I feel like I'm missing a simpler way, but this one should do the trick 
(see attachment).

The delay amount determines the maximum time that can elapse between the 
bangs of the two sensors. If a single bang is received from one sensor 
and the other doesn't arrive within that time, the "orphan" bang will be 

Is it what you were looking for?
