System for the composition of symbols

The invention relates to the symbol composition by means of an optically electronic device that uses a process to display all symbols simultaneously and in accordance with a predetermined program and with the symbol order scans to cause a computer to arrange the symbols as desired to provide the required composition of symbols.

The development and widespread use of digital computers has advanced the development of terminal display devices that provide the operator with the output data of the computer. The data usually consists of alphanumeric, data, although the special symbols that with computer generated maps, electronic drawings, airplane plans, automobile design, graphic works of art require large increases in symbol capacity.

The oldest method uses the Formation of Lissajous figures produced by a repetitive electronic generator. The arrangement of the symbol

\ T 3 0 9844/05 7 5

on the display device is essentially independent of the symbol generator. The disadvantage of this procedure is in that each symbol requires an independent electronic generator, and that the generation time for each Symbol can be different, and that changing a set of symbols changes the associated symbol generator circuitry makes necessary.

A second symbol generation method is similar to the Lissajou method, but depends on the selection of stored punch commands in such a time sequence that a symbol is produced. This approach is quite flexible and gives a symbol of excellent graphic quality. the Strike method is particularly suitable for symbols that are composed of straight sections. However surrendered curved lines introduce significant complexities in both addressing equipment and generator timing. This approach therefore requires extensive buffering and refresh storage and is primarily for presentations suitable that require a limited number of symbols, 300 - 500 symbols / sec.

Another way of generating symbols uses electronic function generators in conjunction with the horizontal ones and vertical deflection signals are used to apply an off-on intensity modulation signal to raster scan video produce. The disadvantage of the symbols generated in this way is that they depend on the raster scanning properties of the Representation are dependent. Each character requires the production of a complex electronic function generator and requires a new design for a new icon. Symbols that are written in the circular or Diagonal elements used are quite difficult to instrument. The number of symbols available is

309844/0575

literally depending on the number of provided Function Generators. The accuracy of the symbol arrangement is not high because the limit is reached as a function of sweep linearity, raster stability, and timing accuracy. This is a generally flexible one but laborious procedure. ,

Another method of syrabolic production uses a direct one electronic analog of the symbol, whereby a character is selected and read out directly. These systems deliver about 5000 - 10 000 characters / sec. However, the symbols are difficult to change as new characters are constantly needed. As a general rule it can be said that each Symbol is generated in a serial manner as opposed to being generated simultaneously.

A number of patents have been published in this area but they have a disadvantage in one area or another, insofar as the composition of the speed is affected.

U.S. Patent 3,324,346 describes a character generation system which that despite the use of a cathode ray tube scanner for a font of characters only part of the Instead of scanning the entire document, with the result that not all characters are scanned at the same time be made available for quick electronic selection and assembly.

U.S. Patent 3,226,706 describes a cathode ray tube actuator and printer controlled by a coded mask and connected to a flying dot scanner used with a mask on which the characters in

309844/0575

digital format instead of using a transparency of the actual characters. Widely suffers this patent has the disadvantage that not all characters are available for selection at the same time.

U.S. Patent 2,984,750 describes a modified optical System for off-axis flying point scanners, which has a cathode-ray scanner, but mask diaphragms used to maintain equal light intensity during a sampling period. This invention is directed principally on the maintenance of the color balance and is not directed towards the simultaneous sharing a variety of characters for automatic selection and their composition.

U.S. Patent 2,907,018 shows a character generator system for the production of selective indices using three cathode ray tubes. Two of the cathode ray tubes are used to provide the horizontal and vertical scanning of two matrices and a third cathode ray tube is used to represent the character generator. The basic principle used in this patent is the generation of Lissajour figures as described above, rather than generating a raster scan.

U.S. Patent 2,754,360, which has a character synthesizer describes uses a floating point scanner, but the system only generates one character at the time of a lens and therefore does not provide a multitude of characters at the same time for quick selection and composition .

