Description

Die Erfindung betrifft ein Verfahren zum Wecken einer Person mittels einer Weckeinrichtung, umfassend eine Weckvorrichtung und einen über Funk mit der Weckvorrichtung gekoppelten Bewegungssensor, wobei die Bewegungen der schlafenden Person zum Auslösen eines Weckvorganges herangezogen werden, sowie eine Weckeinrichtung zur Durchführung des Verfahrens.The invention relates to a method for awakening a person by means of a wake-up device, comprising a wake-up device and a motion sensor coupled via radio with the wake-up device, wherein the movements of the sleeping person are used to trigger a wake-up, and a wake-up device for performing the method.

Um den Anforderungen des täglichen Lebens in einer von Zeit dominierten Welt gewachsen zu sein, ist es notwendig, den Lebensrhythmus nicht den persönlichen Bedürfnissen sondern den gegebenen Bedingungen anzupassen. Es ist selten möglich, die Tageszeit unabhängig von Geschäfts- und Freizeitterminen allein nach physiologischen Gesichtspunkten in aktive Phasen und Ruhephasen einzuteilen. Um so wichtiger ist es daher, zumindest die Zeit, in der geschlafen wird, bestmöglich zur Erholung zu nutzen und damit die körperliche wie auch die geistige Leistungsfähigkeit zu sichern bzw. sogar zu verbessern.In order to cope with the demands of everyday life in a time-dominated world, it is necessary to adapt the rhythm of life not to the personal needs but to the given conditions. It is seldom possible to divide the time of day independently of business and leisure appointments into active phases and phases of rest only according to physiological considerations. Therefore, it is all the more important to use the time in which you sleep for the best possible relaxation and thus to secure and even improve your physical and mental performance.

Es ist seit geraumer Zeit bekannt, dass der menschliche Schlaf nicht gleichförmig verläuft, sondern Tiefschlafphasen mit Leichtschlafphasen (Aktivschlafphasen), sogenannten REM-Phasen, alternieren. Eine solche REM-Phase, die eine Zeit erhöhter Traumaktivität darstellt, tritt etwa alle 100 Minuten mit einer Dauer von 10 bis 30 Minuten ungefähr 4 bis 6 Male bei normalem Schlafablauf auf. Mit zunehmender Schlafdauer werden die Tiefschlafphasen kontinuierlich kürzer und weniger tief, die REM-Phasen hingegen immer länger. Eine unnatürliche Unterbrechung oder eine Verringerung bestimmter Schlafphasen kann zu funktionell psychischen Störungen führen, beispielsweise zu starker Übermüdung, gereizter Stimmung, auffälliger Konzentrationsschwäche oder sogar zu Angstzuständen.It has been known for some time that human sleep does not proceed uniformly, but instead alternates deep sleep phases with light sleep phases (active sleep phases), so-called REM phases. Such a REM phase, which is a time of increased dream activity, occurs about every 4 to 10 minutes approximately every 100 minutes, with a duration of 10 to 30 minutes, during normal sleep. With increasing sleep duration the deep sleep phases become continuously shorter and less deep, while the REM phases become longer and longer. An unnatural interruption or reduction of certain sleep phases can lead to functional mental disorders, such as excessive fatigue, irritable mood, conspicuous lack of concentration or even anxiety.

Es sind Verfahren und Vorrichtungen zum Wecken mit mechanischen, elektromechanischen und elektrischen Weckern bekannt, z.B. aus der DE-A - 2405771 , die in Abhängigkeit von einer vorgebbaren, beispielsweise einstellbaren oder programmierbaren Weckzeit akustische, optische oder taktile Reize erzeugen. Nachteilig ist dabei, dass die Reize unabhängig vom Schlafzustand des Aufzuweckenden erfolgen.There are methods and devices for awakening with mechanical, electro-mechanical and electrical alarm clocks known, for example from DE-A-2405771 which generate acoustic, optical or tactile stimuli as a function of a predefinable, for example adjustable or programmable wake-up time. The disadvantage here is that the stimuli occur regardless of the sleep state of the awakening.

