3 Agenda Action Items Test Configurations Price Comparison Modeling Analysis Updated Concept Bill of Materials Specifications of Components Updated Project Risks Community Outreach Events and Competitions Future Plans/Key Deliverables

4 Action Items from Systems Design Review Add breathability to customer/engineering requirements Owner: Jared Progress: Not feasible to include in rig - Confirmed with ID students Test for garment/skin contact in regards to flexibility Owners: Team Progress: Postponed due to waiting for BME department lab access. Will be resumed when access is granted. Follow up with Xerox on using environmental control chamber Owner: Crystal Progress: Postponed until ready for testing phase Investigate places on RIT campus where environmental testing can be done Owners: Team Progress: Complete - hot and cold locations identified

5 Test Configurations Mathematical Model Simulated Tissue Human Model Attempting to Determine: Effective cooling time Rate of cooling Relevant temperatures

6 Mathematical Model Ideal model Assumes -D Heat transfer Assumes external insulation eliminates any loss to environment Will give us values for duration and rate cooling Requires material specifications and hand calculation

7 Simulated Tissue Physical recreation of mathematical model Exposes system to external environment Requires tissue substitute High repeatability Enables objective comparison of different cooling systems Can be conducted with minimal human interaction Key T Qgen Tsurf Tpcm Tskin Tcore Air Temp Heat generated from body Surface Temperature Phase change temperature Skin Surface temperature Human Core temperature

8 Human Model Requires human to wear cooling system for duration of test Values may vary person to person Enables human feedback Key Tsurf Tpcm Tskin Tcore Surface Temperature Phase change temperature Skin Surface temperature Human Core temperature

10 Concept Selection: The All-in-One Features - Inexpensive Easy to use Records and saves data Realistic Changes - Software: LabChart to PASCO Weight will be measured with cooling device only
