 We can make this a general case by taking a set $F$ (where $f1, f2 \in F$) representing a collection
 of component failure modes.
 We can define a boolean function {\ensuremath{\mathcal{ACTIVE()}}} that returns 
-whether the fault mode is active (true) or dormant (false).

 We can say that if any pair of fault modes is active at the same time, then the failure mode set is not
 unitary state:
