Title: Superimposing text on an image wherein pixel values of pixels to be overlaid a re transferred to neighbouring pixels
Inventor: CRABTREE JOHN CHRISTOPHER RALS
IPC: G06T11/60
Filed: 2002-08-14
Abstract: A method for processing an image is provided. A first image and a second image are provided, and donor pixels in the first image are located which correspond to active pixels on the second image. One of the channels of the first image is selected and a donor pixel is chosen. The pixels of the first image are searched in the region of the donor pixel in order to determine suitable receiver pixels. A transfer of luminance is performed from the donor pixel to these receiver pixels through the receiver pixel array. A second donor pixel is then selected, another search is carried out and a transfer of luminance is again performed. This process is then repeated for each donor pixel. Another embodiment transfers colour values from a donor pixel to a receiver pixel rather than luminance values. By preserving the aggregate RGB values for local groups of pixels, local groups have the same tone/colour appearance as the original local groups. The invention allows combining of text with images such that image information which underlies the superimposed text is preserved.

Patent GB-2396013-A (GB)
Title: Processing seismic data to remove swell noise
Inventor: ZEROUK KAMIL
IPC: G01V1/36
Filed: 2002-12-04
Abstract: The invention relates to processing seismic data that contains both a desired signal and swell noise caused by wave action on the receiver. The method is applicable to seismic data is in the frequency-space domain method and comprises determining a signal-only prediction filter from the seismic data at a first frequency at which swell noise is not present, and applying the prediction filter to seismic data at a second frequency at which swell noise is present. This attenuates swell noise in the seismic data at the second frequency. In one embodiment, the prediction filter for a frequency fL, the lowest frequency at which swell noise is present, is determined from seismic data at frequency fH+1, where fH is the highest frequency at which swell noise is present. The prediction filter for a frequency fL+1 is determined from seismic data at frequency fH+2, and so on, so that the prediction filter for frequency fH+1 is determined from seismic data at frequency f2H-L+1. In this way, the prediction filter for each frequency in the swell noise range is determined from seismic data outside the swell noise range, but at a frequency close to the swell noise range, and this provides effective extraction of the signal and attenuation of the swell noise. Furthermore, no prediction filters is applied to data of more than one frequency, so that an error in the determination of a particular prediction filter will have only limited effect on the processed data.

Title: Wireless communication unit and wideband voltage controlled oscillator therefor
Inventor: CORSE NIR
IPC: H03B5/12
Filed: 2003-04-29
Abstract: A wireless communication unit (100) comprises a voltage controlled oscillator (123) having an active device (450) operably coupled to a first variable capacitance (425) to provide a variable capacitance value based on an applied steering line voltage, and a feedback network comprising a resonator (475), operably coupled to an output of the active device, for feeding power back to an input of the active device to sustain oscillations (123). Notably, a second variable capacitance is operably coupled to the steering line (405) and located adjacent to the resonator (475). The provision of a second variable capacitance located adjacent to the resonator enables a VCO design to operate over a wider bandwidth with the same tuning voltages, say around 15% of the VCO's centre frequency. This is achieved due to gain margin tuning applied to the resonator and second variable capacitor of the VCO circuit.

Title: An RF transmitter with optimal control of amplifier bias with respect to efficiency and adjacent channel power
Inventor: CUNNINGHAM ANDREW
IPC: H03F1/06
Filed: 2003-10-07
Abstract: A mobile 'phone transmitter includes an RF amplifier 18 gain-stabilized by a feedback loop 22,26,28,14. The adjacent channel leakage ratio (ACLR) of the output signal 24 is computed in control circuit 20 (figures 2 or 3) and the bias input of the amplifier 18 is then adjusted so that the ACLR (ACPR) is met but not significantly exceeded, thereby ensuring compliance with ACLR standards while minimising power consumption. The ACLR ratio is computed using logarithmic generators (figures 2 or 3). The ACLR ratio may be computed as (a) the ratio of the total output power to the adjacent channel power or (b) the ratio of the desired channel power to the adjacent channel power. The feedback loop maintains the output level despite alteration of the amplifier's gain due to bias changes.
