Abstract
Abstract An electronic watch with an electronic display of time fed from a counting circuit via a transcoder comprises a data input device including a manual control member for transferring at least one element of displayed data by means of a logical transfer circuit. For example, a number indicated on a separate display by means of a separate counter can be selectively transferred to replace any particular number in the display of time to thereby set the time. Alternatively, an indication of a first unit of time (e.g., seconds) can be transferred to replace and thereby correct an indication of a second unit of time (e.g., hours), a supplementary impulse generator selectively accelerating the sequential indication of seconds.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
180 words
An electronic watch, comprising: a time base; an electronic display means; a logic circuit having an input coupled to an output of said time base and an output coupled to an input of said display means, said logic circuit including a first counting circuit and transcoding means coupling the output of said first counting circuit to said display means; data input means coupled to a further input of said logic circuit for selectively transferring data signals to said further input, said data input means comprising a pulse generator, first manual control means for controlling the output of said pulse generator, and a second counting circuit coupled to the output of said pulse generator; second manual control means coupled between the output of said second counting circuit and said further input of said logic circuit for selectively transferring data from said second counting circuit to said logic circuit; and a selection circuit coupled to said first counting circuit and said transcoding circuit for selectively controlling the display of the outputs of said first and second counting circuits on said display means.
Claim 2
Dependent Claim
180 words
An electronic watch, comprising: a time base; an electronic display means; a logic circuit having an input coupled to an output of said time base and an output coupled to an input of said display means, said logic circuit including a first counting circuit and transcoding means coupling the output of said first counting circuit to said display means; data input means coupled to a further input of said logic circuit for selectively transferring data signals to said further input, said data input means comprising a pulse generator, first manual control means for controlling the output of said pulse generator, and a second counting circuit coupled to the output of said pulse generator; second manual control means coupled between the output of said second counting circuit and said further input of said logic circuit for selectively transferring data from said second counting circuit to said logic circuit; and a selection circuit coupled to said first counting circuit and said transcoding circuit for selectively controlling the display of the outputs of said first and second counting circuits on said display means.
Claim 3
Dependent Claim
152 words
Data input apparatus for use in an electronic watch having a time base, a logic circuit, an input of which is coupled to an output of said time base, and an electronic display means coupled to an output of said logic circuit, said apparatus comprising: a counting circuit; manual control means coupled to the input of said counting circuit for manually stepping said counting circuit; further display means for displaying the output of said counting circuit; memory means for storing an output of said counting means in the form of logic instructions; and data transfer means coupling the output of said counting means to a further input of said logic circuit, said data transfer means being further coupled to and controlled by the output of said memory means, wherein data is transferred from said counting means to said logic circuit as a function of the logic instructions stored in said memory means.
Claim 4
Dependent Claim
152 words
Data input apparatus for use in an electronic watch having a time base, a logic circuit, an input of which is coupled to an output of said time base, and an electronic display means coupled to an output of said logic circuit, said apparatus comprising: a counting circuit; manual control means coupled to the input of said counting circuit for manually stepping said counting circuit; further display means for displaying the output of said counting circuit; memory means for storing an output of said counting means in the form of logic instructions; and data transfer means coupling the output of said counting means to a further input of said logic circuit, said data transfer means being further coupled to and controlled by the output of said memory means, wherein data is transferred from said counting means to said logic circuit as a function of the logic instructions stored in said memory means.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 1, comprising second manual control member means which, when actuated, transfers the data displayed by said further display means to said memory means.
