Automatic cut-off setting system for LED display in a solid-state watch

In a battery-operated multi-function electronic watch having a display formed by several light-emitting diode stations, the combination comprising:

• A. a miniature electonic computer having a time base, a frequency divider coupled to said time base to produce low-frequency timing pulses and counters responsive to said pulses for producing signals which are decoded to actuate said stations, said stations normally being in a Normal-mode in which all stations are unactuated;
• B. manually-operated releasable switching means associated with said computer for effecting in a Time-mode the selective actuation of said stations to present Hours-Minutes and other Time-mode functions and in a Set-mode to individually present the various readings constituting said functions, said switching means being constituted by a Time-mode button which when pressed and released in a particular manner produces said Time-mode functions, and a Set-mode button which when repeatedly pressed and released in a particular manner sequentially produces said readings to be set, said readings being thereafter updated by operation of said Time-mode button;
• and
• C. automatic cut-off means associated with said switching means and acting both in the Time-mode and in the Set-mode to cause said display to revert to said normal-mode when said switching means are released or shortly thereafter.
