5. Consider automatic doors that open and close at the grocery store. Sensors on the ground tell the door when to open and close. a. Describe the operation of a one-way door. Each sensor provides a binary input indicating whether or not a person is there. Specifically, identify the different states the operation might be in (e.g. both sensors off, door closed or one sensor on, door open, etc). Figure out the transitions between states and what the triggers for the transition are. b. Design a circuit to implement this state machine. These doors have sensors on both sides because (1) the door should not hit anyone standing outside, and (2) you don't want the door to close in somebody's face. To clarify, you are only designing the circuit for one door. These doors are typically installed in pairs, one for "in" and one for "out". Each door will have its own circuit

Transcribed Image Text:5. Consider automatic doors that open and close at the grocery store. Sensors on the
ground tell the door when to open and close.
a. Describe the operation of a one-way door. Each sensor provides a binary input
indicating whether or not a person is there. Specifically, identify the different states the
operation might be in (e.g. both sensors off, door closed or one sensor on, door open,
etc). Figure out the transitions between states and what the triggers for the transition are.
b. Design a circuit to implement this state machine. These doors have sensors on both
sides because (1) the door should not hit anyone standing outside, and (2) you don't want
the door to close in somebody's face.
To clarify, you are only designing the circuit for one door. These doors are typically
installed in pairs, one for "in" and one for "out". Each door will have its own circuit
