Description

Vorrichtung zum Erzeugen von elektronischen Signalen Device for generating electronic signals
Es ist an sich bekannt, dass der Mensch zur Erzeugung von Steuersignalen irgendwelcher Art seine Extremitäten gebraucht. Es sind auch schon Einrichtungen geschaffen worden, die dazu dienen, dass der Mensch mittels relativ schwacher Mundbewegungen, also zum Beispiel durch Saugen oder Blasen, elektrische Signale erzeugen und mit diesen dann irgendwelche Bewegungsabläufe steuern kann.It is known per se that humans use their extremities to generate control signals of any kind. Devices have also been created which serve to enable people to generate electrical signals by means of relatively weak mouth movements, for example by sucking or blowing, and then to use them to control any movement sequences.
Die vorliegende Erfindung betrifft nun ebenfalls eine Einrichtung zum Erzeugen elektrischer Signale. Sie ist jedoch dadurch gekennzeichnet dass sie ein Brillenge¬ stell mit mindestens einem durch die Kopfbewegung des Gestellträgers ein- und ausschaltbaren Quecksilberschal¬ ter und/oder mit mindestens einer durch eine Augenbraue oder ein Augenlid des Gestellträgers unterbrechbare Lichtschranke aufweist.The present invention now also relates to a device for generating electrical signals. However, it is characterized in that it has a spectacle frame with at least one mercury switch that can be switched on and off by the head movement of the frame carrier and / or with at least one light barrier that can be interrupted by an eyebrow or an eyelid of the frame carrier.
Vorzugsweise ist ein Quecksilberschalter so ausgebildet und angeordnet, dass beim Kippen des Gestells um eine von Scharnier zu Scharnier gehende Verbindungslinie oder um eine zu dieser Linie parallelen Achse der Schalter- Kontakt geöffnet oder geschlossen wird oder dass beim Kippen des Gestells um eine zu den geöffneten Gestell¬ stangen parallele Achse der Schalter-Kontakt geöffnet oder geschlossen wird.A mercury switch is preferably designed and arranged in such a way that when the frame is tilted about a connecting line going from hinge to hinge or about an axis parallel to this line, the switch contact is opened or closed, or that when the frame is tilted about one of the open frames ¬ rods parallel axis of the switch contact is opened or closed.
Der Strahlsender der Lichtschranke kann ein Infrarot¬ sender oder ein monochromatischer Strahlsender oder ein Impulsstrahlsender sein, wobei der Strahlempfänger eine dem Sender angepasste Empfindlichkeit aufzuweisen hat. Es ist auch möglich, mindestens den Strahlsender oder den Strahlempfänger mit einem Lichtleiter auszurüsten.The beam transmitter of the light barrier can be an infrared transmitter or a monochromatic beam transmitter or a Be pulse beam transmitter, the beam receiver having a sensitivity adapted to the transmitter. It is also possible to equip at least the beam transmitter or the beam receiver with a light guide.
Nachfolgend werden anhand der beiliegenden Zeichnung Ausführungsbeispiele der Erfindung beschrieben. In der Zeichnung zeigtExemplary embodiments of the invention are described below with reference to the accompanying drawing. In the drawing shows
die Figur 1 einen Horizontalschnitt durch eine1 shows a horizontal section through a
Brillenhälfte eines ersten Ausführungs¬ beispiels etwa im Bereich der Brillen¬ stangen und durch das zugehörige Augenlid desjenigen, der das Gestell ' trägt, undGlasses half of a first Ausführungs¬ example approximately in the range of Brillen¬ rods and that of by the associated eyelid, which carries the frame, 'and
die Figur 2 eine perspektivische Ansicht eines weitern Ausführungsbeispiels.FIG. 2 shows a perspective view of a further exemplary embodiment.
