Abstract

An electronic timepiece, used as a pager watch, has a speaker for emitting an alarm sound at a preset time and also for reproducing an external call signal intercepted by a receiver for incoming electromagnetic waves. The receiver may be maintained normally inactive, being periodically activated for short time intervals under the control of a frequency divider in the output of a crystal oscillator serving to drive an electro-optical display. Sensors responsive to abnormal ambient conditions, e.g. temperature or blood pressure of the wearer, may also operate the speaker.

Claims

1. In a portable electronic timepiece, in combination:

a crystal oscillator;

frequency-dividing means connected to said oscillator;

counting means stepped by said frequency-dividing means;

code-conversion means connected to said counting means for generating time-indicating signals;

electro-optical display means connected to said code-conversion means for energization by said time-indicating signals in a display recurrent cycle of at least 12 hours;

normally deactivated receiving means for external signals;

timing means controlled by said frequency-dividing means for periodically activating said receiving means several times during said display cycle for a limited time interval; and

sound-emitting means responsive to external call signals upon activation of said receiving means by said timing means.

2. The combination defined in claim 1, further comprising resetting means for said counting means responsive to an external synchronizing signal from said receiving means.

3. The combination defined in claim 1, further comprising sensing means connected by way of said receiving means to said sound-emitting means for operating same upon detecting an abnormal ambient condition.
