Abstract

The invention relates to computing and can be used to organize manual entry of information into computing and control systems. The purpose of the invention is to increase the reliability of the device. The device contains the first 1 and second 2 blocks of switching elements, two triggers 4, 3, counter 5, element OR 6, decoder 7, delay element 8, register 9, indicators 11, RAM block 13, switch 12. The switching block elements enter the touch pad 16, the integrating circuit 15 and the adder 14 modulo two. Counter 5 and decoder 7 organize the scanning of indicators 11 and polling the sensor pads 16 of blocks 1, 2. When the operator touches the touch pad 16, the corresponding interrogation pulse undergoes a phase shift on the integrating circuit 15, resulting in two parity at the inputs of modulator 14 two, at the output which appears informational impulse. By this pulse, the binary code of counter 5 and the position code of block 1 or 2, in which the sensor 16 is touched, are entered into the output register 9. Blocks 1 and 2 are interrogated and information is displayed independently. 1 h. item f-ly, 2 ill. (Oh (L

When the volume of the block of switching elements is up to 16 sites in the register 9, the codes KOI-7 of the sites of block 1 corresponding to the digits O-9 and some punctuation marks, and block 2 corresponding to the letters from A to P (lat.) Are formed, and the device does not need the presence of the encoder. After reading the information from register 9, it removes the invention. It relates to computing technology and can be used to organize manual entry of information into computing and control systems.

The purpose of the invention is to increase the reliability of the device.

The device works as follows.

Blocks 1 and 2 are designed for the space-time coding of the fact of touching one of the touch pads 16. The timing diagram is shown

at the inputs of block 13 and the address of familiarity of this symbol on the first group of inputs of switch 12 and generates a write pulse that controls switch 12 on one side so that it connects the address set by the controller to the address inputs of the operational memory block 13 and writes a new character into the cell of block 13 addressed to them, which is equivalent to without touching the pad 16 (left) to replace the content of the familiarity of the block and when touched (right). At the mapping inputs

blocks 1 and 2 continuously receives a series of pulses. If there is no touch to the sensor and the front of adjacent pulses, there can be a pad 16 at the outputs of blocks 1 and 2 within the delay time of element 8, at the beginning and end of adjacent pulses, usually adjacent interrogation pulses during interrogation pulses (FIG. 2 a, b, and c) do not appear to overlap due to short pulses due to scatter of resistor ratings of no more than 0.5 MCS without any selection of ratings (Fig. 2e). Synchronously with the polling pulses, the code that arrives at the end is not violated, and at its output 40 histor 9 (Fig. 2h), and no pulses are scanned at the start and window of familiarity of the display unit 10 and trigger gates 3 and 4 are generated (Fig 2d). Since the gate time is shifted relative to the edges of the polling pulses,

the capacitor plate connected to the triggers 3 and 4 keep the zero state by means of the slider 16 through the capacitor of the operator's body, and writing and writing to the register 9 is impossible, connected to the common wire. This image — When the touch pad 16 is touched, is routed in FIG. 2 on the right. Inclusion of an in-band operator at the corresponding input of the tagging chain is equivalent to the phase adder 14 of blocks 1 and 2; the interrogation pulse is shifted away from the interrogation phase displacement to the side

stagnation, which leads to violation of the delay time due to an increase in the constant rhythm at the beginning and end of the time of the integrating chain 15 for the corresponding impulse of the request for the time determined by the corresponding input of the adder 14. This is called the parameters of the integrating circuit, which a significant increase in duration is 5–15 µs, depending on the impulses (Fig. 2), due to the imbalance of parisation of blocks 1 and 2. theta levels at the inputs of the adder 14.

Register 9 remembers the sensor 55 code. In this case, the cutoff of the first displaced pulse, the code and the switching unit code arrives at the information input of the elements on the front of the recording pulse, and the trigger 3 or 4 is later than the next trigger. . In the trigger, the fixer 7. In FIG. Figure 2 on the left for simplicity depicts the case of non-overlapping polling pulses. In the absence of touch parity on the inputs of the adder 14

Chany action pulses survey. Touching pad 16 is tantamount to including integrating chain 15, since

, and saves it to read, the obstacle of the new record. When the volume of the block of switching elements is up to 16 sites in the register 9, the codes KOI-7 of the sites of block 1 corresponding to the digits O-9 and some punctuation marks, and block 2 corresponding to the letters from A to P (lat.) Are formed, and the device does not need the presence of the encoder. After reading the information from register 9, he removes the service request and responds to the next entry.

The write pulse is stored at the input of register record 9 for two polling cycles. At the end of the recording, register 9 exposes
