Great find, Jeff! I'm also finding it called "Digital Pulse Interval
and Width Modulation" with the same acronym. I think it is clearer with
the "and" in there, and that version of the name dates back at least to
1995.

After way to much searching ... under Anisochronous modulation, there is
something called Digital Pulse Interval Width Modulation (DPIWM).

Seems like as good a name as any.

I though NRZI had a constant symbol rate. I would expect 011101001 in
NRZI to look like:

Hey Mike,
I think that NRZI.

A friend recently showed me an OOK modulation that I had never seen
before, and I'm wondering if anyone knows a name for this scheme.
It is PWM where both the on periods and off periods carry data in their
durations.
In the example we observed, an on or off period with a duration of two
units rep