Das Brillengestell weist eine Fassung 1 für die Gläser 2 auf, von denen in der Zeichnung nur eines dargestellt ist. Für die vorliegende Erfindung ist es jedoch nicht nötig, dass das Gestell mit Gläsern versehen ist. Wenn der Gestellträger keine Brille benötigt, so kann er das Gestell ohne eingesetzte Gläser verwenden. An jeder der beiden Stangen 3, die je durch* ein Scharnier 7 mit der Gläserfassung 1 verbunden sind, ist ein Infrarot-Sender 4 befestigt, während die Fassung 1 die zugeordneten Strahlenempfänger 5 trägt. Die beiden elektronischen Bauelemente sind nun, wie man aus der Zeichnung ersehen kann, so angeordnet, dass die gerade Verbindungslinie 6 zwischen Sender und Empfänger durch den Bereich hin¬ durchgeht, der beim richtigen Tragen des Brillengestells vom Augenlid 8 oder der Wimper 9 überstrichen wird, wenn das zugehörige Auge geöffnet oder geschlossen wird. Eine nicht dargestellte, mit dem Empfänger 5 durch eine Leitung 5a verbundene elektronische Schaltanordnung dient dann dazu, die vom Empfänger 5 eintreffenden Steuerimpulse in elektronische Steuersignale zu verar- beiten, wobei diese Anordnung vorzugsweise so ausge¬ bildet ist, das beim gleichzeitigen Eintreffen von Impulsen aus beiden Empfängern, also dann, wenn die beiden Augenlider gemeinsam bewegt werden, kein Steuer¬ signal entsteht, während beim Eintreffen einzelner Impulse ein Signal entsteht. Dieses Signal kann ver¬ schieden sein, je nach dem, ob der Impuls nur vom rechten oder vom linken Augenlid ausgelöst worden ist oder ob einem Impuls von einem Augenlid innerhalb einer be¬ stimmten kurzen Frist ein vom andern Augenlid ausge- löster Impuls folgt, wobei auch hier durch entsprechende Ausgestaltung der Schaltanordnung z.B. die Möglichkeit besteht, das Signal je nach dem, von welchem Augenlid der erste Impuls kam, an einen bestimmten von mehreren Ausgängen der Schaltanordnung zu leiten. Auch kann die Schaltanordnung so ausgestaltet sein, dass für Doppel¬ bewegungen, Mehrfachbewegungen oder andere spezielle Bewegungen eines Lides oder für bestimmte Kombinationen von Augenlidbewegungen ein elektronisches Signal oder die elektronischen Signale an verschiedene Ausgänge gegeben. werden.The spectacle frame has a holder 1 for the glasses 2, of which only one is shown in the drawing. For the present invention, however, it is not necessary for the frame to be provided with glasses. If the rack holder does not need glasses, he can use the rack without glasses. At each of the two rods 3, which are each connected by a hinge 7 * with the lens frame 1, is mounted an infra-red transmitter 4, while the socket 1 5 carries the associated radiation receiver. The two electronic components are now, as can be seen from the drawing, arranged in such a way that the straight connecting line 6 between the transmitter and receiver passes through the area which is covered by the eyelid 8 or the eyelash 9 when the glasses frame is worn correctly. when the associated eye is opened or closed. An electronic switching arrangement (not shown), which is connected to the receiver 5 by a line 5a, then serves to process the control pulses arriving from the receiver 5 into electronic control signals, this arrangement preferably being designed so that when pulses arrive at the same time In both receivers, that is to say when the two eyelids are moved together, no control signal is produced, while a signal is generated when individual pulses arrive. This signal can be different, depending on whether the pulse was triggered only by the right or left eyelid or whether a pulse triggered by one eyelid is followed by a pulse triggered by the other eyelid within a certain short period of time, whereby here too, by means of a corresponding configuration of the switching arrangement, it is possible, for example, to route the signal to a specific one of several outputs of the switching arrangement depending on the eyelid from which the first pulse came. The switching arrangement can also be designed such that an electronic signal or the electronic signals are given to different outputs for double movements, multiple movements or other special movements of a lid or for certain combinations of eyelid movements. become.
Mit einer derartigen Anordnung lassen sich dann ver¬ schiedene Funktionen steuern, so dass nicht nur Para- plegiker sondern auch Tretraplegiker die Möglichkeit haben, Bewegungen auszulösen, wie zum Beispiel die Verstellung ihres Liegebettes oder den Motor Ihres Rollstuhles zu steuern oder das Fernsehgerät oder andere Apparate zu bedienen. Selbstverständlich kann man zur Vermeidung von Störungen einen Strahlsender verwenden der monochromatisch oder gepulstes Licht erzeugt, wobei dieses Licht nicht unbedingt infrarot sein muss. Es ist dann nur nötig, dass man einen Empfänger mit einer dem Sender angepasste Empfindlichkeit verwendet.Such an arrangement can then be used to control various functions, so that not only paraplegics but also quadriplegics have the possibility of triggering movements, such as controlling the adjustment of their bed or the motor of their wheelchair or the television or other apparatus to use. To avoid interference, it is of course possible to use a beam transmitter which generates monochromatic or pulsed light, this light not necessarily having to be infrared. It is then only necessary to use a receiver with a sensitivity adapted to the transmitter.
