Abstract
Abstract The electronic timepiece comprises circuits within an integrated circuit for effecting at least one auxiliary function associated with information supplied to their inputs and, programming circuits for programming and memorizing the said information. A system applied to the timepiece makes it possible to consult and reprogram manually the memory from outside the timepiece, as well as memorizing the state of this memory in the absence of feed voltage, for as long as necessary.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
An electronic timepiece comprising: a power source; means for producing time base pulses of a first frequency; time display hands including a seconds hand; means connected to said power source for driving said time display hands in response to said time pulses for indicating the actual time; means responsive to said time base pulses for producing an actual time data signal; manually actuatable means for producing a data signal; means for performing an auxiliary function in response to said data signal; means for storing said data signal; means for producing on and off control signals; and control means having means responsive to said on control signal for coupling said stored data signal with said driving means for causing said driving means to drive said seconds hand to an indicating position corresponding to said stored data signal, said control means further having means responsive to said off control signal for uncoupling said stored data signal and for applying pulses to said means until said time display hands indicate the actual time.
Claim 2
Dependent Claim
170 words
An electronic timepiece comprising: a power source; means for producing time base pulses of a first frequency; time display hands including a seconds hand; means connected to said power source for driving said time display hands in response to said time pulses for indicating the actual time; means responsive to said time base pulses for producing an actual time data signal; manually actuatable means for producing a data signal; means for performing an auxiliary function in response to said data signal; means for storing said data signal; means for producing on and off control signals; and control means having means responsive to said on control signal for coupling said stored data signal with said driving means for causing said driving means to drive said seconds hand to an indicating position corresponding to said stored data signal, said control means further having means responsive to said off control signal for uncoupling said stored data signal and for applying pulses to said means until said time display hands indicate the actual time.
Claim 3
Dependent Claim
75 words
The electronic timepiece of claim 1, wherein said storing means includes manually actuatable means for producing a setting signal and manually actuatable means for producing a storing control signal; said control means further including means responsive to said setting signal for causing said driving means to drive said seconds hand to a desired position and means responsive to said storing control signal for causing the storage of said data signal corresponding to said desired position.
Claim 4
Dependent Claim
19 words
The electronic timepiece of claim 2, wherein said means for producing on and off control signals is manually operable.
Claim 5
Dependent Claim
39 words
The electronic timepiece of claim 1, wherein said control means further comprises means for causing said driving means to drive said seconds hand alternatively to said indicating position and to a position corresponding to said actual time data signal.
Claim 6
Dependent Claim
46 words
The electronic timepiece of claim 3, wherein said means for performing an auxiliary function includes means for producing a comparison signal when said actual time data signal is identical to said stored data signal and means responsive to said comparison signal for producing an alarm signal.
Claim 7
Dependent Claim
63 words
The electronic timepiece of claim 1, wherein said time base pulses producing means includes means for producing a high frequency signal and means for dividing by a dividing ratio the frequency of said high frequency signal, said means for performing said auxiliary function having adjusting means connected to frequency dividing means for adjusting said dividing ratio in response to said stored data signal.
Claim 8
Dependent Claim
51 words
The electronic timepiece of claim 6, wherein said means for performing an auxiliary function includes means for producing a voltage level detection signal in response to the voltage level of said power source, said means for producing said on and off control signals being responsive to said voltage level detection signal.
Claim 9
Dependent Claim
19 words
The electronic timepiece of claim 6, wherein said means for producing on and off control signals is manually operable.
Claim 10
Dependent Claim
105 words
The electronic timepiece of claim 6, further comprising means coupled to said power source for producing a power source removing signal prior to the removing of said power source and a power source mounting signal after the mounting of said power source, said control means including means responsive to said power source removing signal for causing said motor to drive said seconds hand to said indicating position, said control means further including means responsive to said power source mounting signal for producing a data signal corresponding to said indicating position of said seconds hand and for causing said storing means to store said data signal.
Claim 11
Dependent Claim
61 words
The electronic timepiece of claim 7, further comprising means for producing drive pulses with a power level in response to said time base pulses and means for controlling the power level of said drive pulses in response to said voltage level detection signal, wherein said driving means includes a stepping motor responsive to said drive pulses for driving said seconds hand.
Claim 12
Dependent Claim
46 words
The electronic timepiece of claim 10, wherein said power level controlling means includes means for producing rectangular pulses of a second frequency higher than said first frequency, and means for combining said rectangular pulses and said drive pulses in response to said voltage level detection signal.
