Height Adjustment - Preliminary Testing

10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 12

● Stage found in the lab● Has relatively fine

adjustment● Need to fabricate base

plate to mount it securely to the isolation table

● For flexibility of injection system to allow for needle to move chose brake lines

● Can withstand high pressures (3,000psi+)

● “Stainless Steel” lines have teflon tube to carry brake fluid, covered by stainless steel mesh for protection

● Robust and cost effective

The Oscillator - Preliminary Testing

10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 16

● Approached Dr. Lam to discuss speaker dampening ● Two really important points

○ Added noise in graphs due to lights■ No way to get rid of that■ Can implement a filter to reduce the noise

○ We should be wearing earplugs!! ■ Certain frequencies can be damaging to our ears ■ All feasibility testing was done wearing earplugs

● Joe and Alyssa will design a fixture to hold the speaker and test oscillations○ Rob will construct the fixture ○ Collecting data

■ Need to make sure the meniscus is oscillating at the same frequency that the speakers are outputting● Using high speed cameras and consulting

experts ● Feasibility analysis on the capacitance sensor with

oscillations ● Purchasing brake lines and stainless steel syringe● Rearranging system layout ● Baking more cookies and a bike ride
