Abstract

Eine autonome Funkuhr (11) mit Anzeige einer Information über die Empfangsgegebenheiten soll dem Konsumenten eine größere Sicherheit hinsichtlich der Korrektheit der momentanen Zeitanzeige (19) ver­ schaffen. Dafür ist ein - analoges oder digitales, gegebenenfalls mehrstellig-digitales Anzeigeelement (16) vorgesehen, das eine Zusatz­ information über die Empfangsqualität darbietet, ausgedrückt als Aussage über die Zeitspanne, die seit der jüngsten Überprüfung und gegebenenfalls Korrektur der Zeitanzeige (19) aufgrund einer über Funk empfangenen und dekodierten Zeitinformation (10) verstrichen ist. Wenn das Anzeigeelement (16) im Takte der Einschaltung des Empfängers (12) hochgezählt wird, bietet es stets die niedrigst­ mögliche Anzeige dar, wenn die Funkempfangsgegebenheiten so gut sind, daß jede Empfänger-Einschaltung zum Gewinnen einer verwertbaren Zeitinformation (10) führt. Diese Gewißheit über die Aktualität der Zeitanzeige (19) prädestiniert die Uhr (11) insbesondere zur Auslegung als Weckeruhr, die dann nur noch mit Stellelementen zur Alarmzeit-Vorgabe und Alarmunterbrechung oder -abschaltung ausgestattet zu sein braucht, bzw. gegebenenfalls zur Umschaltung einer Zusatzan­ zeige (22) zwischen dem vorgegebenen Alarmzeitpunkt und einer aus der Funkinformation (10) bzw. dem autonomen Betrieb der Uhr (11) gewonnenen Datumsinformation. An autonomous radio clock (11) with information about the Reception conditions are intended to provide consumers with greater security ver with regard to the correctness of the current time display (19) create. There is an - analog or digital, if necessary Multi-digit digital display element (16) provided that an addition provides information about the reception quality, expressed as Statement about the amount of time since the recent review and if necessary, correct the time display (19) due to an over Time information (10) received and decoded by radio passed is. If the display element (16) in time with the activation of the Receiver (12) is counted up, it always offers the lowest possible display if the radio reception conditions are so good are that each receiver engagement to gain a usable Time information (10) leads. This certainty about timeliness the time display (19) predestines the clock (11) especially for Design as an alarm clock, which then only with control elements Alarm time specification and alarm interruption or shutdown needs to be, or if necessary to switch an additional show (22) between the given alarm time and one the radio information (10) or the autonomous operation of the clock (11) obtained date information.
