Patent GB-2364792-A (GB)
Title: Flow control valve
Inventor: VARNEY BRIAN ANTHONY
IPC: G10K11/178
Filed: 2000-07-12
Abstract: A flow control valve for a combustion unit includes a first member (48) located in a fuel or air flow path so as to define an annular flow therearound. A second member (68) is mounted so as to be rotatable substantially around the first member and a flow path is defined between the first and second members. Rotation of the second member (68) about the first member (48) causes a cyclical variation of the effective cross sectional area of the flow path, with a single cycle of relative rotation of the first and second members causing the effective cross sectional area of the flow path to pass through a plurality of maxima and minima. Fuel leaving the valve thus has a steady component defined by the minimum fuel flow and an unsteady component defined by the variable fuel flow. The unsteady component may be brought into antiphase with a detected noise or vibration level, in order to minimise such noise or vibration.

Title: Impedance modulation signalling
Inventor: WOOD JOHN
IPC: H04L25/02
Filed: 1999-01-11
Abstract: Signalling between transmitting means and receiving means wherein signals from the transmitting means are subjected by the receiving means to deliberate reflections and resulting signals are transmitted back as meaningful at the transmitting means, different deliberate reflections having effects on said resulting signals that have different meanings at said transmitting means. Two-way signalling involves first signalling in one direction by sending signals with certainty of deliberate reflection thus resulting signals for return related to the signals sent according to the nature of the deliberate reflection and second signalling in the other direction by varying the nature of the deliberate reflection.

Title: Signal enhancement for fluorescence microscopy
Inventor: WHITE JOHN G
IPC: G02B21/00
Filed: 1999-01-25
Abstract: Multi-photon excitation fluorescence microscopy is carried out by focusing an excitation beam (12) by an objective lens (20) onto a specimen (22) and collecting the multi-photon fluorescence light emitted from the specimen (22) to the objective lens (20) and directing the fluorescent light on an optical path to a detector (35). Fluorescent light emissions from the specimen (22) collected by a condenser lens (25) on the opposite side of the specimen from the objective lens (20) are directed to a dichoic mirror (30), which reflects the light photons back into the condenser lens (25) and thence into and through the objective lens (20) where they are directed on a optical path to the detector (35). Significantly increased fluorescent photon collection efficiency is obtained as well as improved image intensity of the detected fluorescent light.

The means 34 for applying identifying signals may be a variable optical attenuator, and the demultiplexer may be an optical channel modulator or array waveguide. The photodetector array may consist of photodiodes. In another embodiment, an input signal may be passed through a splitter into two optically conducting branches. Each branch may be selectively attenuated, the demultiplexer acting on the signal from the first branch when the second is attenuated and vice vera (see figure 1). The apparatus is used to determine parameters of each channel of the optical input, such as wavelength, relative power or amplitude, or optical signal-to-noise ratio.

Title: Marking material using a two part watermark
Inventor: PELLY JASON CHARLES
IPC: G10L25/51
Filed: 2001-12-13
Abstract: A watermarking system comprises an encoding data processor operable to generate at least one marked version of an original item of material by introducing one of a predetermined set of code words into a copy of the original material item. Each of the plurality of code words of the set is uniquely associated with a data word having first and second fields. Each of a set of values of the first field is represented as a first part of the code word having a first plurality of coefficients, and the second field is represented as a second part of the code word having a second plurality of coefficients. By providing watermark code words having first and second parts, a data word with first and second fields can be uniquely identified. The first and second fields can be assigned to different associated parameters such as for example address parameters. The first field could therefore identify the country of distribution of the material, whereas the second field could identify a particular distribution outlet within the country. A watermarking system can be formed, which finds particular application in identifying a point of distribution of pirate copies of video material using, for example, a camcorder in a cinema.