Ebenfalls bekannt sind ein Verfahren und eine Vorrichtung, die ein Wecken unmittelbar nach einer Traumphase, also einer REM-Phase, ermöglichen, so dass die geweckte Person in der Lage ist, ihren Traum zu rekonstruieren ( DE-A - 3102239 ). Der Nachteil dabei besteht jedoch darin, dass das Wecken unabhängig von einer einstellbaren Weckzeit erfolgt und dass der Schlafende durch Sensoren an den Augen und über Drahtverbindungen mit der Weckeinrichtung verbunden ist.Also known are a method and a device which enable awakening immediately after a dream phase, ie a REM phase, so that the awakened person is able to reconstruct their dream ( DE-A - 3102239 ). The disadvantage here, however, is that the awakening is done independently of an adjustable wake-up time and that the Sleeping is connected by sensors on the eyes and via wire connections with the alarm clock.

Aus der EP-A ― 0 496 196 und der DE-A ― 42 09 336 sind Verfahren zum Wecken bekannt, bei denen die Körperbewegungen des Schläfers über die Schlafzeit hinweg gemessen und für die Ermittlung des Schlafzustandes herangezogen werden, aufgrund dessen ein Weckvorgang zu einem bestimmten erwünschten Zeitpunkt ausgelöst werden kann.From EP-A - 0 496 196 and DE-A - 42 09 336 methods for awakening are known in which the body movements of the sleeper measured over the sleep time and used for the determination of the sleep state, due to a wake-up to a certain desired time can be triggered.

Gemäß DE-A ― 197 41 724 wird zur Ermittlung des REM-Schlafes die Messung des Muskeltonus verwendet, der bei Erreichen der REM-Phase signifikant abfällt.According to DE-A-197 41 724, the measurement of the muscle tone is used to determine the REM sleep, which decreases significantly when reaching the REM phase.

In der DE-A ― 196 42 316 und der DE-A ― 43 03 933 sind Einrichtungen zum Wecken beschrieben, bei denen ein mit einer Weckvorrichtung drahtlos gekoppelter Sensor zur Ermittlung der Schlafphasen vorgesehen ist, wobei die Weckvorrichtung nach variablen vorgebbaren Bedingungen während einer bestimmten Schlafphase aktiviert wird.In DE-A - 196 42 316 and DE-A - 43 03 933 devices are described for awakening, in which a wirelessly coupled to a wake-up sensor for detecting the sleep phases is provided, wherein the alarm device according to variable predefinable conditions during a certain Sleep phase is activated.

In der Patentschrift DD 263 238 ist ein Verfahren zum Wecken geoffenbart, bei dem nach Registrierung einer Weckzeit und einer Weckzeittoleranz der Schlafzustand der zu weckenden Person dauernd oder zeitweilig abgetestet, die aktuelle Zeit mit einem aus Zeit und Toleranz berechneten Weckzeittoleranzbereich verglichen wird und nur dann geweckt wird, wenn der aktuelle Zeitpunkt beim oder im Weckzeittoleranzbereich liegt und keine ungünstige Schlafphase vorliegt oder wenn der Weckzeittoleranzbereich zu Ende ist. Die Feststellung des Schlafzustands erfolgt über die Messung physiologischer Parameter, wie Puls, Atemfrequenz, Hautfeuchte, Temperatur, Gehirnströme und dgl.In the Patent DD 263 238 a method for awakening is disclosed, in which, after registering an alarm time and a waking time tolerance, the sleep state of the person to be awakened is continuously or temporarily tested, the current time is compared with a time interval and tolerance calculated waking time tolerance range and is only awakened when the current time at or in the wake-up time tolerance range and there is no unfavorable sleep phase or when the wake-up time tolerance range is over. The determination of the sleep state via the measurement of physiological parameters, such as pulse, respiratory rate, skin moisture, temperature, brain waves and the like.

