I was thinking about this the other (past few months)
Getting into _that_ industry, I mean.
I was wondering specifically if it might be possible to get some existing medical devices to communicate via bluetooth with a central server; to build an adapter so everything that sent out a vital signal was logged on disc and remotely accessible in real time.
I was in a hospital recently, and the vital signs were logged on paper, and abnormalities were signaled by a loud alarm, to be audible at the nearby nurses station.
But I don't know how I can 'weekend hack' this sort of thing. Perhaps I can grab some medical surplus, a bluetooth adapter and start hacking?
