Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an alarm clock that notifies sleep time.

[Conventional technology]

Conventionally, there are no clocks that notify people of their sleep time, and sleep time is determined by calculating the time from the time they go to bed to the time they wake up.

[Problem that the invention seeks to solve]

It is necessary to always keep track of sleep time for health management, but it is extremely difficult to determine sleep time by mental calculation every day.

In order to eliminate this inconvenience, the present invention provides a display or audio notification of sleep time when the alarm is turned off.

[Means for solving problems]

The present invention provides a notification device that determines the time from the time when a detection circuit detects that the lights are turned off to the time when the alarm is turned off or until the alarm time, and notifies this time as sleep time when the sound is turned off. It is something.

〔Example〕

In Figure 1, 1 is an oscillator, 2 is a frequency divider, 3
1 is a drive circuit for a motor 4, and the motor 4 is used to advance a time display hand (not shown). 5,
Reference numerals 6 and 7 are sound generation circuits, and the sound generation circuit 5 generates a message urging the alarm to be set, such as "Are you sure you want to set the alarm?" when the alarm is not set when the light is turned off, and the sound generation circuit 6 generates a message prompting the alarm to be set when the light is turned off. When an alarm has been set, a message confirming the alarm set, such as "Alarm set O.K.", is generated. The voice generating circuit 7 generates a message informing the user of sleep time, such as "You have been absent for XX hours and XX minutes." Reference numeral 8 is an alarm circuit, 9 is a sounding device, and 10 is a timing circuit, which measures the time from when the lights are turned off to when the alarm is turned off. 11 is a latch circuit, 12 is a one-shot circuit that generates a pulse with a width of about 5 seconds, and 13 is a light emitting device. 14~
18 is a gate circuit, 19 is an inverter, 20,2
1 is a differential circuit. 22 is a phototransistor, 23 is a resistor, 24 is a differential circuit, 25 is a level detection circuit, 26 is a timer circuit set to, for example, 10 seconds, and 27 is a gate circuit, which constitute a detection circuit. 28 is an alarm set switch, and 29 is an alarm switch.

Next, the operation will be explained. Assume that the alarm set switch 28 is now closed and the alarm is set. As a result, gate circuit 1
5 and 16 are open. Generally, the lights are turned on before going to bed, and the lights are turned off before going to bed. When the illumination is on, the phototransistor 22 is on, and when the illumination is turned off, the phototransistor 11 changes rapidly from on to off, and the differentiation circuit 24 generates a differential pulse. The timer circuit 26 is operated by this differential pulse, and 10
A pulse occurs after a second. On the other hand, the level detection circuit 25 produces an output when the surroundings are at a certain level or higher and is dark, and when this output and the pulse from the timer circuit 26 occur simultaneously, it is assumed that the light is turned off. For example, if a person crosses in front of this clock device and enters the shadow, it will suddenly become dark, so the differential circuit 2
A pulse is generated from 4, but in this case the dark time is instantaneous, and after 10 seconds the timer circuit 2
When the pulse is generated from 6, it is already bright and no output from the level detection circuit 25 is generated. Therefore, in such a case, the light is not considered to be off, but only when it is dark even 10 seconds after the differential pulse is generated.

When it is detected that the light is turned off in this way, the gate circuit 27
A pulse is generated from the sound generating circuit 6 through the gate circuit 16, which generates the message "Alarm set OK."
will be notified from.

On the other hand, the clock circuit 10 is reset by the pulse from the gate circuit 27. Timing circuit 10
receives the pulse from the frequency divider 2, and starts measuring time from the time when the lights are turned off, that is, starts measuring sleep time.

