Abstract: A communications channel may radiate energy undesirably, for example in the form of electromagnetic radiation, when a communication signal transmits over the communications channel. Processing the signal before and after transmission on the communications channel can reduce the level of radiated energy. Signal processing in advance of transmission over the communications channel can transform the communication signal into a waveform that has a reduced propensity to emit radiated energy during transmission over the communications channel. Exemplary signal transformations can involve applying either frequency-selective or broadband attenuation to the communication signal. Following transmission of the waveform over the communications channel, the original communication signal can be restored via reversing the signal transformation. The reverse transformation can comprise applying frequency-selective gain or broadband gain to the transmitted waveform.

Abstract: Proportional spacing of characters, for example by a laser-xerographic printer, is achieved using a character generator memory, for example a random access memory (RAM), to store the characters of a font in a plurality of variable-size binary matrices. Each column includes at least one parity bit and at least two pitch bits or end of character (EOC) bits. After a character matrix is selected for printing: the columns are transmitted sequentially from the RAM, the bit patterns are decoded as valid and invalid EOC indication signals or as valid and invalid NON-EOC signals, and the parity of each column is checked. Also, stop printing circuitry inhibits operation of the dot matrix printer when the parity checker indicates no error but the pitch bit decoder derives an invalid EOC or NON-EOC SIGNAL.

Abstract: A character display system is disclosed which provides displays of characters of variable size. A diddle raster scanning technique is used to display each character in its entirely before proceeding with the display of the next character. The size of the character is increased by increasing the size of the diddle raster scanned. In order to improve the appearance of larger point size characters, each character stroke is repeated a number of times N, where N increases with increasing point size.A circuit (112) provides an indication of the size of the character to be displayed. This indication is used to address a ROM (146) which contains control information (D1-D5) therein. A portion (D2, ) D3, D5) of this information controls the size of the diddle raster scanned, and another portion (D1) provides the number N indicating the number of times each character stroke is to be repeated. A video generator (114) generates a video signal on the basis of this number N and various character codes supplied to it.

Abstract: A digital display circuit for use with a video game or other displays fabricated as an MOS integrated circuit is described. The circuit permits the simultaneous display of many different patterns (and the simultaneous display of the same pattern) at any locations on a raster scanned cathode ray tube. Content-addressable memories are employed to compare the contents of a digital beam location counter with desired object locations. A random-access memory is then used to address a pattern library where each line of the patterns is stored. When more than one pattern is displayed at the same location, counting in the digital beam location counter is delayed to permit accessing of more than a single pattern line from the pattern library. A displacement counter is employed to store a count representative of the displacement between the actual beam position and the contents of the beam counter. The beam location counter is incremented at a faster rate during non-display periods to compensate for delayed counting.

Abstract: An optical printer comprises a mechanical scanner, which scans a modulated light beam across a recording medium in a main or horizontal direction at a fixed speed. An acousto-optic deflector performs auxiliary scanning of the beam in a vertical direction onto the mechanical scanner at a constant rate and is connected to a deflection signal generator. The deflection signal generator adjusts the stroke length of auxiliary scan in accordance with the magnification ratio and simultaneously adjusts the frequency of auxiliary scanning by the reciprocal of the magnification rate of the character to be printed. Furthermore, optical density is maintained constant for various character sizes by providing auxiliary gate pulses proportional to the square of the relative character size, which are AND gated with a character information signal to effect a light modulation signal for modulating the beam.

Abstract: A method and apparatus is shown for improving the clarity and character density on a cathode ray tube (CRT) display in which characters are formed row by row from discrete character elements in row and column coordinate matrices. Unblanking signals form the discrete character elements no less than two matrix spaces wide every time an unblanking signal is applied. This technique results in a much crisper appearance to the characters on the screen and permits as many as 128 characters per line using a low cost commercially available television (TV) monitor. A random access storage is used to store dynamically the addresses of positions (locations) of a read only store corresponding to characters to be displayed. The read only store (ROS) contains indicia corresponding to the discrete character elements of a plurality of characters, one set of indicia for each character in the desired character set.

Abstract: A printer responds to channel commands including coded data received over a channel from a data processing unit by printing characters represented by the coded data using an electrophotographic printing arrangement. The coded data received by the printer is first translated into corresponding graphic codes or addresses by a translate table employing a predetermined translation code, following which the addresses are used to locate sets of character image bits stored within a plurality of character generator modules. Each set of character image bits is used to modulate a laser scan of a printing drum to effect printing of desired characters. Both the translate table and the character generator modules are program alterable, and the data stored therein can be loaded directly from or changed in response to data and instructions from the data processing unit.

