The GATE *events* could be like the following:
ON....OFF...........ON.OFF............ON.............................OFF...
all produced in a short period of time (for example < 500msec.)
and delayed of 3 sec for example again.
That's why the *shift register* approach should be able to register all these
so called events without missing one.