When the alarm switch 29 closes at the alarm time the next morning, an alarm signal is generated from the alarm circuit 8 by the output of the gate circuit 15, and an alarm sound is generated from the sound generating device 9. When the alarm set switch 28 is opened to stop the alarm from ringing, a pulse is generated from the differentiating circuit 20 and supplied to the latch circuit 11 via the gate circuit 18. Therefore, the contents of the clock circuit 10 at this time, that is, the sleep time, are latched in the latch circuit 11, and as a result, a message saying "You have been absent for XX hours and XX minutes" is generated from the voice generation circuit 7. Notification is made from the sounding device 9.

Next, we will explain what happens when you forget to set the alarm and go to bed. When the user tries to sleep with the alarm set switch 28 open and turns off the light, a pulse from the gate circuit 27 is supplied to the sound generation circuit 5 via the gate circuit 14. The sound generation circuit 5 generates a message saying "Are you sure you want to set the alarm?" and the sound generation device 9 issues a message. On the other hand, the pulse from the gate circuit 14 generates a pulse of about 5 seconds from the one shot circuit 12, and the light emitting device 13 lights up. This light emitting device 13 is located near an operating member (not shown) of the alarm set switch 28, so that the operating member can be found even after the light is turned off, and the alarm can be easily set. When the alarm is set after the lights are turned off, the clock circuit 10 is reset by a pulse from the differentiating circuit 21 and starts counting sleep time.

The subsequent operations are exactly the same as above.

Note that when going to bed when it is bright, such as during the daytime, no pulse is generated from the differentiating circuit 24. Therefore, in this case, the time when the alarm set switch 28 is closed and the alarm is set is considered to be the time when the person goes to bed, and the clock circuit 10 is reset to start clocking.

Figure 2 shows an example of use in an all-electronic watch.
In the figure, 30 is a current time clock circuit; 31
3 is an alarm time setting circuit, and 32 is a coincidence circuit. Numerals 33 and 34 are latch circuits in which the time when the light is turned off and the time when the sound is turned off are latched, respectively.

35 is an arithmetic circuit that calculates the time from when the lights are turned off to when the sound stops. The same numbers as in FIG. 1 indicate the same things.

In the above configuration, the gate circuit 2 when the light is turned off
The current time, that is, the bedtime, is latched in the latch circuit 33 by the pulse from 7. At this time, depending on whether an alarm is set or not, a message is generated from either the voice generating circuit 5 or 6 in exactly the same way as above.

When the next morning's alarm time comes with the alarm set, an output is generated from the matching circuit 32, and an output from the gate circuit 15 causes the alarm circuit 8 to be activated.
An alarm signal is generated and an alarm sound is generated.

When the alarm set switch 28 is opened to stop the alarm from ringing, a pulse is generated from the differentiating circuit 20 and passes through the gate circuit 18. This pulse causes the current time, that is, the wake-up time, to be latched in the latch circuit 34, and the calculation circuit 35 calculates the time from the bedtime to the wake-up time, that is, the sleeping time. As a result, the sound generation circuit 7 generates a message informing the sleep time, and the sound generation device 9 issues the message.

In each of the above embodiments, sleep time is notified by voice, but it may be notified by display.

Furthermore, in each of the embodiments described above, the time from when the lights are turned off to when the alarm is turned off is reported as sleep time, but the time from when the lights are turned off until the alarm time may be reported.

Although the brightness of the surroundings changes frequently, if the change from bright to dark is gradual, the differentiating circuit 24 does not generate a pulse. Generally, in daily life, the only time there is a sudden change from bright to dark is when the lights are turned off, and there is very little risk of generating sounds at unnecessary times.

〔effect〕

According to the present invention, when the lights are turned off, the time from when the lights are turned off to when the sound is turned off or when the alarm is turned off is notified as sleep time, so there is no need for any special operation. You can know your sleep time.

Furthermore, by determining whether or not an alarm has been set when detecting that the light is off, and notifying the user of this fact, it is possible to prevent forgetting to set the alarm.

Furthermore, by lighting the light emitting element for a certain period of time when it is determined that the alarm is not set,
At this time, the lights are already off and it is dark, but you can see where the clock is and easily set the alarm.
