Improve project schedule with added in deliverables

Goal- receive an approved system level design by week 6

review

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.

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
