Multifunction sequence operated integrated switch-display device
First Claim
1. A combined display-selector device for electronic data transmission systems comprising:
- digital display means responsive to electronic actuation to provide a visual display of a numeric symbol on the face thereof;
switch means physically interconnected with said display means and responsive to manual contact with the face of said display means to assume a condition to pass an electrical signal;
a counter having an input for receiving electrical pulses and outputs for presenting in electrically coded form a signal representing the number of pulses received by said counter;
a pulse source connected to the input of the counter through said switch means whereby manual contact with the display means advances the count;
and means for connecting the outputs of the counter to the display means to advance the numeric display, said means being further adapted for connection to an external device.

Abstract
A contact responsive integrated switching and display system intended as an improvement to electromechanical devices such as rotary switches. The switching device controls the sequencing of displayed characters, by controlling gating of clock pulses into a counter, with activation of a function (such as selection of a circuit) corresponding to a selected displayed character produced by release of the switching device and discontinuance of the sequencing. The switching device is disclosed as physically directly associated or integrated with the display. The switch/display device can be self-contained or can be integrated in a system such as computer-data processing applications. An application of the device to data programming of a computer system is disclosed, in which a multidigit display is interfaced with a computer for operation in computer display, count advance and computer input modes. For each digit of the display, contact with the face of the display element gates clock pulses into a counter. The contents of the counter may be selectively displayed and/or output to the computer by way of a bidirectional data bus. The computer has a digit selection capability. The mode selection switch is implemented as a contact responsive visual display element.

8. A multidigit data selection and display system comprising:
-
first and second digital display devices responsive to electronic actuation to provide a visual display of numeric symbols on the faces thereof; first and second switch means operatively interconnected with the first and second display devices, respectively, for providing respective enabling signals when said faces are manually contacted; first and second counters each having an input for receiving clock pulses and outputs representing the count therein; a clock pulse source; first and second gate means connecting said source to each of the counters and being further respectively connected to receive said enabling signals from the first and second display devices to gate and block the application of clock pulses to the counters according to the presence and absence respectively of said manual contact; and selectively controllable transmission gates for connecting the counter outputs to the display devices to actuate same for display of the counts. - View Dependent Claims (9, 10, 11, 12)

13. A multifunction sequence operated integrated switch display device comprising:
-
counter means; means for sequencing a series of digital signals into said counter means; display means producing a sequential character display corresponding to each of said series of digital signals; switching means physically integrated with said display means manually operable to control said sequencing of digital signals into said counter means by discontinuing said sequencing upon release of said switching means and retaining the selected digital signal in said counter means and continued display of said character corresponding to said selected digital signal; and
,means for connecting said counter means to an external device to transmit said selected counter to said device.
