Award-Winning Slide Staining


Sometimes trial and error pays off. Ask Team 1427, who took second place in the Raytheon Sensintel Best Overall Design competition at Engineering Design Day 2015.

With off-the-shelf components, Team 1427 developed a more efficient system for microscopic examination of tissue samples. The system allows for testing a sample at three different temperatures.

“The point of thermal control is that instead of running three different tests under three different temperatures, you can run one thermal test across a single microscope,” said team member Chris Sanford.

The project expands on current slide-staining techniques, in which tissue samples are fixed on to a slide using a technique called "heat-fixing." Once that is done, a dye can then be added to stain the sample so that the cells and cell components are easier to view.

Team members, with the help of mentors Chris Donat, Kenyon Kehl and Steven Lei, had several challenges to overcome – like figuring out which materials would make the vest slide base without contaminating the sample.

Safeguarding Aircraft Generators

Congratulations to Team 1420 for winning the Rincon Research Best Presentation Award at Engineering Design Day 2015. The team developed a new type of electromechanical shaft to disconnect an aircraft generator from the engine output in the event of electrical short or bearing failure.

“The purpose is to save the entire generator from complete failure,” said team member Jose Luttmann. Currently, aircrafts do not have such a device. “We’ve been working on this project since last semester from a concept design that we put into practical use.”

“What they have between the aircraft engine and the generator is a called a shear point,” explained team member Ivy Hasman. “The shear point breaks apart the shaft, so that the engine is still spinning with the generator disengaged, but now there is still a broken shaft.”

The new electromechanical shaft disconnect allows the engine to continue providing power to the aircraft without further damaging the generator. The team is confident that their device can be applied to larger aircraft. 

"Because we are students, we were limited to what we can do, but...
