  • Publication number: 20250084100
    Abstract: A method for preparing a nitrogen-containing polycyclic fused ring compound of formula I, and an intermediate thereof are provided. By this method, the compound of formula I can be produced on an industrial scale without column chromatography separation, purification steps such as silica gel column chromatography, or hydrogen. In addition, the preparation method effectively uses positional isomers IIIA and IIIB, and improves the yield of a target product from being adversely influenced by discarding positional isomer IIIA.

  • Patent number: 7973705
    Abstract: A plotting system and method for plotting radar and/or sonar signals on a bump map, with a simulated height of each data point representing a corresponding signal strength. The plotting system may comprise a processing device for associating particular signal strengths with normal vectors. The normal vectors may be used to determine the simulated heights to be illustrated on the bump map. The plotting system may also comprise a display for graphically displaying the bump map. Furthermore, the processing device may also associate particular signal strengths with particular colors, such that both color and simulated height may illustrate the strength of the plotted signals.
