That "search google for more" disturbs me!
One type of unipolar encoding commonly used, but which I can't find info on in Wikipedia, --or anywhere else for that matter--, is where the bit time is divided in three parts. If the three parts are represented as bits, a 1 in the data would be encoded as 110, and a 0 as 100. It is a return to zero scheme with good synchronization, as the 0-to-1 transitions are on constant time, serving as synchronization reference, --with data being carried by 1-to-0 transitions. Many devices using 433MHz ASK ISM band use this code. Problem for someone like me, I need to write code for a receiver, but I find no info reference, and even what the name of this encoding is I do not know.
