal YH from an input signal 15. The thresholding circuit generates a processed high-frequency signal YH' from the high-frequency component signal, the processed high-frequency signal having an amplitude of zero in those regions in which the high-frequency component signal has an amplitude that is less than a threshold value. The synthesizer generates a filtered signal from input signals that include the low-frequency component signal and the processed high-frequency signal. The filtered signal is identical to the input signal if the threshold value is zero. The analyzer is preferably constructed from a plurality of finite impulse response filters that operate on a small fraction of the input signal at a time. A plurality of analyzers may be provided in series to decompose the input signal into a larger number of sub-bands (figure 2).

Title: Apparatus for polarization-independent optical polarization scrambler and a method for use therein
Inventor: EVANKOW JR JOSEPH DAVID
IPC: G02F1/01
Filed: 2001-08-03
Abstract: A technique, specifically apparatus (5) and an accompanying method, for an optical scrambler and particularly one that provides scrambled states of polarization (SOPs in an optical fiber (4). Specifically, polarization independence is achieved by wrapping a single optical fiber (4) around each tube in a cascade of separate piezoelectric tubes (PZTs) (10; 10 a , 10 b , 10 c , 10 d , 10 e  10 f ), with random amounts of fixed birefringence (30; 30 a , 30 b , 30 c , 30 d , 30 e , 30 f ) separating each tube, where each tube is then separately excited on a time-varying basis. The tubes are arranged in two groups (10 1 , 10 2 ), of illustratively three tubes each. Each tube in the first group is separately excited by combined frequency/amplitude modulation (20a, 20 b,  20 c ) with illustratively different modulating frequencies and amplitudes. Each tube in the second group is excited at illustratively a constant frequency and voltage (20 d , 20 e . 20 f ). The excitation applied to each tube causes that tube to exhibit geometrical, physical displacement which, in turn, imparts a time-varying birefringence to light as it passes through that portion of the fiber wound around that particular tube. This time-varying birefringence produced by each tube perturbs an initial SOP of the light provided by that tube from its original pseudo-stationary position as depicted on a Poincar sphere.

Title: Multi-turn loop antenna mounted under wheel-arch in tyre pressure monitoring system
Inventor: NANTZ JOHN S
IPC: B60C23/04
Filed: 2003-02-25
Abstract: An initiator sends a low frequency (125 - 135 kHz) initiation signal to a tyre monitor mounted in a tyre which causes the tyre monitor to transmit a tyre pressure signal to a receiver/controller mounted in the vehicle. The initiation signal is transmitted to respective tyre monitors by respective multi-turn loop antennas 42 which are located in the wheel wells 46. The antenna is either moulded into the non-metallic material which comprises the wheel well, or is formed on non-metallic backing material which is adhered to the surface 50 of the wheel well. The antenna conforms to the surface of the wheel well, and may be planar or non planar (typically semi-cylindrical). An electromagnetic field generated by the initiator may be used to recharge a battery in the tyre monitor. The system provides automatic identification of the location (front, rear, left, right) of each tyre.
