Input-output arrangement for working on a computer

Abstract

The invention relates to arrangements which can be used for inputting text symbols, data, signals and command sequences into a computer. An input-output arrangement for working on a computer comprises a housing (4) with symbol keys, and proximity sensors (1) for a left and a right joystick, as well as for selecting a row of keys, selecting a symbol in a selected row of keys, switching physical keyboard and mouse operating modes, switching a joystick operating mode, and confirming a selected command. Each proximity sensor is connected to its own variable frequency oscillator (2) and to its own reference oscillator (3) which proportionally increases the oscillation frequency according to the proximity of a person's hand to the proximity sensor. The arrangement further comprises: a master controller (5), a reference frequency oscillator (6), a frequency identification detector (7), a "keyboard" computer USB port (8), a "mouse" computer USB port (9), analog-to-digital output switches for controlling external execution devices (10), a selected program indicator (11), and a program unit (12) for illuminating a selected key and vocalizing the symbols on the selected key. The invention makes it possible to increase immunity to induced electromagnetic interference during data input / output.

Description

[0001] Input / output device for working on a computer

[0002] Description

[0003] The utility model operates as follows. Each contactless proximity sensor (CPS)1 responds to the approach of a hand and sends a signal to its own continuous-range generator (CRG)2, which proportionally increases the oscillation frequency depending on the proximity of the person's hand. The oscillation frequency of the CPS (CRG) is summed with the frequency of its own reference oscillator (F1 const)3.The sums of the frequency signals of the smooth range generators and the frequency signals of their own reference generators (Ргпд + F1 const) are fed to the control controller 5 in the software frequency extraction detector (Ргпд) 7 with the reference frequency generators (F2 const) 6, one for each frequency extraction detector (Ргпд) 7. The sum of the frequency signals from the smooth range generator, the own reference generator (Ргпд + F1 const) and the reference frequency generator (F2 const) 6 is fed to the software frequency extraction detector (Ргпд) 7, which extracts the difference of the sum of the frequency signals Ргпд + F1 const - F2const = Ргпд and feeds the extracted frequency signal (Ргпд) to the software address decoder in the frequency table. Frequency tables with a frequency grid are created separately for each decoder, there are fourteen tables in total. The frequencies of the reference generators (F1 const) 3 and the reference frequency generators (F2 const) 6 are identical, selected depending on the surrounding electromagnetic interference, and can start from 10 kHz and higher.The oscillation frequency of all smooth-range generators (SRG) 2, depending on the proximity of a person's hand to the contactless proximity sensors, ranges from zero Hz to 30 kHz and is programmatically divided into thirty equal parts. All fourteen SRGs 2 are programmed identically (up to 30 kHz) and operate identically. A specific hand distance to the contactless proximity sensors 1 corresponds to a grid section in the frequency table and corresponds to a specific symbol, keyboard row, and keyboard operating mode. Each of the contactless proximity sensors of the left and right joysticks is programmatically assigned to specific key symbols at will and depends on the switching of operating modes: push-button "keyboard," "joysticks," and joystick-controlled "mouse." Visual indication of the ordinal number of the software-controlled operation selection (joysticks, selected proximity sensors, push-button "keyboard," and "mouse") is displayed on indicator 11.The control controller sends signals to the computer USB port "keyboard" 8, sends signals to the computer USB port "mouse" 9, analog - digital output keys for controlling external actuators 10. The software block 12 turns on automatic illumination of the selected key and pronunciation of the symbols of the selected key. Input / output device for working on a computer
