The device works as follows.

After the inclusion of the corresponding symbol at the input of the device from the drive, the text is output in the standard binary code corresponding to the Latin one. alphabet signs. After power on and operator training

Ί 1177842 8

(tactile glove settings) start the device. At the request of node 3 from an external device (a cassette recorder with a random access memory), periodically 5 are issued in the binary code LTC.

Separation of Russian and LTS is carried out automatically. LTS in the high order in accordance with the binary standard code has a logical 10 "0", so the output of the inverter 10 of block 29 is a single level, i.e. potential high level signal corresponding to "1".

In this case, in the device (FIG. 1) 15

A single signal level at the output of the inverter 10 opens electronic keys 12 and 13. The first one (key 12) connects the common bus 25 of the LEDs 23 to the bus 27, providing the backlight of the corresponding circuit 46 and 47 (FIG. 3) of the LTC, and the key 13 provides the connection of the electrical circuit between the output of the node 3 (FIG. 1) and the signal input of the block 26 25 of the generalized signal "Latin character". At the time of presentation of the LTS / burst, formed in node 3, it enters from the corresponding output of block 6 to the excitation winding of the 14 1 st EV 17 of the left 15 or right 16 group. At the same time on the windings' EV block 26 followed by pulses of the generalized signal "Latin character", which in intensity may be inferior to the main. After the transfer of the text LTS follows their Russian translation.

In this case, the bus 7 will be a single level, and at the output of the inverter - zero. The keys 12 and 13 will be closed by a low signal at the control input, and the key 11 will open and connect the common bus 24 LEDs (LEDs) 22 to the bus 27. Consequently, at the moment of presentation of the Russians hell of the vehicle, the corresponding LEDs 22 (FIG. 1) are excited, providing Illumination of letters of the Russian alphabet, for example, 43 and 45 (fig.Z).

The operation of the device according to FIG. 2 is different in this mode in that, using block 29, the separation of LTS and digital vehicles is additionally performed.

This is done in the following 55 sequence. Digital TS, as well as LTS have in the senior discharge "0", therefore in addition from an exit

The ίth element AND 30 and 31 of the unit-level signals are grouped using the first element OR 36 of the separation unit 29. The unit level signal from the output of the element OR 36 through the elements OR 37 and 38 and the inverter 10 opens the key 12, which connects the bus 25 to the common power bus 27, and using the key 13 closes the output of the node 3.

Consequently, when perceiving a digital vehicle, block 26 is inactive, which allows the operator to more clearly distinguish digital vehicles that are accompanied by the backlight of the <th SD 28. Such an indication allows the operator to speed up the generation of reflexes to digital vehicles when sensors 34 and 35 are working and to record more clearly LTS.

When comparing the options of the device, it should be noted that the first is simpler, since it does not contain the LTS separation unit and digital vehicles, the presentation of which is accompanied by a generic signal "Latin character", because the upper digits of these characters have a logical "0".

On the other hand, the perception of a Russian text vehicle increases the accuracy of recognition of digital vehicles, the difference of which is that the perception of LTS is carried out using sensors of various levels and additionally using sensors of a generalized signal "Latin character", and digital vehicles are perceived as separate sensors.

The advantage of the device ^ shown in figure 2 _; is to improve the accuracy of perception of LTS, as it provides a clearer gradation of signs of the vehicle (tactile and visual). Stimulation of digital vehicles in this embodiment is no longer accompanied by the parallel operation of the “Latin character” generalized signal sensors.

Consequently, the device presented in figure 1, it is more expedient to use in universal systems of tactile perception of information, where LTs are quite rare. The device presented in figure 2 ^ is better or preferable to use in specialized and training systems and machines, where there is an increased requirement for perceptual accuracy · LTs.

The operation of the TC display cell has already been considered when describing the operation of the device. It should be added that in FIG. 3 for simplicity, the LEDs 22 are not shown, which provide illumination of the image of the letters 43 and 44 of the Russian alphabet. On fig.Z shows only one of them - the letter "C". The difference is that in LEDs 23, the slit is located above the opaque mask 49, and in LEDs 22, the screen 50 has slots around the perimeter below the plane of the mask 49 and the light from them is reflected from the screen 41, giving a uniform light image of the outline of the Russian letter. Also, the LED 28 lights up the mask 48 with the image of a digit (FIG. 3). When assembling cell 42, an external transparent screen 51 is first installed, which is sealed around the perimeter with glue and sealed with a gasket 52 located between screen 49 and a flange 53 made around the perimeter of the pro-25 transparent screen 51.

Outlines 46 and 47 with the image of '(three-dimensional) Latin letters using

The adhesives are fixed on the opaque mask 49. The screens 50 of the LEDs 22, 23 'and 28 are fixed on the reflective screen 41, which is simultaneously the cover of the cell 42 and is attached to it with screws.

Between the screen 41 and the mask 48, a gasket 54 is installed around the perimeter of the cell 42, through which, in front of the screen, a force is applied to the screen 49 when assembled at the cover 41. The screens 50 are attached to the screen 41 by flanges.

To the gasket 54, in the middle part, additional edges (not 15 shown) are attached, which divide the light reflecting part of the screen 41 into sections corresponding to the letters of the Russian alphabet and numeral. The ribs can also be performed on the screen 41. The rib 20 separates the sections of the letters 43 and 44. The wiring to the LEDs is placed around the perimeter of the cell between the screens 41 and 49. The conductors are withdrawn from the side of the cell body 42,

The use of the invention improves the perception of tactile influences.