Nachteilig bei diesem Verfahren ist der Umstand, dass die Messung der Parameter gesteuert erfolgen muß und nicht durch Änderung eines gemessenen Parameters selbsttätig ausgelöst werden kann, woraus eine höhere Anzahl an Messungen zur sicheren Feststellung des Schlafzustands resultiert und der Schlafende damit einer höheren Belastung durch elektromagnetische Wellen, Funkwellen oder sonstige Strahlung ausgesetzt ist. Zudem erfordern die meisten physiologischen Parameter aufwendige und für den Schlafenden zumeist unbequeme und teilweise ständig mit einer Verarbeitungseinheit verbundene Meßeinrichtungen, die den Schlaf beeinträchtigen können.A disadvantage of this method is the fact that the measurement of the parameters must be controlled and can not be triggered automatically by changing a measured parameter, resulting in a higher number of measurements for safe detection of sleep state and the sleeper thus a higher exposure to electromagnetic waves , Radio waves or other radiation is exposed. In addition, most physiological parameters require complex and for the sleepy mostly inconvenient and sometimes permanently connected to a processing unit measuring devices that can affect sleep.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, ein Verfahren und eine Einrichtung zum Wecken bereitzustellen, die den Schlafenden keiner unnötigen Belastung aussetzt und seine Schlafqualität nicht mindert, gleichzeitig jedoch ein Wecken in einem für den Schlafenden günstigen Schlafzustand ermöglicht, so dass die Voraussetzungen für eine Verbesserung oder Aufrechterhaltung der Leistungsfähigkeit gewährleistet sind.The object of the invention is to avoid these disadvantages and difficulties, and has as its object to provide a method and a device for awakening, which does not put the sleeping person under any unnecessary stress and does not diminish his quality of sleep, At the same time, however, it allows awakening in a sleeping state favorable for the sleeping person, so that the conditions for an improvement or maintenance of the efficiency are ensured.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass erst nach Registrierung einer Bewegung durch den Sensor die Koppelung zwischen Weckvorrichtung und Bewegungssensor aktiviert wird.This object is achieved in that only after registration of a movement by the sensor, the coupling between the alarm and motion sensor is activated.

Die vorliegende Erfindung beruht auf der Entdeckung, dass die Bewegungen eines Menschen im Schlaf mit bestimmten Schlafphasen in Zusammenhang stehen. Es wurde festgestellt, dass es zu Beginn und am Ende bestimmter Schlafphasen verstärkt zu Körperbewegungen kommt, wodurch es möglich ist, die einzelnen Schlafphasen voneinander zu unterscheiden. Werden die Bewegungen während des Schlafs verfolgt, so läßt sich ein bestimmtes Muster von Leichtschlaf- und Tiefschlafphasen erkennen, das zum Auslösen eines Weckvorganges herangezogen werden kann.The present invention is based on the discovery that the movements of a person in sleep are associated with particular sleep phases. It has been found that at the beginning and at the end of certain sleep phases there is increased body movement, which makes it possible to differentiate between the individual sleep phases. If the movements are tracked during sleep, then a specific pattern of light sleep and deep sleep phases can be detected, which can be used to trigger a wake-up process.

Nach einer bevorzugten Ausführungsform wird von den registrierten Bewegungen des Schlafenden mittels eines Algorithmus auf dessen Schlafzustand geschlossen. Die Ermittlung des Algorithmus kann beispielsweise durch Speicherung der Bewegungen eines oder mehrerer Schlafzyklen bei deaktivierter Weckvorrichtung erfolgen. Die Verwendung eines Algorithmus zur Beurteilung des Schlafzustands bietet den Vorteil, dass sich Fehler durch zufällige Bewegungen, welche nicht den Beginn oder das Ende einer REM-Phase ankündigen, ausschalten lassen.According to a preferred embodiment of the registered movements of the sleeper is closed by means of an algorithm on its sleep state. The algorithm can be determined, for example, by storing the movements of one or more sleep cycles when the alarm device is deactivated. The use of an algorithm for assessing sleep state has the advantage that errors due to random movements, which do not announce the beginning or the end of a REM phase, can be switched off.

