Description
Die vorliegende Erfindung betrifft eine Analog-Uhr, insbesondere Armbanduhr, mit Uhr-, Zeiger- und motorischen Antriebsmitteln sowie mit zusätzlich im Uhrengehäuse angeordneten Mitteln zum Messen und Anzeigen insbesondere atomarer Strahlungen.The present invention relates to an analog clock, in particular a wristwatch, with clock, pointer and motor drive means and with means additionally arranged in the watch case for measuring and displaying, in particular, atomic radiation.
Durch die US-A-4 733 383, welche eine Digital-Uhr mit Dosimeter-Schaltung zum Gegenstand hat, ist bereits angedeutet, dass auch eine Analog-Uhr mit der beschriebenen Dosimeter-Schaltung ausgestattet werden kann, wobei dort dann eine der Zeitimpulsfrequenzen der Dosimeter-Schaltung einen Schrittmotor für die Zeiger der Analog-Uhr antreibt.US-A-4,733,383, which relates to a digital watch with a dosimeter circuit, has already indicated that an analog watch can also be equipped with the described dosimeter circuit, one of the time pulse frequencies then being shown there Dosimeter circuit drives a stepper motor for the hands of the analog clock.
Alle Bauteile der Dosimeter-Schaltung sind dabei auf einem flachen Träger angeordnet. Wie hingegen das Kaliber der Analog-Uhr im Gehäuse untergebracht sein soll, ist nicht erkenntlich.All components of the dosimeter circuit are arranged on a flat carrier. However, it is not clear how the caliber of the analog watch should be housed in the case.
Da weder die betreffende Digital-Uhr noch die Analog-Uhr je auf dem Markt erschienen sind, ist anzunehmen, dass solche Uhren in der Entwicklung stecken geblieben sind, nachdem es offensichtlich bisher nicht gelungen ist, die umfängliche Elektronik und Mechanik in einem Armbanduhr-Gehäuse unterzubringen.Since neither the relevant digital watch nor the analog watch have ever appeared on the market, it can be assumed that such watches have got stuck in development after the extensive electronics and mechanics in a wristwatch case have apparently not yet succeeded to accommodate.
Obwohl lange vor der genannten US-Patentschrift durch die JP-A-56 031 684 biegsame Träger für die Schaltungsmittel von Digital-Uhren bekannt waren, hat das bisher zu keiner brauchbaren Lösung geführt.Although flexible supports for the switching means of digital clocks were known long before the said US patent by JP-A-56 031 684, this has so far not led to a usable solution.
Nachdem zudem inzwischen Digital-Uhren nicht mehr sehr marktgängig sind und Analog-Uhren wieder erheblich an Bedeutung gewonnen haben, ist es nun Aufgabe der vorliegenden Erfindung, eine Analog-Uhr, insbesondere Armbanduhr zu schaffen, die neben den üblichen Zeitgeberfunktionen in der Lage ist, eine atomare Einstrahlung exakt zu messen und anzuzeigen.In addition, since digital clocks are no longer very marketable and analog clocks have become significantly more important, it is the object of the present invention to create an analog clock, in particular a wristwatch, which, in addition to the usual timer functions, is capable of precisely measure and display atomic radiation.
Dies wird erfindungsgemäss zunächst dadurch erreicht, dass die Mittel zum Messen und Anzeigen der Strahlungen einen, in das Uhrengehäuse eingefalteten, biegefähigen, in der Abwicklung flächigen Schaltungsträger mit gedruckten Leiterbahnen umfassen, die einen Messfühler über eine Verstärkerund Auswertschaltung mit den Anzeigemitteln verbindet, wobei der eingefaltete, biegefähige Schaltungsträger eine erste, das Uhrwerk tragende Zwischenplatte durch Umbiegen von in der Abwicklung des Schaltungsträgers abragende Flächenteile umschliesst und mit einem weiteren Flächenteil eine zweite, die Primär-Batterie für den Uhrenantrieb tragende Zwischenplatte untergreift und wobei die Schaltungsmittel auf dem Schaltungsträger die Primär-Batterie sowie eine der Datensicherung dienende Sekundär-Batterie mit der Verstärker- und Auswertschaltung verbinden.According to the invention, this is first achieved by the fact that the means for measuring and displaying the radiation comprise a circuit board with flexible printed circuit traces, which is folded into the watch case and which is flat in the development, and which connects a measuring sensor to the display means via an amplifier and evaluation circuit, the folded one , Bendable circuit carrier encloses a first intermediate plate carrying the clockwork by bending surface parts protruding in the development of the circuit carrier and with a further surface part engages under a second intermediate plate carrying the primary battery for the clock drive, and wherein the switching means on the circuit carrier the primary battery and connect a secondary battery used for data backup to the amplifier and evaluation circuit.
Durch das geeignete Einfalten eines erfindungsgemäss biegefähigen Schaltungsträgers ist es nunmehr möglich, neben Uhren-Kaliber und Uhren-Batterie auch die umfangreichen Schaltungsmittel incl. Messfühler und Verstärker- und Auswertschaltung eines Dosimeters im Uhrengehäuse unterzubringen.By suitably folding in a circuit carrier that is flexible according to the invention, it is now possible to accommodate the extensive switching means including the measuring sensor and amplifier and evaluation circuit of a dosimeter in the watch case in addition to the watch caliber and watch battery.
Weiter ergibt sich eine kompakte Bauweise dadurch, dass eine der Zwischenplatten eine Abragung zur Abstützung des Messfühlers aufweist, der von einer Ausweitung des Uhrengehäuses umgeben ist.Furthermore, a compact design results from the fact that one of the intermediate plates protrudes to support the Has sensor, which is surrounded by an expansion of the watch case.
Von Vorteil ist zudem, dass die Sekundär-Batterie zur Datensicherung über die Verstärker- und Auswertschaltung geschaltet ist und mit einem Detektor zusammenwirkt, um einen Spannungsabfall an der Primär-Batterie der Uhr festzustellen und anzuzeigen, resp. eine automatische Umschaltung von der Primär-Batterie auf die Sekundär-Batterie vorzunehmen.It is also advantageous that the secondary battery for data backup via the amplifier and evaluation circuit is connected and cooperates with a detector to determine and display a voltage drop on the primary battery of the watch, respectively. perform an automatic switchover from the primary battery to the secondary battery.
Hierbei können die Mittel zum Messen und Anzeigen der Strahlungen an eine externe Computer-Prüf- und Auswertschaltung anschliessbar und die Mittel zum Anzeigen der Strahlung LCD-Displays sein. Weiter können die Mittel zur Anzeige der Strahlung ein zusätzliches Zeigerwerk umfassen.The means for measuring and displaying the radiation can be connected to an external computer test and evaluation circuit and the means for displaying the radiation can be LCD displays. The means for displaying the radiation can further comprise an additional pointer mechanism.
Von Vorteil ist ferner eine Verbindung zwischen dem Motor des Uhrwerkes und der Dosimeter-Zeitbasis des Multiprozessors, um genaue Zeit-Messwerte zu gewährleisten.A connection between the motor of the clockwork and the dosimeter time base of the multiprocessor is also advantageous in order to ensure accurate time measurement values.

