Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sleep learning device that detects a half-+111j sleep state and generates, for example, the sound of an English conversation that the user is trying to learn while in this state.

Repetitive learning is important in order to overcome "poor memorization" in learning. It is important to carry out repeated learning by kneading 4 U a day, but it is difficult to maintain it for a long time. During what is known as a time limit, stimuli given repeatedly from the outside (English conversation, music, etc.) are stored in the memory without making the learner feel any difficulty in learning.
Traditionally, this sleep learning method involved making sounds throughout the student's sleep. i
He continued to make sounds during H1 semi-sleep, deep sleep, and regardless of the level of ll1lF sleep. However, this method has problems for both the learning device and the learner (human). Humans are constantly exposed to meaningful noise (learning sounds; noise such as traffic noise is considered meaningless noise) during sleep periods, so if we continue to do so for a long period of time, The user begins to feel sleep deprivation and fatigue, and what is even more inconvenient is that the user becomes unable to distinguish between meaningful noise and non-tasteful noise, and loses the intention of the device t';. Further, the learning sound is repeatedly played back by a normal tape player in the learning device.

Therefore, the tape player must be kept running for 6 to 8 hours every night. As a result, the lifespan of the tape on which the tape play and learning sounds are recorded is significantly shortened, and in particular, the tape can no longer be used.

This invention eliminates the above-mentioned drawbacks of the prior art, extends the lifespan of the learning equipment, and contributes to the application of appropriate stimulation and less effort without causing fatigue or lack of sleep to the learner. The purpose of this study is to provide 4 students with 1 device, which can increase the learning effect.

``This invention's characteristic features'', 1) Detect brain waves, 2) Determine the state of sleep, 5) The goal is to listen to Gakuho's music only at 1 o'clock when he is half asleep.

Brain waves can be roughly classified according to the state of sleep, as shown in Figure 1. (a) Waking state: Brain waves are alpha waves.

(b) Shallow Il! State of sleep: Brain waves are α+β waves.

(c) (b) Deeper sleep state: Brain waves are δ waves (
d) The previous song t0 can be played in four different states. 11+1 that is effective for sleep learning! The sleep state is the light sleep state shown in (b), and the brain wave is 1. with alpha waves and delta waves mixed together.

The frequency components of brain waves are approximately 0.5 H,z ~ 701 (7,
The α wave is mainly composed of 3[:1 to 7011Z f−j degrees, and the δ wave is mainly composed of 0.5 to 41J 117.4″a1 degree components.

The alpha waves and delta waves are extracted from the brain waves using a band pass filter, and the semi-sleep period (state of light sleep 77!) in which both waves are present at the same time is identified.

Even during deep sleep, 2 to 3 minutes 1” IC short time, shallow 1
1. "Even if you are in a sleep state, this will occur. If you activate the learning device every time this happens, there will be no difference from the conventional example, so the light sleep state immediately before waking up will become constant. After it appears, operate the learning device (6).

Also, people usually have dreams under this condition, but they are rarely remembered and forgotten. Applying learning sound during this state,
If you try to eliminate it too quickly, strong brain wave fluctuations may occur for the next hour, causing you to wake up and become confused. Therefore, the application and removal of learning 1~ to the extent that the memory is not lost may be performed by fading in and fading out.

Hereinafter, the present invention will be explained based on the embodiment shown in FIG.

Device d-1 includes an electroencephalogram detector 1, an amplifier 2, a bandpass filter 5FL, 3b, and a level determiner 4a, 4.

It is divided into sections.

The features, operations, etc. of the device (6) will be explained step by step below.

For medical information 1, one electrode is placed on the forehead of the learner (human body), and 114. Paste it with an adhesive with good properties (for example, apply a cloth soaked in saturated saline solution, paste containing salt, etc.). However, in the learning device, this kind of treatment is not possible, so place the electrode 1 on the band-shaped body that is called Headband Association 5. The electrode 1 is crimped onto the forehead by tightening. ′

It is set to 11ΣLT-, which makes it easier for the Tsukugo place Jon in the latter stage. The band filters a and 3b are used to separate alpha waves and delta waves in the brain waves. The main component of αθㅅ is 50~80Hz % The main component of δ wave is 0.5~4

Obi-tied filter 3a! +b band is 30 to 801 respectively
17. .

Any band from 0.5 to 401-fz is sufficient. The outputs of the band wind filters a and 6b are led to level determiners 4a and 4b, respectively. In order to separate the output of the bandpass filter from noise, the level determination 334as4b performs a constant iψ operation such that the output reaches a certain level and outputs an output of -'h level V. 1st, α wave and δ wave question 1
~ Level judgment only if each child is present
, 4a, 4b are detected.

Sleep state, d1, individual time 4ril (for example, 2
It is only necessary to make a judgment every minute). Set the timer 6 times. The pulse generators 5a and 5b output the level determiner 4a at the time 4jj set by the timer 6.

4) Check whether there is an input from [] and generate a pulse only when there is an input. Now use the alpha wave detection system for the threads 3a to 5a.
Letting the system 3b to 5b be the δ wave detection system Z), this shows that α waves are present in the brain waves when pulses are generated from the pulse generator 5a. The adder 'I'1 unit 7 is activated only when pulses are applied simultaneously from the pulse generators 5a and 5b (
(Only when alpha and delta waves exist simultaneously in the light sleep state shown in Figure 1(b)) output is produced.

With the above steps, we were able to detect a light sleep state. However, as mentioned above, even during ripe + 11j, it often happens that you sleep for about 2 to 3 minutes and then go into a light sleep state for 0 hours.
In this device 1'1, a clock (timer) 8 is provided,
The output of the adder 7 is synchronized with the timer 6 to count whether or not the output has occurred consecutively and how many times the output has not occurred consecutively, and when a preset number of times has been reached, the control signal is output. Generator 9 is activated.

In the embodiment, the time interval of the timer 6 is set to 2.5) and 7.
We determined the existence of α waves and δ waves in two molecules σ. Callan 8 counts the output from the ka-leopter 7, and when the output is turned on four times in a row (6 minutes) (alpha waves and δ waves are simultaneously present [7 - shallow + 111 s 6 minutes after entering the sleep state (11 elapsed), the control signal generator 9 is made to generate an output (ON state).

It's amazing, when there was no output from Kabao device 7 for 6 consecutive times (
(6 minutes have passed since the state of wakefulness or deep sleep) The output 9b of the control signal generator 9 is set to zero (OI
i'Ii': state). The output 9a becomes zero (OFF state) after increasing by +1φ after the time described below.The output signal of the control signal generator 9 is the learning signal generator 10,
