Description

The inventions relate to the field of medicine, namely to means of psychological and emotional relaxation of people and to protect the eyes of a person at his request from unwanted light exposure and a visual demonstration of unwillingness to come into contact with other people, and can be used on long trips by public transport, places rest of a large number of people, in public institutions where the regime of the day is observed with allocated rest time, etc.

A device for causing a state of sleep, namely a bandage for sleeping in the form of glasses, containing a coating for the eyes and forehead and equipped with magnetic field sources in the form of permanent magnets [Description of the utility model to the certificate of the Russian Federation No. 11711 of 05.25.1999, IPC ⁶ A61M 21 / 02, publ. November 16, 1999].

The disadvantage of this device is that for a visual assessment of the situation before bedtime and after sleep, you have to remove and put on a bandage the required number of times, which does not contribute to the declared relaxation of the user, but more annoys him.

A device for protecting the eyes from the action of bright light, namely, from intense blinding light radiation during welding, containing a half-wave liquid crystal matrix, two polarizers, one of which is located with the possibility of focusing using a lens of polarized light on the specified matrix, and the other is located the ability to absorb or transmit light transmitted through the cells of the specified matrix, and a control device comprising a matrix of photosensitive elements, providing vayuschih supply signal from the photosensitive element in contact with their light on the corresponding half-wave of the liquid crystal cell matrix [Disclosure of the invention to RF patent №2154851 of 19.10.1998, MPK ⁷ G02C 7/10, B60R 1/00, B60J 3/00, publ. 08/20/2000].

The principle of operation of this device is that when a flash of bright light appears, the liquid crystal matrix becomes opaque in the zone of the most intense glow and opaque or transparent in the zones of less intense glow. In practice, this is possible only in the case of a figured - spatially curved - matrix design. At the same time, there is no way to disable the implemented functions in the event that the intensity of the glow still allows you to keep your eyes open. In addition, the use of such a complex and bulky device to protect the eyes during sleep is impractical.

Known glasses with adjustable transparency, containing lenses, each of which consists of two substrates, upper and lower, with conductive layers on their facing each other, between which there is a layer of liquid crystal, a photodetector, a voltage control circuit, two inputs of which are connected to the outputs of the photodetector, and two outputs with conductive layers of the lenses, a voltage source whose terminals are connected to the buses of the voltage control circuit, which allows the user to adapt the transparency of the lenses to change, even when expected ambient light condition [Disclosure of the invention to RF patent №2063061 from 23.03.1987, IPC ⁶ G02F 1/13, publ. 06/27/1996].

The use of such chameleon-type glasses to protect the eyes from external light influences during sleep is impractical and economically unjustified. In addition, glass shading does not allow outsiders, for example, a stewardess in the cabin of a passenger aircraft, to find out if a user is sleeping or not and is available for communication - i.e. whether the passenger’s eyes are open or not.

Known glass filter for welding, which is able to quickly switch between a state of high degree of light absorption and a state of low degree of light absorption and, conversely, in accordance with changes in the intensity of light emitted during welding, containing two liquid-crystal nematic type cells located between transparent, with deposited on them with electrodes plates that can be connected to a voltage source and which are equipped with coatings that determine the orientation of the molecules, and which They determine the direction of orientation of the molecules with a relative angular arrangement with respect to their bounding surfaces, thereby causing an optical rotation in the liquid crystal medium in the absence of voltage between the electrode coatings on the plates or when the voltage is applied [Description of the invention to the RF patent №2126548 of 04.25.1995, IPC ⁶ G02F 1/1337, G02F 1/1347, A61F 9/06, F16P 1/06, publ. 02.20.1999].

The automatic inclusion of a high degree of light absorption during its flash, which is typical during the welding process, is unacceptable in a situation where it is necessary to sleep under conditions of moving or flying, when the lighting is almost stable in the position of sufficient comfortable illumination of the passenger's location zone. In addition, in conditions when a person imitates a state of sleep, such a device cannot be applicable, since this will require complication of its design and a significant expansion of functionality. At the same time, outsiders will not be able to determine the physiological state of this person and, accordingly, his accessibility for communication, for example, with the aim of offering drinks or food.

