4 if the pressure valve is ON then sensor monitor pressure is VALID,else if pressure valve is transitioning from ON to OFF then sensor monitor pressure is HOLD,else monitor pressure is INVALID

if(pressure valve is ON)

else if (pressure valve is transitioning from ON to OFF)

else (monitor pressure is INVALID)

if(pressure valve is ON){sensor monitor pressure is VALID}

else if (pressure valve is transitioning from ON to OFF){sensor monitor pressure is HOLD}

else {monitor pressure is INVALID}

if(pressure valve is ON){sensor monitor pressure is VALID}

else if (pressure valve is transitioning from ON to OFF){sensor monitor pressure is HOLD}

else {monitor pressure is INVALID}

5 the sysytem works if and only if all the sensors are connected.the environmental effects ,malfunction of sensors may have effects on the system

if(system works ON)

else(environmental effects ,malfunction of sensors may have effects on the system)

if(system works ON)

{all the sensors are connected}

else{environmental effects ,malfunction of sensors may have effects on the system}

if(system works ON)

{all the sensors are connected}
