Title: Bubble display device.
Inventor: BUTCHER TREVOR
IPC: F21S10/00
Filed: 2002-02-14
Abstract: A display device in which bubbles of a first fluid are caused to rise through a second denser fluid, in which the first and second fluids are different colours, comprises at least one chamber (14, 15, 16) for containing the second fluid with a reservoir (20, 21, 22) at the top of the chamber for holding a volume of the first fluid. There is preferably more than one chamber and they are formed into a number of layers, each having a second fluid of a different colour so that colourful patterns are created as bubbles in different layers overlap. The first fluid is preferably pumped in a closed loop (Fig. 5) by a positive displacement pump. There may be a different pump for each chamber. The reservoir at the top of each chamber is preferably formed by a pair of divergent upper wall portions. The sides of each chamber may be formed with inward projections (50, Fig. 2) to enhance the movement of the bubbles. A lamp (40) may be provided for illumination.

Title: Raman amplifier and optical transmission system
Inventor: TANAKA TOSHIKI
IPC: H04B10/079
Filed: 2002-03-21
Abstract: A Raman amplifier (10) comprises an excitation light source (11) that generates excitation light (P 1 -P M ) having a wavelength band overlapping a wavelength band of the transmission signals (S 1 -S N ), a multiplexing unit (12) that supplies the excitation light to an optical transmission path (1), and an optical filter (13), e.g. a Bragg grating, that suppresses components of light propagated through the optical transmission path (1) which are of the same wavelengths as those of the excitation light, e.g. Rayleigh scattered light (R M+1 -R M ). In such a Raman amplifier, and an optical transmission system incorporating such a Raman amplifier, characteristic deterioration caused by excitation light co-existing within the wavelength band of the transmission signals can be reduced. Application to optical time domain reflectrometry is also disclosed.

Title: An OFDM receiver obtains, for each symbol, a composite channel state indication, representing the channel state in a plurality of carriers
Inventor: ROBINSON ADRIAN PAUL
IPC: H04N7/24
Filed: 2002-05-01
Abstract: A DVB-T receiver includes a channel equaliser (110), a metric assignment and demapping circuit (112), an inner interleaver (122), a Viterbi decoder (124), an outer interleaver (126) and an outer or Reed-Solomon decoder (128) . The metric assignment and demapping circuit (112) includes a soft-decision quantising arrangement (224, 226) which provides confidence values for the Viterbi decoder. The quantising arrangement receives a control input from channel state indication (CSI) measurement circuitry (240, 260, 280). A further channel state indication is obtained on a symbol-by-symbol basis (240,302). This is compared (318) with an average obtained (316) over a few symbols, to detect impulsive interference, and applied (320, 294) as part of the control for the soft-decision quantiser. Erasures information is provided from the Viterbi decoder (124) to an erasures input of the Reed-Solomon decoder (128). A signal derived from the further channel state indication is also applied to the erasures input of the Reed-Solomon decoder (128). Deeper symbol deinterleaving is used in the outer deinterleaver (126), over a block of size of e.g. four symbols.

Title: Self-cleaning fuel oil strainer
Inventor: BENENSON JR JAMES
IPC: B01D29/15
Filed: 2000-10-11
Abstract: A self-cleaning fuel oil strainer, coupled to a continuous fuel flow, that includes a pair of canisters, each having a cylindrical wedge wire fuel oil filter screen. An elongated brush running the length of the screen is disposed between two confining walls also running the length of the screen to form a chamber. A elongated partition, including two sets of apertures, is used, along with the elongated brush, to divide the chamber into two particulate dislodge chambers and a drain subchamber. A drain is in fluid communication with the drain subchamber. During cleaning, the drain is opened and the screen is rotated against the brush for liberating the particulate contaminants and a limited amount of fuel oil into the two dislodge subchambers. The particulate contaminants and the limited amount of fuel oil then pass through the apertures at a high velocity and into the drain subchamber which exits through the drain. Alternatively, a reverse flow of clean fuel oil can be used in combination with the elongated brush, for dislodging the particulate contaminants from the fuel oil filter screen. Finally, another variation of using a reverse flow of clean fuel oil for cleaning purposes is discussed whereby a stationary fuel oil strainer is disposed in a system that isolates the fuel oil strainer from the normal fuel oil flow during cleaning.

Title: Method of transforming competent cells
Inventor: CHEN TZU-CHIH
IPC: C12N15/87
Filed: 2002-11-07
Abstract: The invention provides a fast method of transforming competent cells, comprising thawing the cells, mixing them with plasmid DNA, heating the cells for up to 180 seconds to perform heat shock treatment, plating the mixture on a selective medium at 0-30 degrees C, using a plating tool at -90 to +30 degrees C, and culturing the mixture to obtain transformed cells. No recovery step is performed prior to plating the cells. Preferably, the selective medium and the plating tool are kept at a low temperature for the plating process. The method preferably uses a single container from thawing to plating, and so may easily be automated. The invention also provides automated apparatus for use in transforming cells according to this method.

Title: Residual echo estimation for echo cancellation
Inventor: DEISHER MICHAEL E
IPC: H04M9/08
Filed: 2001-09-14
Abstract: Real and imaginary components of the discrete Fourier transform (DTF) of the residual echo in an acoustic echo cancellation system are separately estimated using mapping functions derived without an assumption of statistical independence between separate components of a near-end microphone input signal. The residual echo estimator calculates the real and imaginary components using an approximation of the microphone input signal without the echo. A different approximation is used depending on whether the near-end talker and/or the far-end talker are talking.

Title: Optical AC current sensor
Inventor: SHAN XUEKANG
IPC: G01R15/24
Filed: 2003-04-05
Abstract: A sensor for measuring the AC current flowing in a conductor 1 comprises a coil 2, electro-optic modulator 4, light source 5, photo-detector 6, DC bias circuit 7 and signal processor 8. The coil 2 converts the current to an AC voltage, and the optical signal from the light source 5 is then modulated according to the depth of the driving voltage by the electro-optic modulator 4. The modulated signal is sensed by the photo-detector 6 and manipulated by the signal processor 8 to provide an estimate of the AC current as a function of the ratio of the amplitude of the voltage signal to the amplitude of the time-averaged signal. A DC bias circuit 7 is required to correctly sense positive and negative voltages. The current sensor is theoretically independent of optical power and polarisation effects and depends only on the modulation depth.

Title: Correction of colour calibration values obtained from a colour calibration pattern
Inventor: GUDIATIS ALGIRD M
IPC: H04N1/60
Filed: 2002-09-24
Abstract: Correcting color values for color calibration is disclosed. A sensor measures a color calibration pattern output by a device, to obtain color values for the patch (104). Corrective action(s) are then performed on the color values (106). A first such action corrects for slow drift measurement corruption of a patch color of the patch by both scaling and offsetting the colour values (900). A second action may correct for non-parallel motion of the sensor while measuring the patch (500). A third corrective action may correct for ambient light detected by the sensor while measuring the patch, without necessarily filtering the sensor (700).