The problem solved by the inventions and the achieved technical result consists in creating a simple way of protecting one’s own organs of vision from external light influences during sleep or its imitation, controlled by a person or authorized outsiders, and creating a device for its implementation, which will allow for successful psychological and emotional unloading users of different ages.

To solve the problem and achieve the claimed technical result, in the method of protecting the human eye from external light influences during sleep or its imitation, with an arbitrary closure of the eyelid during sleep or consciously to simulate between the eye and the light source, a protective opaque screen is formed, and when opening the eyelid arbitrarily or deliberately protective light-opaque screen is changed to a more transparent one.

Besides:

- a protective opaque screen is formed when the eyelid is arbitrarily closed during sleep or consciously to simulate it for at least 0.5 s, and removed while keeping the eye open for at least 0.5 s;

- to stop the sleep regimen or its imitation, the closed eye is exposed to artificial light radiation;

- to stop the sleep regimen or its imitation on a person exposed to artificial vibration, mainly in the head area;

- to stop the sleep regimen or its imitation, a person is affected by a sound stimulus;

- to stop the sleep regimen or its imitation, a person is affected by low-current electrical signals;

- to stop the sleep mode or its imitation on the human body act tactilely.

To solve the problem and achieve the claimed technical result, the device for protecting the human eye from external light influences during sleep or its simulation includes a protective liquid crystal screen, configured to change the light transmission from light to dark depending on the position of the human eyelid, and is equipped with at least one non-contact opening / closing eye sensor.

Besides:

- the protective screen is made in the form of glasses worn on the nose or mask worn on the eye area;

- the protective screen is made in the form of a visor located between the head of a person from the side of his eyes and a light source;

- the device includes at least one LED awakening from sleep or its simulation, made with the possibility of exposure to the eye in the eyelid;

The invention is illustrated by figures of reproductions, where:

- in FIG. 1 shows a general view of a device for protecting a person’s eyes from external light influences during sleep or its imitation, made in the form of glasses with a transparent screen;

- in FIG. 2 shows the device of FIG. 1 with a darkened screen;

- in FIG. 3 shows a general view of a device for protecting human eyes made in the form of a visor with a transparent screen;

- in FIG. 4 shows the device of FIG. 3 with a darkened screen.

It should be noted that hereinafter, the position numbers are given rather conditionally, since there is a great variation in the performance of the elements making up the device, their miniaturization, and, accordingly, the possibility of variously placing sufficiently compact devices within the dimensions to protect the human eye from external light influences. For this reason, the figures of reproductions can be shown as extremely specific location of the elements of the device, and preferred, which does not limit the possibility of its implementation. Dotted extension lines indicate the locations of a possible or preferred arrangement of conventionally not shown device elements.

A device for protecting a person’s eyes from external light influences during sleep or its imitation includes a protective liquid crystal screen 1, configured to change light transmission from light to dark depending on the position of the human eyelid, and is equipped with at least one non-contact opening sensor 2 / closing of the eyes, while the protective screen 1 can be made in the form of glasses 3, worn on the nose or mask (not shown conventionally), worn on the eye area, or in the form of a visor 4 located between the head h man from the side of his eyes and a source of light.

Since the device for its main purpose is intended for a more comfortable sleep, it provides the opportunity to independently interrupt the state of sleep or its simulation by simple programming or with the help of strangers. For this, a device for protecting the human eye may include: one or more LEDs 5 awakening from sleep or its imitation, made with the possibility of exposure to the eye in the eyelid; one or more module 6 of the vibration signal of awakening from sleep or its simulation, made with the possibility of exposure, mainly in the region of the head; one or more sound source 7 located in the region of the human ear; one or more sources of low-current electrical signals 8 with electrical contacts for interaction with open areas of the human body; and / or one or more sources of tactile effect 9 on a person. The above elements (or stand-alone devices in the device for protecting human eyes) are included, for example, from the radio module 10 or infrared receiver, etc., built into the device for protecting the eyes, and reacting to the corresponding third-party signal.

