RE: [IPk] Re: glucowatch
The next version of the watch might contain a similar chip to the MiniMed
508 remote control, and "broadcast" the bg estimation to the pump. If the
pump contains some new software, it can use that information to make
I accept that the software would not be simple, but, with appropriate
caution, it could make good use of the data. We might still have to
manually program a bolus when we eat - since it might be somewhat late to
wait for the bg to rise before bolussing - but I would be more than happy
to let my pump take over the constant tweaking and fiddling with basal
Or am I missing something here?

Hi, I've been watching all this with great interest; this in particular is
very similar to an idea I came up with very shortly after Liz went on the
pump 2 months ago.
The interface between continuous BG monitor and pump could actually be very
How simple? Well, a lower-second rate (sorry, class) engineering student
would be able to make one using just a few quid's worth of components from
the RS catalogue. A more computer literate student would be able to write
perfectly suitable software to do the same job but with fewer chips and less
How do I know? Six years ago, I was that lower-second class engineering
student (Loughborough Uni, BEng Electronic & Electrical Engineering, 2.ii,
if you're at all interested). The main part of my final year project was a
dead-band comparator, which is basically what is needed. In this application
you'd probably want four limits, two above and two below a target BG, to
give first a warning then an alarm, with suitable responses from the pump to
go with each and/or to let you know to eat something.
Obviously you'd want to retain a manual over-ride for meal boluses and the
unit would have to take these into account, however the basic system would
be very simple.
I still have the project report too, but only in hardcopy!
