* Larry Beaty: has been wearing the A&D Sphygmomanometer.
El asked if it was accurate. Larry said it produces both a Korotkoff
and acoustic measurement and they may differ by 5-8 mmHg. El asked
how they satisfy the ANSI requirements. Bob asked if they satisfy
the requirements. If they don't make claims, they do not have
requirements. Chris noted that the accuracy standards specified
the patient was a rest for 10 minutes.

What is a description of what would measure this?
* Measure the change in the size of the wrist, caused by change
in the size of artery. Two signals from Piezoelectric to combine
to an A-to-D convert, and clock. Store the D signal that is stored
with timestamp into a chip register (circular FIFO), loosely called
a processor. This provides a sensor that produces blood pressure.
Result: we described a framework for understanding the relationship
between sensors and measurement, and a problem with modeling approach
(multiple centers and simultaneously perform architecture and
design).
