Solve the following problem: represent as a truth table, extract a function, minimize the function, and implement in gates:

You are part of an engineering team to build an appliance, your job is involved with the digital logic controlling the heating of an automatic electric coffee/tea pot. A fail-safe circuit protects the pot and heating element from overheating based on a number of True/False conditions. The heating element should only be able to be energized when: the device is turned-on, the timer is above zero (it is counting down), the pot is on the heating surface (determined by the weight of the pot resting on the heating surface), and there is water in the pot (determined by weight above that of the pot),