Thus, the method of protecting a person’s eyes from external light influences during sleep or its imitation is characterized by the fact that when the eyelid is arbitrarily closed during sleep or consciously to imitate it between the eye and the light source, a protective opaque screen 1 is formed, and when opening the eyelid, also arbitrarily or deliberately, the protective opaque screen 1 is changed to a more transparent one. A protective opaque screen 1 is formed when the eyelid is arbitrarily closed during sleep or consciously to simulate it for at least 0.5 s, and removed while maintaining the eye open for at least 0.5 s.

In addition, to stop the sleep mode or simulate it, the closed eye is affected by: artificial light radiation, for example, LED 5; artificial vibration, mainly in the region of the head, for example, by module 6 of the vibration signal of awakening; a sound stimulus, for example, a source of a sound signal of the 7th type of an acoustic speaker, a bell, a buzzer, etc., located in the region of the human ear; low-current electrical signals with a special source 8 with electrical contacts (not shown conditionally) for interaction with open parts of the body; and / or tactile, for example, with a hammer-type source, chair 11, etc. In all cases, a signal from a third-party device activates the mode of awakening from sleep or interrupting a state that imitates a dream.

Let us analyze the essential features of inventions.

A way to protect the human eye from external light influences during sleep or its imitation is that when the eyelid is arbitrarily closed during sleep (or consciously to simulate it), a protective opaque screen is formed between the eye and the light source 1. If we take into account that At first, there was no screen at all between the eye and the light source, or there was a certain screen 1 in the form of transparent or darkened lenses, for example, glasses 3, then when the eyelids are closed, a protective screen 1 appears. In this case, a kind of flat or figured glass or visor 4 can act as a protective shield 1, which have the ability to change their light transmission from insignificant to maximum impermeable to light waves. Those. Although the protective screen 1 has a darker, but still translucent design, under certain conditions it either becomes dark, significantly weakening the power of the light flux up to 1000 times, or becomes lighter, actually ensuring its transparency to the level of transparency of two polarizing films on glasses. In the case of the present inventions, the conditions for changing the light transmittance of the screen 1 were used to select the moment of closing or opening the eyelid of the eye, and not instantaneous, but with a delay of at least 0.5 s. It has been experimentally established that the present time is enough to calmly arbitrarily or consciously “turn on” or “turn off” the visually perceived effect of the beginning of falling asleep or switching to wakefulness mode, as well as to change the consciously made decision to the opposite without misleading others. If the selected time is less than 0.5 s, then screen 1 will be simply uncontrollable - it will quickly respond to almost any eyelid movement. If the selected time is greater than 0.5 s, then the excessive delay in switching from one mode to another will simply annoy the user, which will lead to the leveling of the inherent effect of psychological and emotional relaxation from the use of the claimed technology. If necessary, you can individually adjust the on / off time of the moment the light transmittance of the screen 1 changes for each user, however, in all cases, the delay should provide a comfortable mode for switching the light transmittance of the screen 1, ignoring the accidental opening / closing of the eyelids of the eye (blinking).

In practice, these functions can be easily implemented by using as its protective screen 1 its liquid crystal version. The liquid crystal screen 1 (and the visor 4) has the ability to change light transmission from light to dark depending on the voltage at its electrodes. The applied voltage builds up liquid crystal molecules in a certain way, due to which the light transmittance of screen 1 changes from transparent - in the absence of voltage to dark - when a corresponding voltage is applied (a popular article on masks based on liquid crystal screens, see http://www.rsco.ru /product/Balder.pdf, the largest manufacturer of LCD screens - http://www.winstar.com.tw/main.php). The voltage on the liquid crystal screen 1 is supplied through a control chip (microprocessor) 12 from a non-contact sensor 2 opening / closing the eyes, which responds to the position of the eyelid relative to the eyeball.

The compact protective liquid crystal screen 1 is successfully integrated into the frame of glasses 3, worn on the nose, as well as in a mask worn on the eye area. In addition, a protective screen can be built into the back of the seat 11, including the seat of a passenger plane, train, etc., for which it can be shaped like a reclining visor 4, installed at the right time between the person’s head from the side of his eyes and the light source .

