Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
An electronic timepiece comprising, means generating time signal pulses constituting a time base, counting means receptive of said time signal pulses for counting said time signal pulses, means connected to the counting means developing digital outputs representative of time corresponding to at least one of date, day of the week, hour, minute and seconds time indications, display means connected to the means developing digital outputs to diaplay at least one of said time indications, and control means connected to said counting means and said display means for selectively displaying individually said time indications on said display means and including means for selectively setting each of said time indications to a desired value.
Claim 2
Dependent Claim
112 words
An electronic timepiece comprising, means generating time signal pulses constituting a time base, counting means receptive of said time signal pulses for counting said time signal pulses, means connected to the counting means developing digital outputs representative of time corresponding to at least one of date, day of the week, hour, minute and seconds time indications, display means connected to the means developing digital outputs to diaplay at least one of said time indications, and control means connected to said counting means and said display means for selectively displaying individually said time indications on said display means and including means for selectively setting each of said time indications to a desired value.
Claim 3
Dependent Claim
86 words
In an electronic timepiece according to claim 1, wherein said control means comprises, a shift register for storing a control signal therein, switching means connected to said shift register for shifting the position of said control signal within said shift register, and circuit means connecting said shift register to said counting means and said display means For applying said control signal thereto for selectively displaying said time indications and for setting said time indications according to the position of said control signal in said shift register.
Claim 4
Dependent Claim
