ll. 23-26. The coded time signal is used to update the time
shown by the hands of a watch. Van Orsdel describes the
update as follows.
The normal timekeeping mode operates through
suitable coded signals received at antenna 19. A
receiver 22 of conventional design decodes and
amplifies the signal which it receives and converts
it into a direct current (DC) pulse.... The DC
pulse generated by receiver/amplifier 22 is driven
to a timekeeping mode output 25 and through suitable
conductive means to a micro-relay switch 26.
Activation of switch 26 feeds the DC pulse to a
known set-reset, flip-flop circuit 27 which
activates a step motor 28. Step motor is
mechanically connected to a conventional watch gear
set 29 which moves the hands of the watch.
Col. 2, ll. 53-67.
The reference further teaches, "[t]he separate
synchronization signal is transmitted, for example from
satellite 11, at a relatively long time interval such as once
each hour or once each day." Col. 3, ll. 39-41. The
synchronization signal is converted into a time update signal.
More specifically, "[t]he synchronization signal is received
at antenna 19 and directed to receiver/amplifier 22. The
signal is amplified and converted into a DC pulse having