Also, the method provides for the possibility of a special termination of the sleep mode or its simulation, which the user selects either on his own, or this mode is initiated by someone from outside, for example, a flight attendant in an airplane. The need to use these opportunities is due to the fact that sometimes it is necessary to wake a person in the most appropriate way for him. For example, to prepare for departure at the desired railway station, to take medicine, to eat on a long flight by plane, etc. Some of the most accessible and diverse ways of ending the sleep regimen or imitating it were chosen, in contrast to the “traditional” shaking of the shoulder or announcements with a loud voice, which also attract the attention of people around, which can cause a natural feeling of discomfort and awkwardness.

As a result, the user's closed eye can be exposed to artificial light. For this, an awakening LED 5 is used, located near the eyes with the possibility of a direct effect on them in the eyelid.

Also, a person can be affected by artificial vibration, mainly in the area of the head - at the location of the main actuator - points 3, masks, visor 4 chairs 11, etc. For this, module 6 of a vibration signal of the type of a microelectric motor with a shifted center of gravity is used - these are exactly the ones used in mobile phones.

A person can be affected by a sound stimulus, for which you can use the compact source of sound signal 7, located in the area of the user's ear. For this purpose, an acoustic speaker, a bell, a buzzer, etc., with the appropriate soundtrack - a human voice, a melodic ringing, a popular melody, etc. are suitable.

A person can be affected by low-current electrical signals interacting with exposed areas of the body. If it is 3 glasses or a mask, then on the head, if it is a passenger seat 11, a sofa and other furniture for sitting, then any other open areas - at the user's choice. To do this, you can use any safe source of low-current electrical signals 8 with the outputted electrical contacts.

A person can be affected by a source of tactile (mechanical) influence 9. This can best be implemented on large-sized devices such as chairs 11 or other furniture. As a result, the back vibration massage is turned on, the back of the chair 11 rises, a hammer falls on the shoulder, a mechanical wave of characteristic amplitude runs through the seat, etc.

For the purpose of accurate awakening, a person can be affected by other methods that can be implemented in the claimed devices, for example, in the form of a combination of the above and others.

All these devices are turned on forcibly after external exposure, for example, by a flight attendant, attending physician, parents, etc. or automatically, after appropriate adjustment of the control system.

The experience of using a number of the listed devices has shown that, in particular, children like to fall asleep during the day with a mask or in glasses 3 to protect their eyes. After such a dream, they wake up more collected, obedient and able to perceive more information and better remember it. Adult people, having tried to use this method of protecting the eyes from external light influences during sleep (as well as simulating it) and having tested the appropriate devices for its implementation, note a stable comfortable state, psychological and emotional relaxation.

The undoubted advantage of this method of protecting the eyes during sleep or its imitation is that it is not necessary to perform not only unnecessary physical actions, but also to be safe in controlling the motility of the organs of the body, for example, to correct a special fabric mask that has slipped or rickety as a result of involuntary rotation of the head, sometimes used for long flights by air, or any other items that people usually use to protect their eyes from bright light when resting and cover their eyes - towels, scarves, napkins, own hands, etc., as well as additionally manipulate hands, which is annoying, etc.

As can be seen from the description, the method of protecting the human eye from external light influences during sleep or its imitation can be implemented in fairly compact devices for individual use (glasses 3, masks), as well as, of course, on stationary public devices such as passenger seats 11. All automation of these devices can be powered by a compact power source such as lithium batteries CR2032. On stationary devices such as passenger seats 11, automation and all actuators can be connected to the vehicle’s electrical network.

The use of inventions is illustrated in the following examples.

Example 1

An individual device for protecting the human eye from external light influences during sleep or its imitation is made in the form of glasses 3 (see Figs. 1 and 2).

