摘要： A system for the discontinuous transformation of visual images utilizing a variable delay. The visual image to be transformed is first converted to a time-varying video signal. This signal is then converted to a digital signal which is fed to a delay circuit whose time delay can be instantaneously varied. The exemplary delay circuit shown includes a random access memory which is usedc to store and release the stored digital information as a function of the desired delay. The output of the delay circuit can then be inverted to achieve the transformed visual image.

摘要： A ribbon assembly and a method of forming same for use in a ribbon loudspeaker which has an elongated electrically conducting ribbon, a magnet means for producing a magnetic field parallel to a mean plane through and directed transversely to the ribbon, and means for generating a varying electrical current through the ribbon. The ribbon assembly includes a wafer board having an elongated aperture and means for mounting the ribbon across the aperture, to electrically conducting pads at either end thereof such that the clearance between the elongated edges of the ribbon and the adjacent elongated ribbon facing edge of the aperture, are less than 1% of the ribbon width. A pair of elongated side rails are removably disposed along each elongated side of the aperture to form ribbon facing edges of the aperture.
