  • Patent number: 5414429
    Abstract: A device for converting data for display on at least one television screen associated with a videographic memory, the output signals of the radar comprising at least one videographic signal and scanning data, the device comprises a processor for processing the different radar output data, an analog/digital converter for digitizing the videographic signal, a videographic signal converter for compressing the digitized videographic signal, a distance marker generator for generating distance markers, a polar to Cartesian converter for converting the standard of the coordinates of the data contained in the signal from a polar coordinate system into a Cartesian coordinate system, an intermediate memory for receiving and storing the compressed videographic signal and the distance markers, an output buffer memory for receiving and storing the output signals of the intermediate memory and the polar to Cartesian converter and an interface for controlling the memory as a function of the data contained in the buffer memo

  • Patent number: 5357255
    Abstract: This system for displaying data on a display unit comprising a television screen associated with a videographic memory, the data containing at least one videographic signal and scanning data, a pre-processing unit for reel time programming the output data of the radar, a threshold unit for thresholding the videographic signal from its background noise, and a digitizer circuit for digitizing the videographic signal after thresholding, a compression circuit for space-time compressing the videographic signal after digitization, a transmission device for proprietary serial data transmission of the scanning data, of the compressed videographic signal and of compression data, to the television display assembly unit, which comprises a decompression unit for decompressing the videographic signal and a converter unit for converting the standard of the coordinates of the data contained in this signal, from a polar coordinates into a Cartesian coordinates with the aid of the compression and scanning data, and control de
