  • Patent number: 4020279
    Abstract: An adjustable anamorphic transformer comprises a source of video signals, which are primarily -- but not exclusively -- images of a human brain. The video signals have their horizontal and vertical synchronizing signals separated out and then independently processed. The video signals themselves are amplified with an automatic gain control. An electronic means jointly responsive to the separately processed horizontal and vertical signals controls the gain of the video amplifier. Other electronic means separately responsive to the horizontal and vertical signals independently control, in X and Y axes, the expansion of images produced responsive to the video signals.

  • Patent number: 3940560
    Abstract: A sound pick-up and reproducing system, comprising a first and a second pair of directional microphones respectively disposed at a first and a second given distance from the sonic scene to be transmitted, said second distance being greater than said first distance, said four microphones being closely coupled; the system is characterized in that the spacing between the microphones of the second pair is substantially less than that between the microphones of the first pair, and in that the angular divergence between the sound pick-up axes of the second pair is substantially less than the angular divergence between the sound pick-up axes of the first pair of microphones.