Zweckmäßig wird die Aktivierung der Weckvorrichtung in Abhängigkeit vom Schlafzustand vorgenommen, wobei der Weckvorgang während einer psychisch und physisch günstigen Schlafphase ausgelöst wird. Hierbei ist es besonders vorteilhaft, wenn die Aktivierung innerhalb einer Weckzeitvorgabe, wie innerhalb eines Zeitraums von einer halben Stunde, z.B. zwischen 5.45 und 6.15 Uhr, erfolgt, da es damit möglich wird, unabhängig von einem bestimmten, möglicherweise ungünstigen Zeitpunkt ein Erwachen der schlafenden Person herbeizuführen.The activation of the alarm device is expediently carried out as a function of the sleep state, the alarm being triggered during a psychologically and physically favorable sleep phase. It is particularly advantageous in this case if the activation within a wake-up time specification, such as within a period of half an hour, e.g. between 5.45 and 6.15, takes place, since it makes it possible to induce an awakening of the sleeping person independently of a certain, possibly unfavorable time.

Die Aktivierung der Weckvorrichtung erfolgt bevorzugt nach vorgebbaren Schlafzyklen von aufeinanderfolgenden Tiefschlaf- und Leichtschlafphasen. Bei vielen Menschen reicht eine bestimmte Anzahl von Tiefschlaf- und Leichtschlafphasen zur vollständigen Erholung aus. Die sonst unnötigerweise schlafend verbrachte Zeit nach den erforderlichen Schlafphasen kann mittels Wecken nach Vorgabe eines bestimmten Schlafzyklus sinnvoll genutzt werden.The activation of the wake-up device preferably takes place after predefinable sleep cycles of successive deep sleep and light sleep phases. In many people, a certain number of deep sleep and light sleep phases will suffice for complete recovery. The otherwise unnecessarily dormant time spent after the required sleep phases can be usefully used by waking up to the specification of a particular sleep cycle.

Das Wecken kann individuell verschieden mittels sensorischer, akustischer oder optischer Reize erfolgen.The awakening can be done individually differently by means of sensory, acoustic or optical stimuli.

Eine Weckeinrichtung zur Durchführung des oben beschriebenen Verfahrens, welche eine Weckvorrichtung und einen über Funk mit der Weckvorrichtung gekoppelten Bewegungssensor umfasst, wobei zur Funkkoppelung ein Sender und ein Empfänger vorgesehen sind, ist dadurch gekennzeichnet, dass der Sender und der Empfänger angeordnet sind, um erst durch Registrierung einer Bewegung zur Sendung bzw. zum Empfang aktiviert, zu werden.A wake-up device for carrying out the method described above, which comprises a wake-up device and a motion sensor coupled to the wake-up device by radio, wherein a transmitter and a receiver are provided for radio coupling, characterized in that the transmitter and the receiver are arranged to first through Registration of a movement to be sent or received to be activated.

In einer bevorzugten Ausführungsform ist der Bewegungssensor von einem Beschleunigungsmesser gebildet.In a preferred embodiment, the motion sensor is formed by an accelerometer.

In weiteren bevorzugten Ausführungsformen ist der Bewegungssensor als Ultraschall-, Infrarot- oder Mikrowellensensor ausgebildet.In further preferred embodiments, the motion sensor is designed as an ultrasound, infrared or microwave sensor.

Vorteilhaft ist der Bewegungssensor in Form einer Armbanduhr ausgebildet.Advantageously, the motion sensor is designed in the form of a wristwatch.

Die erfindungsgemäße Einrichtung umfaßt zweckmäßig eine Einstelleinrichtung zur Vorgabe einer Weckzeit und/oder von Schlafzyklen.The device according to the invention expediently comprises an adjustment device for presetting an alarm time and / or sleep cycles.

Vorzugsweise weist die Weckvorrichtung ein Läutwerk auf oder umfaßt eine Lichtaktivierungseinheit, die auf akustischem bzw. optischem Weg ein Erwachen der schlafenden Person herbeiführen, sobald der Weckvorgang eingeleitet wird.Preferably, the alarm device has a bell or comprises a light activation unit, which cause an awakening of the sleeping person acoustically or optically, as soon as the alarm is initiated.

Die Erfindung ist nachfolgend anhand der Zeichnung näher erläutert, wobei Fig. 1 ein Schlafphasendiagramm mit dazugehörigem Bewegungsmuster und Fig. 2 eine Ausführungsform der erfindungsgemäßen Weckeinrichtung in schematischer Darstellung veranschaulichen.The invention is explained in more detail with reference to the drawing, wherein Fig. 1 a sleep phase diagram with associated movement pattern and Fig. 2 an embodiment of the alarm device according to the invention in a schematic representation illustrate.

