Abstract
Abstract An electronic timepiece having a minute hand and an hour hand which are controlled by a control circuit of the timepiece to display and to program, in addition to their own parameters, other parameters such as date, month, second, alarm time, or other, non time-related, parameters, which can be selected by push-button or pull-switch control means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
An electronic time piece comprising: means for producing time base pulses; means responsive to said time base pulses for producing a plurality of time signals; a minute hand; means coupled to said minute hand for producing a signal representative of the position of said minute hand; means responsive to a first manual action for producing a first manual command; means responsive to said first manual command for selecting one of said time signals; means responsive to said selected one of said time signals and to said minute hand position signal for producing a first comparison signal whenever said one selected time signal is unequal to said minute hand position signal; means responsive to said first comparison signal for producing driving pulses; means responsive to said driving pulses for driving said minute hand, thereby causing said minute hand to be driven to a position corresponding to said one selected time signal in response to said first manual command.
Claim 2
Dependent Claim
157 words
An electronic time piece comprising: means for producing time base pulses; means responsive to said time base pulses for producing a plurality of time signals; a minute hand; means coupled to said minute hand for producing a signal representative of the position of said minute hand; means responsive to a first manual action for producing a first manual command; means responsive to said first manual command for selecting one of said time signals; means responsive to said selected one of said time signals and to said minute hand position signal for producing a first comparison signal whenever said one selected time signal is unequal to said minute hand position signal; means responsive to said first comparison signal for producing driving pulses; means responsive to said driving pulses for driving said minute hand, thereby causing said minute hand to be driven to a position corresponding to said one selected time signal in response to said first manual command.
Claim 3
Dependent Claim
132 words
The electronic time piece of claim 1, further comprising means for producing a plurality of time independent signals, said first manual command producing means being further responsive to a second manual action preceding said first manual action for producing a second manual command, said selecting means being further responsive to said second manual command for selecting one of said time independent signals, and said first comparison signal producing means being further responsive to said selected one of said time independent signals and said minute hand position signal for producing said first comparison signal, thereby causing said producing means to produce said driving pulses and said driving means to drive said minute hand to a position corresponding to said selected one of said time independent signals in response to said second manual command.
Claim 4
Dependent Claim
45 words
The electronic time piece of claim 1, further comprising means responsive to a third manual action for producing a correction command and means coupled to said selecting means and responsive to said correction command for setting said one selected time signal to a desired value.
Claim 5
Dependent Claim
141 words
The electronic time piece of claim 1, wherein said plurality of time signals producing means comprises minute signal producing means and hour signal producing means, further comprising an hour hand drivingly engaged with said minute hand, means coupled to said hour hand for producing a signal representative of the position of said hour hand, and means coupled to said selecting means and responsive to said hour signal and to said hour hand position signal for producing a second comparison signal whenever said selected one of said time signals is said minute signal and said hour signal is unequal to said hour hand position signal, said driving pulses producing means being further responsive to said second comparison signal for producing said driving pulses, thereby causing said driving means to further drive said hour hand to a position corresponding to said hour signal.
Claim 6
Dependent Claim
41 words
The electronic time piece of claim 1, wherein said minute hand position signal producing means comprises a first counter, and further comprising means coupled to said minute hand for resetting said first counter whenever said minute hand reaches a predetermined position.
Claim 7
Dependent Claim
41 words
The electronic time piece of claim 4, wherein said hour hand position signal producing means comprises a second counter, and further comprising means coupled to said hour hand for resetting said second counter whenever said hour hand reaches a predetermined position.
Claim 8
Dependent Claim
134 words
The electronic time piece of claim 3, wherein said plurality of time signals comprises at least a minute signal, and further comprising means for producing at least a minute alarm signal and means responsive to said minute alarm signal and to said minute signals for producing an alarm output signal when said minute signal equals said minute alarm signal, said selecting means being coupled to said minute alarm signal producing means and operable to select said minute alarm signal in response to said first manual command, thereby causing said minute hand to be driven to a position corresponding to said selected minute alarm signal in response to said first manual command and enabling said minute alarm signal producing means to be set to a desired value in response to said manual time correction command.