The invention to be described here is unique in the sense that all desired symbols are electronic at all times are available. All symbols are generated at the same time and

309844/0575

symbol selection is very easy. A cathode ray tube system with deflection, brightness control and synchronization electronics creates a constant grid pattern. Pas selected Halftone pattern contains a number of lines that are consistent with the desired symbol quality (usually about 24 lines). This pattern is one of each element Considered matrix lens arrangement, each element being the Matrix corresponds to one symbol of a matrix of symbols, referred to herein as a font matrix.

The light beams emitted by the scanning electron beam are imaged on the symbol mask by a lens matrix. Where the mask is transparent, the rays of light excite photosensitive ones Elements behind the mask. This electronics symbol then provides a video line that corresponds to the scan line, as modulated by the clear sections of the symbol will. The selection of the symbol to be displayed then simply consists of closing an electronic switch, whereby only the scanned symbol selected by a particular photosensitive element is passed through.

Synchronizing line deflection signals are obtained by operating the scanning cathode-ray tube and the composite cathode-ray tube with a scan-synchronizing deflection generator. The symbol is automatically placed in its proper place on the face of the composite cathode ray tubes by coordinates generated from the data stored and manipulated by the computer programs used. The input format program supplies the symbol selection signal and the symbol arrangement information. The Syiabol arrangement information is fed to the assembly cathode ray tubes. * Via a computer system.

All symbols of a font matrix are generated simultaneously and the character matrices can easily be exchanged in the system as desired. In addition to the increased number of symbols that are supplied in a font matrix _t and in addition to the different symbols that are required and whose use is made possible according to the invention, there is also an advantage that the output sampling rate of the symbols is that of the Digital Computers reaches and exceeds so that undue computer latency is avoided and so that the symbols are available for computer processing when a time-sharing computer system is used.

In illustrating the merits of this invention in the prior art, the system of the present invention can be briefly referred to as a symbol assembly system having a group of sub-systems composed of a first device for simultaneously scanning a plurality of the symbols, by second means responsive to the first means to simultaneously scan all symbols and sense the scanned symbols, and third means including computer programmed equipment, computer programs and including a digital computer in communication with the second means for automatic selection of the symbols in a predetermined To create order, and to arrange these symbols in predetermined positions, thereby enabling a preselected composition of the symbols.

The facility can also have a fifth facility as one Input for the third device included to enable manual input of the symbols in a predetermined arrangement, the third means providing the digits of the symbols input by the fifth means to also to enable the preselected composition of the symbols.

The symbol composition system can be operational can be composed of the following steps:

The number of symbols that can be presented for selection at the same time is a function of the system component that is activated on slowest works. Typical operating cycles of the critical System component and other related parameters are given in Table 1 below:.

The afterglow time is defined as the time it takes for the fluorescent screen brightness to fall to 30% of the original brightness, since each resolution element must be sufficiently distant in time that the fluorescent screen excitation from the previous track has decayed to a value that would allow the photodetector no longer energized by the time the scanning beam passes through the next aperture. A conservative estimate shows that this fall time is in the range of 0.1 10 "seconds when video threshold limiting is used.

The time to scan a frame or a symbol and, according to the invention, all symbols in the font matrix, da all such symbols are mapped and scanned at the same time is given by the following equation:

T _f ^ (T _r ) (N _r ) (N ₁ ) + (T _v )

where T- = symbol sampling time in seconds / symbol

As a result, the number of symbols per second for a system with the typical values mentioned is:

The scan cathode ray tube does not need in any way to be accurate as it is only used as a time-scanning exposure device. The placement accuracy of the symbol is then a function of the placement accuracy of the display cathode ray tube system. «■

An inexpensive electro-optic system that uses a cathode ray tube exposure system used, creates all symbols, at the same time. All symbols intended for display are uniquely selected and based on a digital process a distant cathode ray tube displayed much faster, than is possible with any existing symbol generators. .

