Abstract: A primary processor provides control, address and data signals to a shadow comparison ASIC which also receives corresponding signals from a shadow processor running in delayed lock step with respect to the primary processor. The primary processor is coupled to a system CPU bus which communicates through a memory interface with a DRAM memory. An EDC circuit generates EDC syndrome bits with respect to data written by the primary processor into the memory through the interface. The EDC syndrome bits are stored in memory along with the data. The shadow comparison ASIC includes an identical EDC circuit for generating comparable syndrome bits from the data transmitted from the primary processor to the memory when in the write mode and from the data transmitted from the memory to the primary processor when in the read mode.

Abstract: An inorganic reinforcement component, such as fiberglass, is reclaimed from a scrap material including a vaporizable organic resin, such as epoxy, by heating the scrap material in an elongated, rotary furnace to a temperature above the vaporization point of the organic resin and below a point where the structural integrity of the reinforcement material is degraded. A purge gas flowing through the furnace countercurrently to the moving bed of scrap material sweeps away volatized gases, the organic reinforcement component is withdrawn from the outlet end of the furnace and a stream of combined gases including the purge gas and the volatized organic material is withdrawn from the inlet end of the furnace.

Abstract: Apparatus for selectively extracting, magnifying and juxtapositioning selected areas of a raster scan image relative to the primary image so as to permit an observer to better view selected areas of the primary image while still viewing the entire primary image. The apparatus essentially comprises means for sampling x and y radar address data and related video data, means for independently and selectively scaling and offsetting the address data for a primary image memory and for a local zoom memory and means for selecting the areas of the primary image that are to be magnified. The selected areas of the primary image are displayed at a rate defined by a zoom magnification factor, scaled and offset independent of the primary image--but relative to the local zoom area, and displayed by extracting the data from the local zoom memory, rather than the primary image memory, as the display raster scans the areas of the screen where the zoom image is to be displayed.

Abstract: A method and apparatus for pseudorandomly decrementing the intensity of data that is displayed on a raster scan display screen. The apparatus essentially comprises means for selecting and partially decrementing data from an image memory and means for controlling the rate at which the partially decremented data is written back into the image memory so that an apparently uniform phosphor decay rate is observed by a viewer.

Abstract: A Scanning Sonar Display System comprised of a TV monitor, a scanning mechanism with transducer, control logic with image memory and timing, a power source such as a 12 volt storage battery and a set of operator controls. The type of TV monitor used is well known and similar to those used by raster scan computer terminals. The scanning mechanism has a stepping motor with a 10 to 1 reduction cable drive system to rotate the transducer with home initializing contacts. The control logic includes two counters used as image memory address registers. The first, the refresh counter, is used for reading the image memory during refresh and for determining the horizontal and vertical sync for the TV monitor. The second, the entry counter, is used for writing sonar and depth data into the image memory and is also used for control of the stepping motor. Home initializing contacts are used to initialize this counter.

Abstract: A method and apparatus whereby an auxiliary yoke is used in conjunction with a CRT display to correctively deflect the electron beam to a true position within each pixel of a graphics figure, as the graphics figure is displayed on the CRT's screen. The apparatus thus increasing the display's resolution within each pixel so as to permit the smoothing of the displayed graphics figures.The improved resolution being achieved via a four bit binary position correction code, three bits of which are stored in the image memory at those memory addresses corresponding to the coordinates of the pixels that comprise the graphics figure, and one bit of which position correction code is stored at the immediately preceeding memory addresses. The entire position correction code in turn being decoded as the image memory is read and used to drive one or the other of the x and y coil pairs of the x-y auxiliary yoke.

Abstract: A system for expanding a dot-matrix for characters being displayed on a television raster scan display to improve the readability and resolution of displayed characters without a corresponding increase in the size of the Read-Only Memory (ROM) employed to generate the pattern of dots defining the characters. This result is accomplished by first displaying the identical dot-matrix stored in the ROM for each character in each row of characters to be displayed on the first pass of the raster scan. On the second pass of the raster scan, which is interlaced between the lines of the first pass of the raster scan, a new dot-matrix is inserted according to a predetermined logical real time comparison of the dot matrix of the adjacent rows of the dots produced during the first raster scan.
