According to the invention, the method comprises the following procedural steps: - detecting the movements of a person with the generation of signals, - working out the signals such that they are matched to a timer; - comparison of the generated signals in the timer, - transmission of the signals to a display installation when signals are present which deviate from preset values. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf eine Methode zur Erfassung von diskontinuierlichen, unregelmäßigen Bewegungen einer Person, gemäß dem Oberbegriff des Anspruches 1 und eine Anlage für deren Durchführung, gemäß dem Oberbegriff des Anspruches 5.
Es ist bekannt, ungewohnte Bewegungen, beispielsweise eines Autofahrers zu erfassen, wenn diese Bewegungen ein nicht mehr kontrollierbares Verhalten seitens des Autofahrers mit Verminderung seiner Aufmerksamkeit am Autosteuer anzeigen könnten: Dies könnte z.B. geschehen, wenn bei einem Schlafanfall der Kopf des Autofahrers ruckartig nach vorne gebeugt wird. So bestehen zur Zeit Vorrichtungen, die am Kinn des Autofahrers angebracht werden, um diese ruckartige Bewegungen einer Alarmanlage beispielsweise mit akustischem Alarm anzuzeigen. Es ist zu bemerken, daß Vorrichtungen dieser Art, z.B. auch bei einer Bremsung des Fahrzeuges in Funktion treten, sodaß die Alarmanlage vergebens betätigt wird, obwohl der Autofahrer selbst noch voll imstande ist, das Fahrzeug zu beherrschen.The present invention relates to a method for detecting discontinuous, irregular movements of a person, according to the preamble of claim 1, and a system for carrying them out, according to the preamble of claim 5.
It is known to detect unusual movements, for example of a motorist, if these movements could indicate behavior that the motorist is no longer able to control and reduce his or her attention to the car control: This could happen, for example, if the motorist's head was jerked forward during a sleep attack becomes. There are currently devices that are attached to the chin of the driver to indicate these jerky movements of an alarm system, for example with an acoustic alarm. It should be noted that devices of this type, for example, also operate when the vehicle brakes, so that the alarm system is activated in vain, although the driver himself is still fully able to control the vehicle.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, dieses Problem zu lösen und eine Methode vorzuschlagen, die dazu ausgelegt ist, den Mangel an Aufmerksamkeit nur in kritischen Situationen, wie bei Schlafgefahr anzuzeigen. Überdies soll eine Anlage zur Durchführung der Methode selbst vorgeschlagen werden.The object of the present invention is therefore to solve this problem and to propose a method which is designed to indicate the lack of attention only in critical situations, such as when there is a danger of sleeping. In addition, an installation for implementing the method itself is to be proposed.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1, was die Methode betrifft, und durch die Merkmale des kennzeichnenden Teils des Anspruchs 5, was die Anlage betrifft gelöst.This object is achieved by the features of the characterizing part of claim 1, which relates to the method, and by the features of the characterizing part of claim 5, which relates to the system.

Durch Erfassung von charakteristischen Bewegungen, die von jenen persönlichen, normalen einer Person abweichen, wie beispielsweise der Wimpernschlag bzw. der Liderschlag, und durch Vergleich einer bestimmten Anzahl von Bwegegungen wie Wimpernschlägen bzw. Liderschlägen mit einer Standardanzahl von normalen Bewegungen können durch einen Timer Signale an eine Alarmanlage gesandt werden.By detecting characteristic movements that deviate from a person's personal, normal movements, such as the blinking of an eye or eyelash, and by comparing a certain number of movements such as eyelashes or blinking with a standard number of normal movements, signals can be triggered by a timer an alarm system can be sent.

Weitere Ausbildungen und Varianten der erfindungsgemäßen Methode und Anlage gehen aus den abhängigen Ansprüchen hervor.Further designs and variants of the method and system according to the invention emerge from the dependent claims.

