Abstract: ZERO DISPARITY CODING/DECODING SYSTEM          Abstract In a digital transmission system, disparity is defined as the difference between the number of binary digits at each code state.  The generation of a block of binary digits having zero disparity possesses many advantages.  The present invention discloses coding apparatus for converting a block of binary digits having random disparity into a zero disparity block, and vice versa.  The coder accomplishes this translation by determining the disparity of the random disparity block and then selecting a bit position which divides the block into two digit segments each having half this disparity. Inversion of either digit segment generates a zero disparity block.  For decoding, data representing the bit position selected is transmitted along with the zero disparity block.  The binary digits previously inverted by the coder are then reinverted.  This coding/decoding technique is adaptable to any block size having an even number of binary digits.

Abstract: ABSTRACT          As a screen refreshing storage in a graphic processor a storage system 10 is presented that shows a very high access rate for data blocks used in graphic processors. For storing e.g. square data blocks, or for retrieving a row section of the display 23 only one storage access is required: this is a consequence of the specifically selected interleaving of the individual storage mo-dules 16 and of data editing for the respective access formats. The two-dimensional addressing for storing the data block di-stributes the individual elements of the data block to the modules in such a manner that the same storage addresses of all modules finally present a full picture of a row sectinn of the display. Between processor 1 or 7 and storage 10 a block buffer 4 is also provided operating in pingpong mode.

Abstract: ABSTRACT         A fiber optic energy sensor and optical demodulation system is disclosed wherein the signal energy to be sensed or detected causes an etched single mode fiber to be stretched or compressed which causes the optical path length for electromagnetic radiation traveling in the core of the optic fiber to change.  The change in optic path length modulates the electromagnetic radiation traveling in the fiber.  The optical demodulation system locates each energy sensor between the members of a pair of length limited Bragg reflectors formed inside of the optical fiber.  Each pair of reflectors as arranged, forms a Fabry-Perot type interferometer which only contains resonances for those portions of the electromagnetic spectrum in which the Bragg reflectors operate.  Since each energy sensor is located between the reflectors of a pair, then as signal energy is detected the sensor's resulting optical path length change causes the resonances of the Fabry-Perot interferometer to shift spectrally.  The system then partially demodulates this spectral shift using a second Fabry-Perot interferometer, called the analyzer interferometer, whose resonances have a spectral separation relative to that of the interferometer containing the energy sensor so as to cause amplification of the spectral shift.  The output of the combination of the energy sensor interferometer and the analyzer interferometer shifts spectrally more than the original spectral shift by an amplification factor given by equations presented in the detailed des-cription of the invention.  The system also allows the use of more than one analyzer interferometer, each causing different amplification.  The resulting amplifications can be arranged to provide outputs each of which corresponds to a separate digit of the number expressing the original spec-tral shift thus reducing the bandwidth of the electronic detectors and time demodulator.

Abstract: VIBRATING SCREEN WITH SCREEN DECK UNCLOGGING MECHANISM            ABSTRACT OF THE DISCLOSURE     A plurality of weighted springy arms are formed integral with, and so as to extend laterally, to one or both sides of, a resilient Mounting strip that is disposed beneath, and in contact with, the lower surface of the screen deck of a vibrating screen.  The intended vibrating action of the vibrating screen induces an oscillating movement of the weighted springy arms to effect a rapping action of the weighted ends of the arms against the undersurface of the screen deck to loosen material which may have lodged in or plugged the screen openings and to unclog same.     The resilient strips disposed on the extreme sides of the screen need only have weighted springy arms on the side thereof towards the central portion of the screen deck if space on the other side of the strip does not permit proper disposition and action of such an arm; while the strips disposed in the central section of the vibrating screen have arms extending from both sides of the resiliant strip.     The springy arms, are either cast in suitable rubber or plastic; with either integral weighted ends or with apertures disposed at their ends to receive suitably sized weights, formed from metal or other material of appropriate weight characteristics.  Alternatively the arms may be cast about a springy metal leaf to impart appropriate and desired spring characteristics to the arm to facilitate the coaction of the arm and screen deck and unclogging of the screen apertures.
