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 specially designed ribbon for a ribbon loudspeaker is disclosed which prevents ribbon snaking associated with prior art corregated ribbon. The elimination of snaking enables the use of extremely small gaps between the side edges of the ribbon and the magnetic pole pieces which in turn greatly reduce transient distortion of high fidelity sound. Relatively large amplitude corregations are formed within suspended terminal ribbon portions and substantially smaller amplitude corregations are formed within the suspended centralized ribbon portion.

摘要： A stereophonic sound system has the conventional components of a stereo pre-amplifier, to receive and amplify left and right audio signals, originating from left and right channel microphones, and feed left and right power amplifiers for left and right loudspeakers and additionally has left and right attack separator circuits (6+18, 8+20) connected to receive input audio signals from the pre-amplifier (70) and acting to separate the attack components from the steady-state components of the input audio signals, the steady-state components being fed to the left and right power amplifiers (42, 44) and the attack components being fed to an attack correlator (30) which compares the arrival times of the attack components from the left and right audio signals and calculates an azimuth angle corresponding to the point of origin (8) of the original sound, an attack distributor (40) is connected to the outputs of the correlator and distributes transient attack signals to one of a series of small power amplifiers (46, 48, 50, 52) which amplify the transient attack signal for a respective one of a series of high frequency speakers (58, 60 62, 64) arranged between the main left and right speakers (54, 56); by this means the attack portions of the original audio signals can be perceived by a listener as originating from points spread out between the main speakers, which points individually have a relation to the azimuth angle of individual sounds relative to the microphones.

摘要： A serial cross-correlator having a pair of input ports (L and R). One of these ports (L) is connected to a first band-pass filter network (63) which is in turn connected to a digital Hilbert transformer (60). The other of the input ports (R) is connected to a second band-pass filter network (64) which is in turn connected to fixed delay (65). The output of the Hilbert transformer is connected to one input of a multiplier (66) while the output of the fixed delay is connected to the other input of the multiplier; and a low pass filter network (67) is connected to the output of the multiplier. The Hilbert transformer produces a 90.degree. phase shift for input signals on line (61) from input port (L) relative to input signals on line (62) from input port (R) and the delay compensates for the delay in the Hilbert transformer so that signals reaching input port (L) are phase-shifted relative to the signals reaching input port (R) and the phase-shifted signals are multiplied with the other input signals to produce an output signal (DX) representative of the direction and magnitude of an arrival time difference between the two input signals.