Wie Figur 1 zeigt, umfaßt eine Anlage einen Fühler 1, beispielsweise bekannter Art mit infraroter Strahlung mit oder ohne Reflektion, mit Ultraschall oder anderer Art, um Bewegungen auf Distanz zu erfassen. Der Fühler 1 ist durch eine elektrische Leitung 2 mit einem Signalverstärker 3 verbunden, dem vorzugsweise eine aufladbare Batterie 4, beispielsweise eine Solarzellenbatterie oder eine von Solarzellen speisbare Batterie zugeordnet ist. Der Verstärker 3 ist über eine elektrische Leitung 5 mit einem Timer 6 verbunden. Der Timer 6 vergleicht den Verlauf der Ist-Signale mit dem Verlauf von Soll-Signalen, die gemäß den Merkmalen des normalen Verhaltens einer Person voreingestellt sind. Der Timer 6 ist seinerseits über eine elektrische Leitung 7 mit einer Alarmanlage 8 verbunden, die akustischer, visueller oder anderer geeigneter Art sein kann. Alle Bestandteile sind in dieser ersten Ausführungsform in einer gestrichelt angegebenen Aufnahme 9 aufgenommen, die ihrerseits bevorzugt in einem der nicht gezeigten Bügel von Brillen aufgenommen ist, die z.B. vom Autofahrer getragen werden.As FIG. 1 shows, a system comprises a sensor 1, for example of a known type with infrared radiation with or without reflection, with ultrasound or another type, in order to detect movements at a distance. Sensor 1 is connected by an electrical line 2 to a signal amplifier 3, which is preferably associated with a rechargeable battery 4, for example a solar cell battery or a battery that can be fed by solar cells. The amplifier 3 is connected to a timer 6 via an electrical line 5. The timer 6 compares the course of the actual signals with the course of target signals, which are preset according to the characteristics of the normal behavior of a person. The timer 6 is in turn connected via an electrical line 7 to an alarm system 8, which can be of an acoustic, visual or other suitable type. In this first embodiment, all components are accommodated in a receptacle 9 indicated by dashed lines, which in turn is preferably accommodated in one of the brackets (not shown) of glasses which are worn, for example, by the driver.

Wird somit im Timer 6 ein Zeitverlauf der Signale festgestellt, die vom normalen Verlauf abweichen, gibt der Timer 6 selbst Signale an die Anlage 8 für deren Einschaltung ab.If a time course of the signals which deviate from the normal course is determined in the timer 6, the timer 6 itself emits signals to the system 8 for its activation.

In Figur 2 ist hingegen eine Anlage dargestellt, die ebenfalls einen Fühler 10 aufweist, der dem Fühler 1 der ersten Ausführungsform entspricht, d.h. über eine elektrische Leitung 11 mit einem Verstärker 12 verbunden ist, dem eine beispielsweise durch Solarzellen aufladbare Batterie 13 zugeordnet ist. Der Verstärker ist über eine elektrische Leitung 14 mit einem Kodiergerät 15 verbunden, der die empfangenen Signale kodiert, um sie an einem Sender 16 anzupassen, um die Signale über Funk 17 einem Empfänger 18 zu senden. Dieser ist über eine elektrische Leitung 19 mit einem Dekoder 20 verbunden, der die Signale einem veränderbaren Timer 21 sendet. Dieser ist über eine elektrische Leitung 22 mit einer Alarmanlage 23 akustischer oder visueller, bekannter Art verbunden. Die Bestandteile 10, 12, 16 und 17 sind bevorzugt in einer mit 24 bezeichneten Aufnahme aufgenommen, die beispielsweise an einem vom Benützer zu tragenden, nicht gezeigten Brillengestell anzuordnen ist. Die Bestandteile 18, 20, 21 und 23 sind hingegen in einer mit 25 angedeuteten Aufnahme aufgenommen, die z.B. am Armaturenbrett eines Fahrzeugs angebracht ist. Die Ausführung von Systemen mit Passivfühlern ist somit möglich.In contrast, FIG. 2 shows a system which likewise has a sensor 10 which corresponds to sensor 1 of the first embodiment, ie is connected via an electrical line 11 to an amplifier 12 to which a battery 13, for example chargeable by solar cells, is assigned. The amplifier is connected via an electrical line 14 to a coding device 15, which codes the received signals in order to adapt them to a transmitter 16 in order to transmit the signals via radio 17 to a receiver 18. This is connected via an electrical line 19 to a decoder 20 which receives the signals sends a changeable timer 21. This is connected via an electrical line 22 to an alarm system 23 of an acoustic or visual, known type. The components 10, 12, 16 and 17 are preferably accommodated in a receptacle denoted by 24, which is to be arranged, for example, on an eyeglass frame, not shown, to be worn by the user. The components 18, 20, 21 and 23, on the other hand, are received in a receptacle indicated by 25, which is attached, for example, to the dashboard of a vehicle. Systems with passive sensors are therefore possible.

