  • Magneto-optic bubble domain histograph
    Patent number: 4087809
    Abstract: A display system for providing a real-time, dynamic presentation of an analog signal waveform is disclosed. The system includes an A-D converter that is coupled to a 1-out-of-M decoder that, in turn, drives a serial string of bubble domain generators. The bubble domain generators generate moving columns of bubbles, the heights of the columns representing the amplitudes of the analog signal waveform at each of the associated sample times. The bubble domain memory plane is of a construction to permit the columns of moving bubbles to appear as moving columns of bright spots when seen by an observer utilizing a plane polarized light beam and an analyzer.

  • Best match content addressable memory
    Patent number: 4084260
    Abstract: A method of and an apparatus for determining the best match, i.e., minimum Hamming distance, between a search word and a plurality of file words is disclosed. The method involves simultaneously comparing the search word to a file word and to a match word. If the comparison indicates that the file word is a better match than the match word, the file word becomes the match word and the next file word is compared to the new match word. The operation continues until all the file words have been operated upon such that the last match word becomes the best match word.