Furthermore, the generator system can create so many different

30 9 844/0 575

separate display units operate as desired, each with a separate format. The number of to use Symbols can easily be changed, and the introduction of special typesetting matrices that are specific to a particular user are unique is possible. In this system there is no limit to the symbol configurations that can be used. The quality of the reproduced symbols is essentially determined by the choice of the user, since the larger the number of Scanning lines per Syiabol a greater quality of the composition on the cathode ray tube, although this comes at the cost of reducing the symbol rate.

an opaque background 43, and the background of the corresponding symbols is also opaque so that
Light only passes through the appropriate symbols. Of the
Sensing matrix background 53 can be either clear or
be opaque. Since their sensors are generally made of photosensitive material, such as cadmium sulfide or
like that, it does not really matter whether the background 53 is transparent or opaque.

It is noted that although only four symbols are shown for ease of illustration, a font matrix is made up
Symbols and the corresponding lenses and sensor devices can handle up to several hundred symbols.

To explain the method used, refer to the figures
5, 6, 7, 8 and 9, the method having the unique ability to identify all symbols of the font matrix
at the same time.

A single deflection or line is made from the moving beam of the flight point scanning cathode ray tube 32. This deflection begins at point A, the point moves to point B horizontally across the face of tube 32 in one
Direction indicated by the arrow (AB). The return trace of the deflection line or the return suppression is known and will not be discussed here.

Light from the point at point A is seen by the typesetting matrix subsystem 40, specifically, all lens elements, shown here as lens elements 32a and 32b, all
Symbols of the typesetting matrix, which are shown here as symbols 42a and
42b, and all of the individual photodetector sensors, referred to herein as sensors 52a and 52b, to the

3098 * 4/0575

the above mentioned lens elements, symbols and sensors. to the movement due to the simultaneous display of the moving beam through all lens elements .. As a result, the lens element 32a, the symbol 42a and the sensor 5.2a will react to the beam movement (AB) and one thereby delivering light movement represented and moving from point A ¹ to point B ¹ in a direction denoted by (A'-B ¹ ). Similarly, lens element 32b, symbol 42b and sensor 52b respond to beam movement (AB) to provide a movement of light represented thereby and to move from point A "to point B" in a direction derived from (A "B _-."). is designated.

In Figure 6, a single line deflection leads through the beam movement (AB) to the deflection (A'-B ') via the symbol 42a between A ^ ¹ and B ,, ¹ , and the deflection (A "-B") via the symbol 42b between A ^. "and B ^". .

Although only one deflection of the cathode ray tubes (A-B) is shown For a further explanation, deflections at three different horizontal positions of the cathoderi-beam scanner are used 32 discussed. * ■ ---- "'"' \

Therefore, the effect of the deflection ""'(Ä-B) results in a deflection at the top of the symbol "" around "" deflections from "' * '" A ^ ¹ to B /' · and from A ^. " after "B ^"'results in "to". "

Similarly, if a deflection of the tube 32 occurs at its center, the symbol ^ would appear between the points Ap ¹ and. Bp ¹ and the symbol "42b between points' A ₉ " and B ₀ "scanned - .- ^., - ■ - , ■ - - ■ -

Also, when a Abtastiiüg ^J of the tube .32. occurs at the lower part of the " tube", the ^ yriiböl 42a between the 'points A, ^1. and B, ¹ and the symbol' 42b * between 'deri.'Pünkteii Ä, ^lf: ünoi B ^'"would be scanned .

30984A / 0575

As a result, when the scanning occurs over the symbols 42a and 42b at their uppermost position, the becomes more transparent Parts of the symbol represented and sensed as pulses falling light, the width of which is proportional to the time during which which passes the scanning with light. Therefore, in FIG. 1, the width of the pulses output from the sensor 52a is narrower as the width of the pulses output from the sensor 52b due to the sampling time.

Similarly, if in Fig. 8 a scan over the central part of the symbol 42a is running, two transparent parts are scanned thereon and, as a result, the sensor 52a two pulses are emitted as a result of the scan occurring at the center of the scanning tube 32. In the same way there will be a single pulse from sensor 52b as a result of the passing deflection.

