Abstract: A method of and an apparatus for reading out the information that is stored in a magnetizable layer that is formed of a thin film in which data are stored as inverted Neel wall sections about associated Bloch-lines along a cross-tie wall. The apparatus utilizes a magnetizable layer which is configured into a strip whose two opposing edges are, along its longitudinal axis, formed into mirror-imaged, spaced-apart, repetitive, asymmetrically-shaped patterns which repetitive patterns are formed of successive narrow portions that form wide portions therebetween. The repetitive patterns, when suitable magnetic fields are coupled thereto, form a cross-tie wall along the longitudinal axis of the strip while structuring the cross-ties along the cross-tie wall at the narrow portions and the Bloch-lines along the cross-tie walls and between the adjacent narrow portions. One of the repetitive patterns is configured into a sharp film whose longitudinal axis is transverse the strip's longitudinal axis and whose transverse axis is along the strip's longitudinal axis. The sharp film, in the area extending beyond the strip's two opposing edges, comprises an open flux path film that possesses the characteristic of shape anisotropy providing a magnetic easy axis that is generally oriented along the sharp film's longitudinal axis and along which the sharp film's remanent magnetization resides wherein for all points on the sharp film's edge the angle .beta.' between the sharp film's edge and the sharp film's longitudinal axis is equal to or greater than 0.degree. and less than 45.degree.. Also disclosed is a detector that is associated with the sharp film for reading out the orientation of the sharp film's remanent magnetization along the sharp film's easy axis.

Abstract: A method of and an apparatus for counting is disclosed. The counter includes a generator of cross-tie, Bloch-line pairs and a shift register of N stages or memory cells along which the cross-tie, Bloch-line pairs are propagated or replicated into a detector. The method includes coupling a series of bipolar push-nucleate replicate signals, each one of which produces a cross-tie, Bloch-line pair in the adjacent downstream memory cell along the shift register. When the shift register is filled, a cross-tie will appear in the detector. This provides an output signal indicating that the N memory cells have been filled by the N replicate signals.

Abstract: Disclosed is a cross-tie wall memory system for the generating, propagating and detecting of binary data represented by the presence or absence of cross-tie, Bloch-line pairs along a cross-tie wall in a thin magnetic data track. The system includes a three-level shift register structure comprised of the following layers: first and second substantially similar, serrated-edged current conductive striplines and a serrated-edged thin magnetic layer data track. The shift register is terminated on one end by a cross-tie, Bloch-line pair generator and on the other end by a cross-tie detector. A data word is stored in the data track between the generator and the detector and is shifted through the detector for readout of the stored data word. The first and second serrated-edged striplines are formed of alternate wide-narrow portions with the wide portion of one stripline oriented above/below the narrow portion of the other stripline. Current signals alternatively coupled to the first and second striplines generate drive fields of differing intensities in the plane of the inductively coupled data track for propagating the cross-tie, Bloch-line pairs therealong.

Abstract: A data track formed of a strip of magnetic film having substantially zero uniaxial anisotropy, i.e., isotropic, for a cross-tie wall memory system is disclosed. The data-track-defining-strip of isotropic magnetic film utilizes its shape, i.e., its edge contour induced anisotropy, rather than its easy axis magnetic field induced anisotropy, to constrain the cross-tie wall within the planar contour of the film strip. The use of the shape induced anisotropy of an isotropic strip of magnetic film permits the use of nonlinear, i.e., curved, data tracks which curved data tracks were not permitted by the prior art cross-tie wall memory systems that were limited to the use of anisotropic magnetic film.

Abstract: The method of and a configuration for reading out the information that is stored in a cross-tie wall memory system is disclosed. The apparatus utilizes: a continuously, relatively long, sense line that is aligned along and straddles the cross-tie wall; a first polarity hard axis drive field H.sub.Tt that passes, if in existence, a stored-1-representing-Bloch-line from a memory segment along the cross-tie wall into, along and past the continuous sense line; a second polarity hard axis drive field H.sub.Tn that nucleates many Bloch-lines at once along the cross-tie wall in the area of the sense line for causing the nucleating Bloch-lines to induce in the sense line an output signal that is indicative of the change in polarity of the Neel wall vectors within the cross-tie wall in the area of the sense line and, accordingly, whether or not a stored-1-representing-Bloch-line had been stored previously in the memory segment.

Abstract: A system for optically correlating two signals, e.g., radar, sonar, etc., incorporating both time shifts and doppler shifts is described. The correlation of the signals is produced as a two-dimensional distribution of light on a light detector/display plane wherein the amplitude of the light distribution is proportional to the correlation of the two signals as a function of relative time shifts, .DELTA.t (X direction), and relative doppler shifts, .alpha..omega. (Y direction), between the signals. Doppler shifts are introduced into the processor by the incorporation of a channelized cylindrical lens in one signal channel while using a cylindrical lens in the other signal channel.

Abstract: An apparatus for and a method of storing binary data in a thin ferromagnetic film strip as the presence or absence of Bloch-lines without the presence of cross-ties. The apparatus utilizes a serrated strip of isotropic magnetic material that is formed in the shape of a series of contiguous disks. Each pair of contiguous disks is coupled by a narrow section of magnetic material that functions as a "door" between adjacent disks through which the Bloch-line defining datum bit may be propagated when subjected to the appropriate drive fields.

Abstract: A fiber-optic switchboard is developed consisting of a plurality of n input fibers, n input lenses, n light deflecting elements, n relay lenses, a multifaceted reflector, m output lenses, and m output fibers. Each input lens causes an image of the end of the corresponding input fiber to fall on its deflecting element, while each relay lens causes an image of the corresponding deflector element to fall on the proper facet of the multifaceted reflector. Each output lens causes an image of the multifaceted reflector to fall on the face of the corresponding output fiber. The output lenses are placed such that each deflecting element is capable of directing light through any output lens and into the corresponding output fiber.
