  • Patent number: 5029110
    Abstract: An automatic data plotting apparatus consists of three main parts: a processor; a serial and parallel interface; and a plotter. The plotter is a flat-bed X-Y plotter. The data processor is programmed to handle one or more data inputs and instruct the plotter to record information relating to the data inputs on a plot. The processor translates the incoming data into times, bearings, tracks and any other characteristics. A pause facility is provided to suspend plotting, the incoming data being stored in a data store while the pause facility is in operation and being recorded on the plot when the pause is discontinued. An automatic data plotting apparatus provides a focal point at which incoming information can be co-ordinated and displayed. The displayed information can then be evaluated and/or stored for later analysis.