Abstract: In a light scanning recording or displaying system, a synchronizing light beam is separated from a signal light beam used for recording images or display utilizing the difference in wavelength of the two light beams. The synchronizing light beam and the signal light beam are produced by different light sources of different wavelength and made to advance in the same direction to be reflected and deflected by a light scanning means such as a rotating mirror together in the same direction. After both the light beams are deflected by the light scanning means, the two beams are divided by use of a prism, a holographic plate or a dichroic mirror.

Abstract: Intermixing of line heights in a buffered printer is accomplished by storing a different byte in a forms control buffer for each line of coded character data in a page to be printed. As the coded data of each line is advanced for printing by an arrangement which modulates a laser beam during scanning across a printable medium to effect the printing, the byte within the forms control buffer corresponding to the line about to be printed causes selection of the number of scans of the laser beam to be used in printing the line, thereby determining the height of each line independently of the other lines in the page. Blank lines in the page are formed by channel commands to the printer which instruct an address register associated with the forms control buffer to be incremented to cause skipping to a particular channel number identified by one of the bytes in the forms control buffer or to cause spacing by a specified number of lines.

Abstract: In a buffered printer in which lines of character code bytes representing characters to be printed are translated into lines of graphic code bytes by a translate table, assembled into a page format in a page buffer and applied to a character generator module to select sets of character image bits in storage locations within the module corresponding to the graphic code bytes, the selected sets of character image bits being applied to modulate a scanning laser beam to effect printing of the desired characters, each line of graphic code bytes provided by the translate table is entered into the page buffer in a selected location determined by a channel command associated with the previously entered line. Each "write and no space" command accompanying a line of graphic code bytes stored in the page buffer results in the immediately following line of graphic code bytes being stored in the same location. The two different lines are combined in accordance with a merge algorithm.

Abstract: In a printer in which character code bytes representing characters to be printed are translated into graphic code bytes, assembled into lines and pages, and thereafter used to select character image bits which are applied to modulate a scanning laser beam and thereby effect printing of the characters, the pitch of each character is determined independently of other characters in each line being printed by pitch bits included in the sets of character image bits. As each scan line of modulation bits from a set of character image bits is selected for use in modulating the laser beam, the pitch bit included within the bits is examined to determine whether the width of the charactor is to be a maximum or some value less than the maximum. For the maximum width all of the modulation bits are applied to modulate the laser beam, while for a character cell width less than the maximum, only a selected number of the modulation bits are used to modulate the laser beam.

Abstract: An apparatus for moving film through a projection or camera system utilizing continuous, uninterrupted motion of the film. Conventional sprocketed film is moved from reel to reel at a constant velocity. The image of the film frame passing over the film projection gate is projected upon an oscillating mirror mechanism which is driven synchronously with the motive force for the film strip. The oscillating mirror pivots at an angular velocity which stabilizes the image of the film frame, the mirror returning to its initial position during a small interval of the total time the film frame passes over the projection gate. A shutter periodically interrupts the light passing through the film frame to allow the mirror to return to its initial position where it becomes synchronized with the succeeding frame image.

Abstract: An apparatus is disclosed for displaying subscript and superscript characters on the screen of a cathode ray tube. The encoded characters are selectively read from a memory which also provides two extended level outputs relating to the subscript and superscript features. In response to the readout of a superscript character from memory, a superscript signal, at the related extended memory output, is fed to an amplifier which, in turn, drives a superscript coil positioned about the neck of the cathode ray tube. This superscript coil generates a flux which reacts with the flux generated by the tube's vertical deflection coil during readout of the selected character thereby raising the position of that character on the screen. Correspondingly, a subscript signal at the related extended memory output results in the generation of a magnetic flux which reacts the vertical deflection coil field during readout of the selected character thereby lowering the position of that character on the screen.

Abstract: Apparatus for reproducing characters from cathode ray tubes wherein a beam is deflected onto alpha/numeric characters occupying a selected area of a font. The beam is deflected by relatively high speed linear vertical strokes which are displaced horizontally by a slower speed stroke advance waveform and each scan is positioned relative to one of the selected areas. The vertical linear strokes of the beam are at a variable rate and the vertical strokes are terminated by time interval pulses at an amplitude corresponding to the area height of the font character. The rate of the strokes is determined by the time interval pulses which in turn are regulated by point size control selection means. A resultant two level output signal representative of the successive selected characters controls another cathode ray tube, the scanning of which is identical to that of the first cathode ray tube.
