Abstract
본 발명은 손목 시계 형태인 자명종 내에 부착한 맥파 검출기에 의해, 사용자가 설정한 기상 시각이 되기 전 90분 이내에 발생한 렘수면을 체크하여, 해당 렘수면이 끝난 후 바로 자명종이 울리도록 함으로써 사용자가 상쾌하게 잠에서 깨어나도록 유도한다. 렘수면 바로 다음 단계가 수면이 가장 얕은 단계이며 보통 이 단계에서 편안하고 자연스럽게 잠에서 깨어난다.The present invention checks the REM sleep generated within 90 minutes before the user's wake-up time by the pulse wave detector attached to the alarm clock in the form of a wrist watch, so that the alarm clock sounds immediately after the REM sleep ends. Induce to wake up. The next stage of REM sleep is the shallowest stage of sleep and usually wakes you up naturally and comfortably.
Description
본 발명은 맥파로 부터 수면이 가장 얕은 단계를 체크하여 사용자가 설정한 시각 전 가장 쾌적하게 기상할 수 있는 시점에서 자명종이 울리도록 하는 시스템이다. 이전 많은 연구자들이 수면시에 주기적인 수면 단계가 반복됨을 발견하였다. 그 중 1957년에 Dement와 Kleitman에 의해 제안된 수면 단계 구분법이 십 여년 동안의 수백명의 연구자들에 의한 많은 연구결과에 근거하여 유용함이 증명되었다. 결국 수면 정신생리학회(Association for the Psychophysiological Study of Sleep:APSS)에서 수면 단계의 표준 점수화 시스템(standard scoring system for stages of sleep)으로 채택하게 되었다. 이후 별다른 큰 수정 없이 전세계 임상 의사들 및 연구자들이 수면 검사시에 적용하고 있다.The present invention is a system that checks the shallowest stage of sleep from the pulse wave so that the alarm clock sounds when the user can wake up most comfortably before the time set by the user. Many researchers have found that the regular sleep phases are repeated during sleep. Among them, the sleep stage classification method proposed by Dement and Kleitman in 1957 proved to be useful based on many studies by hundreds of researchers over a decade. Eventually, the Association for the Psychophysiological Study of Sleep (APSS) was adopted as the standard scoring system for stages of sleep. Since then, clinicians and researchers around the world are applying sleep tests without major modifications.
기존의 자명종은 사용자의 수면상태에 대한 배려가 전혀 이뤄지지 않고 있다. 즉, 기존의 자명종은 사용자가 설정한 시각에 무조건 울림으로써, 흔히 깊은 수면 상태에서 각성 상태로 강제 전환시켜 사용자에게 불쾌감, 피로감, 짜증감을 유발한다.Existing alarm clocks do not consider the user's sleep status at all. In other words, the existing alarm clock is unconditionally ringing at the time set by the user, often forced to switch from the deep sleep state to the awake state, causing discomfort, fatigue, irritability to the user.
본 발명에서는 가장 얕은 수면단계에서 자명종을 울리게 하여 사용자가 상쾌하게 기상할 수 있도록 함으로써 기존 자명종의 문제점을 극복한다. 렘수면 바로 다음 단계가 수면이 가장 얕은 단계이며 보통 이 단계에서 편안하고 자연스럽게 잠에서 깨어난다. 렘수면 단계는 뇌파로부터 추출이 용이하나 뇌파 검출기를 머리에 부착해야하는 번거로움이 있다. 본 발명에서는 손목시계형 자명종 내에 맥파 검출기를 부착함으로써 사용자가 보통의 손목 시계를 착용하듯이 편안하게 이용할 수 있도록 한다. 이상의 맥파 검출기가 부착된 손목 시계형 자명종은 맥파로부터 렘수면 단계의 특징들을 추출하여 이를 손목 시계형 자명종에 활용하는 기술이다.The present invention overcomes the problems of the existing alarm clock by ringing the alarm clock in the shallowest sleep stage to enable the user to wake up freshly. The next stage of REM sleep is the shallowest stage of sleep and usually wakes you up naturally and comfortably. The REM sleep phase is easy to extract from EEG, but it is cumbersome to attach an EEG detector to the head. In the present invention, by attaching the pulse wave detector in the wristwatch alarm clock, the user can use comfortably as if wearing a normal wrist watch. The wristwatch alarm clock with the above-described pulse wave detector is a technology that extracts the characteristics of REM sleep stage from the pulse wave and uses it in the wristwatch alarm clock.
도 1은 본 발명에 따른 시스템 구성의 개략적인 다이아그램.1 is a schematic diagram of a system configuration according to the present invention.
도 2는 맥파의 처리절차를 나타내는 플로챠트2 is a flow chart showing a pulse wave processing procedure
본 발명은 도면 1과 같이 손목 시계형으로 크게 맥파 측정부와 맥파 처리부, 자명종 작동부로 나뉜다. 맥파 측정부는 맥파 감지부, 맥파 증폭부, A/D 변환부로 구성된다. 맥파 감지부는 손목 시계형 타입으로 사용자가 착용하기 편한 형태이다. 맥파 처리부는 수면 단계 중 렘 수면단계를 실시간 검출하여 렘 수면이 끝난 후 트리거 신호를 출력한다. 자명종 작동부는 설정된 시각 전 90분 이내에 트리거 신호가 발생했는지를 체크하여 손목시계형 자명종이 울리도록 한다.The present invention is a wrist watch type as shown in Fig. 1 is largely divided into a pulse wave measuring unit, a pulse wave processing unit, an alarm clock operating unit. The pulse wave measuring unit includes a pulse wave detector, a pulse wave amplifier, and an A / D converter. The pulse wave detector is a wrist watch type that is easy to be worn by a user. The pulse wave processor detects the REM sleep phase in real time during the sleep phase and outputs a trigger signal after the REM sleep is finished. The alarm clock operator checks if a trigger signal is generated within 90 minutes before the set time, so that the alarm clock sounds.
본 발명은 자명종 시계에 설정된 시각이 되기 전 90분 이내에 발생한 렘 수면을 체크하여, 렘 수면이 끝난 후인 가장 얕은 수면단계에서 자명종이 울리도록 함으로써 상쾌하게 잠에서 깨어나도록 유도한다.The present invention checks the REM sleep generated within 90 minutes before the time set in the alarm clock, so that the alarm clock rings at the shallowest sleep stage after the REM sleep is induced to wake up freshly.
일반적인 자명종은 흔히 깊은 수면 상태에서 각성 상태로 강제 전환시킴으로써 사용자에게 불쾌감, 피로감, 짜증감을 유발하곤 한다. 본 발명은 신체적으로 각성할 준비가 된 상태에서 사용자가 설정한 시간 내에 기상할 수 있도록 한다. 이는 신체에 부담을 최소화하고 정신적으로는 쾌적한 상태를 유발함으로써 만성적인 피로감을 없애고 생활에 활기를 부여할 수 있다.Common alarm clocks often cause discomfort, fatigue and irritability to the user by forcing a transition from deep sleep to arousal. The present invention allows the user to wake up within a time set by the user in a state of being ready to wake up physically. This minimizes the burden on the body and causes a mentally pleasant state to eliminate chronic fatigue and energize life.
