Abstract

PURPOSE:To make a user wake up at a desired time, by a method wherein the conscious state of the user from a brain wave measured and the amount of electronic sound is varied as generated based on the results of the detection so as to keep him asleep without feeling discomfortable according to the conscious of the user. CONSTITUTION:When sleep operation is started at the time t1, the outputs B and C go to H to keep the output D at H. An audible sound is generated from a sound generation circuit 22 to enable the operation B at a sound volume specifying circuit 54. Under such a condition, when the user is awake, only betawave is detected 60 from a signal from a brain wave detector section 56, the output G1 moves to H while the sound volume specifying signal H1 to H to turn ON an analog switch 46 so that the audible sound will be generated at a large volume to promote the sleeping of the user. At the time t6, as the set time is reached, an alarm start signal is outputted to the output A and an audible sound is generated from the circuit 22. Under such a condition, when the user is in sleep, theta wave is detected 64 ad the output G3 moves to H while the signal H1 to H. Thus, a switch 46 is turned ON and the audible sound is generated at a large volume to prompt the awakening of the user.

Furthermore, in this embodiment, a sound generation automatic stop circuit 84 is provided, and the sound generation operation is automatically stopped when the user's falling asleep state is detected for a certain period of time when the sleep function is activated, and the user's awake state is detected for a certain period of time when the alarm function is activated. It is structured like this.

The AND gate 86 detects the sleep state of the user during the sleep function, and includes output B, output G3, and inverted output G.
2 is supplied. On the other hand, the AND gate 88 detects the wakefulness state of the user during the alarm function, and is supplied with the inverted outputs B and G1.

The output K, which is supplied to the reset terminal R of the counter 92 and generates the carry signal of the counter 92, is output to the audio frequency signal generating circuit 1.
It is supplied to OR gates 34 and 35 in 6.

The present embodiment has the above configuration, and its operation will be explained below based on FIG. 3.

At time t, when the sleep onset operation is started, the output B and the output C become rH, and thereby the output R is held at "H". Therefore, the sound generation circuit 22 generates an audible sound, the volume designation circuit 54 becomes active in operation B, and furthermore, the brain wave detection operation is started. If the user is awake in this state, only β waves will be detected, and therefore the output G,
becomes "H". Therefore, the volume designation signal H1 becomes "H" and the analog switch 46 is turned on, so that the audible sound is generated at a high volume and the user is encouraged to fall asleep.

Thereafter, at time t2, when the user enters a resting state, alpha waves are detected instead of beta waves, and therefore the negative output becomes rHJ. Therefore, here, the volume designation circuit mountain is “H”.
”, the analog switch 48 is turned on, an audible sound is generated at a medium volume, and the stimulation to the user is adapted to a resting state. When the user becomes dazed (at time ta), α waves are generated. and θ wave are detected, so output G2 and output G3 are rHJ
Therefore, the volume designation signal ratio becomes "H".

Therefore, the analog switch 50 is turned on and an audible sound is generated at a low volume, so that the stimulation to the user is adapted to this condition. Then, when the user falls asleep (time 1
4) Since only the θ wave is detected, only the output G3 becomes rHJ, and the volume designation signal ratio continues to be "H". Therefore, the analog switch 50 remains on and the audible sound is generated at a low volume.

At this time, the output 1 of the AND gate 86 becomes rHJ, so the output J becomes rLJ and the reset of the counter 92 is released. Therefore, the counting operation of the counter 92 is started, and when this state continues for a certain period of time, for example, one minute, and a carry signal is output to the output K, this carry signal is supplied to the OR gates 34 and 35. Therefore, since FF28 and FF32 are both reset, output B and output
As a result, the audible sound from the sound generation circuit 22 is no longer generated, and the sleep-inducing operation is automatically stopped (at time t
5) 0 If an alpha wave is detected during the counting operation of the naori counter 92, the output J becomes "H" and the counter 92 is reset, and if the alpha wave is no longer detected after that, the counting operation resumes from the initial state. will be carried out. In other words, the device is configured to stop the sleep-inducing operation only when the user has definitely fallen asleep.

Next, at time t6, when the set time arrives, an alarm start signal is output to output A, and as described above, the sound generation circuit 2
An audible sound is generated from 2. At the same time, the volume designation circuit 54 becomes active in operation A, and further brain wave detection operation is started. If the user is falling asleep in this state, the θ wave is detected, so the output G becomes IHJ, and the volume designation signal H is used to urge the user to wake up.

Thereafter, at time t7, when the user enters a dazed state, alpha waves and t waves are detected, so the output can and output G become rHJ, and the volume designation signal ratio becomes rHJ. Accordingly, the analog switch 48 is turned on and an audible sound is generated at a medium volume so that the stimulation to the user is adapted to the dazed state.

Thereafter, when the user is in a resting state (time ta), since alpha waves are detected, the output G2 becomes rHJ, and the volume designation signal ratio becomes rHJ. Accordingly, the analog switch 50 is turned on and an audible sound is generated at a low volume so that the stimulation to the user is matched to a resting state. Then, when the user becomes awake (time to), β waves are detected, so the output G,
becomes rHJ, and the volume designation signal ratio continues to be "H". Therefore, the analog switch 50 remains on and the audible sound is generated at a low volume.

Here, the output 2 of the AND gate 88 becomes rHJ, so the output J becomes "L". Therefore, as mentioned above, since the reset of the counter 92 is canceled, if this state continues for a certain period of time, a carry signal will be output to the output K, and the alarm operation will be automatically stopped here. (Time t
,. ). Of course, by closing the ringing stop switch 36 before this, the alarm operation can be forcibly stopped.

(Effects of the Invention) As described above, in this embodiment, the volume of the audible sound generated when the user performs the falling asleep action is reduced in accordance with the state of consciousness of the user, so that the volume does not cause discomfort to the user. It can help you fall asleep, and when the wake-up operation is performed at the set time, the volume of the audible sound that is generated decreases according to the user's state of consciousness, so it does not give the user more stimulation than necessary. As a result, it is possible to encourage a comfortable wake-up even at the set time.

Furthermore, in this embodiment, by providing the automatic sound generation stop circuit 84, the processing after the user falls asleep or wakes up is omitted, so that even more comfort can be provided.

In addition, in the operation of this embodiment, the falling asleep operation was explained from the awake state, and the waking up operation was explained from the falling asleep state.
Of course, this is not limited to this, and even if the movement is started in another state of consciousness, the sound will be generated at a volume that is appropriate for that state of consciousness. No need to be surprised.

As described above, according to the present invention, it is possible to provide a watch that has both a sleep-falling function that allows you to fall asleep without causing discomfort, and an alarm function that allows you to comfortably wake up at a desired time. can.
