  • System for spatially and temporally transposing data words arrayed in periodically recurring patterns
    Patent number: 4602283
    Abstract: A train of incoming data words, specifically digitized video samples arrayed in frames of Y lines of X pixels each which have already undergone a 2-dimensional spatial transformation, is scrambled by being divided into Z sequences (frames) whose data words are temporarily written in respective cells of Z.sup.2 storage units of a memory of dynamic-RAM Type. The Z.sup.2 storage units, each divided into Z sections, are read out in cyclic-succession--at a rate of one cell per unit--and each cell is reloaded immediately after being vacated. Reading and writing occurs for one set of Z sequences in a first addressing mode, conforming to the order of arrival of the data words in the incoming train, and for the next set in a second addressing mode involving the grouping of homologous data words of respective sequences into successive series of Z data words each.

  • Method of undercut anisotropic etching of semiconductor material
    Patent number: 4600934
    Abstract: An etch stopped layer portion overlying a (100) or (110) major face of a diamond cubic semiconductor material is undercut anisotropically etched by orienting a side edge of the etch stopped layer portion which is to be undercut, at an angle to the most nearly parallel {111} trace on the (100) or (110) face. The etch time is further reduced by slotting through the etch stopped layer with slots oriented at an angle to the {111} traces on the underlying (100) or (110) face. Undercut bridge structures are formed by undercutting quadrilateral etch stopped layer portions from opposite sides of the quadrilateral or from the sides plus slots forming diagonals of {111} trace quadrilaterals having combined areas coextensive with the area to be undercut.
