2 Who Are We? Twin Cities IEEE Phoenix Project – Volunteer electrical/mechanical/software engineers – Our group was assembled to productize results of research done at the Chronobiology Lab and elsewhere – Open Source hardware project to design and build a blood pressure monitor that is inexpensive, unobtrusive, easy to use and collects a week of blood pressure measurements. – Details: http://www.phoenix.tc-ieee.org/http://www.phoenix.tc-ieee.org/ UMN Halberg Chronobiology Lab – Dr. Franz Halberg, “Father of American Chronobiology” – Chronobiological Interpretation of Blood Pressure Vascular Variability Disorders more important than hypertension – Our “customer” – Details: http://www.msi.umn.edu/~halberg/http://www.msi.umn.edu/~halberg/ Copyright 2013, 2014 Larry A. Beaty. Copying and distribution of this document is permitted provided this notice is retained.

3 What needs to be done? Improve the accuracy of blood pressure readings by determining where the monitor is relative to the heart. – Most efficient when the monitor is at the same level as the heart. Use location technologies than are well understood and available as off-the-shelf (OTS) products and/or components. −RFID −Wireless LAN Copyright 2013, 2014 Larry A. Beaty.

5 Visualization Looking for “h” Yep, it’s that “simple.” Copyright 2013, 2014 Larry A. Beaty. Copying and distribution of this document is permitted provided this notice is retained.

6 RFID Technology Powered transciever Powered or unpowered “tag” circuit on the object to be identified Designed to identify objects, not necessarily to locate them. But, there is work being done elsewhere to use RFID for locating tags. Copyright 2013, 2014 Larry A. Beaty. Copying and distribution of this document is permitted provided this notice is retained.

8 Activities in the sensor project Measure and reverse engineer previous prototype Redesign 3 subcircuits to improve estimate of h Build new prototype and test jig Test new prototype, quantify results Deliver design files and prototype, and publish a final report that will be posted on the Phoenix Project website. (Can be the same as your class report.) Additional “stretch goals” available Copyright 2013, 2014 Larry A. Beaty. Copying and distribution of this document is permitted provided this notice is retained.

9 Phoenix Project Resources We work in the IEEE student lab (Keller Hall, 2- 110) In-the-lab or on-Skype meetings on Saturdays 10:00 to 1:00 We have worked with students before Equipment in our lab on campus Academic papers (or do your own searches) Previous student projects Copyright 2013, 2014 Larry A. Beaty. Copying and distribution of this document is permitted provided this notice is retained.

10 Conclusion We are looking to extend the R&D we’ve done so far, and then productize something from the ongoing research; the student projects are an important part of that. Dr. Halberg expects this to change healthcare in a major way for all 7 billion people on the planet by preventing and diagnosing diseases we can’t detect today. Would you like to say that you got an “A” for doing your part on an open source healthcare-related project that went from visualization in the academic world to R&D and then to production? – Companies like to hire people who can say stuff like that!