Das Problem der Unterbringung der Schaltungsmittel für ein Dosimeter zum Messen und Anzeigen von Alpha-, Beta- oder Gamma-Strahlen ist nun gemäss der Darstellung in Fig. 2 dadurch gelöst, dass sich die Leiterbahnen und Schaltungsmittel auf einem in das Gehäuse der Uhr (hier nicht gezeigt) eingefalteten, biegefähigen, in der Abwicklung flächigen Schaltungsträger 2 befinden.The problem of accommodating the circuit means for a dosimeter for measuring and displaying alpha, beta or gamma rays is now solved according to the illustration in FIG. 2 in that the conductor tracks and circuit means are located on a foldable,

Die auf dem Silizium des Fühlers 3 auftreffende Gammastrahlung o. dgl. erzeugt Ladungsverschiebungen, welche das am Widerstand anliegende elektrische Potential derart verändern, dass am Gate eine Spannung entsteht, welche den durch weitere Widerstände (nicht gezeigt) eingestellten Ruhestrom verändert und elektrische Impulse generiert. Diese Impulse gelangen dann über die Verstärker- und Auswertschaltung 4 zur Anzeige an den LCD-Displays 16 und 17.Dosimeter circuits are known per se.

Wie Fig. 3 zudem zeigt, besteht ein weiteres vorteilhaftes Merkmal in der Verbindung zwischen dem Motor des Uhrwerkes 5 und der Dosimeter-Zeitbasis des Multiprozessors 4, um genaue Zeit-Messwerte zu gewährleisten.As FIG. 3 also shows, a further advantageous feature is the connection between the motor of the
