Abstract

PROBLEM TO BE SOLVED: To provide a sleep cycle alarm timepiece capable of notifying a person of time to conformably wake up by combining a device for detecting the time of having gone to sleep with a clock with an alarm device and issuing an alarm in every sleep cycle of 90 minutes on the basis that 90 minutes are one cycle in human sleep with REM sleep and non-REM sleep combined together and that he can be refreshed and wake up in one and a half hours, three hours, four and a half hours, six hours, seven and a half hours, or nine hours after going to sleep. SOLUTION: It is utilized that the electric resistance of an organism changes in a human before and after going to sleep. An organism electric resistance measuring device is built in part of the back lid of a watch with an alarm device to measure changes in electric resistance at part of a wrist before and after going to sleep. When a predetermined rise is detected, the time of having gone to sleep is determined to be a signal to turn on the alarm which sounds in a cycle of 90 minutes.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention incorporates a "bioelectric resistance measurement device" in the back cover of a wristwatch equipped with an alarm device, and has an electrode for weak high-frequency current and an electrode for bioelectric resistance detection, respectively. Place it on the wrist of the back of the watch and on the part that comes in contact with the bottom of the wrist of the watch band, embed a lead wire in the watch band, connect the `` bioelectric resistance measurement device '' and the electrode part, This is a clock capable of detecting the time of falling asleep using the increase in electrical resistance of a living body after falling asleep and sounding a 90-minute cycle alarm. A clock that detects the time of falling asleep and sounds an alarm in a 90-minute cycle has never been made. RJ in the United States
There are four electrodes from L Systems, which can measure the electrical resistance (impedance) of a living body with considerable accuracy. Human sleep is repeated as a set of non-REM sleep and REM sleep. The sleep of this one set (one cycle) is about one hour and thirty minutes (90 minutes), and this is repeated several times in a normal person's daily sleep. When a person sleeps, non-REM sleep and REM sleep occur in this order, and the total duration of these two sleeps is about 90 minutes. No, you can wake up most clearly. Then, after we fall asleep, we wake up most clearly at 1 hour 30 minutes, 3 hours, 4 hours 30 minutes, 6 hours, 7 hours 30 minutes, and 9 hours It is time to be able to do things. So, using this 1 hour and 30 minute cycle, after falling asleep 1 hour and 30 minutes and 3 hours later,
It is very convenient if there is a clock that gives an alarm sound after 4 hours 30 minutes, 6 hours, 7 hours 30 minutes, and the like. However, if the time of falling asleep is not known, the subsequent one and a half hour cycle cannot be notified by an alarm sound. The sleep time is set by the person by deciding to sleep several minutes later. It is worth making and using such a watch, but this is inaccurate. When a person falls asleep, bioelectric resistance (bioimpedance) increases. Therefore, the difference between the bioelectrical resistance before and after falling asleep is sensed by the bioelectrical resistance measuring device, the sleep onset time is known, the alarm is activated, and then about 1 hour 30
It is convenient to make a clock that sounds an alarm every minute. The electrical resistance of the living body is the part where the watch is attached,
It is most convenient to measure at the wrist. In a wristwatch-type sleep cycle alarm clock, a “bioelectric resistance measurement device” is built in the back cover of the clock. On the wrist (the back of the hand) where the case back of the watch contacts,
Each part of the watch band that comes in contact with the bottom of the wrist (palm side) has an electrode that sends a weak high-frequency current and an electrode that detects bioelectric resistance, and the watch band uses an electrical insulator such as leather. A lead wire is embedded, and four electrodes are connected to the "bioelectric resistance measurement device" built in the back cover with four lead wires. Then, this watch has a built-in four-electrode "bioelectric resistance measuring device" and measures the electric resistance of the wrist before and after falling asleep. A person using the "sleep cycle alarm clock" switches on the "bioelectric resistance measuring device" built in the clock before going to bed. This measuring device measures the bioelectric resistance of the wrist at intervals of about 5 minutes, for example. If the electrical resistance rises beyond a certain value from the measured value when the switch is turned on, 9
Turn on the switch to set the 0 minute cycle alarm. As described above, a clock that combines the “90-minute sleep cycle” and the “bioelectric resistance measurement device” that detects an increase in bioelectric resistance during falling asleep is a “sleep cycle alarm clock”. This "sleep cycle alarm clock" works to signal a comfortable wake-up time, but can also be used for a short sleep. Modern people are busy and often cannot afford to sleep for a long time. "8
Many researchers believe that time sleep is necessary. In fact, not a few people sleep three hours a day. If you use a "sleep cycle alarm clock", set an alarm sound for 1 hour and 30 minutes for one cycle, 1 hour and 30 minutes for 1 cycle, 2 hours and 3 hours for a longer cycle, and 4 hours and 30 minutes for 3 cycles. You can take it freely. The “sleep cycle alarm clock” is effective for executing a short sleep. It is a watch that promises both "sleep that can wake up comfortably" and "short sleep" to busy modern businessmen. One sleep cycle is about 90 minutes (1 hour and 30 minutes), but it is thought that there is a slight difference in the time depending on the person, so one sleep cycle can be adjusted in a range of about "1 hour 30 minutes ± 15 minutes". "Sleep cycle alarm clock" is desirable. If the "sleep cycle alarm clock" is a wristwatch type, a "bioelectric resistance measurement device" is built in the back cover of the watch, and two electrodes for weak high-frequency current and two electrodes for bioelectric resistance detection are clocked. It is installed in the part that comes in contact with under the wrist of the band, and a lead wire is embedded in the watch band to connect the "bioelectric resistance measurement device" and the electrode part. Then, as described above, the sleep onset time is detected and an alarm of a 90 minute cycle can be sounded. In the case of an alarm clock type, the alarm device is separated from the wristwatch and attached to the alarm. If the bioelectric resistance rises above a certain level,
Radio waves can be used to turn on a switch that activates an alarm on a bedside or other alarm clock.
