PROBLEM STATEMENT

In order to simultaneously collect emissions and transport undisturbed casts for analysis, current hollow cast models will be combined with the existing side stream smoking machine. Device will operate using acquired data from the wPSMD. Unit needs to be self-contained, portable, fit on a workbench, and user friendly. The unit must also be production ready for identical machines in other labs. During operation smoke needs to be ventilated responsibly and the unit must be interfaced with LabVIEW.

PROBLEM STATEMENT(BULLET FORM)

Smoke single Cigarette Smoke travels through

main-stream lung casting while the side-steam machine captures the remaining smoke

Smoke that travels through the lung casting will be recirculated through the side-stream machine (2nd hand smoke)

Unit will fit on a portable cart Samples will be taken to the

NTID lab for analysis 12-10-13 Team 14054 9
