Abstract: A texture description method in frequency domains and a texture-based retrieval method using the same, in which image signals are converted into those in a frequency domain of Polar coordinate system (Figure 4). The texture description method in the frequency domain comprises: a first step of generating a frequency layout (515) by partitioning the frequency domain into a set of feature channels; a second step of extracting the texture feature values of the image from the respective feature channels (512-514); and a third step of constituting a texture descriptor of the image in a vector form (516) using the texture feature values extracted from the respective feature channels of the frequency layout. According to the present invention, in a texture-based retrieval described in the frequency domain, a retrieval method capable of satisfying respective or all the retrieval conditions such as scale-, rotation- and intensity-invariant retrieval of relevant texture images is provided. Also, a retrieval method of computing the rough scheme of texture to provide a browsing functionality in retrieving is provided.

Title: Magnetic analyser for paramagnetic gases
Inventor: CHIBA RYUUJI
IPC: G01N27/74
Filed: 2001-05-22
Abstract: An analyser determines the concentration of a paramagnetic gas, e.g. oxygen, in a mixture of gases. The analyser comprises a magnetic field, generated by two opposite poles 1a and 1b of a magnet, a heater 7 and a heat sensor 2c. The heat sensor may be a resistance wire, or a component such as a thermistor. The heater is located in a region of non-uniform or varying magnetic field e.g. near the edge of the magnet pole. The heater 7 heats the gas and as a result changes the magnetic susceptibility of the oxygen. This creates a net force on the oxygen in the non-uniform field and hence a magnetic wind. This magnetic wind changes the temperature of the heat sensor, allowing the concentration of oxygen to be determined. The heater and heat sensor may be enclosed in a gas flow channel 13a comprising a portion of large cross-section and a portion of smaller cross-section. The output of the heat sensor may be passed to a band pass filter (see figure 5B) to remove effects from ambient temperature, or the analyser may also comprise a dummy magnet portion with a second heat sensor to cancel ambient temperature variations. Alternatively, the heat sensor may form part of a bridge circuit. In alternative embodiments, pairs of magnets, heaters or heat sensors may be used to improve the accuracy.

Title: Minimisation of interference in cellular communications systems
Inventor: SANCHO FERNANDO
IPC: H04W72/08
Filed: 2001-08-18
Abstract: A method of minimising interference by transmissions from an antenna of a first base station detected by a mobile station located in the coverage area of a neighbour base station. The beam pattern of the antenna of the first base station is calculated, and at least one neighbour base station whose coverage area partially overlaps that of the first base station is identified. The strength of a ray of the beam pattern directed at the neighbouring base station is calculated. A mobile station reports carrier-over-interference (C/I) levels within the coverage area of the neighbour base station, preferably over time, the interference originating from carrier signal of the first base station. The C/I level is compared to a pre-set threshold to give a desired attenuation level of the first base station's carrier signal. This is then used to adjust the beam pattern, preferably using down-tilt, giving a second ray to replace the first ray. A weighting factor for the number of mobile stations served by neighbouring base stations may be used in the adjustment factor, as may be the variation in the C/I measurement reports and the relative heights of the base stations.

Title: Engine exhaust system with U-shaped section of larger internal diameter than other sections of the pipe
Inventor: NAITO TAKAHIKO
IPC: F01N1/08
Filed: 2001-09-04
Abstract: An engine exhaust system comprises a generally U-shaped crook or bend 2c at the mid section of the exhaust system pipe 2.

Title: Hair removal device
Inventor: MILLS DESMOND
IPC: A45D26/00
Filed: 2002-07-18
Abstract: A hair removal device, comprising a housing 2 having an aperture 4 at one end, through which arms 5 of a tweezer may extend. Pressing buttons 6a and 6b situated on the body of the housing 2 causes members to come into contact with the tweezer arms 5 and so that the tweezer arms are pushed towards one another. This causes the tweezer arms 5 to grip hair that is positioned between them. Power may be selectively supplied to the tweezer arms 5 by using a control 9. When the power is supplied to tweezer arms 5 that are gripping hair the power is transmitted to the hair with the result that it causes weakening of the hair consequently when the tweezer arms are retracted back into the housing, this weakened hair is pulled from its associated hair follicle. The hair removal device allows for selection of power modes, for example, being powered by a mains supply, by a battery or optionally, there being no power supplied so that the device can be used simply for plucking hairs from the body.

Title: Registration of multi-modality data in imaging
Inventor: BEHRENBRUCH CHRISTIAN PETER
IPC: G06T7/00
Filed: 2002-07-19
Abstract: A method of registration of a functional emission image to another image, e.g. a structural or anatomical image, is disclosed. The method utilises a set of three images captured using different techniques, e.g. SPECT for functional emissions, SPTCT for transmission and x-rays for structure. The first and second images have a known positional relationship and areas of interest are distinguished in them; this may take the form of processing the emission image to mask out regions of the background and lungs identified in a corresponding transmission image. The third image is then registered to the first image using one of these areas of interest; or, only areas which are not masked out in the emission image are matched to areas in an x-ray image. The x-ray image and masked emission image may then be displayed in superposition.