When the scanning tube runs over the lowest part, the show Pulse outputs of FIG. 9 that a single pulse is output by sensors 52a and 52b. In all cases, the Scanning direction or the time orientation of the sensor output pulses 7, 8 and 9 read from right to left.

It is therefore apparent that not only is a symbol scanned when the cathode ray tube is scanned, but rather that all of the symbols that make up the typesetting matrix are scanned at the same time, thereby enabling the computer to under command any desired symbols in a predetermined order and controlled by those in the computer program select existing data.

The following describes the computer programming of the system. ' Referring to FIGS. 1 and 10, the computer routine 12 for channel 1 is shown in Table 2, while the Computer routine 22 for Channel 2 is given in Table 3 below.

309844/0575

The routine read instructions for channel 1 are provided by instruction 95, while the routine read instructions for channel 2, which are to be read into the computer, are supplied by the commands 94.

Stored data from channel 1 consists of the composition of the symbols to be supplied and the original symbol coordinates using "the relationship of a symbol with reference to a other as shown at 11 and the computer read instructions 97 provide the relevant commands for reading the information into the computer. Similarly, the data from channel 2, shown at 21, which consist of the set of symbols to be supplied and their original symbol coordinates, with the help of the relationship of a symbol with reference to another, and. Computer read instructions 96 provide the corresponding command to read the information into the computer.

Should you wish to manually enter data into the computer this is achieved by the manual data keyboard 17 for channel 1, and the command to accept such manual keyboard input data is given by instruction 99 * In the same way, the command for accepting manual keyboard data given by the routine instruction 98 from the keyboard 27 for channel 2.

All input instructions, computer routines, stored data and such other data or instructions as processed by the computer for both channel 1 and channel 2, are given by executing instruction 100, with data from auxiliary storage sources or from manual or other Inputs are transferred to the central core memory of the computer system used.

Computer instructions 101 and 102 are used for channels 1 and

3098ΛΑ / 0575

2 marked to the right and left margins of the merged
to fix strips to be crushed. The length of the line should be in cm

to enable the execution of these instructions. This activity is known as justifying right-wingers and left margins. It should be understood that the instruction may be different from instruction 102 because it is different Line width may be desired. There is a different composition of words in channel 1 compared to channel 2 may be necessary, the resulting compositions can be different, or if a plurality of the same compositions are to be made at the same time, the Instructions for channels 1 and 2 must be the same.

Instructions 103 and 104 are created for channels 1 and 2, respectively, to compute a line of words, as well as the X-Y coordinates for each symbol in these words. In so far as earlier instructions for channels 1 and 2 may be the same or different as far as the length of the line is concerned the lines of words for channel 1 may be the same or different from the line of words for channel 2.

Correspondingly, instructions 105 and 106 are for channels 1 and 2 created in order to ask the computer whether the data words for one line of the respective channel are sufficient to make up a full line. If the computer determines that there are insufficient words to fill a line, it will they request that more words be read into the line by adding instructions 127 for channel 1 and instructions 128 for Channel 2 are executed. As a result of executing these instructions, instruction 103 becomes channel 1 and 104 becomes Channel 2 repeated. These instructions are followed by a question from the computer using instruction 105 and / or 106 for channels 1 and / or 2, as may be the case. If, as a result of the execution of instructions 105 or 106, the interrogation yields a yes answer, namely that it

309844/0575

there are enough words to deliver a full .. line, instructions 107 and 108 for channels 1 and carried out. Instructions 107 and 108 provide corresponding ones Adjustment of the distance between the words of channels 1 and 2, in order to form the right and left border.

Next, the computer is queried by instructions 109 and 110 for channels 1 and 2, respectively. You will be asked whether the the line just composed is justified. If the answer is no, the computer is instructed to go back and instructions 107 and 108 for channels 1 and 2 to run again. If the answer is a YES, instructions 111 for channel 1 and 112 for channel 2 are executed. Instructions 111 and 112 ask the computer for the X-Y coordinates recalculate each symbol from its original entry position in each of the two Channels has been moved.