Fig. 1 zeigt ein durchschnittliches Schlafphasendiagramm, in welchem für eine Schlafdauer von etwa 8 Stunden (Abszisse) der Ablauf der einzelnen Schlafphasen und analog dazu das Bewegungsmuster graphisch dargestellt sind. Auf der ersten Ordinate sind der Wachzustand, der REM-Zustand sowie verschiedene Schlafstadien als Stufen von 1 bis 4 eingezeichnet, wobei die Tiefe des Schlafs von Stufe 1 bis Stufe 4 zunimmt. Auf der dem Bewegungsmuster zugeordneten Ordinate sind die zwei Zustände "Bewegungen" und "keine Bewegungen" angegeben. Fig. 1 shows an average sleep phase diagram in which for a sleep time of about 8 hours (abscissa) the sequence of the individual sleep phases and analogous to the movement pattern are shown graphically. On the first ordinate, wakefulness, the REM state, and various stages of sleep are plotted as levels 1 through 4, with the depth of sleep increasing from level 1 to level 4. The two states "movements" and "no movements" are indicated on the ordinate associated with the movement pattern.

Im Diagramm ist deutlich ein Abwechseln von Tiefschlaf- und Leichtschlafphasen (REM-Phasen) zu erkennen, wobei Dauer und Tiefe der Tiefschlafphasen mit zunehmender Schlafdauer abnehmen. Die Dauer der REM-Phasen hingegen nimmt gegen Schlafende zu.The diagram clearly shows a change of deep sleep and light sleep phases (REM phases), whereby the duration and depth of the deep sleep phases decrease with increasing sleep duration. The duration of the REM phases, however, increases towards the sleepers.

Das etwas vereinfachte und abstrahierte Bewegungsmuster (Einzelbewegungen sind nicht dargestellt) läßt erkennen, dass zu Beginn und am Ende der REM-Phasen gehäuft Bewegungen auftreten.The somewhat simplified and abstracted movement pattern (individual movements are not shown) indicates that frequent movements occur at the beginning and at the end of the REM phases.

Aufgrund dieses Zusammenhangs zwischen Bewegungen und REM-Phasen ist es möglich, die Bewegungen eines Menschen im Schlaf zum Wecken unter Berücksichtigung der Schlafphasen heranzuziehen, da relativ einfach ein günstiger Weckzeitpunkt ermittelbar ist.Because of this relationship between movements and REM phases, it is possible to use the movements of a person in sleep to wake up, taking into account the sleep phases, as relatively easy a favorable wake-up time can be determined.

So wird zum Beispiel bei einer Weckzeitvorgabe (Fig. 1: 7.00 bis 7.30 Uhr) mit Hilfe der registrierten Bewegungen ein für den Schlafenden günstiger Weckzeitpunkt oder -zeitraum Z, sofern ein solcher innerhalb der Weckzeitvorgabe vorhanden ist, eruiert, indem das Ende einer REM-Phase abgewartet oder mittels eines Algorithmus vorausberechnet wird. Ob der Weckvorgang zum ersten möglichen günstigen Zeitpunkt oder zum letztmöglichen ausgelöst werden soll, kann dabei beliebig gewählt werden.For example, with a wake-up time setting ( Fig. 1 : 7.00 to 7.30 o'clock) with the help of the registered movements, a sleep time or time period Z favorable for the sleeping person, if such exists within the alarm time setting, is determined by awaiting the end of a REM phase or precalculating by means of an algorithm. Whether the wake-up is to be triggered for the first possible favorable time or the last possible, can be chosen arbitrarily.

Ebenso ist es möglich, eine Aktivierung der Weckvorrichtung nach vorgebbaren Schlafzyklen mit einer bestimmten Anzahl von aufeinanderfolgenden Tiefschlaf- und Leichtschlafphasen vorzunehmen, indem die verstrichenen Schlafphasen mittels Registrierung der Bewegungen gezählt werden.It is also possible to make an activation of the wake-up device after predefinable sleep cycles with a certain number of consecutive deep sleep and light sleep phases by the elapsed sleep phases are counted by registering the movements.

