Patent GB-2403167-A (GB)
Title: High flux filtration system
Inventor: JOHNSON MARK
IPC: B01D63/16
Filed: 2003-06-28
Abstract: A filtration system with reduced blocking by captured material and with improved flux and size discrimination is formed by exciting a flexible micro-structured membrane 27 into vibrational motion. Typically the vibration will be at ultrasonic frequencies and in one embodiment the excitation is in the form of a transverse standing or travelling wave. The transverse wave motion is effective in fluidising filter-cakes which form on the surface of the membrane. The membrane should be microstructured with pores formed lithographically, by ablation or by the track-etch process using an additional masking step, typically providing porosity only in certain areas of the membrane away from the supported edges. The high pore density gives a high initial flow-rate, while the vibration maintains the high flow essentially indefinitely. The vibration allows smaller particles to pass though the filter, along with a larger volume of the carrier fluid, while still retaining the larger particles. In this way the volume of fluid that can be screened is greatly increased, typically by 10-100 times, allowing more particles to be captured for analysis.

Title: Brain signal analysis to detect spikes and rhythmic patterns
Inventor: LOWE DAVID
IPC: A61B5/0476
Filed: 2003-07-19
Abstract: Brain signals are analysed to detect transient features of interest in the signals (e.g. spikes, anomalous activity) by representing multichannel EEG data as multidimensional EEG vectors, comparing the EEG vectors with pre-calibrated reference vectors, and identifying the reference vector that is the closest match to the EEG vector. The reference vectors are associated with a probability of representing a feature of interest. If the probability associated with the identified matching vector exceeds a threshold the ECG data is determined to have a region of interest. The analysed data can be used to assist in the diagnosis of epilepsy. Also disclosed is the analysis of EEG data to identify rhythmic patterns associated with an epileptic seizure, where a data sample window is used.

Title: Method and apparatus for controlling cell selection in a cellular communication system.
Inventor: MOLKDAR DAVOOD
IPC: H04L27/00
Filed: 2004-05-05
Abstract: A base station (101) may transmit using different modulation schemes. The transmit power of a pilot signal used for cell selection varies depending on the modulation schemes currently used, for example due to varying power amplifier back-up requirements. The base station (101) comprises a modulation scheme processor (113) determining a modulation scheme distribution for a plurality of communication channels of the cell. The modulation scheme distribution reflects the current modulation scheme utilisation for the pilot signal and is indicative of the power variation of the pilot signal. A cell selection processor (115) modifies a cell selection criterion in response to the modulation scheme distribution. In particular, the cell selection processor (115) determines a cell selection power offset to be applied to measurements of the signal levels of the pilot signal. The cell selection power offset preferably corresponds to the average power variation resulting from the current modulation scheme utilisation thereby allowing this to be compensated.

Title: Circular super-directive receive array with an odd number of antenna elements
Inventor: BARRICK DONALD E
IPC: H01Q21/06
Filed: 2004-07-08
Abstract: An antenna array comprises an odd number of antenna elements 1 - 7 in a circular array with a radius that is less than a detected wavelength. The number of antenna elements and the radius of the circular antenna array may be determined from a calculated value of the minimum antenna array efficiency and the maximum antenna array super-directive gain. The efficiency value may be established by finding the optimal operational point in the relationship between the internal noise of the antenna array and the noise level arising from sources external to the antenna array and the radius of the antenna array. One or more signal processors 20 may be used to control the signal amplitude and phase weights being applied to the antenna elements 1 - 7 to obtain the desired signal beam. A method of signal cancellation may be used to supplement the antenna's characteristics to obtain an effective overhead null. The antenna array may provide a cheap, compact antenna array with an efficient narrow beam with suitable gain and signal to noise ratio which may operate in medium, high and very high frequency (MF, HF, VHF) ranges.
