12

• Well over a dozen DMT’d parts– Cougar, Condor, Adgressor, Advenger,

* Control Boards, Pump Controllers, Interface Assemblies• Several TFR’d parts• Provided support for teammates TFRs

– Blue Phoenix aka Focus II Rider– CS7000 aka Cougar– Well over 100 pictures of waveforms

Testing

13

• Issue– Pin 11 on chip U27 failing

• Problem Observed– High voltage spikes seen on pin 11 above

rated tolerance are deteriorating it• Potential Cause

– Higher voltages are being induced on pin 11 trace from a nearby high voltage trace

– Actuator runs and causes spiking from back EMF

• Actions– Unable to test HV trace properly and is almost

certainly the cause– Test actuators to eliminate as a possibility

Testing Cont. – Cougar

14

• As much work to support products after their release• Length of time for bringing a new machine to market• The most important question to ask “What’s the goal?”• Knowledge about the cleaning industry• Interdependence of the departments and fields• An electrical engineer is….a lot of things….

What I learned

15

• Flexible Hours• Weekly team meetings• Mentor to ask questions to• Ability to ride machines!

Recommendations to Keep

16

• Give one big project to finish by the end of summer along with small ones

• Shadow different departments for a day

• More Lunch-n-Learns

Recommended Changes

17

• Finish degree at University of Minnesota – Twin Cities

• Grad School?• Full-Time then grad school?• Start-Up Company?• Retirement?