Bei dem in der Figur 2 dargestellten Ausführungsbeispiel besteht das Brillengestell ebenfalls aus einer Fassung 1 für die Gläser, an welcher mittels je eines Scharniers 7 die beiden Stangen 3 angelenkt sind, wobei das Gestell im geöffneten Zustand dargestellt ist, also so, wie man es benutzt. An den beiden Stangen 3 ist je ein Quecksil¬ berschalter 10 bzw. 11 angebracht, wobei diese Schalter so ausgebildet und angeordnet sind, dass beim Kippen des Gestells um die von Scharnier zu Scharnier 7 gehende Verbindungslinie 12 oder um eine zu dieser Linie paral¬ lele Achse der Schalterkontakt der Schalter geöffnet oder geschlossen wird. Bei der Verwendung von zwei Quecksilberschaltern wird es zweckmässig sein, wenn man die Schalter so anordnet, dass sie nicht gleichzeitig sondern bei etwas verschiedenen Neigungswinkeln den Schaltvorgang auslösen, damit der Träger des Brillenge¬ stells je nach der Grosse des Neigungswinkels die Möglichkeit hat, verschiedene Signale auszulösen. Man kann die Schalter beispielsweise so anordnen, dass bei vertikaler Glasebene keiner der Schalter geschlossen ist und dass beim Anheben des Kopfes aus dieser Stellung der eine Schalter, bei Senken des Kopfes aus dieser Stellung der andere Schalter schliesst. Alle Schalter sind selbstverständlich durch Leitungsdrähte mit einer nicht gezeichneten Schaltanordnung verbunden, wobei die Leitungsdrähte in den Stangen des Brillengestells integriert oder an diesen befestigt sein können. Wie man aus der Zeichnung ersehen kann, können die Schalter an sich irgendwo an den Stangen angebracht sein, wichtig ist nur, dass sie den Träger des Gestells nicht stören. Zusätzlich zu diesen Schaltern 10 und 11 oder anstelle dieser Schalter ist es auch möglich, einen oder mehrere Quecksilberschalter 13 und 14 so anzuordnen, dass beim Kippen des Gestells um eine zu den geöffneten Gestell¬ stangen 3 parallele Achse der Schaltkontakt geöffnet oder geschlossen wird. Auch bei diesen Schaltern sind verschiedene Anordnungen möglich: Man kann z.B. die Schalter so befestigen, dass dann, wenn sich beide Augen in gleicher Höhe befinden, die beiden Schalter ausge¬ schaltet sind, und dass derjenige Schalter, der gegen¬ über dem andern angehoben wird, geschlossen wird.In the embodiment shown in Figure 2, the eyeglass frame also consists of a holder 1 for the glasses, to which the two rods 3 are hinged by means of a hinge 7, the frame being shown in the open state, that is to say as it is used . A mercury switch 10 or 11 is attached to each of the two rods 3, these switches being designed and arranged such that when the frame is tilted around the connecting line 12 going from hinge to hinge 7 or around a line parallel to this line Axis of the switch contact the switch is opened or closed. When using two mercury switches, it will be expedient if the switches are arranged in such a way that they trigger the switching process not at the same time but at somewhat different angles of inclination, so that the wearer of the spectacle frame, depending on the size of the angle of inclination, has the possibility of different signals trigger. The switches can be arranged, for example, in such a way that none of the switches is closed when the glass plane is vertical and that one switch closes when the head is raised from this position and the other switch closes from this position when the head is lowered. All switches are of course connected by lead wires to a switching arrangement, not shown, wherein the lead wires can be integrated in the rods of the spectacle frame or attached to them. As you can see from the drawing, the switches can be turned on attached to the poles somewhere, the only thing that is important is that they do not interfere with the support of the frame. In addition to these switches 10 and 11 or instead of these switches, it is also possible to arrange one or more mercury switches 13 and 14 in such a way that when the frame is tilted about an axis parallel to the open frame rods 3, the switch contact is opened or closed. Various arrangements are also possible with these switches: for example, the switches can be fastened in such a way that when both eyes are at the same height, the two switches are switched off, and the switch that is raised relative to the other , is closed.
Im einfachsten Fall einer Schaltanordnung kann man z.B. einen vor- oder rückwärts verfahrbaren, nach rechts oder links steuerbaren Rollstuhl wie folgt bedienen:In the simplest case of a switching arrangement, one can e.g. operate a wheelchair that can be moved forwards or backwards and steered to the right or left as follows:
Bei geöffneten Schaltern steht der Rollstuhl still. Solange der Schalter 10 durch Anheben des Kopfes ge¬ schlossen ist, so fährt der Rollstuhl vorwärts, wird aber der Schalter 11 durch Neigen des Kopfes ge¬ schlossen, so fährt der Stuhl rückwärts. Wenn durch Neigen des Kopfes nach rechts der Schalter 13 ge- schlössen wird, werden die lenkbaren Räder nacht rechts verschwenkt, während bei einer Kopfneigung nach links das Schliessen des Schalters 14 ein Verschwenken der Steuerräder nach links verursacht.The wheelchair stands still when the switches are open. As long as the switch 10 is closed by lifting the head, the wheelchair moves forward, but if the switch 11 is closed by tilting the head, the chair moves backwards. If the switch 13 is closed by tilting the head to the right, the steerable wheels are pivoted to the right, while if the head is tilted to the left, the switch 14 causes the steering wheels to pivot to the left.
Selbstverständlich lässt sich ein Brillengestell gleich¬ zeitig mit den anhand der Figur 1 und den anhand der Figur 2 beschriebenen Schaltelementen ausrüsten, so dass dem Träger sehr viele Möglichkeiten und Kombinationsmög¬ lichkeiten zum Erzeugen von verschiedenen elektronischen Signalen zur Verfügung stehen.Of course, an eyeglass frame can be equipped at the same time with the switching elements described with reference to FIG. 1 and with the aid of FIG. 2, so that the wearer has a great number of possibilities and combination possibilities for generating different electronic signals.
