摘要：
An output apparatus includes a first source of a first signal having a first state or a different second state; a second source of a second signal having a first state or a different second state; and a circuit structured to output a vital output including a first state when the first state of the first signal corresponds to the first state of the second signal and, otherwise, including a different second state. At least one of the first signal and the second signal is a static signal. The other one of the first signal having the first state and the second signal having the first state is a dynamic signal. When at least one of the first signal has the different second state of the first signal and the second signal has the different second state of the second signal, the vital output includes the different second state.
