My understanding is that both used drive lines that either went
through the transformer, or around it, to either couple a drive line
to a sense line, or not. In the case of CRM, the wires are essentially
braided with the cores, while in TROS, holes are punched in strips of
flex circuit to break one of the two paths the drive line can take for
each sense position, and the transformer core is a two-part
rectangular thing rather than a little toroid.
If I'm wrong, or missing some fine point distinguishing them, I'd
welcome corrections or additional information.