The wide rim 13 is equipped with liquid crystal glasses (protective shields 1), connected with their findings to a control system (not shown conventionally) based on a control chip 12 or a microprocessor. Two non-contact sensors 2 of opening / closing eyes, LEDs 5 of awakening from sleep or its imitation, duplicated by module 6 of the vibration signal of awakening, installed in the region of the temporal sections of the head, are built into the frame 13. All automation is powered by the aforementioned compact battery CR2032. The weight of such glasses 3 is approximately 80-120 g. Glasses 3 are fixed on the head by landing on the nose and with the help of an adjustable braid (or arms 14) above the ears.

Wearing glasses 3 does not interfere with the implementation of ordinary needs, such as reading books, watching TV, communicating with someone you talk to, etc. When the time comes for rest or sleep, without committing any additional actions, except for those previously performed, the user closes his eyes. The eye opening / closing sensors 2 provide a signal to the control unit (it is also a microprocessor or control chip 12), which generates a command to the liquid crystal screen 1 (or screens 1 according to the number of eyes) by applying voltage to the corresponding electrodes. The molecules of the crystals are rearranged, and the protective screen 1 becomes darkened so as to remove the discomfort from bright street light or artificial light in the room. The eyeglass control system 3 can be configured so that after an individually set period of time after dimming the screen 1, the wake-up LEDs 5 and / or the wake-up vibration module 6 are turned on.

People see that the glasses of glasses 3 are darkened, and this signals them a certain order of behavior in this situation, for example, it is necessary to ensure silence and not to disturb a person, while it is possible that you wake him up, for example, to take medicine, etc. Forced waking is performed, for example, as mentioned above, by applying a radio signal or an infrared signal to the receiving module 10 of the eye protection device, which initiates the waking mode.

If the user, after the activation of the wake-up LEDs 5 and / or the vibration signal module 6, opens his eyes for a set time, for example, 0.55 s, the control system gives a command to remove the blackout from screen 1. That is, the voltage is removed from the electrodes, the crystal molecules are rearranged and the glasses return to their original transparent state. After that, glasses 3 can be removed or continue to be in glasses 3 until the next act of relaxation.

If the user in the process of relaxation opened his eyes to the response time of the command to remove the dimming from the screen 1, then the command for the activation of the wake-up LEDs 5 and / or the wake-up vibration module 6 is reset and a second time report starts. Thus, it is possible to extend the time of psychological and emotional relaxation.

Example 2

An individual device for protecting the eyes of pupils of the senior group of the kindergarten from external light influences during sleep is made in the form of a mask (not shown separately).

The mask is performed according to the inventions, adjusted for the maximum permissible functions for children of a given age and the minimum sufficient from the point of view of potential capabilities, for example, the response time of proximity sensors 2 for opening / closing eyes is increased to 1 s, a bell is used as the source of the wake-up signal 7, etc. d.

Children willingly put a mask on their heads and after a joint joint training they begin to “turn off” external light sources on their own. As a result, children fall asleep faster, although there is traditionally a child who unconsciously resists sleep, but there are significantly fewer such children than with the traditional way of falling asleep with windows open to light.

After awakening, children are more collected, obedient and able to perceive large volumes of information, it is better to remember and operate on the information received.

Example 3

A device for protecting the human eye from external light influences during sleep or its imitation is made in the form of a reclining visor 4 on the back of a chair 11, for example, a passenger plane (see Figs. 3 and 4).

The principle of organization and the design of the device is repeated Example 1, adjusted for additional features in terms of the non-contact location of the protective screen 1 with a person’s head, its large dimensions, additional features for organizing the awakening process, more pronounced hygiene and the possibility of use by different people.

The control system can integrate a number of individual devices (according to the number of seats 11 on the plane), which will allow, for example, a flight attendant from their own control panel to provide an individual approach to each passenger, respectively, after they switch on the corresponding service mode at will. As a result, the passenger at the right time will wake up the signal from the keyring of the stewardess. Otherwise, if the service mode was not turned on, then the passenger signal will not wake up, because the radio module 10 (or infrared receiver) will simply not respond to it.

The rest of the work with the device repeats Example 1.

As a result of the use of inventions, a simple way of protecting one’s own organs of vision from external light influences during sleep or its imitation and a device for its implementation was created, which was successfully managed by a person or authorized strangers, which allowed for the successful psychological and emotional unloading of users of different ages.
