In other words, a wide white bar might be 14 ones, a narrow white bar might be 6 ones, a narrow black bar might be 7 zeros and so on. The number of ones or zeros would depend on the bar thickness and scan rate, so once again its up to the software decoding the bar code to figure out what's what.

It's interesting to look at the Cue Cat bar codes. They put a black triangle before and after the bar code, and I would expect that this allows the software to calculate roughly what the scan rate is, making the decode of the bars themselves simpler. The advantages of designing your own bar code, rather than conforming to an existing standard.