In einer dritten Ausführungsform ist der Fühler 25 schließlich in einer Aufnahme 26 eines nicht gezeigten Brillengestells aufgenommen. Es kann sich dabei um einen reflektierenden Ultrarotstrahlenfühler, wie mit 27 angegeben, oder um einen Ultraschallfühler usw. handeln. Der Fühler 27 ist über eine Leitung 28 mit einem Verstärker 29 verbunden, dem eine aufladbare Batterie 30 zugeorndet ist. Der Verstärker 29 ist überdies mit einem Timer 31 verbunden, der seinerseits mit einer Alarmanlage 23, akustischer, visueller oder jeglicher anderer, bekannter Art verbunden ist. Die Bestandteile 29, 30, 31 und 32 sind in einer Aufnahme 23 aufgenommen, die auf einem Aufbau beispielsweise an den Enden der Brillenbügel oder von anderen Aufbauten angebracht ist, die mit dem Fühler verbindbar sind.In a third embodiment, the sensor 25 is finally received in a receptacle 26 of an eyeglass frame, not shown. It can be a reflective ultraviolet ray sensor, as indicated at 27, or an ultrasound sensor, etc. The sensor 27 is connected via a line 28 to an amplifier 29 to which a rechargeable battery 30 is assigned. The amplifier 29 is also connected to a timer 31, which in turn is connected to an alarm system 23, acoustic, visual or any other known type. The components 29, 30, 31 and 32 are accommodated in a receptacle 23 which is attached to a structure, for example at the ends of the eyeglass temples or from other structures which can be connected to the sensor.

Weitere Ausführungsformen und Varianten können vorgesehen sein, ohne den Schutzbereich der vorliegenden Erfindung zu verlassen. So kann der Fühler ein Aufnehmer jeglicher Art sein, der imstande ist, Änderungen des Zustandes eines Körpers zu erfassen, wie auch der Timer mit einem beliebigen Gatter versehen sein kann, das nur eine bestimmte Art von Signalen durchläßt, die vom Verlauf der voreingestellten Signale abweichen. Der Timer selbst kann gemäß dem Verhalten der Person, die die erfindungsgemäße Anlage benützt, eingestellt werden.Further embodiments and variants can be provided without leaving the scope of protection of the present invention. So the sensor can be a sensor of any kind that is able to detect changes in the state of a body, as can the timer with one can be provided any gate that only allows a certain type of signals that differ from the course of the preset signals. The timer itself can be set according to the behavior of the person using the system according to the invention.

Die Anlage selbst kann insgesamt auf einem beliebigen Gegenstand angebracht werden, der von einer Person getragen wird oder an einer festen Stelle mit Abstand von derselben derart angeordnet werden, daß der Aufnehmer imstande ist, die charakteristischen Merkmale zu erfassen. Die Bestandteile der Anlage können auch zwischen einem Benützer und einem festen Aufbau aufgeteilt werden.The system itself can be mounted on any object that is carried by a person or at a fixed location at a distance from it in such a way that the sensor is able to detect the characteristic features. The components of the system can also be divided between a user and a fixed structure.
