A computer is operatively connected to the pump, a power supply is operatively connected to the computer and an auxiliary power supply is operatively connected to the computer. The auxiliary power supply is configured to provide power for a predetermined amount of time if the power supply should fail. A first display has a rear polarizing layer and a front polarizing layer.