Gemäß Fig. 2 umfaßt die erfindungsgemäße Einrichtung zum Wecken einen Bewegungssensor 1, der von einem Beschleunigungsmesser gebildet oder als Ultraschall-, Infrarot- oder Mikrowellensensor ausgebildet sein kann. Der Bewegungssensor 1 ist getrennt von einer Weckvorrichtung 2 angeordnet, wobei die Koppelung dieser Komponenten mittels einer Funkeinrichtung mit Sender 6 und Empfänger 7 erfolgt. Der Funkverkehr zwischen den beiden Teilen 6 und 7 wird erst bei Registrierung einer Bewegung durch den Bewegungssensor 1 aktiviert, so dass die Belastung durch Funkwellen für den Schlafenden gering ist. Der Bewegungssensor 1 ist hierbei vorteilhaft in Form einer Armbanduhr ausgebildet.According to Fig. 2 The inventive device for waking comprises a motion sensor 1, which may be formed by an accelerometer or designed as an ultrasonic, infrared or microwave sensor. The motion sensor 1 is arranged separately from a wake-up device 2, wherein the coupling of these components by means of a radio device with transmitter 6 and receiver 7 takes place. The radio communication between the two parts 6 and 7 is activated only upon registration of movement by the motion sensor 1, so that the burden of radio waves for the sleeper is low. The motion sensor 1 is advantageously designed in the form of a wristwatch.

Weiters umfaßt die erfindungsgemäße Einrichtung eine Echtzeiteinrichtung 4, wie eine Uhr, und eine Einstelleinrichtung 5 zur Vorgabe einer Weckzeit und/oder von Schlafzyklen, welche beide mit einer Verarbeitungseinheit 3 in Verbindung stehen.Furthermore, the device according to the invention comprises a real-time device 4, such as a clock, and an adjustment device 5 for specifying an alarm time and / or sleep cycles, which are both connected to a processing unit 3.

Wird nun vom Bewegungssensor 1 eine Bewegung des Schlafenden registriert, so wird der Verarbeitungseinheit 3 ein Signal übermittelt und von dieser entsprechend ihrer Arbeitsweise zur Feststellung des momentanen Schlafzustands verwertet. Bei Vorgabe einer Weckzeit ist es Aufgabe der Verarbeitungseinheit 3, die Zeit aus der Echtzeiteinrichtung 4 mit der Weckzeitvorgabe aus der Einstelleinrichtung 5 zu vergleichen und bei Übereinstimmung von Echtzeit und Weckzeitvorgabe in Abhängigkeit von der berechneten oder festgestellten Schlafphase den Weckvorgang durch Aktivieren der Weckvorrichtung 2 auszulösen. Bei Vorgabe eines bestimmten Schlafzyklus können die zeitabhängigen Komponenten 4 und 5 der Einrichtung entfallen.If a movement of the sleeping person is now registered by the motion sensor 1, the processing unit 3 is sent a signal and utilized by the latter in accordance with its mode of operation for determining the instantaneous sleep state. When setting an alarm time, it is the task of the processing unit 3 to compare the time from the real-time device 4 with the wake-up time setting from the setting device 5 and trigger the wake-up process by activating the wake-up device 2 in accordance with real time and alarm time depending on the calculated or detected sleep phase. When specifying a particular sleep cycle, the time-dependent components 4 and 5 of the device can be omitted.

Wie bei herkömmlichen Weckern kann die Weckvorrichtung 2 ein Läutwerk zum Auslösen akustischer Reize aufweisen, sie kann aber auch mit einer Lichtaktivierungseinheit ausgestattet sein, die ein Wecken mittels optischer Reize ermöglicht. Ist der Bewegungssensor 1 in Form einer Armbanduhr ausgebildet, wäre auch die Anwendung taktiler Reize, beispielsweise elektrisch erzeugter Hautreizung, denkbar.As with conventional alarm clocks, the alarm device 2 may have a bell to trigger audible stimuli, but it may also be equipped with a light activation unit that allows awakening by means of optical stimuli. If the motion sensor 1 is designed in the form of a wristwatch, the use of tactile stimuli, for example electrically generated skin irritation, would also be conceivable.
