An applicator dispenser has a container defining a tank with a lateral wall and a neck integral with a wiper. In particular, the microstructure device includes a substrate and a movable structure suspended above the substrate by at least one anchor. The method also includes scheduling one of the IO requests with at least one of the plurality of IO schedulers. One amplifier with a PMOS transistor and one resistor string provides a higher pseudo power supply, and the other amplifier with an NMOS transistor and the other resistor string provides a lower pseudo power supply so that a digital functional section is coupled between these pseudo power supplies. Piezoelectric actuator expansion drives the piston to pressurize the fuel in the pressurization chamber, which forces open a conical annular valve and nozzle assembly injecting a finely atomized mist of fuel into the cylinder.
