Abstract: A major/minor loop bubble domain memory system maintains the non-volatility of data when subjected to a power on-off-on sequence. A bubble domain shift register is associated with the major/minor loop array and indicates when a block of data in the major loop is in position to be transferred into the minor loops. The length of the shift register is related to the propagation delay of the path over which a bubble is propagated along the major loop from a minor loop read transfer switch to the write transfer switch for the same minor loop.

Abstract: ?U9-88-008 A track-seeking system for an optical disk using a velocity control loop with partially-digitized velocity measurement. A quadrature signal is generated based on summing the halves of a position error signal to give directionality to track-crossing counts. A so-called piggy-back construction, wherein a fine positioner is carried by a coarse positioner, is employed. Feed-forward controls are provided from the fine to the coarse positioner. At track-capture time, the dynamic range of the fine positioner is momentarily increased.

Abstract: A method and apparatus for the point plotting and rearrangement of graphical data from a coded source into a buffer for raster type display. The execution of a graphic order in a stored program controllable graphics terminal are represented by a line generating a sequence of X Y coordinate values, which values are to be plotted or displayed. The points are plotted into a work organized memory array in the form of topologically adjacent rectangular subarrays. These subarrays are then transformed into linear arrays. In order to conserve memory they directly replace the previous topologically adjacent subarrays in the memory. The linear arrays may then be accessed a word at a time and applied to the raster display.
