METHOD FOR ENERGY CONSERVATION; DEVICE WHICH CORRECTS READINGS OF TIME SCALES USING EXTERNAL PRECISE TIME SIGNALS; CLOCK WITH AUTOMATIC CORRECTION OF READINGS USING PRECISE TIME SIGNALS Russian patent published in 1997 - IPC

FIELD: power production, clock industry. SUBSTANCE: periods of productive or other activity of person are placed into day-time period using clock which provides advance of zone time for season with maximal day-time duration. Said advance of zone time is achieved by its step-by-step increase up to maximal value for this concrete zone and following step-by-step decrease. Corresponding device has clock 13 with time scale generator, which has controlled channel for output of acoustic channel with output 16. Reading correction input 14 is connected to time-signal selector 18, which is included in external signal receiver 17 which has acoustic receiving-transmitting antenna 19 which is connected to input of external signal receiver 17 and output 16 through decoupling device which has commutator 20 and detector 21. EFFECT: increased functional capabilities. 7 cl, 3 dwg
