But isn't the clinical definition of death, brain death, as the heart
may stop but the person be resuscitated tens of seconds later. In our
terms, tens of seconds is like a lifetime so heatbeat is out as the
TOD metric. I would propose we develop a hat with inbuilt electrodes
that touch the scalp and measure brain activity. Once this has decayed
to the level as clinically defined as brain dead, a timestamp should
be made against a standard that is reasonably accurate to the degree
of uncertainty of the death event, IE. it is likely that the brain
activity will stop instantly with such a sharp cutoff as to be less
than a ms, us or whatever. The hat would include an integrated GPSDO
built upon a flexible PCB board design with integrated path antenna
positioned at the top. This could easily be powered by solar cells
charging very thin lithium ion flexible batteries embedded in the hat.
Of course the hat needs to be worn 24x7 so it would have to be of a
design that lends itself to sleeping hours as well therefore being a
sleeping cap so something like a beanie may be a starting point.
Extensions to the design may be a time display which would, of course,
double as the TOD display for those concerned with your internment and
the engraving of your tombstone. A PPS and disciplined oscillator
connection could also be incorporated as a form of mobile reference
for the wearer. As for cleaning, two of such hats would be owned by
the user with one "in the wash" while the other is being worn. Of
course, careful planning and design needs to be taken in the choice of
circuitry and construction so as to all the hat to be cleaned. There
is, of course, the faint possibility of death during the swapping of
but some careful planning of how to do the hat swap may alleviate this
window.
