1. A data gathering system comprising:

  • a. a plurality of array terminals, each having a parallel to serial convertor means;

    b. each array terminal having a plurality of conductor means, each connected to at least one detector so that said detectors can be positioned in selected spaced relation, to sense at least one physical parameter, and to produce an analog signal indicative of said parameter;

    c. each array terminal having an input port and an output port, into each of which a multiple conductor cable is connected, said multiple conductors comprising signal and control conductors;

    d. means, including a plurality of selected lengths of said cable, to connect said array terminals in series connection, and to connect the last in series of said terminals to array controller means, said signal conductors connecting said parallel to serial convertor means in adjacent terminals;

    e. means, in said array controller means, to signal said terminals, by a coded signal on said control conductors;

    f. a plurality of means in each array terminal, each one in circuit with one of said detector means to amplify, digitize to 1 bit said analog signal, and to store said digitized signals in said parallel to serial convertor means;

    g. means, on command from said array controller means, to read out and transmit said 1 bit digitized signals, stored in said convertor means, to the convertor means in the next in series array terminal,whereby said digitized signals are transmitted sequentially through each of said convertor means to said array controller means.
