Peugeot TYP frame - details please

[El10]

Hi -can anybody tell me anything about Peugeot Technology Yoke Power (T.Y.P.) frames? I have one which is yellow with the odd blueish flash, approx 55cm, and the downtube is slightly curved. The Peugeot lion headbadge on it is rectangular. I'd be grateful for any information about it. What is "Yoke Power" anyway?

I might be wrong, but I believe it meant the bottom bracket area is uniquely strengthened by a one-piece CNC machined unit:

Thanks. Yes, that's what it looks like. Any further info out there -when was this design introduced etc.?
