  • Patent number: 8049657
    Abstract: Sub-aperture processing is carried out. Within each sub-aperture, range compression and a correction for the target range variation are carried out. Baseband azimuth scaling is used for processing the azimuth signal, wherein a long azimuth reference function and thus a wide azimuth dimension are prevented. The scaling range is not constant and depends on the range, which is not equal to the original range vector. It is calculated such that, in combination with a subsequent derotation step, constant azimuth scanning is achieved for all ranges. The selected derotation function, which is applied in the azimuth time domain, makes it possible for all the targets to be in base band, in this way varying the effective chirp rate. Since the phase is purely quadratic because of the azimuth scaling step, it is thus possible to use an optimal filter which takes account of the effective chirp rate. IFFT results in a focused image, and a final phase function in the time domain allows phase maintenance.

  • Patent number: 8049002
    Abstract: Processes for the synthesis of lipochitooligosaccharides were developed. A fully acylated oligoglucosamine precursor is prepared and reacted with a glucosamine monomer that has an amine protecting phthaloyl group. With removal of the phthaloyl group, a fatty acid may be added on the terminal glucosamine unit, forming a lipochitooligosaccharide. The processes can be adapted for use on a commercial scale.

  • Patent number: 8049171
    Abstract: A sensor device of the type for sensing incident radiation by charge generation, has a substrate within which charge may be generated by incident radiation. A plurality of electrodes are arranged to cover an image area of the substrate and are selectively connectable to supplied DC voltages such that an electric field is created across the image area to sweep charge across multiple electrodes from the image area to an output. The voltage applied to one of the electrodes may be a voltage of a level so as to present a barrier to charge within the image area. The sensor thus has a variable sample area defined by the barrier voltage level.
