  • Patent number: 4365235
    Abstract: A Chinese/Kanji on-line recognition system consisting of four main sections, these being tablet electronics, a signal filter and segment integration unit, a base stroke classification unit and a symbol element recognition unit, and a symbol recognition output table. The tablet electronics provides pen coordinate signals and pen up/down signals which are applied to the signal filter and segment integration unit to define segments of strokes which correspond to continuous motion of a pen on a tablet in a fixed direction. The base stroke classification unit classifies the motion of the pen between pen down and pen up occurrences into one of 42 categories and also indicates if the stroke has crossed a prior stroke. This is then analyzed by the symbol element recognition unit which interprets the base strokes that have been recorded for the word and generates a sequence of symbol elements, referred to as "alphabet" components, that occur in this symbol.

  • Patent number: 4353061
    Abstract: An apparatus and method for forming scanned electron beam patterns which finds particular use in multiple beam cathode ray tubes. Instead of using the vertical line array of electron beam sources which is used in conventional multiple beam tubes, a two dimensional expanded beam array is provided. The expanded array is such that no two electron beams in the array are disposed in the same scan line and it is of a geometric shape having comparable length and width dimensions. In order to form characters or other patterns logic circuitry is provided to control each beam of the expanded array at respective scanning positions as the array is deflected or scanned across the screen of the cathode ray tube.

  • Patent number: 4353080
    Abstract: In a matrix array for the supply of an electrographic stylus writing apparatus, a plurality of styli are driven by short pulses through R/C networks. The styli are divided into subgroups and parallel capacitors connect the styli of each subgroup to a high voltage switch which is responsive to a capacitor pulse driver. Each stylus is also driven through a resistive line which completes the R/C circuit. The resistive lines are connected in parallel for similar styli of each group to a resistor enable pulsing circuit and all resistive lines are connected via isolation diodes to a resistor reset means. In operation, a short pulse from the capacitor driver circuit is applied to all the capacitors of a single group and an enabling pulse is applied to a predetermined single resistive line of each group so that the combined, enabled R/C circuit for a single stylus within one of groups is activated.

  • Patent number: 4342096
    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.

  • Patent number: 4338614
    Abstract: An improved electrostatic print head is disclosed comprising a corona source, an aperture mask, a slotted focus plane, and a back plane electrode for supporting a moving dielectric print medium. The aperture mask includes two rows of staggered circular apertures which are surrounded by individual aperture electrodes on the side of the mask facing away from the corona source. The side of the aperture mask facing the corona source has a continuous conductive layer thereon which is biased at a fixed potential. The aperture electrodes are selectively pulsed with a control potential to control the flow of ions from the corona source through the two staggered rows of apertures and the slotted focus plane to form any desired dot-matrix latent image on the moving dielectric print medium.

  • Patent number: 4323892
    Abstract: An alpha-numeric character generator arrangement having as a character store a "read-only" memory in which characters are stored in a character format composed of a co-ordinate matrix (e.g. a 7.times.5 dot matrix) of discrete character elements. One aspect of the invention resides in storing the descender letters g, j, p, q and y such that those elements forming the "tail" of the descender letter are stored in character element rows which in a given row addressing sequence for the store precede the character element rows in which the remaining elements for the descender letter are stored. Another aspect of the invention resides in addressing the character element rows of the character store in a partially cyclic manner such that descender letters are read-out for display in a "lowered", correctly aligned, position in a row of displayed characters. FIGS. 6 and 8 illustrate the invention.

  • Patent number: 4321626
    Abstract: Character codes having underline bits are read out of a memory (22). A character generator (18) generates character video signals in the form of horizontal scan lines corresponding to the codes. A line generator (30) generates line video signals corresponding to the underline bits. Where the apparatus is provided in a facsimile transmitter, the codes correspond to an identification of the station or the like and are entered into the memory (22) manually. Where the apparatus is provided in a facsimile receiver, the codes are received by a low speed modem (43) and stored in the memory (22). In either case, the receiver reproduces an original document in response to facsimile video signals with the identification characters, underlined where desired, superimposed on the document pattern.

  • Patent number: 4320395
    Abstract: A television-type system for displaying characters of an alpha-numeric test n a horizontal line moving across the face of a TV monitor includes pulse-generator-fed frequency dividers emitting pulse sequences of which three are transmitted via viewer-operated selectors for forming two frequencies f.sub.L and f.sub.Z applied to shift registers of a character generator to determine character height and width and another frequency f.sub.G applied to the stepping input of a delay-increment counter to determine character speed. In response to character codes transmitted from an input unit via a read/write memory, the character generator emits binary signals combinable with horizontal and vertical sync pulses into a video signal fed to the monitor. The counter is reset upon every horizontal sync pulse to have a modulus n equal to the contents of a total-delay counter stepped by the vertical sync pulses and reset after N of the same by a divder calculating the quotient N=T.sub.Z /T.sub.

  • Patent number: 4319077
    Abstract: A circuit for coded symbol conversion has first and second memories and a switching stage. Standard code characters from a keyboard are entered into the first memory and if the entered character is one which can be represented by a single binary word the switching stage enables transmission of the single word. If the entered character is one requiring more than one binary word for representation the input is transmitted to the second memory which generates an equivalent set of binary words to represent the symbol and further transmission is delayed until all such binary words are generated.

  • Patent number: 4298773
    Abstract: A method and apparatus for coding, transmitting, receiving, and displaying remotely or locally, all Arabic-Farsi characters or letters, basic arithmetic signs, numerals, punctuation marks and diacritical marks, as well as teleprinter operation commands in 5-bit standard Baudot codes. An Arabic-Farsi teleprinter similar in operation to the English teleprinter and compatible with the International exchange systems is provided without eliminating any letter forms. The teleprinter operation (the ability to compress the data into 5-bit characters) is based upon two basic criteria of the Arabic-Farsi languages, namely: (1) the form (start, middle, end or independent) of a character can be known if the preceding character and the following characters are known; and (2) there are six characters that are identical except for the presence or absence of a dot.

  • Patent number: 4286329
    Abstract: A character compaction and generation method and apparatus which is particularly adapted to the generation of complex characters such as Kanji characters. A dot matrix defining a given character is compacted into a sparse matrix, with the original character being reconstructed for printing or display from the compacted character defined in the sparse matrix. Each character in the complex character set is compacted and stored in memory one time only, with decompaction being performed each time a given character is to be generated. A set of symbols are defined to represent different patterns which occur frequently in the entire complex character set. Different combinations of the symbols define a given character. The information stored for each sparse matrix representing a given character is comprised of each symbol in the sparse matrix, its position, and its size parameter if the symbol represents a family of patterns which differ only in size.
