Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A device for controlling the display of an electronic watch capable of supplying two sets of information of different types, comprising means for producing a control signal, a selection circuit permitting the selection of the information which is to be displayed under control of said control signal, a controllable interface controlled by said control signal, the interface being controllable for selection and modification of the appearance of the display according to the nature of the displayed information, and the interface comprising a gate logically adding together two trains of pulses, derived from a timing circuit and the control signal, said gate having an output capable of actuating a plurality of gates through which the items of information to be displayed pass and capable of causing a perceivable blinking of the display.
Claim 2
Independent Claim
131 words
A device for controlling the display of an electronic watch capable of supplying two sets of information of different types, comprising means for producing a control signal, a selection circuit permitting the selection of the information which is to be displayed under control of said control signal, a controllable interface controlled by said control signal, the interface being controllable for selection and modification of the appearance of the display according to the nature of the displayed information, and the interface comprising a gate logically adding together two trains of pulses, derived from a timing circuit and the control signal, said gate having an output capable of actuating a plurality of gates through which the items of information to be displayed pass and capable of causing a perceivable blinking of the display.
Claim 3
Dependent Claim
81 words
A device as claimed in claim 1 wherein said controllable interface is responsive to the absence of said control signal to continuously direct the selected one set of information to said display and said controllable interface is responsive to the presence of said control signal and two other different frequency signals derived from said timing circuit, to intermittently direct the selected other set of information to said display at a rate such that said display blinks at a readily perceivable frequency.
Claim 4
Dependent Claim
153 words
An electronic timepiece comprising a display allowing alternative indication of the time and of chronographed time intervals, a time counting circuit and a chronograph circuit, a controllable selection circuit for selection of the information which is to be displayed either from said time counting circuit or from said chronograph circuit, decoder means responsive to said selected information for controlling said display to display the corresponding time or time interval, an interface electrically coupled to the output of said decoder means and being controllable for modification of the appearance of the display, means for generating a control signal and means for generating a blinking signal, said control signal acting simultaneously on said selection circuit and on said interface and said blinking signal acting on said interface, for control of a continuous display when said time counting circuit is selected for display and a perceivably blinking display when said chronograph circuit is selected for display.
Claim 5
Dependent Claim
153 words
An electronic timepiece comprising a display allowing alternative indication of the time and of chronographed time intervals, a time counting circuit and a chronograph circuit, a controllable selection circuit for selection of the information which is to be displayed either from said time counting circuit or from said chronograph circuit, decoder means responsive to said selected information for controlling said display to display the corresponding time or time interval, an interface electrically coupled to the output of said decoder means and being controllable for modification of the appearance of the display, means for generating a control signal and means for generating a blinking signal, said control signal acting simultaneously on said selection circuit and on said interface and said blinking signal acting on said interface, for control of a continuous display when said time counting circuit is selected for display and a perceivably blinking display when said chronograph circuit is selected for display.
