The flow of water causes the turbine in the power generator to rotate. This process generates
electric power and enables the automatic Flush Valve to operate. See ill. 1 below.

The Fuzzy Logic Control function automatically adjusts the discharge of water according to the
frequency and duration of usage (see ill. 2 and ill. 3).
The Fuzzy Logic
Control system judges
the frequency of
usage by the idle time
of the fixture and
causes the Flush Valve
to discharge water in
an optimal flushing
pattern.
The Fuzzy Logic Control
system predicts the
quantity of flush water
needed based on the
user's duration of use.

If the idle time is short, the system assumes frequent use
and the Flush Valve discharges less water.
Examples of high frequency use would be during a lunch
break or an intermission in a movie theatre.
Long duration of usage
A long duration of use indicates
Typical
there may be more to flush,
requiring the Flush Valve to
deliver a typical quantity of flush
water for thorough flushing.
