Abstract (en)
A radio controlled clock includes a primary micro-control unit receiving radio signals, a mechanical analogue time display controlled by the primary micro-control unit to display time, a secondary micro-control unit receiving pulse signals from the primary micro-control unit, and a digital time display controlled by the secondary micro-control unit to display time. The clock further comprises a light emitter and photo-coupler associated with the mechanical analogue time display and the primary micro-control unit to transmit a zero signal to the secondary micro-control unit. <IMAGE>
