SU1463309A1 - Light-sound device for psychophysiological relaxation - Google Patents

Abstract

The invention relates to engineering psychology and medical technology and can be used to maintain and restore the operability of special equipment operators and other equipment. The purpose of the invention is to accelerate the recovery of the psycho-physiological tone of a human operator. This goal is achieved as a result of the fact that the light pulse former is made with an optical shutter of variable transparency, and the rhythm-stimulation sensor is implemented as a functional converter. 2 Il.

Description

I

The invention relates to medicine and engineering psychology and can be used to relieve psychophysiological stress in stressful situations: professional psychophysical fatigue, appropriate superficialis and autotracelation.

The purpose of the invention is to accelerate the recovery of the psychophysical tone of a person .:

Figure 1 shows the functional diagram of the device; figure 2 - shaper light pulses with optical shutter variable transparency.

The device (Fig. 1) contains a control unit with a time relay 2 and a rhythm 3 sensor, a 4 light pulse generator, a light rhythm stimulator (screen) 5, a 6 transducer, a sound generator 7, a Bi electroacoustic transducer

The control unit 1 serves to turn on the supply voltage to the main units of the device and prepare it for operation. The time relay 2 is used to set the duration of the relaxation session, and the rhythm response sensor 3 is used to set the law of change in the frequency of the light-sound signals during the session.

Shaper 4 light pulses are made in the form of a mechanical light modulator 9 (Fig. 2) with a light source located inside a cylindrical drum and an optical shutter with two diamond-shaped cuts 10 and I, whose transverse diagonals AB and A B are divided by longitudinal diagonals CD and CD in the ratio of 1: 2. At the same time, the shortened CAD and C A D sectors of paragraphs 11, 10 correspond to inspiration, and the extended sectors of CBD and C to D correspond to breath, ensuring the duration

Screen 5 serves to visually reproduce light images. The phototransducer 6 serves to convert the light pulses of the imaging unit 4 into synchronization signals and modulation of sound, amplitude signals. Since at a constant p-Bones of the light source, the total light of the 1st flux is determined by the transparency area of a part of the optical shutter;) and the modulator, photoelectric multipliers, photodiode or (transistor arrays, output; approx. proportional to the area (of the incident luminous flux, Sound generator 7 serves for |; creating acoustic signals white: noise, synchronized and modulated) by signals of light ibrazhe-; shy.

Using the control unit 1, the power supply voltage is turned on, the duration of the session and the initial frequency of the effect, corresponding to () the patient's actual respiratory rate and the excited or normal state, as well as the set voltage from the slider 2 relay. .minimal rhythm frequency corresponding to the patient's breathing tjgcTOTe in a relaxed (sleeping) state. After that, the device is switched to automatic operation. In this case, the time relay engine 2 sets the speed of rotation of the rhythm sensor 3,

In terms of frequency, appearance, size and configuration, light images, in tune with the dynamics of which the patient breathes. At the same time, the created increase in the size of the light spot corresponds to the inhalation, and the decrease to the breath with a ratio of 1: 2. At the same time, the light flux enters the photoconverter 6, which controls the operation of the sound generator 7. As a result, a sound effect occurs in the head phones similar to the noise of the surf, the amplitude and frequency of which repeats the dynamics of changes in light signals.

The principle of operation of the proposed device, in contrast to the known ones, provides physiologically correct breathing and a smooth restoration of the patient’s respiratory rate from slow to normal, the effectiveness of the psychophysical effect,
